- (pea aphid) is a major pest of Fabaceae (legume) crops, causing direct feeding damage and transmitting plant diseases. Conventional control relies on broad-spectrum insecticides and natural enemies, both of which can harm non-target organisms and ecosystems. RNA interference (RNAi) offers a promising, species-specific alternative by silencing essential genes double-stranded RNA (dsRNA). This study targeted two heat shock protein Genes-Heat Shock 70 kDa Protein 1-Like () and Heat Shock Protein 90 kDa beta (Grp94) Member 1 ()-key players in protein folding, quality control, and stress response within the Unfolded Protein Response () pathway. These chaperones stabilize proteins, assist in folding newly synthesized polypeptides, and target misfolded proteins for degradation. Silencing these genes was hypothesized to cause accumulation of misfolded proteins, triggering Endoplasmic Reticulum (ER) stress, overload, and ultimately apoptosis, leading to aphid mortality. Total RNA was extracted from adult pea aphids, reverse-transcribed to cDNA, and used to synthesize gene-specific dsRNAs for and . These dsRNAs were encapsulated in Branched-Amphiphilic Peptide Capsules (BAPCs) and delivered orally at concentrations of 10 ng/μL and 100 ng/μL artificial diet feeding. Survival was monitored every 6 hours for 48 hours on dsRNA diet, followed by transfer to healthy faba bean leaves. Preliminary studies indicated positive correlations between gene knockdown and elevated mortality. Results demonstrated significantly reduced survival in treated groups compared to controls at both concentrations (Kaplan-Meier survival analysis, log-rank p<0.001), supporting the induction of apoptosis. This approach highlights the potential of -targeted RNAi for eco-friendly, targeted pest control. - Source: PubMed

Davies GriffinBalthazor James - The heat shock protein 70 (Hsp70) family is essential for maintaining protein homeostasis and mediating responses to environmental stresses; however, comprehensive characterizations of this family in the mandarin fish (Siniperca chuatsi) are presently absent. Through comparative genomic analysis, a total of 178 Hsp70 genes were identified across nine vertebrate species (human, mouse, and seven teleost fishes), including 17 unique members within the mandarin fish genome. Phylogenetic and gene structure analyses demonstrated that the mandarin fish Hsp70 family has remained highly conserved throughout teleost evolution, marked by lineage-specific expansions (notably in hspa1, hspa4, hspa8, and hspa12) and selective gene loss (e.g., the absence of hspa2 and hspa6). Specifically, tandem duplication was observed for hspa8.1 and hspa8.2, at the same time, two pairs of syntenic genes (hspa4a/hspa4b and hyou1/hspa8b) were found. Ka/Ks analysis further indicated that this gene family has mainly evolved under purifying selection. Transcriptomic profiling showed that hspa8.1 was constantly expressed across all examined tissues. In addition, under thermal stress and Aeromonas hydrophila infection, Hsp70 genes in mandarin fish exhibited divergent expression patterns: certain members contribute to basal homeostasis (e.g., hspa8.1), whereas others demonstrate specialized responses to heat/cold adaptation (e.g., hspa5) or pathogen infection (e.g., hspa1l). Respectively, these findings together provide a thorough understanding of the composition, evolutionary trajectory, and stress-responsive dynamics of the Hsp70 family, establishing a foundational molecular basis for understanding the environmental adaptation of mandarin fish. - Source: PubMed

Liu YufeiYao XiaoliGao JinhuaIsmaeel HossamChen XiaowuZhao Jinliang - : This study aimed to assess the effects of postbiotic derived from (Szendi2020) on endothelial responses under LPS-induced inflammatory stress. : In human umbilical vein endothelial cells (HUVECs), inflammation was induced with 200 ng/mL LPS. Cell viability, apoptosis, and mitochondrial integrity were assessed using MTT assay, DiIC, and Sytox Green permeability assays. Intracellular ROS levels, heat shock proteins (HSPB1/Hsp27, HSPA1L/Hsp70), adhesion molecules (ICAM-1, VCAM-1), tight junction protein (Occludin), transcription regulators (NF-κB, TNFα), and proinflammatory cytokines (IL-1β, IL-6, IL-8) were quantified using qPCR and ELISA. : LPS exposure significantly induced apoptosis in HUVECs, as reflected by decreased metabolic activity, decreased mitochondrial membrane potential, and increased cell death ( < 0.05). Concurrent postbiotic administration completely abolished LPS-induced cytotoxicity in all assay platforms, demonstrating a potent cytoprotective effect. Postbiotic treatment significantly reduced LPS-induced ROS accumulation ( < 0.05). LPS significantly increased Hsp27 and Hsp70 mRNA expression. However, combined LPS and postbiotic exposure mitigated Hsp27 and Hsp70 mRNA expression compared with LPS treatment alone ( < 0.001, < 0.005). Postbiotic treatment also decreased the upregulation of adhesion molecules induced by LPS. Although this effect decreased after 24 h ( < 0.001). LPS strongly increased NF-κB, IL-1β and TNFα mRNA levels and was suppressed by postbiotics at early time points but not maintained over 24 h. Importantly, postbiotics significantly reduced IL-6, and IL-8 expression at both the mRNA and protein levels, highlighting the attenuation of endothelial inflammatory features ( < 0.05, < 0.005, < 0.001). : Our results are the first to demonstrate that postbiotics derived from (Szendi2020) exert potent cytoprotective and anti-inflammatory effects in LPS-induced endothelial inflammation. By reducing ROS accumulation, preventing apoptosis, stabilizing mitochondrial and barrier integrity, modulating HSP, NF-κB, and cytokine responses. Postbiotics may be promising therapeutic candidates for alleviating endothelial inflammation and the resulting endothelial dysfunction. - Source: PubMed

Using data from the prospective UK Biobank cohort, we evaluated the bidirectional associations by time-varying Cox proportional hazards regression models and assessed shared genetic architecture using genome-wide association study summary statistics. Additionally, we employed collagen-induced arthritis (CIA) and chronic social defeat stress (CSDS) mouse models to investigate the relationship between rheumatoid arthritis (RA) and depression. Over 5,226,841 person-years of follow-up, 23,534 incident MDD cases were identified. The presence of any IMD was associated with higher MDD risk (hazard ratio [HR]: 1.95; 95% CI: 1.89-2.01). Conversely, 59,742 incident cases of IMD were documented. MDD was associated with increased IMD risk (HR: 1.47; 95% CI: 1.40-1.54). We observed significant global genetic correlations between IMDs and MDD (r: 0.11-0.49) and identified 128 pleiotropic genes, including ZKSCAN4, BTN3A2, and HSPA1L. Clinically, RA patients exhibited systemic inflammation and decreased levels of brain-derived neurotrophic factor. In experimental models, CIA mice showed depressive-like behaviors and lesions in brain regions implicated in depression. Moreover, superimposing CSDS on CIA exacerbated depressive-like behavior and pain sensitivity, accelerated the onset and progression of arthritis, and heightened joint inflammation. Collectively, these population, genetic, and experimental findings support a bidirectional association and shared genetic susceptibility between IMDs and MDD, highlighting immune-neurobiological pathways, particularly those involving inflammation and neurotrophin dysregulation, as candidates for mechanistic dissection and therapeutic targets. - Source: PubMed

Despite their adaptive advantages, Butana cattle face the risk of genetic erosion due to low production performance and the absence of structured breeding programs underscoring the urgent need to conserve their unique genetic potential for climate-resilient livestock development. - Source: PubMed
