BACKGROUND The interrogation of proteomes ("proteomics") in a highly multiplexed and efficient manner remains a coveted and challenging goal in biology and medicine. METHODOLOGY/PRINCIPAL FINDINGS We present a new aptamer-based proteomic technology for biomarker discovery capable of simultaneously measuring thousands of proteins from small sample volumes(More)
The available evidence suggests that during the process of formation of a functional or "open" complex at a promoter, Escherichia coli RNA polymerase transiently realigns the two contacted regions of the promoter, thus stressing the intervening spacer DNA. We tested the possibility that this process plays an active role in the formation of an open complex.(More)
BACKGROUND Malignant pleural mesothelioma (MM) is an aggressive, asbestos-related pulmonary cancer that is increasing in incidence. Because diagnosis is difficult and the disease is relatively rare, most patients present at a clinically advanced stage where possibility of cure is minimal. To improve surveillance and detection of MM in the high-risk(More)
We have used block substitution mutagenesis and in vitro transcription to define sequence elements important for efficient initiation and 3' end-formation of the trans-spliced leader RNA (SL RNA) of the parasitic nematode Ascaris lumbricoides. These experiments indicate that the SL RNA has an unusual promoter structure containing elements which include the(More)
Lung cancer remains the most common cause of cancer-related mortality. We applied a highly multiplexed proteomic technology (SOMAscan) to compare protein expression signatures of non small-cell lung cancer (NSCLC) tissues with healthy adjacent and distant tissues from surgical resections. In this first report of SOMAscan applied to tissues, we highlight 36(More)
