The purpose of this study is to characterize a meta-signature of differentially expressed mRNA in chronic kidney disease (CKD) to predict putative microRNA (miRNA) in CKD–mineral bone disorder (CKD–MBD) and confirm the changes in these genes and miRNA expression under uremic conditions by using a cell culture system. PubMed searches using MeSH terms and keywords related to CKD, uremia, and mRNA arrays were conducted. Through a computational analysis, a meta-signature that characterizes the significant intersection of differentially expressed mRNA and expected miRNAs associated with CKD–MBD was determined. Additionally, changes in gene and miRNA expressions under uremic conditions were confirmed with human Saos-2 osteoblast-like cells. A statistically significant mRNA meta-signature of upregulated and downregulated mRNA levels was identified. Furthermore, miRNA expression profiles were inferred, and computational analyses were performed with the imputed microRNA regulation based on weighted ranked expression and putative microRNA targets (IMRE) method to identify miRNAs associated with CKD occurrence. TLR4 and miR-146b levels were significantly associated with CKD–MBD. TLR4 levels were significantly downregulated, whereas pri-miR-146b and miR-146b were upregulated in the presence of uremic toxins in human Saos-2 osteoblast-like cells. Differentially expressed miRNAs associated with CKD-MBD were identified through a computational analysis, and changes in gene and miRNA expressions were confirmed with an in vitro cell culture system.

Naturally-occurring environmental microorganisms may provide ‘green’ and effective biocontrol tools for disease management in agricultural crops. Due to the constant threat of resistant pathogens there is a pressing and continual need to search for new biocontrol tools. This study investigated the production of new analogs of WAP-8294A compounds by the biocontrol agent Lysobacter enzymogenes OH11 through biosynthetic engineering. WAP-8294As are a family of natural cyclic lipodepsipeptides with potent activity against Gram-positive bacteria. A series of genetic manipulations was therefore conducted on the accessory genes in the WAP biosynthetic gene cluster. The resulting strains containing a single-point mutation in ORF4, which was predicted to encode a 2-ketoglutarate dependent dioxygenase, produced deoxy-WAP-8294As. This result provides evidence for the function of ORF4 in catalyzing β-hydroxylation of the D-asparagine residue in WAP-8294As. In addition, six new analogs of WAP-8294As were identified by UHPLC-HR-MS/MS. This is the first attempt to produce new WAP-8294As in Lysobacter and shows that the spectrum of the biocontrol compounds may be expanded through the manipulation of biosynthetic genes.

The activity of free radicals in follicular fluid was related to ovarian responsiveness, in vitro fertilization (IVF), and embryo transfer success rate. However, studies analyzing the relationship between the free radical scavenging capacity and embryo quality of infertile women with polycystic ovarian syndrome (PCOS) were lacking. The aim of this study was to evaluate the relationship between the free radical scavenging window of women with PCOS and their embryo quality. The free radical scavenging capacity of follicular fluid from women with PCOS was determined by a,a-diphenyl-b-picrylhydrazyl (DPPH), 2,2-azinobis (3-ethylbenzthiazoline-6-sulphonic acid) assay, superoxide radical, and reactive oxygen species (ROS) assay. In the DPPH and ROS assays, the follicular fluid from grades I and II embryos was significantly higher than the follicular fluid from grades III and IV embryos. The lower control limit of DPPH radical scavenging capacity and upper control limit of ROS level were 13.2% and 109.0 cps, respectively. The calculated lower control limit and upper control limit were further confirmed in the follicular fluid of embryos of all grades. These cut-off values of free radical scavenging activity of follicular fluid could assist embryologists in choosing the development of embryos in PCOS patients undergoing IVF.
