Weird ‘Borg’ DNA May Have Assimilated Microbes For Billions of Years

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

Strange libraries of supplementary genes nicknamed “Borg” DNA appear to supercharge the microbes that possess them, giving them an uncanny ability to metabolize materials in their environment faster than their competitors.

By learning more about the way organisms use these unusual extrachromosomal packets of information, researchers are hoping to find new ways of engineering life to take a big bite out of methane emissions.

In the wake of a study publicized last year (and now published in Nature), researchers have continued to analyze the diversity of sequences methane-munching microbes store in these unusual genetic depositaries in an effort to learn more about the evolution of life.

Association between work characteristics and epigenetic age acceleration: cross-sectional results from UK — Understanding Society study

Posted by in categories: employment, genetics, life extension

Occupation-related stress and work characteristics are possible determinants of social inequalities in epigenetic aging but have been little investigated. Here, we investigate the association of several work characteristics with epigenetic age acceleration (AA) biomarkers.

The study population included employed and unemployed men and women (n = 631) from the UK Understanding Society study. We evaluated the association of employment and work characteristics related to job type, job stability; job schedule; autonomy and influence at work; occupational physical activity; and feelings regarding the job with four epigenetic age acceleration biomarkers (Hannum, Horvath, PhenoAge, GrimAge) and pace of aging (DunedinPoAm, DunedinPACE).

We fitted linear regression models, unadjusted and adjusted for established risk factors, and found the following associations for unemployment (years of acceleration): HorvathAA (1.51, 95% CI 0.08, 2.95), GrimAgeAA (1.53, 95% CI 0.16, 2.90) and 3.21 years for PhenoAA (95% CI 0.89, 5.33). Job insecurity increased PhenoAA (1.83, 95% CI 0.003, 3.67), while working at night was associated with an increase of 2.12 years in GrimAgeAA (95% CI 0.69, 3.55). We found effects of unemployment to be stronger in men and effects of night shift work to be stronger in women.

Role of spike in the pathogenic and antigenic behavior of SARS-CoV-2 BA.1 Omicron

Posted by in categories: biotech/medical, genetics

The recently identified, globally predominant SARS-CoV-2 Omicron variant (BA.1) is highly transmissible, even in fully vaccinated individuals, and causes attenuated disease compared with other major viral variants recognized to date1 7. The Omicron spike (S) protein, with an unusually large number of mutations, is considered the major driver of these phenotypes3,8. We generated chimeric recombinant SARS-CoV-2 encoding the S gene of Omicron in the backbone of an ancestral SARS-CoV-2 isolate and compared this virus with the naturally circulating Omicron variant. The Omicron S-bearing virus robustly escapes vaccine-induced humoral immunity, mainly due to mutations in the receptor-binding motif (RBM), yet unlike naturally occurring Omicron, efficiently replicates in cell lines and primary-like distal lung cells. In K18-hACE2 mice, while Omicron causes mild, non-fatal infection, the Omicron S-carrying virus inflicts severe disease with a mortality rate of 80%. This indicates that while the vaccine escape of Omicron is defined by mutations in S, major determinants of viral pathogenicity reside outside of S.

The authors have declared no competing interest.

Common diabetes medication identified as a possible treatment for atrial fibrillation

Posted by in categories: biotech/medical, genetics

Cleveland Clinic researchers have identified a common diabetes medication, metformin, as a possible treatment for atrial fibrillation.

The study, published in Cell Reports Medicine, built on ongoing collaborative Cleveland Clinic research to support further investigation into metformin as a drug repurposing candidate. Researchers used advanced computation and genetic sequencing to determine that metformin’s targets overlap significantly with genes dysregulated in atrial fibrillation.

Finding drugs or procedures to treat atrial fibrillation is difficult because of potential serious side effects. There is a significant need for new treatments for atrial fibrillation as there have been no new drugs approved in more than a decade.

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.
