BACKGROUND The DNA repair gene XPD, an important caretaker of the overall genome stability, is thought to play a major role in the development of human malignancy. Polymorphic variants of XPD, at codon 312, 751, and other sites, have been associated with cancer susceptibility, but few studies have investigated their effect on prostate cancer risk. (More)
The DNA repair gene Ku70, an important caretaker of the overall genome stability, is thought to play a major role in the DNA double strand break repair system. It is known that defects in double strand break repair capacity can lead to irreversible genomic instability. However, the polymorphic variants of Ku70 and their association with oral cancer(More)
The DNA repair gene ERCC6, an important caretaker of the overall genome stability, is thought to play a role in the development of human malignancy. However, the polymorphic variants of ERCC6, has never been reported about their association with oral cancer susceptibility. In this hospital-based case-control study, the association of ERCC6 codon 399, 1097(More)
BACKGROUND The DNA repair gene XRCC4, an important caretaker of overall genome stability, is thought to play a major role in the development of human carcinogenesis. However, the association of the polymorphic variants of XRCC4 with oral cancer susceptibility has never been reported. MATERIALS AND METHODS In this hospital-based case-control study, the(More)
The DNA double strand break repair gene XRCC4, an important caretaker of genome stability, is suggested to play a role in the development of human carcinogenesis. However, no evidence has been provided showing that XRCC4 was associated with oral oncology. In this hospital-based case-control study, the association of XRCC4 G-1394T (rs6869366), intron 3(More)
The DNA repair gene XRCC4, an important caretaker of the overall genome stability, is thought to play a major role in the human carcinogenesis. We investigate some novel and important polymorphic variants of XRCC4, at codon 247 (rs3734091), G-1394T (rs6869366), intron 3 (rs28360071), and intron 7 (rs28360317), of their associated with gastric cancer(More)

Some new and important polymorphic variants of XRCC4, at codon 247 (rs 3734091), G-1394T (rs 6869366), and Intron 7 (rs 28360317), and their association with breast cancer susceptibility was investigated(More)
The DNA repair gene X-ray cross-complementing group 4 (XRCC4), a member of the non-homologous end-joining (NHEJ) repair system, plays a major role in the repair of the double-strand breaks of the DNA sequence. This gene is critical to the maintenance of overall genome stability, and is also thought to play a key role in human carcinogenesis. In this(More)
BACKGROUND The fungus of Ganoderma is a traditional medicine in Asia with a variety of pharmacological functions including anti-cancer activities. We have purified an extracellular heteropolysaccharide fraction, PS-F2, from the submerged mycelia culture of G. formosanum and shown that PS-F2 exhibits immunostimulatory activities. In this study, we(More)
The bioactive components of Ganoderma formosanum have not yet been characterized. We investigated the immunomodulatory activities of the extracellular polysaccharides produced from a submerged mycelial culture of G. formosanum. The polysaccharides were mainly composed of d-mannose, d-galactose and d-glucose. After gel filtration chromatography, three(More)
