Project description:Comparing the transcriptome of wildtype and kdm5 mutant flies in normal conditions revealed a total of 4787 genes that were significantly downregulated and thus require KDM5 for their activation, and 3269 upregulated genes that are normally repressed by KDM5 (p<0.05, FDR <0.05). Because kdm5 mutants are sensitive to the oxidizer paraquat, we also carried out RNA-seq from wildtype and kdm5 mutant adults in oxidative stress conditions. Paraquat treatment of wildtype flies lead to the upregulation of 2481, and downregulation of 3103 genes adult mRNA profiles of 1-3-days old wild type (WT) and kdm5 mutant under normal condition and oxitative stress were generated by deep sequencing, using Illumina HisSeq 2000.

Project description:To determine which genes affected by loss of KDM5 in adults were direct targets, we carried out KDM5 ChIP-seq analyses. To valide this data, we utilized a previously generated fly strain in which the sole source of KDM5 is from a transgene expressing an HA tagged form of KDM5 expressed under the control of its endogenous promoter. Comparing genome-wide gene expression and KDM5 binding analyses in Drosophila adults, we demonstrate the primary function of KDM5 in adults is to activate gene expression KDM5. To investigate the link between KDM5 and H3K4me3, we carried out anti-H3K4me3 ChIP-seq from wildtype adults . Genome-wide, KDM5 and H3K4me3 peaks showed a similar distribution, with both peaking at the transcription start site (TSS) showed a striking overlap with the presence of H3K4me3.

Project description:Profiled the effect of oxidative stress on gene expression in the heads of adult Drosophila. The flies were fed sucrose with 15mM paraquat (experimental condition) or regular sucrose (control condition) for 30 hours, before harvesting at adult d3. Keywords = oxidative stress Keywords = paraquat Keywords: dose response

Project description:Alzheimer's disease (AD) is the most common form of dementia in the elderly, affecting cognitive, intellectual, and motor functions. Different hypotheses explain AD’s mechanism, such as the amyloidogenic hypothesis. Moreover, this disease is multifactorial, and several studies have shown that gut dysbiosis and oxidative stress influence its pathogenesis. Knowing that kefir is a probiotic used in therapies to restore dysbiosis and that the bioactive peptides present in it have antioxidant properties, we explored its biotechnological potential as a source of molecules capable of modulating the amyloidogenic pathway and reducing oxidative stress, contributing to the treatment of AD. For that, we used Drosophila melanogaster model for AD (AD-like flies). Identification of bioactive peptides in the kefir sample was made by proteomic and peptidomic analyses, followed by in vitro evaluation of antioxidant and acetylcholinesterase inhibition potential. Flies were treated and their motor performance, brain morphology, and oxidative stress evaluated. Finally, we performed molecular docking between the peptides found and the main pathology-related proteins in the flies. The results showed that the fraction with the higher peptide concentration was positive for the parameters evaluated. In conclusion, these results revealed these kefir peptide-rich fractions have therapeutic potential for AD.
