Although the first mouse embryonic stem (ES) cell lines were derived 25 years ago using feeder-layer-based blastocyst cultures, subsequent efforts to extend the approach to other mammals, including both laboratory and domestic species, have been relatively unsuccessful. The most notable exceptions were the derivation of non-human primate ES cell lines(More)
Selective maintenance of genomic epigenetic imprints during pre-implantation development is required for parental origin-specific expression of imprinted genes. The Kruppel-like zinc finger protein ZFP57 acts as a factor necessary for maintaining the DNA methylation memory at multiple imprinting control regions in early mouse embryos and embryonic stem (ES)(More)
The chemokine receptor CXCR4 and its ligand stromal cell-derived factor 1 (SDF-1) plays an important role in tumor progression and are associated with angiogenesis. Meanwhile, the implications of C23 in multiple signaling pathways have been also investigated. However, the effects of C23 on CXCR4 pathway in glioblastoma are not fully characterized. In the(More)
Transforming growth factor-β (TGF-β) is considered to be one of the main factors responsible for glioblastoma tumorigenesis. MicroRNAs have recently been shown to regulate cell proliferation, differentiation, and apoptosis. However, the involvement of miRNA-146a in TGF-β1-induced glioblastoma development remains largely unknown. Here, miRNA-164a(More)
Chemokine receptor CXCR4 has been identified to affect glioma progression by dominating cancer cell survival, proliferation, and migration in vitro recently. However, the implications and utilities of CXCR4 in clinical grade and prognosis were rarely reported. Thus, it is essential to carry out a meta-analysis to draw a convincing conclusion. The relevant(More)
The epidermal growth factor (EGF) pathway has been reported as canonical causes in cancer development. Meanwhile, the involvement of C23 in multiple signaling pathways has been also investigated (Lv et al., 2014). However, the effect of C23 on EGF pathway in glioblastoma is not fully characterized. In the present study, C23 and the epidermal growth factor(More)
Up to now, survivin has been recommended as a prognostic and diagnostic indicator in glioma patients. However, there are still many controversies. Here, a meta-analysis was conducted to draw a more definitive conclusion on the correlation of survivin with overall survival (OS), age, gender, and WHO grade. Eligible studies were available through careful(More)
This study aimed to investigate the overall prevalence of human papillomavirus (HPV) infection among women examined at a hospital in Harbin and to evaluate the impact of HPV types on the natural outcome and state of cervical cytology. A total of 2,938 female outpatients from the affiliated hospital of Harbin Medical University were enrolled. Rapid(More)
T cells and B cells participate in the pathogenesis of COPD. Currently, NK cells and NKT cells have gained increasing attention. In the present study, 19 COPD patients and 12 healthy nonsmokers (HNS) were recruited, and their pulmonary function was assessed. The frequencies of CD3(+) T, CD4(+) T, CD8(+) T, B, NK, and NKT-like cells were determined using(More)
This article has been retracted at the request of the Editor-in-Chief and the Publisher. The article shows evidence of irregularities in authorship during the submission process. There is strong reason to believe that the peer review process was compromised and the authors have plagiarized parts from the following article: clinicopathological significance(More)
