Upregulated miRs in gastric cancer, a story still to be told

Dear Editor, Following the publication of our preliminary investigation on down-regulated miRs in gastric cancers , we completed the analyses focusing on the 4 upregulated miRs (miR21, miR135b, miR196a, miR196b) on the same cohort of 117 non-cardial gastric cancer patients. The investigation was carried with the same identical experimental design and statistical analyses, as previously described.
