Two LSC samples (ALDH+ H1975 LUAD tumor cells (LSC1-m) and ALDH+ H1975 LUAD tumor cells (LSC2-m)) and two LTC samples (ALDH-H1975 LUAD tumor cell (LTC1-m) and ALDH-H1975 LUAD tumor cells (LTC2-m)) were obtained as described in our previous study [11]. This evidence concerns the gene LDHA and neoplasm.
