Identification of biological processes and signaling pathways for the knockout of REV-ERB in mouse brain

Abstract

REV-ERB is an orphan nuclear receptor that is widely expressed in the brain and inhibits transcriptional activities. A variety of genes affect the activity and expression of REV-ERB. In this study, our objective is to identify significant signaling pathways and biological processes in the knockout of the REV-ERB mouse brain. The GSE152919 dataset was originally created by using the Illumina HiSeq 4000 (Mus musculus). The KEGG and GO analyses suggested that biological processes “PPAR signaling”, “Hippo signaling”, and “Hypertrophic cardiomyopathy (HCM)” are mostly affected in the knockout of REV-ERB. Furthermore, we identified a number of genes according to the PPI network including NPAS2, CRY2, BMAL1, and CRY1 which were involved in the lack of REV-ERB in the brain. Therefore, our study provides further insights into the study of circadian clocks.

Genomic analyses identify signaling pathways and biological processes in small and large melanoma

“…The data were organized and conducted by the R package as previously described [10][11][12][13][14][15] . We used a classical t-test to identify DEGs with P < 0.01 and fold change ≥ 1.5 as being statistically signi cant.…”
