Deregulation of the pRB/E2F pathway, which occurs frequently in human malignancy, is often associated with inappropriate proliferation and/or apoptosis. While the role of E2F1 in apoptosis induction has been well-established, it remains unclear how this pro-apoptotic activity is regulated in cancer. Here we describe EZH2, an oncogenic polycomb histone(More)
UNLABELLED The limited spatial resolution of SPECT scanners does not allow an exact measurement of the local radiotracer concentration in brain tissue because partial-volume effects (PVEs) underestimate concentration in small structures of the brain. The aim of this study was to determine which brain structures show greater influence of PVEs in SPECT(More)
Doxorubicin is a chemotherapeutic drug widely used for the treatment of hepatocellular carcinoma but its efficacy is restricted by multidrug resistance. Non-steroidal anti-inflammatory drugs (NSAIDs) and cyclooxygenase (COX)-2-selective inhibitors exhibit anti-cancer properties as well as abilities to overcome drug resistance. In the present study,(More)
OBJECTIVE To observe the effects of high mobility group box 1 (HMGB1) protein on the release of cytokines of human umbilic vein endothelial cells (HUVECs) and the expression of interleukin-6 (IL-6) induced by lipopolysaccharide (LPS). METHODS HUVECs were cultured and then divided into the following groups. (1) Recombinant HMGB1 protein of the terminal(More)
Gastric cancer and liver cancer are among the most common malignancies and the leading causes of death worldwide, due to late detection and high recurrence rates. Today, these cancers have a heavy socioeconomic burden, for which a full understanding of their pathophysiological features is warranted to search for promising biomarkers and therapeutic targets.(More)
MicroRNAs (miRNAs) are small RNA molecules that regulate gene expression. Emerging evidence suggests that differential miRNA expression is associated with viral infection and tumorigenesis. Recently discovered microRNAs in the Marek's disease virus (MDV) genome have been suggested to have regulatory roles during MDV oncogenesis. To gain more insight into(More)
Viral infections usually result in alterations in the host cell proteome, which determine the fate of infected cells and the progress of pathogenesis. To uncover cellular protein responses in porcine reproductive and respiratory syndrome virus (PRRSV), infected pulmonary alveolar macrophages (PAMs) and Marc-145 cells were subjected to proteomic analysis(More)
Peroxisome proliferator-activated receptor-γ (PPAR-γ) ligands have been recently reported to have beneficial effects on organ fibrosis. However, their effects on extracellular matrix (ECM) turnover in hypertrophic scar fibroblasts (HSFs), and the related molecular mechanisms are unknown. HSFs were cultured and exposed to different concentration PPAR-γ(More)
Angiotensin II (Ang II) stimulation has been shown to regulate proliferation of skin fibroblasts and the production of extracellular matrix, which are very important processes in skin wound healing and fibrosis; however, there is little knowledge about the mechanisms involved in this process. We investigated the molecular aspects of this system with regards(More)
Normalization of the tumor vasculature is an emerging concept shown to improve anti-cancer therapy. However, there are currently no clinical interventions that effect long-lasting normalization. Here, we have developed a strategy for normalization by specific intratumoral delivery of LIGHT/TNFSF14. Importantly, normalization occurs by induced expression of(More)
