RNA sequencing analysis of IECs from WT and PIM1+/- mice
PIM1 is constitutively active and involved in various cellular processes, including cell survival, proliferation, and differentiation by phosphorylating a wide range of substrates. We investigated whether PIM1 is involved in the pathogenesis of ulcerative colitis (UC).We performed RNA sequencing analysis in intestinal epithelial cells (IECs) from PIM1-deficient mice and WT mice to study the molecular mechanisms through which PIM1 regulates goblet cell numbers. Overall design: Gene expression profiles of IECs from WT and PIM1+/- mice were generated by deep sequencing, using Illumina NovaSeq 6000.To identify DEGs (differential expression genes) between two different samples, the expression level of each transcript was calculated according to the transcripts per million reads (TPM)method. RSEM was used to quantify gene abundances.
