Cholecystokinin-mediated RhoGDI phosphorylation via PKCα promotes both RhoA and Rac1 signaling. [PDF]
RhoA and Rac1 have been implicated in the mechanism of CCK-induced amylase secretion from pancreatic acini. In all cell types studied to date, inactive Rho GTPases are present in the cytosol bound to the guanine nucleotide dissociation inhibitor RhoGDI ...

The Functional Significance of the Rho/Rho-Kinase Pathway in Human Erythrocytes
OBJECTIVE: Erythrocyte deformability, which can be influenced by various intracellular signaling mechanisms, such as nitric oxide, cAMP, cGMP, and protein kinases, is the most important physiological factor providing the blood flow in microcirculation ...

α8β1 integrin regulates nutrient absorption through an Mfge8-PTEN dependent mechanism. [PDF]
Coordinated gastrointestinal smooth muscle contraction is critical for proper nutrient absorption and is altered in a number of medical disorders. In this work, we demonstrate a critical role for the RGD-binding integrin α8β1 in promoting nutrient ...

Emerging role of ARHGAP29 in melanoma cell phenotype switching
This study gives first insights into the role of ARHGAP29 in malignant melanoma. ARHGAP29 was revealed to be connected to tumor cell plasticity, promoting a mesenchymal‐like, invasive phenotype and driving tumor progression. Further, it modulates cell spreading by influencing RhoA/ROCK signaling and affects SMAD2 activity. Rho GTPase‐activating protein

Wnt5a causes ROR1 to complex and activate cortactin to enhance migration of chronic lymphocytic leukemia cells. [PDF]
Chronic lymphocytic leukemia cells (CLL) migrate between the blood and lymphoid tissues in response to chemokines. Such migration requires structured cytoskeletal-actin polymerization, which may involve the protein cortactin. We discovered that treatment

Colorectal cancer (CRC) mortality is highest in aged males. Pre‐clinical data comparing CRC i.p. metastasis in cohorts of young and aged, male and female mice support these finding. Bottom‐up proteomics of peritoneal mesothelial cells identified PTP4A1 as highly expressed in aged males and a role for PTP4A1 in heterotypic cell:cell adhesion was ...

Janus kinase 2 inhibition by pacritinib as potential therapeutic target for liver fibrosis
Diagram of the activation of the profibrotic and procontractile Janus kinase 2 (JAK2)/Ras homolog family member A/Rho‐kinase pathway and the inhibition of phosphorylated JAK2 by pacritinib to inhibit hepatic stellate cell activity. Abstract Background and Aims Janus kinase 2 (JAK2) signaling is increased in human and experimental liver fibrosis with ...

RhoA Is a Crucial Regulator of Myoblast Fusion
Satellite cells (SCs) are adult muscle stem cells that are mobilized when muscle homeostasis is perturbed. Here we show that RhoA in SCs is indispensable to have correct muscle regeneration and hypertrophy.

Rho-A prenylation and signaling link epithelial homeostasis to intestinal inflammation [PDF]
Although defects in intestinal barrier function are discussed as a key pathogenic factor in patients with inflammatory bowel diseases (IBD), the molecular pathways driving disease-specific alterations of intestinal epithelial cells (IECs) are largely ...

Abstract Rheumatoid arthritis (RA) is a common autoimmune disease with bone destruction as the core pathology, which belongs to the category of “impediment disease” in traditional Chinese medicine (TCM), and its etiology and pathogenesis are still not completely clear.
