    ..Identification of functional TRPV1, TRPM8, TRPA1 and CB1 expression in these tissues may provide novel drug targets for treatment of this aggressive neoplastic disease. ..

    ..Moreover, there is an inverse association between changes in TRPM8 and TRPV1 activity since these cooling agents blocked both CAP-induced TRPV1 activation and downstream rises in IL-6 release. ..

    ..Taken together, TRPM8 activation by 3T1AM markedly attenuates and even eliminates hyperosmolar and CAP induced TRPV1 activation through crosstalk. ..

    ..Another possible upshot of future studies is that disease process progression can be better evaluated by profiling changes in tissue specific functional TRP subtype activity as well as their gene and protein expression. ..

    ..The regulation of NT secretion in NETs by TRPM8 may have a potential clinical implication in diagnosis or therapy. ..

    ..We conclude that HCEC possess in addition to thermosensitive TRPV3 activity TRPV1, TRPV2, and TRPV4 activity. Their activation confers temperature sensitivity at the ocular surface, which may protect the cornea against such stress. ..

Thermo-sensitive transient receptor potential vanilloid channel-1 regulates intracellular calcium and triggers chromogranin A secretion in pancreatic neuroendocrine BON-1 tumor cells. Cell Signal. 2012;24:233-46 pubmed publisher
    ..Activation of TRPV1 translates into changes of intracellular Ca(2+), a known mechanism triggering the secretion of CgA. The clinical relevance of TRPV1 activation in NETs requires further investigations. ..

    ..There is functional TRPV4 expression in HCEC-12 and in its clonal daughter cell lines based on Ca(2+) transients and underlying currents induced by known activators of this channel. ..

    ..In conclusion, conjunctiva express TRPV1, TRPV2, and TRPV4 channels which may provide novel drug targets for dry eye therapeutics. Their usage may have fewer side effects than those currently encountered with less selective drugs. ..

    ..Taken together, functional TRPM8 expression in HCEC-12 and freshly dissociated HCEC suggests that HCE function can adapt to thermal variations through activation of this channel subtype. ..
