Elevated PBX3 tumor expression has been found to be associated with a number of key clinical and pathological indicators associated with a poor outcome in gastric cancer, including invasion depth, and the stage and grad e of the tumor [47,48], and, correspondingly, tumor expression of miR-144-3p, which blocks PBX3 expression at the post-transcriptional level, is negatively correlated with tumor stage, invasion depth, and nodal metastasis [30]. Here, PBX3 is linked to gastric cancer.
