Unveiling the enigmatic role of MTBP in pan-cancer: A bioinformatics perspective

The role of MDM Two Binding Protein (MTBP) in tumor regulation is controversial; METHODS: We gathered MTBP's genomic location and GTEx expression data from University of California Santa Cruz (UCSC) and utilized the Human Protein Atlas (HPA) to evaluate its expression. Survival prognosis and immune infiltration analysis were meticulously evaluated by downloading and processing TCGA RNAseq data. Genetic alterations in MTBP were explored using cBioPortal; (3) Our findings revealed a prevailing trend of MTBP overexpression in numerous cancer types, associating with adverse prognoses and implicating MTBP as an oncogenic facilitator. Notably, in certain cancers, reduced MTBP expression correlated with improved patient survival, reflecting a tumor suppressive function of MTBP. By analyzing the tumor immunological environment, we observed positive correlations between MTBP and specific T helper cell subsets, suggesting its potential role in immune evasion strategies. Phosphorylation emerged as a pivotal post-translational modification regulating MTBP's function, influencing DNA replication process frequently exploited by cancer cells. Functional enrichment analyses highlighted MTBP's involvement in nuclear division, organelle fission, and cell cycle regulation, reinforcing its centrality in tumor proliferation and differentiation; CONCLUSIONS: Our results position MTBP as a critical regulator of cancer progression, with implications for immune modulation and DNA replication control.
