| 1 | Isotoosendanin exerts inhibition on triple-negative breast cancer through abrogating TGF-β-induced epithelial—mesenchymal transition via directly targeting TGFβR1显示文摘As the most aggressive breast cancer,triple-negative breast cancer(TNBC) is still incurable and very prone to metastasis.The transform growth factor β(TGF-β)-induced epithelial—mesenchymal transition(EMT) is crucially involved in the growth and metastasis of TNBC.This study reported that a natural compound isotoosendanin(ITSN) reduced TNBC metastasis by inhibiting TGF-β-induced EMT and the formation of invadopodia.ITSN can directly interact with TGF-β receptor type-1(TGFβR1) and abrogated the kinase activity of TGFβR1,thereby blocking the TGF-β-initiated downstream signaling pathway.Moreover,the ITSN-provided inhibition on metastasis obviously disappeared in TGFβR1-overexpressed TNBC cells in vitro as well as in mice bearing TNBC cells overexpressed TGFβR1.Furthermore,Lys232 and Asp351 residues in the kinase domain of TGFβR1 were found to be crucial for the interaction of ITSN with TGFβR1.Additionally,ITSN also improved the inhibitory efficacy of programmed cell death 1 ligand 1(PD-L1) antibody for TNBC in vivo via inhibiting the TGF-β-mediated EMT in the tumor microenvironment.Our findings not only highlight the key role of TGFβR1 in TNBC metastasis,but also provide a leading compound targeting TGFβR1 for the treatment of TNBC metastasis.Moreover,this study also points out a potential strategy for TNBC treatment by using the combined application of anti-PD-L1 with a TGFβR1 inhibitor. | Jingnan Zhang Ze Zhang Zhenlin Huang Manlin Li Fan Yang Zeqi Wu Qian Guo Xiyu Mei Bin Lu Changhong Wang Zhengtao Wang Lili Ji | 2023 | Acta Pharmaceutica Sinica B2023，13，7： | 1 |
| 2 | Heat treatment of hot-isostatic-pressed 60NiTi shape memory alloy:Microstructure,phase transformation and mechanical properties显示文摘60NiTi alloy is considered to be a promising material for specialized bearing and gear applications due to its high hardness,strength,and low modulus.However,fabricating 60NiTi through conventional processing methods is challenging due to the brittleness and poor workability.In this study,60NiTi with high relative density was successfully fabricated directly from pre-alloyed powder through hot isostatic pressing.The effects of solution and aging treatments on microstructure and mechanical properties were systematically studied by advanced characterization techniques.The hot-isostatic-pressed 60NiTi showed low average hardness and elastic strain due to the formation of a soft Ni_(3)Ti phase and B2 NiTi matrix.Solution treatment above 1000℃dissolved the Ni_(3)Ti phase and promoted the formation of nanoscale Ni_(4)Ti_(3)precipitates,which significantly improved the hardness,strength,and elastic strain of 60NiTi.The formation of the Ni_(4)Ti_(3) phase can be mainly attributed to the driving forces induced by the chemical supersaturation and mechanical stress concentration.Finally,the phase transformation mechanisms during heat treatment and compression test were discussed. | Yinghao Zhou Xiyu Yao Wenfei Lu Dandan Liang Xiaodi Liu Ming Yan Jun Shen | 2022 | Journal of Materials Science & Technology2022，，12： | 1 |
| 3 | Recent advancements of photo-and electro-active hydrogenbonded organic frameworks显示文摘The development of hydrogen-bonded organic frameworks(HOFs) with predictable topologies and robust structures for targeted functionality was initially hindered by the relatively weak H-bonding interactions as many HOFs would collapse upon guest solvent removal. Recently, the design of tectons with large π-conjugated systems that form intermolecular shape-fitted π-πstacking interactions has proven to be an effective strategy to create chemically and thermally stable HOFs. More importantly,these HOFs with large π-conjugated tectons exhibit accelerated redox hopping processes due to more favorable through-space orbital overlap interactions. These intrinsic photoelectric properties render HOFs an appealing and unique class of photoactive and electroactive porous materials for catalysis, sensing, and biomedical applications. Based on shape-fitted π-π stacking strategy, various robust photoactive and electroactive HOFs have been built from tectons containing both photosensitive or redox-active organic cores and hydrogen bonding sites. This review summarizes the recent advancements, including synthetic methods and diverse applications, in the development of photo-and electro-active HOFs. Considering the numerous photo-and electro-active organic units available, as well as the virtually unlimited potential combinations of organic cores and hydrogen bonding sites, we anticipate that this review will inspire scientists in a range of disciplines, ranging from porous materials to organic photoelectric materials and catalysis scientists, to further explore functional photo-and electro-active HOF materials. | Xiangyu Gao Wanyue Lu Yao Wang Xiyu Song Cheng Wang Kent O.Kirlikovali Peng Li | 2022 | Science China Chemistry2022，65，11： | 0 |
| 4 | Generation ofαGal-enhanced bifunctional tumor vaccine显示文摘Hepatocellular carcinoma(HCC)is a common malignant tumor with poor prognosis and high mortality.In this study,we demonstrated a novel vaccine targeting HCC and tumor neovascular endothelial cells by fusing recombinant MHCC97H cells expressing porcine a-1,3-galactose epitopes(a Gal)and endorphin extracellular domains(END)with dendritic cells(DCs)from healthy volunteers.END^(+)/Gal^(+)-MHCC97H/DC fusion cells induced cytotoxic T lymphocytes(CTLs)and secretion of interferon-gamma(IFN-γ).CTLs targeted cells expressing a Gal and END and tumor angiogenesis.The fused cell vaccine can effectively inhibit tumor growth and prolong the survival time of human hepatoma mice,indicating the high clinical potential of this new cell based vaccine. | Jian He Yu Huo Zhikun Zhang Yiqun Luo Xiuli Liu Qiaoying Chen Pan Wu Wei Shi Tao Wu Chao Tang Huixue Wang Lan Li Xiyu Liu Yong Huang Yongxiang Zhao Lu Gan Bing Wang Liping Zhong | 2022 | Acta Pharmaceutica Sinica B2022，12，7： | 0 |
| 5 | Generation of in situ CRISPR-mediated primary and metastatic cancer from monkey liver显示文摘Non-human primates(NHPs)represent the most valuable animals for drug discovery.However,the current main challenge remains that the NHP has not yet been used to develop an efficient translational medicine platform simulating human diseases,such as cancer.This study gen erated an in situ gen e-editi ng approach to in duce efficie nt loss-of-function mutations of Pten and p53 genes for rapid modeling primary and metastatic liver tumors using the CRISPR/Cas9 in the adult cyno molgus mon key.Un der ultraso und guida nee,the CRISPR/Cas9 was injected into the cyno molgus mon key liver through the in trahepatic portal vein.The results showed that the ultraso un d-guided CRISPR/Cas9 resulted in in dels of the Pten and p53 genes in seve n out of eight monkeys.The best mutation efficiencies for Pten and p53 were up to 74.71%and 74.68%,respectively.Furthermore,the morbidity of primary and exte nsively metastatic(lung,splee n,lymph nodes)hepatoma in CRISPR-treated mon keys was 87.5%.The ultraso un d-guided CRISPR system could have great potential to successfully pursue the desired target genes,thereby reducing possible side effects associated with hitting no n-specific off-target genes,and sign ifica ntly in creasing more efficie ncy as well as higher specificity of in situ gene editi ng in vivo,which holds promise as a powerful,yet feasible tool,to edit disease genes to build corresp on ding huma n disease models in adult NHPs and to greatly accelerate the discovery of new drugs and save economic costs. | Liping Zhong Yong Huang Jian He Nuo Yang Banghao Xu Yun Ma Junjie Liu Chao Tang Chengpiao Luo Pan Wu Zongqiang Lai Yu Huo Tao Lu Dongni Huang Wenlin Gong Lu Gan Yiqun Luo Zhikun Zhang Xiyu Liu Yongxiang Zhao | 2022 | Signal Transduction and Targeted Therapy2022，7，1： | 0 |

| 7 | Dual-mode distributed feedback quantum cascade laser based on stacked 3D monolithic integration for on-chip multi-channel gas sensing显示文摘To facilitate the development of on-chip integrated mid-infrared multi-channel gas sensing systems,we propose a high-power dual-mode(7.01 and 7.5μm)distributed feedback quantum cascade laser based on stacked 3D monolithic integration.Longitudinal mode control is achieved by preparing longitudinal nested bi-periodic compound one-dimensional Bragg gratings along the direction of the cavity length in the confinement layer.Additionally,transverse coherent coupling ridges perpendicular to the cavity length direction are fabricated in the upper waveguide layer to promote the fundamental transverse mode output when all ridges are in phase.Stable dual-wavelength simultaneous emission with a side-mode suppression ratio of more than 20 dB was achieved by holographic exposure and wet etching.The entire spectral tuning range covers nearly 100 nm through joint tuning of the injection current and heat-sink temperature.High peak power and beam quality are guaranteed by the parallel coherent integration of seven-element ridge arrays.The device operates in a fundamental supermode with a single-lobed far-field pattern,and its peak output power reaches 3.36 W in pulsed mode at 20℃.This dual-mode laser chip has the potential for in-situ on-chip simultaneous detection of CH4and C2H6gases in leak monitoring. | XIYU LU YANJIAO GUAN PENGCHANG YANG SHAN NIU YU MA LIJUN WANG NING ZHUO JINCHUAN ZHANG SHENQIANG ZHAI FENGMIN CHENG SHUMAN LIU FENGQI LIU JUNQI LIU | 2023 | Photonics Research2023，11，12： | 0 |
| 8 | Diabetes: An Accomplice to Cancer显示文摘Worldwide, cancer and diabetes are two major chronic diseases that have great impacts on human health. Clinical and basic research studies have shown that diabetes, especially type 2 diabetes mellitus (T2DM), can promote the incidence and development of colon, pancreatic, breast, liver and bladder cancers. Hyperglycemia, chronic inflammation and abnormal metabolism are considered to be major risk factors involved in the development of cancer. Notably, some treatments used for diabetes, such as maintenance of a healthy diet and the use of hypoglycemic drugs to control blood glucose levels, may decrease the risk of cancer. On the other hand, metabolic disorders and the organ damage caused by cancer can also promote or accelerate the progression of diabetes. By reviewing the relevant literature, we found that diabetes can promote the occurrence and development of some cancers, and cancer can, in turn, influence diabetes. We herein discuss and summarize the mechanisms underlying the relationship between diabetes and cancer and the new therapeutic strategies based on this relationship. | Ting WenGe You XiYu Lu Cai Jiu WeiCui | 2019 | Journal of Nutritional Oncology2019，4，1： | 0 |
| 9 | Small molecule donors with different conjugated π linking bridges: Synthesis and photovoltaic properties显示文摘Three small molecule(SM)donors,namely B-T-CN,B-TT-CN and B-DTT-CN,with differentπconjugated bridges were synthesized in this research.Interestingly,with the conjugated fused rings of theπlinking bridge increasing,the SM HOMO levels exhibit a decline tendency with–5.27 eV for B-T-CN,–5.31 eV for B-TT-CN and–5.40 eV for B-DTT-CN.After blending the SM donors with the fullerene acceptor PC71BM,the all SM organic solar cells(OSCs)achieved high Vocs of 0.90 to 0.96 V.However,the phase separation morphology and molecule stacking are also unexpectedly changed together with the enhancement of conjugated degree ofπbridges,resulting in a lower power conversion efficiency(PCE)for the B-DTT-CN:PC71BM device.Our results demonstrate and provide a useful way to enhance OSC Voc and the morphology needs to be further optimized. | Xiyue Dong Dingqin Hu Pengyu Chen Xuexin Dai Chao Hu Zeyun Xiao Shirong Lu | 2020 | Journal of Semiconductors2020，41，12： | 0 |
| 10 | Biomaterials and tissue engineering in traumatic brain injury:novel perspectives on promoting neural regeneration显示文摘Traumatic brain injury is a serious medical condition that can be attributed to falls, motor vehicle accidents, sports injuries and acts of violence, causing a series of neural injuries and neuropsychiatric symptoms. However, limited accessibility to the injury sites, complicated histological and anatomical structure, intricate cellular and extracellular milieu, lack of regenerative capacity in the native cells, vast variety of damage routes, and the insufficient time available for treatment have restricted the widespread application of several therapeutic methods in cases of central nervous system injury. Tissue engineering and regenerative medicine have emerged as innovative approaches in the field of nerve regeneration. By combining biomaterials, stem cells, and growth factors, these approaches have provided a platform for developing effective treatments for neural injuries, which can offer the potential to restore neural function, improve patient outcomes, and reduce the need for drugs and invasive surgical procedures. Biomaterials have shown advantages in promoting neural development, inhibiting glial scar formation, and providing a suitable biomimetic neural microenvironment, which makes their application promising in the field of neural regeneration. For instance, bioactive scaffolds loaded with stem cells can provide a biocompatible and biodegradable milieu. Furthermore, stem cells-derived exosomes combine the advantages of stem cells, avoid the risk of immune rejection, cooperate with biomaterials to enhance their biological functions, and exert stable functions, thereby inducing angiogenesis and neural regeneration in patients with traumatic brain injury and promoting the recovery of brain function. Unfortunately, biomaterials have shown positive effects in the laboratory, but when similar materials are used in clinical studies of human central nervous system regeneration, their efficacy is unsatisfactory. Here, we review the characteristics and properties of various bioactive materials, followed by the introduction of applications based on biochemistry and cell molecules, and discuss the emerging role of biomaterials in promoting neural regeneration. Further, we summarize the adaptive biomaterials infused with exosomes produced from stem cells and stem cells themselves for the treatment of traumatic brain injury. Finally, we present the main limitations of biomaterials for the treatment of traumatic brain injury and offer insights into their future potential. | Shihong Zhu Xiaoyin Liu Xiyue Lu Qiang Liao Huiyang Luo Yuan Tian Xu Cheng Yaxin Jiang Guangdi Liu Jing Chen | 2024 | Neural Regeneration Research2024，19，10： | 0 |
| 11 | Hepatic DDAH1 mitigates hepatic steatosis and insulin resistance in obese mice: Involvement of reduced S100A11 expression显示文摘Dimethylarginine dimethylaminohydrolase 1(DDAH1)is an important regulator of plasma asymmetric dimethylarginine(ADMA)levels,which are associated with insulin resistance in patients with nonalcoholic fatty liver disease(NAFLD).To elucidate the role of hepatic DDAH1 in the pathogenesis of NAFLD,we used hepatocyte-specific Ddah1-knockout mice(Ddah1HKO)to examine the progress of high-fat diet(HFD)-induced NAFLD.Compared to diet-matched flox/flox littermates(Ddah1f/f),Ddah1HKO mice exhibited higher serum ADMA levels.After HFD feeding for 16 weeks,Ddah1HKO mice developed more severe liver steatosis and worse insulin resistance than Ddah1f/f mice.On the contrary,overexpression of DDAH1 attenuated the NAFLD-like phenotype in HFD-fed mice and ob/ob mice.RNA-seq analysis showed that DDAH1 affects NF-kB signaling,lipid metabolic processes,and immune system processes in fatty livers.Furthermore,DDAH1 reduces S100 calcium-binding protein A11(S100A11)possibly via NF-kB,JNK and oxidative stress-dependent manner in fatty livers.Knockdown of hepatic S100a11 by an AAV8-shS100a11 vector alleviated hepatic steatosis and insulin resistance in HFD-fed Ddah1HKO mice.In summary,our results suggested that the liver DDAH1/S100A11 axis has a marked effect on liver lipid metabolism in obese mice.Strategies to increase liver DDAH1 activity or decrease S100A11 expression could be a valuable approach for NAFLD therapy. | Xiyue Shen Kai Luo Juntao Yuan Junling Gao Bingqing Cui Zhuoran Yu Zhongbing Lu | 2023 | Acta Pharmaceutica Sinica B2023，13，8： | 0 |
| 12 | Milankovitch theory and monsoon显示文摘The widely accepted“Milankovitch theory”explains insolation-induced waxing and waning of the ice sheets and their effect on the global climate on orbital timescales.In the past half century,however,the theory has often come under scrutiny,especially regarding its“100-ka problem.”Another drawback,but the one that has received less attention,is the“monsoon problem,”which pertains to the exclusion of monsoon dynamics in classic Milankovitch theory even though the monsoon prevails over the vast low-latitude(30N to30S)region that covers half of the Earth’s surface and receives the bulk of solar radiation.In this review,we discuss the major issues with the current form of Milankovitch theory and the progress made at the research forefront. | Hai Cheng Hanying Li Lijuan Sha Ashish Sinha Zhengguo Shi Qiuzhen Yin Zhengyao Lu Debo Zhao Yanjun Cai Yongyun Hu Qingzhen Hao Jun Tian Gayatri Kathayat Xiyu Dong Jingyao Zhao Haiwei Zhang | 2022 | The Innovation2022，3，6： | 0 |
