Aging-associated lncRNAs carry evolutionary constraints and participate in NFκB signaling [ChIRP]

Project description:Aging changes global transcriptome including protein-coding and noncoding RNAs. Whether aging dependent lncRNAs undergo conserved regulation and function still remain unknown. We report aging dependent lncRNAs carry signature of evolutionary constraint and significantly enriched for targets of transcription factors and RNA binding proteins. Aging dependent lncRNAs is conservatively under NFκB pathway regulation. CRISPR screening for NFκB pathway found that aging dependent lncRNAs also extensively regulate NFκB pathway. The human NFKBMARL-1 is an evolutionary conserved lncRNA that can be traced to 29Mya before human. NFKBMARL-1 is induced during aging, inflammation and senescence through NFκB pathway. Reciprocally, NFKBMARL-1 directly regulates NFKBIZ in cis within same topological associated domain (TAD). NFKBMARL-1 binds to enhancer of NFKBIZ and recruits RELA to the NFKBIZ promoters and participates phase separation. These findings reveal that aging dependent lncRNAs are previously under-appreciated contributors to the evolutionary conservation and regulation of NFκB pathway.

KCNQOT1 ChIRP seq and perturbation epigentic profiles [ChIRP]

Project description:To study the molecular function of lncRNA KCNQOT1, we performed ChIRP-seq HEK293T cells, and we knocked it down in NIH3T3 and HEK293T cells, and created knockout of the repeat-rich and non-repeat regions of KCNQOT1 separately in HEK293T cells, then performed H3K9me3 ChIP-seq, DNA methylation MeDIP-seq and RNA-seq in the perturbed and control wild type cells.
