Achieving metabolic homeostasis is necessary for survival, and many genes are required to control organismal metabolism. A genetic screen in larvae identified putative fat storage genes including . has been shown to act in neurons to regulate larval lipid storage; however, whether functions to regulate adult metabolism is unknown. males store more fat than controls while both groups eat similar amounts. flies express more brummer lipase and less of the glycolytic enzyme triose phosphate isomerase, which may contribute to excess fat observed in these mutants. These results suggest that regulates adult lipid homeostasis.

Background: Insulin resistance (IR) is a common pathophysiologic feature in patients with polycystic ovary syndrome (PCOS). However, there have been no studies investigating the association of IR surrogates with pregnancy outcomes in women with PCOS undergoing in vitro fertilization (IVF). Therefore, we explored the association between these factors among PCOS patients.

Amino acid starvation by the chemotherapy agent asparaginase is a potent activator of the integrated stress response (ISR) in liver and can upregulate autophagy in some cell types. We hypothesized that autophagy related 7 (ATG7), a protein that is essential for autophagy and an ISR target gene, was necessary during exposure to asparaginase to maintain liver health. We knocked down Atg7 systemically (Atg7) or in hepatocytes only (ls-Atg7KO) in mice before exposure to pegylated asparaginase for 5 d.

The disorders of glucose and lipid metabolism contribute to severe diseases, including cardiovascular disease, diabetes, and fatty liver. Here, we identified DNA damage-binding protein 2 (DDB2), an E3 ubiquitin ligase, as a pivotal regulator of lipid metabolism disorders in type II diabetes mellitus (T2DM). A mouse model of T2DM and primary mouse hepatocytes with steatosis were induced.

Background: Melittin, a major peptide component of bee venom, has demonstrated promising anti-cancer activity across various preclinical cell models, making it a potential candidate for cancer therapy. However, its molecular mechanisms, particularly in ovarian cancer, remain largely unexplored. Ovarian cancer is a life-threatening gynecological malignancy with poor clinical outcomes and limited treatment options.

: Endothelial peroxisome proliferator-activated receptor gamma (PPARγ) regulates adipose tissue by facilitating lipid uptake into white adipocytes, but the role of endothelial lipid transport in systemic energy balance remains unclear. Ghrelin conveys nutritional information through the central nervous system and increases adiposity, while deficiency in its receptor, growth hormone secretagogue-receptor (GHSR), suppresses adiposity on a high-fat diet. This study aims to examine the effect of ghrelin/GHSR signaling in the endothelium on lipid metabolism.
