Also, PODNL1 expressions were found to be positively correlated with the expression levels of cancer stem cell-related molecular markers as cluster of differentiation 44 (CD44), sex-determining region Y-box transcription factor 2 (SOX2), spalt-like transcription factor 1 (SALL1), RNA exonuclease 1 homolog (REXO1), nucleus accumbens-associated protein 1 (NACC1), cyclin D1 (CCND1), catenin beta-1 (CTNNB1), neurogenic locus notch homolog protein 1 (NOTCH1), NOTCH4, and nestin (NES) in more than 10 types of cancers, especially with the NES in more than 20 types of cancers (Figure 6G). This evidence concerns the gene NACC1 and cancer.
