Nanorobot hand made of DNA grabs viruses for diagnostics and blocks cell entry

Science Daily: Pharmacology News

A tiny, four-fingered 'hand' folded from a single piece of DNA can pick up the virus that causes COVID-19 for highly sensitive rapid detection and can even block viral particles from entering cells to infect them, researchers report.

Gene editing extends lifespan in mouse model of prion disease

Broad Institute

The treatment, which uses base editing to make a single-letter change in DNA, reduced levels of the disease-causing prion protein in the brain by as much as 60 percent. A base-editing approach could also likely be a one-time treatment for all prion disease patients regardless of the genetic mutation causing their disease.

Editing without 'cutting': Molecular mechanisms of new gene-editing tool revealed

Science Daily: Pharmacology News

Functional analysis based on these structures also revealed how a 'prime editor' could achieve reverse transcription, synthesizing DNA from RNA, without 'cutting' both strands of the double helix. Clarifying these molecular mechanisms contributes greatly to designing gene-editing tools accurate enough for gene therapy treatments.

Chemical Biology and Drug Design

Subsequently, 2-HG competitively suppresses a range of -KG-dependent dioxygenase activities, ultimately leading to hypermethylation of DNA or histones, which in turn causes the occurrence of various malignant tumors, including acute myeloid leukemia (AML), glioma, and chondrosarcoma.
