PCAT1 and gastric adenocarcinoma: By expanding our analysis on other cancer types from TCGA database, we found that although PiHL was also upregulated in cancer types other than CRC, like stomach adenocarcinoma (STAD), cholangiocarcinoma (CHOL), bladder carcinoma (BLCA) and liver hepatocellular carcinoma (LIHC), correlation between PiHL copy number and p53/TP53 was not observed in these cancer types (Figure S2D).
