Mouse Study Reveals How to Help Speed Up The Liver’s Self-Regeneration Process

Posted by in category: biotech/medical

The liver is known for its ability to regenerate. It can completely regrow itself even after two-thirds of its mass has been surgically removed. But damage from medications, alcohol abuse, or obesity can eventually cause the liver to fail.

Currently, the only effective treatment for end-stage liver disease is transplantation.

However, there is a dearth of organs available for transplantation. Patients may have to wait from 30 days to over 5 years to receive a liver for transplant in the US. Of the over 11,600 patients on the waiting list to receive a liver transplant in 2021, only a little over 9,200 received one.

“This data set—and the opportunities it creates—are … arguably one of the most important things to have happened in neurobiology recently,” says Rachel Wilson, a neurobiologist at Harvard University who was not involved in the new work. “Anyone in the world who is interested can download the data set and determine whether any two neurons … talk to each other.”

Cutting-Edge Cancer Treatments: Advancing Genomic Medicine — Medical Frontiers-JAPAN Live & Programs

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

Genomic medicine is undergoing rapid change after the Japanese public health insurance system began to cover genetic testing in 2019. Cancer patients who meet certain criteria are able to take these tests for a relatively affordable price, and their genetic information is collected in a massive database and analyzed with the help of around 170 hospitals across the country. But challenges remain, with suitable drugs available for only 10% of patients who undergo testing.

Quantum effects help make DNA unstable

Posted by in categories: biotech/medical, genetics, quantum physics

Quantum effects play a hitherto unexpected role in creating instabilities in DNA – the so-called “molecule of life” that provides instructions for cellular processes in all living organisms. This conclusion, based on work by researchers at the University of Surrey in the UK, goes against long-held beliefs that quantum behaviour is not relevant in the wet, warm environment of cells, and could have far-reaching consequences for models of genetic mutation.

The two strands of the DNA double helix are linked together by hydrogen bonds between the DNA bases. There are typically four different bases, called Guanine (G), Cytosine ©, Adenine (A) and Thymine (T). In the standard configuration, A always bonds to T while C always bonds to G. However, if the protons (nuclei of the hydrogen atoms) that make up the bonds hop from one strand of DNA to the other then a genetic mutation can occur.

Researchers explore single-cell sequencing technologies to understand molecular mechanisms of autoimmune diseases

Posted by in category: biotech/medical

A recent review published in the Journal of Autoimmunity discussed the applications of single-cell ribonucleic acid sequencing (scRNA-seq) in understanding autoimmune disorders.

The review comprehensively covered the principles, procedures, and sequencing platforms used in scRNA-seq, and explored its use in understanding the mechanisms of nine systemic and 32 organ-specific autoimmune and autoinflammatory diseases.

Autoimmune diseases (AID) are a complex phenomenon involving various types of cells. The diseases occur when the body’s immune system fails to recognize its cells and components and launches an immune response against them. Autoimmune diseases are broadly divided into organ-specific and non-organ-specific AID.

Michael Levin: Intelligence Beyond the Brain

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

*Intelligence Beyond the Brain: morphogenesis as an example of the scaling of basal cognition*

*Description:*
Each of us takes the remarkable journey from physics to mind: we start life as a quiescent oocyte (collection of chemical reactions) and slowly change and acquire an advanced, centralized mind. How does unified complex cognition emerge from the collective intelligence of cells? In this talk, I will use morphogenesis to illustrate how evolution scales cognition across problem spaces. Embryos and regenerating organs produce very complex, robust anatomical structures and stop growth and remodeling when those structures are complete. One of the most remarkable things about morphogenesis is that it is not simply a feed-forward emergent process, but one that has massive plasticity: even when disrupted by manipulations such as damage or changing the sizes of cells, the system often manages to achieve its morphogenetic goal. How do cell collectives know what to build and when to stop? Constructing and repairing anatomies in novel circumstances is a remarkable example of the collective intelligence of a biological swarm. I propose that a multi-scale competency architecture is how evolution exploits physics to achieve robust machines that solve novel problems. I will describe what is known about developmental bioelectricity — a precursor to neurobiology which is used for cognitive binding in biological collectives, that scales their intelligence and the size of the goals they can pursue. I will also discuss the cognitive light cone model, and conclude with examples of synthetic living machines — a new biorobotics platform that uses some of these ideas to build novel primitive intelligences. I will end by speculating about ethics, engineering, and life in a future that integrates deeply across biological and synthetic agents.

The Switch to Regenerative Medicine

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

As the 3rd presenter during the morning session of the American Society for Dermatologic Surgery Meeting, “Emerging Concepts,” Saranya Wyles, MD, PhD, assistant professor of dermatology, pharmacology, and regenerative medicine in the department of dermatology at the Mayo Clinic in Rochester, Minnesota, explored the hallmarks of skin aging, the root cause of aging and why it occurs, and regenerative medicine. Wyles first began with an explanation of how health care is evolving. In 21st-century health care, there has been a shift in how medical professionals think about medicine. Traditionally, the first approach was to fight diseases, such as cancer, inflammatory conditions, or autoimmune disorders. Now, the thought process is changing to a root cause approach with a curative option and how to rebuild health. Considering how to overcome the sequence of the different medications and treatments given to patients is rooted in regenerative medicine principles.

For skin aging, there is a molecular ‘clock’ that bodies follow. Within the clock are periods of genomic instability, telomere attrition, and epigenetic alterations, and Wyles’ lab focuses on cellular senescence.

“We’ve heard a lot at this conference about bio stimulators, aesthetics, and how we can stimulate our internal mechanisms of regeneration. Now, the opposite force of regeneration is the inhibitory aging hallmarks which include cellular senescence. So, what is cell senescence? This is a state that the cell goes into, similar to apoptosis or proliferation, where the cell goes into a cell cycle arrest so instead of dividing apoptosis, leading to cell death, the cell stays in this zombie state,” said Wyles.

Lessons from COVID vaccine development and approval can aid the process.

According to Uğur Şahin and Özlem Türeci, the founders of the German company BioNTech, mRNA vaccines that can help target cancer could be ready for use before the end of this decade, The Guardian.
