Transient receptor potential vanilloid-6 (TRPV6) is a cation channel belonging to the TRP superfamily, specifically the vanilloid subfamily, and is the sixth member of this subfamily. Its presence in the body is primarily limited to the skin, ovaries, kidney, testes, and digestive tract epithelium. The body maintains calcium homeostasis using the TRPV6 channel, which has a greater calcium selectivity than the other TRP channels. Several pieces of evidence suggest that it is upregulated in the advanced stages of thyroid, ovarian, breast, colon, and prostate cancers. The function of TRPV6 in regulating calcium signaling in cancer will be covered in this review, along with its potential applications as a cancer treatment target.

Bone metastasis most commonly occurs in castration-resistant prostate cancer (CRPC). The TRPV6 calcium channel is absent in healthy prostate tissue, but its expression increases considerably during cancer progression. We hypothesized that cancer cells induce TRPV6 expression de novo to directly benefit from tightly regulated calcium intake via TRPV6 while providing cancer cells with a selective advantage for metastasis in the calcium-abundant niche, such as bone.

Background & Aims: Suppressing toxic Ca accumulation in pancreatic acinar cells (PACs) is the central therapeutic strategy of acute pancreatitis (AP). Store-operated Ca entry (SOCE) represents an important mechanism promoting Ca overload, which remains incompletely understood in AP. Transient receptor potential vanilloid 6 (TRPV6) is an ion channel highly selective to Ca, and its role in PACs or AP onset remains largely unknown.

Deoxynivalenol (DON), a prevalent mycotoxin contaminant in cereals, compromises intestinal homeostasis by inducing organelle dysfunction, particularly in the endoplasmic reticulum (ER). Despite the critical role of ER stress in intestinal pathology, the precise mechanisms by which DON-induced ER dysfunction affects intestinal stem cell (ISC) fate commitment remain unclear. Here, we demonstrate that acute exposure to DON disrupts jejunal epithelial architecture and impairs barrier integrity in piglets by suppressing ISC proliferation and inhibiting differentiation of epithelial lineages along the crypt-villus axis.

This commentary proposes enhancements to improve a study on cadmium-induced EMT in renal cancer cells. Key recommendations encompass the following aspects: Supplementing statistical power justification through explicit definition of parameters including ≥80% desired power, minimal effect size, and intra-group variability; Report exact P values with confidence intervals to improve statistical transparency; Clarification of p38 MAPK versus cPLA2 pathway contributions via co-inhibition experiments; Exclusion of TRP channel confounding effects when using 2-APB through targeted TRPV6 inhibition; Distinction between direct Cd²⁺ effects and toxicity-induced compensatory responses; Provision of explicit rationale for selecting Mag-Fluo-4/AM and Rhod-2/AM fluorescent probes; Experimental verification of PMCA inhibition synergism with cadmium-induced cytosolic Ca²⁺ overload. These recommendations would enhance the robustness of the original study's conclusions.

Calcium bioavailability and bone mineralization are critical for skeletal health; however, conventional calcium supplements often face limitations in absorption efficiency. This study investigates how enzyme-specific hydrolysis of CN generates bioactive peptides with distinct capacities to promote calcium absorption and bone formation. Papain-derived CN hydrolysate significantly outperformed calcium chloride in restoring bone health in osteoporotic mice, elevating serum osteocalcin levels by 1.
