However, how severe endothelium-denuded injury is rapidly repaired remains unknown. Given the common biological properties between endothelial cells and circulating monocytes, we aimed to examine whether blood monocytes are involved in endothelium wound healing. The in vivo common carotid artery endothelium-denuded (CCAED) model was established through a wire-induced injury. Monocyte adhesion was assessed using immunofluorescence and a parallel plate flow chamber. We initially observed that the circulating monocyte-mediated endothelialization was better downstream of kinase 3 deficient mice (DOK3^-/-) than that of wild-type (WT) mice following induction of the CCAED model. Rapid endothelialization increased endothelial integrity, prevented coagulation, and decreased thrombosis. Mechanistically, following endothelium-denuded injury, monocyte chemoattractant protein 1 (MCP1) disassociated from DOK3 and C-C chemokine receptor type 2B (CCR2B), increased the intracellular Ca²⁺ concentration, and promoted adhesion in circulating monocytes. However, this process was inhibited by the CCR2B inhibitor INCB3344. Moreover, the adhesive functions of circulating monocytes isolated from DOK3^-/- mice were stronger than those from WT mice. Furthermore, adhered monocytes expressed endothelial-specific markers and compensated for endothelium-dependent vasorelaxation in WT mice. Similarly, these effects were enhanced in DOK3^-/- mice. Bindarit, a selective MCP1 inhibitor, suppressed endothelialization following CCAED surgery in WT mice but not in DOK3^-/- mice. In conclusion, endothelialization mediated by circulating monocytes repairs endothelium-denuded injury to compensate for endothelial functions through MCP1/DOK3/CCR2B/Ca²⁺ signaling. Our findings indicate that circulating monocyte adhesion is an important endothelial wound healing mechanism.</p>","PeriodicalId":93896,"journal":{"name":"Biochimica et biophysica acta.

However, resistance to these drugs emerges as a significant impediment to the management of renal cancer. MICAL-L2 plays a pivotal role in cytoskeleton rearrangement. This study sought to elucidate the clinical relevance of MICAL-L2 in KIRC and its regulatory mechanism driving cancer progression and resistance to therapy. TCGA data mining was utilized to assess the expression of MICAL-L2 in samples from patients with KIRC. Kaplan-Meier analysis and immunohistochemistry were employed to explore the clinical significance of MICAL-L2. In vitro experiments, including assays for wound healing and Transwell migration, CCK-8, EDU staining, RT-PCR, flow cytometry, and co-immunoprecipitation analysis were conducted to investigate the effects of MICAL-L2 on the drug sensitivity of KIRC cells and to elucidate the molecular mechanisms involved. The results showed that MICAL-L2 was overexpressed in KIRC tissues. High levels of MICAL-L2 were associated with poor survival and a poor response to drug therapy among patients with KIRC. Overexpression of MICAL-L2 stimulated cell migration, proliferation, and rendered KIRC cells insensitive to sunitinib and everolimus, two traditional therapies for KIRC. Furthermore, MICAL-L2 overexpression accelerated cancer progression and resistance to therapy in KIRC cells by interacting with its downstream regulator α-actinin-4 (ACTN4) in a Rab13-dependent manner, which reduced the degradation of ACTN4, leading to increased Vimentin expression. All these findings indicate that MICAL-L2 plays a crucial role in the progression of KIRC and suggest that MICAL-L2 may serve as a potential therapeutic target for KIRC treatment.</p>","PeriodicalId":93896,"journal":{"name":"Biochimica et biophysica acta.

Achondroplasia (ACH), the most common form of genetic dwarfism in humans, is caused by a gain-of-function mutation in fibroblast growth factor receptor 3 (FGFR3), a receptor tyrosine kinase that activates downstream mitogen-activated protein kinase (MAPK) and signal transducer and activator of transcription (STAT) signaling pathways. The first precision drug approved for the treatment of ACH in children, the C-type natriuretic peptide analog vosoritide, antagonizes the MAPK pathway, while there are currently no effective and safe medications targeting the STAT1 pathway.

KY-065 inhibited CDK8 with high affinity in vitro by competing with ATP.

Moreover, daily administration of 10 mg/kg KY-065 to Fgfr3^Ach mice (yielding a peak concentration of 22.0 ± 1.47 μM in plasma) resulted in significant elongation of long bone and improved growth plate cytoarchitecture.

First, we identified extensive fibrotic changes in inferior oblique (IO) muscles in PIOOA patients compared to normal controls. A strong positive correlation was clinically established between the severity of PIOOA and the expression of collagen type I alpha 1 chain (COL1A1). COL1A1 levels correlate with preoperative and postoperative clinical grading of PIOOA and the degree of fundus deviation, as measured by disk-foveal angle (DFA). Moreover, immunofluorescence in IO muscle sections of PIOOA patients confirmed activation of fibro/adipogenic progenitors (FAPs) and suggested increased activation of YAP. Interestingly, the TGFβ signaling pathway also exhibited activation, with a notable increase observed in the expression of TGFβ2 in the PIOOA group. Subsequently, we first isolated FAPs from human IO muscles and validated these findings. In vitro, YAP overexpression promoted the differentiation of FAPs into myofibroblasts, exacerbating fibrotic changes. However, knockdown of YAP inhibited the activation of FAPs and fibrogenesis induced by TGFβ2. More importantly, we found TGFβ2 treatment promoted the activation of YAP simultaneously, and the overexpression or inhibition of YAP also affected TGFβ2 production and Smad phosphorylation, indicating a close connection between the two. Remarkably, verteporfin was observed to block both pathways effectively. Taken together, these findings suggest that the YAP-TGFβ-SMAD signaling cascade plays a key role in the pathophysiology of PIOOA through FAP-mediated fibrosis. Targeting these pathways may therefore provide a potential therapeutic strategy for managing PIOOA by alleviating muscle fibrosis.</p>","PeriodicalId":93896,"journal":{"name":"Biochimica et biophysica acta.
