The synthesis of melatonin in Xenopus retinas, chick and quail retinal cell cultures, and Y79 human retinoblastoma cells is stimulated by cAMP through a protein synthesis-dependent mechanism. In Y79 retinoblastoma cells, combined treatment with the RNA synthesis inhibitor camptothecin and agents that elevate cAMP, such as forskolin, causes a synergistic elevation of melatonin. Using two-dimensi...
widespread studies on tumor diagnosis has led to the development of techniques with greater sensitivity and improved specificity for detection of occult and small subclinical tumors. tumor imaging by radiolabeling of tumor-specific antibodies (immunoscintigraphy) or tissue specific biochemical agents (receptor imaging) and especially physiologic imaging with positron emitters (pet), have opened...
This unit describes metabolic labeling techniques that provide specific information about the structure, sequence, and distribution of the sugar chains of glycoconjugates. Although these techniques provide less information than complete sequencing of the sugar chains, the partial structural information derived is sufficient for many purposes. In the basic procedure presented in this unit, activ...
INTRODUCTION Human antimicrobial peptides are of interest for the development of positron emission tomography (PET) tracers as they exhibit desirable characteristics that make them good candidates for targeting vectors. Due to their natural role in the innate immune system they selectively bind to pathogenic bacteria and yeast, whilst remaining minimally immunogenic and cytotoxic to humans. Res...
Background: For understanding the roles of fatty acids on the induction of acrosome reaction which occurs under association of cholesterol efflux and PKA or PKC pathways in boar spermatozoa, metabolic fate of alone and combined radiolabeled 14C-oleic acid and 3H-linoleic acid incorporated in the sperm was compared, and behavior of cholesterol and effects of PKA and PKC inhibitors upon fatty aci...
