The Role of Semaphorins in Metabolic Disorders.

ABSTRACT: Semaphorins are a family originally identified as axonal guidance molecules. They are also involved in tumor growth, angiogenesis, immune regulation, as well as other biological and pathological processes. Recent studies have shown that semaphorins play a role in metabolic diseases including obesity, adipose inflammation, and diabetic complications, including diabetic retinopathy, diabetic nephropathy, diabetic neuropathy, diabetic wound healing, and diabetic osteoporosis. Evidence provides mechanistic insights regarding the role of semaphorins in metabolic diseases by regulating adipogenesis, hypothalamic melanocortin circuit, immune responses, and angiogenesis. In this review, we summarize recent progress regarding the role of semaphorins in obesity, adipose inflammation, and diabetic complications.

Project description:BACKGROUND: The study was designed to evaluate the association of GATA4 gene polymorphism with coronary artery disease (CAD) and its metabolic risk factors, including dyslipidaemic disorders, obesity, type 2 diabetes and hypertension, following a preliminary study linking early onset of CAD in heterozygous familial hypercholesterolaemia to chromosome 8, which harbours the GATA4 gene. RESULTS: We first sequenced the whole GATA4 gene in 250 individuals to identify variants of interest and then investigated the association of 12 single-nucleotide polymorphisms (SNPs) with the disease traits using Taqman chemistry in 4,278 angiographed Saudi individuals. Of the studied SNPs, rs804280 (1.14 (1.03 to 1.27); p?=?0.009) was associated with CAD (2,274 cases vs 2,004 controls), hypercholesterolaemia (1,590 vs 2,487) (1.61 (1.03-2.52); p?=?0.037) and elevated low-density lipoprotein-cholesterol (hLDLC) (575 vs 3,404) (1.87 (1.10-3.15); p?=?0.020). Additionally, rs3729855_T (1.52 (1.09-2.11; p?=?0.013)) and rs17153743 (AG?+?GG) (2.30 (1.30-4.26); p?=?0.005) were implicated in hypertension (3,312 vs 966), following adjustments for confounders. Furthermore, haplotypes CCCGTGCC (?2?=?4.71; p?=?0.041) and GACCCGTG (?2?=?3.84; p?=?0.050) constructed from the SNPs were associated with CAD and ACCCACGC (?2?=?6.58; p?=?0.010) with myocardial infarction, while hypercholesterolaemia (?2?=?3.86; p?=?0.050) and hLDLC (?2?=?4.94; p?=?0.026) shared the AACCCATGT, and AACCCATGTC was associated with hLDLC (?2?=?4.83; p?=?0.028). A 10-mer GACCCGCGCC (?2?=?7.59; p?=?0.006) was associated with obesity (1,631 vs 2,362), and the GACACACCC (?2?=?4.05; p?=?0.044) was implicated in type 2 diabetes mellitus 2,378 vs 1,900). CONCLUSION: Our study implicates GATA4 in CAD and its metabolic risk traits. The finding also points to the possible involvement of yet undefined entities related to GATA4 transcription activity or gene regulatory pathways in events leading to these cardiovascular disorders.
