Epidermal growth factor receptor (ErbB1, EGFR) is overexpressed in a variety of human cancer cells. It has been considered as a rational target for drug delivery. To identify novel ligands with specific binding capabilities to EGFR, we screened a phage display peptide library and found an enriched phage clone encoding the amino acid sequence YHWYGYTPQNVI(More)
Programmed cell death 1 (PD-1) is a key cell-surface receptor of CD28 superfamily that triggers inhibitory pathways to attenuate T-cell responses and promote T-cell tolerance. As a crucial role in tumor immunity, PD-1 has been a focus of studies in anti-cancer therapy. It has been approved that tumors could exploit PD-1-dependent immune suppression for(More)
BACKGROUND KH901 is a conditionally replicating oncolytic adenovirus, which reported selectively replicates in and lyses telomerase-positive tumor cells and expresses granulocyte macrophase colony-stimulating factor (GM-CSF). To determine the safety, feasibility and biological activity of KH901, a conditionally replicating oncolytic adenovirus, in patients(More)
PURPOSE The purpose of this study was to determine if a combination chemotherapy, using continuous intravenous infusion of fluorouracil (5-FU) in combination with split-dose cisplatin, in patients with recurrent or metastatic head and neck squamous-cell could improve previously reported clinical outcomes. METHODS Forty-two patients with recurrent or(More)
Current pemetrexed/platinum chemotherapy does not produce a satisfactory therapeutic response in advanced lung cancer patients. The aim of this study was to determine whether the administration of gefitinib, a tyrosine kinase inhibitor (TKI), intercalated with pemetrexed/platinum could improve the efficacy in chemotherapy-naïve patients with advanced(More)
BACKGROUND/AIMS There is no gold standard to treat primary gastric non-Hodgkin's lymphoma (PG-NHL). Hence, the establishment of effective prognostic factors of PG-NHL is essential for its staging and management. METHODOLOGY We retrospectively analyzed the clinicopathological features of PG-NHL patients who had been diagnosed from 1990 through 2008 in a(More)
PURPOSE To evaluate clinical outcomes after small incision lenticule extraction (SMILE) with different cap thicknesses in thick corneas. METHODS Forty patients with central corneal thickness of more than 560 μm were recruited in this prospective, randomized, masked, paired-eye study. Patients were randomized to receive SMILE with a 120-μm cap thickness in(More)
Squamous cell carcinoma is the main histological subtype of esophageal cancer in the east Asia. Oxaliplatin and fluorouracil are active agents for esophageal carcinoma. The aim of this phase II study was to evaluate the efficacy and safety of oxaliplatin, fluorouracil and leucovorin in patients with metastatic esophageal squamous cell carcinoma (ESCC).(More)
PURPOSE Celastrol, a traditional Chinese medicine, is widely used in anti-inflammation and anti-angiogenesis research. However, the poor water solubility of celastrol restricts its further application. This paper aims to study the effect of celastrol nanoparticles (CNPs) on corneal neovascularization (CNV) and determine the possible mechanism. METHODS To(More)
Tie2 is an endothelium-specific receptor tyrosine kinase known to play an important role in tumor angiogenesis. We sought to identify a small peptide ligand against Tie2 for developing a delivery targeting agent. We used hydrophobic analysis and comparative sequence/structure analysis to select a minimal peptide based on angiopoietin-2 amino acid sequence.(More)
