We assessed the regulators of PAFAH1B3 in HCC by analyzing the enrichment of kinases, miRNAs, and transcription factors (TF) of PAFAH1B3 positively related genes and found that PAFAH1B3 was primarily related to the CDK1 and PLK1 kinases in HCC (Supplement Table 1). Here, PLK1 is linked to hepatocellular carcinoma.
