Identification of microRNAs in corpus luteum of pregnancy in buffalo (Bubalus bubalis) by deep sequencing
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.
