Several “thermoTRP” channels show altered expression in cancers, though it is unclear if this is a cause or consequence of the disease. Regardless of the underlying pathology, this altered expression may potentially be used for cancer diagnosis and prognostication.“ThermoTRP” expression may distinguish between benign and malignant lesions. For example, TRPV1 is expressed in benign gastric mucosa, but is absent in gastric adenocarcinoma. TRPV1 is also expressed both in normal urothelia and non-invasive papillary urothelial carcinoma, but no TRPV1 expression has been seen in invasive urothelial carcinoma.“ThermoTRP” expression can also be used to predict clinical outcomes. For instance, in prostate cancer, TRPM8 expression predicts aggressive behavior with early metastatic disease. Furthermore, TRPV1 expression can dissect a subset of pulmonary adenocarcinoma patients with bad prognosis and resistance to a number of commonly used chemotherapeutic agents. This review will explore the current state of this rapidly evolving field with special emphasis on immunostains that can already be added to the armoire of diagnostic pathologists.  \nKeywords: Transient Receptor Potential (TRP) channel; “thermoTRP”; cancer diagnosis; prognostication  \n1. TRPs and “ThermoTRPs”: A Brief Introduction to Terminology and Biology  \nCapsaicin is best recognized as the active ingredient in hot chili peppers. Chili pepper is indeed “hot”, because capsaicin and noxious heat activate the very same receptor, now known as transient receptor potential, vanilloid-1, or briefly TRPV1 [1] . The molecular cloning of this receptor earned a Nobel Prize (shared with Ardem Patapoutian) for David Julius in 2021 [2] .  \nTRPV1 is an unusual name for a receptor, and needs some explanation. Vanilloid is used because capsaicin and its ultrapotent analog, resiniferatoxin, share a vanillyl group as a motif essential for bioactivity, but differ completely in the rest of the molecule [3] . The specific binding of resiniferatoxin to a site shared by capsaicin provided the first biochemical proof of the existence of a specific “vanilloid”(capsaicin) receptor [3] . The term “transient receptor potential”(or briefly, TRP) is related to mutant fruit flies. The eye of wild-type fruit flies responds to sustained light stimuli with a lasting inward current. These mutants, however, respond to light stimuli with a transient current [4,5] . Thus,“transient receptor potential”(TRP) is really a misnomer, since the wild-type receptor, infact, produces a lasting current.  \nBased on its structural similarity to other TRP channels, the vanilloid receptor was assigned to this receptor superfamily, within which it has its own s","cbCaieBpd4TQAEkH","https://ap.wps.com/l/cbCaieBpd4TQAEkH","pdf",8119797,"English","# ThermoTRPs: A brief introduction to terminology and biology\n## TRPV1 and the thermoTRP concept\n## TRP superfamily structure and subfamilies\n## TRP channel biology, selectivity, and signaling roles","[{\"question\":\"What are thermoTRPs and why are they important in cancers?\",\"answer\":\"ThermoTRPs are temperature-sensitive transient receptor potential (TRP) channels that act as multifunctional signaling molecules involved in cell growth and differentiation.
