Preclinical results indicate acidic fibroblast growth factor (aFGF) and basic FGF (bFGF) present in solid tumors as a cause of broad-spectrum chemoresistance, whereas earlier clinical studies suggest that bFGF expression is associated with opposing o

Purpose: The present study evaluated the tissue distribution and targeting advantage of intraprostatic chemotherapy. Experimental Design: We studied the delivery and spatial distribution of a fluorescent drug, doxorubicin, in the prostate of beagle d

Purpose. We recently demonstrated simultaneous targeting of telomere and telomerase as a novel cancer therapeutic approach, and that telomerase inhibitors such as 3′azido-3′deoxythymidine (AZT) significantly enhanced the antitumor activity of pac

We reported that suramin is an effective chemosensitizer at noncytotoxic concentrations (60 μM for cytotoxicity), and continuous treatment at 10–25 μM for 6 weeks resulted in gradual telomere shortening (maximum of 30%) and cell senescence (measu

Purpose. Telomeres are specific DNA structure at the ends of chromosomes to protect chromosomes from fusion, recombination, and degradation. Telomere length changes are implicated in cell senescence, aging, tumorigenesis, and DNA repair. The standard

Purpose. Telomerase is a ribonucleoprotein that extends telomeres at the ends of chromosome. Increased telomerase activity is associated with cellular immortality. The currently available assay for telomerase, i.e., telomeric repeat amplification pro

We have previously reported incomplete cytotoxic responses of other human solid tumors (bladder, head and neck, ovarian and prostate) to paclitaxel. This finding is qualitatively different from the nearly complete response observed in monolayer cultu

PURPOSE The present study evaluated the cytostatic and apoptotic effects of a 24-hr paclitaxel treatment in ovarian tumors. METHODS Three-dimensional histocultures of surgical specimens from patients (n = 17) were used. The cytostatic effect was meas

Purpose. We have shown that the three human prostate xenograft tumors, i.e. the androgen-dependent CWR22 tumor, and the androgen-resistant CWR22R and CWR91 tumors, are comparable to patient tumors in their expression of prostate specific antigen, mul

Purpose. The present study compared proliferative indices, i.e. incorporation of DNA precursor (i.e. thymidine or TdR, and bromodeoxyuridine or BrdU) and expression of proliferating cell nuclear antigen (PCNA), as molecular pharmacodynamic endpoints
