Using a sigmoidoscopy-based case-control study (753 cases, 799 controls) in Los Angeles County, we investigated the potential modifier role in the effect of alcohol and smoking of single-nucleotide polymorphisms (SNP) in three DNA repair genes, XRCC1 (Arg194Trp and Arg399Gln), XRCC3 (Thr241Met), and XPD (Lys751Gln). We have previously reported an inverse association between the XRCC1 codon 399 ...
Diets high in red meat have been consistently associated with colorectal cancer (CRC) risk and may result in exposure to carcinogens that cause DNA damage [i.e polycyclic aromatic hydrocarbons, heterocyclic amines (HCAs) and N-nitroso compounds]. Using a family-based study, we investigated whether polymorphisms in the nucleotide excision repair (NER) (ERCC1 3' untranslated region (UTR) G/T, XPD...
We report the association of levels of urinary arsenic (As) compounds (arsenite (AsIII), arsenate (AsV), monomethylarsonic acid (MMAV), dimethylarsinic acid (DMAV), and arsenobetaine (AB)) with genetic polymorphisms of candidate genes, glutathione S-transferase omega 1 (GSTO1) and 2 (GSTO2), mu 1 (GSTM1), and theta 1 (GSTT1), arsenic (+3 oxidation state) methyltransferase (AS3MT), methylenetetr...
PURPOSE To analyze the association of the polymorphisms of xeroderma pigmentosum complementation group D (XPD) and 8-oxoguanine glycosylase-1 (OGG1) genes with the risk of age-related cataract (ARC) in an Egyptian population. METHODS This case-control study included 150 patients with ARC and 50 controls. Genotyping of XPD Asp³¹²Asn was performed by amplification refractory mutation system PCR...
Cataracts are the major eye disorder and have been associated mainly with mutations in lens-specific genes, but cataracts are also frequently associated with complex syndromes. In a large-scale high-throughput ENU mutagenesis screen we analyzed the offspring of paternally treated C3HeB/FeJ mice for obvious dysmorphologies. We identified a mutant suffering from rough coat and small eyes only in ...
This study aimed to investigate the associations of XPC c.2815A>C, XPD c.934G>A and c.2251A>C, XPF c.2505T>C and ERCC1 c.354C>T single nucleotide polymorphisms (SNPs) of nucleotide excision repair pathway in outcome of head and neck squamous cell carcinoma (HNSCC) patients treated with cisplatin (CDDP) chemoradiation. Patients with XPC c.2815AC or CC and XPD c.934GA or AA genotypes had 0.20 and...
BACKGROUND 8-oxoG, a common DNA lesion resulting from reactive oxygen species (ROS), has been shown to be associated with cancer initiation. hOGG1 DNA glycosylase is the primary enzyme responsible for excision of 8-oxoG through base excision repair (BER). Integrins are members of a family of cell surface receptors that mediate the cell-cell and extracellular matrix (ECM) interactions. Integrins...
Mms19 encodes a cytosolic iron-sulfur assembly component. We found that Drosophila Mms19 is also essential for mitotic divisions and for the proliferation of diploid cells. Reduced Mms19 activity causes severe mitotic defects in spindle dynamics and chromosome segregation, and loss of zygotic Mms19 prevents the formation of imaginal discs. The lacking mitotic tissue of Mms19 larvae can be rescu...
