Conversely, Eno1, a glycolytic enzyme with antiapoptotic activity [30], Ctla2a, a selective inhibitor of cathepsin L-like cysteine proteinases highly expressed in germline and hematopoietic stem cells [31,32], and Pkm, a phosphotyrosine-binding protein involved in glycolysis, were found only in LH and CIS + LH, implying an induction by LH possibly favoring the ovarian tissue maintenance, not hindered by CIS. This evidence concerns the gene ENO1 and in situ carcinoma.
