Glycerol kinase enzyme is a prognostic predictor in esophageal carcinoma and is associated with immune cell...

Area of Science:

• Oncology
• Molecular Biology
• Cancer Metabolism

Background:

• Lipid metabolism significantly impacts cancer development and progression.
• The specific role of Glycerol Kinase (GK), a key glycerol metabolism enzyme, in Esophageal Carcinoma (ESCA) is not well understood.

Purpose of the Study:

• To investigate the expression levels and clinical significance of Glycerol Kinase (GK) in Esophageal Carcinoma (ESCA).
• To determine the correlation between GK expression, patient prognosis, and immune infiltration in ESCA.

Main Methods:

• Analysis of publicly available database information (The Cancer Genome Atlas - TCGA).
• Immunohistochemistry (IHC) on clinical ESCA tumor and normal tissue samples.
• Kaplan-Meier (KM) survival analysis and multiple regression analysis for prognostic assessment.

Main Results:

• GK expression was significantly elevated in ESCA tissues compared to normal tissues.
• Higher GK expression correlated with poorer overall survival (OS) and disease-specific survival (DSS) in ESCA patients.
• Elevated GK expression was identified as an independent risk factor for ESCA prognosis and showed a correlation with immune cell infiltration (T and B lymphocytes).

Conclusions:

• Elevated Glycerol Kinase (GK) expression is a significant indicator of poor prognosis in Esophageal Carcinoma (ESCA).
• GK may serve as an independent prognostic biomarker for ESCA.
• The findings suggest GK as a potential therapeutic target for managing Esophageal Carcinoma.
