Project description:Cancer cells often rely on aerobic glycolysis for metabolism, and lactylation, a newly discovered post-translational modification, significantly impacts molecular processes. This study comprehensively analyzes lactylation's role in oral squamous cell carcinoma (OSCC), providing initial insights into its impact on progression. Oral squamous cell carcinoma cell lines, before and after lactate treatment, underwent CUT&TAG, ATAC, and transcriptomic sequencing. ChIP-qPCR and RT-qPCR validated results in OSCC tissues. Integrated analysis identified 217 genes with increased expression driven by lactylation in OSCC. Lactylation broadly impacted pathways in cancer, notably regulating PI3K/AKT and MAPK signaling. This pioneering study analyzes lactylation in OSCC, providing a global map of its regulation in oral squamous cell carcinoma from the perspective of chromatin-driven gene expression.

Project description:In an attempt to further elucidate the pathomechanisms in oral squamous cell carcinoma (OSCC), gene expression profiling to a set of 35 primary OSCCs compared to 6 oral mucosa from healthy non-tumor patients was performed. Keywords: expression profiling
Project description:To further development of gene expression approach to squamous carcinoma, we have employed whole genome microarray expression profiling as a discovery platform to identify genes with the potential to reveal the relation between oral squamous carcinoma (OSCC) and human normal oral mucosal epithelial keratinocytes.
Project description:Gene expression profiling of CAF co-cultured with human oral squamous cell carcinoma (OSCC) cells compared with mono-cultured CAF. To identify key molecular regulators expressed by carcinoma-associated fibroblasts (CAF) that promote cancer cell invasion, microarrays were performed by comparing co-cultured OSCC cells and CAF with monoculture controls.
Project description:Gene Expression Profiling of Oral Squamous Cell Carcinoma (OSCC) was performed to delineate candidate genes clusters with potential to distinguish normal and tumor tissue from oral cavity. All tissue samples were collected after obtaining written informed consent.

Project description:The development of oral squamous cell carcinoma (OSCC) is a multistep process requiring the accumulation of genetic alterations. Oral carcinogenesis is a multifactorial process involving numerous genetic changes that affect the activity of oncogenes, tumor suppressor genes and other classes of disease-related genes.Therefore, to identify the responsive genes for progression of oral dysplasia or OSCC, we here performed CGH analysis to DNA from oral dysplasia and OSCC by microdissection Copy number analysis of Affymetrix 250K SNP arrays was performed for 8 oral dysplasia samples, 8 oral squamous cell carcinoma samples, using microdissection
