Betulinic acid reduces ultraviolet-C-induced DNA breakage in congenital melanocytic naeval cells: Evidence for a potential role as a chemopreventive agent
(2001)Melanoma transformation progresses in a multistep fashion from precursor lesions such as congenital naevi. Exposure to ultraviolet (UV) light promotes this process. Betulinic acid (BA) was identified by our group as a ...

Induction of caspase-independent programmed cell death by vitamin E natural homologs and synthetic derivatives.
(2009)Current observations in the literature suggest that vitamin E may be a suitable candidate for cancer chemotherapy. To investigate this further, we examined the ability of the vitamin E natural homologs [alpha-, beta-, ...

Resistance to etoposide in human leukemia HL-60 cells: Reduction in drug-induced DNA cleavage associated with hypophosphorylation of topoisomerase II phosphopeptides
(1996)Tumor cell resistance to anthracyclines and epipodophyllotoxins can be due to reduced drug accumulation and/or alterations in the activity of topoisomerase II (TOPO II). HL-60 cells selected in 0.05 μg/ml doxorubicin (DOX) ...

Rotenoids mediate potent cancer chemopreventive activity through transcriptional regulation of ornithine decarboxylasetissue plasminogen activator-mediated thrombolysis
(1995)For the discovery of new cancer chemopreventive agents, we have studied the potential of plant extracts to inhibit phorbol ester-induced ornithine decarboxylase (ODC) activity in cell culture. Four active rotenoids were ...

Therapeutic monitoring of continuous infusion etoposide in small-cell lung cancer
(1996)Purpose: To investigate the feasibility of therapeutic monitoring of etoposide at different plasma concentrations of the drug, and the resulting pharmacodynamic effects of such an approach. Patients and Methods: Forty- ...
