Herpes Viruses and Tumors Evolved to Learn How to Manipulate the Same Ancient RNA

Jan. 14, 2019 — Herpes viral infections use the ancient genetic material found in the human genome to proliferate, mimicking the same process tumors have been found to manipulate, Mount Sinai researchers have shown ... read more

DNA Tool Allows You to Trace Your Ancient Ancestry

Jan. 14, 2019 — Scientists at the University of Sheffield studying ancient DNA have created a tool allowing them to more accurately identify ancient Eurasian populations, which can be used to test an ... read more

Unraveling the Genetic Causes of Skin Cancer

Jan. 14, 2019 — Medical researchers are helping to identify the genetic factors that lead to squamous cell carcinoma. In a new article, they show how the interaction between a cell signaling pathway called MET and a ... read more

Gene-Editing Tool CRISPR Repurposed to Develop Better Antibiotics

Jan. 11, 2019 — Scientists have repurposed the gene-editing tool CRISPR to study which genes are targeted by particular antibiotics, providing clues on how to improve existing antibiotics or develop new ... read more

Researchers Correct Genetic Mutation That Causes IPEX, a Life-Threatening Autoimmune Syndrome

Jan. 10, 2019 — Researchers have created a method for modifying blood stem cells to reverse the genetic mutation that causes a life-threatening autoimmune syndrome called ... read more

Bacteria Help Discover Human Cancer-Causing Proteins

Jan. 10, 2019 — Researchers applied an unconventional approach that used bacteria to discover human proteins that can lead to DNA damage and promote ... read more

Jan. 10, 2019 — Researchers have found that the RNA-binding protein PUM2 contributes to the accumulation of defective mitochondria, a key feature of the aging process. Targeting PUM2 in old animals protects against ... read more

Using Genetics of Human Fat Cells to Predict Response to Anti-Diabetes Drugs

Jan. 10, 2019 — Researchers have demonstrated -- using fat cells derived from human stem cells -- that individual genetic variation can be used to predict whether the TZD rosiglitazone will produce the unwanted side ... read more

Study Suggests How to Treat Diastolic Heart Failure

Jan. 10, 2019 — New research uncovers what causes diastolic heart failure and how it can be ... read more

Uncovering More Options in Cancer Immunotherapy

Jan. 10, 2019 — If scientists want to boost immune cells' ability to kill cancer cells, then vast libraries of small molecules are potentially available. A new paper shows a platform to sort through them, plus ... read more

Jan. 10, 2019 — Scientists have created an 'on' switch for CRISPR-Cas9 that allows it to be turned on in select cells only, specifically those that have a particular protein-cutting enzyme, or protease. ... read more

CRISPR Study Reveals New Immune System Regulators

Jan. 10, 2019 — Scientists have created the first retroviral CRISPR-Cas9 gene editing library to explore the regulation of mouse T cells, which are key cells in the immune system. Researchers mapped the most ... read more

Jan. 10, 2019 — Distinguishing between left-handed and right-handed ('chiral') molecules is crucial in chemistry and the life sciences, and is commonly done using a method called circular dichroism. ... read more

Jan. 10, 2019 — Pairs of negatively charged phosphate groups and positive magnesium ions represent a key structural feature of DNA and RNA embedded in water. Vibrations of phosphate groups have now been established ... read more

Speeding Up Genetic Diagnosis of Huntington's Disease

Jan. 10, 2019 — Elongated segments of DNA cause Huntington's disease and certain other disorders of the brain. Researchers have developed a method to determine the length of the mutated genes quickly and ... read more

Jan. 10, 2019 — In a first for plant virology, a team from CIRAD recently used nanopore technology to sequence the entire genomes of two yam RNA viruses. This as yet little-used but promising molecular biology ... read more
