Within these, several regulators have been demonstrated to be involved in various disease processes, such as miR-370-3p (cholangiocarcinoma, [71], acute myeloid leukemia [72], oral squamous carcinoma [73], hepatocellular carcinoma [74], ovarian cancer [74]), miR-143 (DE between the duodenum of E. coli F18 -sensitive and resistant weaned piglets [75]), miR-133 (acute myocardial infarction [76], breast cancer [77]), and MAPK9 (production of inflammation mediator [78]). This evidence concerns the gene MAPK9 and breast cancer.
