by Dr Steven Magennis, University of Glasgow Credit: Pixabay/CC0 Public Domain New research on the structure and dynamics of a branched form of DNA called a three-way junction could lead to more effectively targeted treatments for degenerative disorders like Huntington’s Disease, scientists say. In a new paper published in the journal Nature Communications, chemists from the University of Glasgow...
‘Invisible’ stem cells evade natural killer cells using immune ‘off-switch’
by University of California, San Francisco Credit: CC0 Public Domain UC San Francisco scientists have discovered a new way to control the immune system’s ‘natural killer’ (NK) cells, a finding with implications for novel cell therapies and tissue implants that can evade immune rejection. The findings could also be used to enhance the ability of cancer...
RNA molecules are masters of their own destiny
Research suggests the products of transcription — RNA molecules — regulate their own production through a feedback loop. At any given moment in the human body, in about 30 trillion cells, DNA is being “read” into molecules of messenger RNA, the intermediary step between DNA and proteins, in a process called transcription. Scientists have a pretty...

Study reveals how one antibody blocks dangerous effects of dengue virus infection, offering potential path to prevention
by University of Michigan Researchers have revealed how one antibody (in green) is able to neutralize a protein that is central to the dengue virus’s ability to cause disease, by blocking the protein’s ability to interact with host cells. Credit: Rajani Arora, U-M Life Sciences Institute A team of researchers has discovered an antibody that blocks the ability of...
Protein that can be toxic in the heart and nerves may help prevent Alzheimer’s
UT SOUTHWESTERN MEDICAL CENTER IMAGE: Abnormal deposits of the protein amyloid beta in the brain have been linked to Alzheimer’s disease. The above illustration reveals a potential way discovered by UTSW researchers to stop this process, leveraging the protective nature of the protein transthyretin (TTR) to identify a segment of this protein, TTR-S, that halts...
Mediterranean diet may decrease risk of prostate cancer progression
UNIVERSITY OF TEXAS M. D. ANDERSON CANCER CENTER In a study to examine a Mediterranean diet in relation to prostate cancer progression in men on active surveillance, researchers from The University of Texas MD Anderson Cancer Center found that men with localized prostate cancer who reported a baseline dietary pattern that more closely follows the key principles...
