miRNAs generated from Meg3-Mirg locus are downregulated during aging

Genes upregulated in aging which are targeted by miRNAs from Meg3-Mirg locus. (A) Venn diagram illustrating the predicted targets of the 27 downregulated miRNAs. Three databases were interrogated and the overlapping targets were further used for pathway enrichment analysis, which identified 347 unique genes. (B) Graphical illustration of the intersection between the unique genes found in KEGG pathway and the upregulated genes identified in Tabula Muris Senis database. The upregulated genes are highlighted in each organ. Itgb2 emerged as the only gene upregulated in 4 out of 6 organs. (C) Illustration of the recognition sites of miRNAs from the locus targeting the 3`UTR region of Itgb2 mRNA. (D) The expression of the Itgb2 in the brain, ventricle, kidney, liver and cultured cardiac fibroblasts. For each organ, the expression is presented relative to the young group. Two-tailed two-samples T-test for equal or unequal variances; Wilcoxon two-sample test for non-normal distribution; * p
