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 |
miR222 | microRNA 222 | miR221 and miR222 downregulate PTEN, a major tumor suppressor and TIMP3, which induces activation of caspases 8 and 9 [19962668]. Thus miR221 and miR222 enhance tumorigenecity in cell lung cancer, gastric cancer and hepatocarcinoma cells [20618998]. | Human |

MIR217 | microRNA 217 | MIR217 (alias hsa-miR-217) is significantly upregulated in senescent human mesenchymal stem cells (hMSCs) when compared to early passage hMSC, but overall had very low expression levels [18493317]. | Human |
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 |
MIR15A | microRNA 15a | MIR15A is a tumor-suppressor downregulated in different types of cancers. In chronic lymphocytic leukemia (CLL) it is downregulated in 68% of cases [12434020]. MIR15A may post-transcriptionally downregulate the expression of Bcl2, thus inducing apoptosis. Therefore, inactivation of MIR15A and MIR16-1 in CLL lymphocytes results in a reduced apoptosis rate [16166262].
In prostate cancer, MIR15A and MIR16-1 are downregulated, which results in decreased repression of FGF-2, thus promoting tumor expansion and invasiveness [21532615].
MIR15A and MIR16-1 are also downregulated in pituitary adenomas as thier expression exhibits an inverse correlation with tumor diameter, therefore possible influence on tumor growth [15648093]. | Human |
miR152 | microRNA 152 | MiR152 belongs to miR148/152 cluster and can act as a tumor-suppressor. In ovarian cancer, miR152 suppresses DNMT1 directly and inhibits proliferation of cancer cells. [23318422] The miRNA is downregulated in ovarian cancer cells lines and its downregulation may lead to deregulation of cell proliferation in ovarian cancer. [21971665]
| Human |
miR148a | microRNA 148a | miR148a belongs to miR148-152 cluster and acts as a tumor-suppressor in different types of cancer. MiR148a expression is suppressed more than 4-fold in gastric cancer. An inverse correlation has been observed between miR148a expression and lymph node metastasis in gastric cancer. Mir148a suppresses migratory abilities of cancer cells and metastasis formation by downregulating the oncogene ROCK1 expression [21994419]. miR148a is downregulated in pancreatic ductal adenocarcinoma (PDAC). it has been shown that miR148a directly targets the 3'UTR region of CDC25B mRNA. CDC25B is a phosphatase that, by activating a cyclin-CDK complex, initiates mitosis, therefore CDC25B suppression by miR148a could have a tumor-suppressor effect on PDAC. [21709669] | Human |
MIR145 | microRNA 145 | MIR145 is a tumor suppressor that acts by inhibiting IRS-1 in human colon cancer cells. It also targets IGFR1 [17827156; 19391107]. It decreases cell migration in gliomas by targeting CTGF, metastasis and migration-promoting gene. MIR145 is downregulated in astrocytic tumors and oligodendrogliomas [23390502;
23577178]. | Human |
MIR106A | microRNA 106A | MIR106A is downregulated in senescent cells as it has a good correlation with p21 transcription, while p53 represses mir17-92 cluster [20437201; 20089119]. | Human |

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 |

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].
| Human |
MIR155 | microRNA 155 | mir-155 is significantly overexpressed in human breast cancer while targeting the miRNA could induce apoptosis and cell cycle arrest as well as inhibit cell growth. [18719391]. Mir155 acts by repressing socs1, a tumor suppressor. In addition, inflammatory signals may activate miR155, thus suggesting that the miRNA serves as a link between inflammation and malignancy formation [20354188]. It is also upregulated in lung cancer and acts an oncogene by targeting Apaf1 and thus reducing apoptosis rate [22996741]. Inhibition of mir-155 radiosensitizes cancer cells [22027557]. | Human |
MIR146B | microRNA 146b | miR-146a/b is significantly elevated during senescence as a compensatory response to restrain inflammation via the suppression of IL-6 and IL-8 secretion and downregulation of IRAK1 (component of IL-1 receptor signaling).
