The transient receptor potential (TRP) channels are non-selective cation channels that consist of seven subgroups displaying different ion selectivity, physiological functions and activation mechanisms. TRP vanilloid 4 (TRPV4) is a member of TRPV family which shows permeability to both Ca2+ and Na+. It is activated by diverse stimuli including both physical and chemical. TRPV4 is found in various types of tissues such as kidneys, airway smooth muscle and lungs, where it participates in many cellular processes including mechanosensation, cell volume regulation and osmoregulation. This study aimed at investigating the potential role of TRPV4 in colorectal cancer cells. Real time RT-PCR was performed to evaluate TRPV4 mRNA levels in HT-29 and HCT-116 human colorectal cancer cells in comparison with the normal colon CCD-18Co cells. The MTT colorimetric assay was done to assess the effect of a TRPV4 activator GSK1016790A and a TRPV4 inhibitor RN 1734 on the proliferation of human colorectal cancer cells.
