Their regulation has been implicated in the pathogenesis of a number of human pathologies including cancers. In the present work, we aimed to investigate expression profiles of micro-RNA (miRNA) in patients with Medulloblastoma cancer, which is the most common type of primary brain cancer in children. It starts in the lower back part of the brain, called the cerebellum which is involved in muscle coordination, balance and movement. . The number of methods and softwares for differential expression analysis from RNA-Seq data increased rapidly. In this comparative study, we identified and analysed Human sex-biased Micro-RNAs in infants by examining a transcriptome dataset of patients with Medulloblastoma. This was done using RSubread as a tool for mapping and its command “featurescounts” to quantify the miRNAs, and DESeq2 bioinformatics package to conduct a differential analysis of miRNAs between infant males and females. Consequently, 147 miRNAs were found differentially expressed with different abundances between the sexes.The results further highlight the applicability of miRNA expression patterns as potential markers of human Medulloblastoma cancer and most probably other cancers in children. | | Numéro (Thèse ou Mémoire) : | MM0372020 | | Président : | Azeddine IBRAHIMI | | Directeur : | Hassan GHAZAL | | Juge : | Mustapha CHAMEKH | | Juge : | Said BARRIJAL | | Juge : | Chohra TALBI |
