SLC9A1 and neoplasm: The resistance to genotoxic attack by CD45−/−lckF505 murine tumour cells correlates, as in their pretumourigenic counterparts, with the inhibition of DNA damage–induced NHE-1 antiport expression, alkalinisation, Bcl-xL deamidation, and apoptosis (Figure S7), which is an apparent example of ”oncogene addiction”, whereby oncogene expression continues to be important for survival [36].
