Mung bean peptides promote glucose uptake via Jak2 activation in L6 myotubes

Abstract

Mung beans are among the important edible legumes cultivated in Asia, Southern Europe, and Northern America. Mung beans contain 20–30% proteins with high digestibility and possess biological activities, but detailed health beneficial functions are not fully understood yet. In this study, we report the isolation and identification of active peptides from mung beans which promote glucose uptake and elucidate their mechanism in L6 myotubes. HTL, FLSSTEAQQSY, and TLVNPDGRDSY were isolated and identified as active peptides. These peptides promoted the translocation of glucose transporter 4 (GLUT4) to the plasma membrane. The tripeptide HTL promoted glucose uptake through the activation of adenosine monophosphate-activated protein kinase, while the oligopeptides FLSSTEAQQSY and TLVNPDGRDSY through the activation of the PI3K/Akt pathway. Furthermore, these peptides promoted the phosphorylation of Jak2 via interaction with the leptin receptor. Thus, mung bean is a promising functional food for the prevention of hyperglycemia and type 2 diabetes through promoting glucose uptake accompanied by JAK2 activation in the muscle cells.
