Descrizione generale
A cell permeable, highly specific inhibitor of protein kinase C (IC50 = 50 nM) that interacts with the protein’s regulatory domain by competing at the binding site of diacylglycerol and phorbol esters. Does not compete with Ca2+ or phospholipids. At higher concentrations inhibits myosin light chain kinase (IC50 >5 µM), protein kinase A (IC50 >50 µM), protein kinase G (IC50 >25 µM), and p60v-src (IC50 >50 µM). Induces apoptotic DNA fragmentation and cell death in HL-60 human promyelocytic leukemia cells. Requires brief exposure to light for activation.
Cell-permeable, highly specific inhibitor of protein kinase C (IC50 = 50 nM) that interacts with the protein′s regulatory domain by competing at the binding site of diacylglycerol and phorbol esters. At higher concentrations inhibits myosin light chain kinase (IC50 >5 µM), protein kinase A (IC50 >50 µM), protein kinase G (IC50 >25 µM), and p60v-src protein tyrosine kinase (IC50 >50 µM). Does not compete with Ca2+ or phospholipids. Also induces apoptotic DNA fragmentation and cell death in HL-60 human promyelocytic leukemia cells. Inhibition of PKC is dependent on exposure to light in cell-free systems. Ordinary fluorescent light is sufficient for full activation.

Aggregation by immune complexes of receptors specific for the Fc region of IgG results in their internalisation and disposal by trafficking to lysosomes. We show here that internalisation of FcgammaRI by IFN-gamma treated U937 cells following receptor aggregation by cross-linking

Chronic malnutrition (M) affects >1 billion people worldwide. Epidemiological data point to long-term renal and cardiovascular outcomes (e.g. arterial hypertension, cardiorenal syndromes). The renin-angiotensin-aldosterone system (RAAS) has been implicated in the physiopathology of these disturbances, but M-induced alterations in RAAS-modulated
