Chi-miR-4110 promotes granulosa cell apoptosis by targeting Sma- and Mad-related protein 2 (Smad2) in the caprine ovary.

follicular atresia primarily a result of apoptosis of granulosa cells (GCs). While our previous investigations examining the role of chi-mir-4110 to regulate ovarian function, this study detected the role of chi-miR-4110 in the development of GC. We transfected caprine GCs cultured in vitro with chi-mir-4110 imitate. The results showed that the chi-mir-4110 Fungal Recombinant Proteins decreases Smad2 mRNA and protein level by targeting the 3'-translated region of its (3'UTR). 

FoxC1 and Sp1 mRNA and protein levels increased sharply, while that of bHLHe22 decreased significantly (P <0.01 or 0.05) in GCS transfected with miR-4110 chi emulate. Further research revealed significantly higher number of apoptotic cells in GCS transfected with miR-4110 chi mimic (P <0.05) than GCS transfected by mimicking the negative control. GCS transfected with miR-4110 chi mimic exhibited significantly increased mRNA and protein levels of pro-apoptotic Bax gene (P <0.01) and significantly reduce the level of gene expression of anti-apoptotic BCL-2 (P <0.01). 

Smad2 disorder (Si 1282) results are consistent with those of chi-mir-4110 imitate. previous reports and our results show that the expression of chi-miR-4110 increasing by repressing Smad2 Sp1. Increased Sp1 induces p53-upregulated modulator of apoptosis, which increases the relative abundance of Bax and caprine GC cause apoptosis. Our findings can provide relevant data for the investigation of miRNA-mediated regulation of ovarian function.

A panel of protein candidates for the comprehensive study of caprine arthritis encephalitis (CAE) infection.

The caprine arthrite encephalite (CAE) is a disease that affects mainly goats milk. Virus showed compartmentalization features, which allows it to hide at any given time during the course of the disease, making it difficult to control. This study was conducted to identify the major seminal plasma protein profile of goats infected with CAE and associated with seroconversion using Western blotting. 

Two groups containing five men each, were used in this study. The first group is composed by animals seropositive and seronegative controls Hapten Conjugates Proteins   were confirmed by Western blotting and PCR. The semen was collected via artificial vagina and after that, the two-dimensional electrophoresis and MALDI-TOF MS is used.

 Seventy-five places identified goat seminal plasma gel, equivalent to 13 different proteins with more expression. Similar proteins found in both groups and is associated with reproductive spermadhesin Z13-like, bodhesin and bodhesin-2, lipocalin, protein PDC-109-like, and albumin. In the infected goats, proteases such as arisulfatase A have been identified, whose function may be associated with metabolic control sulfatides, which is involved in controlling the virus.
