    Combined Germline Variations of Thrombophilic Genes Promote Genesis of Lung Cancer
    (Asian Pacific Organization Cancer Prevention, 2013) Ozen, Filiz; Polat, Fikriye; Arslan, Sulhattin; Özdemir, Öztürk
    Background: A large variety of familiar and non-familiar lung carcinomas (LC) are caused by long term exposure to chemical carcinogens that are present in tobacco smoke. We aimed to investigate the prevalence of 5 thrombophilic germ-line mutations in patients with lung carcinomas. Materials and Methods: A total of 52 LC patients and 212 healthy controls from same population were analyzed for FV Leiden, factor V H1299R (R2), PAI-1, MTHFR C677T, MTHFR A1298C, ACE I/D, and Apo E genes and compared. Results: Overall, heterozygous and/or homozygous point mutations in FV Leiden Apo E2, PAI-1 and MTHFR C677T genes were associated with LC in the current cohort. There was no meaningful association between LC and ACE I/D gene markers. Conclusions: The current results showed that LC is related to combined thrombophilic gene mutations and individuals with homozygosity of 4G in PAI-1 and MTHFR C677T genes and heterozygosity of FV Leiden, Apo E4 genes have a germ-line risk for LC tumorigenesis.

    The effect of 3-methylcholanthrene and butylated hydroxytoluene on glycogen levels of liver, muscle, testis, and tumor tissues of rats
    (Tubitak Scientific & Technological Research Council Turkey, 2013) Polat, Fikriye; Dere, Egemen; Gul, Eylem; Yelkuvan, Izzet; Özdemir, Öztürk; Bingol, Gunsel
    This study examined the effects of separate and combined applications of 3-methylcholanthrene, a polycyclic aromatic hydrocarbon and potent carcinogenic agent, and butylated hydroxytoluene, the antioxidant food additive, on the glycogen levels of liver, muscle, testis, and tumor tissues in rats. Adult male Wistar albino rats weighing 100-110 g at 8 weeks of age were used in this study. This study consisted of a control group (n = 9) and 3 different experiment groups in which rats were chronically treated with 3-methylcholanthrene (n = 9) or butylated hydroxytoluene (n = 11) or a combination of these agents (n = 14). Rats were intraperitoneally injected with a 200 mg kg(-1) dose of butylated hydroxytoluene and a 40 mg kg-1 dose of 3-methylcholanthrene. At the end of the 26-week experimental period, tissues of rats killed via cervical dislocation were placed in 10% trichloroacetic acid for glycogen determination. Our results showed that the administration of 3-methylcholanthrene, butylated hydroxytoluene, and 3-methylcholanthrene + butylated hydroxytoluene caused statistically significant changes in the glycogen levels of liver, muscle, and testis tissues, and glycogen was stored in tumor tissue.
