ABSTRACT
Breast cancer is the most frequently diagnosed cancer in women worldwide. Although dramatically increased survival rates of early diagnosed cases have been observed, late diagnosed patients and metastatic cancer may still be considered fatal. The present study's main focus was on cancerassociated fibroblasts (CAFs) which is an active component of the tumor microenvironment (TME) regulating the breast cancer ecosystem. Transcriptomic profiling and analysis of CAFs isolated from breast cancer skin metastasis, cutaneous basal cell carcinoma, and squamous cell carcinoma unravelled major gene candidates such as IL6, VEGFA and MFGE8 that induced coexpression of keratins8/14 in the EMG3 cell line derived from infiltrating ductal breast carcinoma. Western blot analysis of selected keratins (keratin8, 14, 18, 19) and epithelialmesenchymal transitionassociated markers (SLUG, SNAIL, ZEB1, E/Ncadherin, vimentin) revealed specific responses pointing to certain heterogeneity of the studied CAF populations. Experimental in vitro treatment using neutralizing antibodies against IL-6, VEGFA and MFGE8 attenuated the modulatory effect of CAFs on EMG3 cells. The present study provided novel data in characterizing and understanding the interactions between CAFs and EMG3 cells in vitro. CAFs of different origins support the proinflammatory microenvironment and influence the biology of breast cancer cells. This observation potentially holds significant interest for the development of novel, clinically relevant approaches targeting the TME in breast cancer. Furthermore, its implications extend beyond breast cancer and have the potential to impact a wide range of other cancer types.
