TCF3 and acute lymphoblastic leukemia: These findings could explain our results regarding the reduced OS observed in BCP-ALL cases carrying TCF3/PBX1 and displaying underexpression of LINC00173. Furthermore, we discovered that the BCR/ABL1 molecular subtype expressed the highest levels of LINC00173. According to these data, we observed that LINC00173 is highly expressed in the K562 cell line (BCR/ABL1-positive); furthermore, a high expression of LINC00173 has also been reported in the Philadelphia chromosome-like (Ph-like) subtype (59).
