Phosphatidylinositol 3-Monophosphate Is Involved in Toxoplasma Apicoplast Biogenesis
Apicomplexan parasites cause devastating diseases including malaria and toxoplasmosis. They harbour a plastid-like, non-photosynthetic organelle of algal origin, the apicoplast, which fulfils critical functions for parasite survival. Because of its essential and original metabolic pathways, the apicoplast has become a target for the development of new anti-apicomplexan drugs. Here we show that ...
متن کاملInduction of apoptosis by novel inosine monophosphate dehydrogenase, 3-hydrogenkwadaphnin
Today’s medical word is highly dependent on severel natural products (e.g. taxol) in fighting different kinds of cancer and in constantly working to found new compounds. In this respect, 3-hydrogenkwadaphnin is a new diterpene ester isolated from Dendrostellera lessertii (Thymelaceae). It has been previously shown that this new compound has high anti-tumor activity and the capability of arresti...

متن کاملNeomycin inhibits the phosphatidylinositol monophosphate and phosphatidylinositol bisphosphate stimulation of plasma membrane ATPase activity.
The inositol phospholipids, phosphatidylinositol monophosphate (PIP) and phosphatidylinositol bisphosphate (PIP(2)), have been shown to increase the vanadate-sensitive ATPase activity of plant plasma membranes (AR Memon, Q Chen, WF Boss [1989] Biochem Biophys Res Commun 162: 1295-1301). In this paper, we show the effect of various concentrations of phosphatidyinositol, PIP, and PIP(2) on the pl...
متن کاملThe activation of protein kinase C by the polyphosphoinositides phosphatidylinositol 4,5-diphosphate and phosphatidylinositol 4-monophosphate.
Protein kinase C(PKC) is a Ca2+- and phospholipid-dependent protein kinase which can be activated by diacylglycerol, a product of polyphosphoinositide hydrolysis. In this report, we show that the polyphosphoinositides L-alpha-phosphatidylinositol 4-monophosphate (PI 4P) and L-alpha-phosphatidylinositol 4,5-diphosphate (PI 4.5DP) can serve as phospholipid cofactors of isolated rat brain PKC. The...
