  • Interrupted reprogramming converts adult cells into high yields of progenitor-like cells
    on November 30, 2017 at 5:28 pm

    A modified version of iPS methodology, called interrupted reprogramming, allows for a highly controlled, safer, and more cost-effective strategy for generating progenitor-like cells from adult cells. Researchers converted adult mouse respiratory tract cells called Club cells into large, pure populations of induced progenitor-like cells, which retained a residual memory of their parental cell lineage. Moreover, these cells showed potential as a cell replacement therapy in mice with cystic fibrosis. […]

  • New procedures for DNA stability
    on November 16, 2017 at 3:50 pm

    In eukaryotic cells the proximity of the genes to the nuclear pores, which are found in the nuclear membrane, contributes to maintaining the integrity of the genome. This is due to the fact that the anchoring of DNA to the pore during transcription avoids the formation of DNA-RNA hybrids, which are a natural source of DNA breaks and genome instability. […]

  • How the skin becomes inflamed: Toxin-producing bacteria
    on November 8, 2017 at 5:42 pm

    Researchers report the discovery of a key underlying immune mechanism that explains why to how our skin becomes inflamed from conditions such as atopic dermatitis, more commonly known as eczema. Toxin-producing bacteria on the surface of our skin induces a protein that causes our own cells to react and cause inflammation. […]

  • Elucidation of bone regeneration mechanism
    on November 3, 2017 at 12:53 pm

  • New way to prevent genetically engineered and unaltered organisms from producing offspring
    on October 12, 2017 at 1:10 pm

    A major obstacle to applying genetic engineering to benefit humans and the environment is the risk that organisms whose genes have been altered might produce offspring with their natural counterparts, releasing the novel genes into the wild. Now, researchers have developed a promising way to prevent such interbreeding. The approach, called 'synthetic incompatibility,' effectively makes engineered organisms a separate species unable to produce viable offspring with their wild or domesticated relatives. […]

  • GM soybean oil causes less obesity and insulin resistance but is harmful to liver function
    on October 2, 2017 at 12:48 pm

    Researchers have tested a genetically-modified soybean oil used in restaurants and found that while it induces less obesity and insulin resistance than conventional soybean oil, its effects on diabetes and fatty liver are similar to those of conventional soybean oil, the major vegetable cooking oil used in the United States, with popularity on the increase worldwide. The study also compares the GM soybean oil to coconut and olive oils. […]
