1Evolutionary annotation of conserved long non-coding RNAs in major mammalian species显示文摘Mammalian genomes contain tens of thousands of long non-coding RNAs(lnc RNAs) that have been implicated in diverse biological processes. However, the lnc RNA transcriptomes of most mammalian species have not been established, limiting the evolutionary annotation of these novel transcripts. Based on RNA sequencing data from six tissues of nine species, we built comprehensive lnc RNA catalogs(4,142–42,558 lnc RNAs) covering the major mammalian species. Compared to protein-coding RNAs, expression of lnc RNAs exhibits striking lineage specificity. Notably, although 30%–99% human lnc RNAs are conserved across different species on DNA locus level, only 20%–27% of these conserved lnc RNA loci are detected to transcription, which represents a stark contrast to the proportion of conserved protein-coding genes(48%–80%). This finding provides a valuable resource for experimental scientists to study the mechanisms of lnc RNAs. Moreover, we constructed lnc RNA expression phylogenetic trees across nine mammals and demonstrated that lnc RNA expression profiles can reliably determine phylogenic placement in a manner similar to their coding counterparts. Our data also reveal that the evolutionary rate of lnc RNA expression varies among tissues and is significantly higher than those for protein-coding genes. To streamline the processes of browsing lnc RNAs and detecting their evolutionary statuses, we integrate all the data produced in this study into a database named Phylo NONCODE(http://gffzz4d3d7636fb124c4fh0nffwx6u9ufc66p5.ffgz.tsg.suse.edu.cn/phylo Noncode). Our work starts to place mammalian lnc RNAs in an evolutionary context and represent a rich resource for comparative and functional analyses of this critical layer of genome.BU DeChao LUO HaiTao JIAO Fei FANG ShuangSang TAN ChengFu LIU ZhiYong ZHAO Yi 2015Science China(Life Sciences)2015,58,8:3
2Celastrol enhances transcription factor EB (TFEB)-mediated autophagy and mitigates Tau pathology:Implications for Alzheimer's disease therapy显示文摘Alzheimer's disease(AD),characterized by the accumulation of protein aggregates including phosphorylated Tau aggregates,is the most common neurodegenerative disorder with limited therapeutic agents.Autophagy plays a critical role in the degradation of phosphorylated Tau aggregates,and transcription factor EB(TFEB)is a master regulator of autophagy and lysosomal biogenesis.Thus,small-molecule autophagy enhancers targeting TFEB hold promise for AD therapy.Here,we found that celastrol,an active ingredient isolated from the root extracts of Tripterygium wilfordii(Lei Gong Teng in Chinese)enhanced TFEB-mediated autophagy and lysosomal biogenesis in vitro and in mouse brains.Importantly,celastrol reduced phosphorylated Tau aggregates and attenuated memory dysfunction and cognitive deficits in P301S Tau and 3xTg mice,two commonly used AD animal models.Mechanistical studies suggest that TFEB-mediated autophagy-lysosomal pathway is responsible for phosphorylated Tau degradation in response to celastrol.Overall,our findings indicate that Celastrol is a novel TFEB activator that promotes the degradation of phosphorylated Tau aggregates and improves memory in AD animal models.Therefore,Celastrol shows potential as a novel agent for the treatment and/or prevention of AD and other tauopathies.Chuanbin Yang Chengfu Su Ashok Iyaswamy Senthil Kumar Krishnamoorthi Zhou Zhu Sichang Yang Benjamin Chunkit Tong Jia Liu Sravan G.Sreenivasmurthy Xinjie Guan Yuxuan Kan Aston Jiaxi Wu Alexis Shiying Huang Jieqiong Tan Kingho Cheung Juxian Song Min Li 2022Acta Pharmaceutica Sinica B2022,12,4:2
