Summary: Microarray analysis identified a total of 63 annotated genes differentially expressed between stable CTSH-overexpressing insulin-secreting INS-1 cells and control cells transfected with an empty vector after treatment with IL-1β and IFNγ for 0, 6 and 16 hours. Permutation test taking all time-points into consideration identified 10 genes differentially expressed between the CTSH-overexpressing cells and the control cells: Elmod1, Fam49a, Gas7, Gna15, Msrb3, Nox1, Ptgs1, Rac2, Scn7a and Ttn. Pathway analysis identified one significant pathway “Inflammation mediated by chemokine and cytokine signaling pathway” with the genes Gna15, Ptgs1 and Rac2. Since Gna15 and Rac2 were upregulated by CTSH overexpression, their expression was knocked down using small interfering RNAs (siRNAs) to evaluate their potential as mediators of the protective effect of CTSH. Knockdown of Rac2 abolished the protective effect of CTSH overexpression on cytokine-induced apoptosis.
