New genome-editing technologies can help understand disease-associated genetic mutations

New genome-editing technologies developed by researchers in J. Keith Joung's laboratory at the Massachusetts General Hospital (MGH) have the potential to help understand disease-associated genetic mutations that are based on C-to-G (cytosine to guanine) single base changes.

Epigenomic modifications play key role in the development of lung tumors

As cancer cells evolve, many of their genes become overactive while others are turned down. These genetic changes can help tumors grow out of control and become more aggressive, adapt to changing conditions, and eventually lead the tumor to metastasize and spread elsewhere in the body.

Gene in fat cells plays a key role in regulating insulin sensitivity

Deleting a key gene in mice in just their fat made tissues throughout these animals insulin resistant, in addition to other effects, a new study by UT Southwestern researchers shows.

People who carry the Neandertal variant of ion channel experience more pain

As several Neandertal genomes of high quality are now available researchers can identify genetic changes that were present in many or all Neandertals, investigate their physiological effects and look into their consequences when they occur in people today.

Findings could help design vaccines against coronavirus

Scientists investigating the evolution of the virus that causes Covid19 say that its mutation seems to be directed by human proteins that degrade it, but natural selection of the virus enables it to bounce back. The findings could help in the design of vaccines against the virus.

UNH scientists identify quicker and less expensive way to count sperm in lobsters

Researchers at the University of New Hampshire have identified a quicker and less expensive way to count sperm in lobsters that could help scientists looking at any animal better understand mating, a key aspect of species survival.

Newly identified enzyme provides a new tool in CRISPR genome editing toolbox

A recently discovered hypercompact CRISPR enzyme found only in huge bacteriophages, and known as CRISPR-CasΦ, is functional, a new study by Patrick Pausch, Jennifer Doudna and colleagues reports, and it provides a powerful new tool in the CRISPR genome editing toolbox, including because it can target a wider range of genetic sequences compared to Cas9 and Cas12.
