1Individualized prediction of perineural invasion in colorectal cancer: development and validation of a radiomics prediction model显示文摘Objective: To develop and validate a radiomics prediction model for individualized prediction of perineural invasion(PNI) in colorectal cancer(CRC).Methods: After computed tomography(CT) radiomics features extraction, a radiomics signature was constructed in derivation cohort(346 CRC patients). A prediction model was developed to integrate the radiomics signature and clinical candidate predictors [age, sex, tumor location, and carcinoembryonic antigen(CEA) level]. Apparent prediction performance was assessed. After internal validation, independent temporal validation(separate from the cohort used to build the model) was then conducted in 217 CRC patients. The final model was converted to an easy-to-use nomogram.Results: The developed radiomics nomogram that integrated the radiomics signature and CEA level showed good calibration and discrimination performance [Harrell's concordance index(c-index): 0.817; 95% confidence interval(95% CI): 0.811–0.823]. Application of the nomogram in validation cohort gave a comparable calibration and discrimination(c-index: 0.803; 95% CI: 0.794–0.812).Conclusions: Integrating the radiomics signature and CEA level into a radiomics prediction model enables easy and effective risk assessment of PNI in CRC. This stratification of patients according to their PNI status may provide a basis for individualized auxiliary treatment.Yanqi Huang Lan He Di Dong Caiyun Yang Cuishan Liang Xin Chen Zelan Ma Xiaomei Huang Su Yao Changhong Liang Jie Tian Zaiyi Liu 2018Chinese Journal of Cancer Research2018,30,1:23
2NIR-induced highly sensitive detection of latent finger- marks by NaYF4:Yb,Er upconversion nanoparticles in a dry powder state显示文摘通常在犯罪场面发现 fingermarks 的大多数是潜伏的并且,这样为检测潜伏的 fingermarks 的一个有效方法是很重要的。然而,传统的发展中技术有象低察觉敏感,高背景干扰,复杂操作,和高毒性那样的缺点。处理这挑战,我们采用了荧光灯 NaYF 4:Yb,Er upconversion nanoparticles (UCNP ) 它能发荧光可见的光什么时候由 980 nm 使对人安全的在红外线附近的光激动,到污点,各种各样的底层上的潜伏的 fingermarks 出现。 UCNP 成功地被用作一篇小说荧光灯为有包括非渗入的材料(玻璃,大理石,铝合金表,不锈钢表,铝陪衬,和塑料卡片)的各种各样的底层上的高敏感,低背景,高效率,和低毒性的潜伏的 fingermarks 的察觉的标签,渗入半的材料(地板皮革,陶器的瓦,木头地板,和油漆木头),和象报纸的各种各样的类型那样的渗透的材料。这个工作证明 UCNP 是一万用荧光灯为几乎任何东西上的 fingermarks 的灵巧的察觉的标签材料,在法庭的科学启用他们的实际应用。Meng Wang Ming Li Mingying Yang Xiaomei Zhang Aoyang Yu Ye Zhu Penghe Qiu Chuanbin Mao 2015Nano Research2015,8,6:20
3Whole-genome sequencing of 508 patients identifies key molecular features associated with poor prognosis in esophageal squamous cell carcinoma显示文摘Esophageal squamous cell carcinoma(ESCC)is a poor-prognosis cancer type with limited understanding of its molecular etiology.Using 508 ESCC genomes,we identified five novel significantly mutated genes and uncovered mutational signature clusters associated with metastasis and patients’outcomes.Several functional assays implicated that NFE2L2 may act as a tumor suppressor in ESCC and that mutations in NFE2L2 probably impaired its tumor-suppressive function,or even conferred oncogenic activities.Additionally,we found that the NFE2L2 mutations were significantly associated with worse prognosis of ESCC.We also identified potential noncoding driver mutations including hotspot mutations in the promoter region of SLC35E2 that were correlated with worse survival.Approximately 5.9%and 15.2%of patients had high tumor mutation burden or actionable mutations,respectively,and may benefit from immunotherapy or targeted therapies.We found clinically relevant coding and noncoding genomic alterations and revealed three major subtypes that robustly predicted patients’outcomes.Collectively,we report the largest dataset of genomic profiling of ESCC useful for developing ESCC-specific biomarkers for diagnosis and treatment.Yongping Cui Hongyan Chen Ruibin Xi Heyang Cui Yahui Zhao Enwei Xu Ting Yan Xiaomei Lu Furong Huang Pengzhou Kong Yang Li Xiaolin Zhu Jiawei Wang Wenjie Zhu Jie Wang Yanchun Ma Yong Zhou Shiping Guo Ling Zhang Yiqian Liu Bin Wang Yanfeng Xi Ruifang Sun Xiao Yu Yuanfang Zhai Fang Wang Jian Yang Bin Yang Caixia Cheng Jing Liu Bin Song Hongyi Li Yi Wang Yingchun Zhang Xiaolong Cheng Qimin Zhan Yanhong Li Zhihua Liu-Show 2020Cell Research2020,30,10:19
4Chronic intermittent hypoxia induces cardiac inflammation and dysfunction in a rat obstructive sleep apnea model显示文摘Chronic intermittent hypoxia is considered to play an important role in cardiovascular pathogenesis during the development of obstructive sleep apnea(OSA).We used a well-described OSA rat model induced with simultaneous intermittent hypoxia.Male Sprague Dawley rats were individually placed into plexiglass chambers with air pressure and components were electronically controlled.The rats were exposed to intermittent hypoxia 8 hours daily for 5weeks.The changes of cardiac structure and function were examined by ultrasound.The cardiac pathology,apoptosis,and fibrosis were analyzed by H&E staining,TUNNEL assay,and picosirius staining,respectively.The expression of inflammation and fibrosis marker genes was analyzed by quantitative real-time PCR and Western blot.Chronic intermittent hypoxia/low pressure resulted in significant increase of left ventricular internal diameters(LVIDs),endsystolic volume(ESV),end-diastolic volume(EDV),and blood lactate level and marked reduction in ejection fraction and fractional shortening.Chronic intermittent hypoxia increased TUNNEL-positive myocytes,disrupted normal arrangement of cardiac fibers,and increased Sirius stained collagen fibers.The expression levels of hypoxia induced factor(HIF)-l α,NF-κB,IL-6,and matrix metallopeptidase 2(MMP-2) were significantly increased in the heart of rats exposed to chronic intermittent hypoxia.In conclusion,the left ventricular function was adversely affected by chronic intermittent hypoxia,which is associated with increased expression of HIF-lα and NF-κB signaling molecules and development of cardiac inflammation,apoptosis and fibrosis.Qin Wei Yeping Bian Fuchao Yu Qiang Zhang Guanghao Zhang Yang Li Songsong Song Xiaomei Ren Jiayi Tong 2016The Journal of Biomedical Research2016,30,6:15
5Changes of Temperature and Precipitation Extremes in Hengduan Mountains,Qinghai-Tibet Plateau in 1961-2008显示文摘Variations and trends in extreme climate events are more sensitive to climate change than the mean values,and so have received much attention.In this study,twelve indices of temperature extremes and 11 indices of precipitation extremes at 32 meteorological stations in Hengduan Mountains were examined for the period 1961-2008.The results reveal statistically significant increases in the temperature of the warmest and coldest nights and in the frequencies of extreme warm days and nights.Decreases of the diurnal temperature range and the numbers of frost days and ice days are statistically significant.Regional averages of growing season length also display the trends consistent and significant with warming.At a large proportion of the stations,patterns of temperature extremes are consistent with warming since 1961:warming trends in minimum temperature indices are greater than those relating to maximum temperature.As the center of the Shaluli Mountain,the warming magnitudes decrease from inner to outer.Changes in precipitation extremes is low:trends are difficult to detect against the larger inter-annual and decadal-scale variability of precipitation,and only the wet day precipitation and the regional trend in consecutive dry days are significant at the 0.05 level.It can be concluded that the variation of extreme precipitation events is not obvious in the Hengduan Mountains,however,the regional trends generally decrease from the south to the north.Overall,the spatial distribution of temporal changes of all extreme climate indices in the Hengduan Mountains illustrated here reflects the climatic complexity in mountainous regions.NING Baoying YANG Xiaomei CHANG Li 2012Chinese Geographical Science2012,22,4:14

7Some Aspects of High Manganese Twinning-Induced Plasticity (TWIP) Steel, A Review显示文摘High manganese twinning-induced plasticity (TWIP) steel is a new kind of structural material and possesses both high strength and superior plasticity and can meet the weight-lightening requirement for manufacturing vehicle body. The excellent formability of the TWIP steel comes from the extraordinary strain hardening effect during plastic deformation. The reduction of specific weight by aluminum alloying and strain hardening effect can lead to an effective weight reduction of the steel components, and provide a better choice for materials in vehicle body design. The TWIP effect in high Mn steels is generally associated with the successive workhardening generated by twins and influenced by some factors, such as Mn content, Al addition revealed by stacking fault energy (SFE), grain size, deformation temperature and strain rate. The present review introduces some aspects of the TWIP steels relating to their physical metallurgy, influencing factors associated with their deformation mechanisms, and a prospect for the future investigation is also described. Moreover, as a potential candidate for replacing Ni-Cr austenitic stainless steel, researches on the oxidation behavior and corrosion resistance of Fe-Mn-Al-C system steels are also reviewed.Liqing CHEN Yang ZHAO Xiaomei QIN 2013Acta Metallurgica Sinica(English Letters)2013,26,1:11
8Sorption of tylosin and sulfamethazine on solid humic acid显示文摘Tylosin(TYL) and sulfamethazine(SMT) are ionizable and polar antimicrobial compounds,which have seeped into the environment in substantial amounts via fertilizing land with manure or sewage. Sorption of TYL and SMT onto humic acid(HA) may affect their environmental fate. In this study, the sorption of TYL and SMT on HA at different conditions(pH, ionic strength) was investigated. All sorption isotherms fitted well to the Henry and Freundlich models and they were highly nonlinear with values of n between 0.5 and 0.8, which suggested that the HA had high heterogeneity. The sorption of TYL and SMT on HA decreased with increasing p H(2.0–7.5), implying that the primary sorption mechanism could be due to cation exchange interactions between TYL^+/SMT^+ species and the functional groups of HA.Increasing ionic strength resulted in a considerable reduction in the K_d values of TYL and SMT,hinting that interactions between H bonds and π–π EDA might be an important factor in the sorption of TYL and SMT on HA. Results of Fourier transform infrared(FT-IR) and ~13C-nuclear magnetic resonance(NMR) analysis further demonstrated that carboxyl groups and O-alkyl structures in the HA could interact with TYL and SMT via ionic interactions and H bonds,respectively. Overall, this work gives new insights into the mechanisms of sorption of TYL and SMT on HA and hence aids us in assessing the environmental risk of TYL and SMT under diverse conditions.Xuetao Guo Bei Tu Jianhua Ge Chen Yang Xiaomei Song Zhi Dang 2016Journal of Environmental Sciences2016,28,5:9
9miR-188-5p regulates proliferation and invasion via PI3K/Akt/MMP-2/9 signaling in keloids显示文摘Keloids(KDs)and hypertrophic scars(HSs),two forms of pathological scars,seriously affect the physical and psychological health of patients.Despite many similarities with HSs,KDs are characterized by invasion and a high rate of recurrence after surgery,features they share in common with tumors.The underlying molecular mechanisms of this phenomenon have not been fully elucidated.In this study,we used microRNA(miRNA)array analysis to search for invasion-associated miRNAs in KDs.The expression of miR-188-5p in KDs,HSs,normal skin(NS)tissues,and cell lines was measured by quantitative real-time polymerase chain reaction.Furthermore,cell proliferation,migration,and invasion were detected in KD fibroblasts(KFs)and HS fibroblasts(HSFs),and interrelated proteins were ascertained by western blot analysis.It was found that miR-188-5p was significantly decreased in KD tissue compared with HS and NS tissues.Upregulated expression of miR-188-5p suppressed KF proliferation,migration,and invasion;and decreased expression of miR-188-5p also promoted HSF proliferation,migration,and invasion.The protein levels of MMP-2,MMP-9,PI3K,and p-Akt in miR-188-5p mimic-transfected KFs were repressed.In contrast,after transfection with miR-188-5p inhibitor,the protein levels of MMP-2,MMP-9,PI3K,and p-Akt were higher than the control in HSFs.Treatment with PI3K/Akt inhibitor LY294002 in KFs with miR-188-5p inhibitor did not further reduce their proliferation,migration,and invasion.The upregulation of MMP-2 and MMP-9 by miR-188-5p inhibitor could be abolished by LY294002.These findings together demonstrate a tumor-suppressive role of miR-188-5p in KD proliferation and invasion via PI3K/Akt/MMP-2/9 signaling,indicating that miR-188-5p may be a potential prognostic marker and therapeutic target for KDs.Wenyan Zhu Xiaoyan Wu Bo Yang Xiaodong Yao Xiaomei Cui Pan Xu Xiaodong Chen 2019Acta Biochimica et Biophysica Sinica2019,51,2:9
10Fractional Fourier domain hopped communication method based on chirp modulation for underwater acoustic channels显示文摘To improve the data rate of underwater acoustic frequency-hopped communications, frequency hopping is applied to different orders of fractional Fourier domain(Fr FD), to enable non-intrusive, bandwidth-limited acoustic communications.An Fr FD frequency-hopped communication method based on chirp modulation, namely multiple chirp shift keying-Fr FD hopping(MCSK-Fr FDH), is proposed for underwater acoustic channels. Validated by both simulations and experimental results, this method can reach a bandwidth efficiency twice more than conventional frequency-hopped methods with the same data rate and anti-multipath capability, suggesting that the proposed method achieves a better performance than the traditional frequencyhopped communication in underwater acoustic communication channels. Results also show that in practical scenarios, the MCSKFr FDH system with longer symbol length performs better at the low signal-to-noise ratio(SNR), while the system with larger frequency sweeping range performs better at a high SNR.Xingbin Tu Xiaomei Xu Zheguang Zou Liangliang Yang Jianming Wu 2017Journal of Systems Engineering and Electronics2017,28,3:9

12Basic theory and key technologies for marine geographic information system显示文摘Marine geographic information system (MGIS) has great ability to deal with the spatio-temporal problems and has potential superiority when it is applied to oceanography. Using the feature extraction of oceanic phenomena as a case study, the functions of the MGIS are analyzed, and thus the position of MGIS in the oceanography is defined. Comparing the requirement of MGIS with that of the traditional GIS which has been developed in the terrestrial applications in the past four decades, the frame for the functions of MGIS is constructed. According to the established MGIS, some key technologies are discussed in detail with emphasis on the specialities which can distinguish the MGIS from the traditional GIS.SU Fenzhen YANG Xiaomei XU Jun ZHANG Tianyu LUO Jiancheng 2006Acta Oceanologica Sinica2006,25,2:8
13Timing of transplantation of autologous bone marrow derived mesenchymal stem cells for treating myocardial infarction显示文摘It is still unclear whether the timing of intracoronary stem cell therapy affects the therapeutic response in patients with myocardial infarction.The natural course of healing the infarction and the presence of putative homing signals within the damaged myocardium appear to favor cell engraftment during the transendothelial passage in the early days after reperfusion.However,the adverse inflammatory environment,with its high oxidative stress,might be deleterious if cells are administered too early after reperfusion.Here we highlight several aspects of the timing of intracoronary stem cell therapy.Our results showed that transplantation of bone marrow mesenchymal stem cells at 2 4 weeks after myocardial infarction is more favorable for reduction of the scar area,inhibition of left ventricular remodeling,and recovery of heart function.Coronary injection of autologous bone marrow mesenchymal stem cells at 2 4 weeks after acute myocardial infarction is safe and does not increase the incidence of complications.CHEN YiHuan TENG XiaoMei CHEN WeiQian YANG JunJie YANG ZiYing YU YunSheng SHEN ZhenYa 2014Science China(Life Sciences)2014,57,2:7
14Alterations in gut microbiota and metabolites associated with altitude-induced cardiac hypertrophy in rats during hypobaric hypoxia challenge显示文摘The gut microbiota is involved in host responses to high altitude.However,the dynamics of intestinal microecology and their association with altitude-related illness are poorly understood.Here,we used a rat model of hypobaric hypoxia challenge to mimic plateau exposure and monitored the gut microbiome,short-chain fatty acids(SCFAs),and bile acids(BAs)over 28 d.We identified weight loss,polycythemia,and pathological cardiac hypertrophy in hypoxic rats,accompanied by a large compositional shift in the gut microbiota,which is mainly driven by the bacterial families of Prevotellaceae,Porphyromonadaceae,and Streptococcaceae.The aberrant gut microbiota was characterized by increased abundance of the Parabacteroides,Alistipes,and Lactococcus genera and a larger Bacteroides to Prevotella ratio.Trans-omics analyses showed that the gut microbiome was significantly correlated with the metabolic abnormalities of SCFAs and BAs in feces,suggesting an interaction network remodeling of the microbiome-metabolome after the hypobaric hypoxia challenge.Interestingly,the transplantation of fecal microbiota significantly increased the diversity of the gut microbiota,partially inhibited the increased abundance of the Bacteroides and Alistipes genera,restored the decrease of plasma propionate,and moderately ameliorated cardiac hypertrophy in hypoxic rats.Our results provide an insight into the longitudinal changes in intestinal microecology during the hypobaric hypoxia challenge.Abnormalities in the gut microbiota and microbial metabolites contribute to the development of high-altitude heart disease in rats.Zhiyuan Pan Yichen Hu Zongyu Huang Ni Han Yan Li Xiaomei Zhuang Jiye Yin Hui Peng Quansheng Gao Wenpeng Zhang Yong Huang Yujun Cui Yujing Bi Zhenjiang Zech Xu Ruifu Yang 2022Science China(Life Sciences)2022,65,10:5
15Progress in the development of techniques based on light scattering for single nanoparticle detection显示文摘Nanoparticles have recently attracted extensive attention in view of their great potential in biomedicine and bioanalytical ap- plications. Single particle detection via light scattering offers a simple and efficient approach for the size, size distribution, and concentration analysis of nanoparticles. In particular, intrinsic heterogeneity or rare events masked by ensemble averaging can be revealed. However, the sixth power dependence of Rayleigh scattering on particle size makes it very challenging to detect individual nanoparticles of small sizes. This article is intended to provide an overview of recent progress in the development of techniques based on light scattering for the detection of single nanoparticles.ZHU ShaoBin, WANG Shuo, YANG LingLing, HUANG TianXun & YAN XiaoMei Department of Chemical Biology, College of Chemistry and Chemical Engineering Key Laboratory for Chemical Biology of Fujian Province Key Laboratory of Analytical Science, Xiamen University, Xiamen 361005, China 2011Science China Chemistry2011,54,8:5
16Sulfonated carbon catalyzed oxidation of aldehydes to carboxylic acids by hydrogen peroxide显示文摘Sulfonated carbon as a strong and stable solid acid catalyst exhibited excellent catalytic performance in various acid-catalyzed reactions. Here, sulfonated carbon, as catalyst for oxidation reaction, was prepared via the carbonization of starch followed by sulfonation with concentrated sulfuric acid. N2 physisorption, X-ray diffraction, Fourier transform infrared spectroscopy, X-ray fluorescence and acid-base titration were used to characterize the obtained materials. The catalytic activity of sulfonated carbon was studied in the oxidation of aldehydes to carboxylic acids using 30 wt% H2O2 as oxidant. This oxidation protocol works well for various aldehydes including aromatic and aliphatic aldehydes. The sulfonated carbon can be recycled for three times without obvious loss of activity.Lipeng Zhou Beibei Dong Si Tang Hong Ma Chen Chen Jie Xu Xiaomei Yang Jie Xu 2013Journal of Energy Chemistry2013,22,4:4
17Aquaculture area extraction and vulnerability assessment in Sanduao based on richer convolutional features network model显示文摘Sanduao is an important sea-breeding bay in Fujian,South China and holds a high economic status in aquaculture.Quickly and accurately obtaining information including the distribution area,quantity,and aquaculture area is important for breeding area planning,production value estimation,ecological survey,and storm surge prevention.However,as the aquaculture area expands,the seawater background becomes increasingly complex and spectral characteristics differ dramatically,making it difficult to determine the aquaculture area.In this study,we used a high-resolution remote-sensing satellite GF-2 image to introduce a deep-learning Richer Convolutional Features(RCF)network model to extract the aquaculture area.Then we used the density of aquaculture as an assessment index to assess the vulnerability of aquaculture areas in Sanduao.The results demonstrate that this method does not require land and water separation of the area in advance,and good extraction can be achieved in the areas with more sediment and waves,with an extraction accuracy>93%,which is suitable for large-scale aquaculture area extraction.Vulnerability assessment results indicate that the density of aquaculture in the eastern part of Sanduao is considerably high,reaching a higher vulnerability level than other parts.LIU Yueming YANG Xiaomei WANG Zhihua LU Chen LI Zhi YANG Fengshuo 2019Journal of Oceanology and Limnology2019,37,6:4
18Indium doped CsPbI3 films for inorganic perovskite solar cells with efficiency exceeding 17%显示文摘In recent years,all-inorganic perovskite materials have set off a research boom owing to features,such as good thermal stability,suitable bandgap,and fascinating optical properties.However,the power conversion efficiency(PCE)and the ambient stability of all-inorganic perovskite solar cells still remain a challenge.Herein,we investigate the effect of the addition of InI3 into CsPbI3 film on the corresponding device.InI3 incorporation could retard the crystallization process and control the growth rate of CsPbI3 polycrystalline films,yielding a high quality film with large grains and few voids.The increment in electrostatic potential and the reduction of carrier recombination enabled the open-circuit voltage of fabricated perovskite solar cell to be increased from 0.89 to 0.99 V.The champion device delivered a power conversion efficiency of 17.09%,which is higher than 14.36%for the reference device.And the InI3-included solar cell without any encapsulation retained 77%of its original efficiency after 860 h aging at room temperature in N2 condition.Xiaomei Li Kaili Wang Femi Lgbari Chong Dong Wenfan Yang Chang Ma Heng Ma Zhao-Kui Wang Liang-Sheng Liao 2020Nano Research2020,13,8:4
19Evaluation of human epidermal growth factor receptor 2 status of breast cancer using preoperative multidetector computed tomography with deep learning and handcrafted radiomics features显示文摘Objective:To evaluate the human epidermal growth factor receptor 2(HER2)status in patients with breast cancer using multidetector computed tomography(MDCT)-based handcrafted and deep radiomics features.Methods:This retrospective study enrolled 339 female patients(primary cohort,n=177;validation cohort,n=162)with pathologically confirmed invasive breast cancer.Handcrafted and deep radiomics features were extracted from the MDCT images during the arterial phase.After the feature selection procedures,handcrafted and deep radiomics signatures and the combined model were built using multivariate logistic regression analysis.Performance was assessed by measures of discrimination,calibration,and clinical usefulness in the primary cohort and validated in the validation cohort.Results:The handcrafted radiomics signature had a discriminative ability with a C-index of 0.739[95%confidence interval(95%CI):0.661-0.818]in the primary cohort and 0.695(95%CI:0.609-0.781)in the validation cohort.The deep radiomics signature also had a discriminative ability with a C-index of 0.760(95%CI:0.690-0.831)in the primary cohort and 0.777(95%CI:0.696-0.857)in the validation cohort.The combined model,which incorporated both the handcrafted and deep radiomics signatures,showed good discriminative ability with a C-index of 0.829(95%CI:0.767-0.890)in the primary cohort and 0.809(95%CI:0.740-0.879)in the validation cohort.Conclusions:Handcrafted and deep radiomics features from MDCT images were associated with HER2 status in patients with breast cancer.Thus,these features could provide complementary aid for the radiological evaluation of HER2 status in breast cancer.Xiaojun Yang Lei Wu Ke Zhao Weitao Ye Weixiao Liu Yingyi Wang Jiao Li Hanxiao Li Xiaomei Huang Wen Zhang Yanqi Huang Xin Chen Su Yao Zaiyi Liu Changhong Liang 2020Chinese Journal of Cancer Research2020,32,2:4
20Targeting PFKL with penfluridol inhibits glycolysis and suppresses esophageal cancer tumorigenesis in an AMPK/FOXO3a/BIM-dependent manner显示文摘As one of the hallmarks of cancer,metabolic reprogramming leads to cancer progression,and targeting glycolytic enzymes could be useful strategies for cancer therapy.By screening a small molecule library consisting of 1320 FDA-approved drugs,we found that penfluridol,an antipsychotic drug used to treat schizophrenia,could inhibit glycolysis and induce apoptosis in esophageal squamous cell carcinoma(ESCC).Gene profiling and Ingenuity Pathway Analysis suggested the important role of AMPK in action mechanism of penfluridol.By using drug affinity responsive target stability(DARTS)technology and proteomics,we identified phosphofructokinase,liver type(PFKL),a key enzyme in glycolysis,as a direct target of penfluridol.Penfluridol could not exhibit its anticancer property in PFKL-deficient cancer cells,illustrating that PFKL is essential for the bioactivity of penfluridol.High PFKL expression is correlated with advanced stages and poor survival of ESCC patients,and silencing of PFKL significantly suppressed tumor growth.Mechanistically,direct binding of penfluridol and PFKL inhibits glucose consumption,lactate and ATP production,leads to nuclear translocation of FOXO3a and subsequent transcriptional activation of BIM in an AMPK-dependent manner.Taken together,PFKL is a potential prognostic biomarker and therapeutic target in ESCC,and penfluridol may be a new therapeutic option for management of this lethal disease.Cancan Zheng Xiaomei Yu Yiyao Liang Yidong Zhu Yan He Long Liao Dingkang Wang Yanming Yang Xingfeng Yin Ang Li Qingyu He Bin Li 2022Acta Pharmaceutica Sinica B2022,12,3:4
