Mapping transcriptomes;http://f1000.com/2136965?key=xj849p1lvpmyvk0 While mapping every transcriptional start site and operon of Helicobacter pylori at single-nucleotide resolution, the authors identify novel small RNAs, reveal the widespread nature of antisense transcription, and unveil a new technique to investigate the genomic complexities of other important pathogens, such as Salmonella and Mycobacterium tuberculosis. CM Sharma et al, linkurl:Nature,;http://www.ncbi.nlm.nih.gov/sites/entrez/20164839?dopt=Abstract&holding=f1000%2Cf1000m 464:250-5, 2010. Evaluated by N. Ahmed, Institute of Life Sciences, India; M.

linkurl:2. Epigenetics in mind;http://f1000.com/4303956?key=4djjldzr13n01dm The body's tendency to silence the expression of one parental allele in favor of the other -- a phenomenon known as genomic imprinting -- is much more widespread in the brain than scientists have believed, according to a new genome-wide study in mice. Surprisingly, more than 1300 genes expressed in the mouse brain appear to exhibit "parent-of-origin" epigenetic effects. C. Gregg, et al., linkurl:Science,;http://www.ncbi.nlm.nih.gov/sites/entrez/20616232?dopt=Abstract&holding=f1000%2Cf1000m 329:643-8, 2010. Evaluations by R. Sapolsky, Stanford University; ME Carter and L. de Lecea, Stanford University; J. Messing, Rutgers University; Y Ikeuchi and A Bonni, Harvard Medical School; D Sweatt, University of Alabama at Birmingham. linkurl:Free F1000 Evaluation;http://f1000.com/4303956?key=4djjldzr13n01dm linkurl:3. Translation goes local;http://f1000.com/3168959?key=0y2v7jkprk9bfyz Protein synthesis is a complicated game, but for the first time researchers have shown direct interaction between a transmembrane receptor, called DCC, and the translational machinery in rodent neurons, a step that likely facilitates localized protein production. J. Tcherkezian, et al., linkurl:Cell,;http://www.ncbi.nlm.nih.gov/sites/entrez/20434207?dopt=Abstract&holding=f1000%2Cf1000m 141:632-44, 2010. Evaluations by K Kwan and CB Chien, University of Utah; J Heraud and M Kiebler, Center for Brain Research, Medical University of Vienna, Austria; W Kroeze and B Roth, University of North Carolina; L Desgroseillers, University of Montreal, Canada; L Columbus, University of Virginia. linkurl:Free F1000 Evaluation;http://f1000.com/3168959?key=0y2v7jkprk9bfyz linkurl:4. No RNA "dark matter"?;http://f1000.com/3374960?key=b9ky6xh68fhgln7 Most of the DNA that's transcribed into RNA in fact codes for proteins, a finding that disputes previous studies that suggested that the majority of mammalian transcripts are non-coding "dark matter." H. van Bakel et al. linkurl:PLoS Biol,;http://www.ncbi.nlm.nih.gov/sites/entrez/20502517?dopt=Abstract&holding=f1000%2Cf1000m May; 8(5):e1000371, 2010.

Super E. Coli;http://f1000.com/3517956?key=19571mgrn0v6s9j The mother cell of E. coli maintains a constant growth rate throughout its replicative life (hundreds of cell divisions), despite accumulating damage and an increased probability of death, suggesting that growth and aging are decoupled, unlike all other studied aging models. P. Wang et al., linkurl:Curr Biol,;http://www.ncbi.nlm.nih.gov/sites/entrez/20537537?dopt=Abstract&holding=f1000%2Cf1000m 2010 May 26, 20:1099?1103.

How autophagosomes form;http://f1000.com/3425956?key=0x5ck35f5d8hsbj Under conditions of starvation, autophagosomes form to resupply the cell by bringing nutrients from the cytosol or other organelles to the lysosomes, ensuring the cell's survival. New findings reveal an essential ingredient to this mysterious process: the outer membrane of mitochondria. DW Hailey et al. linkurl:Cell,;http://www.ncbi.nlm.nih.gov/sites/entrez/20478256?dopt=Abstract&holding=f1000%2Cf1000m 141:656-67, 2010. Evaluated by R Gross, University of Wuerzburg, Germany; M Markaki and N Tavernarakis, Foundation for Research and Technology-Hellas, Greece; Y Xiang and Y Wang, University of Michigan, E Lau and Z Ronai, The Burnham Institute. linkurl:Free F1000 evaluation;http://f1000.com/3425956?key=0x5ck35f5d8hsbj linkurl:7. New tumor targets?;http://f1000.com/4759956?key=4491vf3hl9g0vnw A scan of 1800 megabases of DNA from 441 tumors reveals more than 2500 somatic mutations, providing the mutation "spectra" for cancers, including protein kinases and G-protein-coupled receptors, some of which may serve as druggable targets. Z. Kan et al, linkurl:Nature,;http://www.ncbi.nlm.nih.gov/sites/entrez/20668451?dopt=Abstract&holding=f1000%2Cf1000m 466:869-73, 2010.

Probing Human Genetic Diversity\n\n"1000 Genomes pilot a hit with geneticists"\nThe first stage of a project to probe human genetic diversity has found millions of new variations.\nhttp://www.sciencenews.org/view/generic/id/64761/title/1000_Genomes_pilot_a_hit_with_geneticists\n\nFor probing human DNA genetic diversity bear in mind that:\n\n"PERO SE MOVERA \nEARTH LIFE HAS ALWAYS BEEN AND STILL IS AN RNA WORLD"\nhttp://www.the-scientist.com/community/posts/list/320/122.page#6472\n\nA. Enzymes Exposed \nClearer views of the cell?s movers and shakers threaten a century-old mainstay of biology \nhttp://www.sciencenews.org/view/feature/id/60716/title/Enzymes_Exposed \n\nB. EHRC \nhttp://origins.swau.edu/q_and_a/life/questions/q3.html \n\nC. It's not the protein that makes the enzyme. It's the RNA that has evolved the protein. And it's the RNAs that have evolved and produce and employ the DNA templates to carry out their life processes, for enhancing Earth's biosphere, for enhancing and constraining as long as possible some of the energy destined to fuel the ongoing cosmic expansion. \n\nScience should adjust its vision, comprehension and conception. \n\nIT HAS ALWAYS BEEN AND IT STILL IS AN RNA EARTH LIFE. \n\n\nDov Henis \n(Comments From The 22nd Century) \nhttp://www.the-scientist.com/community/user/profile/1655.page\n\nSeed of Human-Chimp Genomes Diversity\nhttp://pulse.yahoo.com/_2SF3CJJM5OU6T27OC4MFQSDYEU/blog/articles/53079 \n03.2010 Updated Life Manifest \nhttp://www.the-scientist.com/community/posts/list/54.page#5065 \nCosmic Evolution Simplified \nhttp://www.the-scientist.com/community/posts/list/240/122.page#4427 \nGravity Is The Monotheism Of The Cosmos \nhttp://www.the-scientist.com/community/posts/list/260/122.page#4887 \nEvolution, Natural Selection, Derive From Cosmic Expansion\nhttp://darwiniana.com/2010/09/05/the-question-reductionists-fear/
