Objective To explore the expression of TRPV2 and its clinicopathological significance in oral
squamous cell carcinoma (OSCC). Methods Immunohistochemistry and western blot were used to detect TRPV2
expression level in OSCC; Pearson χ2
test to analyze the association between TRPV2 expression level and clinicopathological features of OSCC patients; log-rank test to analyze the effect of TRPV2 on survival. Bioinformatics
method was used to explore the potential biological function of TRPV2, and immunohistochemistry to verify the
relationship between TRPV2 and macrophage infiltration level. Results Immunohistochemistry and western blot
confirmed that TRPV2 was highly expressed in OSCC (P < 0.05). TRPV2 expression was significantly correlated
with T stage, tumor histological grade and poor prognosis (P < 0.05). Bioinformatics method found that TRPV2
participated in PI3K/AKT pathway and regulated the level of immune cell infiltration; TRPV2 expression had
strong positive correlation with the macrophage infiltration level (R = 0.562,P < 0.001). Conclusion The
expression of TRPV2 is highly expressed in OSCC and associated with poor prognosis,and may take part in the
occurrence and development of OSCC by regulating immune response and PI3K/AKT pathway.
