For instances, PANDAR promotes cell proliferation and suppresses cell apoptosis in pancreatic ductal adenocarcinoma (Jiang et al., 2017); inhibition of PANDAR reduces cell proliferation and cell invasion and suppresses EMT process in breast cancer (Li et al., 2019); PANDAR blocks CDKN1A gene transcription via competitive interaction with p53 protein in gastric cancer (Liu et al., 2018); SP1-induced PANDAR regulates cell growth and apoptosis of retinoblastoma cells (Sheng et al., 2018). Here, SP1 is linked to pancreatic ductal adenocarcinoma.
