HOXD10 and cancer: Mainly, in the first group, we have genes with a suggested novel anti-cancer role in the testis (Fetub, Hoxd10, Slc45a3, Ube2l6), with increased expression levels inhibiting cancer cell development, supported by the protective role of Mt3; while the Usp39 gene, with elevated expression levels (the most of all the observed changes), should lead to some tumor-like changes within the testis tissue.
