Abstract (original English)

Abstract Increased visceral fat correlates with a high risk of morbidity and mortality from diabetes and other metabolic diseases. To cope with changes of nutritional status, the adipose tissue undergoes dynamic remodeling, during which adipose derived stem cells (ADSCs) participate through cell proliferation and adipogenic differentiation into mature adipocytes. Besides, beige adipocytes formation from ADSCs, to dissipate energy as heat in mitochondrial via uncoupling protein1 (UCP1) has been proved to improve energy expenditure. Thus, modifying adipose remodeling and promoting beige adipogenesis of ADSCs in visceral fat bring much metabolic benefits. Newly listed LY3298176, an agonist targeted on glucose-dependent insulinotropic polypeptide (GIP) /glucagon-like peptide-1 (GLP-1) receptor, shows outstanding effect of reducing glucose and weight. Due to superior efficacy in dual-target agonist to GLP-1 monotherapy, and the unknown role of GIP in human visceral adipose, we aimed to clarify GIP’s role in undifferentiated ADSCs in vivo. We selected cell model derived from abdominal omental adipose tissue by obtaining ADSCs via primary culture from patients, because of wide-distributed GIP receptors in fat, and the dominant role of abdominal fat in metabolism. Then the cells were allowed to proliferate, or differentiate into adipocytes in the differentiation medium (DM), with or wi
