Abstract Background The use of sex-sorted sperm in cattle assisted reproduction is constantly increasing. However, fertility can substantially differ between unsorted (conventional) and semen batches the same sire. Sperm microRNAs (miRNA) have been suggested as promising biomarkers bull last years. In this study, we hypothesized that miRNA profile cryopreserved conventional related to after art...

micrornas (mirnas) are a class of small non coding regulatory rnas that have key functions in multiple cell processes. deregulation of these tiny mirnas are involved in various human diseases. mir-155 is one of the multifunctional mirna that its over-expression has been found to be associated with different kinds of cancer such as leukemia, breast and colon cancers. it is thought that deregulat...

Objective(s): Autophagy-related 4B (ATG4B) plays an important role in the process of autophagy induction. However, the molecular events that govern the expression of ATG4B in this process are not well known. Materials and Methods: Human ATG4B 3'-UTR region (1377 nt) containing miR-34a/miR-34c-5p binding site was amplified by PCR. Luciferase assay was used to assess the activity of reporter gene...

Objective(s):MicroRNAs (miRNAs) are a class of short RNAs that control the biological processes including cell proliferation, apoptosis and development. Aberrant expression of miRNAs was determined in the different stages of tumor development and metastasis. To study the effect of silibinin on miRNAs expression, we evaluated quantitative expression of miR-21 and miR-155 as two oncomiRs and seve...

In the last decade, numerous microRNAs (miRNAs) have been identified in diverse virus families, particularly in herpesviruses. Gallid alphaherpesvirus 2 (GaHV2) is a representative oncogenic alphaherpesvirus that induces rapid-onset T-cell lymphomas in its natural hosts, namely Marek's disease (MD). In the GaHV2 genome there are 26 mature miRNAs derived from 14 precursors assembled into three c...

Cancer is a complex disease process that evolves as a consequence of multiple malfunctions in key regulatory molecular networks. Understanding these networks will be essential to combat cancer. In this study, we focussed on central players in such networks. In a series of colon and breast cancer cell lines, we found that CD24 activates Src, and induces the activation of c-Jun and expression of ...
