TRPV1 is a ligand-gated ion channel classically associated with nociception and heat sensation.
- TRPV1 is a nonselective cation channel that allows the influx of calcium (and other cations) when activated by various stimuli such as capsaicin, heat, or low pH.
- TRPV1 can influence key cellular processes including proliferation, apoptosis, and migration by modulating intracellular calcium levels and downstream signaling cascades.
- In some cases, TRPV1 activation can induce cell death, which might translate into less aggressive tumor behavior; however, this is not a universal finding.
- TRPV1 is a non-selective cation channel, which is frequently overexpressed in highly malignant cancers.
- Capsaicin may be able to induce cell death in urothelial cancer and glioma cells via TRPV1-dependent stimulation of excessive calcium (Ca2+) influx
- Activation of TRPV1 promotsd the generation of ROS.
- Variability in TRPV1 expression and function suggests that it might serve as one component of a broader prognostic panel rather than a standalone marker.
