Discovery of Ureido-Containing Alteropeptilides and Intramolecular Cyclized Alteramides in S16 by Promoter Engineering of Cryptic Biosynthetic Gene Clusters.

are abundant in the oceans and possess great potential in the synthesis of bioactive natural products. Although many secondary metabolite biosynthetic gene clusters have been identified from genomes, most of their products have not been characterized. In this study, endogenous constitutive promoters with high transcriptional activity were obtained from S16 through RNA-seq and a fluorescence assay of luciferase gene expression.

miR-181d targets BCL2 to regulate HCT-8 cell apoptosis and parasite burden in response to Cryptosporidium parvum infection via the intrinsic apoptosis pathway.

Cryptosporidium parvum is an important zoonotic pathogen that is studied worldwide. MicroRNAs (miRNAs) act as post-transcriptional regulators and may play a key role in modulating host epithelial responses following Cryptosporidium infection. Our previous study has shown that C.

Functional characterization of CpADF, an actin depolymerizing factor protein in Cryptosporidium parvum.

Cryptosporidium is a highly pathogenic water and food-borne zoonotic parasitic protozoan that causes severe diarrhea in humans and animals. Apicomplexan parasites invade host cells via a unique motility process called gliding, which relies on the parasite's microfilaments. Actin depolymerizing factor (ADF) is a fibrous-actin (F-actin) and globular actin (G-actin) binding protein essential for regulating the turnover of microfilaments.

Serum Isthmin-1 is negatively correlated with HDL-C in type 2 diabetes mellitus.

Background: Isthmin-1 (Ism-1) is a newly identified insulin-like adipokine that increases glucose uptake by adipocytes and inhibits hepatic lipid synthesis. Recent studies have shown that Ism-1 can improve the metabolic disorders associated with type 2 diabetes mellitus (T2DM) and improve lipid metabolism. The classic function of high-density lipoprotein cholesterol (HDL-C) is to transport cholesterol from extra-hepatic tissues to the liver for metabolism.

Serum isthmin-1 levels are positively and independently correlated with albuminuria in patients with type 2 diabetes mellitus.

Introduction: Isthmin-1 (Ism-1), as a novel adipokine, plays a role in glucose homeostasis and lipid metabolism. However, the relationship between Ism-1 and type 2 diabetes mellitus (T2DM) remains unclear. This study aims to investigate the association of serum Ism-1 levels with albuminuria and insulin resistance in patients with T2DM and preserved renal function.

Cryptosporidium parvum downregulates miR-181d in HCT-8 cells via the p50-dependent TLRs/NF-κB pathway.

Cryptosporidium spp. can cause diarrhea and even death in humans and animals. Host microRNAs (miRNAs) play an important role in the post-transcriptional regulation of the innate immune response to Cryptosporidium infection.

Alterations of DNA methylation were associated with the rapid growth of cortisol-producing adrenocortical adenoma during pregnancy.

Background: Cortisol-producing adrenocortical adenoma (CPA) during pregnancy rarely occurs in clinic. Growing evidence suggests that DNA methylation plays a key role in adrenocortical adenomas. The present study aims to examine the genome-wide DNA methylation profiles and identify the differences in DNA methylation signatures of non-pregnant and pregnant patients with CPA.

β-Cell function is associated with osteosarcopenia in middle-aged and older nonobese patients with type 2 diabetes: A cross-sectional study.

Type 2 diabetes mellitus (T2DM) is a strong risk tfactor for osteosarcopenia. The relationship between musculoskeletal index and β-cell function remains controversial. We aimed to describe the clinical characteristics of osteosarcopenia and to explore the association between osteosarcopenia and β-cell function, as well as insulin resistance in patients with T2DM.

Novel PIK3R1 mutation of SHORT syndrome: A case report with a 6-month follow up.

SHORT syndrome (short stature, hyperextensibility, ocular depression [deeply set eyes], Rieger anomaly and teething delay) is very rare, with a few cases reported in the literature. We report a case of SHORT syndrome with a novel PIK3R1 mutation (c.2008delT) and complicated with severe insulin resistance.

Quantitative Proteomic Analysis Provides Insights into Rice Defense Mechanisms against .

Blast disease is one of the major rice diseases, and causes nearly 30% annual yield loss worldwide. Resistance genes that have been cloned, however, are effective only against specific strains. In cultivation practice, broad-spectrum resistance to various strains is highly valuable, and requires researchers to investigate the basal defense responses that are effective for diverse types of pathogens.

Osa-miR164a targets OsNAC60 and negatively regulates rice immunity against the blast fungus Magnaporthe oryzae.

Exploring the regulatory mechanism played by endogenous rice miRNAs in defense responses against the blast disease is of great significance in both resistant variety breeding and disease control management. We identified rice defense-related miRNAs by comparing rice miRNA expression patterns before and after Magnaporthe oryzae strain Guy11 infection. We discovered that osa-miR164a expression reduced upon Guy11 infection at both early and late stages, which was perfectly associated with the induced expression of its target gene, OsNAC60.
