Presynaptic Congenital Myasthenic Syndromes

Muscle &Nerve, EarlyView.
ABSTRACT Presynaptic congenital myasthenic syndromes (CMS) encompass a large number of rare neurologic disorders caused by impaired release of acetylcholine (ACh) from motor nerve terminals. There are two main groups of presynaptic CMS: one in which the amount of ACh in synaptic vesicles (SV) is diminished and another in which the mechanism of synaptic

Gene turnover in the common ancestor of all C4 grasses

PLANTS, PEOPLE, PLANET, EarlyView.
Understanding how plants evolve more efficient photosynthesis is important in a warming world where improving crop productivity and resilience is a global priority. By generating the first reference genomes for an early‐diverging group of grasses called the Aristidoideae, we were able to reconstruct the genetic makeup of the last common ancestor of all

Rho GTPases in the Physiology and Pathophysiology of Peripheral Sensory Neurons

Cells, 2019
Numerous experimental studies demonstrate that the Ras homolog family of guanosine triphosphate hydrolases (Rho GTPases) Ras homolog family member A (RhoA), Ras-related C3 botulinum toxin substrate 1 (Rac1) and cell division cycle 42 (Cdc42) are ...

Rho GTPases in hematopoiesis and hemopathies

Blood, 2010
AbstractRho family GTPases are intracellular signaling proteins regulating multiple pathways involved in cell actomyosin organization, adhesion, and proliferation. Our knowledge of their cellular functions comes mostly from previous biochemical studies that used mutant overexpression approaches in various clonal cell lines.

Baicalein Sensitizes Radioresistant BT549 and MCF7‐R Breast Cancer Cells by Modulating Rac1 Signaling

Phytotherapy Research, EarlyView.
ABSTRACT Radioresistance remains a key barrier in breast cancer (BC) treatment. Baicalein, a flavonoid from Scutellaria baicalensis, has shown potential to enhance radiosensitivity. This study investigates its efficacy and mechanism in radioresistant BC models. Radioresistant BC cell models were established via fractionated irradiation and validated by

Fast-cycling Rho GTPases [PDF]

Small GTPases, 2018
The Rho GTPases were discovered more than 30 years ago, and they were for a long time considered to follow simple cycling between GDP-bound and GTP-bound conformations, as for the Ras subfamily of small GTPases. The Rho GTPases consist of 20 members, but at least 10 of these do not follow this classical GTPase cycle.

Harnessing the nonthermal effects of ultrasound for cancer treatment: From mechanisms to applications

Smart Molecules, EarlyView.
Nonthermal ultrasound transforms acoustic energy into diverse therapeutic bioeffects through cavitation, mechanical stimulation, and physicochemical activation. This review discusses how acoustic parameters, biological mechanisms, and responsive materials interact to influence nonthermal ultrasound‐enabled cancer therapies. Mechanism‐guided engineering

Multi‐Omics Analysis Reveals Coordinated Adaptations in Genes, Metabolism, and Gut Microbiota Underpinning Herbivory in Lordiphosa Flies

Integrative Zoology, EarlyView.
Multi‐omics analysis reveals that herbivorous adaptation in Lordiphosa flies arises from coordinated interactions across the genome, transcriptome, and gut microbiota: genomic expansions of detoxification (e.g., cytochrome P450s) and carbohydrate metabolism gene families, transcriptomic upregulation of energy pathways like lipid oxidation and ...

Emollient Formulations and Skin Barrier Practices in the Context of Eczema and Food Allergy Prevention

Allergy, EarlyView.
ABSTRACT The skin is far from a passive shield; it functions as a dynamic “living barrier” whose structural and immunological integrity is paramount in preventing atopic dermatitis (AD) and the subsequent progression of the atopic march toward food allergy (FA).

Non‐canonical PKG1 regulation in cardiovascular health and disease

British Journal of Pharmacology, EarlyView.
It is well established that the cyclic GMP‐dependent protein kinase I (PKG1) is canonically activated by cyclic guanosine monophosphate (cGMP), enabling its regulation of vascular tone, cardiac function and smooth muscle homeostasis. However, diverse non‐canonical stimuli of PKG1 have also been identified.
