Tohoku University researchers have developed a strategy that could help cells get rid of disease-related debris. Further research could lead to treatments for neurodegenerative and metabolic diseases, Down syndrome, and maybe even aging-related diseases. The findings were published in the journal Molecular Cell.

Cells have a natural ability to routinely rid themselves of unnecessary or dysfunctional proteins and organelles. During this process of “autophagy,” debris are tagged with a compound called ubiquitin and then degraded within tiny cellular vacuoles. Autophagy is impaired in some cancers, and neurodegenerative and metabolic diseases, so scientists have been working to develop drugs that can regulate this process. However, little is known about the details of autophagy, such as how the cell knows which components to tag with ubiquitin.

In previous research, Hirokazu Arimoto, a chemical biologist at Tohoku University, and colleagues found that autophagy is initiated against invading streptococci bacteria when they are tagged with the nucleic acid guanine. The researchers wondered if guanine tagging could also initiate autophagy against other cellular components.

Recently, Libella Gene Therapeutics has announced that it will be running a patient-paid trial in Colombia with an eye-watering $1 million USD price tag on enrollment.

Patient-paid trial likely to cause backlash

The topic of patient-paid trials often stirs up considerable debate among the research community, regulatory authorities, and the general public, with many people suggesting that it is unethical to expect patients to pay to participate in clinical trials. While this is a controversial issue, these trials are a legitimate way to test therapies that would otherwise struggle to reach the clinic due to cost constraints, and the data gathered by such trials can still be valuable.

The study saw the deployment of a multiple target gene therapy focused on 3 known longevity genes delivered via an adeno-associated virus. The focus was on mitigating T2 diabetes, heart failure, and kidney failure in mouse models with very positive results observed.

MANHATTAN, Kan., Nov. 21, 2019 /PRNewswire/ — Libella Gene Therapeutics, LLC (“Libella”) announces an institutional review board (IRB)-approved pay-to-play clinical trial in Colombia ( South America ) using gene therapy that aims to treat and ultimately cure aging. This could lead to Libella offering the world’s only treatment to cure and reverse aging by 20 years.

Chemotherapy-treated cancer cells that enter a non-dividing state called senescence can nevertheless boost cancer growth. The finding that these cells eat neighbouring cells reveals a mechanism that enables senescent cells to persist. Chemotherapy-treated tumours boost their survival by ingesting cells.
