Current strategies for repairing the adult CNS following injury include cell transplantation and/or the use of viral vectors to deliver therapeutic agents. Although promising, both techniques are limited in their usefulness due to the immunological response triggered in the brain as a result of the introduction of foreign antigens. An alternative method to(More)
Serum neuron-specific enolase (NSE) was measured in 61 children at diagnosis with all stages of neuroblastoma. The median serum values for Stages I, II, III, IV, and IV-S were 13, 23, 40, 214, and 40 ng/ml, respectively. Mean serum levels were different between groups I versus IV, (P = 0.0004) II versus IV (P = 0.0001) and IV-S versus IV (P = 0.004). The(More)
The antiestrogenic potency of benz[a]anthracene-3,9-diol, as well as its 7- and 12-methyl derivatives, was evaluated by measuring he inhibition in the onset of estrus brought about by this compound in ovariectomized rats treated with 17beta-estradiol. At a dose of 0.5 mg and 7,12-dimethyl derivative caused a decrease in the percentage of rats in estrus from(More)
An adriamycin-resistant human breast tumor cell line MDA-A1R was generated by step-wise selection in increasing concentrations of drug from the parent cell line MDA-MB-231. MDA-A1R cells grow as loosely attached cell aggregates with a doubling time of 28-32 h; the MDA-MB-231 parent cell line grows as a standard monolayer culture with a 20-h doubling time.(More)
Biopsy specimens of 55 human mammary carcinomas (38 primary and 17 metastatic) were assayed for prolactin receptors (PrlR). Prolactin bound specifically to 32 (58%) of the tumor biopsy specimens. The apparent Kd for PrlR in individual tumors ranged from 15 pM to 2.3 nM (mean 600 pM, n = 5) and the concentration of PrlR ranged from 0 to 44.5 fmoles/mg(More)
Multidrug resistance in Chinese hamster ovary cells is associated with the Mr 170,000 surface glycoprotein. Using our monoclonal antibody to this protein, we have isolated a complementary DNA clone from an expression vector library. This complementary DNA recognizes a 4.5-kilobase mRNA in drug-resistant but not-sensitive Chinese hamster ovary cells; it also(More)
A review of the role of steroid hormone receptors and hormonal dependence of renal cell carcinoma in certain patients is presented. The results of a cumulative series of estrogen, progesterone, and androgen receptor assays performed on 48 normal and malignant human renal tumor specimens are given. The detectable presence of receptor proteins in certain(More)
After incubation with [3H]estradiol low-salt sucrose gradient centrifugation of 250 human breast tumor cytosis demonstrated receptor-bound steroid in both 4 S and 8 S forms. Cytosols prepared from 24 of these receptor-positive tumors were examined in the presence of KCl, Ca2+ and the serine protease inhibitor, phenylmethylsulfonyl fluoride. After incubation(More)
The estrogen receptor binding properties of 3,9-dihydroxybenz[a]anthracene (3,9-diOHBA) were determined in uterine cytosol of immature Sprague-Dawley rats by competitive binding experiments with [3H]estradiol and sucrose density centrifugation. 3,9-DiOHBA inhibited estradiol binding to the 8S binding protein at a concentration (1.2 X 10(-5) M) approximately(More)
