DBNDD1 (dysbindin domain containing 1) is a conserved eukaryotic protein with an intrinsically disordered structure 1. While its precise molecular mechanisms remain poorly characterized, emerging evidence implicates DBNDD1 in signal transduction regulation and cancer pathogenesis. In colorectal cancer, DBNDD1 functions as a key driver of disease progression through a synergistic signaling pathway. DBNDD1 promotes GDF15 induction, which activates NF-κB/RELA signaling to enhance cancer cell proliferation, migration, and invasion 2. DBNDD1 knockdown inhibits these malignant phenotypes in vitro and reduces tumor growth in vivo 2. Higher DBNDD1 expression correlates with worse overall survival in colorectal cancer patients 2. Machine learning models identify DBNDD1 as one of the top predictive genes for colorectal cancer diagnosis 3. Beyond colorectal cancer, DBNDD1 is associated with melanoma susceptibility as a genome-wide significant locus 4. In prostate cancer, upregulated DBNDD1 correlates with cell cycle and mitotic pathways, while its expression associates with immunosuppressive immune infiltration patterns (elevated MDSCs, M2 macrophages; reduced CD8+ T cells, M1 macrophages) 5. DBNDD1 was additionally identified as a feature gene in keratoconus, a corneal disease 6. These findings position DBNDD1 as a promising therapeutic target for precision medicine approaches in multiple cancer types.
