This study demonstrates that YFBP exerts significant anti-OC therapeutic effects by modulating the inflammatory TME and activating the JNK/c-Jun pathway. Our findings provide a pharmacological basis for the traditional use of YFBP and highlight its potential as a promising candidate phytomedicine for OC therapy.

However, the JNK inhibitor (JNK-IN-8) suppressed the narciclasine-induced increase in cleaved caspase expression and apoptosis, whereas ERK and p38 inhibitors had no effect. These findings highlight the central role of JNK signaling in mediating extrinsic and intrinsic apoptotic pathways in osteosarcoma cells treated with narciclasine.

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.

These results suggest that BMP-7 might inhibit PON-induced cardiotoxicity. Furthermore, our findings pave the way for future translational studies with BMP-7, which can demonstrate the therapeutic potential of BMP-7 in a clinical setting.

Notably, claudin-11, an oligodendrocyte-specific, tight junction protein, was identified as a novel phospho-target that was highly reduced upon DJNKI-1 treatment. Together, these findings highlight potential molecular markers of anxiolytic response and suggest synaptic and metabolic interplay in mood regulation.

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.

These findings indicate that γT3 and δT3 inhibit HCC2998 cell proliferation by activating the DDR pathway, highlighting their potential as therapeutic agents to overcome cell cycle arrest resistance in CRC. This study provides critical insights into the molecular actions of γT3 and δT3, supporting their further investigation as promising candidates for CRC intervention.
