SALL1 and cancer: 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).
