In order to investigate the contribution of polyamines and related amino acids in the maintenance of zucchini fruit quality during cold storage, two varieties of Cucurbita pepo with different degrees of chilling tolerance were used, Natura (more tole

A replication study with some extensions was made to confirm enhancement of ornithine decarboxylase (ODC) activity in murine L929 fibroblasts after radiofrequency (RF) field exposure reported in earlier studies. L929 cells purchased from two cell ban

Ornithine decarboxylase (ODC) is the first and the rate-limiting enzyme in polyamine biosynthesis. Polyamines play key roles in cell proliferation, renal membrane transportation, and plasma membrane calcium fluxes. As part of a multidisciplinary rese

We studied the influence of magnetic fields (MFs) and simulated solar radiation (SSR) on ornithine decarboxylase (ODC) and polyamines in mouse epidermis. Chronic exposure to combined MF and SSR did not cause persistent effects on ODC activity or poly

In previous work, we examined factors which influence magnetic-field induced enhancement of ornithine decarboxylase (ODC) activity in L929 fibroblasts. Results from that work indicated that enhancement of ODC activity by a 60-Hz magnetic field is inf

The effects of ethyl alcohol (EtOH) during or after treatment with N-nitrosomorpholine (NNM) on hepatocarcinogenesis, ornithine decarboxylase (ODC) activity and the labeling index of the liver were investigated in male Sprague-Dawley rats. Rats were

The present study was undertaken to see if ODC activity in cell lines with similar origin (lymphoblastic leukemia) respond in a similar fashion to a 0.10 mT magnetic field, and also if ‘down-stream’ effects, i.e. synthesis of polyamines, are infl

In this study we have examined the relationship between growth factor-induced proliferation and ODC/polyamine levels. TGFβ promotes cell growth and enhances [3H]-thymidine incorporation in chick embryo fibroblasts maintained in a serum-depleted medi

S-Adenosyl-L-methionine (SAM) is a strong chemo-preventive agent of rat liver carcinogenesis. Examination was made to determine whether inhibition by SAM of the development of preneoplastic liver lesions persists to SAM withdrawal in diethylnitrosami
