Investigation of the effects of drugs effective on PI3K-AKT signaling pathway in colorectal cancer alone and in combination
Abstract
Abstract
Aim. This study was designed to determine the agent and/or possible agent combinations that may be effective in the treatment of colorectal cancer. For this reason the single and combined antiproliferative effects of NVPBEZ-235, API-1, LY 294002 and PP242 which target PI3K/AKT pathway well known to have an important role in pathophysiological mechanisms of colorectal cancer were investigated. We investigated whether NVPBEZ-235, API-1 and PP242 have antiproliferative effects which have not been studied on this cancer type and also compared the effects with LY294002 known to have antiproliferative effect on colorectal cancer. Method. DLD-1 cell line was used as colorectal cells. Real time cell analysis (xCELLigence system) was used to determine the effects of the agents in colorectal cell proliferation. Results. When the agents were applied alone, PI3K/mTOR dual inhibitor NVP-BEZ had the strongest cytotoxic effect and PI3K inhibitor LY294002 had the lowest cytotoxic effect. None of the combinations were not superior compared to alone applications. Conclusion. This study indicates that when PI3K/AKT pathway is targeted, instead of combined treatment, targeted specific treatment with a single agent having higher affinity and effectiveness would be more appropriate. Also among the agents effecting PI3K/AKT pathway especially, NVP-BEZ for targeted therapy can be alternative to conventional treatments.

Özet
Amaç. Bu çalışma kolorektal kanser tedavisinde etkili madde ve/veya olası madde kombinasyonlarını belirlemek için tasarlanmıştır. Bu nedenle kolorektal kanserin patofizyolojik mekanizmalarında önemli bir rol oynadığı bilinen PI3K/Akt yolağını hedef alan NVPBEZ-235, API-1, LY 294002 ve PP242’nin tek ve kombinasyon halinde anti-proliferatif etkileri araştırıldı. Daha önce bu kanser tipinde çalışılmayan NVPBEZ-235, API-1 ve PP242’nin anti-proliferatif etkilerinin olup olmadığı araştırıldı. Ayrıca bu etkileri kolorektal kanser üzerinde anti-proliferatif bir etkiye sahip olduğu bilinen LY 294002 ile karşılaştırıldı. Yöntem. DLD-1 hücre hattı kolorektal hücre olarak kullanıldı. Gerçek zamanlı hücre analizi (XCELLigence sistemi) kolorektal hücre çoğalmasında ajanların etkilerini belirlemek için kullanıldı. Bulgular. Maddeler tek başına uygulandığı zaman NVPBEZ-235, dual PI3K/mTOR inhibitörü NVP-BEZ en güçlü sitotoksik etkiye ve PI3K inhibitörü LY294002 en düşük sitotoksisiteye sahipti. Kombinasyonların hiçbiri, tek başına uygulamaları ile karşılaştırıldığında daha üstün değildi. Sonuç. Bu çalışma PI3K/Akt yolağı hedef alındığında, kombine tedavi yerine daha yüksek afinitesi ve etkinliği olan tek bir madde ile hedefe yönelik spesifik tedavinin daha uygun olacağını göstermektedir. Ayrıca özellikle PI3K/Akt yolağını etkileyen maddeler arasında NVP-BEZ hedefe yönelik tedavide geleneksel tedaviler için bir alternatif olabilir.
