Rabbit Anti-CASP3 Polyclonal antibody

We aimed to explore the mechanism of pramipexole (PPX) actions in the treatment of Parkinson's disease (PD). Genes related to PD and PPX were screened through bioinformatics retrieval. The PD model was constructed by applying 1-methyl-4-phenylpyridinium (MMP+). The RNA expression levels of circSNCA, SNCA, apoptosisrelated genes (BCL2, CASP3, BAX, PTEN and P53) and miR-7 were detected by qRT-PCR. Protein expression was determined by western blot. The interactions between circSNCA-miR-7-SNCA were verified by dual luciferase assay and immunofluorescence localization. Cell viability was determined by MTT assay. SNCA and circSNCA expression levels in PD were downregulated after PPX treatment, consistent with the levels of pro-apoptotic genes. CircSNCA increased SNCA expression by downregulating miR-7 in PD as a competitive endogenous RNA (ceRNA). Lower circSNCA expression was associated with the reduced expression of pro-apoptotic (CASP3, BAX, PTEN and P53) proteins. CircSNCA downregulation could decrease apoptosis and induce autophagy in PD. In conclusion, the downregulation of circSNCA by PPX treatment reduced cell apoptosis and promoted cell autophagy in PD via a mechanism that served as a miR-7 sponge to upregulate SNCA.

This study was aimed to identify miRNAs of corpus luteum (CL) in buffaloes during pregnancy. For this study, CL (n=2) were collected from gravid uteri of buffalo and RNA was isolated. Following this, the purity and integrity of RNA was checked and used for deep sequencing using Illumina Hiseq 2500 platform. The reads' quality was checked prior to in silico analyses viz. identification of conserved, novel and target of miRNAs. In this study, out of identified miRNAs (3018), 3013 were known and 5 were novel miRNAs on alignment with reference genomes. In addition, prediction of putative target genes for identified abundant miRNAs revealed several genes viz. HOX, KLF4, NCOR2, CDKN2Z, MAPK7, COX2, PPARA, PTEN, ASS3A, ELK1, CASP3, BCL211, MCL1, CCND2, Cyclin A2 and CDC25A during early pregnancy in buffalo. These predicted target genes have been associated with various cellular house-keeping processes including apoptosis. In conclusion, this study reports the identification of conserved and novel microRNAs (miRNAs) in CL during pregnancy in buffalo by deep sequencing.
