Hepatic fibrosis is a common form of wound healing in response to chronic liver injuries and can lead to more serious complications, including mortality. It is well‑established that hepatic stellate cells (HSCs) are central mediators of hepatic fibrosis, and matrix metalloproteinase‑2 (MMP‑2) is important in the formation of liver fibrosis. In addition,(More)
BACKGROUND Targeted delivery is a promising strategy to improve the diagnostic imaging and therapeutic effect of cancers. In this paper, novel cetuximab (C225)-conjugated, gemcitabine (GEM)-containing magnetic albumin nanospheres (C225-GEM/MANs) were fabricated and applied as a theranostic nanocarrier to conduct simultaneous targeting, magnetic resonance(More)
BACKGROUND Gold nanoparticles (GNPs) can potentially be used in biomedical fields ranging from therapeutics to diagnostics, and their use will result in increased human exposure. Many studies have demonstrated that GNPs can be deposited in the kidneys, particularly in renal tubular epithelial cells. Chronic hypoxic is inevitable in chronic kidney diseases,(More)
Background and Aims: Hypoxia and oxidative stress contribute toward liver fibrosis. In this experiment, we used small hairpin RNA (shRNA) to interfere with the intracellular oxygen sensor-prolyl hydroxylase 1 (PHD1) and the intracellular oxidative stress sensor-kelch-like ECH associated protein 1 (Keap1) in the hypoxic hepatocytes in order to investigate(More)
Renal cell carcinoma (RCC) is characterized by excessive angiogenesis, while chronic kidney disease (CKD) suffers from the opposite problem-failure of reparative angiogenesis. It can be due to their different responses to hypoxic environment. But the specific molecular regulators are still unclear. This study is aimed to explore the influence of human renal(More)
Chronic hypoxia often occurs among patients with chronic kidney disease (CKD). Renal proximal tubular cells may be the primary target of a hypoxic insult. However, the underlying transcriptional mechanisms remain undefined. In this study, we revealed the global changes in gene expression in HK‑2 human renal proximal tubular cells under hypoxic and normoxic(More)
Circulating tumor cells (CTCs), isolated as a 'liquid biopsy', may provide important diagnostic and prognostic information. Therefore, rapid, reliable and unbiased detection of CTCs are required for routine clinical analyses. It was demonstrated that negative enrichment, an epithelial marker-independent technique for isolating CTCs, exhibits a better(More)
