Furthermore, the P171F substitution identified in a strong OsALS1 allele was quickly introduced into the commercial rice cultivar Nangeng 46 through precise base editing with the corresponding base editor and sgRNA. Collectively, these data indicate great potential of BEMGE in creating important genetic variants of target genes for crop improvement. Bovine mammary fibrosis represents a considerable health problem of cows, primarily indicated by lactation failure. Staphylococcus aureus (S. aureus) can cause mammary damage, this multifactorial disease necessitates to identify how and to what extent molecular pathogen defense mechanisms prevent bacterial infections in bovine mammary gland. In this study, we have aimed to determine the transcriptional responses in bovine mammary fibroblasts (BMFBs) induced by S. aureus using bioinformatics analysis to determine whether mRNA expression profile changes between BMFBs activation and quiescence. Established primary BMFBs obtained from healthy Holstein bovine were induced 106 CFU/mL heat-inactivated S. aureus and total RNA was isolated 6 h after treatment. The 574 DEGs were involved in gene ontology (GO) that were immune response, apoptotic process, extracellular region, receptor binding, endopeptidase activity and protein kinase activity et al. The Kyoto Encyclopedia of Genes and Genomes (KEGG) analyses, distinctciated genes in BMFBs. This may lead to development of novel therapeutic targets to control bovine mammary fibrosis induced by S. aureus. Renal and extrarenal production of the active form of vitamin D, 1,25-dihydroxyvitamin D (1,25(OH)2D), is catalyzed by CYP27B1, an enzyme also called 1-α-hydroxylase. The overproduction of 1,25(OH)2D has been described in granulomatous diseases. High circulating concentrations of 1,25(OH)2D can lead to hypercalcemia. The aim of this work was to characterize the transcriptional regulation of CYP27B1 in human mononuclear phagocytes exposed to LPS due to its relevance to understanding the hypercalcemia and ectopic calcifications associated with chronic inflammatory diseases such as tuberculosis and other granulomatous diseases. The human CYP27B1 promoter analysis identified binding sites for published TF, SNPs, novel putative TFBS and conserved sites compared to mice. Then, using microarray data, a meta-analysis was performed to obtain a global view of the gene expression in LPS-challenged dendritic cells, monocytes and macrophages. Finally, two experiments, GSE40885 and time series GSE19765, were analyzed in-depth using differential expression analysis which permitted the identification of TF co-expressed with CYP27B1. This work allowed us to formulate a CYP27B1 transcriptional regulation model for LPS-challenged monocytes/macrophages. The importance of two TF families, NFKB and CEBPB, was confirmed. Data also suggests that PLAGL2 and STAT4 which are novel TF could participate in the CYP27B1 transcriptional regulation in cells exposed to LPS. These TF, in turn, would be interacting with regions that present polymorphisms in the general population which might explain the pathological phenotypes associated with altered vitamin D metabolism. Evidence indicates that higher serum 25-hydroxy vitamin D levels may be associated with decreased prevalence of urgency urinary incontinence (UI), but the impact of vitamin D consumption on development of urgency and mixed UI is unclear. The objective was to assess whether greater vitamin D intake was associated with decreased risk of incident urgency and mixed UI over 10 years using 2 large prospective cohorts of middle-aged and older women. We analyzed 38,101 women from the Nurses' Health Study I (NHS I) and 35,190 women from NHS II who were free of UI at baseline. We followed incident UI, defined as new UI occurring at least monthly, separately by subtype (urgency, mixed, stress UI), from 2002-2012. We categorized vitamin D intake from supplements and diet. RCM-1 price We estimated relative risk for developing UI according to vitamin D intake using Cox-proportional hazard models with adjustment for covariates. Median vitamin D intake was 580IU in the older women in NHS I (age range 56-71 at baseline) and 487IU in middle-aged women in NHS II (age range 40-57). Among women taking ≥1000IU of vitamin D, median intake in the older women was 1252IU and 1202IU in the middle-aged women. Among the older women, we found no relation of vitamin D intake to risk of developing UI, across all UI subtypes. In multivariable-adjusted analysis for middle-aged women, the relative risk of developing mixed UI among women taking >1000IU was 0.79 (0.63, 0.99) and for urgency UI was 0.88 (0.71, 1.07), versus less then 200IU. Risks of developing stress UI were not related to vitamin D intake categories. Overall, we did not find a relationship between vitamin D intake and UI incidence in middle-aged and older women; however, the reported intake was moderate. Prs (phosphoribosyl pyrophosphate synthase) is a broadly conserved protein that synthesises 5-phosphoribosyl 1-pyrophospate (PRPP); a substrate for biosynthesis of at least 10 enzymatic pathways including biosynthesis of DNA building blocks - purines and pyrimidines. In Escherichia coli, it is a protein of homo-hexameric quaternary structure, which can be challenging to work with, due to frequent aggregation and activity loss. Several studies showed brief purification protocols for various bacterial PRPP synthases, in most cases involving ammonium sulfate precipitation. Here, we provide a protocol for expression of E. coli Prs protein in Rosetta (DE3) and BL21 (DE3) pLysE strains and a detailed method for His-Prs and untagged Prs purification on nickel affinity chromatography columns. This protocol allows purification of proteins with high yield, purity and activity. We report here N-terminally His-tagged protein fusions, stable and active, providing that the temperature around 20 °C is maintained at all stages, including centrifugation. Moreover, we successfully applied this method to purify two enzyme variants with K194A and G9S alterations. The K194A mutation in conserved lysine residue results in protein variant unable to synthetize PRPP, while the G9S alteration originates from prs-2 allele variant which was previously related to thermo-sensitive growth. His-PrsG9S protein purified here, exhibited comparable activity as previously observed in-vivo suggesting the proteins purified with our protocol resemble their physiological state. The protocol for Prs purification showed here indicates guidance to improve stability and quality of the protein and to ensure more reliable results in further assays in-vitro.
