The 70% (or 2/3) partial hepatectomy (PHx) rat liver model provides an effective medium for study of the transition and regulation of hepatocytes from quiescent to proliferating phase. Although the gene expression pattern has come under intense scrutiny, a differential proteomic study could help to reveal the mechanism of how the process is initiated and(More)
The development of metastasis is the leading cause of death and an enormous therapeutic challenge in cases of non-small cell lung cancer. To better understand the molecular mechanisms underlying the metastasis process and to discover novel potential clinical markers for non-small cell lung cancer, comparative proteomic analysis of two non-small cell lung(More)
A new constitutive centromere-specific protein (CENP) has been identified as a result of its recognition as an autoantigen by serum from a patient with gastric antral vascular ectasia disease. Conventional immunoblotting and two-dimensional double blotting with both this antiserum and a known anti-centromere antiserum showed that this antiserum(More)
Lung cancer is at present the number one cause of cancer death and no biomarker is available to detect early lung cancer in serum samples so far. The objective of this study is to find specific biomarkers for detection of lung cancer using Surface Enhanced Laser Desorption/Ionization (SELDI) technology. In this study, serum samples from 30 lung cancer(More)
Laryngeal carcinoma is the most common malignancy among head and neck tumors. The purpose of this study is to find biomarkers for laryngeal carcinoma in patient blood serum using the Surface Enhanced Laser Desorption/Ionization (SELDI) technique. Serum samples from 33 laryngeal carcinoma (12 cases of glottis, 18 of supraglottis and 3 of subglottis) patients(More)
Tumorigenesis is caused by an uncontrolled cell cycle and the altered expression of many genes. Here, we report a gene CREPT that is preferentially expressed in diverse human tumors. Overexpression of CREPT accelerates tumor growth, whereas depletion of CREPT demonstrates a reversed effect. CREPT regulates cyclin D1 expression by binding to its promoter,(More)
PURPOSE Cancer-testis (CT) antigens are often expressed in a proportion of tumors of various types. Their restricted normal tissue expression and immunogenicity make them potential targets for immunotherapy. CABYR is a calcium-binding tyrosine phosphorylation-regulated fibrous sheath protein initially reported to be testis specific and subsequently shown to(More)
S100A11, one secreted protein, is overexpressed in certain cancers. We investigated S100A11 expression in various subtypes of lung cancer and explored its role in cell proliferation. S100A11 mRNA level was examined in 45 pairs of frozen lung cancer tissues by reverse transcriptase PCR (RT-PCR). The specific expression and subcellular distribution of S100A11(More)
BACKGROUND Cholangiocarcinoma (CC) is devastating neoplasm and very few specific biomarkers could be used in clinical diagnosis. A study was taken to find novel serum biomarkers for CC. METHODS Surface enhanced laser desorption/ionization (SELDI) technology was used to analyze 427 serum samples including 56 CCs, 49 hepatobiliary diseases, 269 other cancer(More)
Protein tyrosine phosphatase-like A (PTPLa) has been implicated in skeletal myogenesis and cardiogenesis. Mutations in PTPLa correlated with arrhythmogenic right ventricular dysplasia in humans and congenital centronuclear myopathy with severe hypotonia in dogs. The molecular mechanisms of PTPLa in myogenesis are unknown. In this report, we demonstrate that(More)
