SCH772984

The ferroptosis activator RSL3 further attenuated tumor progression in both the knockdown and overexpression models, and combined treatment with the ERK inhibitor SCH772984 synergistically suppressed tumor growth in MIR4435-2HG-overexpressing xenografts. Notably, RSL3 diminished IQGAP3, Ras, ERK, CREB, and GPX4 levels across the experimental conditions. These findings indicate that MIR4435-2HG is a pivotal regulator of bladder cancer progression and ferroptosis via the IQGAP3/Ras/ERK/CREB axis, suggesting that MIR4435-2HG is a potential therapeutic target for intervention.

The interaction mechanism between circNFIB and IGF2BP3, which enhances L1CAM mRNA stability, was explored using RNA pulldown, mass spectrometry, RNA Immunoprecipitation (RIP), and actinomycin D assays...Finally, we verified circNFIB as a potential therapeutic target that can mitigate the anti-tumor effects of SCH772984 in vivo. RBMS1-mediated circNFIB interacts with IGF2BP3 to stabilize L1CAM mRNA, thereby activating the ERK/MAPK signaling pathway and promoting PNI in PDAC. This study provides a novel perspective on the molecular mechanisms underlying PNI in PDAC and lays the theoretical foundation for circNFIB as a potential therapeutic target for PDAC.

Several molecules-such as SCH772984, SCH900353, ulixertinib (BVD-523), CC-9003, KO-947, AZD0364, norathyriol, and FR180204-are currently in preclinical or clinical trial stages. This review also highlights recent advances in the design and synthesis of ERK inhibitors, emphasising their structural uniqueness and potential to inhibit mutant forms of ERK1/2. Finally, we discuss future directions for the development of ERK1/2 inhibitors as FDA-approved cancer therapeutics.

ALOXE3 promotes tumor progression in COAD through activation of the ERK1/2 signaling pathway and exhibits a strong association with the immune cell infiltration of the tumor microenvironment. It may serve as a prognostic biomarker and a potential therapeutic target in COAD. Further studies are warranted to validate its clinical applicability and explore its role in immunotherapeutic approaches.

After the specific inhibitor of ERK (SCH772984) was applied to thyroid cancer cells (BCPAP cells) overexpressing the BRD9 gene, the results suggested that SCH772984 reverses the high expression of MAPK/ERK pathway-associated protein in BCPAP cells (over-expression BRD9 cells). In conclusion, this study demonstrated that BRD9 was highly expressed in serum and malignant tumor tissues of thyroid cancer patients and further promoted the development of the malignant phenotype of thyroid cancer by activating the MAPK/ERK signaling pathway.

This work created a 12-gene signature based on NM, preliminary investigated immune infiltration in two risk categories, and discovered some possible anti-tumor medications. To sum up, our study findings offer fresh perspectives on the roles played by NM-associated genes in HCC development, prognosis, immunological response, and medication screening.

Mechanistically, transcriptome sequencing suggested that PFDN4 modulates HCC cell behavior through the MAPK/ERK signaling pathway, a result confirmed by Western blot and the use of the MAPK/ERK inhibitor SCH772984. Additionally, single-cell RNA sequencing data revealed that PFDN4 is primarily expressed in several immune cell types, including B cells, CD8 + Tex, DC, ILC, mast cells, macrophages, Tprolif, and Treg. In conclusion, our study demonstrates that PFDN4 is upregulated in HCC and drives tumor progression via the MAPK/ERK pathway, highlighting its potential as both a prognostic marker and therapeutic target for HCC.

ERK1/2 inhibitors may serve as novel molecular-targeted drugs for treating leukemia with NRAS mutations.

Colorectal fibroblasts promote malignant phenotype of CRC cells by activating the ERK signaling pathway.

ERK1/2 (ulixertinib and SCH772984), MEK1/2 (binimetinib), and PI3K (pictilisib) inhibitors inhibited growth of RRAS Q87L or RRAS2 Q72L cells more potently than cells expressing wildtype proteins. Oncogenic R RAS/RRAS2 mutations were detected in LUAD at a rate similar to some other well-characterized lung cancer drivers, such as HRAS/NRAS hotspot mutations or NRG1 fusions. Our study supports the inclusion of RRAS /RRAS2 into routine molecular diagnostic protocols for precision oncology and clinical development of pan-RAS inhibitors, such as RMC-6236, for patients with these driver mutations in order to fully realize the potential benefit of RAS-targeted therapies.

Sorafenib showed improved anti-tumor effects when co-treated with SCH772984, an extracellular signal-regulated kinase inhibitor. Our study suggests new therapeutic strategies for canine HCC, and these cell lines are valuable research materials for understanding HCC tumor biology in both humans and dogs.

ERK activation, SIRT1/PGC-1α-axis, and TP4-induced apoptosis were all significantly reversed by the ERK inhibitor SCH772984. Finally, the inhibitory effect of TP4 on tumor growth has been confirmed in a zebrafish bladder cancer xenotransplantation model. These findings suggest that TP4 may be a potential agents for human bladder cancer through apoptosis induction, ERK activation, and the promotion of SIRT1-mediated signaling pathways.
