Abstract
OBJECTIVES: Cancer is a threat to human health, and many molecules are involved in the transformation of malignant cells. Hepatocyte nuclear factor 1A (HNF1A) is an important transcription factor that regulates multiple biological processes. Our research focused on elucidating the expression and function of HNF1A in cancer through bioinformatic analysis. METHODS: UALCAN, Kaplan-Meier plotter, COSMIC, Tumor IMmune Estimation Resource, and Cancer Regulome were used to obtain relevant data for HNF1A. RESULTS: HNF1A was abnormally expressed in multiple cancers, and its expression was associated with differences in overall survival in patients with cancer. HNF1A mutations widely exist in tumors and interact with different genes involved in various processes. Additionally, we found that HNF1A was associated with the infiltration of immune cells, and it affected the prognostic value of these cells in some cancers. CONCLUSIONS: HNF1A plays a crucial role in cancer, and it may represent a biomarker and target for future cancer immunotherapy.
