p90 ribosomal S6 kinase 3 contributes to cardiac insufficiency in α-tropomyosin Glu180Gly transgenic mice.
Myocardial interstitial fibrosis is an important contributor to the development of heart failure. Type 3 p90 ribosomal S6 kinase (RSK3) was recently shown to be required for concentric myocyte hypertrophy under in vivo pathological conditions. However, the role of RSK family members in myocardial fibrosis remains uninvestigated. Transgenic expression of α-tropomyosin containing a Glu180Gly muta...
متن کاملEffects of nicotine administration in a mouse model of familial hypertrophic cardiomyopathy, α-tropomyosin D175N.
The effects of nicotine (NIC) on normal hearts are fairly well established, yet its effects on hearts displaying familial hypertrophic cardiomyopathy have not been tested. We studied both the acute and chronic effects of NIC on a transgenic (TG) mouse model of FHC caused by a mutation in α-tropomyosin (Tm; i.e., α-Tm D175N TG, or Tm175). For acute effects, intravenously injected NIC increased h...
متن کاملEvaluation of Novel α-(Acyloxy)-α-(Quinolin-4-yl) Acetamides as Antiplasmodial Agents
Because of expanding resistance to efficient and affordable antimalarial drugs likechloroquine, the search is continuing for more effective drugs against this disease. In-vitroantiplasmodial activity and cytotoxicity of α-(acyloxy)-α-(quinolin-4-yl) acetamides onPlasmodium falciparum and structure-activity relationships of this new class of Passeriniadducts is described. The in-vitro antiplasmo...

متن کاملDynamic structural flexibility of α-synuclein
α-Synuclein is a conserved, abundantly expressed protein that is partially localized in pre-synaptic terminals in the central nervous system. The precise biological function(s) and structure of α-synuclein are under investigation. Recently, the native conformation and the presence of naturally occurring multimeric assemblies have come under debate. These are important deliberations because α-sy...
