| 1 | Chemical compound cinobufotalin potently induces FOXO1-stimulated cisplatin sensitivity by antagonizing its binding partner MYH9显示文摘In this study,we present novel molecular mechanisms by which FOXO1 functions as a tumor suppressor to prevent the pathogenesis of nasopharyngeal carcinoma(NPC).First,we observed that FOXO1 not only controlled tumor stemness and metastasis,but also sensitized NPC cells to cisplatin(DDP)in vitro and in vivo.Mechanistic studies demonstrated that FOXO1-induced miR-200b expression through the GSK3β/β-catenin/TCF4 network-mediated stimulation of ZEB1,which reduced tumor stemness and the epithelial–mesenchymal transition(EMT)signal.Furthermore,we observed FOXO1 interaction with MYH9 and suppression of MYH9 expression by modulating the PI3K/AKT/c-Myc/P53/miR-133a-3p pathway.Decreased MYH9 expression not only reduced its interactions with GSK3β,but also attenuated TRAF6 expression,which then decreased the ubiquitin-mediated degradation of GSK3βprotein.Increased GSK3βexpression stimulated theβ-catenin/TCF4/ZEB1/miR-200b network,which increased the downstream tumor stemness and EMT signals.Subsequently,we observed that chemically synthesized cinobufotalin(CB)strongly increased FOXO1-induced DDP chemosensitivity by reducing MYH9 expression,and the reduction in MYH9 modulated GSK3β/β-catenin and its downstream tumor stemness and EMT signal in NPC.In clinical samples,the combination of low FOXO1 expression and high MYH9 expression indicated the worst overall survival rates.Our studies demonstrated that CB potently induced FOXO1-mediated DDP sensitivity by antagonizing its binding partner MYH9 to modulate tumor stemness in NPC. | YongHao Li Xiong Liu Xian Lin Menyang Zhao Yanyi Xiao Chen Liu Zixi Liang Zelong Lin Renhui Yi Zibo Tang Jiahao Liu Xin Li Qingping Jiang Libo Li Yinyin Xie Zhen Liu Weiyi Fang | 2019 | Signal Transduction and Targeted Therapy2019，4，1： | 6 |

| 3 | ARRB2 promotes colorectal cancer growth through triggering WTAP显示文摘Colorectal cancer (CRC) is one of the most lethal cancers worldwide. The expression of β-arrestin2 (β-Arr2, ARRB2) in CRC has been well investigated;however, its exact mechanism causing the cancer progression remains unclear. In this study, we discovered that the expression level of ARRB2 was significantly upregulated in CRC as compared to the normal tissues by employing the Cancer Genome Atlas (TCGA) data, western blot analysis, and immunohistochemistry. Furthermore, the level of ARRB2 was correlated with the patients’ overall survival by Kaplan–Meier analysis. The higher expression of ARRB2 promoted CRC cell growth, enhanced the cell motility, and blocked cell apoptosis, which is crucial for tumor growth. Lastly, the suppression of ARRB2 expression was enough to attenuate the progression of CRC induced by azoxymethane/dextran sodium sulfate. Interestingly, we also found that the knockdown of ARRB2 decreased several cancer pathways mediated by the expression of Wilms tumor 1 associated protein (WTAP), which led to the inhibition of cell proliferation and migration. Altogether, our results demonstrated that ARRB2 promoted the growth and migration of CRC cells by regulating the WTAP expression. | Hongguang Liang Zelong Lin Youqiong Ye Rongcheng Luo Lixian Zeng | 2021 | Acta Biochimica et Biophysica Sinica2021，53，1： | 1 |
| 4 | Two alkynyl functionalized Co(Ⅱ)-MOFs as fluorescent sensors exhibiting selectivity and sensitivity for Fe3+ and nitroaromatic compounds显示文摘Two Co(II)-MOFs with different structures were successfully synthesized under the premise of designing two ligands containing alkynyl functional groups. Complexes 1 ([Co(TEPA)(TPT)2/3]·2DMF·H2O) and 2 ([Co(EPA)(TPT)]·1.5DMF·1.5H2O) show excellent luminescence properties. Meanwhile, as fluorescent sensors, complexes 1 and 2 exhibit selectivity and sensitivity for Fe3+ with the Ksv of 1.520 ×104 L/mol and 3.543 ×104 L/mol, which can rapidly detect nitroaromatic compounds in methanol and ethanol, especially for 2,4-NPH through fluorescence quenching with high quenching efficiency. In particular, the Ksv value of complexes 1 and 2 towards 2,4-NPH can reach up to 1.627 ×105 L/mol and 9.600 ×104 L/mol, demonstrating that complexes 1 and 2 are good candidates for the identification and detection of Fe3+and nitroaromatic compounds. | Yue Li Xia Wang Chengyong Xing Xiurong Zhang Zelong Liang Xiaokang Wang Kai Zhang Yutong Wang Di Liu Weidong Fan Fangna Dai | 2019 | Chinese Chemical Letters2019，30，7： | 0 |
| 5 | Dual-site lattice co-doping strategy regulated crystal-structure and microstructure for enhanced cycling stability of Co-free Ni-rich layered cathode显示文摘Affected by cobalt(Co)supply bottlenecks and high costs,Co-free Ni-rich layered cathodes are considered the most promising option for economical and sustainable development of lithium-ion batteries(LIBs).Low-cost LiNi_(x)Al_(1-x)O_(2)(x≥0.9)cathode are rarely reported due to their chemo-mechanical instabilities and poor cycle life.Herein,we employ a strategy of Mg/W Li/Ni dualsite co-doping LiNi_(0.9)Al_(0.1)O_(2)(named as LNA90)cathodes to enhance cycling stability by modifying the crystal structure and forming a center radially aligned microstructure.The Mg/W co-doped LiNi_(0.9)Al_(0.1)O_(2)cathode(named as LNAMW)exhibits high capacity retention of 94.9%at 1 C and 3.0-4.5 V after 100 cycles with 22.0%increase over the pristine cathode LNA90 and maintains the intact particle morphology.Meanwhile,the cycling performance of LNAMW cathode exceeds that of most reported Ni-rich cathodes(Ni mol%>80%).Our work offers a straightforward,efficient,and scalable strategy for the future design of Cofree Ni-rich cathodes to facilitate the development of economical lithium-ion batteries. | Lei Liu Yan Zhao Guanghui Jiang Liang Shan Zelong Yang Yaoqiang Ma Yingjie Zhang Qi Meng Peng Dong | 2023 | Nano Research2023，16，7： | 0 |
