MTMR6 downregulation contributes to cisplatin resistance in oral squamous cell carcinoma.

ABSTRACT:

Background

The therapeutic effectiveness of cisplatin, a widely used chemotherapy drug for oral squamous cell carcinoma (OSCC), is often compromised by resistance, making it difficult to predict treatment outcomes. The role of myotubularin and myotubularin-related (MTMR) genes in cisplatin resistance remains unclear. We aimed to elucidate the molecular mechanisms underlying MTMR6 with cisplatin resistance in OSCC.

Methods

MTMR6 expression was compared between UMSCC1 and cisplatin-resistant UM-Cis cells. Gain- and loss-of-function experiments involving MTMR6 was performed to evaluate its impact on cisplatin resistance. The regulatory role of hsa-miR-544a on MTMR6 expression was explored via antagomir and miRNA mimic assays. The relationship between MTMR6 protein levels and ci
