The effect of 15dPGJ(2) on PKC zeta activity observed in LPS-activated macrophages was not dependent on a direct action of this prostaglandin on the enzyme but was due to the activation of a step upstream of PI3-kinase. Moreover, LPS promoted the redistribution of a …

H-Ras-specific activation of NF-kappaB protects NIH 3T3 cells against stimulus-dependent apoptosis.
Millán O, Ballester A, Castrillo A, Oliva JL, Través PG, Rojas JM, Boscá L. Millán O, et al. Oncogene. 2003 Jan 30;22(4):477-83. doi: 10.1038/sj.onc.1206179. Oncogene. 2003. PMID: 12555061
Cells expressing H-Ras exhibited a basal kappaB activity that correlated with sustained IkappaB kinase activation and lower steady-state levels of IkappaBalpha in the cytosol. Upon activation with TNFalpha, the cells expressing the distinct Ras isoforms behaved similarly i …

The increase in TNF-alpha levels is implicated in NF-kappaB activation and inducible nitric oxide synthase expression in brain cortex after immobilization stress.
Madrigal JL, Hurtado O, Moro MA, Lizasoain I, Lorenzo P, Castrillo A, Boscá L, Leza JC. Madrigal JL, et al. Neuropsychopharmacology. 2002 Feb;26(2):155-63. doi: 10.1016/S0893-133X(01)00292-5. Neuropsychopharmacology. 2002. PMID: 11790511
Now we have found that a short duration of stress (immobilization for 6 h) also induces the expression of iNOS in brain cortex in adult male rats. ...In order to study the role of TACE and TNF-alpha in iNOS induction, a group of animals were i.p. injected with the p …
