The biology of Kaposi sarcoma is poorly understood because the dominant cell type in Kaposi sarcoma lesions is not known. We show by gene expression microarrays that neoplastic cells of Kaposi sarcoma are closely related to lymphatic endothelial cells (LECs) and that Kaposi sarcoma herpesvirus (KSHV) infects both LECs and blood vascular endothelial cells(More)
The potential therapeutic value of resveratrol in age-related disease settings including cancer, diabetes, and Alzheimer's has emerged from a rapidly growing body of experimental evidence. Protection from oxidative stress appears to be a common feature of resveratrol that may be mediated through SirT1, though more specific molecular mechanisms by which(More)
Using a gene clustering strategy we determined intracellular pathway relationships within skeletal myotubes in response to an acute heat stress stimuli. Following heat shock, the transcriptome was analyzed by microarray in a temporal fashion to characterize the dynamic relationship of signaling pathways. Bioinformatics analyses exposed coordination of(More)
The cytoprotective stress response factor HSF1 regulates the transcription of the chaperone HSP70, which exhibits anti-inflammatory effects and improves insulin sensitivity. We tested the therapeutic potential of this pathway in rodent models of diabetes using pharmacological tools. Activation of the HSF1 pathway was achieved using potent inhibitors of the(More)
The tyrosine kinase inhibitor imatinib mesylate (Gleevec) has been demonstrated to protect various cell types from death by inhibition of Abelson tyrosine kinase (c-Abl). The aim of the present study was to establish whether imatinib protects the insulin producing beta-cell from the different apoptosis promoting agents in vitro and whether imatinib(More)
MicroRNAs (miRNAs) are deregulated in cancer and have been shown to exhibit both oncogenic and tumor suppressive functions. Although the functional effects of several miRNAs have been elucidated, those of many remain to be discovered. In silico analysis identified microRNA-206 (miR-206) binding sites in the 3'-untranslated regions (3'-UTR) of both the mouse(More)
Processed pseudogenes emerge by reverse transcription of spliced mRNAs followed by incorporation of the resultant cDNA into the genome. Their genesis requires that retrotransposition occurs within the germ line, a provision that significantly limits random distribution of source genes. We previously identified embryonic stem cell-specific genes as an(More)
