Researchers have identified miR-124 signaling and its effects on AMPA receptor neurotransmission as a biological mechanism linking the shared risk scores of schizophrenia and bipolar disorders to their shared symptoms. The work, which appeared online in Neuron on Nov. 14, 2022, focused on schizophrenia and bipolar disorder, which are both highly heritable disorders that share substantial risk. Beyond their implications for those two specific disorders, the findings illustrate a path to connecting risk scores and behaviors via their biological link.
Researchers from Children's Hospital Los Angeles presented data from a study that linked a homozygous missense mutation in ARSK to a new subtype of the lysosomal storage disease mucopolysaccharidoses (MPS).
Modern molecular techniques have progressed to the point where sequencing can seem almost quaint. At the Basic Science Symposium of the American Association for the Study of Liver Diseases 2022 meeting (AASLD 2022), new techniques were on full display, with sessions devoted to epigenetics, microbiome analysis and spatial transcriptomics. But the first session was still on genetic variants in all their forms – rare variants, common variants and nongermline mutations.
JCR Pharmaceuticals Co. Ltd. has decided to develop a new drug candidate, JR-471, a blood-brain barrier (BBB)-penetrating α-L-fucosidase for the treatment of patients with the inherited lysosomal storage disorder fucosidosis.
Dystroglycanopathies are a subset of rare congenital muscular dystrophies (CMDs) caused by dysregulation in the assemblage of glycans on the α-dystroglycan (α-DG) transmembrane glycoprotein.
Disrupted meiosis, the cell division process that leads to the production of reproductive cells in sexually reproducing organisms, led to a decline in overall health by triggering an accelerating aging signature in the roundworm Caenorhabditis elegans.
The work is “the first direct evidence that manipulating the health of reproductive cells leads to premature aging and a decline in healthspan,” senior author Arjumand Ghazi, an associate professor of pediatrics, developmental biology, and cell biology and physiology at the University of Pittsburgh and the University of Pittsburgh Medical Center (UPMC) Children’s Hospital, said in a press release.
