General description

A cell-permeable pyrazolylthiazolo-isobutyramide compound that acts as a potent LIM kinase inhibitor (IC50 = 7 and 8 nM against LIMK1 and LIMK2, respectively) and effectively suppresses cellular cofilin phosphorylation (IC50 ~ 1 µM in A549 and MDA-MB-231 cultures) without affecting tubulin polymerization or inducing cytotoxicity (EC50 >10 µM in A549 proliferation and colony formation assays). Shown to effectively destabilize F-actin structure in MDA-MB-231 breast cancer cells (3 to 10 µM) with concomitant blockage of invadopedia-mediated ECM degradation (13% and 10% of control, respectively, by 3 and 10 µM inhibitor) and invasion (45% and 7% of control invasion rate, respectively, by 3 and 10 µM inhibitor). Although reported to exhibit affinity toward AMPKα1 and AMPKα2 in T7 phage-based competition binding studies, inhibitory activity of LIMKi 3 against AMPKα1/2 is not yet directly demonstrated.

The mechanical properties of the extracellular environment are interrogated by cells and integrated through mechanotransduction. Many cellular processes depend on actomyosin-dependent contractility, which is influenced by the microenvironment's stiffness. Here, we explored the influence of substrate stiffness on the proteome

LIM kinases (LIMK1/2) are LIM domain-containing serine/threonine/tyrosine kinases that mediate multiple cellular processes in mitosis. In the present study, we explored the functional roles and potential signaling pathway of LIMK1/2 during mouse oocyte meiosis. Disruption of LIMK1/2 activity and expression

Cell migration is driven by local membrane protrusion through directed polymerization of F-actin at the front. However, F-actin next to the plasma membrane also tethers the membrane and thus resists outgoing protrusions. Here, we developed a fluorescent reporter to monitor
