Although this is the first report of the existence of an inverse correlation between cellular levels of miR-29c and WIP1, the downregulation of miR-29c has been found in medulloblastoma [57], glioma [58] and gastric cancer [59]; however, the upregulation of WIP1 has also been reported in these carcinomas [60–62], implicating a possible inverse correlation between these two molecules. This evidence concerns the gene PPM1D and gastric cancer.
