Abstract:
:Pancreatic stellate cells (PSCs) secrete various factors, which can influence the β-cell function. The identification of stellate cell infiltration into the islets in pancreatic diseases suggests possible existence of cross-talk between these cells. To elucidate the influence of PSCs on β-cell function, mouse PSCs were cocultured with Min6 cells using the Transwell inserts. Glucose-stimulated insulin secretion from Min6 cells in response to PSCs was quantified by enzyme-linked immunosorbent assay and insulin gene expression was measured by quantitative polymerase chain reaction. Upon cytometric identification of IL6 in PSC culture supernatants, Min6 cells were cultured with IL6 to assess its influence on the insulin secretion and gene expression. PLC-IP3 pathway inhibitors were added in the cocultures, to determine the influence of PSC-secreted IL6 on Glucose-stimulated insulin secretion from Min6 cells. Increased insulin secretion with a concomitant decrease in total insulin content was noticed in PSC-cocultured Min6 cells. Although increased GSIS was noted from IL6-treated Min6 cells, no change in the total insulin content was noted. Coculture of Min6 cells with PSCs or their exposure to IL6 did not alter either the expression of β-cell-specific genes or that of miRNA-375. PSC-cocultured Min6 cells, in the presence of PLC-IP3 pathway inhibitors (U73122, Neomycin, and Xestospongin C), did not revoke the observed increase in GSIS. In conclusion, the obtained results indicate that augmented insulin secretion from Min6 cells in response to PSC secretions is independent of IL6-mediated PLC-IP3 pathway.
