Background and purpose: The human multidrug resistance gene (MDR1) encodes for P-glycoprotein (P-gp) which is a transmembrane transporter protein acts as an efflux pump for a number of xenobiotics. It plays a protective role for cells against DNA damage caused by toxins and drugs. The wobble C3435T polymorphism at exon 26 has been associated with different expression levels and activities of th...

BACKGROUND The association between HER2 Ile655Val single nucleotide polymorphism and cancer is controversial. OBJECTIVES The aim of our study was to investigate this polymorphism in patients with ovarian cancer. PATIENTS AND METHODS Genomic DNA was extracted from peripheral blood leukocytes of 107 patients and 130 healthy women. HER2 gene polymorphism was assessed by PCR-RFLP. RESULTS No ...

We present the analysis of an intronic polymorphism of the nephrin gene and its relationship to the development of diabetic nephropathy in a study of diabetes type 1 and type 2 patients. The frequency of the single nucleotide polymorphism rs#466452 in the nephrin gene was determined in 231 patients and control subjects. The C/T status of the polymorphism was assessed using restriction enzyme di...

BACKGROUND: Interaction between estrogen and receptor (ER) takes part in the regulation differentiation of breast tumorigenesis. Some ERα polymorphisms, including rs3798577, are reported to be associated with risk aggressiveness carcinoma since site was targeted by microRNA, which can further modulate expression. Hence, this study conducted disclose possible role SNP rs3798577 on patients.METHO...

BACKGROUND Recent data indicate that the rs1080985 single nucleotide polymorphism of the cytochrome P450 (CYP) 2D6 gene may affect the response to treatment with donepezil in patients with Alzheimer's disease. There is also evidence that the common apolipoprotein E (APOE) polymorphism may affect the response to treatment with donepezil in Alzheimer's disease. We investigated the association bet...

The tinman (tin) and bagpipe (bap) genes are members of the NK homeobox gene family of Drosophila, so that tin occupies a higher position than bap in the regulatory hierarchy. Little is known about the level and pattern of genetic polymorphism in homeobox genes. We have analyzed nucleotide polymorphism in 27 strains of Drosophila melanogaster and one each of D. simulans and D. sechellia, within...
