Kinase Signaling in Apoptosis Induced by Saturated Fatty Acids in Pancreatic β-Cells

Publication at Third Faculty of Medicine |

Abstract

Pancreatic -cell failure and death is considered to be one of the main factors responsible for type 2 diabetes. It is caused by, in addition to hyperglycemia, chronic exposure to increased concentrations of fatty acids, mainly saturated fatty acids.

Molecular mechanisms of apoptosis induction by saturated fatty acids in -cells are not completely clear. It has been proposed that kinase signaling could be involved, particularly, c-Jun N-terminal kinase (JNK), protein kinase C (PKC), p38 mitogen-activated protein kinase (p38 MAPK), extracellular signal-regulated kinase (ERK), and Akt kinases and their pathways.

In this review, we discuss these kinases and their signaling pathways with respect to their possible role in apoptosis induction by saturated fatty acids in pancreatic beta-cells.
