However, cell ageing caused by long-term in vitro expansion and poor survival after in vivo delivery greatly limits their success in preclinical and clinical applications. Dedifferentiation represents a potential strategy for enhancing the retention and function of MSCs in hostile environments. In this study, we evaluated the cell phenotype, proliferation, and differentiation potential, as well as the anti-oxidative stress ability of human umbilical cord-derived MSCs (hMSCs) manipulated with adipogenic priming and subsequent dedifferentiation. After an in vitro differentiation and dedifferentiation procedure, the resultant dedifferentiated hMSCs (De-hMSCs) displayed properties similar to their original counterparts, including immunophenotype and mesodermal potential. Upon re-induction, De-hMSCs exhibited a significantly higher adipogenic differentiation capability than unmanipulated hMSCs. Importantly, De-hMSCs showed a significantly enhanced ability to resist tert-butyl hydroperoxide (t-BHP) induced apoptosis compared to undifferentiated hMSCs. Mechanisms involving bcl-2 family proteins and autophagy may contribute to the demonstrated advantages of dedifferentiation-reprogrammed hMSCs. These results indicate that adipogenic dedifferentiation promotes adipogenesis and cell persistence, as well as preserves the stemness of human umbilical cord-derived MSCs that have been committed to the adipocytic lineage. As a unique stem cell population, dedifferentiated MSCs may represent an attractive and promising candidate for MSC-based therapy.","PeriodicalId":7226,"journal":{"name":"Adipocyte","volume":"14 1","pages":"2467150"},"PeriodicalIF":3.5,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11845070/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143456410","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Their clinical profile included childhood-onset extreme weight gain, intense hunger, hyperphagia, hypogonadotropic hypogonadism, and family history of obesity. Direct sequencing of the LEP gene revealed a novel homozygous missense mutation in exon 3 (c.350G>T [p.C117F]). The presence of this mutation, undetectable leptin, and severe obesity confirmed a diagnosis of monogenic leptin deficiency. Here we describe the clinical outcomes of a 12-month treatment with recombinant human leptin (metreleptin). Metabolic and endocrine assessments were conducted before and after therapy. Metreleptin therapy significantly reduced BMI: from 59 to 38 kg/m2 (OBX1, age 27) and 60 to 48 kg/m2 (OBX2, age 24). Total body fat mass decreased, serum lipids normalized, and insulin sensitivity improved. Hypogonadotropic hypogonadism reversed, and menstruation resumed. Thus, metreleptin reversed the major metabolic and endocrine abnormalities associated with leptin deficiency in these sisters. Limitations include the small sample size, absence of a control group, and lack of anti-metreleptin antibody measurements. Nevertheless, our findings support that leptin replacement with metreleptin is currently the only effective hormonal treatment for this monogenic form of human obesity.","PeriodicalId":7226,"journal":{"name":"Adipocyte","volume":"14 1","pages":"2508188"},"PeriodicalIF":3.5,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12118419/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144141245","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Angiotensin 1-7 (Ang 1-7), a component of the renin-angiotensin system (RAS), exhibits anti-inflammatory effects in obesity and related disorders, though its mechanisms remain unclear. In this study, we examined the effect of Ang 1-7 on inflammation of white adipose tissue (WAT) in dietary-induced obese mice. Monocyte chemoattractant protein-1 (MCP-1) produced by white adipocytes and tumour necrosis factor-α (TNF-α) produced by macrophages are pro-inflammatory cytokines and interact to form a pathogenic loop to exacerbate obesity-induced inflammation. We found that Ang 1-7 reduced MCP-1 and TNF-α gene expressions and the number of crown-like structures, which are histological hallmarks of the pro-inflammatory process, in visceral epididymal WAT (eWAT) and reduced circulating MCP-1 and TNF-α levels, accompanied by improvement in insulin resistance, in dietary-induced obese mice. Furthermore, Ang 1-7 reduced MCP-1 and TNF-α secretions in 3T3-L1 white adipocytes and RAW 264.7 macrophages, respectively, which are in vitro experimental models mimicking obesity condition. Our results suggest that Ang 1-7 directly acts on WAT to mitigate obesity-induced inflammation.

The results indicated that the levels of SDF-1 and its receptors, CXCR7 and CXCR4, decreased during the early stages of adipogenesis. Treatment with recombinant SDF-1 and CCX771 inhibited adipogenesis and lipid accumulation by inducing β-arrestin2, Wnt expression, and AKT phosphorylation and downregulating C/EBPα, PPARγ, and FABP4 expression. In contrast, knockdown of SDF-1 and CXCR7 in preadipocytes downregulated the β-arrestin2/Wnt and AKT pathway, leading to the induction of adipogenesis. Meanwhile, knockdown of CXCR4 had no significant effect. In mice, basal gene expression levels of SDF-1 and CXCR7 were higher in the stromal vascular fraction compared to mature adipocytes and were significantly upregulated by a high-fat diet.

Chemotherapy, one of the main cancer treatments, worsens weight loss in cancer-induced cachexia. In this context, it is thought that fat loss precedes muscle loss, and that alterations in adipose tissue are associated with tumours. However, the effect of cancer treatment on adipose tissue is not well understood. This study aimed to evaluate the impact of chemotherapy alone on mature 3T3-L1 adipocytes to identify the mechanisms contributing to adipose tissue alteration. The murine cell line 3T3-L1, a model of mature adipocytes, was used in this study. After differentiation, cells were treated for 48 h with a chemotherapy cocktail called FLOT composed of 5-fluorouracil, leucovorin, oxaliplatin and docetaxel at two concentrations (FLOT 1X and 0.1X). The control group was treated with the vehicle of the chemotherapy cocktail. Viability, mitochondrial function and dynamics, lipid metabolism, and cellular stress were also evaluated. FLOT 1X chemotherapy significantly reduced viability of mature 3T3-L1 cells and inhibited lipid accumulation. Interestingly, while FLOT 1X treatment downregulated lipogenesis markers, FLOT 0.1X treatment upregulated some of them. Although, the treatment showed no effect on mitochondrial respiration or density, it significantly increased expression of oxidative stress and inflammation markers in adipocytes.This in vitro study provides the first evidence of FLOT chemotherapy's direct effects on healthy mature adipocytes. The results demonstrate significant treatment-induced reductions in cell viability along with dysregulation of both lipogenic and lipolytic pathways. These findings elucidate previously unrecognized mechanisms underlying adipose tissue dysfunction in cancer cachexia.","PeriodicalId":7226,"journal":{"name":"Adipocyte","volume":"14 1","pages":"2518285"},"PeriodicalIF":3.5,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144339800","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
