Background: Rab11a, Rab11b, and Rab25 are members of the Rab11 subfamily of small Ras-like GTPases. Unlike universally expressed Rab11, typical Rab25 expression appears to be limited to gastrointestinal mucosa, kidney, and lung (1). Rab25 can associate with apical recycling vesicles to help regulate apical vesicle trafficking (2,3). Research studies indicate that atypical Rab25 expression can be associated with various forms of cancer. Increased Rab25 expression is associated with aggressive growth in ovarian and breast cancer, where Rab25 may inhibit apoptosis and promote cancer cell proliferation and invasion through regulation of vesicle transport and cellular motility (4-7). Interaction between Rab25 and β1 integrin promotes vesicle-mediated transport of integrin to pseudopodial tip membranes, fostering the persistent invasion of tumor cells (8). Conversely, the reported loss of Rab25 expression in a number of breast cancer cases has an unclear effect on cancer pathogenesis (9).

Background: Niemann-Pick C1-like 1 (NPC1L1) is a transmembrane protein that plays a critical role in cholesterol absorption (1). It is highly expressed in small intestine and localized along the brush border in both human and mouse epithelial cells (2,3). NPC1L1 mediates cholesterol uptake via vesicular endocytosis (4). Ezetimibe, a potent cholesterol absorption inhibitor used to treat hypercholesterolemia (5), inhibits cholesterol uptake by preventing NPC1L1 from incorporating into clathrin-coated vesicles (4).
