Nanosized liposomal drug delivery systems are well suited for selective drug delivery at tumor sites. Celecoxib (CLX) is a highly hydrophobic cyclooxygenase-2 inhibitor that can reduce the incidence of colorectal polyps; however, the adverse cardiovascular effects limit its applicability. Here, we report a liposomal formulation of CLX using 1,2-Distearoyl-sn-glycero-3-phosphocholine, cholesterol, and polyethylene glycol. Encapsulation efficiency of the drug was greater than 70%; the release was slow and sustained with only 12%-20% of CLX released in the first 12h. Flow cytometry and confocal microscopy studies using the colon cancer cell lines HCT-116 and SW620 showed significantly higher cellular association and internalization of the liposomes after incubation for 6h when compared with 30min. The liposomes did not colocalize with transferrin, but had a punctuate appearance, indicating vesicular localization. Cell proliferation was inhibited by 95% and 78%, respectively, in SW620 and HT29 cells after incubation with 600M liposomal CLX for 72h. Moreover, cellular motility, as shown by a scratch wound healing assay, was also significantly (p=0.006) inhibited when SW620 cells were incubated with 400M liposomal CLX. This is the first report of the successful encapsulation of CLX in a long-circulating liposomal formulation that could be effective against colorectal cancer.

UV responsive drug delivery from suprofen incorporated liposomes Demirbağ, Birsen; Hasırcı, Vasıf Nejat; Hasırcı, Nesrin; Department of Biotechnology (2011) Drug delivery systems are designed to achieve low, local doses at the target site. Delivery systems can provide the drug in a continuous manner or in response to environmental stimuli such as temperature, pH or UV. This study aimed to develop photosensitive liposomes that achieve UV-responsive release of their content. The main mechanism was to incorporate a light sensitive molecule into the liposomal bilayer then achieve destabilization of the membrane by exposure to UV. This would result in an on demand r...
Biopolymer based micro/nanoparticles as drug carriers for the treatment of skin diseases Eke, Gözde; Hasırcı, Vasıf Nejat; Hasırcı, Nesrin; Department of Micro and Nanotechnology (2011) Controlled drug delivery systems are becoming increasingly interesting with the contribution of nanotechnology. In the case of transdermal applications the greatest limitation is the highly impermeable outermost layer of the skin, the stratum corneum. One promising method of controlled transdermal drug delivery of the skin therapeutics is the use of nanoparticles as carriers. Encapsulation of the drug, as opposed to classical topical application of creams or emulsions, allows the drug to diffuse into hair f...
Synthesis of Doxorubicin loaded magnetic chitosan nanoparticles for pH responsive targeted drug delivery ÜNSOY, GÖZDE; Khodadust, Rouhollah; Yalcin, Serap; Mutlu, Pelin; Gündüz, Ufuk (2014-10-01) Targeted drug delivery is a promising alternative to overcome the limitations of classical chemotherapy. In an ideal targeted drug delivery system carrier nanoparticles would be directed to the tumor tissue and selectively release therapeutic molecules. As a novel approach, chitosan coated magnetic nanoparticles (CS MNPs) maintain a pH dependent drug delivery which provides targeting of drugs to the tumor site under a magnetic field. Among various materials, chitosan has a great importance as a pH sensitive...
Controlled doxorubicin delivery from photoresponsive liposomes carrying vitamin A derivatives / Heper, Senem; Hasırcı, Vasıf Nejat; Hasırcı, Nesrin; Department of Biotechnology (2014) Drug delivery systems (DDS) have been an attractive approach to eliminate the drawbacks of conventional drug administration. Controlled and photoresponsive drug delivery systems have a special advantage; they deliver drugs more effectively. Liposomes are mostly preferred as drug carriers due to their ability to carry both hydrophilic and hydrophobic drugs, their being non-toxic and non-immunogenic. In this study, photoresponsive liposomes were prepared by incorporating vitamin A derivatives into the lipid b...
Loading of Gemcitabine on chitosan magnetic nanoparticles increases the anti-cancer efficacy of the drug PARSIAN, Maryam; UNSOY, Gozde; Mutlu, Pelin; Yalcin, Serap; Tezcaner, Ayşen; Gündüz, Ufuk (2016-08-05) Targeted delivery of anti-cancer drugs increase the efficacy, while decreasing adverse effects. Among various delivery systems, chitosan coated iron oxide nanoparticles (CsMNPs) gained attention with their biocompatibility, biodegradability, low toxicity and targetability under magnetic field. This study aimed to increase the cellular uptake and efficacy of Gemcitabine.
