Neuroprotective Mechanisms of Paeoniflorin in Parkinson's Models: Involvement of BDNF-Dependent PI3K/Akt and ERK/CREB Pathways.
(PubMed, Curr Issues Mol Biol)
- "A key innovation is the dual activation and coordinated activation of the two BDNF-dependent pathways: LY294002 abolished paeoniflorin-induced BDNF/PI3K/Akt activation, while PD98059 and ERK1/2 siRNA specifically suppressed paeoniflorin-triggered phosphorylation of ERK1/2, p90RSK, and CREB. Ultimately, paeoniflorin exerts robust neuroprotection against MPTP/MPP+ neurotoxicity by synergistically activating BDNF-downstream PI3K/Akt and ERK/CREB axes. This delineation of a dual-pathway mechanism provides novel insight into the pharmacological action of paeoniflorin and supports its potential as a multifaceted therapeutic agent for Parkinson's disease."

Study on the Role of FGF9/ERK/MMP9 Pathway in Age-Related Cataract and in (-)-Epigallocatechin-3-gallate Protecting Lens Epithelial Cells From Apoptosis.
(PubMed, Cell Biochem Funct)
- "ERK activation by TBHQ increased the viability of H2O2-treated HLE-B3 cells, whereas ERK inhibition with PD98059 attenuated the protective effects of EGCG and decreased MMP9 expression. Moreover, MMP9 knockdown increased cleaved caspase-9 expression and was accompanied by increased apoptosis in LECs. These findings suggest that the FGF9/ERK/MMP9 pathway is involved in oxidative stress-induced LEC apoptosis and may contribute, at least in part, to the protective effects of EGCG in experimental models of ARC."

WISP-3 promotes tumor-monocyte adhesion through a MEK/ERK-dependent miR-12131/ICAM-4 axis in lung adenocarcinoma.
(PubMed, Int J Med Sci)
- "Pharmacological inhibition of MEK using PD98059 or U0126, as well as direct inhibition of ERK with SCH772984, markedly attenuated WISP-3-induced ICAM-4 expression and THP-1 adhesion. Collectively, these results demonstrate that WISP-3 promotes ICAM-4-dependent monocyte adhesion through activation of the MEK/ERK pathway and subsequent suppression of hsa-miR-12131. This WISP-3/MEK/ERK/miR-12131/ICAM-4 axis provides new insight into tumor-immune interactions in NSCLC and highlights potential therapeutic targets."

Neuregulin attenuates diaphragm muscle protein degradation via an intricate signaling network.
(PubMed, Front Physiol)
- "NRG effects were significantly blunted by rapamycin (p < 0.05 compared to NRG alone), but not by LY294002 or PD98059. We suggest that both the PI3K/Akt and MAP kinase pathways are important for NRG effects on protein degradation, but that mTOR may be a critical modulator of these effects and thus of protein balance in skeletal muscle."

Extracellular Signal-Regulated Kinase and Reactive Oxygen Species Regulate PD-L1 to Promote Migration and Proliferation of Triple-Negative Breast Cancer MDA-MB-231 Cells.
(PubMed, Oncol Res)
- " The ERK inhibitor (PD98059) suppressed MDA-MB-231 cell migration but not proliferation, whereas PD-L1 siRNA and the ROS scavenger dithiothreitol (DTT) reduced both cell migration and proliferation...Similar observations were noted in another TNBC cell line, Hs578T, which exhibits motility, but not in MDA-MB-453 cells, which lack motility. Since PD-L1 appears to function downstream of ERK and ROS and is required for TNBC progression, co-targeting both ERK and ROS signaling pathways may represent a promising therapeutic strategy for TNBC."

Identification of two MAPK transcripts in the colonial ascidian Botryllus schlosseri: involvement in immune and stress responses and potential roles in colony growth.
(PubMed, Fish Shellfish Immunol)
- "Since phagocytic activity is essential for the cyclical renewal of the colony throughout the blastogenetic cycle, we also investigated the effects of colony exposure to MAPK inhibitors, PD98059 and SP600125, targeting the ERK and JNK signalling pathways, respectively. The inhibition of MAPK activity altered colony development and modulated the expression of genes associated with oxidative stress protection (sod, gpx-5) and stress granule dynamics (tiar, ttp), processes involved in post-transcriptional regulation. These findings suggest that MAPK signalling is indispensable for the proper progression of the blastogenetic cycle in B. schlosseri, integrating oxidative stress defence and post-transcriptional control to maintain colony homeostasis."

MEK-ERK inhibition enhances synaptic input-output coupling and neuronal excitability in the rat dentate gyrus: association with site-specific Kv4.2 phosphorylation.
(PubMed, Cogn Neurodyn)
- "Inhibition of MEK with PD98059 did not alter basal field excitatory postsynaptic potential (fEPSP) slopes but significantly increased population spike (PS) amplitudes. Site-specific Kv4.2 phosphorylation at Thr602/Thr607, together with reduced total Kv4.2 expression, may contribute to the observed E-S potentiation. This mechanism may underlie hyperexcitability associated with neurological disorders."

Role of (pro) renin receptor in adriamycin-induced cardiomyopathy.
(PubMed, Int J Cardiol Heart Vasc)
- "(Pro) renin receptor (PRR) is a newly recognized element of the renin-angiotensin system associated with cardiovascular diseases. PD98059 attenuated cardiomyocyte fibrosis, inflammatory response, apoptosis, and reduced NOX2 abundance and NOX activity in ADR-treated NRCFs. PRR is involved in the pathological progression of ADR-CM, and inhibition of PRR may represent a novel and promising therapeutic strategy for ADR-CM."

Prenatal and Lactational Exposure to Polystyrene Nanoplastics Induces Lipid Accumulation in Vascular Smooth Muscle Cells of Male Offspring via the MAPK/ERK/UHRF1 Signaling Pathway.
(PubMed, Cardiovasc Toxicol)
- "Further pharmacological inhibition of ERK using PD98059 significantly attenuated both UHRF1 expression and lipid accumulation, providing additional evidence supporting the critical role of the MAPK/ERK/UHRF1 axis in PS-NPs-induced lipid dysregulation. Additionally, siRNA-mediated knockdown of UHRF1 alleviated PS-NPs-induced lipid accumulation, supporting the pivotal role of UHRF1 in the cellular response to PS-NPs exposure. Overall, these findings demonstrate that prenatal and lactational exposure to PS-NPs disrupts early vascular lipid homeostasis in male offspring by activating the MAPK/ERK/UHRF1 signaling pathway in vascular smooth muscle cells."

C/EBP alpha agonist ICCB280 overcomes doxorubicin resistance in osteosarcoma through mitochondrial dynamics-dependent GREM1-MAPK activation.
(PubMed, Cell Death Dis)
- "The resistance of doxorubicin (DOX), the first-line chemotherapeutic drug for osteosarcoma (OS), stands as a pivotal obstacle in the effective treatment of OS. When ICCB280 and PD98059 are co-administered, the activation of GREM1 by C/EBPα and the inhibition of ERK phosphorylation are intensified. This suppresses OPA1 expression, promotes mitochondrial fission, and effectively counteracts chemotherapy resistance in osteosarcoma."

Neurotensin Receptor 1 Regulates HER4 Tyrosine Phosphorylation in Lung Cancer Cells.
(PubMed, Biology (Basel))
- "Adding NTS to NSCLC cells increased both P-ERK and P-AKT, which were inhibited by PD98059 and LY294002, respectively. The growth of NCI-H522 or NCI-H661 cells was stimulated by NTS or neuregulin 1 (NRG1), a HER4 ligand, but inhibited by SR48692 or ibrutinib. The results indicate that NTSR1 regulates HER4 transactivation, thereby increasing the proliferation of lung cancer cells."
