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.

Scientists craft a protein-based bandpass filter for synthetic biology

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

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.

Building An Expert GPT in Physics-Informed Neural Networks, with GPTs

Posted by in categories: bioengineering, robotics/AI

One of the most interesting releases in the recent OpenAI’s DevDay is the GPTs. Essentially, GPTs are custom versions of ChatGPT that anyone can create for specific purposes. The process of configuring a workable GPT involves no coding but purely through chatting. As a result, since the release, a diverse of GPTs have been created by the community to help users be more productive and create more fun in life.

As a practitioner in the domain of physics-informed neural networks (PINN), I use ChatGPT (GPT-4) a lot to help me understand complex technical concepts, debug issues encountered when implementing the model, and suggest novel research ideas or engineering solutions. Despite being quite useful, I often find ChatGPT struggles to give me tailored answers beyond its general knowledge of PINN. Although I can tweak my prompts to incorporate more contextual information, it is a rather time-consuming practice, and can quickly deplete my patience sometimes.

Now with the possibility of easily customizing ChatGPT, a thought occurred to me: why not develop a customized GPT that acts as a PINN expert 🦸‍♀️, draws knowledge from my curated sources, and strives to answer my queries about PINN in a tailored way?

Gene editing stocks mixed despite world’s first CRISPR drug

Posted by in categories: bioengineering, biotech/medical

There were mixed reactions across gene editing space on Thursday after CRISPR Therapeutics (NASDAQ: CRSP) and Vertex Pharmaceuticals (NASDAQ: VRTX), in a world’s first, won U.K. approval for their CRISPR-based drug exa-cel for sickle cell disease and beta-thalassemia.

CRISPR Therapeutics (CRSP) has added ~5%, and MaxCyte (NASDAQ: MXCT), which has a licensing deal with the Swiss biotech, has gained ~4%. Vertex Pharma (VRTX) is trading lower for the third straight session.

Other CRSPR-based drug developers Graphite Bio (GRPH) and Precision BioSciences (DTIL) are also among the gainers, while notable gene editing biotechs Editas Medicine (EDIT), Beam Therapeutics (BEAM), Intellia Therapeutics (NTLA), and Verve Therapeutics (VRTX) are in the red.

‘Neural networks today are about as similar to a brain as an airplane is to a bird.’ — Kwabena Boahen, PhD, professor of bioengineering and of electrical engineering One problem, as Boahen sees it, is that AI relies on a “synaptocentric” mode of computing, in that half of the nodes — lines of binary…

The world’s first gene therapy for sickle cell disease has been approved in Britain

Posted by in categories: bioengineering, biotech/medical

LONDON (AP) — Britain’s medicines regulator has authorized the world’s first gene therapy treatment for sickle cell disease, in a move that could offer relief to thousands of people with the crippling disease in the U.K. In a statement Thursday, the Medicines and Healthcare Regulatory Agency said it approved Casgevy, the first medicine licensed using the gene editing tool CRISPR, which won its makers a Nobel prize in 2020. The agency approved…

U.K. Greenlights World’s First Crispr Gene Editing Therapy

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

The one-time treatment helped relieve symptoms of disease and could free patients from the need for bone marrow transplants or regular blood transfusions, Beach said, adding that the drug hopefully offers a permanent fix for the condition.

The MHRA said it identified no significant safety concerns during the trials and will continue to closely monitor Casgevy’s safety after approval.

Vertex CEO and President Reshma Kewalramanit celebrated Casgevy’s approval as “a historic day in science and medicine” and Samarth Kulkarni, CEO and Chairman of Crispr Therapeutics, said it will hopefully mark “the first of many applications of this Nobel Prize winning technology to benefit eligible patients with serious diseases.” The two companies are hoping for similarly positive decisions from the MHRA’s counterparts in the Europe Union and the U.S., which are in the process of evaluating Casgevy, also known as exa-cel. The Food and Drug Administration is expected to make a decision in early December and has a deadline of December 8. The agency appears poised to follow the MHRA and approve the treatment, with its advisors confident of the drug’s efficacy and benefit but wary of theoretical unintended consequences of genetic modifications.

Drug-Activated Protein Boosts Memory

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

Summary: Researchers made a breakthrough in memory research by genetically modifying the LIMK1 protein, crucial for memory, to be controlled by the drug rapamycin.

This study demonstrates the ability to enhance memory functions by manipulating synaptic plasticity in the brain.

The engineered protein showed significant memory improvement in animal models with age-related cognitive decline, offering potential for innovative treatments for neuropsychiatric diseases like dementia. This ‘chemogenetic’ approach, blending genetics and chemistry, opens new avenues in neurological research and therapy.
