PB Transposon Mutagenesis Identifies Malaria Genes and Drug Targets

A team of genome researchers took advantage of the unusual nucleotide composition of Plasmodium falciparum DNA to create mutant strains of the malaria parasite in order to identify essential genes and potential drug targets. More...

Novel Biopsy Enabled by Focused Ultrasound and Microbubbles

A recent paper discussed the feasibility of using focused ultrasound in combination with microbubbles to generate the local release of mRNA from a glioblastoma tumor into the bloodstream for diagnosis of brain cancer by non-invasive liquid biopsy analysis. More...

Minor Blood Group Antigens Deleted by Gene Editing

The CRISPR/Cas9 gene-editing tool was used to create a line of red blood cells for transfusion that was completely deficient in blood groups encoded by five different genes that generate antigens responsible for the most common transfusion incompatibilities. More...

Nanoparticle Delivery Increases Effectiveness of Anti-Cancer Immunotherapy

A nanoparticle delivery system was used to transport antibody-based immunotherapeutic drugs in trials conducted in cancer cell in vitro cultures and in animal models. More...

Image: The long non-coding RNA called A-ROD is only functional the moment it is released from chromatin into the nucleoplasm. At this transient phase, it can bring transcription factors to specific sites in DNA to enhance gene expression. After its complete release from chromatin, A-ROD is no longer active (Photo courtesy of Evgenia Ntini, Max Planck Institute for Molecular Genetics).

Transcription Regulation Depends on Release from Chromatin

A team of German genome researchers has demonstrated that release from chromatin is a crucial functional aspect of long noncoding RNAs in transcription regulation of their target genes. More...

Model Demonstrates Potential for Long-Term Gene Silencing

An adeno-associated viral (AAV) vector was used to deliver a modified version of the CRISPR/Cas9 gene-editing tool to liver cells in a mouse model, which resulted in suppression of the serum enzyme Pcsk9 and reduction of cholesterol levels. More...

Protein Droplets Stimulate Neurodegenerative Fibril Clumping

A team of neurodegenerative disease researchers has identified a molecular mechanism that prevents or reverses the formation of insoluble protein aggregates that characterize several brain disorders, including frontotemporal dementia (FTD) and amyotrophic lateral sclerosis (ALS). More...
