p38 MAP kinases (p38) and c-Jun N-terminal protein kinases (JNK) have been associated with TNF-α-induced apoptosis. However, recent studies indicate that an early but brief activation of JNK and/or p38 may actually protect some cells from TNF-α-ind

We reported previously that Ro-318220 blocked expression of mitogen-activated protein kinase phosphatase-1 (MKP-1) induced by tumor necrosis factor-α (TNF-α) and subsequently caused apopotosis in mesangial cells (Y.-L. Guo, B. Kang, and J. R. Willi

Previously we showed that rat mesangial cells are normally resistant to tumor necrosis factor-alpha (TNF-alpha)-induced apoptosis. They are made susceptible to the apoptotic effect of TNF-alpha when pretreated with actinomycin D, cycloheximide or van

The protein kinase C (PKC) family represents an important group of enzymes whose activation is associated with their translocation from the cytosol to different cellular membranes. In this study, the spatial distribution of PKC-alpha, -delta and -eps

Angiotensin II stimulates a biphasic activation of Raf-1, MEK, and ERK in WB liver epithelial cells. The first peak of activity is rapid and transient and is followed by a sustained phase. Angiotensin II also causes a rapid activation of p21ras in th

Association of phospholipase C (PLC)-gamma 1 with the cytoskeleton has been postulated to be one of the crucial steps for PLC-gamma 1 activation and translocation to the plasma membrane. In this report, direct binding assays were carried out to study

In this study, we have examined the relationship between epidermal growth factor (EGF)-induced tyrosine phosphorylation of phospholipase C-gamma 1 (PLC-gamma 1) and its translocation from the cytosol to the Triton X-100-insoluble cytoskeleton fractio

Fuel- and receptor-induced signal transduction pathways were investigated in beta-TC3 cells, an insulin-secreting cell line. An increase of glucose concentration from 0 to 15 mM and stimulation with 0.5 mM carbachol resulted in up to a twofold increa

The regulation of intracellular pools of Ca2+ was investigated in an interleukin-3 (IL-3)-dependent hematopoietic cell line 32D that undergoes programmed cell death ("apoptosis") when deprived of lymphokine. Comparisons were made with 32D cells that
