Unveiling the Mystery of SUMO-activating enzyme subunit 1: A Groundbreaking Biomarker in the Early Detection and Advancement of Hepatocellular Carcinoma.

Hepatocellular carcinoma (HCC) is one of the leading causes of cancer-related deaths worldwide. The discovery and research of effective biomarkers have become prevailing trends. SUMO-activating enzyme subunit 1 (sae1), an E1-activating enzyme, is indispensable for protein SUMOylation. In this study, we conducted a comprehensive analysis of database contents and found that sae1 is highly expressed in HCC and is correlated with poor prognosis. We also identified its regulated transcription factor, rad51, and related signaling pathways. We conclude that sae1 is a promising cancer metabolic biomarker with diagnostic and prognostic value in HCC.
