    摘要: The invention relates to methods for identifying compounds which affect cellular stress. In particular, the method relates to identifying compounds which inhibit protein advanced glycation end product formation, where the compounds are carbonyl scavengers which inhibit the formation. The assay involves combing the substance of interest with histone H1 and ADP-ribose, and then measuring fluorescence and protein cross linking. Various inhibitors of protein AGE glycation have been identified, using this assay.

    摘要: Carbonyl scavengers, which have been recognized for their ability to react with reactive carbonyl species, have been implicated as agents that can accelerate or induce the death of abnormal cells without having a parallel effect on normal cells. As such, they are useful therapeutic agents in cases where the acceleration or induction of cell death is desirable, such as in cells where the normal apoptotic pathways have been disrupted and where hyperproliferative cell growth occurs.

    摘要: The isolation and characterization of cDNAs encoding poly(ADP-ribose) glycohydrolase (PARG) enzymes and the amino acid sequences of PARGs from several species are described. PARG is involved in the cellular response to DNA damage and its proper function is associated with the body's response to neoplastic disorder inducing agents and oxidative stress. Expression vectors containing the cDNAs and cells transformed with the vectors are described. Probes and primers that hybridize with the cDNAs are described. Expression of the cDNA in E. coli results in an enzymatically active protein of about 111 kDa and an active fragment of about 59 kDa. Methods for inhibiting PARG expression or overexpressing PARG in a subject for therapeutic benefit are described. Exemplary of PARG inhibitors are anti-sense oligonucleotides. The invention has implications for treatment of neoplastic disorder, heart attack, stroke, and neurodegenerative diseases. Methods for detecting a mutant PARG allele are also described. Antibodies immunoreactive with PARGs and fragments thereof are described.

    摘要: The invention relates to assay or determining intercellular niacin status in solid tissues. One extracts intracellular pyredine nucleotides, cycles these, in the presence of agents which reduce the pyredine nucleotides and a dye, which reflect the change. Changes in absorbance of the dye molecule permit determination of the niacin status.
