Project description:Green plants are more robust to hydrogen peroxide (H2O2) stress and contain high endogeneous H2O2 levels which is generated during photorespiration and photosynthesis. Therefore, exgeneous H2O2 application mostly impose oxidative stress. To reduce endogenous H2O2 background, we adopted a strategy which is to grow Arabidopsis seedlings in the dark to eliminate light-induced H2O2 production, thus to reduce the endogenous H2O2 level. Exogenous H2O2 was then applied to induce transcriptome changes. Global gene expression is studied and compared between samples collected under 7d dark, 7d H2O2 treatment under dark and 7d light conditions.

Project description:This study investigates the role of peroxiredoxin 2 (PRDX2) in mediating oxidative adaptations in human skeletal muscle myotubes subjected to mechanical contraction and hydrogen peroxide (H2O2) exposure. additionally, the effect of an electrical stimulation protocol was assessed pre and post PRDX2 KD along with two concentrations of H2O2.

Project description:<p>Background The gut microbiota plays a significant role in modulating the growth and function of host muscle, and microbiota transplantation experiments provide compelling evidence of its capacity to improve muscle quality. Feeding faba beans improves the muscle quality of Yellow River carp. However, the changes in gut microbiota, along with the specific microorganisms, metabolic pathways, and regulatory mechanisms linked to the enhancement of muscle quality following faba bean consumption remain to be elucidated.</p><p>Results After a 6-week feeding trial with faba beans, growth performance decreased, but muscle texture improved (P < 0.05). Gut microbiota structure also changed, with increased relative abundances of Aeromonas, ZOR0006, Cetobacterium, and Atopobium. Following 8 weeks of whole-intestinal microbiota transplantation (WIMT) from faba bean-fed donors to basal diet-fed recipients of Yellow River carp, growth performance remained unchanged (P > 0.05), while muscle texture improved (P < 0.05). This improvement was mainly due to increased small-diameter muscle fibers, higher collagen levels, and reduced muscle fat content (P < 0.05), which partially replicated the muscle texture of donor fish. Moreover, WIMT promotes intestinal structure and barrier integrity, with significant changes in gut microbiota structure and metabolic profile. WIMT improved the muscle quality of Yellow River carp by regulating mitochondrial autophagy and adipocytokine signaling pathways through the gut-muscle axis. Cetobacterium somerae (C. somerae) and its metabolites, such as acetic acid, played a crucial role in this process. Further feeding experiments demonstrated that C. somerae and acetic acid reduced the crude fat content of muscle while increasing the crude protein and collagen (P < 0.05). C. somerae also mitigated muscle protein degradation under inflammatory and enhanced collagen (P < 0.05), thereby improving muscle texture.</p><p>Conclusion This study establishes that gut microbiota enhance muscle quality in Yellow River carp through WIMT, identifies C. somerae and its metabolite acetic acid as key contributors. The findings provide novel evidence for fish gut-muscle axis research and offer new scientific basis for improving Yellow River carp muscle quality.</p>

Project description:This study was performed with the goal of understanding the roles of Leishmania donovani SET7 and SET29 proteins in gene regulation. Using homologous recombination to knock out set7 and set29 genes, set7 and set29 mutant parasites were created. This was folllowed by transcriptome analyses of wild type parasites, set7 mutant parasites and set29 mutant parasites, that were carried out using RNA-seq. In the first experimental set, transcriptomes of wild type parasites cultured under normal conditions as well as under hydrogen peroxide (H2O2) -induced oxidizing conditions were analysed, along with transcriptomes of set7 mutant parasites that were similarly grown under normal growth conditions as well as under H2O2-induced oxidizing conditions. Using the data obtained, the transcriptome of wild type parasites exposed to H2O2 has been compared with the transcriptome of wild type parasites grown under normal conditions. The transcriptome of set7 mutant parasites grown under H2O2-induced oxidizing conditions versus normal conditions have been similarly compared. In addition, the transcriptome of set7 mutant parasites grown under normal conditions has been compared to that of similarly grown wild type parasites. In the second experimental set, transcriptomes of wild type parasites cultured under normal growth conditions, set29 mutant parasites grown under normal conditions, as well as set29 mutant parasites grown under H2O2-induced oxidizing conditions, were analysed. Using the data obtained, the transcriptome of set29 mutant parasites grown under normal conditions has been compared to that of similarly grown wild type parasites. The transcriptome of set29 mutant parasites grown under H2O2-induced oxidizing conditions versus normal conditions have been similarly compared. Our data reveals, that knock out of set7 modulates transcription of specific clusters of genes on particular chromosomes, with almost 10 % of the total genes being regulated. On the other hand, depletion of SET29 modulates transcription of a very small set of genes distributed primarily in two clusters. This datasheet is for second experimental set.

Global gene expression is studied and compared between samples collected under 7d dark, 7d H2O2 treatment under dark and 7d light conditions. We cultured seedlings in the dark to reduce endogenous H2O2. Three conditions were used for transcriptome profiling: dark grown (dark); dark grown with exogenous H2O2 treatment (H2O2); and light grown (light). Three types of conditions were used for Arabidopsis seedling culture: dark, dark with 5 mM H2O2 treatment and light. Each condition was performed with two biological replicates. The seedlings were harvested at 7 days old.
