Plant lipid transfer proteins (LTPs), belonging to pathogenesis-related protein 14 family, participate in plant immune response to biotic stress. LTP1 from was previously shown to be able to suppress infection by cowpea mosaic virus and soybean mosaic virus. However, whether cowpea LTP1 participates in the plant resistance to other plant pathogens remains unclear.

Heme is biosynthesized in legume root nodules to meet the demand for leghemoglobins (Lbs) and other heme-binding proteins. However, the main source of nodule heme remains unknown. Both the plant host and rhizobia possess a complete heme biosynthetic pathway, differing slightly in the production of 5-aminolevulinic acid (ALA), a key regulatory step catalyzed by glutamyl-tRNA reductase (GluTR) in the plant and by HemA in the rhizobia.

Long noncoding RNAs (lncRNAs) cover a large class of transcribed RNA molecules that are more than 200 nucleotides in length. An increasing number of studies have shown that lncRNAs control gene expression through different mechanisms and play important roles in a range of biological processes including growth, cell differentiation, proliferation, apoptosis, and invasion. TUG1 was originally discovered in a genomic screen of taurine-treated mouse retinal cells.

Introduction: A US Food and Drug Administration-approved new bromodomain (BRD) and extraterminal (BET) bromine domain antagonist called apabetalone, which targets BRD4, has been shown to increase prebeta-1 high-density lipoprotein (HDL) particles, enhance apolipoprotein A-I in both humans and animals, and restore angiogenesis in experimental diabetes. Its action is not however fully known mechanistically. The objective of our research was to investigate the impact of apabetalone on renal damage linked to diabetic kidney disease (DKD).

Pure red cell aplasia (PRCA) is a rare complication of erythropoietin (EPO) therapy, characterized by a severe deficiency in red blood cell production. There is no guideline on the treatment for PRCA because there have been too few cases to perform prospective cohort studies. The main treatments for PRCA include immediate cessation of EPO, restrictive transfusion, and immunosuppressive therapies.

Background: Age-related kidney impairment, characterized by tubular epithelial cell senescence and renal fibrosis, poses a significant global public health threat. Although N6-methyladenosine (m6A) methylation is implicated in various pathological processes, its regulatory mechanism in kidney aging remains unclear.

Methods: An m6A-mRNA epitranscriptomic microarray was performed to identify genes with abnormal m6A modifications in aged human kidney tissues.

Background: The mutualistic beneficial relationship between legume plants and rhizobia enables the growth of plants in nitrogen-limiting conditions. Rhizobia infect legumes through root hairs and trigger nodule organogenesis in the cortex. The plant hormone cytokinin plays a pivotal role in regulating both rhizobial infection and the initiation of nodule development.

Chlamydomonas reinhardtii, a model green alga for expressing foreign proteins, faces challenges in multigene expression and enhancing protein expression level in the chloroplast. To address these challenges, we compared heterologous promoters, terminators and intercistronic expression elements (IEEs). We transformed Chlamydomonas chloroplast with a biolistic approach to introduce vectors containing the NanoLuc expression unit regulated by Chlamydomonas or tobacco promoters and terminators.

Key Points: Patients with IgA nephropathy and significant proteinuria are at high risk of progressive kidney function loss and kidney failure. We report the results of a clinical trial assessing the selective endothelin receptor antagonist SC0062 for the treatment of IgA nephropathy. SC0062 led to clinically meaningful improvements in proteinuria and did not increase risk of peripheral edema at higher doses.

Many virus genomes encode proteases that facilitate infection. The molecular mechanism of plant recognition of viral proteases is largely unexplored. Using the system of and cowpea mosaic virus (CPMV), we identified a cowpea lipid transfer protein (LTP1) which interacts with CPMV-encoded 24KPro, a cysteine protease, but not with the enzymatically inactive mutant 24KPro(C166A).

Depression is one of the most common psychiatric conditions worldwide, with an annual escalation in prevalence. The serotonin (5-Hydroxytryptamine [5-HT]) metabolism through the gut-brain axis has been revealed to be related to the development of depression. Our previous study demonstrated that Lactococcus lactis WHH2078 alleviated depression in mice by shaping the gut microbiome composition and 5-HT metabolism.

Many inflammatory disorders, including diabetic kidney disease (DKD), are associated with pyroptosis, a type of inflammation-regulated cell death. The purpose of this work was to ascertain the effects of apabetalone, which targets BRD4, a specific inhibitor of the bromodomain (BRD) and extra-terminal (BET) proteins that target bromodomain 2, on kidney injury in DKD. This study utilized pharmacological and genetic approaches to investigate the effects of apabetalone on pyroptosis in db/db mice and human tubular epithelial cells (HK-2).

Article Synopsis
  • Diabetic Kidney Disease (DKD) is linked to disruptions in circadian rhythms, and melatonin may help protect the kidneys, though its exact mechanism is still not fully understood.
  • The study used gene analysis, mouse models, and various experimental techniques to explore the role of melatonin in DKD and its interaction with clock genes.
  • Results indicate that melatonin significantly improves kidney conditions in diabetic mice by regulating clock genes and decreasing inflammation through the TLR2/MyD88/NF-κB signaling pathway, highlighting DEC1's potential as a key factor in kidney-related inflammation.

Aims: Several studies have reported dietary microorganisms' beneficial effects on human health. We aimed to detect the potential association between dietary live microbe intake and diabetic kidney disease (DKD) in patients with type 2 diabetes mellitus (T2DM) through a cross-sectional analysis of the National Health and Nutrition Examination Survey from 1999 to 2018.

Methods: According to the Sanders classification system of dietary live microbes, the study participants were divided into three groups: low, medium, and high live microbe groups.

Metabolic syndrome (MS) has emerged as one of the major global health concerns, accompanied by a series of related complications, such as obesity and type-2 diabetes. The gut-liver axis (GLA) is a bidirectional communication between the gut and the liver. The GLA alterations have been revealed to be closely associated with the development of MS.

Mitochondrial dysfunction is implied as a crucial factor in age-related chronic kidney disease. It is confirmed that Gli-like transcription factor 1 (GLIS1) is involved in age-related renal fibrosis, however, the correlation between mitochondrial disturbances and GLIS1-driven kidney aging are not clearly clarified. Thus, we investigated the regulatory mechanism of GLIS1 in the homeostasis of mitochondrial quality control both in vivo and in vitro.

Article Synopsis
  • Growing evidence suggests that diets high in antioxidants may help protect against chronic kidney disease (CKD), but the specific link between the Composite Dietary Antioxidant Index (CDAI) and CKD has not been well explored.
  • A study using data from the National Health and Nutrition Examination Survey (NHANES) 2011-2018 conducted a multivariate analysis to investigate this relationship, involving 6,874 participants that represent a diverse population in the U.S.
  • The findings indicated that higher CDAI scores were associated with a lower prevalence of CKD, particularly among older adults and those with diabetes, highlighting the need for more extensive future research on this topic.
