Epidermal Growth Factor Induces Vasoconstriction Through the Phosphatidylinositol 3-Kinase-Mediated Mitogen-Activated Protein Kinase Pathway in Hypertensive Rats

Journal of Pharmacological Sciences, 2006
.: We investigated whether increased contractile responsiveness to epidermal growth factor (EGF) is associated with altered activation of mitogen-activated protein kinase (MAPK) in the aortic smooth muscle of deoxycorticosterone acetate (DOCA)-salt ...

The PIK3CA H1047R Mutation Confers Resistance to BRAF and MEK Inhibitors in A375 Melanoma Cells through the Cross-Activation of MAPK and PI3K–Akt Pathways

Pharmaceutics, 2022
The targeting of the Mitogen-Activated Protein Kinase (MAPK) signalling pathway in melanoma improves the prognosis of patients harbouring the V-Raf Murine Sarcoma Viral Oncogene Homolog B1 (BRAF) mutation.

Mechanisms of parasite‐mediated disruption of brain vessels

FEBS Letters, EarlyView.
Parasites can affect the blood vessels of the brain, often causing serious neurological problems. This review explains how different parasites interact with and disrupt these vessels, what this means for brain health, and why these processes matter. Understanding these mechanisms may help us develop better ways to prevent or treat brain infections in ...

Feasibility of a ctDNA multigenic panel for non‐small‐cell lung cancer early detection and disease surveillance

Molecular Oncology, EarlyView.
Plasma‐based detection of actionable mutations is a promising approach in lung cancer management. Analysis of ctDNA with a multigene NGS panel identified TP53, KRAS, and EGFR as the most frequently altered, with TP53 and KRAS in treatment‐naïve patients and TP53 and EGFR in previously treated patients.

Evaluation of 2-(4-Chlorophenyl)-4-(4-fluorophenyl)-5-pyridin-4-yl-1,2-dihydropyrazol-3-one as a p38 MAPK inhibitor in MCF-7 and MDA-MB-231 breast cancer cell lines

Al-Mustansiriyah Journal of Pharmaceutical Sciences
Breast cancer is a diverse disease with high mortality rates, often due to metastasis. Breast cancer subtypes vary by the expression of progesterone receptor, human epidermal growth factor receptor 2, and estrogen receptor.

3′,5′‐Cyclic Guanosine Monophosphate Activates Mitogen‐Activated Protein Kinase in Rat Pinealocytes [PDF]

Journal of Neurochemistry, 1999
Abstract : The role of 3′,5′‐cyclic guanosine monophosphate (cGMP) in the activation of mitogen‐activated protein kinases (MAPKs) was investigated in rat pinealocytes. Treatment with dibutyryl cGMP (DBcGMP) dosedependently increased the phosphorylation of both p44 and p42 isoforms of MAPK.

The neural crest‐associated gene ERRFI1 is involved in melanoma progression and resistance toward targeted therapy

Molecular Oncology, EarlyView.
ERRFI1, a neural crest (NC)‐associated gene, was upregulated in melanoma and negatively correlated with the expression of melanocytic differentiation markers and the susceptibility of melanoma cells toward BRAF inhibitors (BRAFi). Knocking down ERRFI1 significantly increased the sensitivity of melanoma cells to BRAFi.

Big Mitogen-Activated Protein Kinase 1 Protects Cultured Rat Aortic Smooth Muscle Cells From Oxidative Damage

Journal of Pharmacological Sciences, 2011
.: Oxidative stress is considered a major mediator of arteriosclerosis. In vascular smooth muscle cells, oxidative stress–induced cell death (including apoptosis) is probably related to arterial calcification in arteriosclerosis.
