Abstract (original English)
Adipocytes are the main stromal cells in the mammary microenvironment, and crosstalk between adipocytes and breast cancer cells may play a critical and important role in cancer maintenance and progression. Tumor‑induced differentiation to beige/brown adipose tissue is an important contribution to the hypermetabolic state of breast cancer. However, the effect of epithelial cell‑beige adipocyte communication on tumor progression remains unclear. To contribute to the understanding of this phenomenon, we characterized components present in conditioned media (CM) from beige adipocytes (BAs) or white adipocytes (WAs), and evaluated the effects of BA‑ and WA‑CM on both adhesion and migration of tumor (LM3, 4T1 and MC4‑L1) and non‑tumor (NMuMG) mouse mammary epithelial cell lines. Additionally, we analyzed the expression of ObR, CD44, vimentin, MMP‑9, MCT1 and LDH in tumor and non‑tumor mouse mammary epithelial cell lines incubated with BA‑CM, WA‑CM or Ctrol‑CM (control conditioned media). 3T3‑L1 preadipocytes differentiated into beige adipocytes upon PPARγ activation (rosiglitazone) displaying characteristics that morphologically resembled brown/beige adipocytes. Levels of UCP1, CIDEA, GLUT4, leptin, MCT4 and FABP4 were increased, while adiponectin, caveolin 1 and perilipin 1 levels were decreased in BAs with respect to WAs. Tumor cell lines revealed lower cell adhesion and increased
