Schizophrenia (SCZ) could be associated with genetic alterations that can appear at the beginning of life. Such somatic variants in the NRXN1 and ABCB11 genes could lead to SCZ, according to researchers at Boston Children’s Hospital.
Alterations in chromosome number can play a role in cancer progression. An analysis of recurrent aneuploidies, such as the duplication of the long arm of chromosome 1, revealed that it was required for the proliferation of cancer cells carrying this alteration, an effect that was similar to so-called oncogene addiction. These findings have therapeutic implications that could benefit cancer patients depending on the genetic singularity of their tumor cells.
At the 2023 Annual Congress of the European Academy of Neurology, Mary Reilly described the relationship between bench and bedside as “a continuous circle of translation,” with each cycle beginning with patients and their needs.
It seems unlikely that American poet and civil rights activist Maya Angelou spent much time thinking about translational research. But two quotes of hers capture the essence of the interplay between bench and bedside: “I did then what I knew how to do. Now that I know better, I do better” and “I’ve learned that I still have a lot to learn.” At the 2023 Annual Congress of the European Academy of Neurology, Mary Reilly described the relationship between bench and bedside as “a continuous circle of translation,” with each cycle beginning with patients and their needs.
Duchenne muscular dystrophy (DMD) is an X-linked genetic disorder affecting roughly 1 in 3,500 males. DMD is due to mutations in the dystrophin gene, which encodes for an exceptionally large 427 kD protein. DMD is characterized by repeated degeneration and regeneration of muscle fibers, but ultimately replacement of muscle with fibrotic and adipose tissue. Despite advances in gene therapy and improvements in quality of life, most patients still die by 30 years of age due to cardiopulmonary failure.
ΔF508 is the most prevalent mutation detected in patients with cystic fibrosis (CF), and it causes a loss of F508 within CFTR’s first nucleotide binding domain (NBD1). Researchers from Sionna Therapeutics Inc. recently reported the discovery and preclinical evaluation of novel small-molecule CFTR NBD1 stabilizers and CFTR assembly correctors as potential new agents for the treatment of CF.
The unprecedented rise in life expectancy has made advances in the understanding of biological hallmarks of aging, at both the molecular and cellular levels, essential. A joint effort between Baylor College of Medicine, Genentech Inc., Stanford University and collaborating institutions has led to the release of the first Aging Fly Cell Atlas (AFCA) as a result of a deep dive analysis of 163 different cell types in Drosophila melanogaster, the common fruit fly.
Primary lymphedema (PL) is a chronic condition that results from abnormal development or functioning of the lymphatic system caused by gene mutations. Researchers from St George's University of London and colleagues reported the identification of novel variants in the ERG gene during their study performed through whole genome analysis of PL cases included in the 100,000 Genomes Project.
New research shows base and prime editing can correct some forms of phenylketonuria (PKU) in mice and human cell lines, raising the prospect that this gene-editing approach could allow children born with the inherited metabolic disorder to have a treatment that would avoid the need for dietary restrictions and medication.
