Novel Insights into DOCK4 as a Tumor Suppressor and Biomarker in Lung Cancer: Comprehensive Bioinformatics Analysis of LUAD and LUSC

Overview

This study investigates the Dedicator of Cytokinesis 4 (DOCK4) gene as a potential tumor suppressor and diagnostic biomarker in lung adenocarcinoma (LUAD) and lung squamous cell carcinoma (LUSC) using a comprehensive bioinformatics approach. By integrating multi-omics data from TCGA and other public databases, the project analyzes DOCK4 expression, mutation frequency, methylation status, and its association with patient survival. Functional enrichment, immune infiltration analysis, and co-expression networks are used to reveal the biological role of DOCK4 in lung cancer progression.

Objectives

Assess DOCK4 expression levels in LUAD and LUSC compared to normal lung tissues.
Analyze the prognostic significance of DOCK4 expression in patient survival and disease outcomes.
Explore mutation and methylation patterns of DOCK4 in lung cancer subtypes.
Perform pathway enrichment and gene co-expression analyses to understand DOCK4-related signaling networks.
Investigate the relationship between DOCK4 and immune cell infiltration to explore its potential role in tumor immunology.
Propose DOCK4 as a candidate biomarker for diagnosis, prognosis, or therapeutic targeting in lung cancer.

"At first, I didn’t know anything about bioinformatics. By chance, I heard about the MSc in Bioscience at the National University (Medicine School), and we became the first batch. It turned out to be a great opportunity for me. I learned how to map, analyse, and handle genome sequencing to identify the causes of diseases—bacteria, viruses 🦠—especially those related to my field of dentistry. I gained practical laboratory experience 🧪🧫, learning how to handle and extract DNA. We were also visited multiple times by renowned lecturers from South Africa, who showed us how fast the field of bioinformatics is growing and how reliable it is for applications such as coronavirus outbreak analysis and vaccine development. Today, I have my name on three published papers in different medical fields—something I never imagined I could achieve. My sincere thanks 🙏 to the National University and the Institute of Bioscience for this opportunity"

"I am Mohamed Jaafar Mohamed, one of the graduates of the Master's program in Bioinformatics at the National University. My experience began about two years before the start of the master’s program, when the university organized the first Bioinformatics workshop using Galaxy in Sudan. The workshop was successful and inspiring in both concept and execution, attracting many participants. From that moment, the idea of bioinformatics started to grow in my mind. When the admission for the second cohort opened, I was among the first to register. After waiting for nearly a year, the study period began. Although we faced several challenges — including political unrest and revolutions that often led to the postponement of lectures due to circumstances beyond the administration’s control — the institute’s management handled these difficulties wisely. The courses were well-designed, the professors were highly qualified, and a fully equipped laboratory with modern devices was made available to students. Despite all challenges, we successfully completed the study period. Then came the stage of research publication, which became even more difficult after the outbreak of war in Sudan. However, thanks to the continuous efforts and communication between the supervisors, administrative staff, and students — each in their respective locations — we were able to complete this wonderful journey. Despite the harsh conditions, the academic and scientific benefits we gained were invaluable. The program opened many doors for us in the professional field and enhanced our competitiveness even beyond Sudan"
