Bioinformatics based identification of potential microRNA biomarkers in frequent and non frequent exacerbators of COPD

PMCID: 5909781
PMID: 29713155
DOI: 10.2147/COPD.S163459

[…] tivity by handling the various types of data and performing multiple testing corrections on P-values.The accuracy for the predicted targets of candidate miRNAs was improved by the following software: PicTar, miRDB and TargetScan. Validated targets were acquired from TarBase. Briefly, we took the intersection of the three series of predicted targets and validated the targets using TarBase. […]


Salivary microRNAs as new molecular markers in cleft lip and palate: a new frontier in molecular medicine

PMCID: 5922367
PMID: 29721173
DOI: 10.18632/oncotarget.24838

[…] e different miRNA set expression in the two study populations see also the heat map shown in Figure . Moreover, we analyzed the results using the TargetScan program http://www.targetscan.org/, http://pictar.mdc-berlin.de/, http://www.microrna.org/microrna/home.do) that contain the miR-binding site(s) in the UTR. TargetScan analysis predicted the binding of miR-324-3p e miR-223 to the 3′-UTR of met […]


Tumor suppressor role of miR 139 5p in endometrial cancer

PMCID: 5879796
PMID: 29618950
DOI: 10.1186/s12935-018-0545-8

[…] mediated by p21 []. However, the regulatory mechanisms that underlie the expression of HOXA10 in EC have yet to be studied. We predicted that miR-139-5p, is a regulator of HOXA10 expression, based on PicTar, TargetScan, and miRBase database. However, the role of miR-139-5p in EC development, especially regarding its link with HOXA10, has not been explored yet. In the present study, we investigated […]


Inhibition of breast cancer metastasis by co transfection of miR 31/193b mimics

PMCID: 5960762
PMID: 29796229
DOI: 10.22038/IJBMS.2018.26614.6522

[…] 6.2gw/ EmGFP vector. To identify potential target genes of miR-193b and miR-31, the TargetScan (http://www.targetscan.org), miRanda (http://www.microrna.org), miRDB (http://www.mirdb.org/miRDB/) and PicTar (http://pictar.mdc-berlin.de) databases were used. […]


MicroRNA 671 3p inhibits the development of breast cancer: A study based on in vitro experiments, in house quantitative polymerase chain reaction and bioinformatics analysis

PMCID: 5919715
PMID: 29620195
DOI: 10.3892/ijo.2018.4339
call_split See protocol

[…] ted target genes of miR-671-3p were determined using the miRWalk 2.0 database (zmf.umm.uni-heidelberg.de/apps/zmf/mirwalk2), which contains 12 online tools, namely Targetscan, RNAhybrid, RNA22, PITA, Pictar2, miRWalk, Microt4, miRNAMap, miRDB, mirbridge, miRanda and miRMap. Targets predicted by >3 algorithms were selected for GO functional annotation and KEGG pathway analyses using the DAVID onlin […]


Integrative proteomics in prostate cancer uncovers robustness against genomic and transcriptomic aberrations during disease progression

Nat Commun

[…] eter values: Input parameters Promoter 2 kb, 3′ UTR, minimum seed length 7 and/or p-value 0.05. We considered mRNA to be a target for miRNA if targeting was predicted by 2/3 of the databases miRanda, PICTAR2, and Targetscan–. Differentially expressed miRNAs were defined as having an absolute median ratio between two conditions >1.5, and the Benjamini-Hochberg adjusted p-value of a non-parametric W […]
