Abstract
Histone lysine lactylation (Kla) plays a vital role in cancer progression. However, the prognostic value of histone Kla in oral squamous cell carcinoma (OSCC) remains unclear. OSCC RNA expression data were obtained from the TCGA and GEO databases. We explored the prognostic value of histone Kla in OSCC via constructing a Cox model and determined the role of Kla in OSCC drug susceptibility and tumor microenvironment (TME). In addition, the biological roles of candidate biomarkers were identified. A total of 1223 Kla-specific genes were obtained, with 228 DEKlaGs in OSCC. GO and KEGG enrichment analyses suggested that DEKlaGs contributed to inflammatory and cancer progression. A Cox model in accordance with BCAM, CGNL1, DGKG, and OLR1 could predict OSCC patient prognosis accurately. Subsequently, Kla-induced prognostic genes were identified to play a crucial role in OSCC drug therapy and TME. Moreover, BCAM was identified as a biomarker that promoted OSCC invasion, angiogenesis, and chemotherapy resistance. Kla was identified to be associated with OSCC prognosis, drug therapy, and TME. Histone Kla-induced BCAM was identified to play a crucial role during OSCC progression, suggesting that Kla is promising to be a novel therapeutic target for OSCC.
