They could be proposed as tumor-promoters since they were found to be more-abundant proteins either in the superficial region, such as WDR5, or in the deep area of the tumor, such as X-ray repair cross complementary 1 (XRCC1), NASP, heterogeneous nuclear ribonucleoprotein D-like (hnRNP D-like), histone H3.3, EF-2, and RNA-binding protein 34. This evidence concerns the gene XRCC1 and neoplasm.
