Summary: Mitochondrially targeted tamoxifen treatment improves glucose tolerance and reduces body weight in pre-diabetic mice by reducing food intake, suppressing adipogenesis, and eliminating senescent cells. This approach shows potential in the treatment of type 2 diabetes mellitus and its related comorbidities, with a complex impact on senescence-related pathologies.

Summary: A diet rich in saturated fat and carbohydrates can cause chronic inflammation in the liver and other organs, leading to nonalcoholic steatohepatitis. This study found that lipotoxicity and glucotoxicity induced by a high-fat and high-fructose diet can promote abnormal immune reactions to PDIA3 in the liver, resulting in liver damage.

Summary: Obesity is linked to metabolic disorders and increased cardiovascular risk. The presence of type 2 diabetes mellitus (T2DM) affects the protein composition in adipose tissue and serum, leading to changes in systemic markers and dysregulation of metabolic pathways in visceral adipose tissue (VAT).

Summary: The study found that vesicles shed by adipocytes from type 2 diabetes patients or insulin-resistant individuals contain protein TSP5 that promotes EMT in breast cancer cells, potentially worsening the prognosis for breast cancer patients. Additionally, the gene expression in these vesicles can affect the prognosis of breast cancer patients.

Summary: This study found that circulating levels of IL-36 gamma were increased in patients with obesity, and decreased after weight and fat loss. The gene expression levels of IL36G were upregulated in visceral adipose tissue and peripheral blood mononuclear cells from patients with obesity. IL-36 gamma plays a role in regulating chronic inflammation in adipose tissue, and serves as a link between adipose tissue biology and obesity-associated comorbidities.

Summary: The study found that epicardial adipose tissue (EAT) treated with high glucose, high palmitate, and lipopolysaccharide released a large amount of proinflammatory cytokines, which may lead to EAT inflammation in patients with type 2 diabetes, causing coronary artery endothelial cell dysfunction.

Summary: This study found that AIP1 plays a crucial role in the development of type 2 diabetes. It regulates the expression of TNF-alpha through multiple inflammatory pathways. AIP1 deficiency leads to increased inflammatory factors and impairs glucose uptake. The loss of AIP1 in human adipocytes activates the JNK, p38 MAPK, and ERK1/2 signaling pathways, and inhibition of these pathways can alleviate insulin resistance caused by AIP1 deficiency.

Summary: This study found that 3-hydroxydecanoate is enriched in the circulation of obese individuals with type 2 diabetes and is associated with chronic inflammation. Administration of 3-hydroxydecanoate to mice promotes immune cell recruitment to adipose tissue, leading to adipose inflammation and increased insulin levels. Furthermore, 3-hydroxydecanoate stimulates migration of human and mouse neutrophils through GPR84 and Gai signaling.

Summary: Obesity and type 2 diabetes (T2D) lead to increased senescence in adipose cells, resulting in dysfunctional cells and elevated levels of the cell cycle regulator cyclin D1 and senescence markers. These findings suggest a crucial role of senescent adipose cells in the development of obesity and diabetes.

Summary: This study reveals that aging enhances atherosclerosis through the increased inflammation of visceral fat. The transplantation of aged fat onto the carotid artery of mice resulted in larger atherosclerotic plaques with increased macrophage numbers. Inflammatory factors secreted by adipose tissue macrophages, including TNF alpha, CXCL2, and CCL2, were found to contribute to the enhancement of atherosclerosis in aging fat transplants.

Summary: The study synthesized three new series of prenylated benzopyrans containing different numbers of isoprenoid units and explored their hPPAR transactivation activity and structure activity relationships. The results demonstrated that 2-prenylated benzopyrans with seven-carbon and nine-carbon side chains are good lead compounds for preventing cardiovascular diseases.

Summary: In this study, we found that the formation of postprandial methylglyoxal (MGO) in plasma and tissues originates from exogenous glucose and the increase in plasma MGO concentration leads to a fast formation of MGO-derived advanced glycation endproducts (AGEs).

Summary: Diabetes is linked to vascular injury and the development of macrovascular complications. Advanced glycation endproducts (AGEs) and the precursor methylglyoxal (MGO) play important roles in connecting diabetes and vascular injury. While most studies have focused on the relationship between AGEs and vascular injury, the effects of MGO on vasculature are less understood. This review explores the mechanisms linking AGEs and MGO to the progression of atherosclerosis. AGEs and MGO are involved in various stages of atherosclerosis, but further research is needed to understand the exact underlying mechanisms. Nonetheless, targeting AGEs and MGO could provide therapeutic strategies for the macrovascular complications of diabetes.

Summary: This study aimed to evaluate the effects of Fingolimod treatment on PPAR and CD36 gene expression. The results showed that Fingolimod treatment increased HDL-Cholesterol and Apolipoprotein E levels, as well as leukocyte PPAR gamma and CD36 gene expression. Additionally, the variations in PPAR gamma and CD36 were significantly correlated during therapy and in patients with stable disease.

Summary: E2F1 is a crucial factor for maintaining pancreatic β-cell identity and function, and its loss leads to impaired glucose tolerance, defective insulin secretion, downregulation of many β-cell genes, and upregulation of non-β-cell markers. Mechanistically, E2F1 directly regulates several β-cell genes at the chromatin level, and its dysregulation disrupts the transcriptional programs of both β-cells and non-β-cells, resulting in loss of β-cell identity and function.
