The results from IHC performed on 61 OSCC tissues using ACAT1 antibody showed that ACAT1 is variably expressed among OSCC tumours, with high ACAT1 protein expression in 23 of 61 patients (37.7%) and low ACAT1 protein expression in 38 of 61 patients (62.3%). The gene discussed is ACAT1; the disease is neoplasm.
