[Methyl-14C]-choline incorporation into nude mice bearing tumor xenografts-correlation with [methyl-3H]-thymidine: A pilot study
Background: Many in vitro studies suggested that choline incorporation into many types of tumors is related to cell proliferation. Whether in vivo choline incorporation is related also to cell proliferation or not was my question. Therefore, the aim of this pilot study was to investigate the relationship of in vivo [methyl- 14C]-choline incorporation and in vivo [methyl-3H]- thymidine incorpora...
متن کامل(n,1,1,α)-Center Problem
Given a set of points in the plane and a constant ,-center problem is to find two closed disks which each covers the whole , the diameter of the bigger one is minimized, and the distance of the two centers is at least . Constrained -center problem is the -center problem in which the centers are forced to lie on a given line . In this paper, we first introduce -center problem and its constrain...
متن کاملThe synthesis of high-specific-activity UDP-[6-3H]galactose, UDP-N-[6-3H]acetylgalactosamine, and their corresponding monosaccharides.
Tritiated uridine-5'-diphosphogalactose (UDP-[3H]Gal) has been widely used to study oligosaccharide biosynthesis and structure. It can be synthesized either chemically or enzymatically using galactose oxidase to oxidize the hydroxyl moiety at C-6 to an aldehyde (6-aldo-UDP-Gal), which is then reduced back to the alcohol with tritiated sodium borohydride. Although the enzymatic approach is simpl...
متن کاملMalnutrition: Incorporation of Thymidine-3h into Nuclear and Mitochondrial Dna
Protein-calorie malnutrition or fasting leads to a readily detectable decrease in the rate of body growth and cellular proliferation, particularly in young animals (32, 33) . In contrast, disorders in cell and organ function have generally been more difficult to demonstrate, perhaps partly due to limitations in methodology (8, 16, 22) . Mitochondria are the primary energy source for the work of...
متن کاملInhibition of [3H]thymidine incorporation into DNA of rat esophageal epithelium and related tissues by carcinogenic N-nitroso compounds.
We studied effects on [3H]thymidine incorporation into the DNA of rat esophageal epithelium measured 1 hr after the thymidine injection and expressed as cpm/^g DNA. When various doses of 8 N-nitroso compounds were injected into rats 4 hr before they were killed, the highest doses inhibited the incorporation by 65 to 82%. The dose causing 50% inhibition was 2.3 mg/kg for methyl-n-amylnitrosamine...
