Reshaping commensal gut microbiota in early life with amoxicillin presents with lower blood pressure
Contributors: Saroj Chakraborty
... Pediatric hypertension is recognized as an emerging global health concern. While new guidelines are developed for facilitating clinical management, the reasons for the prevalence of hypertension in children remain unknown. Genetics and environmental factors do not fully account for the growing incidence of pediatric hypertension. Because stable bacterial flora in early life are linked with health outcomes later in life, we hypothesized that reshaping of gut microbiota in early developmental stages of life affects blood pressure (BP) of pediatric subjects. To test this hypothesis, we administered amoxicillin, the most commonly prescribed pediatric antibiotic, to alter gut microbiota of young, genetically hypertensive rats (study 1) and dams during gestation and lactation to reshape microbiota of offspring (study 2). Reshaping of microbiota, with reductions in Firmicutes/Bacteriodetes ratio observed in Amoxicillin treated young rats and in dams. Amoxicillin treated rats also had lower blood pressure compared to the untreated rats. In the young rats treated with amoxicillin, the lowering effect on blood pressure persisted even after the antibiotics were discontinued. Similarly, the offspring from the dams treated with amoxicillin also showed lower systolic blood pressure compared to the control rats. Remarkably, in all cases, a decrease in BP was associated with lowering of Veillonellaceae, which are succinate-producing bacteria. Elevated plasma succinate is reported in hypertension. Accordingly, serum succinate was measured and found lower in animals treated with amoxicillin. Our results demonstrate a direct correlation between succinate-producing gut microbiota and early development of hypertension, and indicate that reshaping gut microbiota, especially by depleting succinate-producing microbiota early in life may have long-term benefits for hypertension-prone individuals.

... Raw 16S rRNA sequencing data from luminal contents from sections of the small (SI) and large intestines (LI) of 10 Swiss-Webster female mice (S+) that were infected with 200 S. mansoni cercariae and 10 age- and gender-matched mice that remained uninfected and were included as controls (S-). For each S+ and S- group, five mice were euthanised 28 days after infection (D28 p.i., i.e. before egg laying by sexually mature S. mansoni females had commenced). The remaining mice (n = 5 for each S+ and S-) were euthanised at day 50 p.i. (D50 p.i., corresponding with ongoing egg laying by sexually mature S. mansoni females). The experiment was carried out in duplicate and samples from both experiments (i.e. Exp. 1 & Exp. 2) pooled for further analysis. The data set includes four types of files: 1. Raw joined read files - 1 per sample (demultiplexed): e.g. Exp1_SI_S-_D50_1.fasta 2. Joined, quality filtered file containing reads from all samples and ready for OTU picking. The file was generated using Qiime: seqs.fna 3. Metadata file containing the relevant contextual information for each sample: Schisto_microbiome_Metadata.csv 4. OTU table created using Qiime including all of the taxonomic information: otu_table_mc2_w_tax_no_pynast_failures.biom

Essential gene profiles for human pluripotent stem cells identify uncharacterized genes and substrate dependencies. Mair et al.

... Human pluripotent stem cells (hPSCs) provide an invaluable tool for modeling diseases and hold promise for regenerative medicine. For understanding pluripotency and lineage differentiation mechanisms, a critical first step involves systematically cataloging genes that are indispensable for hPSC maintenance and proliferation. To map genetic determinants of hPSC fitness, we performed genome-scale loss-of-function screens in an inducible Cas9 H1 hPSC line cultured on feeder cells and feeder-free to identify essential genes. Among these, we found FOXH1 and VENTX, genes that encode transcription factors previously implicated in stem cell biology, as well as an uncharacterized gene, C22orf43/DRICH1. hPSCs essential genes are substantially different from other cell lines, and gene essentiality in hPSCs is highly context-dependent with respect to different growth substrates. Our CRISPR screens establish parameters for genome-wide screens in hPSCs, which will facilitate the characterization of unappreciated regulators of hPSC biology to understand the genetic wiring of hPSC fitness and pluripotency.

... Whole exome and transcriptome sequencing data for two patients with high-grade serous ovarian cancer. Data was used to identify non-synonymous somatic mutations which were predicted to give rise to neoantigens. Predicted neoantigens were filtered using peptide-MHC binding prediction algorithms. Neoantigens with a high predicted binding affinity were synthesised and screening for immunogenicity using autologous expanded TIL.
