| 1 | A novel intronic circular RNA,circGNG7,inhibits head and neck squamous cell carcinoma progression by blocking the phosphorylation of heat shock protein 27 at Ser78 and Ser82显示文摘Background:There is increasing evidence that circular RNAs(circRNAs)play a significant role in pathological processes including tumorigenesis.In contrast to exonic circRNAs,which are the most frequently reported circRNAs in cancer so far,the studies of intronic circRNAs have been greatly lagged behind.Here,we aimed to investigate the regulatory role of intronic circRNAs in head and neck squamous cell carcinoma(HNSCC).Methods:We conducted whole-transcriptome sequencing with four pairs of primary tumor tissues and adjacent normal tissues from HNSCC patients.Then,we characterized circGNG7 expression in HNSCC tissues and cell lines and explored its association with the prognosis of HNSCC patients.We also identified interactions between circGNG7 and functional proteins,which alter downstream signaling that regulate HNSCC progression.Results:In this study,we identified a new intronic circRNA,circGNG7,and validated its functional roles in HNSCC progression.CircGNG7 was predominately localized to the cytoplasm,and its expression was downregulated in both HNSCC tissues andCAL27,CAL33,SCC4,SCC9,HN6,and HN30 cells.Low expression of circGNG7 was significantly correlated with poor prognosis in HNSCC patients.Consistent with this finding,overexpression of circGNG7 strongly inhibited tumor cell proliferation,colony formation,in vitro migration,and in vivo tumor growth.Mechanistically,the expression of circGNG7 in HNSCC cells was regulated by the transcription factor SMAD family member 4(SMAD4).Importantly,we discovered that circGNG7 could bind to serine residues 78 and 82 of the functional heat shock protein 27(HSP27),occupying its phosphorylation sites and hindering its phosphorylation,which reduced HSP27-JNK/P38 mitogen-activated protein kinase(MAPK)oncogenic signaling.Downregulation of circGNG7 expression in HNSCC increased HSP27-JNK/P38 MAPK signaling and promoted tumor progression.Conclusions:Our results revealed that a new intronic circRNA,circGNG7,functions as a strong tumor suppressor and that circGNG7/HSP27-JNK/P38 MAPK signaling is a novel mechanism by which HNSCC progression can be controlled. | Houyu Ju Zhenrong Hu Dongliang Wei Jinyun Huang Xinyi Zhang Mengyu Rui Zhi Li Xiaomeng Zhang Jingzhou Hu Wei Guo Guoxin Ren | 2021 | Cancer Communications2021，41，11： | 4 |
| 2 | Facile preparation of core-shell Si@Li4Ti5O12 nanocomposite as large-capacity lithium-ion battery anode显示文摘As a promising alternative anode material,silicon(Si)presents a larger capacity than the commercial anode to achieve large capacity lithium-ion batteries.However,the application of pure Si as anode is hampered by limitations such as volume expansion,low conductivity and unstable solid electrolyte interphase.To break through these limitations,the core-shell Si@Li4Ti5O12nanocomposite,which was prepared via in-situ self-assembly reaction and decompressive boiling fast concentration method,was proposed in this work.This anode combines the advantages of nano-sized Si particle and pure Li4Ti5O12(LTO)coating layer,improving the performance of the lithium-ion batteries.The Si@Li4Ti5O12 anode displays a high initial discharge/charge specific capacity of 1756/1383 m Ahg^-1 at 500 mAg^-1(representing high initial coulombic efficiency of 78.8%),a large rate capability(specific capacity of 620 mAhg^-1 at4000 mAg^-1),an outstanding cycling stability(reversible specific capacity of 883 mAhg^-1 after 150 cycles)and a low volume expansion rate(only 3.3% after 150 cycles).Moreover,the synthesis process shows the merits of efficiency,simplicity,and economy,providing a reliable method to fabricate large capacity Si@Li4Ti5O12nanocomposite anode materials for practical lithium-ion batteries. | Mengjing Liu Hanyang Gao Guoxin Hu Kunxu Zhu Hao Huang | 2020 | Journal of Energy Chemistry2020，29，1： | 3 |
| 3 | Impact of diabetes on prognosis of gastric cancer patients performed with gastrectomy显示文摘Objective: This study aimed to determine the impact of type 2 diabetes mellitus(T2 DM) on clinical outcomes of gastric cancer(GC) patients and explore whether metformin use and good glycemic control could reverse it.Methods: Clinicopathologic data of consecutive GC patients who underwent gastrectomy at Nanfang Hospital between October 2004 and December 2015 were included. Propensity score matching(PSM) was performed to balance the important factors of the disease status between non-T2 DM and T2 DM group. The last follow-up time was January 2019.Results: A total of 1,692 eligible patients(1,621 non-T2 DM vs. 71 T2 DM) were included. After PSM, nonT2 DM group(n=139) and T2 DM group(n=71) were more balanced in baseline variables. The 5-year cancerspecific survival(CSS) rate in T2 DM group(47.0%) was inferior to that in non-T2 DM group(58.0%), but did not reach statistical significance [hazard ratio(HR)=1.319, 95% confidence interval(95% CI): 0.868-2.005, P=0.192].While the 5-year progress-free survival(PFS) rate of T2 DM group(40.6%) is significantly worse than that in nonT2 DM group(56.3%)(HR=1.516, 95% CI: 1.004-2.290, P=0.045). Univariate and multivariate analyses showed that T2 DM was an independent risk factor for PFS but not for CSS. In T2 DM group, metformin use subgroup was associated with superior 5-year CSS and PFS in compared with non-metformin use subgroup, although the difference was not statistically significant(5-year CSS: 48.0% vs. 45.4%, HR=0.680, 95% CI: 0.352-1.313,P=0.246;5-year PFS: 43.5% vs. 35.7%, HR=0.763, 95% CI: 0.400-1.454, P=0.406). The 5-year CSS rate was47.5% in good glycemic control subgroup and 44.1% in poor glycemic control subgroup(HR=0.826, 95% CI:0.398-1.713, P=0.605). And both two subgroups yielded a similar 5-year PFS rate(42.2% vs. 36.3%, HR=0.908,95% CI: 0.441-1.871, P=0.792).Conclusions: DM promoted disease progress of GC after gastrectomy but had not yet led to the significant discrepancy of CSS. For GC patients with T2 DM, metformin use was associated with superior survival but without statistical significance, while better glycemic control could not improve the prognosis. | Xinhua Chen Yuehong Chen Tao Li Luo Jun Tian Lin Yanfeng Hu Huilin Huang Hao Chen Hao Liu Tuanjie Li Guoxin Li Jiang Yu | 2020 | Chinese Journal of Cancer Research2020，32，5： | 2 |
| 4 | Insights into pH-dependent transformation of gibberellic acid in aqueous solution:Transformation pathway,mechanism and toxicity estimation显示文摘Gibberellic acid(GA_(3))is widely used in agriculture and maybe transfer with groundwater flow,which is an endocrine disruptor,but few studies have focused on the transformation pathway and toxicity assessment of GA_(3)and its products.Here,GA_(3)and its transformation products in aqueous solution were identified and quantified by liquid chromatography mass spectrometry hybrid ion trap time-of-flight(LCMS-IT-TOF)and high-performance liquid chromatography(HPLC),respectively.The results showed that the half-life of GA_(3)transformation in ultrapure water was 16.1–24.6 days at p H=2.0–8.0,with the lowest half-life occurring at p H=8.0 and highest half-life occurring at p H=3.3.Isomerized gibberellic acid(Iso-GA_(3))and gibberellenic acid(GEA)were the main transformation products with a little hydroxy gibberellic acid(OH-GA_(3)).In North China groundwater,the mass balance of GA_(3)and its products was 76.2%,including Iso-GA_(3)(58%),GEA(7.9%),GA_(3)(7.3%)and OH-GA_(3)(3%)after reaching transformation equilibrium.Using Gaussian 09 for chemical computation,it was found that the transformation mechanism of GA_(3)was dependent upon the bond energy and the stereochemical feature of its molecular structure.GA_(3)always isomerized from theγ-lactone ring due to the lowest bond energy between the oxygen terminus of theγ-lactone ring and A ring.While GA_(3)and its transformation products all had developmental toxicity,the predicated LC 50(96 hr)and LD 50 of the main products of GA_(3)were much lower than those of GA_(3),indicating GA_(3)would be transformed into higher toxicity derivatives in water environments,posing a significant health risk to humans and the environment. | Li Zhang Yajun Sun Zhimin Xu Wenjing Zhang Guoxin Huang Fei Liu Liang Chen | 2021 | Journal of Environmental Sciences2021，33，6： | 2 |
| 5 | Application and Development Prospect of Se-rich & High-Ca Organic Fertilizer显示文摘Se is one of trace elements necessary for the human body,and human body could absorb Se via the food. Se intake is insufficient in 2/3 region of China,which seriously affects health of local residents. Therefore,the research of Se-rich fertilizer and the development of Se-rich product become the research focus in food science,medicine and other fields. There are rich marine resources in Beibu Gulf waters of Guangxi,and much carapace organic waste is generated. These carapace waste not only has high Se content but also is composed of a lot of Ca. The preparation of Se-rich & high-Ca fertilizer by these carapace waste not only reaches the target of recycling and environment friendly but also increases the yield of agricultural products,reduces diseases and pests,improves quality,increases the added value of agricultural product,which brings better economic benefit and meets people's demand for healthy food. | Sha Guoxin Huang Wei Liu Yongxian Pan Liping Song Yan Zhang Yu Wang Daobo | 2018 | Meteorological and Environmental Research2018，9，3： | 2 |

| 12 | Diabetes mellitus promoted lymph node metastasis in gastric cancer: a 15-year single-institution experience显示文摘Background: Previous studies have revealed that diabetes mellitus (DM) promotes disease progress of gastric cancer (GC). This study aimed to further investigating whether DM advanced lymph nodes (LNs) metastasis in GC.Methods: The clinicopathologic data of GC patients with >15 examined LN (ELN) between October 2004 and December 2019 from a prospectively maintained database were included. The observational outcomes included the number (N3b status) and anatomical distribution (N3 stations) of metastatic LN (MLN).Results: A total of 2142 eligible patients were included in the study between October 2004 and December 2019. N3 stations metastasis (26.8% in DMvs. 19.3% in non-DM,P = 0.026) and N3b status (18.8% in DMvs. 12.8% in non-DM,P = 0.039) were more advanced in the DM group, and multivariate logistic regression analyses confirmed that DM was an independent factor of developing N3 stations metastasis (odds ratio [OR] = 1.771,P= 0.011) and N3b status (OR= 1.752,P= 0.028). Also, multivariate analyses determined DM was independently associated with more MLN (β = 1.424,P = 0.047). The preponderance of N3 stations metastasis (DMvs. non-DM, T1-2: 2.2%vs. 4.9%, T3: 29.0%vs. 20.3%, T4a: 38.9%vs. 25.8%, T4b: 50.0%vs. 36.6%;ELN16-29: 8.6%vs. 10.4%, ELN30-44: 27.9%vs. 20.5%, ELN ≥ 45: 37.7%vs. 25.3%), N3b status (DMvs. non-DM, T1-2: 0%vs. 1.7%, T3: 16.1%vs. 5.1%, T4a: 27.8%vs. 19.1%, T4b: 44.0%vs. 28.0%;ELN16-29: 8.6%vs. 7.9%, ELN30-44: 18.0%vs. 11.8%, ELN ≥ 45: 26.4%vs. 17.3%), and the number of MLN (DMvs. non-DM, T1-2: 0.4vs. 1.1, T3: 8.6vs. 5.2, T4a: 9.7vs. 8.6, T4b: 17.0vs. 12.8;ELN16-29: 3.6vs. 4.6, ELN30-44: 5.8vs. 5.5, ELN ≥ 45: 12.0vs. 7.7) of DM group increased with the advancement of primary tumor depth stage and raising of ELN.Conclusions: DM was an independent risk factor for promoting LN metastasis. The preponderance of LN involvement in the DM group was aggravated with the advancement of tumor depth. | Xinhua Chen Yuehong Chen Tao Li Weiqi Liang Huilin Huang Hongtao Su Chuyang Sui Yanfeng Hu Hao Chen Tian Lin Tao Chen Liying Zhao Hao Liu Guoxin Li Jiang Yu | 2022 | Chinese Medical Journal2022，，8： | 1 |

| 16 | RNAi screen to identify protein phosphatases that regulate the NF-kappaB signaling显示文摘NF-kappaB plays a critical role in cell survival,apoptosis,and inflammatory responses.Serine/threoninespecific phosphatases(PPs)represent the second major class of enzymes that catalyze the dephosphorylation of proteins.The roles of PPs regulating NF-kappaB activities are poorly understood.Here we describe an RNAi-based screen to identify the PPs that involve in regulating NFkappaB signaling.Thirty-four candidate PPs siRNAs were synthesized and primarily screened by NF-kappaB reporter gene assay in HeLa cells.PHLPP,one of the protein phosphatase type 2C family members(PP2C),was identified as a positive regulator of NF-kappaB signaling.Knock-down of PHLPP dramatically attenuated TNFα-stimulated NF-kappaB transcriptional activation.Knockdown of PHLPP led to enhancement of NF-kappaB/p65 nuclear import and retention,but decreased TNFα-induced phosphorylation at Ser276 on p65.This critical phosphorylation was also drastically reduced by knock-down of PKCalpha and Akt1,two important serine/threonine kinases dephosphorylated by PHLPP.The results together suggest that PHLPP-Akt-PKC may represent an important signaling loop that activates NF-kappaB/p65 signaling through critical serine phosphorylation. | Guoxin WANG Suping LI Feifei WANG Shufang HUANG Xian LI Wei XIONG Biliang ZHANG | 2010 | Frontiers in Biology2010，5，3： | 0 |
| 17 | TP53 polymorphisms are involved in inverse colorectal cancer comorbidity in Chinese schizophrenia patients显示文摘The inverse cancer comorbidity in schizophrenia patients may be related to the genetic factors,involving the regulation of apoptosis.The tumour suppressor gene TP53,involved in neural apoptosis,is one of the potential candidate genes associated with schizophrenia which might reduce colorectal cancer risk.We recruited 270 schizophrenia patients and 312 colorectal cancer patients without schizophrenia.To examine the genetic association between schizophrenia and colorectal cancer,we analysed eight SNPs(rs12951053,rs1625895,rs2909430,rs9895829,rs1042522,rs8079544,rs8064946,rs17806770)covering 14.35 kb in the region of TP53.We observed that one of the eight genetic polymorphisms showed statistically significant differences between the colorectal cancer subjects and the schizophrenia subjects(rs12951053,P=0.000 1,OR1.70,95%CI1.30-2.23).In addition,the haplotype of A-G(rs12951053-rs8064946),giving aglobal P=0.001 8,was the most significant.Our data indicate that the polymorphisms of rs12951053 in TP53confer reduced susceptibility to colorectal cancer and suggest a potential protective mechanism against colorectal cancer in the schizophrenia patients of Han Chinese origin. | Sun Liming Huang Guoxin Zhao Leyong Chen Xiaofen Chen Wenjiao | 2015 | 国际检验医学杂志2015，36，15： | 0 |
| 18 | Impact of preoperative therapy on surgical outcomes of laparoscopic total gastrectomy for gastric/gastroesophageal junction cancer显示文摘Objective: As laparoscopic surgery is widely applied for primarily treated gastric cancer(GC)/gastroesophageal junction cancer(GEJC) and gains many advantages, the feasibility of laparoscopic total gastrectomy(LTG) for GC/GEJC patients who have received preoperative therapy(PT) has come to the fore. This study aims to analyze the safety and feasibility of LTG after PT for GC/GEJC patients.Methods: We retrospectively analyzed the data of 511 patients with GC/GEJC undergoing LTG, of which 405received LTG(LTG group) and 106 received PT+LTG(PT-LTG group) at Nanfang Hospital between June 2018and September 2022. The surgical outcomes were compared between the two groups.Results: The surgical duration was significantly longer in the PT-LTG group(P<0.001), while the incidence of intraoperative complications(P=1.000), postoperative complications(LTG group vs. PT-LTG group: 26.2% vs.23.6%, P=0.587), the classification of complication severity(P=0.271), and postoperative recovery was similar between two groups. Notably, the incidence of anastomotic complications of esophagojejunostomy was also comparable between the two groups(LTG group vs. PT-LTG group: 5.9% vs. 5.7%, P=0.918). The univariate and multivariate analysis confirmed that positive proximal margin [positive vs. negative: odds ratio(OR)=14.094, 95%confidence interval(95% CI): 2.639-75.260, P=0.002], rather than PT, has an impact on anastomotic complications after LTG(OR=0.945, 95% CI: 0.371-2.408, P=0.905).Conclusions: PT did not increase the surgical risk of LTG for GC/GEJC. Therefore, considering the positive effect of PT on long-term survival, the broader application of PT and LTG for GC/GEJC is supported by our findings. | Yuehong Chen Zhijing Yang Mingli Zhao Chuanjin Xu Yuxuan Zhu Huimin Zhang Huilin Huang Yanmei Peng Yanfeng Hu Tian Lin Tao Chen Hao Chen Liying Zhao Hao Liu Guoxin Li Jiang Yu Xinhua Chen | 2023 | Chinese Journal of Cancer Research2023，35，4： | 0 |
| 19 | Status,Existing Problems and Countermeasures of Industrialization of Se-enriched Agriculture in Guangxi显示文摘With the rapid development of China's agricultural production and the improvement of people's living standards and health awareness,people's demands for food quality and nutrition have become increasingly strong.

| 20 | Intratumoral CD103+CD8+T cells predict response to neoadjuvant chemoimmunotherapy in advanced head and neck squamous cell carcinoma显示文摘Background Immune cell heterogenicity is known to determine the therapeutic response to cancer progression.Neoadjuvant chemoimmunotherapy(NACI)has shown clinical benefits in some patients with advanced head and neck squamous cell carcinoma(HNSCC),but the underlying mechanism behind this clinical response is unknown.The efficacy of NACI needs to be potentiated by identifying accurate biomarkers to predict clinical responses.Here,we attempted to identify molecules predicting NACI response in advanced HNSCC.Methods We performed combined single-cell RNA sequencing(scRNA-seq)and multiplex immunofluorescence(mIHC)staining with tumor samples derived from NACI-treated HNSCC patients to identify a new tumor-infiltrating cell(TIL)subtype,CD103+CD8+TILs,associated with clinical response,while both in vitro and in vivo assays were carried out to determine its antitumor efficiency.The regulatory mechanism of the CD103+CD8+TILs population was examined by performing cell-cell interaction analysis of the scRNA-seq data and spatial analysis of the mIHC images.Results We established intratumoral CD103+CD8+TILs density as a determinant of NACI efficacy in cancers.Our scRNA-seq results indicated that the population of CD103+CD8+TILs was dramatically increased in the responders of NACI-treated HNSCC patients,while mIHC analysis confirmed the correlation between intratumoral CD103+CD8+TILs density and NACI efficacy in HNSCC patients.Further receiver operating characteristic curve analysis defined this TIL subset as a potent marker to predict patient response to NACI.Functional assays showed that CD103+CD8+TILs were tumor-reactive T cells,while programmed cell death protein-1(PD-1)blockade enhanced CD103+CD8+TILs cytotoxicity against tumor growth in vivo.Mechanistically,targeting the triggering receptor expressed on myeloid cells 2-positive(TREM2+)macrophages might enhance the population of CD103+CD8+TILs and facilitate antitumor immunity during NACI treatment.Conclusions Our study highlights the impact of intratumoral CD103+CD8+TILs density on NACI efficacy in different cancers,while the efforts to elevate its population warrant further clinical investigation. | Siqi Ren Tianjun Lan Fan Wu Suling Chen Xue Jiang Chuying Huo Zitian Li Shule Xie Donghui Wu Ruixin Wang Yanyan Li Lin Qiu Guoxin Huang Shurui Li Xiaojuan Wang Meifeng Cen Tingting Cai Zhaoyu Lin Jinsong Li Bowen Li | 2023 | Cancer Communications2023，43，10： | 0 |
