Whole cell extracts (15 µg total protein) from indicated cell lines were resolved by 4-12% Bis-Tris gel electrophoresis, transferred to a PVDF membrane, and probed with 0.5 µg/mL of Purified anti-RhoA (clone A18230D) overnight at 4°C. Proteins were visualized by chemiluminescence detection using HRP Goat anti-mouse IgG (Cat. No. 405306) at a 1:3000 dilution. Direct-Blot™ HRP anti-GAPDH (Cat. No. 607904) was used as a loading control at a 1:50000 dilution. Western-Ready™ ECL Substrate Premium Kit (Cat. No. 426319) was used as a detection agent. Lane M: Molecular weight marker

    HeLa cells were fixed with Fixation Buffer (Cat. No. 420801) and permeabilized with ice-cold methanol for 10 minutes, and blocked with 5% FBS for 1 hour at room temperature. Cells were then stained with 5 µg/mL of Purified anti-RhoA (clone A18230D), followed by incubation with 2.5 µg/mL of Alexa Fluor® 647 Goat anti-mouse IgG (Cat. No. 405322) (panel A) for 1 hour at room temperature. Nuclei were counterstained with DAPI (Cat. No. 422801) (panel B). Images were merged (panel C). The images were captured by a Revvity Operetta CLS™ High Content Analysis System with a 63X objective. Scale bar: 50 µm

Description

RhoA, also known as Transforming protein RhoA, is a small GTPase that plays a crucial role in various cellular functions, such as cytoskeletal dynamics, cell migration, cell cycle regulation, and cellular development. It alternates between active and inactive states by binding to either GTP or GDP, respectively. It is primarily associated with the regulation of the cytoskeleton, particularly in the formation of actin stress fibers and actomyosin contractility. RhoA influences cell shape, polarity, and locomotion through its effects on actin organization. In human mesenchymal stem cells, RhoA activity switches the differentiation between adipogenesis or osteogenesis under actin-myosin-generated cytoskeletal tension via effector, Rho-kinases (ROCK). RhoA is essential for cleavage furrow formation and apical junctions in keratinocyte cell-cell adhesion. In the developing nervous system, p75NTR induces RhoA strengthening on actin assembly which limits growth cone mobility and neuronal elongation. RhoA is found overexpressed or hyperactivate in many types of cancers, including prostate cancer, gastric cancer, testis cancer, breast cancer, and chronic myeloid leukemia. A RhoA inhibitor targeting RhoA/Rho GTPase pathway aims to prevent breast cancer cell growth as a potential cancer drug.
