“Foamy virus selleck contains two promoters, which are the canonical long terminal repeat (LTR) promoter and the internal promoter
(IP). FV gene expression was considered to initiate at the internal promoter. However, little was known about how basal transcription of IP was triggered by the host cellular factors. Previous studies found some cellular proteins could affect HFV viral replication, but it was no known whether the AP1 signal pathway was involved in the activation of viral replication or not. In this study, we reported that treatment with TPA or AP1 increased basal transcription of IP and did not affect basal transcription of the promoter in the LTR. In addition, the c-Jun mutant blocked the IP activity stimulated by TPA. Two AP1 binding sites located in BFV-IP promoter were found by bioinformatics and mutants of two AP1 binding sites decreased luciferase reporter activity of IP activated by AP1. EMSA assay showed that two AP1 binding sites could bind to c-Jun/c-Fos heterodimeric. Napabucasin We also found TPA and AP1 enhanced BFV3026 replication. Taken together, these data suggested that AP1 was a positive regulator
of BFV internal promoter. (c) 2009 Elsevier B.V. All rights reserved.”
“Background and purpose: Local treatment for non-metastatic Ewing’s sarcoma family tumors (ESFTs) is controversial. Results achieved in a single institution in patients with ESFT of the humerus are presented.\n\nMaterials and methods: Patients treated between 1983 and 2000 for ESFT of the humerus were included. The impact of local treatment (surgery, radiotherapy or both) on outcome was assessed.\n\nResults: 55 patients: 34 males (62%); 21 females (38%); mean age: 17.9 (range: 3-40). Local treatment: surgery in 27 patients (49%), radiotherapy in 17 (31%) and surgery followed by radiotherapy in 11 (20%). After a mean follow-up of 15 years (range: 7-25 years), 27 patients (49%) remained continuously disease free, 27 (49%) relapsed and one died of chemotherapy toxicity. The local recurrence rate was 13% overall: 18% (3/17) after radiotherapy, 7% (2/27) after surgery and 19% (2/11)
ZD1839 after surgery followed by adjuvant radiotherapy (p = ns). On the contrary, the 10-year EFS resulted significantly higher after surgery (64%) than radiotherapy (18%, p < 0.01). The 10-year EFS after surgery followed by radiotherapy was 45%, non-significantly different from EFS of surgery or radiotherapy alone. The 3 treatment groups had a similar distribution of the most important prognostic variables for ESFT, except for the tumor-bone ratio, which was higher for patients who underwent radiotherapy, and surgical margins, more frequently inadequate in patients treated with a combination of radiotherapy and surgery compared to those managed by surgery alone.\n\nConclusions: In conclusion this study shows that in EFST of the humerus Surgery is the best treatment for small tumors.
