Mice deficient for p66shcA represent an animal model to link oxidative stress and aging. p66shcA is implicated in oxidative stress response and mitogenic signaling. Phosphorylation of p66shcA on Ser36 is critical for its function in oxidative stress response. Here we report the identification of ERK as the kinase phosphorylating p66shcA on Ser36. Activation of ERKs was necessary and sufficient ...
BACKGROUND Trichloroacetic acid, an oxidative metabolite of trichloroethylene (TRI), is a ligand of the peroxisome proliferator-activated receptor alpha (PPAR) alpha, which is involved in lipid homeostasis and anti-inflammation. OBJECTIVE We examined the role of mouse and human PPARalpha in TRI-induced hepatic steatosis and toxicity. METHODS Male wild-type (mPPARalpha), Pparalpha-null, and ...
In this experimental work, the effect of vitamin and mineral concentrate P52-1 domestic production as part barley wheat compound feeds on growth dynamics young pigs their health indicators for experiment duration was studied. At same time, physiological parameters studied animals were considered. Morphobiochemical studies blood allowed to conclude that feed additive had a positive metabolism in...
Postmenopausal osteoporosis and rheumatoid joint destruction result from increased osteoclast formation and bone resorption induced by receptor activator of NF-kappaB ligand (RANKL) and tumor necrosis factor (TNF). Osteoclast formation induced by these cytokines requires NF-kappaB p50 and p52, c-Fos, and NFATc1 expression in osteoclast precursors. c-Fos induces NFATc1, but the relationship betw...
To elucidate the mechanisms responsible for cytoprotective effects of TNF receptor-activated factor 2 (TRAF2) in the heart, we employed genetic gain- and loss-of-function studies ex vivo and in vivo in mice with cardiac-restricted overexpression of TRAF2 (Myh6-TRAF2LC). Crossing Myh6-TRAF2LC mice with mice lacking canonical signaling (Myh6-TRAF2LC/Myh6-IκBαΔN) abrogated the cytoprotective effec...
NF-κB is an inducible transcription factor that mediates signal transduction between the cytoplasm and nucleus in many cell types [1] and controls the expression of numerous genes involved in cell growth, differentiation, regulation of apoptosis, cytokine production, and neoplastic transformation [2]. It is a member of the Rel family, which includes NF-κB1 (p50), NF-κB2 (p52), RelA (p65), RelB,...
Peripheral T-cell lymphomas (PTCLs) are generally aggressive non-Hodgkin lymphomas with poor overall survival rates following standard therapy. One-third of PTCLs express interferon regulatory factor-4 (IRF4), a tightly regulated transcription factor involved in lymphocyte growth and differentiation. IRF4 drives tumor growth in several lymphoid malignancies and has been proposed as a candidate ...
