Mitogen-activated protein kinase phosphatase-1 prevents lipopolysaccharide-induced apoptosis in immature rat intestinal epithelial cells.

Abstract:

BACKGROUND:Necrotizing enterocolitis is characterized by intestinal inflammation and epithelial barrier dysfunction. Mitogen-activated protein kinase (MAPK) phosphatase (MKP)-1 plays a pivotal role in the feedback control of MAPK signaling, which regulates inflammation and apoptosis. We hypothesized that MKP-1 prevents lipopolysaccharide (LPS)-induced apoptosis in intestinal epithelial cells. METHODS:Western blot analysis and qPCR were used to assess MKP-1, MAPK (p38, extracellular signal-regulated kinase (ERK), and c-Jun N terminal kinases (JNK)), caspase 3, caspase 9, tumor necrosis factor (TNF)-α, and cyclooxygenase (COX)-2 expression levels in rIEC-6 enterocytes. MKP-1 expression was inhibited using small interfering RNA (siRNA) methodology. Viable cell number was determined using trypan blue exclusion. RESULTS:LPS stimulation led to activation of p38, JNK, and ERK, and induction of MKP-1 mRNA and protein expression. The induction of MKP-1 was associated with a decrease in p38 phosphorylation, and knockdown of MKP-1 prolonged p38 phosphorylation. While LPS stimulation significantly attenuated proliferation of rIEC-6 cells transfected with scramble siRNA, LPS stimulation resulted in a net decrease in viable cell number in cells transfected with MKP-1 siRNA. Following LPS stimulation, MKP-1 knockdown resulted in greater caspase 3 and 9 activities and greater proinflammatory cytokine (TNF-α, COX-2) expression than in cells transfected with scramble siRNA. CONCLUSION:Our results demonstrate that MKP-1 has a central role in preventing inflammation-induced apoptosis in rIEC-6 enterocytes.
