Prof. Rotem Sorek’s lab at the Weizmann Institute of Science has revealed the role retrons play in bacteria, finding that the hybrid structures are immune system guards that ensure the bacteria’s survival when it is infected by viruses. In addition, the team hopes that newly identified retrons will improve genome-editing tools.
Cancer-Fighting Gene Restrains ‘Jumping Genes’
DALLAS – Oct. 29, 2020 – About half of all tumors have mutations of the gene p53, normally responsible for warding off cancer. Now, UT Southwestern scientists have discovered a new role for p53 in its fight against tumors: preventing retrotransposons, or “jumping genes,” from hopping around the human genome. In cells with missing or mutated p53, the team found, retrotransposons move and multiply more than usual. The finding could lead to new ways of detecting or treating cancers with p53 mutations.
Can Gene Editing and Gene Therapy Techniques Combine to Treat Angelman Syndrome?
Babies born with a faulty maternal copy of the UBE3A gene will develop a severe neurodevelopmental disorder with no cure and limited treatments. Now, scientists show that gene editing/gene therapy techniques can be used to restore UBE3A in human neuron cultures and treat deficits in an animal model.
Regulators Classify Gene-Edited Rice Varieties with Disease Resistance as Equivalent to Conventional Varieties
The Healthy Crops team, with support from the Bill & Melinda Gates Foundation, have used gene editing tools to develop new varieties of disease-resistant rice that regulators in the United States and Colombia have determined are equivalent to what could be accomplished with conventional breeding.
