Alleviation of the drug-resistant phenotype in idarubicin and cytosine arabinoside double-resistant acute myeloid leukemia cells by indomethacin.
Chemoresistance to anticancer drugs is a major issue in the successful treatment of acute myeloid leukemia (AML). In this study, we developed an AML cell line (AML-2/IDAC) that is resistant to treatment with a combination of […]
Biodistribution and efficacy of [131I]A33scFv::CDy, a recombinant antibody-enzyme protein for colon cancer.
In antibody-directed enzyme-prodrug therapy (ADEPT), an antibody-bound enzyme localizes to tumor tissue, where it selectively converts a subsequently administered non-toxic prodrug into a cytotoxic drug. A33scFv::CDy is a bifunctional fusion construct comprising a single chain antibody against the gpA33 antigen and […]
Finasteride induces apoptosis via Bcl-2, Bcl-xL, Bax and caspase-3 proteins in LNCaP human prostate cancer cell line.
We investigated the effects of finasteride, a 5alpha-reductase inhibitor, on cell death machinery through the induction of apoptosis in an in vitro model for prostate cancer. Finasteride treatment of the LNCaP hormone-dependent human prostate cancer cell […]
Growth associated proteins in tumor cells and stroma related to disease progression of colon cancer accounting for tumor tissue PGE2 content.
Connections among specific proteins (Bax, Bcl-2, bFGF, COX-1, COX-2, E-cad, p15, p53, PCNA, TGFbeta3, TUNEL, vWF) in control of cell proliferation, apoptosis, cell adhesion, tumor vascularity and PGE2 content were evaluated in […]
Theranostic proteomic profiling of cyclins, cyclin dependent kinases and Ras in human cancer cell lines is dependent on p53 mutational status.
Despite major advances in the molecular biology of the cancer cell over the past two decades, the great majority of patients are still treated by conventional cytotoxic drugs. The chemotherapy regimens employed […]
Hemoglobin-associated proteins isolated from blood serum of Ehrlich carcinoma-bearing mice.
In the present study, we analyzed differential composition of blood serum from Ehrlich carcinoma-bearing and healthy male C57Bl/6 mice by isolating complexes of hemoglobin and other serum proteins by a proteomic approach (gel filtration, gel electrophoresis, and mass spectrometry). The hemoglobin fractions isolated […]
Functional analysis of NKX3.1 in LNCaP prostate cancer cells by RNA interference.
The function of the androgen-regulated homeobox protein NKX3.1 in prostate cancer is controversial. NKX3.1 is necessary for correct prostate development and undergoes frequent allelic loss in prostate cancer. However, no mutations occur in the coding region and some particularly aggressive cancers […]
Induction of apoptosis by thiosulfinates in primary human prostate cancer cells.
Thiosulfinates, a substance of Allium tuberosum L., is a known folk medicine that has been extensively used in diet to treat diseases. In the present study, we have evaluated the effect of thiosulfinates from Allium tumberosum L. on proliferation of metastasis (DU145) […]
Kinetics and subcellular localization of 5-ALA-induced PpIX in DHL cells via two-photon excitation fluorescence microscopy.
Two-photon excitation fluorescence (TPEF) microscopy was used to measure the 5-aminolevulinic acid (5-ALA)-induced PpIX fluorescence in follicular lymphoma DHL cells. Kinetics of 5-ALA-induced PpIX accumulation in DHL cells under various 5-ALA concentrations was studied. We found that during […]
Hyperthermia switches glucose depletion-induced necrosis to apoptosis in A549 lung adenocarcinoma cells.
Both cellular and clinical studies have shown that hyperthermia is one of the most potent sensitizers for the action of ionizing radiation. Although hyperthermic improvement in clinical outcome is suggested to be linked to its ability to induce cell cycle arrest […]
