OBJECTIVE
We aimed to study the potential role of GSTM1 and GSTT1 in the risk of osteosarcoma in Chinese population.
METHODS
We collected 110 osteosarcomas by pathologic examination and 226 controls from the First Affiliated Hospital of Harbin Medical University during December 2008 to December
Osteosarcoma is the most common primary bone malignancy in children and adolescents, and its clinical outcome is poor. We evaluated the influence of GSTP1, ERCC1 and ERCC2 polymorphisms on response to chemotherapy among osteosarcoma patients, and the significnace of these genes for prognosis. A
In this study we describe a relationship between the percentage of tumor cells staining positive for GST pi and the response to cisplatin treatment in dogs with appendicular osteosarcoma. Clinical resistance to platinum compounds has been attributed to tumor cell resistance to the drug. An
Tumor gene polymorphisms are often associated with individual susceptibility to genetic diseases. Cytochrome P4501A1 (CYP1A1) and glutathione S-transferase mu 1 (GSTM1) gene polymorphisms are closely related to the susceptibility of the body to chemical carcinogens in the environment. Therefore, we
BACKGROUND
Osteosarcoma is the most common malignant bone tumor in children and adolescents. Multidrug resistance and poor clinical outcome are the problems that still affect osteosarcoma patients. The glutathione S-transferase supergene family includes several genes that encode enzymes involved in
Osteosarcoma and chondrosarcoma are malignant bone tumors, and they significantly affect the life quality of patients including children and adults. The main treatment method is surgical amputation of the malignant lesion, despite that recurrence often occurs. Recently, it has been observed that
Reactive oxygen species are engaged in the process of carcinogenesis. It was found that oxidative stress level is significantly elevated in children with neoplasms. Moreover, their antioxidant barrier is deficient and does not control free radical reactions. Protein carbonyl groups are a well known
Toxic oxygen free radicals have been implicated as important pathologic mediators in carcinogenesis. Several reports have found antioxidants and enzymes related to the antioxidants function at increased or decreased levels in blood of patients with cancers. In previous publications we observed that
Current orthopedic implants have several problems that include poor osseointegration for extended periods of time, stress shielding and wear debris-associated bone cell death. In addition, numerous patients receive orthopedic implants as a result of bone cancer resection, yet current orthopedic
Osteosarcoma (OS) is the most common malignant bone tumor found in children. Currently, researchers have focused on protein and gene levels, while the associated metabolic variations have been poorly understood. In this study, we used a gas chromatography mass spectrometry approach and profiled
Osteosarcoma is the most common primary malignant bone tumor. Raddeanin A (RA) is an active oleanane-type triterpenoid saponin extracted from the traditional Chinese herb Anemone raddeana Regel that exerts antitumor activity against several cancer types. However, the effect of RA on osteosarcoma
OBJECTIVE
Osteosarcoma is a common primary malignant bone tumor that mainly occurs in childhood and adolescence. Despite developments in the diagnosis and treatment of osteosarcoma, the prognosis is still very poor. Cinobufagin is an active component in the anti-tumor Chinese medicine called "Chan
