1Paired related homeobox 1 transactivates dopamine D2 receptor to maintain propagation and tumorigenicity of glioma-initiating cells显示文摘Glioblastoma multiforme (GBM ) 是有有限治疗学的工具和差的预后的一个高度侵略的大脑肿瘤。最近的研究显示开始 glioma cells/glioma 干细胞(GICs/GSCs ) 可能为肿瘤开始,渗入,和复发负责。GIC 能异常地采用平衡胚胎的神经先锋的自强和区别的分子的机械。这里,我们发现那配对的相关 homeobox 1 (PRRX1 ) ,以前是的一个 homeodomain 抄写因素报导了控制骨胳的开发,在外皮的神经祖先被表示并且为他们的自强和合适的区别被要求。进一步, PRRX1 是在 glioma 样品和标签 GIC 的 overrepresented。Glioma 房间和 GIC 与 PRRX1 弄空不能在 vitro 宣传或在异种皮移植老鼠模型形成肿瘤。PRRX1 调整的 GIC 自强功能被多巴胺 D2 受体(DRD2 ) 调停。PRRX1 直接在 GIC 把它的表示绑在 DRD2 倡导者和 transactivates。发信号的 DRD2 的阻塞妨碍 GIC 自强,而它的 overexpression 恢复宣传和弄空 PRRX1 的 GIC 的 tumorigenic 潜力。最后, PRRX1 加强经由调停 DRD2 的细胞外的信号相关的 kinase (英皇家空军之阶级最低之兵) 和 AKT 的 GIC 激活。因此,我们的学习建议那治疗学的指向在 GIC 的 PRRX1DRD2ERK/AKT 轴是为对待 GBM 的有希望的策略。Yamu Li Wen Wang Fangyu Wang Qiushuang Wu Wei Li Xiaoling Zhong Kuan Tian Tao Zeng Liang Gao Ying Liu Shu Li Xiaobing Jiang Guangwei Du Yan Zhou 2017Journal of Molecular Cell Biology2017,9,4:5
2Long non-coding RNA LncKdm2b regulates cortical neuronal differentiation by cis-activating Kdm2b显示文摘The mechanisms underlying spatial and temporal control of cortical neurogenesis of the brain are largely elusive.Long non-coding RNAs(lncRNAs)have emerged as essential cell fate regulators.Here we found LncKdm2b(also known as Kancr),a lncRNA divergently transcribed from a bidirectional promoter of Kdm2b,is transiently expressed during early differentiation of cortical projection neurons.Interestingly,Kdm2b’s transcription is positively regulated in cis by LncKdm2b,which has intrinsic-activating function and facilitates a permissive chromatin environment at the Kdm2b’s promoter by associating with hnRNPAB.Lineage tracing experiments and phenotypic analyses indicated LncKdm2b and Kdm2b are crucial in proper differentiation and migration of cortical projection neurons.These observations unveiled a lncRNA-dependent machinery in regulating cortical neuronal differentiation.Wei Li Wenchen Shen Bo Zhang Kuan Tian Yamu Li Lili Mu Zhiyuan Luo Xiaoling Zhong Xudong Wu Ying Liu Yan Zhou 2020Protein & Cell2020,11,3:2
3PD-L1 expression is regulated by ATP-binding of the ERBB3 pseudokinase domain显示文摘How PD-L1 expression is regulated in cancer is poorly understood.Here,we report that the ATP-binding activity of ERBB3 pseudokinase regulates PD-L1 gene expression in colorectal cancers(CRCs).ERBB3 is one of the four members of the EGF receptor family,all with protein tyrosine kinase domains.ERBB3 is a pseudokinase with a high binding affin-ity to ATP.We showed that ERBB3 ATP-binding inactivation mutant reduces tumorigenicity in genetically engineered mouse models and impairs xenograft tumor growth of CRC cell lines.The ERBB3 ATP-binding mutant cells dramatically reduce IFN-g-induced PD-L1 expres-sion.Mechanistically,ERBB3 regulates IFN-g-induced PD-L1 expression through the IRS1-PI3K-PDK1-RSK-CREB signaling axis.CREB is the transcription factor that regulates PD-L1 gene expression in CRC cells.Knockin of a tumor-derived ERBB3 mutation located in the ki-nase domain sensitizes mouse colon cancers to anti-PD1 antibody therapy,suggesting that ERBB3 mutations could be predictive biomarkers for tumors amenable to immune check-point therapy.Yamu Li Zhonghua Liu Yiqing Zhao Jie Yang Tsan Sam Xiao Ronald A.Conlon Zhenghe Wang 2023Genes & Diseases2023,10,4:0
4Transcriptome Analysis Identifies SenZfp536,a Sense LncRNA that Suppresses Self-renewal of Cortical Neural Progenitors显示文摘Long non-coding RNAs(lncRNAs)regulate transcription to control development and homeostasis in a variety of tissues and organs.However,their roles in the development of the cerebral cortex have not been well elucidated.Here,a bioinformatics pipeline was applied to delineate the dynamic expression and potential cis-regulating effects of mouse lncRNAs using transcriptome data from 8 embryonic time points and sub-regions of the developing cerebral cortex.We further characterized a sense lncRNA,SenZfp536,which is transcribed downstream of and partially overlaps with the protein-coding gene Zfp536.Both SenZfp536 and Zfp536 were predominantly expressed in the proliferative zone of the developing cortex.Zfp536 was cis-regulated by SenZfp536,which facilitates looping between the promoter of Zfp536 and the genomic region that transcribes SenZfp536.Surprisingly,knocking down or activating the expression of SenZfp536 increased or compromised the proliferation of cortical neural progenitor cells(NPCs),respectively.Finally,overexpressing Zfp536 in cortical NPCs reversed the enhanced proliferation of cortical NPCs caused by SenZfp536 knockdown.The study deepens our understanding of how lncRNAs regulate the propagation of cortical NPCs through cis-regulatory mechanisms.Kuan Tian Andi Wang Junbao Wang Wei Li Wenchen Shen Yamu Li Zhiyuan Luo Ying Liu Yan Zhou 2021Neuroscience Bulletin2021,37,2:0
