DHX34 and neoplasm: In addition, the high expression results of these cancer types in TCGA data are particularly significant, suggesting that DHX34 may play an important role in their development, which is worthy of further clinical validation; Considering the depth and breadth of the study and the limited resources, it is reasonable to selectively focus on those cancer types with the most significant high expression trend and prognostic value; Although the current study focused on four cancer types, COAD, LIHC, LUAD, and STAD, we also recognize that DHX34 may be equally important in other tumor types.
