To identify potential molecules to regulate the stemness from RPL10 ufmylation, we chose four well-known stemness related transcription factors, including KLF4, Nanog, Oct4 and SOX-2, to analyze the correlation between these transcription factors and RPL10 or UFM1 in the tissues of PAAD patients (http://gepia2.cancer-pku.cn/#correlation). The gene discussed is KLF4; the disease is pancreatic adenocarcinoma.
