Research Article: Syndecan-4 as a genetic determinant of the metabolic syndrome

Date Published: 2023-08-03

Abstract:
Syndecan-4 (SDC4) is a member of the heparan sulfate proteoglycan family of cell-surface receptors. We and others previously reported that variation in the SDC4 gene was associated with several components of the metabolic syndrome, including intra-abdominal fat, fasting glucose and triglyceride levels, and hypertension, in human cohorts. Additionally, we demonstrated that high fat diet (HFD)-induced obese female mice with a Sdc4 genetic deletion had higher visceral adiposity and a worse metabolic profile than control mice. Here, we aimed to first investigate whether the mouse Sdc4 null mutation impacts metabolic phenotypes in a sex- and diet-dependent manner. We then tested whether SDC4 polymorphisms are related to the metabolic syndrome (MetS) in humans.

Introduction:
Metabolic syndrome (MetS) is a cluster of inter-related and partly heritable metabolic disorders that include abdominal obesity, hyperglycemia, dyslipidemia, and hypertension [1, 2]. Together these factors dramatically increase the risk of developing atherosclerotic cardiovascular disease, insulin resistance, and diabetes mellitus [3, 4], as well as premature death [5, 6]. Given its adverse outcomes and high prevalence worldwide, ranging from 12.5 to 31.4% [7], MetS has become a serious global health issue that is…
