MIR27A | microRNA 27a | MIR27A can be both a tumor-suppressor and an oncogene. For instance, the expression of miR-27a is significantly lower in acute leukemia compared to normal cells. It has been shown that miRNA-27a inhibits cell growth and promotes apoptosis by targeting 14-3-3θ, a member of 14-3-3 family of anti-apoptotic proteins. [23236401]. Therefore, it acts as a tumor-suppressor in leukemia. However, in gastric cancer mir-27a acts as an oncogene by targeting inhibiting and thus promoting cancer cell growth [18789835]. | Human |
MIR29A | microRNA 29a | miR-29a reduces the amount of methylation and upregulates a long non-coding RNA form a region called MEG3 that is responsible for inducing apoptotic pathway. Thus reducing tumorgensis in non-malignant hepatocytes [21625215].

MIRC29 | microRNA 29c | hsa-miR-29c is significantly upregulated in senescent human mesenchymal stem cells (hMSCs) when compared to early passage hMSC [18493317]. | Human |
MIR34A | microRNA 34a | mir-34 family, particularly miR-34a, as downstream effectors of p53 involved in cell cycle [17656095], leads to cell cycle arrest, increased expression of Beta-galactosidase [17554337] and downregulation of E3F family target genes [17875987]. MDM2 inhibiting drug Nutlin-3, leads to p53 activation, induced up-regulation of primarily miR-34a and later miR-34b and miR-34c [18451145]. | Human |
MIR34B | microRNA 34b | mir-34 family, particularly miR-34a, as downstream effectors of p53 involved in cell cycle [17656095], leads to cell cycle arrest, increased expression of Beta-galactosidase [17554337] and downregulation of E3F family target genes [17875987]. MDM2 inhibiting drug Nutlin-3, leads to p53 activation, induced up-regulation of primarily miR-34a and later miR-34b and miR-34c [18451145]. | Human |
MIR34C | microRNA 34c | — | Human |
MIR369 | microRNA 369 | hsa-miR-369-5p is significantly upregulated in senescent human mesenchymal stem cells (hMSCs) when compared to early passage hMSC [18493317]. | Human |
MIR371A | microRNA 371a | hsa-miR-371 is significantly upregulated in senescent human mesenchymal stem cells (hMSCs) when compared to early passage hMSC [18493317]. | Human |
MIR372 | microRNA 372 | miR-372 expression is able to bypass RAS-induced senescence in presence of wild-type p53 [16564011]. | Human |

Mir669c | microRNA 669c | Expression increases with age in mouse liver. The miRNA downregulates detoxification and regeneration genes, which may contribute to aging [18561983]. | House mouse |
hsa-let-7a | microRNA let-7a | A tumor-suppressor downregulated in different types of cancer. Let-7a binds to 3'-UTR region of RAB40C, thus leading to a decrease in cell proliferation and an increase of G1 arrest in human gastric carcinomas [20809749, 21349817]. In human breast cancer, evidence suggests that members of let-7 family inhibit breast cancer cell migration by targeting genes responsible for actin dynamics [23339187]. Moreover, let-7a directly targets CCR7, a receptor that promotes invasiveness of cancer cells [23335963] | Human |
hsa-let-7b | microRNA let-7b | Let-7b, a member of the let-7 group, appears to be a tumor-suppressor. In acute lymphoblastic leukemia, let-7b is severely downregulated and its overexpression inhibits cancer cells growth [22918121]. In melanoma cells, the miRNA downregulates the expression of cell cycle regulators such as cyclin D1, D3, and A and Cdk4, which inhibits cell cycle progression. [18379589] | Human |
hsa-let-7c | microRNA let-7c | let-7c is downregulated in prostate cancer, which increases cell proliferation [22479342]. More specifically, let-7c is a regulator of androgen receptor (AR), which plays a role in the development of prostate cancer [22128178]. | Human |

mir-14 | mir-14 stem loop | Mutating mir-14 decreases lifespan in both sexes. mir-14 reduces the mean and maximum lifespan of females by 55 and 36%, respectively, while those of males is reduced by 29 and 21%, respectively [12725740].

MIR21 | MIRN21; hsa-mir-21; miR-21; miRNA21 | MIR21 is the most highly expressed microRNA gene in octogenarians and centenarians. MIR21 expression is higher under cardiovascular diseases and lower in centenarian offspring. MIR21 is correlated with C-reactive protein and fibrinogen levels. TGF-βR2 mRNA, a MIR21 target, exhibits the highest expression in leukocytes form a subset of octogenarians. MIR-21 may be a biomarker of inflammation [23041385]. | Human |
