RAB25 and ovarian carcinoma: Ras‐associated binding protein 25 (Rab25) is a member of the Rab small GTPase family that regulates intracellular vesicle trafficking.6 Membrane trafficking is involved in many cellular pathways related to carcinogenesis, such as cell proliferation, invasion, metastasis and polarity loss.7 Jeong8 noted that Rab25 upregulates β1 integrin levels and induces snail and fascin expression, leading to epithelial‐mesenchymal transition (EMT) in breast and ovarian cancer cells.
