GSE108972: PEST-domain-enriched tyrosine phosphatase and glucocorticoids as regulators of mast cell signalling

  • Organsim mouse
  • Type RNASEQ
  • Target gene
  • Project ARCHS4

PEST-domain-enriched tyrosine phosphatase (PEP) is a cytoplasmic protein tyrosine phosphatase that regulates immune cell functions, including mast cell functions. Using bone marrow derived mast cells (BMMCs) from PEP+/+ and PEP-/- mice, RNA-seq data showed that dinitrophenol (DNP) - activated PEP-/- BMMCs have misregulated gene expression, with some cytokine/chemokine genes (eg.TNF, IL13, CSF2) showing reduced gene expression in the dinitrophenol (DNP) - activated PEP-/- BMMCs compared to (DNP)-activated PEP+/+ BMMCs. Also, the ability of the glucocorticoid dexamethasone (Dex) to negatively regulate DNP - induced COX-2 gene expression in PEP-/- BMMCs was inhibited compared to the PEP+/+ BMMCs.
