paclitaxelloaded dqasomes uj day after tumor implantation fig tumor growth relafen blood thinner inhibition study in nude mice implanted with human colon cancer cells the mean tumor volume from each group was blotted against the number of days each group involved animals for clarity, error bars were omitted note that after weeks the dose, normalized relafen blood thinner for paclitaxel, was tripled in all treatment groups empty dqasomes do not relafen blood thinner show any impact on tumor growth, paclitaxelloaded dqasomes with paclitaxel and dequalinium concentrations identical to controls seem to inhibit the tumor growth by about correspondingly, the average tumor weight in the treatment group, after sacrificing the animals days, later was approximately relafen blood thinner half of that in all controls although this result seems to suggest that dqasomes might indeed be able to increase the therapeutic potential of relafen blood thinner paclitaxel, the preliminary character of this first in vivo study has to be emphasized experiments to optimize the relafen blood thinner treatment protocol are ongoing in the authors laboratory summary since their initial relafen blood thinner description in , dqasomes and dqasomelike vesicles have been established as the first relafen blood thinner mitochondriatargeted colloidal delivery system, capable of relafen blood thinner transporting plasmid dna as well as small drug molecules towards mitochondria within living mammalian cells the further exploration of this unique mitochondriotropic delivery relafen blood thinner system will introduce new ways for the treatment of cancer and for the therapy of a multitude of mitochondrial diseases acknowledgments i am grateful relafen blood thinner to prof v p torchilin for many helpful discussions and for his strong and continuous support of my work i also would like to sincerely thank my graduate students, gerard relafen blood thinner dsouza, shingming cheng, sarathi boddapati and relafen blood thinner eyad katrangi, whose experimental work has made the writing of this chapter possible i am obliged to the muscular dystrophy association tucson, az, the united mitochondrial disease foundation pittsburgh, pa, mitovec, inc boston, ma and northeastern relafen blood thinner university boston, ma for the financial support i received from these organizations during the last four years references weissig v, lasch j, erdos g, meyer hw, rowe tc and relafen blood thinner hughes j dqasomes a novel potential drug and gene delivery system made from dequalinium pharm res � smith ra, porteous cm, gane am and murphy mp delivery of bioactive molecules to mitochondria in vivo proc natl acad sci usa murphy mp and smith ra drug delivery to mitochondria the key to mitochondrial medicine adv drug del rev muratovska a, lightowlers rn, taylor rw, wilce ia and murphy mp targeting time should take topamax large molecules to mitochondria adv drug del rev szewczyk a and wojtczak l mitochondria relafen blood thinner as a pharmacological target pharmacol rev weissig v mitochondrialtargeted drug and dna delivery crit rev ther drug carr syst weissig v, cheng sm and dsouza g mitochondrial pharmaceutics mitochondrion weissig v targeted drug delivery to mammalian mitochondria in living cells exp opin relafen blood thinner drug del weissig v, boddapati sv, dsouza ggm and cheng sm targeting of low molecular weight drugs to mammalian mitochondria drug des rev de rosa m, gambacorta a and gliozi a structure, biosynthesis, and physico chemical properties of archaebacterial lipids microbiol rev relafen blood thinner gambacorta a, gliozi a and relafen blood thinner de rosa m archaeal lipids and their biotechnological applications world j microbiol biotechnol weissig v, mogel hj, wahab m and lasch j computer simulations of dqasomes proc intl symp control rel bioact mater weissig v, lizano � and torchilin vp a micellar relafen blood thinner delivery system for dequalinium � a lipophilic cationic drug with anticarcinoma activity j lipos res weissig v, lizano c, ganellin cr and torchilin vp dna binding cationic bolasomes with delocalized charge center a structureactivity relationship study stp pharma sci chrzanowskalightowlers zm, lightowlers relafen blood thinner rn and turnbull dm gene therapy for mitochondrial dna defects is it possible?
