Objective: This paper aims to reveal the impact of HOXC6 on oral cancer development through the regulation of BCAT1 and the molecular mechanism.
Methods: BCAT1 expression in oral cancer tissues and adjacent tissues was verified by western blot analysis and RT-qPCR. After knocking down BCAT1, the HN6 and HN30 cell proliferation, migration, invasion, and apoptosis were detected. The upstream mechanism of BCAT1 elevation was investigated by bioinformatics analysis. HOXC6 expression was detected by immunohistochemistry in oral cancer and adjacent tissues. ChIP and dual-luciferase assay were used to detect the interaction between HOXC6 and the BCAT1 promoter. Rescue experiments were carried out to substantiate the malignant phenotype and epithelial-to-mesenchymal transition (EMT) of oral cancer cells. An in vivo xenograft tumor model was constructed.
Results: BCAT1 and HOXC6 were abnormally high in oral cancer tissues. Inhibition of BCAT1 suppressed the proliferation, migration, invasion, and EMT, and promoted apoptosis of oral cancer cells. HOXC6 downregulation curbed the malignant behavior and EMT program of oral cancer cells. HOXC6 was enriched in the BCAT1 promoter in oral cancer cells. HOXC6 silencing downregulated BCAT1 expression. Transcriptional activation of BCAT1 by HOXC6 promoted oral cancer progression.
Conclusion: HOXC6 knockdown inhibits BCAT1 expression to suppress oral cancer development.

Background: A modified pull-through approach represents a promising treatment strategy to access tumors in the posterior oral cavity. The design of the wedge osteotomy plays a key role in preserving postoperative mechanical stability while enabling surgical access. However, the optimal osteotomy design to reduce fracture risk remains unclear.

Purpose: For submandibular gland resection, conventional surgery with the naked eye remains the standard. With its excellent automatic focus and high magnification, the ORBEYE 3D exoscope enables precise submandibular gland resection with less stress. Therefore, we aimed to examine the usefulness of the exoscope in submandibular gland resection.

The global surge in the population of people 60 years and older, including that in China, challenges healthcare systems with rising age-related diseases. To address this demographic change, the Aging Biomarker Consortium (ABC) has launched the X-Age Project to develop a comprehensive aging evaluation system tailored to the Chinese population. Our goal is to identify robust biomarkers and construct composite aging clocks that capture biological age, defined as an individual's physiological and molecular state, across diverse Chinese cohorts.

Background: Docetaxel is the most common chemotherapy regimen for several neoplasms, including advanced OSCC (Oral Squamous Cell Carcinoma). Unfortunately, chemoresistance leads to relapse and adverse disease outcomes.
Methods: We performed CRISPR-based kinome screening to identify potential players of Docetaxel resistance.
