The N-myc downstream-regulated gene 1 (ndrg1) is highly expressed in N-myc knock-out mice through an unknown regulatory mechanism. As one member of the human NDRG gene family, NDRG2 encodes a protein highly homologous to Ndrg1. However, it is uncertain whether the expression of human NDRG2 is regulated by Myc because mouse ndrg2 and -3 are not affected by(More)
MicroRNAs, a large family of small regulatory RNAs, are posttranscriptional gene regulators that bind mRNA in a sequence-specific manner, thereby controlling diverse aspects of cell function, including immune reaction. In this study, we screened and identified a group of differentially expressed miRNAs in naive and activated CD4(+) T cells. Among the miRNAs(More)
BACKGROUND AND OBJECTIVE Yes-associated protein (YAP) and transcriptional co-activator with PDZ-binding motif (TAZ) are nuclear effectors of the Hippo pathway. Although they are abundantly expressed in the cytoplasm and nuclei of human colorectal cancer (CRC), and related to tumor proliferation status, there have been few studies on the predictive role of(More)
Resistance to trastuzumab and concomitantly distal metastasis are leading causes of mortality in HER2-positive breast cancers, the molecular basis of which remains largely unknown. Here, we generated trastuzumab-resistant breast cancer cells with increased tumorigenicity and invasiveness compared with parental cells, and observed robust(More)
HLA-G and HLA-E are non-classical HLA Ib molecules. Recently, increasingly more reports have shown that HLA-G is highly expressed in different malignancies. In this article, we detected the expression levels of HLA-G and HLA-E in primary colorectal cancer patients. Our results showed that 70.6% and 65.7% of the colorectal cancer tissues had positive HLA-G(More)
Epigenetic histone modifications play critical roles in the control of self-renewal and differentiation of hematopoietic stem cells (HSCs). Mysm1 is a recently identified histone H2A deubiquitinase with essential and intrinsic roles for maintaining functional HSCs. In this study, in addition to confirming this function of Mysm1, by using Mysm1-deficient(More)
Metastasis is the major reason for the death of patients suffering from malignant diseases such as human hepatocellular carcinoma (HCC). Among the complex metastatic process, resistance to anoikis is one of the most important steps. Previous studies demonstrate that microRNA-26a (miR-26a) is an important tumor suppressor that inhibits the proliferation and(More)
OBJECTIVE To study the protection of NT3 gene transfection on the guinea pig cochlea treated with gentamicin. METHOD The liposome plasmid complex (pIRES2-EGFP-NT3) was injected into the guinea pig cochlea, then the guinea pigs were treated with gentamicin (120 mg/kg, 14 d). The DPOAE and ABR were measured at 1 d and 2 w after stop the gentamicin and the(More)
A single microRNA (miRNA) can regulate expression of multiple proteins, and expression of an individual protein may be controlled by numerous miRNAs. This regulatory pattern strongly suggests that synergistic effects of miRNAs play critical roles in regulating biological processes. miR-9 and miR-124, two of the most abundant miRNAs in the mammalian nervous(More)
BACKGROUND Previous work has shown reduced expression levels of let-7 in lung tumors. But little is known about the expression or mechanisms of let-7a in prostate cancer. In this study, we used in vitro and in vivo approaches to investigate whether E2F2 and CCND2 are direct targets of let-7a, and if let-7a acts as a tumor suppressor in prostate cancer by(More)
