Identification of MAPK12 as a Prognostic Biomarker for Esophageal Carcinoma Using Bioinformatics and Machine Learning

Area of Science:

• Oncology
• Bioinformatics
• Genomics

Background:

• Esophageal carcinoma (ESCA) poses a significant global health challenge.
• Accurate prognostic markers are crucial for effective ESCA patient management.
• Telomere dysfunction is implicated in various cancers, including ESCA.

Purpose of the Study:

• To develop a novel telomere-related prognostic signature for esophageal carcinoma (ESCA).
• To identify key genes and pathways involved in ESCA progression.
• To validate the prognostic model and explore therapeutic targets.

Main Methods:

• Integration of bioinformatics and machine learning techniques.
• Identification of differentially expressed genes (DEGs) and hub genes.
• Construction and validation of a prognostic model using LASSO and Cox regression.
• Experimental verification including cytological assays.

Main Results:

• A robust telomere-related prognostic signature for ESCA was developed.
• The model demonstrated significant predictive power for patient survival in independent datasets.
• Mitogen-activated protein kinase 12 (MAPK12) was identified as a key driver of ESCA cell migration.

Conclusions:

• The developed prognostic model offers a reliable tool for predicting ESCA patient outcomes.
• MAPK12 emerges as a potential diagnostic biomarker and therapeutic target for ESCA.
• This research provides a foundation for understanding ESCA pathogenesis and developing targeted therapies.
