Short interspersed elements (SINEs) may be found in the genomes of a wide variety of mammals (Deininger and Batzer 1993). The Alu family of SINEs is one of the most successful mobile genetic elements, having arisen to a copy number in excess of 500,000 within the human genome in approximately 65 million years of primate evolution. Alu sequences are thought(More)
Newly isolated members of two recently propagated (young) Alu subfamilies were examined for sequence diversity and insertion polymorphism in primate genomes. The smaller subfamily (termed HS-2) is comprised of approximately 5 to 25 members, while the larger (termed Sb2) includes approximately 125 to 600 members. Individual members of these Alu subfamilies(More)
Full length Alu transcripts in HeLa cells are detected by primer extension using reverse transcriptase and are also analyzed as cloned cDNA sequences. The 5' end of these transcripts corresponds to the transcriptional start site for RNA polymerase III indicating that these RNAs are transcribed from their internal polymerase III promoters. The Alu(More)
A significant fraction of Alu repeats in human sperm DNA, previously found to be unmethylated, is nearly completely methylated in DNA from many somatic tissues. A similar fraction of unmethylated Alus is observed here in sperm DNA from rhesus monkey. However, Alus are almost completely methylated at the restriction sites tested in monkey follicular oocyte(More)
In anthropoid primates, cells in the magnocellular and parvocellular layers of the dorsal lateral geniculate nucleus (dLGN) are distinguished by unique retinal inputs, receptive field properties, and laminar terminations of their axons in visual cortex. To identify genes underlying these phenotypic differences, we screened RNA from magnocellular and(More)
Human Alu and adenovirus VA1 RNAs each stimulate the translational expression of reporter genes in co-transient transfection assays without affecting either the rate of global protein synthesis or the abundance of the reporter mRNA. This selective, post-transcriptional stimulation of expression, which is observed in human and mouse cell lines and for three(More)
Alu repeats in K562 cells are unusually hypomethylated and far more actively transcribed than those in other human cell lines and somatic tissues. Also, the level of Alu RNA in K562 cells is relatively insensitive to cell stresses, namely heat shock, adenovirus infection and treatment with cycloheximide, which increase the abundance of Alu RNA in HeLa and(More)
Mice lacking expression of the ß2 subunit of the neuronal nicotinic acetylcholine receptor (CHRNB2) display abnormal retinal waves and a dispersed projection of retinal ganglion cell (RGC) axons to their dorsal lateral geniculate nuclei (dLGNs). Transcriptomes of LGN tissue from two independently generated Chrnb2-/- mutants and from wildtype mice were(More)

Furthermore, this reduced ability to induce hsp70i protein was correlated with a significant increase in cell death after stress treatment (Fig. 3D), which indicates the critical importance of HSF2-mediated hsp70i bookmarking for cell stress survival. The results above show that in mitotic cells, HSF2 binds the hsp70i promoter, interacts with the CAP-G(More)
