RNA blood levels of osteopontin splice variants are cancer markers
PURPOSE Despite a sizeable and continuously growing literature on osteopontin and cancer the molecule has not yet found entry into clinical diagnostics. Our identification of spliced variants that are more specific for cancer than the full-length transcript has opened new possibilities for reaching this goal. METHODS Here we have developed a real-time RT-PCR blood test and evaluated it in a p...
متن کاملOsteopontin Splice Variants Differentially Exert Clinicopathological Features and Biological Functions in Gastric Cancer
PURPOSE Gastric cancer (GC) remains a leading cause of death worldwide, and an elevated expression of osteopontin (OPN) may correlate with its poor survival. Alternative splicing of OPN can result in three isoforms, OPN-a, OPN-b and OPN-c. The aim of our current study is to examine the expression pattern and biological functions of OPN splice variants in GC. METHODS Firstly, we evaluated the ...
متن کاملCirculating Levels of sFlt1 Splice Variants as Predictive Markers for the Development of Preeclampsia
Angiogenic biomarkers, including soluble fms-like tyrosine kinase 1 (sFlt1), are thought to be predictors of preeclampsia onset; however, improvement is needed before a widespread diagnostic test can be utilized. Here we describe the development and use of diagnostic monoclonal antibodies specific to the two main splice variants of sFlt1, sFlt1-1 and sFlt1-14. These antibodies were selected for...
متن کاملOsteopontin splice variants differentially modulate the migratory activity of hepatocellular carcinoma cell lines.
Osteopontin (OPN, SPP1) is a secretory extracellular matrix protein that has been implicated in cancer-associated mechanisms such as metastasis, invasion and angiogenesis. Three OPN isoforms (OPN-a, -b and -c) derived from alternative splicing are known to exist, but their functional specificity remains unclear. Here, we found that the expression profile of OPN isoforms in hepatocellular carcin...
متن کاملSplice variants but not mutations of DNA polymerase beta are common in bladder cancer.
DNA polymerase beta (POLbeta) is a highly conserved protein that functions in base excision repair. Loss of the POLbeta locus on chromosome 8p is a frequent event in bladder cancer, and loss of POLbeta function could hinder DNA repair leading to a mutator phenotype. Both point mutations and large intragenic deletions of POLbeta have been reported from analysis of various tumor cDNAs but not fro...
