Article: Combination gene therapy using VEGF-shRNA and fusion suicide gene yCDglyTK inhibits gastric carcinoma growth.
[show abstract] [hide abstract]
ABSTRACT: Clinical trials of suicide gene therapy have achieved limited success, which suggests a need for improvement. Angiogenesis plays a crucial role in the progression of cancers, which is greatly regulated by vascular endothelial growth factor (VEGF).The current study was designed to evaluate the anti-tumor effects of VEGF siRNA in combination with fusion suicide gene yCDglyTK. Introduction of a VEGF-targeted small hairpin RNA (shVEGF) to CDTK/5-FC system could induce cell apoptosis more effectively and decrease micro vessel density in xenograft tissue, thus resulted in a significant tumor growth delay in SGC7901 xenografts. These findings for the first time suggest the potential of combination gene therapy using suicide gene therapy and anti-angiogenesis gene therapy.Experimental and Molecular Pathology 08/2011; 91(3):745-52. · 2.42 Impact Factor -
Article: Upregulation of soluble resistance-related calcium-binding protein (sorcin) in gastric cancer.
[show abstract] [hide abstract]
ABSTRACT: The aim of this paper was to identify novel proteins involved in the development of gastric cancer (GC). Isobaric tags for relative and absolute quantification (iTRAQ) analysis was adopted to separate the differentially expressed proteins between normal gastric epithelial cell line GES-1 and GC cell line SGC7901. Western blotting was utilized to validate the increased expression of sorcin in SGC7901; immunohistochemistry was performed to investigate its relationship with clinicopathological features of GC. Twelve differential proteins were identified. Seven proteins were found to be significantly upregulated (≥two-fold), while five proteins were markedly downregulated (≤0.5-fold), in SGC7901 cells. Sorcin was detected by this proteomic approach with a 5.4-fold upregulation in SGC7901. Western blotting and immunohistochemistry confirmed the overexpression of sorcin in GC. Immunohistochemistry showed us that sorcin was overexpressed in 55 samples of GC tissue (55/85, 64.71%) and was related closely to the depth of invasion, TNM stage, and lymph node metastasis of GC (P<0.05). The development of GC is regulated by multiple genes. Sorcin will be a novel molecular biomarker for the diagnosis, treatment, and prognosis of GC.Medical Oncology 11/2009; 27(4):1102-8. · 2.14 Impact Factor
