Self-Deleting Genes Project To Tackle Mosquito-Borne Diseases

D. Ozdemir,  INTERESTING ENGINEERING,  2021.
Did you know that mosquitoes kill at least 725,000 persons every year? They truly are one of the world's deadliest animals which is the reason why scientists from all around are trying to find new ways of dealing with them. Controlling mosquito populations and preventing them ...

Edit, undo: Temporary gene editing could help solve the mosquito problem

L. Dormehl,  digitaltrends,  2020.
But if SyFy original movies have taught us anything, it’s that genetically tweaking organisms and then releasing them can… well, not go quite according to plan.With that in mind, a new Texas A&M AgriLife Research project seeks to test out genetic modifications of mosquitos ...

Self-deleting genes tested as part of the concept of mosquito population control

charlottelarson,  NEWYORK NEWS TIMES,  2020.
Most genetic engineering strategies designed to control mosquito populations, and their ability to spread diseases such as malaria, require gene editing to be combined with gene drives. Gene drives allow altered DNA to spread rapidly throughout the population.

A Gene Drive Could Wipe Out Mosquitoes. But What If We Want To Turn It Off?

A. Winkler,  freethink,  2020.
Gene drives are powerful tools: they allow scientists to hack how animals pass down genes to their offspring. They could allow us to wipe out malaria-carrying mosquitoes, preserve endangered species, or fight off crop-eating pests. But once it's out in the wild, a gene drive ...

Active Genetic Neutralizing Elements for Halting or Deleting Gene Drives

X.-R. S. Xu, E. A. Bulger, V. M. Gantz, C. Klanseck, S. R. Heimler, A. Auradkar, J. B. Bennett, L. A. Miller, S. Leahy, S. S. Juste, A. Buchman, O. S. Akbari, J. M. Marshall and E. Bier,  Molecular Cell,  2020.
Here we describe two self-copying (or active) guide RNA-only genetic elements, called e-CHACRs and ERACRs. These elements use Cas9 produced in trans by a gene drive either to inactivate the cas9 transgene (e-CHACRs) or to delete and replace the gene drive (ERACRs).
