P. micra surface protein TmpC interacts directly with OSCC cell lines via CKAP4


ABSTRACT: P. micra surface protein TmpC interacts directly with OSCC cell lines via CKAP4, a receptor frequently overexpressed in human OSCC tumors. The interaction of TmpC and CKAP4 mediates bacterial attachment, invasion, and metastasis-promoting effects of P. micra on OSCC and subsequently activates HIF-1α and autophagy signaling, via CKAP4-RanBP2 and CKAP4-NBR1 interaction, respectively.

Parvimonas micra (P. micra), an opportunistic oral pathogen associated with multiple cancers, has limited research on its role in oral squamous cell carcinoma (OSCC). This study shows that P. micra is enriched in OSCC tissues and positively correlated with tumor metastasis and stages. P. micra infection promotes OSCC metastasis by inducing hypoxia/HIF-1α, glycolysis, and autophagy. Mechanistically, P. micra surface protein TmpC binds to CKAP4, a receptor overexpressed in OSCC, facilitating bacte  ...[more]
