Cdc42 and aging of hematopoietic stem cells [PDF]

Current Opinion in Hematology, 2013
Hematopoietic stem cells (HSCs) continuously provide mature blood cells during the lifespan of a mammal. The functional decline in hematopoiesis in the elderly, which involves a progressive reduction in the immune response and an increased incidence of myeloid malignancy, is partly linked to HSC aging.

A Novel Pak1 Activator Ameliorates ER Stress for HFpEF Therapy

Advanced Science, EarlyView.
Chronic metabolic stress is a major contributor to HFpEF progression. Under prolonged metabolic stress, Pak1 activity becomes impaired, contributing to disrupted ER proteostasis, cardiomyocyte apoptosis, fibrosis, and diastolic dysfunction. Mechanistically, Pak1 overexpression activates the ERK1/2–MNK1–eIF4E signaling axis, promotes translational ...

Vav2 Is an Activator of Cdc42, Rac1, and RhoA [PDF]

Journal of Biological Chemistry, 2000
Vav and Vav2 are members of the Dbl family of proteins that act as guanine nucleotide exchange factors (GEFs) for Rho family proteins. Whereas Vav expression is restricted to cells of hematopoietic origin, Vav2 is widely expressed. Although Vav and Vav2 share highly related structural similarities and high sequence identity in their Dbl homology ...

A Robust Deep Temporal Causal Discovery Platform for Single‐Cell Gene Regulatory Network Reconstruction

Advanced Intelligent Discovery, EarlyView.
scTIGER2.0 is a deep‐learning framework that infers gene regulatory networks from single‐cell RNA sequencing data. By integrating correlation, pseudotime ordering, deep learning and bootstrap‐based significance testing, it reduces false positives and reveals directional gene interactions.

Monogenic deficiency in murine intestinal Cdc42 leads to mucosal inflammation that induces crypt dysplasia

Genes and Diseases
CDC42 controls intestinal epithelial (IEC) stem cell (IESC) division. How aberrant CDC42 initiates intestinal inflammation or neoplasia is unclear. We utilized models of inflammatory bowel diseases (IBD), colorectal cancer, aging, and IESC injury to ...

Relation of CDC42, Th1, Th2, and Th17 cells with cognitive function decline in Alzheimer's disease

Annals of Clinical and Translational Neurology, 2022
Objective Cell division cycle 42 (CDC42) regulates neurite outgrowth, neurotransmitter, and T help (Th) cell‐mediated neuroinflammation, while its clinical implication in Alzheimer's disease (AD) is not clear.

Spatial Regulation of Cdc42 During Cytokinesis [PDF]

Cell Cycle, 2007
Cdc42 GTPase plays a critical role in the establishment of cell polarity in most eukaryotic organisms. Cdc42 active state, as that of other GTPases, depends on the bound nucleotide. The protein with GTP is active, and only in this state can it interact with different target effector proteins.

First‐in‐human, phase I, randomized, safety, pharmacokinetic, food‐effect and pharmacodynamic study of a tyrosine kinase 2/Janus kinase 1 inhibitor, SDC‐1801

British Journal of Clinical Pharmacology, EarlyView.
Aim The purpose of this study is to evaluate safety, tolerability, pharmacokinetics (PK), food‐effect (FE) and pharmacodynamics (PD) of an oral tyrosine kinase‐2 (TYK2)/Janus kinase‐1 (JAK1) inhibitor, SDC‐1801, in healthy adult participants. Methods This first‐in‐human study randomized 95 male and female participants.

The role of Rho GTPases in facial morphogenesis

Developmental Dynamics, EarlyView.
The role of small GTPases, RHOA, RAC1, and CDC42 and pathway mediators is reviewed in the context of embryonic facial development. Lip fusion requires cytoskeletal remodeling during morphogenesis of the facial processes and during lip fusion. Fnm, frontonasal mass; lnp, lateral nasal process; mnp, medial nasal process; mxp, maxillary process; np, nasal

Secretopathies emerge as a new class of neurocristopathies

Developmental Dynamics, EarlyView.
Abstract Neural crest cells are a transient embryonic population of cells that give rise to a wide range of structures, including craniofacial cartilage and bone, peripheral neurons and glia, as well as components of the cardiac outflow tract, among others.
