| 2 | A targetable pathway to eliminate TRA-1-60^(+)/TRA-1-81^(+)chemoresistant cancer cells显示文摘Chemoresistance is a primary cause of treatment failure in pancreatic cancer.Identifying cell surface markers specifically expressed in chemoresistant cancer cells(CCCs)could facilitate targeted therapies to overcome chemoresistance.We performed an antibody-based screen and found that TRA-1-60 and TRA-1-81,two‘stemness’cell surface markers,are highly enriched in CCCs.Further-more,TRA-1-60^(+)/TRA-1-81^(+)cells are chemoresistant compared to TRA-1-60^(-)/TRA-1-81^(-)cells.Transcriptome profiling identified UGT1A10,shown to be both necessary and sufficient to maintain TRA-1-60/TRA-1-81 expression and chemoresistance.From a high-content chemical screen,we identified Cymarin,which downregulates UGT1A10,eliminates TRA-1-60/TRA-1-81 expression,and increases chemosensitivity both in vitro and in vivo.Finally,TRA-1-60/TRA-1-81 expression is highly specific in primary cancer tissue and positively correlated with chemoresistance and short survival,which highlights their potentiality for targeted therapy.Therefore,we discovered a novel CCC surface marker regulated by a pathway that promotes chemoresistance,as well as a leading drug candidate to target this pathway. | Lei Tan Xiaohua Duan Pratyusha Mutyala Ting Zhou Sadaf Amin Tuo Zhang Brian Herbst Gokce Askan Tomer Itkin Zhaoying Xiang Fabrizio Michelassi Michael D.Lieberman Christine AIacobuzio-Donahue Steven DLeach Todd Evans Shuibing Chen | 2023 | Journal of Molecular Cell Biology2023，15，6： | 0 |

| 4 | 3D forward modeling and response characteristics of low-resistivity overburden of the CFS-PML absorbing boundary for ground-well transient electromagnetic method显示文摘This study used the stable and convergent Dufort-Frankel method to differentially discretize the diffusion equation of the ground-well transient electromagnetic secondary field.The absorption boundary condition of complex frequency-shifted perfectly matched layer(CFS-PML)was used for truncation so that the low-frequency electromagnetic wave can be better absorbed at the model boundary.A typical three-dimensional(3D)homogeneous half-space model was established and a low-resistivity cube model was analyzed under the half-space condition.The response patterns and drivers of the low-resistivity cube model were discussed under the influence of a low-resistivity overburden.The absorption boundary conditions of CFS-PML significantly affected the low-frequency electromagnetic waves.For a low-resistivity cube around the borehole,its response curve exhibited a single-peak,and the extreme point of the curve corresponded to the center of the low-resistivity body.When the low-resistivity cube was directly below the borehole,the response curve showed three extreme values(two high and one low),with the low corresponding to the center of the low-resistivity body.The total field response of the low-resistivity overburden was stronger than that of the uniform half-space model due to the low-resistivity shielding effect of electromagnetic waves.When the receiving-transmitting distance gradually increased,the effect of the low-resistivity overburden was gradually weakened,and the response of the low-resistivity cube was strengthened.It was affected by the ratio of the overburden resistivity to the resistivity of the low-resistivity body. | Lijuan Zhao Mingzhong Gao Nengzhong Lei Hongfei Duan Weizhong Qiu Zhaoying Chen | 2023 | International Journal of Mining Science and Technology2023，33，12： | 0 |
| 5 | AIFM1 variants associated with auditory neuropathy spectrum disorder cause apoptosis due to impaired apoptosis-inducing factor dimerization显示文摘Auditory neuropathy spectrum disorder(ANSD)represents a variety of sensorineural deafness conditions characterized by abnormal inner hair cells and/or auditory nerve function,but with the preservation of outer hair cell function.ANSD represents up to 15%of individuals with hearing impairments.Through mutation screening,bioinformatic analysis and expression studies,we have previously identified several apoptosis-inducing factor(AIF)mitochondria-associated 1(AIFM1)variants in ANSD families and in some other sporadic cases.Here,to elucidate the pathogenic mechanisms underlying each AIFM1 variant,we generated AIF-null cells using the clustered regularly interspersed short palindromic repeats(CRISPR)/CRISPR-associated protein 9(Cas9)system and constructed AIF-wild type(WT)and AIF-mutant(mut)(p.T260A,p.R422W,and p.R451Q)stable transfection cell lines.We then analyzed AIF structure,coenzyme-binding affinity,apoptosis,and other aspects.Results revealed that these variants resulted in impaired dimerization,compromising AIF function.The reduction reaction of AIF variants had proceeded slower than that of AIF-WT.The average levels of AIF dimerization in AIF variant cells were only 34.5%-49.7%of that of AIF-WT cells,resulting in caspase-independent apoptosis.The average percentage of apoptotic cells in the variants was 12.3%-17.9%,which was significantly higher than that(6.9%-7.4%)in controls.However,nicotinamide adenine dinucleotide(NADH)treatment promoted the reduction of apoptosis by rescuing AIF dimerization in AIF variant cells.Our findings show that the impairment of AIF dimerization by AIFM1 variants causes apoptosis contributing to ANSD,and introduce NADH as a potential drug for ANSD treatment.Our results help elucidate the mechanisms of ANSD and may lead to the provision of novel therapies. | YUE QIU HONGYANG WANG HUAYE PAN JING GUAN LEI YAN MINGJIE FAN HUI ZHOU XUANHAO ZHOU KAIWEN WU ZEXIAO JIA QIANQIAN ZHUANG ZHAOYING LEI MENGYAO LI XUE DING AIFU LIN YONG FU DONG ZHANG QIUJU WANG QINGFENG YAN | 2023 | Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2023，24，2： | 0 |
