Development and optimization of an efficient RNA isolation protocol from bovine () spermatozoa.

Achieving the optimum extraction of RNA from spermatozoal cells is crucial for carrying out effective high-throughput analysis regarding its role in fertility and other reproduction processes in . Nevertheless, semen comprises spermatozoa and several other secretions from the male reproductive system, which as well consist of diverse somatic cell types. Therefore, the elimination of somatic cells guarantees the purity of the sperm RNA.

miR-192, miR-194, miR-215, miR-200c and miR-141 are downregulated and their common target ACVR2B is strongly expressed in renal childhood neoplasms.

Micro RNAs (miRNAs) play an important role during renal development and show a tissue-specific enrichment in the kidney. Nephroblastomas, embryonal renal neoplasms of childhood, are considered to develop from nephrogenic rests (NRs) and resemble morphologically and genetically developing kidney. We therefore investigated the role of kidney-enriched miRNAs in the pathogenesis of nephroblastomas.
