HOXA10 and colonic neoplasm: The predominance of transcription factors across right-sided clusters (HOXC6, HOXA10-HOXA9, HOXB6) aligns with the developmental reprogramming characteristic of proximal colon tumors, while the enrichment of regeneration-associated genes (REG1A, REG4) reflects the tissue repair pathways activated in right-sided malignancies.
