- In Vivo Inhibition of Beta-Secretase Several animal models, including mouse, rat, dog, and monkey, may be used to screen for inhibition of beta-secretase activity in vivo following administration of a test compound sample. Animals used in this invention can be wild type, transgenic, or gene knockout animals. For example, the Tg2576 mouse model, prepared and conducted as described in Hsiao et al., 1996, Science 274, 99-102, and other non-transgenic or gene knockout animals are useful to analyze in vivo inhibition of Amyloid beta peptide (Abeta) production in the presence of inhibitory test compounds. Generally, 2 to 18 month old Tg2576 mice, gene knockout mice or non-transgenic animals are administered test compounds formulated in vehicles, such as cyclodextran, phosphate buffers, hydroxypropyl methylcellulose or other suitable vehicles. One to twenty-four hours following the administration of compound, animals are sacrificed, and brains as well as cerebrospinal fluid (CSF) and plasma are removed for analysis of A-beta levels and drug or test compound concentrations (Dovey et al., 2001, Journal of Neurochemistry, 76, 173-181) Beginning at time 0, animals are administered by oral gavage, or other means of delivery such as intravenous injection, an inhibitory test compound of up to 100 mg/kg in a standard, conventional formulation, such as 2% hydroxypropyl methylcellulose, 1% Tween80. A separate group of animals receive 2% hydroxypropyl methylcellulose, 1% Tween80 alone, containing no test compound, and serve as a vehicle-control group. At the end of the test period, animals are sacrificed and brain tissues, plasma or cerebrospinal fluid are collected. Brains are either homogenized in 10 volumes (w/v) of 0.2% diethylamine (DEA) in 50 mM NaCl (Best et al., 2005, Journal of Pharmacology and Experimental Therapeutics, 313, 902-908), or in 10 volumes of 0.5% TritonX-100 in Tris-buffered saline (pH at about 7.6). Homogenates are centrifuged at 355,000 g, 4° C. for 30 minutes. CSF or brain supernatants are then analyzed for the presence of A-beta peptide by specific sandwich ELISA assays based on ECL (Electrochemiluminescence) technology.

Wahl, Salk Institute for Biological Studies, San Diego, CA A wild type but attenuated p53 is retained in approximately 50% of human tumors, and reactivation of p53 in such tumors is an attractive chemotherapeutic strategy. p53 activity is restricted in vivo by mdm2 and mdmx, and knockout of either of these proteins is embryonic lethal in a p53-dependent manner (1, 2). Both proteins bind to p53 via a hydrophobic N-terminal pocket and block p53-dependent transcription of genes required for tumor suppression. Efforts to reactivate p53 with small molecules have focused on inhibition of the mdm2/p53 interaction, which leads to increased p53 levels and activity. However, recent reports indicate that targetin

Description: The trypanosomatid parasites T. brucei ssp., T. cruzi and Leishmania spp. are the causative agents of human African trypanosomiasis (HAT), Chagas' disease, and leishmaniasis, and economically important diseases in livestock. All trypanosomatids require a unique form of RNA editing for mitochondrial gene expression, and through conditional knockout studies in T. brucei in culture and in mice we ha

- TDP2 Assays with Whole Cell Extracts Ten-million cells (1 x 107), either human, chicken DT40 wild type, or knockout for TDP2 and complemented with human TDP2, were collected, washed, and centrifuged. Cell pellets were then resuspended in 100 uL of CelLytic M cell lysis reagent (SIGMA-Aldrich C2978). After 15 min on ice, lysates were centrifuged at 12 000g for 10 min, and supernatants were transferred to a new tube. Protein concentrations were determined using a Nanodrop spectrophotometer (Invitrogen), and whole cell extracts were stored at -80 °C. The TY19 single-stranded DNA oligonucleotide containing a 5'-phosphotyrosine (see above) was incubated at 1 nM with 10-20 ug/mL of whole cell extract to obtain 30-40% cleavage in the absence or presence of inhibitor for 15 min at RT in the reaction buffer containing 50 mM Tris-HCl, pH 7.5, 80 mM KCl, 5 mM MgCl2, 0.1 mM EDTA, 1 mM DTT, 40 ug/mL BSA, and 0.01% Tween 20. Reactions were terminated and samples analyzed.
