Afterwards, we examined the expression of PHF5A according to N staging and discovered a significant association of lymph node metastasis with PHF5A expression in 6 types of cancer: ACC, COAD, Colon adenocarcinoma/Rectum adenocarcinoma esophageal carcinoma (COADREAD), HNSC, LUAD, and Stomach and esophageal carcinoma (STES) (Fig. 2D). The gene discussed is PHF5A; the disease is carcinoma of esophagus.
