SAP30 promotes clear cell renal cell carcinoma proliferation and inhibits apoptosis through the MT1G axis.

ABSTRACT: Sin3A-associated protein 30 (SAP30) is a crucial component of the SIN/HDAC histone deacetylase complex and acts as a scaffold that facilitates target gene binding. SAP30 is highly expressed in various tumours; however, its role in renal cell carcinoma (RCC) remains unclear. In our study, we observed the upregulation of SAP30 in clear cell renal cell carcinoma (ccRCC) tissues, and its elevated expression was correlated with a poor prognosis. Previous research has suggested that SAP30 may influence the growth, proliferation, and apoptosis of RCC cells. Gene Ontology (GO) analysis of the downstream regulatory targets of SAP30 revealed that SAP30 suppressed the expression of MT1G, a protein that binds to p53. Mechanistically, SAP30 inhibited MT1G transcription, thereby impairing the function o
