Analysis on the transcriptomic changes by LINE-1 overexpression with CRISPRa in NIH3T3 cells

Project description:We report the transcriptomic changes caused by activation of a class of endogenous retroelements long interspersed nuclear elements-1 (LINE-1) by CRISPR activation module. Using lentiviruses, we generated dCas9-CRISPR activator-stably expressing NIH3T3 cells and transfected the sgRNA plasmid targeting the promoter sequence of evolutionally young LINE-1 family (Tf family). RNA was extracted from those cells, sequenced, and analyzed for transcriptome of both cellular genes as well as retroelements expression. The results showed significant upregulation of anti-viral genes and interferon stimulated genes as well as many genes related to cellular homeostasis. This is the first detailed transcriptomic analysis of gene expression perturbation in the cells in which LINE-1 is directly targeted via its promoter and upregulated.

Effects of Nogo-B receptor overexpression on transcriptomic profiling in the NIH3T3 fibroblast cell line

Project description:Unrestrained receptor tyrosine kinase (RTK) signaling and epigenetic dysregulation are responsible in part for tumorigenesis. Aberrant RTK signaling results in the remodeling of histone modification. As a Ras modulator, NgBR promotes Ras-mediated RTK signaling pathways. Meanwhile, we observed that NgBR overexpression in NIH3T3 cells significantly increased the acetylation of histone H3 and histone H4. To further elucidate the underlying mechanism that NgBR upregulates histone acetylation in tumorigenesis, we carried out RNA-seq analysis to examine the transcriptome alternation in NIH3T3 cells and NgBR-overexpressed NIH3T3 cells (3T3NgBR cells) and revealed that overexpression of NgBR up-regulates ACSS2 expression, but not ACSS1 and ACSS3. Moreover. ACSS2 overexpression abrogated NgBR deficiency-caused decrease of histone acetylation in NIH3T3 cells. Taken together, all the data suggested that NgBR regulates tumorigenesis in NIH3T3 cells via ACSS2-mediated histone acetylation.

RNA-seq of human liver cancer cell lines after lncRNA overexpression with CRISPRa

Project description:Biological replicates of Human liver cancer cell line Huh7 (n = 2-4) were treated with CRISPRa to overexpress (OE) LINC00326, LINC01419, LINC02119, novel lncRNAs MSTRG.12891, as well as and non-targeting (NT) control. Cells were harvested 48hrs after transfection. Total RNA was extracted and sequenced with a strand-specific paired end RNA-seq protocol.
