Genomics will change what patients expect from their provider, as well as change how physicians treat them. Before this happens, education on both sides is needed. This month we look at some of the big talking points.

New Approaches to the Old Hunt for NASH Therapies

Non-Alcoholic Steatohepatitis (NASH) is the most severe form of non-alcoholic fatty liver disease (NAFLD). The global prevalence of NAFLD is as high as one billion and is the most common cause of chronic liver disease, affecting between 80 and 100 million in the U.S., among whom nearly 25% progress to NASH. NASH is characterized by […]

US Government Restricts Research on Foetal Tissue

The US government has ended medical research funding for scientists using foetal tissue, and cancelled a multi million-dollar contract for a laboratory at the University of California at San Francisco, which required the material to test new HIV therapies. According to a White House spokesperson, the decision was taken by President Trump himself.

Stem Cells Edited In Vivo For the First Time

Researchers have genetically modified stem cells inside the bodies of mice for the first time, in a study that could lead eventually to new potential for stem cell therapies. The study also shows potential for studying genetically-edited stem cells within the body, rather than in the lab.

CRISPR Twins’ Lives Could Be Shortened by Two Years

He Jiankui, the Chinese scientist who created the first gene-edited twin children last year, could have unknowingly shortened their lives by more than 1.9 years. A study into the DNA and death records of 400,000 volunteers in the UK Biobank found the genetic mutations to gene CCR5 were “of quite strong effect.”

Fungus Genetically Modified to Wipe Out Malaria-Carrying Mosquitoes

University of Maryland scientists have genetically modified a fungus to produce a toxin fatal to mosquitoes, in order to reduce the malaria death toll they currently cause. An out-of-lab trial destroyed a mosquito population almost entirely within 45 days, leading some to criticise the work as “too dangerous” for the real world.

Autism-Causing Variations Found in “Junk” DNA

Princeton University researchers have used AI techniques to uncover junk DNA mutations which can lead to autism. The findings are the first to link functionally link mutations in regulatory DNA with a disease like autism, and possibly prove that the changes affect how genes are expressed in the brain.

First Lifeform Created with Fully Redesigned DNA

Cambridge University scientists have created the first living organism with fully synthetic DNA radically altered from its original state. The strain of E coli was given a smaller set of genetic instructions than its counterparts, proving life can continue with such a restricted code.

Unlocking the Promise of DNA Sequencers: An Interview with Ben Langmead

Dr Ben Langmead is a computational biologist and assistant professor in the Computer Science Department at Johns Hopkins University, most famous for his creation of the Bowtie and Bowtie 2 sequence alignment algorithms, used to improve sequencing alignment quality. FLG spoke to Dr Langmead about his lab, his recent work using the Stampede2 supercomputer cluster to optimise sequencing data analysis software, and the future for DNA sequencers as a whole.

Researchers Identify Potential New Metastasis Biomarker

Yale University researchers have discovered a potential new biomarker for identifying individuals with increased risk of prostate cancer metastasis. The findings announced that mitochondrial protein syntaphilin is vital in determining the balance between tumour cell proliferation and tumour cell invasion, and is expressed significantly at the invasive tumour edge in prostate cancer.

Gene Therapy Could Heal Cells After Heart Attack

Gene therapy can make heart cells regenerate after a heart attack, King’s College London researchers have found. The study, published in Nature, stated that a small piece of genetic material called microRNA-199 delivered into a pig’s heart after myocardial infarction resulted in almost total cardiac recovery a month later.
