Eight-cluster structure of chloroplast genomes differs from similar one observed for bacteria [PDF]

arXiv, 2018
Previously, a seven-cluster pattern claiming to be a universal one in bacterial genomes has been reported. Keeping in mind the most popular theory of chloroplast origin, we checked whether a similar pattern is observed in chloroplast genomes. Surprisingly, eight cluster structure has been found, for chloroplasts.

Permanent draft genome sequence of Frankia sp. NRRL B-16219 reveals the presence of canonical nod genes, which are highly homologous to those detected in Candidatus Frankia Dg1 genome [PDF]

, 2017
Frankia sp. NRRL B-16219 was directly isolated from a soil sample obtained from the rhizosphere of Ceanothus jepsonii growing in the USA. Its host plant range includes members of Elaeagnaceae species.

Correlation Between Fecal Microbiota and Corticosteroid Responsiveness in Primary Immune Thrombocytopenia: an Exploratory Study

Advanced Science, EarlyView.
This study uses gut microbiome data to predict corticosteroid response in patients with immune thrombocytopenia (ITP). Fecal samples from 212 patients with ITP are sequenced. Six machine‐learning algorithms are used to train predictive models. The support vector machine‐based model integrated clinical data and selected microbial species, diversities ...

Conjugated Lithocholic Acid Activates Hepatic TGR5 to Promote Lipotoxicity and MASLD‐MASH Transition by Disrupting Carnitine Biosynthesis

Advanced Science, EarlyView.
Takeda G protein‐coupled receptor 5 (TGR5) serves as a central regulator in the metabolic dysfunction‐associated steatotic liver disease (MASLD)/metabolic dysfunction‐associated steatohepatitis (MASH) transition via conjugated lithocholic acid (LCA). Mechanistically, TGR5 orchestrates lipotoxicity‐induced cell death through its interaction with CD36 ...

Revolutionising Bacterial Genomics: Graph-Based Strategies for Improved Variant Identification [PDF]

arXiv
A significant advancement in bioinformatics is using genome graph techniques to improve variation discovery across organisms. Traditional approaches, such as bwa mem, rely on linear reference genomes for genomic analyses but may introduce biases when applied to highly diverse bacterial genomes of the same species.

Gut Microbiota‐Butyrate‐PPARγ Axis Modulates Adipose Regulatory T Cell Population

Advanced Science, EarlyView.
This study identifies the indispensable role of gut microbiota in the maintenance of ST2+ adipose Treg cell population, and defines gut microbiota‐derived butyrate as an endogenous PPARγ agonist, modulating adipose Treg cell populations via promoting PPARγ activation. Butyrate or fiber supplementation restores the VAT ST2+ Treg population in obese mice

Whole-Genome Phenotype Prediction with Machine Learning: Open Problems in Bacterial Genomics [PDF]

arXiv
How can we identify causal genetic mechanisms that govern bacterial traits? Initial efforts entrusting machine learning models to handle the task of predicting phenotype from genotype return high accuracy scores. However, attempts to extract any meaning from the predictive models are found to be corrupted by falsely identified "causal" features ...

Mas Signaling Potentiates Neutrophil Extracellular Traps Formation Induced by Endothelial Cells Derived S1P in Mice with Acute Liver Failure

Advanced Science, EarlyView.
In mice challenged with lipopolysaccharide/D‐galactosamine (L/G), Mas signaling increased SHP2 in hepatic Col4a1+ endothelial cells, inhibiting farnesoid X receptor (FXR), potentially due to enterogenic deoxycholic acid. This inhibition activates sphingosine‐1‐phosphate‐induced Raf/MEK/ERK signaling in Cldn1+CD177+ neutrophils, causing neutrophil ...

Zonated Copper‐Driven Breast Cancer Progression Countered by a Copper‐Depleting Nanoagent for Immune and Metabolic Reprogramming

Advanced Science, EarlyView.
Spatially resolved multiomics reveals that high‐copper zones are closely associated with tumor metastasis, immune‐desert phenotypes, and oxidative‐phosphorylation (OXPHOS)‐dependent proliferation. A targeted bacterial nanovesicle delivering copper‐depleting agents effectively reduces tumor copper levels, inhibits OXPHOS‐dependent tumor growth, and ...

Gut Microbiota Modulation by Inulin Improves Metabolism and Ovarian Function in Polycystic Ovary Syndrome

Advanced Science, EarlyView.
This work proposes a novel strategy targeting gut microbiota for managing polycystic ovary syndrome (PCOS). Inulin, a gut microbiota modulator, notably boosts the growth of short‐chain fatty acids (SCFAs)‐producers, represented by Bifidobacterium, thereby improving glucolipid metabolism and ovarian function of PCOS through suppressing the inflammatory ...
