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.
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.
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.
Despite a century of research, there are no specific treatments for acute or persistent ocular SM injuries. SM cytotoxicity emerges, in part, through DNA alkylation and double-strand breaks (DSBs). Significance Statement Sulfur Mustard Gas corneal injury currently has no therapeutic treatment.
MGMT mRNA expression was significantly increased in CD138+ myeloma cells compared with their matched CD138-nontumorigenic cells and inhibition of MGMT by its specific inhibitor lomeguatrib in MM cells reduced DNA repair, cell viability, and S phase entry and increased DNA damage and apoptosis.

FDA classifies it as a “nonsteroidal treatment” – not a gene therapy, but it affects gene expression. A gene-based treatment would have to alter many cells to exert a noticeable effect. million DNA bases. In 2023, two gene-based treatments became available. What’s an HDAC Inhibitor?
The most comprehensive analysis of Indigenous Australians’ genomes collected to date has revealed an “abundance” of DNA variations – some of which have never been reported anywhere else in the world – paving the way for new, personalised treatments that address health inequities for Aboriginal and Torres Strait Islander peoples.
GBM has a poor prognosis despite aggressive treatment, in part due to lack of adequate drug permeability at the BBB. Standard of care GBM therapies include radiation and cytotoxic chemotherapy that lead to DNA damage. Subsequent activation of DNA damage response (DDR) pathways can induce resistance.
Mutations in the TRF2TRFH domain physically impair t-loop formation and prevent the recruitment of several factors that promote efficient telomere replication, causing telomeric DNA damage. We identify APOD53 as our most promising compound, as it consistently induces a telomeric DNA damage response in cancer cell lines.
It was found that combining these drugs with lower doses and for shorter treatment periods induced greater or equal toxicity in cancer cells than using either as a single agent. Here, we develop a mathematical model to investigate the effects of ceralasertib and olaparib, two drugs that target DNA damage response pathways.
Base editing, which Lius team developed in 2016, is a gene editing technique that directly converts an individual DNA base pair into a different base pair. Liu and other prize recipients were announced on April 5, 2025, at the 11th annual Breakthrough Prize ceremony in Los Angeles.

• Genomic sequencing panels are tests that analyse the DNA of the patient’s tumour to look for genetic variants for which there are effective drugs. If the tumour has these variants, treatment can be personalised.
Radiation therapy, a standard treatment option for many cancer patients, induces DNA double strand breaks (DSBs), leading to cell death. This approach will provide critical insights for the clinical translation of WSD0628 for the treatment of primary and secondary brain tumors.
Recombinant DNA technology has since provided a pure source of the hormone. This transmission occurred following treatment with a now obsolete form of growth hormone, and involved repeated treatments with contaminated material, often over several years. At least 1,848 patients with short stature developed vCJD, mostly in the UK.
2 DNA repair mechanism disruption is a significant cause of increased cancer risk, with around 20 percent of bowel cancers known as mismatch repair deficient (MMRd) cancers, which have mutations in DNA repair genes. She continued: “The really interesting finding from our research is what happens afterwards.
2 Unmet needs in lung cancer treatment Recent decades have seen significant advancements in lung cancer treatment, especially with the introduction of targeted therapies and immunotherapies, which have notably improved survival rates. 7 Recent clinical studies highlight promising developments in c-MET-targeting ADCs for NSCLC.
No dose-limiting toxic effects or treatment-related deaths were reported. Treatment-related adverse events occurred in 127 patients (93%); grade 3 events occurred in 15 patients (11%) and a grade 4 event in 1 patient (1%). Among patients with NSCLC, a confirmed response was observed in 53.4% months (95% CI, 8.8
Diagnosis began to shift from a body-part basis to a molecular one, which I wrote about in “Mutation and location important in cancer treatment” for The Lancet in 2015. These findings can then be used to predict response to treatments as well as survival time. More information enables more treatment choices.
This study identified MAPK9 as the directly binding target of baicalein by the DNA-programmed affinity labeling method and tested the binding affinity as 89.7 nM However, there are limited effective treatments available for it.
