ABAT and familial pancreatic carcinoma: Analysis of genes involved in BCAA catabolism in pancreatic cancer showed that among dihydrolipoamide branched chain transacylase E2 (DBT), 4-aminobutyrate aminotransferase (ABAT), acetyl-CoA acetyltransferase 1 (ACAT1), BCAT1, and BCAT2, which were correlated to poor prognosis, ABAT and BCAT2 were hub genes with satisfactory prognosis values.
