Upregulation of Kruppel-like Factor 4 Gene expression by Allomyrina dichotoma Hemolymph in the INS-1 Pancreatic β-cells

Abstract

The hemolymph of Korean rhinoceros Allomyrina dichotoma consists of blood and lymph in which various kinds of proteins function physiologically. We have previously demonstrated that A. dichotoma hemolymph has the potential to treatment and prevent diabetes through activating transcription factor 3-gene (ATF3) regulation. In this study, we investigate the expression of Kruppel-like factor 4 (KLF4) in A. dichotoma hemolymph-treated INS-1 pancreatic β-cells. The new findings show that A. dichotoma hemolymph, which upregulates KLF4 gene expression in a dose-dependent and timedependent manner. In addition, hemolymph combine with mild endoplasmic reticulum (ER) stress, which also differentially regulates KLF4 gene expression. These results may provide insights to KLF4 gene-related disease therapies through KLF4 gene regulation.
