Identifying a bona fide population of cardiac stem cells (CSCs) is a critical step for developing cell-based therapies for heart failure patients. Previously, cardiac c-kit(+) cells were reported to be CSCs with a potential to become myocardial, endothelial and smooth muscle cells in vitro and after cardiac injury. Here we provide further insights into the(More)
Methylation levels of long interspersed nucleotide elements (LINE-1) are representative of genome-wide methylation status and play an important role in maintaining genomic stability and gene expression. To derive insight into the association between genome-wide methylation status and tetralogy of fallot (TOF), we compared the methylation status of LINE-1(More)
To examine the proper margin for breast conservative surgery in Chinese women population. 40 breast cancer specimens were collected and each sample was dissected into several groups: primary tumor group, 1 cm paracarcinoma, 2 cm paracarcinoma, 3 cm paracarcinoma and excessive 3 cm paracarcinoma groups. The immunohistochemistry staining was performed to(More)
Although a lower methylation level of whole genome has been demonstrated in Tetralogy of Fallot (TOF) patients, little is known regarding changes in specific gene DNA methylation profiles and the possible associations with TOF. In current study, the promoter methylation statuses of congenital heart defect (CHD) candidate genes were measured in order to(More)
Transforming growth factor beta (TGF-β) induces epithelial–mesenchymal transition (EMT) accompanied by cellular differentiation and migration. Despite extensive transcriptomic profiling, identification of TGF-β-inducible, EMT-specific genes during metastatic progression of lung cancer remains elusive. Here, we functionally validate a previously described(More)
NKX2-5, GATA4 and HAND1 are essential for heart development, however, little is known regarding their epigenetic regulation in the pathogenesis of tetralogy of fallot (TOF). Methylation levels were measured in three regions of NKX2-5 (M1: -1596 bp ~ -1374 bp, M2: -159 bp ~ 217 bp and M3: 1058 bp ~ 1524 bp), one region of GATA4 (M: -392 bp ~ 107 bp) and(More)
Suppression subtractive hybridization (SSH) was used to clone transcripts upregulated during heat stress in leaves of Pinellia ternata. The complementary structures of deoxyribonucleic acid (cDNAs) of heat-stressed plants were used as the “tester,” and cDNAs of unstressed plants were used as the “driver.” Sequencing the whole SSH library yielded 303(More)
Objective. Recent studies on the association between uridine diphosphosglucuronosyltransferases (UGTs) 2B17 polymorphism and risk of prostate cancer (PCa) showed inconclusive results. To clarify this possible association, we conducted a meta-analysis of published studies. Methods. We searched the published literature from PubMed, Embase, Google Scholar, and(More)
Reconstruction of unknown objects by microwave illumination requires efficient inversion for measured electromagnetic scattering data. In the integral equation approach for reconstructing dielectric objects based on the Born iterative method or its variations, the volume integral equations are involved because the imaging domain is fully inhomogeneous. When(More)
Study on ultraviolet-screening effect of extracts from mangosteen (Garcinia mangostana Linn. Cytotoxic effect of xanthones from pericarp of the tropical fruit mangosteen (Garcinia mangostana Linn.) on human melanoma cells. M. A. Shibata et al., alpha-Mangostin extracted from the pericarp of the mangosteen (Garcinia mangostana Linn) reduces tumor growth and(More)
