Article Abstract
The family with sequence similarity 13 member A (FAM13A) gene has been discovered in recent years and is related to metabolism. In this study, the function of FAM13A in precursor adipocyte proliferation in Qinchuan cattle was investigated using fluorescence quantitative polymerase chain reaction (PCR), western blotting, 5-ethynyl-2'-deoxyuridine staining, and other tests. FAM13A promoted precursor adipocyte proliferation. To determine the pathway FAM13A was involved in, transcriptome sequencing, fluorescence quantitative PCR, western blotting, and other tests were used, which identified the hypoxia inducible factor-1 (HIF-1) signalling pathway. Finally, cobalt chloride, a chemical mimic of hypoxia, was used to treat precursor adipocytes. mRNA and protein levels of FAM13A were significantly increased after hypoxia. Thus, FAM13A promoted bovine precursor adipocyte proliferation by inhibiting the HIF-1 signalling pathway, whereas chemically induced hypoxia negatively regulated FAM13A expression, regulating cell proliferation.

Obesity is intricately linked to various metabolic diseases; however, some individuals maintain metabolic health despite being classified as obese. A critical factor underlying this paradox is the expansion of white adipose tissue (WAT), which can occur through two mechanisms: hypertrophy (the enlargement of existing fat cells) and hyperplasia (the formation of new fat cells from adipocyte precursor cells, or APCs). Hyperplasia is regarded as a healthier mode of WAT expansion, as it tends to reduce inflammation and protect against insulin resistance.

Fat depots across the body dynamically tune their sizes in response to nutrient demands and nonmetabolic cues. Writing in Cell Stem Cell, Rivera-Gonzalez et al. report that skin fat, notable for its ability to rapidly expand, harbors molecularly distinct precursors, primed for proliferation and differentiation into mature adipocytes.

Aims: Obesity, driven by complex genetic and environmental interactions, remains a global health crisis with limited therapeutic options. The insulin-like growth factor 1 receptor (IGF1R) plays dual roles in metabolism and growth, but its tissue-specific functions in adipose biology are controversial. This study investigates how adipose-specific IGF1R knockout impacts systemic metabolism under high-fat diet (HFD) stress and explores the underlying mechanisms.

Perfluorooctane sulfonamide (PFOSA) is an indirect source of perfluorooctane sulfonic acid (PFOS) in the environment as a precursor; however, toxicological study of PFOSA is limited. This study aimed to investigate the effects of PFOSA on glucose and lipid metabolism in 3T3-L1 adipocytes and in zebrafish larvae. 3T3-L1 adipocytes were treated with PFOSA, PFOS, and rosiglitazone (RSG) for 48 h, and assessed for cell viability, adipogenesis, glucose uptake, and regarding molecular mechanisms.

Intramuscular fat (IMF) content determines the quality of goat meat and is regulated by the comprehensive effect of the proliferation and adipogenesis of intramuscular preadipocytes. Our previous RNA-seq data revealed that cell death-inducing DNA fragmentation factor alpha (DFFA)-like effector (CIDE) A was upregulated during the development of intramuscular fat in the longissimus dorsi muscle tissue, implying an important role in lipid homeostasis. However, the mechanism by which , a member of the CIDE family, regulates intramuscular fat deposition in goat muscle is unknown, so we explored the function and underlying mechanism of in goat intramuscular preadipocytes.
