Growth and Differentiation of a Human T-Cell Leukemia Cell Line, CCRF-CEM, Grafted in Mice1
The growth of human CCRF-CEM T-cell lymphoblastic leukemia was studied in mice immune deprived by different techniques, and in CD-nu/ nu atli>mie mice. Female CBA/CaJ mice were immune deprived by infant thymectomy, priming with l-/î-i>-arabinofuranosylcytosine(200 mg/kg) 48 h prior to total body irradiation (925 cGy) designated Oara-Cy; or after thymectomy the mice received 925 cGy total body ...
متن کاملGrowth and differentiation of a human T-cell leukemia cell line, CCRF-CEM, grafted in mice.
The growth of human CCRF-CEM T-cell lymphoblastic leukemia was studied in mice immune deprived by different techniques, and in CD-nu/nu athymic mice. Female CBA/CaJ mice were immune deprived by infant thymectomy, priming with 1-beta-D-arabinofuranosylcytosine (200 mg/kg) 48 h prior to total body irradiation (925 cGy) designated theta ara-C gamma; or after thymectomy the mice received 925 cGy to...
متن کاملMultifactorial resistance to 5,10-dideazatetrahydrofolic acid in cell lines derived from human lymphoblastic leukemia CCRF-CEM.
5,10-dideaza-5,6,7,8-terrahydrofolic acid (DDATHF) is a potent antiproliferative agent in cell culture systems and in vivo in a number of murine and human xenograft tumors. In contrast to classical antifolates, which are dihydrofolate reductase inhibitors, DDATHF primarily inhibits GAR transformylase, the first folate-dependent enzyme along the pathway of de novo purine biosynthesis. The (6R) d...
متن کاملCytotoxicity of 91 Kenyan indigenous medicinal plants towards human CCRF-CEM leukemia cells.
ETHNOPHARMACOLOGICAL RELEVANCE Plants from Kenyan flora are traditionally used against many ailments, including cancer and related diseases. Cancer is characterized as a condition with complex signs and symptoms. Recently there are recommendations that ethnopharmacological usages such as immune and skin disorders, inflammatory, infectious, parasitic and viral diseases should be taken into accou...
متن کامل(6R)-5,10-Dideaza-5,6,7,8-tetrahydrofolic acid effects on nucleotide metabolism in CCRF-CEM human T-lymphoblast leukemia cells.
(6R)-5,10-Dideaza-5,6,7,8-tetrahydrofolic acid [(6R)DDATHF] is a folate antimetabolite with activity specifically directed against de novo purine synthesis, primarily through inhibition of glycinamide ribonucleotide transformylase. This inhibition resulted in major changes in the size of the nucleotide pools in CCRF-CEM cells. After a 4-h incubation with 1 microM (6R)DDATHF, dramatic reductions...
