Patient Dies After Being Gene-Edited to Have Lower Cholesterol

Posted by in categories: bioengineering, biotech/medical, genetics

Researchers have been able to reduce dramatically the level of bad cholesterol in human subjects after injecting them with an experimental gene editing treatment, according to the science journal Nature, which is the first time this technique, called base editing, has been done on humans.

But at least one person died after receiving an infusion, prompting a round of safety concerns.

In the clinical trial, 10 subjects with congenitally high levels of bad cholesterol, aka low-density lipoprotein (LDL), were given an injection of VERVE-101, a gene-editing treatment that uses the base editing technique. This treatment then turned off the gene for the protein PCSK9, which is found in the liver and regulates LDL. High levels of LDL can lead to coronary heart disease.

Gene editing will change medicine—and maybe health investing too

Posted by in categories: bioengineering, biotech/medical, chemistry, genetics, health

The groundbreaking gene-editing technology known as Crispr, which acts like a molecular pair of scissors that can be used to cut and modify a DNA sequence, has moved rather quickly from the pages of scientific journals to the medical setting. Earlier this month, about three years after Jennifer Doudna and Emmanuelle Charpentier won the Nobel Prize in Chemistry for describing how bacteria’s immune system could be used as a tool to edit genes, regulators in the U.K. approved the first Crispr-based treatment for sickle cell disease and beta-thalassemia patients. The treatment, from Vertex Pharmaceuticals and Crispr Therapeutics, could be approved by the U.S. Food and Drug Administration early next month for sickle cell patients.

While many obstacles lie ahead for the nascent field, such as how to pay for treatments that typically cost more than $1 million, these regulatory approvals are just the start as newer gene-editing technologies such as base and prime editing make their way through human studies. In an interview, Prof. Doudna says the approval is “a turning point in medicine because it really shows how genome editing can be used as a one-and-done cure for disease.”

Gene editing is part of a broader therapeutic revolution that encompasses genetic and cellular medicine. The pills and injections we are all familiar with generally target proteins or pathways in the body to treat disease. With gene and cell therapy, we can now target the root cause of disease, sometimes curing patients.

Welcome to the Brave New World of CRISPR Gene Editing

Posted by in categories: bioengineering, biotech/medical, chemistry, genetics

Cell toxicity and genomic instability are potential side effects from the use of CRISPR-Cas9. The gene editing tool can also cause large rearrangements of DNA through retrotransposition to theoretically trigger tumor development.

While rare, the fact that CRISPR is used to edit millions of cells for some therapies means precautionary steps are warranted given the potential increase in cancer risk. However, retrotransposition is much rarer during base editing, a more precise technique that chemically changes just one “letter” of the genetic code without causing a double-strand break in DNA.

Although MHRA decided that the benefits of Casgevy outweigh its risks, the U.K. regulator granted a one-year conditional marketing authorization of the world-first gene therapy based on the findings of two global clinical trials, noting that no significant safety concerns were identified during the trials.

PhD student engineers potato plant that sniffs out nuclear radiations

Posted by in categories: bioengineering, electronics

The bioengineered potato plant provides a reliable indicator of potentially hazardous radiation levels without requiring complicated sensor machines or monitoring methods.


Referred to as a phytosensor, it is a type of sensor or detector that detects certain compounds or environmental conditions by using plants (phyto-meaning plant).

Networking nano-biosensors for wireless communication in the blood

Posted by in categories: bioengineering, biotech/medical, health, internet, nanotechnology, robotics/AI

Biological computing machines, such as micro and nano-implants that can collect important information inside the human body, are transforming medicine. Yet, networking them for communication has proven challenging. Now, a global team, including EPFL researchers, has developed a protocol that enables a molecular network with multiple transmitters.

First, there was the Internet of Things (IoT) and now, at the interface of computer science and biology, the Internet of Bio-Nano Things (IoBNT) promises to revolutionize medicine and health care. The IoBNT refers to biosensors that collect and , nano-scale Labs-on-a-Chip that run medical tests inside the body, the use of bacteria to design biological nano-machines that can detect pathogens, and nano-robots that swim through the bloodstream to perform targeted drug delivery and treatment.

“Overall, this is a very, very exciting research field,” explained Assistant Professor Haitham Al Hassanieh, head of the Laboratory of Sensing and Networking Systems in EPFL’s School of Computer and Communication Sciences (IC). “With advances in bio-engineering, , and nanotechnology, the idea is that nano-biosensors will revolutionize medicine because they can reach places and do things that current devices or larger implants can’t,” he continued.

Team Creates Synthetic Enzymes to Unravel Molecular Mysteries

Posted by in categories: bioengineering, biotech/medical

A University of Texas at Dallas bioengineer has developed synthetic enzymes that can control the behavior of the signaling protein Vg1, which plays a key role in the development of muscle, bone and blood in vertebrate embryos.

The team of researchers is using a new approach, called the Synthetic Processing (SynPro) system, in zebrafish to study how Vg1 is formed. By learning the molecular rules of signal formation in a developing animal, researchers aim to engineer mechanisms – such as giving cells new instructions – that could play a role in treating or preventing disease.

Dr. P.C. Dave P. Dingal, assistant professor of bioengineering in the Erik Jonsson School of Engineering and Computer Science, and his colleagues published their research online Oct. 16 in Proceedings of the National Academy of Sciences.

EPFL scientists have crafted a biological system that mimics an electronic bandpass filter, a novel sensor that could revolutionize self-regulated biological mechanisms in synthetic biology.

Synthetic biology holds the promise of enhancing and modifying into innumerable new technologies for the benefit of society. This engineering approach to biology has already reaped benefits in the fields of drug delivery, agriculture, and energy production.

In a paper published in Nature Chemical Biology, EPFL researchers at the Laboratory of Protein Design and Immunoengineering (LPDI) at the School of Engineering have taken an important step in designing more performative biological systems.
