In addition, HFFF2TERT-HA displayed a shift towards the glycolytic metabolism, similar to the Warburg effect observed in tumor cells [35], as shown by the analysis of the glyco- and mitoATP production; hence, a reduction in the expression of proteins involved in OXPHOS, such as ND1 and ND3 subunits of complex I, is predictable. This evidence concerns the gene MT-ND3 and neoplasm.
