malic enzyme/白血病

Two lymphoid cell lines were established from a patient with chronic lymphocytic leukemia by infecting blood cells with Epstein-Barr virus (EBV). Studies of morphology, glucose-6-phosphate dehydrogenase, malic enzyme, immunoglobulin, and chromosomes of the two lines indicated that one of them

Soluble malic enzyme (MEs) has been examined in long-term human lymphoid cell lines cultured from 101 individuals. In 65 out of 66 lines derived from people without lymphoreticular malignancy the enzyme was very active. Lines established from 35 individuals with various forms of lymphoreticular

Malic enzyme 2 (ME2) is a mitochondrial enzyme that catalyzes the conversion of malate to pyruvate and CO2 and uses NAD as a cofactor. Higher expression of this enzyme correlates with the degree of cell de-differentiation. We found that ME2 is expressed in K562 erythroleukemia cells, in which a

Adriamycin is used for the treatment of leukemia and other neoplastic processes. Unfortunately the drug has a toxic effect on some tissues. Cardiotoxicity in particular limits the use of the drug. Several hypotheses have been given to explain adriamycin heart toxicity. The authors have studied the

To determine the capacity of the chicken c-erbA (cTR-alpha) gene product in regulating expression of known thyroid hormone-responsive genes, both the cTR-alpha and the viral v-erbA genes were expressed in FAO cells, a rat hepatoma cell line defective for functional thyroid hormone receptors. Upon

There are three known isoforms of the rat thyroid hormone receptor, TR alpha-1, TR beta-1, and TR beta-2. The first two are expressed in all tissues, whereas TR beta-2 appears to be expressed only in the pituitary. The differences in the roles of the three receptor isoforms are unknown, but may
