Telomerase inhibition and cell growth arrest by G-quadruplex interactive agent in multiple myeloma.[Pubmed:14555701]
Mol Cancer Ther. 2003 Sep;2(9):825-33.
OBJECTIVE: The aim of this study was to test the efficacy of telomerase inhibitor (TMPyP4 [tetra(N-methyl-4-pyridyl)-porphyrin chloride]; a G-quadruplex-intercalating porphyrin) as a potential therapeutic agent for multiple myeloma. MATERIALS AND METHODS: We studied telomere length, telomerase activity, and effect of telomerase inhibition in multiple myeloma cells. Several myeloma cell lines were analyzed for telomerase activity, telomere length, and gene expression. Three myeloma cell lines (U266, ARH77, and ARD) were treated with TMPyP4 for 3-4 weeks. Viable cell number was assessed by trypan blue exclusion, and nature of cell death was determined by annexin labeling and/or DNA fragmentation. In situ oligo ligation technique was used to identify specific DNase I-type DNA cleavage. RESULTS: We report high telomerase activity and shortened telomeres in myeloma cells compared to normal B cells. We have also observed inhibition of telomerase activity, reduction in telomere length, and decline of myeloma cell growth, as measured by trypan blue dye exclusion, following exposure to TMPyP4. Exposure to porphyrin reduced telomerase activity of U266, ARH77, and ARD myeloma cells by 98%, 92%, and 99%, respectively. Exposure to porphyrin had no effect on viability for the first 14 days, followed by death of 75-90% of cells over the next 2 weeks. The nature of cell death was apoptotic, as determined by annexin and DNA nick labeling. Majority of cells showed DNA fragmentation specific to caspase-3-activated DNase I. CONCLUSIONS: These results demonstrate anti-proliferative activity of G-quadruplex-intercalating agents, and suggest telomerase as an important therapeutic target for myeloma therapy.
Effect of telomere and telomerase interactive agents on human tumor and normal cell lines.[Pubmed:10741725]
Clin Cancer Res. 2000 Mar;6(3):987-93.
Shortening of telomeres along with an up-regulation of telomerase is implicated in the immortality of tumor cells. Targeting either telomeres or telomerase with specific compounds has been proposed as an anticancer strategy. Because telomerase activity and telomeres are found in normal cells, telomere or telomerase targeting agents could induce side effects in normal tissues. We evaluated the effects of telomere and telomerase interactive agents in human tumor and normal cell lines to try to determine the potential side effects those agents might induce in patients. Toxicity of the G-quadruplex interactive porphyrins (TMPyP4, TMPyP2) and azidothymidine (AZT) were tested using a cell-counting technique against normal human cell lines (CRL-2115 and CRL-2120, fibroblasts; NHEK-Ad, adult keratinocytes; CCL-241, small intestinal cells; NCM 460, colonic mucosal epithelial cells) and human tumor cell lines (MDA-MB 231 and Hs 578T, breast cancer; SK-N-FI, neuroblastoma; HeLa, cervix cancer; MIA PaCa-2, pancreatic cancer; HT-29 and HCT-116, colon cancer; DU 145, prostatic cancer cell line). Telomerase activity of these cell lines was measured by a non-PCR-based conventional assay. The effects of TMPgammaP2, TMPyP4, and AZT were also evaluated against normal human bone marrow specimens, using a granulocyte-macrophage colony-forming assay (CFU-GM). AZT showed very low cytotoxic effects against normal and tumor cell lines, with the IC50 values above 200 microM. The IC50 values for TMPyP2 and TMPyP4 in normal human cell lines were in the range of 2.9-48.3 microM and 1.7-15.5 microM, respectively, whereas in tumor cell lines the IC50 values were 11.4-53 microM and 9.0-28.2 microM, respectively. Within the tissue types, keratinocytes were more sensitive to TMPyP4 than fibroblasts, and small intestinal cells were more sensitive than colonic mucosal epithelial cells. The IC50 for TMPyP2 and TMPyP4 in the normal marrow colony-forming assays were 19.3 +/- 5.1 microM and 47.9 +/-1.0 microM, respectively. In conclusion, the in vitro cytotoxicity of the telomere interactive agent TMPyP4 is comparable in human tumor and normal cell lines, which indicates that TMPyP4 could have effects on normal tissues.
