Michael Levin is a Distinguished Professor in the Biology department at Tufts University. He holds the Vannevar Bush endowed Chair and serves as director of the Allen Discovery Center at Tufts and the Tufts Center for Regenerative and Developmental Biology. To explore the algorithms by which the biological world implemented complex adaptive behavior, he got dual B.S. degrees, in CS and in Biology and then received a PhD from Harvard University. He did post-doctoral training at Harvard Medical School, where he began to uncover a new bioelectric language by which cells coordinate their activity during embryogenesis. The Levin Lab works at the intersection of developmental biology, artificial life, bioengineering, synthetic morphology, and cognitive science.

Welcome to another exciting episode of our podcast series, where we dive deep into the world of science and innovation! In today’s episode, we have the privilege of interviewing Prof. Michael Levin, a renowned researcher in the fields of bioelectricity, regenerative biology, and biophysics.

Prof. Levin is the director of the Allen Discovery Center at Tufts University and has been making groundbreaking discoveries that are revolutionizing the field of regenerative medicine. His research focuses on understanding the electrical communication within and between cells, and how this communication can be harnessed for tissue repair and regeneration.

Being able to vocalize is one of the most essential elements of the human experience, with infants expected to start babbling their first words before they’re one year old, and much of their further life revolving around interacting with others using vocalizations involving varying degrees of vocabulary and fluency. This makes the impairment or loss of this ability difficult to devastating, as is the case with locked-in syndrome (LIS), amyotrophic lateral sclerosis (ALS) and similar conditions, where talking and vocalizing has or will become impossible.

In a number of concurrent studies, the use of a brain-computer interface (BCI) is investigated to help patients suffering from LIS (Sean L. Metzger et al., 2023) and ALS (Francis R. Willett et al., 2023) to regain their speaking voice. Using the surgically implanted microelectrode arrays (Utah arrays) electrical impulses pertaining to the patient’s muscles involved in speaking are recorded and mapped to phonemes, which are the elements that make up speech. Each of these phonemes requires a specific configuration of the muscles of the vocal tract (e.g. lips, tongue, jaw and larynx), which can be measured with a fair degree of accuracy.

In the case of the study by Sean L. Metzger et al. as recently published in Nature, the accompanying research article on the University of California San Francisco website details the story of their patient: Ann. At the age of 30, Ann suffered a brainstem stroke which rendered her essentially fully paralyzed. As an LIS patient she lacked for a long time even the ability to move her facial muscles.

In a recent study published in the Journal of Experimental Medicine, researchers investigated whether bone marrow-derived cells with heterozygous loss of Dnmt3a (Dnmt3a^+/Δ), the most common genetic alteration in clonal hematopoiesis (CH), contribute to colitis-associated colon cancer (CAC) pathogenesis.

An exciting new cancer drug has recently entered into a phase 1 clinical trial supported by promising pre-clinical work. The drug, named AOH1996, targets a protein called proliferating cell nuclear antigen (PCNA), an essential player in the biological processes of DNA replication and repair. A team of researchers from City of Hope published the data describing how they identified and characterized AOH1996 in Cell Chemical Biology last week. Since then, the news of AOH1996 has appeared prominently in both scientific and mainstream media.

Using a rational drug design approach that develops drugs based on their specific biological targets, the researchers identified AOH1996. Lead researcher Linda Malkas named the drug after Anna Oliva Healey, a girl born in 1996 who succumbed to neuroblastoma at age 9.

In the laboratory, the researchers tested AOH1996 on over 70 different kinds of tumor cells as well as some healthy control cells. While the drug killed the cancer cells, it notably does not affect non-cancer cells, including blood cells and the cells lining the airway. This indicates AOH1996 as a selective drug that will suppress tumor growth but likely not cause adverse effects that can occur when a cancer drug damages healthy cells.

Researchers demonstrated that the crosstalk between IL1RL1+ regulatory T-cells (Treg) and cancer-associated fibroblasts (CAFs) drives the tissue repairing.

Innovative technology that creates ultra-thin layers of human cells in tube-like structures could spur development of lifelike blood vessels and intestines in the lab.

The technique, known as RIFLE – rotational internal flow layer engineering – enables the construction of separate layers as delicate as one cell thick.

Such versatility is crucial to developing accurate human models of layered tubular tissue for use in research, offering an important alternative to animal models, experts say.
