Rho GTPase activation.

, 2012
(A) Schematic representation of the Rho GTPase activation cycle. (1) The GTP-bound active state is generated by guanine exchange factors (GEFs), promoting the exchange of GDP for GTP.

SERPINE1 Alternative Polyadenylation Influences Gastric Cancer Prognosis via N6‐Methyladenosine Modification

Cancer Science, EarlyView.
Multi‐omics integration of the transcriptomic APA landscape and m6A modifications identifies key prognostic genes. Their biological functions and molecular mechanisms in promoting tumor progression are comprehensively validated through in vitro assays. ABSTRACT Alternative polyadenylation (APA) and N6‐methyladenosine (m6A) methylation are critical post‐

Rho GTPase and Rho Kinase Signaling in Tissue Contractility and Intraocular Pressure Regulation

Frontiers in Bioscience-Landmark
The Rho GTPase and Rho kinase (ROCK) signaling pathway is essential for cellular mechanics, acting as key regulators of the actin cytoskeleton and actomyosin contractility in various cell types and tissues. Rho GTPases, functioning as molecular switches,

Long Non‐Coding RNA, Like NEAT1 and MALAT1, in Asthma: Mechanisms and Therapeutic Potential

Clinical &Experimental Allergy, EarlyView.
Long non‐coding RNA, like NEAT1 and MALAT1, is emerging as a regulator of asthma‐related inflammation, airway remodelling, viral responses and cell death pathways, and are promising targets for future therapeutics. ABSTRACT Asthma affects millions worldwide. Long non‐coding RNA (lncRNA) are emerging as important factors in the pathophysiology of asthma

Macrophage Lipid Homeostasis Drives IVDD via a Senescence‐Dependent Impairment of Efferocytosis

Cell Proliferation, EarlyView.
Intervertebral disc degeneration (IVDD) has been a leading cause of low back pain and lacks disease‐modifying therapies. Although dysregulated disc lipid metabolism is implicated, its impact on the immune microenvironment, particularly macrophages, remains unknown.

Mechanical stiffness orchestrates distinct regulation of MRTFs and YAP/TAZ transcriptional cofactors in hepatocytes

The FEBS Journal, EarlyView.
MRTFs and YAP/TAZ proteins, or mechanosensitive transcriptional cofactors (MRTcoF), regulate common genes associated with cellular contractility and immune cell infiltration. Their differential regulation in response to stiffness is linked to changes in hepatocyte's aspect ratio. MRTFB does not undergo nuclear translocation under these conditions. This

Inhibition of Rho GEFs attenuates pulmonary fibrosis through suppressing myofibroblast activation and reprogramming profibrotic macrophages

Cell Death and Disease
Idiopathic pulmonary fibrosis has a poor prognosis, with existing medications only partially alleviating symptoms, highlighting the urgent need for new therapeutic approaches.

CD36‐mediated lipid rewiring in the metabolic adaptation of tumour ecosystems

The FEBS Journal, EarlyView.
Nutrient deprivation drives a lipid‐centric shift in tumour metabolic symbiosis and signalling network. CD36 functions as a bidirectional bridge, transferring fatty acids from stromal donors (adipocytes, CAFs) to the ecosystem tumour‐ and microenvironment‐dependently.

A posttranslational proteomic survey of a single anatomically preserved human 20‐week postconception brain

Journal of Anatomy, EarlyView.
A well‐preserved 20 post‐conception week human brain was obtained and finely dissected into 18 anatomically distinct regions, including the pia mater. Each region underwent in‐depth proteomic analysis, encompassing both total protein content and post‐translational modifications.

Patterning of the cell cortex by Rho GTPase Dynamics [PDF]

The Rho GTPases — RHOA, RAC1 and CDC42 — are small GTP binding proteins that regulate basic biological processes such as cell locomotion, cell division and morphogenesis by promoting cytoskeleton-based changes in the cell cortex.
