Description
Cancer‐associated fibroblasts (CAF), derived from stroma of cancer tissues, interact with cancer cells and play an important role in cancer initiation, growth, and metastasis. Nab‐paclitaxel (nab‐PTX) is a 130 nm albumin‐binding paclitaxel and recommended for many types of cancer chemotherapy. The nab‐PTX stromal‐disrupting effect during pancreatic cancer treatment has been reported. The aim of the present study was to determine the role of nab‐PTX in cancer cells and CAF interaction. Cancer cells (MIA PaCa‐2 and Panc‐1) were cocultured with CAF or treated with CAF conditioned medium, after which their migration and invasion ability, epithelial‐mesenchymal transition (EMT)‐related marker expression and C‐X‐C motif chemokine 10 (CXCL10) expression and secretion were detected. Nab‐PTX treatment was carried out during the coculture system or during preparation of CAF conditioned medium. Then cancer cell migration and invasion ability, EMT‐related marker expression, CXCL10 expression and secretion, and interleukin‐6 (IL‐6) expression and secretion by CAF were checked After coculture with CAF, migration and invasion ability of cancer cells increased. CAF also downregulated E‐cadherin and upregulated N‐cadherin and vimentin expression in cancer cells. During coculture or stimulation with cancer cell‐cultured medium, CAF significantly increased IL‐6 expression and secretion. However, nab‐PTX in the coculture system canceled CAF‐induced migration and invasion promotion and EMT-related gene changes. Moreover, nab‐PTX increased CXCL10 expression of cancer cells which blocked CAF IL‐6 expression and secretion. Nab‐PTX treatment could increase CXCL10 expression of cancer cells which blocks CAF cancer cell migration and invasion‐promoting effect by inhibiting IL‐6 expression.
