Project description:Esophageal cancer comprises two main subtypes: esophageal squamous cell carcinoma (ESCC) and esophageal adenocarcinoma (EAC). Previous studies revealed their distinct genomic characteristics, sharing similarities with head and neck squamous cell carcinoma (HNSCC) and gastric adenocarcinoma (GAC) for ESCC and EAC, respectively. This study compares ESCC and EAC at single-cell resolution to identify factors explaining differences in immunotherapy response rates. We performed comparative single-cell transcriptome analysis for four cancer types near the esophagus using data from 35 patients with ESCC, EAC, HNSCC, or GAC. Malignant epithelial cells showed distinct separations between subtypes based on histological origins. We identified enrichment of CXCL13+ CD8+ T cells and CXCL9+CXCL10+ TAMs in ESCC and HNSCC, promoting a hot-tumor environment through interferon-γ pathways. Conversely, hypoxia and cold-tumor related populations, such as heat-shock protein high CD8+ T cells and MARCO+ TAMs, were enriched in EAC and GAC. These immune subsets' expression signatures predicted immunotherapy responses across diverse cancer types.
Project description:Protein identification in esophageal squamous cell carcinoma(ESCC) was performed,we explored the proteomic landscape in ESCC and attempted to perform clinical-related patient classification based on ESCC proteome.
Project description:HOXC6 is a member of the HOX family, and its aberrant expression has been verified in a variety of cancers, such as prostate, breast,nasopharyngeal carcinoma,gastric, and ovarian cancers.Some studies suggest that HOXC6 might be involved in tumor initiation and progression.However, the role of HOXC6 in esophageal squamous cell carcinoma cells has not been fully investigated.Here we study how HOXC6 affects the malignant phenotype of esophageal squamous cell carcinoma cells

Project description:Investigation of whole genome gene expression level changes in Homo sapiens Esophageal squamous cell carcinoma cells KYSE30 after knock down of MTA2 gene expression
Project description:Copy number analysis of primary esophageal squamous cell carcinoma (ESCC) from 40 patients in Japan. Integrative analysis of gene expression profiles and genomic alterations obtained from array-CGH and NGS provided us new insight into the pathogenesis of ESCC.
Project description:Both genetic and epigenetic aberrations are linked by intricate crosstalk, and can either individually or in synergy lead to the development of cancer. Accumulating evidence suggests that epigenetic changes such as alterations in DNA methylation play a crucial role in ESCC. We performed a Illumina Infinium HumanMethylation450 BeadChip to examine the global methylation signature of esophageal squamous cell carcinoma of Chinese patients. DNA methylation profiles of esophageal squamous cell carcinoma (4 samples), paired adjacent normal surrounding tissues (4 samples) and normal esophagus mucosa from healthy individuals (4 samples) were generated using Infinium methylation 450K BeadChips from Illumina (Illumina, San Diego, USA).
