Examination of syngeneic tumor regressor sera prepared by immunization of mice with several different lymphomas revealed a common pattern of reactivity to proteins expressed in these tumors. Antibodies present in these sera immunoprecipitate a triplet of proteins of 115,000 mol wt (p115), 80,000 mol wt (p80), and 32,000 mol wt (p32) from many but not all T cell lymphomas of mice. P80, the predo...

New treatment strategies are required for the debilitating inflammatory bowel diseases (IBD), Crohn's Disease and Ulcerative Colitis. DP inhibitors can prolong the bioactivity of the potent intestinotrophic growth factor glucagon-like peptide-2 (GLP-2(1-33)). We investigated whether novel inhibitors of DP activity could modify the course of disease activity in the dextran sulfate sodium (DSS) m...

Mammalian mitochondrial DNA (mtDNA) exists in structures called nucleoids, which correspond to the configuration of nuclear DNA. Mitochondrial transcription factor A (TFAM), first cloned as an mtDNA transcription factor, is critical for packaging and maintaining mtDNA. To investigate functional aspects of TFAM, we identified many RNA-binding proteins as candidate TFAM interactors, including ERA...

Previous studies showed that acetylcholine, in the presence of cserine, stimulated the incorporation of P3* into the phospholipidcs in slices of guinea pig brain cortex (2, 3). The major stimulation occurred in phosphoinositidc and in phosphatidic acid, with a lesser stimulation in phosphatidyl choline (3). The incorporation of glycerol-l-U4 into the total glycerophosphatide fraction was not in...

I T IS A distinct pleasure to dedicate the first published* of a series of articles from this laboratory on the use of radio isotopes in human physiologic studies to Dr. George R. Minot. It was under his direction that our venture into this field was undertaken. Radio phosphorus has been used in the examination of various phases of phosphorus metabolism and the results have been summarized by H...
