This study attempted to characterize the functional mechanisms of breast cancer (BC) cell-derived exosome-loaded microRNA (miR)-155 in cancer cachexia-related fat loss. Exosomes were incubated with preadipocytes and cellular lipid droplet accumulation was observed using Oil Red O staining. Western blotting evaluated the cellular levels of lipogenesis marker peroxisome proliferator activated receptor gamma (PPAR\u03b3) and adiponectin, C1Q and collagen domain containing (AdipoQ). Differentiated adipocytes were incubated with exosomes, and phosphate hormone sensitive lipase (P-HSL), adipose triglyceride lipase (ATGL) and glycerol were detected in adipocytes, in addition to uncoupling protein 1 (UCP1) and leptin levels. A mouse model of cancer cachexia was established where cancer exosomes were injected intravenously. The changes in body weight and tumor-free body weights were recorded and serum glycerol levels and lipid accumulation in adipose tissues were determined. Also, the relationship between miR-155 and UBQLN1 was predicted and verified. BC exosome treatment reduced PPAR\u03b3 and AdipoQ protein levels, promoted the levels of P-HSL and ATGL proteins, facilitated glycerol release, increased UCP1 expression and lowered leptin expression in adipocytes. Exosomal miR-155 inhibited lipogenesis in preadipocytes and boosted the browning of white adipose tissues. miR-155 downregulation alleviated cancer exosome-induced browning of white adipose tissues and fat loss. Mechanistically, miR-155 targeted UBQLN1, and UBQLN1 upregulation reversed the impacts of cancer exosomes. miR-155 loaded by BC cell-derived exosomes significantly affects white adipose browning and inhibition of cancer-derived exosomes.<\/jats:p>","DOI":"10.1093\/hmg\/ddad055","type":"journal-article","created":{"date-parts":[[2023,4,5]],"date-time":"2023-04-05T08:02:27Z","timestamp":1680681747000},"page":"2219-2228","source":"Crossref","is-referenced-by-count":25,"title":["RETRACTED: Breast cancer cell-derived exosome-delivered microRNA-155 targets UBQLN1 in adipocytes and facilitates cancer cachexia-related fat loss"],"prefix":"10.1093","volume":"32","author":[{"given":"S","family":"Sun","sequence":"first","affiliation":[{"name":"Department of Clinical Laboratory, Renmin Hospital of Wuhan University , Wuhan, Hubei 430060 ,","place":["P.R.
