Journal Article
Efficacy of liposomes and hyperthermia in a human tumor xenograft model: importance of triggered drug release.
Garheng Kong,Gopal Anyarambhatla,William P. Petros,R. D. Braun,Colvin Om,David Needham,Mark W. Dewhirst +6 more
TL;DR: With HT, the DOX concentrations and fluorescence were tightly correlated with tumor growth delay, indicating that adequate (increased) drug delivery can be predictive of therapeutic effect and demonstrates the importance of rapid drug release from the drug carriers at the tumor site.
Journal ArticleDOI
DNA mismatch repair and O6-alkylguanine-DNA alkyltransferase analysis and response to Temodal in newly diagnosed malignant glioma.
Henry S. Friedman,Roger E. McLendon,Tracy Kerby,M Dugan,Sandra H. Bigner,AJ Henry,David M. Ashley,J Krischer,Shelley Lovell,Karima Rasheed,F Marchev,AJ Seman,Ilkcan Cokgor,Jeremy N. Rich,Elizabeth S. Stewart,Colvin Om,James M. Provenzale,Darell D. Bigner,Michael M. Haglund,Allan H. Friedman,Paul Modrich +20 more
TL;DR: Temodal has activity against newly diagnosed GBM and AA and warrants continued evaluation of this agent, and pretherapy analysis of tumor DNA mismatch repair and, particularly, AGT protein expression may identify patients in whom tumors are resistant to Temodal.
Journal Article
Experimental chemotherapy of human medulloblastoma cell lines and transplantable xenografts with bifunctional alkylating agents.
Henry S. Friedman,Colvin Om,Stephen X. Skapek,Susan M. Ludeman,Gertrude B. Elion,S. C. Schold,P. F. Jacobsen,Lawrence H. Muhlbaier,Darell D. Bigner +8 more
TL;DR: The results extend the previous studies demonstrating the antitumor activity of nitrogen and phosphoramide mustard-based bifunctional alkylating agents in the treatment of human medulloblastoma continuous cell lines and transplantable xenografts, and support the continued use of these agents in clinical trials.
Journal Article
Cyclophosphamide resistance in medulloblastoma.
Henry S. Friedman,Colvin Om,Scott H. Kaufmann,Susan M. Ludeman,N. Bullock,Darell D. Bigner,Griffith Ow +6 more
TL;DR: The results suggest that 4-HC resistance in medulloblastoma can be multifactorial and multiple distinct mechanisms of resistance were demonstrated.
Journal ArticleDOI
A structural basis for a phosphoramide mustard-induced DNA interstrand cross-link at 5'-d(GAC).
Qing Dong,Daniel Barsky,Michael E. Colvin,C.F. Melius,Susan M. Ludeman,J F Moravek,Colvin Om,Darell D. Bigner,Paul Modrich,Henry S. Friedman +9 more
TL;DR: While the enthalpies of 1,2 and 1,3 mustard cross-linked DNA were found to be very close, a 1, 3 structure was more flexible and may therefore be in a considerably higher entropic state.
