TNF activates phosphorylated ERK. 22 / 22
| 22

reach
"TNF-alpha treatment increased pERK in small- and medium sized DRG neurons and to a lesser degree in large neurons."

reach
"TNF treatment caused an increase in p-ERK in differentiating myoblasts, which was accompanied with reduced MyoD and MyoG levels, as well as reduced MyHC protein content."

reach
"However, Digibind could attenuate or reduce TNFalpha induced endothelial adhesion molecule expression, but had no effects on TNFalpha induced pERK upregulation."

reach
"TNF-alpha and/or TGF-alpha stimulation increased phospho-MEK and phospho-ERK in cells transfected with TNFR1 siRNA."

reach
"Regional application of TNF-α at a nerve root causes pain hypersensitivity and increases pERK in small and medium DRG neurons [56]."

reach
"In contrast, neither the steady-state levels nor the TNF-alpha or IL-1beta induction of pJNK or pERK were affected by culturing RA synovial fibroblasts with 3 muM lovastatin."

reach
"Similarly, the protein levels of p-JNK, JNK, p-ERK1/2, and ERK1/2 were relatively stable in hNPCs treated with TNF-alpha for different durations."

reach
"Also, TNF-alpha treatment increased p-p38 and p-ERK, and pretreatment of NMA reduced this increased expression of p-p38 and p-ERK."

reach
"Artemisinin significantly inhibited the protein level of phosphorylated ERK1/2 and p38 MAPK induced by TNF-alpha in the HUVECs at all concentrations tested, while the inhibition of the phosphorylation of JNK was only observed at the high concentrations (100 and 200 microM) (XREF_FIG)."

reach
"Besides, we demonstrated that TNF-alpha treatment induced a time dependent increase of p-ERK, peaking at 5min and then decreasing to a steady level that remained higher than in unstimulated cells up to 120min, as revealed by MFI and by western blot analyses."

reach
"The results clearly show that phospho-ERK is enhanced after acute BDNF treatment for 10 min and is further increased by 48 hours of TNF-α pre-treatment (Figure 9B, 9E)."

reach
"TNFalpha stimulation significantly increased phospho-ERK in IB3-1 at 30 min (p = 0.04)."

reach
"Prevention of TNFalpha induced pERK and NF-kappaB signaling abrogates the TNFalpha induced decrease in aquaporin 3 mRNA expression."

reach
"Mechanistically, MADD siRNA inhibited TNFalpha induced activation of pERK, pGSK3beta and beta-catenin, suggesting that MADD knockdown might exert its anti-migratory and invasive effects, by blocking TNFalpha/ERK/GSK3beta axis."

reach
"Icariin treatment resulted in a reduced expression of p-P38 and p-ERK signal activation induced by TNF-alpha and IFN-gamma; however, only SB203580, the p38 alpha/beta inhibitor, inhibited the secretion of inflammatory cytokines induced by TNF-alpha and IFN-gamma in cultured HaCaT cells."

reach
"Topical application of TNF-alpha to rat nerve root increased pERK in ipsilateral dorsal root ganglion (DRG) neurons and glia within 5 hours."

reach
"Instead of inhibiting C3a or TNF induced p-ERK1/2, pre-treatment with manumycin A directly resulted in a robust increase in p-ERK1/2."

reach
"To determine whether the different patterns of pERK required newly synthesized proteins, cells were treated with cycloheximide and TNFalpha."

reach
"AP-activated TNF-α induces ALI via p-JNK/MAPK and p-ERK/MAPK in the lung, while p38MAPK can be activated by a variety of extracellular stimuli, such as inflammatory mediators, heat injury, and ultraviolet light."

reach
"In MDA-MB-231 cells, level of p-p38 expression was up-regulated, while no significant change of p-JNK and p-ERK expression when cells were treated with same amount of TNF-alpha."

reach
"DLD-1, DKs8, and DKs8-kdN had elevated pERK signals when treated with cycloheximide and TNFalpha, compared to TNFalpha alone (XREF_FIG)."

reach
"TNF-alpha induced a significant enhancement of p-ERK1/2, and an upregulation of mRNA and protein of Egr-1."
