Artificial Life One Step Closer: Scientists Clone And Engineer Bacterial Genomes In Yeast And Transplant Genomes Back Into Bacterial Cells
August 21, 2009 — Scientists have developed new methods in which an entire bacterial genome was cloned in a yeast cell by adding yeast centromeric plasmid sequence to the bacterial chromosome and modified it in yeast ... > full story -
Epigenetics: Evolutionarily Preserved Mechanism Governs Use Of Genes
August 18, 2009 — Researchers have found that the protein coding parts of a gene are packed in special nucleosomes. The same type of packaging is found in the roundworm C. elegans, which is a primeval relative of ... > full story -
Scientists Take Early Steps Toward Mapping Epigenetic Variability
August 14, 2009 — Scientists have taken the first steps toward mapping epigenetic variability in cells and tissues. Mapping the human epigenome, similar to the human genome project in the 1990s, could someday allow ... > full story -
Silenced Genes As Warning Sign Of Blood Cancer
August 4, 2009 — In the genetic material of cancer cells, important growth inhibitors are often switched off by chemical labels in the DNA. How this happens has now been investigated. Scientists discovered in mice ... > full story -
Epigenetic Signature Changes In Low Oxygen Levels May Contribute To Prostate Cancer Development
July 30, 2009 — Researchers have characterized epigenetic signature changes in prostate cells under conditions of low oxygen levels that may lead to tumor development. The results of the study may provide important ... > full story -
Maternal, Paternal Genes' Tug-of-War May Last Well Into Childhood
July 28, 2009 — An analysis of rare genetic disorders in which children lack some genes from one parent suggests that maternal and paternal genes engage in a subtle tug-of-war well into childhood, and possibly as ... > full story -
Cancer's Distinctive Pattern Of Gene Expression Could Aid Early Screening And Prevention
July 27, 2009 — Distinctive patterns of genes turned off -- or left on -- in healthy versus cancerous cells could enable early screening for many common cancers and maybe help avoid them scientists ... > full story -
Nature Or Nurture? New Epigenetic Model Blurs Line In The Debate
July 21, 2009 — A new report complicates the debate over whether nature or nurture plays the most important role in complex diseases such as psychiatric disorders, heart disease and cancer. Scientists explain how ... > full story -
Re-Write The Textbooks: Key Genetic Phenomenon Shown To Be Different Than Believed
July 1, 2009 — Because females carry two copies of the X chromosome to males’ one X and one Y, they harbor a potentially toxic double dose of the over 1000 genes that reside on the X chromosome. To compensate ... > full story -
Novel Epigenetic Markers Of Melanoma May Herald New Treatments For Patients
June 29, 2009 — Melanoma is the most serious form of skin cancer, diagnosed in more than 50,000 new patients in the United States annually. As incidences continue to rise, the race is on to find the genetic and ... > full story
