Redox environment modulates aggregation of ataxin‐3 in vitro — Implications for drug screening of cysteine‐rich proteins

The FEBS Journal, EarlyView.
Redox environment modulates in vitro aggregation of Ataxin‐3, the protein implicated in spinocerebellar ataxia type 3. Reducing conditions stabilize native monomers and prevent aggregation, whereas oxidative conditions promote the formation of non‐native conformers and disulfide‐linked oligomers within the Josephin domain (JD).

Role of human RNase 7 in neuronal and glial cell models: moving towards an unexpected new functional link

The FEBS Journal, EarlyView.
Human RNase 7 is known to exert antimicrobial activity in epithelial tissues. Here, using SH‐SY5Y and U‐87 MG, neuroblastoma and glioblastoma cell lines, respectively, we found that RNase 7 enhances immune responses to LPS stimulation by reducing the expression of pro‐inflammatory cytokines, nitric oxide, and ROS.

Exercise‐related microRNAs in Caenorhabditis elegans regulate calcium homeostasis and mitochondrial dynamics: Conserved pathways, divergent microRNAs

The FEBS Journal, EarlyView.
Exercise‐related microRNAs cel‐miR‐249‐3p and cel‐miR‐77‐5p in C. elegans regulate lifespan, fitness, mitochondrial morphology and membrane potential. Although lacking direct mammalian orthologs, H2O2‐induced microRNAs mmu‐miR‐181a‐5p and mmu‐miR‐378a‐3p regulate myogenesis, autophagy, mitochondrial content and respiration in murine myoblasts ...

The tryptophan prenyltransferase ComQ from Bacillus subtilis 168 can prenylate daptomycin at Trp1

The FEBS Journal, EarlyView.
ComQ168 from Bacillus subtilis 168 catalyzes C‐terminal tryptophan farnesylation of ComX to generate a competence‐inducing pheromone. Recombinant ComQ168 also modifies cyclic peptides, including Daptomycin, likely at the N‐terminal tryptophan. Structural modeling highlights a C‐terminal binding region, supporting substrate promiscuity and establishing ...

Flavobacterium oreochromis From Farmed Tambaqui (Colossoma macropomum): Insights Into Genetic, Phenotypic and Pathogenic Diversity

Journal of Fish Diseases, EarlyView.
ABSTRACT Flavobacterium spp. are the etiological agents of columnaris disease. Although there is evidence that columnaris poses a significant threat to the farming of tambaqui (Colossoma macropomum), there remains a large gap in understanding the genetic and phenotypic diversities of columnaris‐causing bacteria (CCB).

The HaMYB22–HaGST3.2 module mediates salt stress response in sunflower

Journal of Integrative Plant Biology, EarlyView.
The transcription factors HaMYB22, HaMYB120, and HaMYB121 cooperatively activate the transcription of the glutathione S‐transferase gene HaGST3.2, thereby facilitating the removal of reactive oxygen species induced by salt stress in sunflowers and improving their salt tolerance.

SlGRF1 mediates gibberellin signaling to control cut‐budding in tomato

Journal of Integrative Plant Biology, EarlyView.
Upon wounding, cytokinin increases to initiate callus formation. Gibberellin enhances this, but later blocks bud formation by suppressing SlGRF1. Wounding‐induced protein SlGRF1 triggers buds via NAM1, EPF4, and ER2. Hormonal shifts control cut‐budding phases.

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

Journal 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.

Divergent roles of ent‐kaurene oxidase paralogs in rice momilactone biosynthesis

Journal of Integrative Plant Biology, EarlyView.
Rice contains a five‐gene tandem array of genes encoding members of the ent‐kaurene oxidase (KO) family, with OsKOL4 and OsKOL5 playing divergent roles in momilactone metabolism, but both acting in the production of antifungal and antibacterial phytoalexins, which are important for disease resistance.
