L-Karnitin ve Alfa-Lipoik Asitin, HCT 116 +/+ ve -/- Kolon Kanser Hücre Serilerinin Proliferasyonu Üzerindeki Sinerjetik Etkileri

L-karnitin, uzun zincirli yağ asitlerinin mitokondri matriksine transportunda yer alarak, lipid metabolizmasında önemli görevlere sahip olan bir molekül olmasının yanı sıra, serbest radikal temizleyici aktivite gösterir ve antikanser özellikler sergiler. α-Lipoik asitin, tip2 diyabet, ateroskleroz, inflamatuar deri hastalıkları ve Parkinson hastalığına karşı oldukça etkili bir molekül olduğu gösterilmiştir ve farklı kanser hücrelerinde apoptotik etkiler gösterdiği bilinmektedir. Bu çalışmada, α-Lipoik asit ve L-Karnitin’in, HCT 116 +/+ ve HCT 116 -/- kolon kanseri hücre serilerindeki sinerjetik etkileri araştırılmıştır. Bu amaçla, HCT 116 +/+ ve -/- kolon kanseri hücreleri, L-karnitin ve α-Lipoik asit ile 24 saat muamele edildikten sonra, MTT testi ve kaspaz 3-enzim aktivitesi ile hücre canlılığı ve kaspaz-3 enzim aktivitesi üzerindeki etkileri incelenmiştir. Bu çalışmada, α-Lipoik asit ve Lkarnitin’in, kombinasyon halinde verildiklerinde sinerjetik etkiler sergileyerek, HCT 116 +/+ ve -/- kolon kanseri hücrelerinin canlılığını azalttıkları ve kaspaz-3 enzim aktivitesini artırdıkları görülmüştür. L-karnitin ve α-Lipoik asitin kanser terapisindeki sinerjetik etkilerinin mekanizmasını açığa çıkarmak için daha ileri çalışmalar yapılmalıdır

It is an effective antioxidant molecule that exhibits free radical scavenging activity and it enhances antioxidant status in rats and exhibited anticancer properties. It has been shown that α-Lipoic acid is a very effective molecule against type 2 diabetes, atherosclerosis, inflammatory skin diseases, reperfusion arrhythmias and Parkinson’s disease and serves apoptotic action in different cancer cells. These molecules can display important roles in treatment of colon cancer. In this study, we examined the synergetic effects of α-lipoic acid and L-carnitine on HCT 116 +/+ and HCT 116 -/- colon cancer cell line. For this purpose, HCT 116 +/+ and -/- colon cancer cells were treated with L-carnitine and α-Lipoic acid for 24 hours and MTT assay and caspase 3 enzyme activity assay was conducted. α -Lipoic acid and L-carnitine alone or in combination decreased cell viability in HCT 116 +/+ and /- colon cancer cells and exhibited synergetic effect on the cell viability. Further studies must be conducted to find out the mechanism of their effects in cancer therapy
