Researchers have discovered that a subunit of the ubiquitin-proteasome system acted independently of the proteasome machinery to regulate AMPA receptors, a type of glutamate receptor, at multiple steps of their life cycle. Published in the May 26, 2023, issue of Science, the findings could point to ways to target AMPA receptors. They are responsible for the majority of excitatory transmission in the central nervous system, and current drugs seeking to influence AMPA-based transmission are “good but they are not great,” Erin Schuman told BioWorld. “This regulatory particle is watching the glutamate receptor at each step.” Schuman is the director of the Max Planck Institute for Brain Research and the paper’s senior author.

Idiopathic pulmonary fibrosis (IPF) is a rare, progressive and chronic lung disease that causes scarring of the lung tissue and leads to an irreversible decline in lung function. Several studies have linked the p53 tumor suppressor gene to pulmonary fibrosis.
At the recent ATS meeting, Tavanta Therapeutics Inc. introduced TAVT-135, a cell-penetrating peptide (CPP) conjugate that acts as a chloride ion (Cl-) transporter. The product is currently being investigated for cystic fibrosis (CF), regardless of CF transmembrane conductance regulatory (CFTR) gene mutation status.
Hilleman Laboratories Singapore Pte Ltd. and the Agency for Science, Technology and Research (A*STAR) have established a collaboration to explore using novel circular ribonucleic acid (circRNA) technology to develop a Nipah virus vaccine and to validate the technology platform for application for other infectious diseases pathogens.
Sanford-Burnham Medical Research Institute has disclosed baculoviral IAP repeat-containing protein 7 (BIRC7; ML-IAP) inhibitors reported to be useful for the treatment of cancer.
Glioblastoma multiforme (GBM) is an aggressive brain cancer with poor prognosis and survival. TNF-related apoptosis-inducing ligand (TRAIL) is a protein that induces apoptosis in cancer cells by binding death receptors type 4 and 5. Researchers at the University of North Carolina explored using hiNeuroS-TRAIL combined with the ClpP activator TR-107 as a potential treatment.
Better times ahead for the biopharma sector? Could be, the new numbers say. Karen Carey, BioWorld’s managing editor and senior data analyst, and Tim Shannon, a general partner at Canaan, look at first quarter numbers and survey the big picture.
Sialidosis is a lysosomal storage disease caused by mutations in the NEU1 gene, which encodes sialidase neuraminidase 1. These mutations lead to enzyme deficiency and subsequently accumulation of oligosaccharides and sialylated glycopeptides in tissues and body fluids, which in turn lead to cell...
The targeted delivery of optimized stem cells directly into injured tissues has been used to maximize efficacy and minimize systemic exposure. Still, despite hundreds of clinical trials evaluating mesenchymal stem cell (MSC) therapy as a treatment, clinical efficacy remains highly variable....
NGGT (Suzhou) Biotechnology Co. Ltd. has presented preclinical data on an AAV vector approach that expresses human PAH, rAAV8-PAH, also known as NGGT-002. NGGT-002 has liver tropism and it was codon-optimized for expressing PAH in the liver.
Researchers from Healios K.K. presented preclinical data for HLCN-061, a novel gene-engineered human induced pluripotent stem cell (iPSC)-derived NK cell product being developed for the treatment of solid tumors.
Renal medullary carcinoma (RMC) is characterized by the complete loss of the SMARCB1 tumor suppressor, and it predominantly affects individuals with sickle cell trait (SCT), characterized by increased sickling of red blood cells in the renal medulla. It has been previously demonstrated that RMC...
By sequencing the bacterial mRNA that bacteria break down (the degradome) during protein synthesis, a novel approach called 5PSeq was able to analyze how environmental exposure stress, including that of antibiotics, affected bacterial translational dynamics. This is what researchers from the...
F. Hoffmann-La Roche Ltd. and Hoffmann-La Roche Inc. have identified piperazinylsulfonylaryl compounds acting as UDP-2,3-diacylglucosamine hydrolase (LpxH) (bacterial) inhibitors.
Rabies virus is among the most neurotrophic known virus and it has a fatality rate of almost 100%. There is a need for antibody-induced protection in the central nervous system, since rabies virus can cross the blood-brain barrier but antibodies cannot. Investigators from Auburn University and the...
Amplo Biotechnology Inc. has been awarded a fast track phase I/II Small Business Technology Transfer (STTR) grant from the National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS) of the National Institutes of Health (NIH) to fund further development of AMP-201, an AAV-ColQ...
Researchers from HuidaGene Therapeutics Co. Ltd. have evaluated the effects of adenine base editing (ABE)-induced exon skipping of exon 50 in a humanized mouse model of Duchenne muscular dystrophy (DMD).
Neuronal ceroid lipofuscinosis, commonly known as Batten disease, is an inherited pediatric neurodegenerative lysosomal storage disease caused by mutations in the CLN5 gene. The disease is incurable and there is an urgent medical need for novel therapies. A murine model of Batten disease was...
Fabry disease is a metabolic disease characterized by a deficiency in the lysosomal α-galactosidase enzyme caused by mutations in the GLA gene. This leads to substrate accumulation in the lysosomes, cellular dysfunction and organ damage.
Researchers from Wenzhou Medical University and affiliated organizations have published data from a study that aimed to investigate the relationship between the tumor suppressor microRNA-143 (miR-143) and RNA-binding protein Musashi homolog 2 (MSI2), the abnormal expression of which has been...
Gastric cancer persists as the fourth leading cause of cancer-related deaths. Syndecans (SDCs) are a family of four transmembrane heparan sulfate proteoglycans involved in cell proliferation, migration and adhesion, among others, and syndecan-4 (SDC4) expression has been shown to be up-regulated...
Despite advances in diagnosis and treatment, cardiovascular disease remains the leading cause of death worldwide. Single-nucleotide polymorphisms (SNPs) in microRNAs are known to play important roles in acute coronary syndrome (ACS). MicroRNA 146a (miR-146a) is significantly upregulated in human...
