SP600125

Pharmacological inhibition of integrin α2β1 (BTT-3033), FAK (PF573228) and JNK (SP600125) effectively abrogated PDA-induced malignant phenotypes and restored chemosensitivity to cabazitaxel, cisplatin, docetaxel, curcumin, and enzalutamide. Collectively, these findings identify PDA-coated surfaces as a simple, efficient, and reductionist in vitro platform for studying adhesion-mediated signaling and phenotypic plasticity in PC cells, while acknowledging that further validation in three-dimensional (3D) and patient-derived models will be required to establish in vivo relevance.

As the nuclear translocation of RB1CC1 was promoted by the JNK signaling pathway, SP600125, a JNK inhibitor, prevented the MPD-induced RB1CC1 nuclear translocation. In summary, MPD induced the dissociation of RB1CC1 from DRMs and its subsequent nuclear translocation, contributing to ferroptosis of prostate cancer cells.

The autophagy inhibitor chloroquine enhanced the pro-apoptotic effect of B. rynchopetera. Additionally, the c-Jun N-terminal kinase(JNK) inhibitor(SP600125) suppressed the activation of the JNK pathway as well as B. rynchopetera-induced apoptosis and autophagy. In conclusion, B. rynchopetera activates the MAPK/JNK pathway to induce apoptosis and autophagy, thereby exerting the therapeutic effect on LUAD.

WB was used to assess activation of the c-Jun N-terminal kinase (JNK)/p38 mitogen-activated protein kinase (MAPK) pathway, and pathway dependence was examined using the ROS scavenger N-Acetylcysteine (NAC) and the JNK inhibitor SP600125. It exerts anti-tumor effects by inducing oxidative stress and activating the JNK/p38 MAPK pathway in a ROS-dependent manner. These findings suggest that CSRNP1 may serve as a potential therapeutic target in the management of HCC.

Inhibition of JNK with SP600125 reversed PPD-induced apoptosis, indicating that JNK signaling plays a critical role...Our findings revealed that PPD exerts potent anti-melanoma effects by directly targeting MLK3 and activating the MLK3-JNK signaling pathway, leading to apoptosis. These results provide novel insights into the molecular mechanism of PPD and suggest its potential as a therapeutic agent for melanoma treatment.

Pharmacological modulators (SC79, SP600125) were used to verify pathway roles. UA sensitizes BCa to GEM chemotherapy by promoting apoptosis, mediated through PI3K/AKT inactivation and JNK activation. These findings highlight UA as a promising adjunct to GEM therapy, warranting further clinical exploration.

Treatment with SP600125 (JNK inhibitor) or SB203580 (p38 MAPK inhibitor) effectively recused JNK and p38 activation. Both inhibitors also reduced the apoptotic cell population, which was upregulated by USP42 silencing. These findings highlight USP42 promotes breast cancer progression by reducing JNK and p38 activation and inhibiting apoptosis, suggesting its potential as a therapeutic target in breast cancer treatment.

Further ranking according to their blood-brain barrier permeability, as well as structural and transcriptomic similarities to known anti-GBM drugs, revealed SP600125, vemurafenib, FG-7142, dibenzoylmethane, and phensuximide as the most promising for GMT inhibition. In vitro validation showed that SP600125, which is most closely associated with GMT-related hub genes, effectively inhibited TGF-β1- and chemical hypoxia-induced GMT in U87 GBM cells by reducing morphological changes, migration, vasculogenic mimicry, and mesenchymal marker expression. These results clearly demonstrate the applicability of connectivity mapping as a powerful tool to accelerate the discovery of effective GMT-targeting therapies for GBM and significantly expand our understanding of the antitumor potential of SP600125.

Elp3 may be involved in GC progression by activating the JNK/MAPK pathway through histone acetylation.

A specific pharmacological inhibitor of JNK (SP600125) significantly attenuated CSE-induced RUNX2 and Galectin-3 expression, and also reversed CSE-driven EMT marker alterations, suppressed transcriptional EMT perturbations, and reduced proinflammatory cytokines, including monocyte chemoattractant protein-1 (MCP-1), interleukin-8 (IL-8), and tumor necrosis factor-alpha (TNF-α). In conclusion, this study identifies that ROS/JNK/RUNX2/Gal-3 axis drives CS-induced oncogenic plasticity, suggesting that targeted inhibition of this pathway could be an effective strategy for mitigating CS-related LC progression.

HYXPT exerts its therapeutic effects on PLGC by regulating the JNK/c-Jun/Slug signaling pathway, thereby inhibiting EMT during PLGC progression.

This study aimed to investigate the effects of DAPA on nicotine (NIC)-induced apoptosis in human kidney proximal tubular epithelial (HK-2) cells.MethodsHK-2 cells were treated with NIC, DAPA or selective mitogen-activated protein kinase (MAPK) inhibitors (SP600125 and SB203580). Dapagliflozin and MAPK attenuations regulate the expression of oxidant and antioxidant proteins, reducing intracellular ROS and MitoSOX overproduction and thereby alleviating mitochondrial dysfunction and ER stress. Both agents also significantly reduced pro-inflammatory cytokine levels, including TNF-α and IL-1β.ConclusionsThese findings suggest that DAPA protects HK-2 cells from NIC-induced apoptosis by modulating the ASK1/p38/JNK MAPK signalling pathway, reducing oxidative stress and alleviating inflammation.
