Osteosarcoma is the most common primary bone malignancy in children and adolescents, and its clinical outcome is poor. We evaluated the response of GSTP1, ERCC1 and ERCC2 to chemotherapy among osteosarcoma patients, and the role of these genes on the prognosis of osteosarcoma. 187 patients with osteosarcoma were administered with methotrexate, cisplatin/adriamycin, actinomycin D, cyclophosphamide, or vincristine treatment. GSTP1, ERCC1 and ERCC2 polymorphism was genotyped by PCR-RFLP assay. The results showed the average survival time of 187 patients were 38.4 months. 97 patients showed response to neoadjuvant chemotherapy. The GSTP1 Val and ERCC2 A/A genotypes had significantly higher rates of response to chemotherapy, with adjusted OR (95% CI) of 2.19 (1.15-6.21) and 2.88 (1.14-13.25). Individuals with ERCC2 A/A genotype were likely to have a lower risk of death from oseosarcoma, and the adjusted HR was 0.32 (0.13-0.95). Our study indicated test of GSTP1 and ERCC2 Lys751Gln polymorphisms might be a candidate pharmacogenomic factors to be explored in the future to identify the osteosarcoma patients who might benefit from chemotherapy.

A new CRT binding factor (CBF) gene designated Cbcbf25 was cloned from Capsella bursa pastoris, a wild grass, by the rapid amplification of cDNA ends (RACE). The full-length cDNA of Cbcbf25 was 898 bp with a 669 bp open reading frame (ORF) encoding a putative DRE/CRT (LTRE)-binding protein of 223 amino acids. The predicted CbCBF25 protein contained a potential nuclear localization signal (NLS) in its N-terminal region followed by an AP2 DNA-binding motif and a possible acidic activation domain in the C-terminal region. Bioinformatic analysis revealed that Cbcbf25 has a high level of similarity with other CBF genes like cbfl, cbf2, and cbf3 from Arabidopsis thaliana, and Bncbf5, Bncbf7, Bncbfl6, and Bncbfl7 from Brassica napus. A cold acclimation assay showed that Cbcbf25 was expressed immediately after cold triggering, but this expression was transient, suggesting that it concerns cold acclimation. Our study implies that Cbcbf25 is an analogue of other CBF genes and may participate in cold-response, by for example, controlling the expression of cold-regulated genes or increasing the freezing tolerance of plants.

Background: We examined changes in hepatitis B core-related antigen (HBcrAg) during the four sequential phases of chronic hepatitis B virus (HBV) infection: hepatitis B e antigen (HBeAg)-positive chronic infection (EPCI) and hepatitis (EPCH), followed by HBeAg-negative chronic infection (ENCI) and hepatitis (ENCH). We compared the performance of serum HBcrAg, hepatitis B surface antigen (HBsAg), and HBV DNA in predicting EPCH and ENCH.
