Evaluation of the gut microbiome and sex hormones in postmenopausal women with newly diagnosed hormone receptor-positive breast cancer versus healthy women: a prospective case-control study

open access: yesJournal of Cancer Research and Clinical Oncology
Purpose The functional composition and diversity of the gut microbiome may affect breast cancer risk by modulation of systemic sex hormones. Gut bacteria with β-glucuronidase enzymatic activity may deconjugate estrogens, leading to increased estrogen ...

Analysis of CcDREB1D promoter region from drought-tolerant and susceptible clones of Coffea canephora by homologous genetic transformation of Coffea arabica [PDF]

open access: yes, 2014
In several plant species, the DREB genes play a key role in responses to abiotic stress. Since the development of molecular markers is one of the major goals for accelerating breeding programs, a study was done to evaluate the sequence variability of the

SIB1‐SEC23A undergo ER to chloroplast relocalization to mediate immunity in Arabidopsis thaliana

open access: yesJournal of Integrative Plant Biology, EarlyView.
SEC23A mediates membrane trafficking between the endoplasmic reticulum (ER) and Golgi apparatus and interacts with the immunity protein SIGMA FACTOR‐BINDING PROTEIN1 in Arabidopsis. Under stress, both proteins relocate from the ER to chloroplasts, suppressing photosynthesis genes and enhancing defense genes.

Mutation in the pssZ Gene Negatively Impacts Exopolysaccharide Synthesis, Surface Properties, and Symbiosis of Rhizobium leguminosarum bv. trifolii with Clover [PDF]

open access: yes, 2018
Rhizobium leguminosarum bv. trifolii is a soil bacterium capable of establishing a nitrogen-fixing symbiosis with clover plants (Trifolium spp.). This bacterium secretes large amounts of acidic exopolysaccharide (EPS), which plays an essential role in ...

Arabidopsis inositol polyphosphate kinase activities regulate COP9 deneddylation functions in phosphate homeostasis

open access: yesJournal of Integrative Plant Biology, EarlyView.
Plant phosphate (Pi) homeostasis relies on coordinated activities of the inositol polyphosphate kinases IPK1 and ITPK1, which balance localized InsP7 biosynthesis to control COP9 signalosome (CSN)‐dependent deneddylation of cullin 1 (CUL1). Perturbation of this equilibrium affects the stability of SPX4, a key negative regulator of phosphate starvation ...

Demonstration of chondroitin sulfates degrading endo-β-glucuronidase activity in rabbit liver [PDF]

open access: yes, 1985
Reduced chondroitin sulfate was incubated with rabbit liver extracts followed by reduction once more with sodium [3H]borohydride, and then passed through a Sephadex G-100 column.

The vesicle trafficking R‐SNARE VAMP714 connects auxin responses, ROS and ion homeostasis in Arabidopsis under salt stress

open access: yesNew Phytologist, EarlyView.
Network of VAMP714‐dependent interactions during salt stress. Summary Plant responses to salt stress include an altered root architecture mediated by ion imbalances, reactive oxygen species (ROS) accumulation, and altered hormonal responses. Auxin is implicated in these processes.

Endometrial Dysbiosis: A Possible Association with Estrobolome Alteration

open access: yesBiomolecules
Background/Objectives: Microbiota modification at the endometrial level can favor gynecological diseases and impair women’s fertility. The overgrowth of pathogen microorganisms is related to the contemporary alteration of estrogen-metabolizing bacteria ...

A broad host range reporter plasmid for the analysis of divergent promoter regions [PDF]

open access: yes, 2008
Although many vectors exist for Escherichia coli and closely related species, there are few broad host range vectors that can be conjugated into a large variety of Gram-negative bacteria.

COCHLEATA controls spatial regulation of cytokinin and auxin during nodule development

open access: yesNew Phytologist, EarlyView.
Nodule development defects in the coch mutant include root‐like structures, reduced colonisation, and vascular disorganisation. Summary Root nodules host nitrogen‐fixing bacteria and likely evolved through modifications of the lateral root program. Members of the NOOT‐BOP‐COCH‐LIKE transcriptional coregulator family suppress root identity in nodules ...
