Previous studies have reported the miR-513b is located on the X chromosome and is preferentially expressed in testis. However, the underlying mechanisms of miR-513b involved in spermatogenesis remains unknown. In this study, we found that hsa-miR-513b-5p was highly expressed in the testes of infertile males with maturation arrest compared with normal controls. Overexpression of hsa-miR-513b-5p suppressed...
Beta-defensins (β-defensins) are small cationic amphiphilic peptides that are widely distributed in plants, insects, and vertebrates, and are important for their antimicrobial properties. In this study, the β-defensin (Onβ-defensin) gene of the Nile tilapia (Oreochromis niloticus) was cloned from spleen tissue. Onβ-defensin has a genomic DNA sequence of 674bp and produces a cDNA of 454bp. Sequence...
Past efforts to improve plant tolerance to osmotic stress have had limited success owing to the genetic complexity of stress responses. The first step towards cataloging and categorizing genetically complex abotic stress responses is the rapid discovery of genes by the large-scale partial sequencing of randomly selected cDNA clones or expressed sequence tags (ESTs). Suaeda salsa, which can survive...
