We have mapped conserved regions of enhanced DNase I accessibility within the endogenous chromosomal locus of vascular endothelial growth factor A (VEGF-A). Synthetic zinc finger protein (ZFP) transcription factors were designed to target DNA sequences contained within the DNase I-hypersensitive regions. These ZFPs, when fused to either VP16 or p65(More)
The objective of the current study was to investigate the toll-like receptors (TLR), including the soluble forms sTLR2 and sTLR4, involved in innate immune responses of dairy cows to experimentally induced Escherichia coli mastitis. Six clinically healthy Holstein dairy cows received an intramammary inoculation of E. coli O111:K58 between 63 and 83 d(More)
INTRODUCTION To provide standard implemental cells for biomedical research, an immortalized mesenchymal stem cell (MSC) lineage was established from the bone marrow of Chinese Guizhou minipigs. We investigated the characteristics of the MSC transfected with hTERT. METHODS MSCs isolated from bone marrow (BM) were steadily transfected using a plasmid(More)
Pheromonicin-SA (Ph-SA) is a newly developed, engineered multidomain peptide that has a bactericidal effect against Staphylococcus aureus. The objective of this study was to characterize innate immune responses by Staph. aureus-stimulated bovine mammary epithelial cells (BMEC) following treatment with Ph-SA. Primary BMEC from one lactating Holstein cow were(More)
Anti-cancer agent adriamycin (ADR) has demonstrated high anti-tumor efficacy. However, its use in chemotherapy has been limited largely due to its diverse toxicities, including renal toxicity, such as nephrotic syndrome with proteinuria. Podocyte injury leads to glomeruli proteinuria. Wulingsan (WLS) is a blended traditional Chinese herbal medicine(More)
AIM To study the effects of praeruptorin C (pra-C), a pure constituent isolated from "Qian-Hu", the roots of Peucedanum praeruptorum Dunn. (Umbelliferae), on vascular hypertrophy, collagen content, transient [Ca2+]i, NO and vascular response of the thoracic aorta of renovascular and spontaneously hypertensive rats (RHR, SHR). METHODS RHR and SHR were(More)
The effects of praeruptorin C (Pra-C) on cardiac dysfunction, myocardial compliance, and collagen content in renovascular hypertensive rats have been studied. In rats with left ventricular hypertrophy (LVH), the ratio of cardiac flow (CF)/heart wet weight (HWW) and cardiac output (CO)/HWW decreased by 20.1% and 35.5%; LVSP and -dp/dtmax decreased by 19.4%(More)
