Background: Lack of vitamin D (VD) has been associated with colorectal cancer (CRC). VD has anti-inflammatory effects and regulates several cellular pathways by means of its receptor, including epigenetic modifications. Adipose tissue dysfunction has been related to low-grade inflammation, which is related to diseases like cancer. The aim of this study was to explore the relationship between serum 25-hydroxyvitamin D (25(OH)D), adipose tissue gene expression of VD receptor (VDR), pro-inflammatory markers, and the epigenetic factor DNA methyltransferase 3a (DNMT3A) as well as VDR promoter methylation in CRC.
Methods: Blood and visceral adipose tissue from 57 CRC and 50 healthy control subjects were collected. CRC subjects had lower serum 25(OH)D levels and higher VDR gene expression, and these were negatively correlated in the CRC group.
Results: Adipose tissue , , and gene expression were higher in the CRC subjects than in the control subjects. 25(OH)D correlated negatively with and CRP. In turn, CRP correlated positively with , , , and gene expression as well as that correlated positively with and . mRNA was negatively correlated with serum 25(OH)D and positively correlated with DNA methylation. DNA methylation at position 4 had lower levels in the CRC group. Global methylation at dinucleotide 3 was lower in the CRC group.
Conclusion: Our results suggest that adipose tissue may be a key factor in CRC development. The low 25(OH)D levels and high adipose tissue expression in CRC may, at least in part, mediate this relationship by modifying adipose tissue DNA methylation and promoting inflammation.

An insight on the additive impact of type 2 diabetes mellitus and nonalcoholic fatty liver disease on cardiovascular consequences.

Background: Nonalcoholic fatty liver disease (NAFLD) and type 2 diabetes mellitus (T2DM) are associated with a multifactorial complicated aetiology that is often coexisting and has a strong and distinct connection with cardiovascular diseases (CVDs). In order to accomplish effective and appropriate therapeutic strategies, a deeper understanding of the bidirectional interaction between NAFLD patients, NAFLD patients with T2DM, and NAFLD patients with CVDs is required to control the concomitant rise in prevalence of these conditions worldwide. This article also aims to shed light on the epidemiology and mechanisms behind the relationship between T2DM, NAFLD and the related cardiovascular consequences.

Although the role of low-level laser therapy (LLLT) and human adipose-derived stem cells (hADSC) in accelerating diabetic wound healing has been proven, their synergistic effect is still debated. This study aimed to evaluate the individual and combined effects of LLLT and hADSC on wound healing and on biomechanical parameters in type 2 diabetic rabbits. In this experimental study, 40 rabbits with type 2 diabetes (induced by streptozotocin (STZ)) were included.

Studies of the aging transcriptome focus on genes that change with age. But what can we learn from age-invariant genes-those that remain unchanged throughout the aging process? These genes also have a practical application: they can serve as reference genes in expression studies. Reference genes have mostly been identified and validated in young organisms, and no systematic investigation has been done across the lifespan.

Type 2 diabetes mellitus (T2DM) is closely associated with obesity, while interactions between the two diseases remain to be fully elucidated. To this point, we offer this perspective to introduce a set of new insights into the interpretation of T2DM spanning the etiology, pathogenesis, and treatment approaches. These include a definition of T2DM as an energy surplus-induced diabetes characterized by the gradual decline of β cell insulin secretion function, which ultimately aims to prevent the onset of severe obesity through mechanisms of weight loss.

Graphical Abstract Lipoprotein lipase (LPL) mediates peripheral tissue triglyceride (TG) uptake. Hepatic ANGPTL3 (A3) and ANGPTL8 (A8) form a complex and inhibit LPL activity in the white adipose tissue (WAT) via systematic circulation. ANGPTL4 (A4) is expressed in WAT and inhibits LPL activity locally.
