Gene Therapy Treatment Uses Microparticles to Deliver DNA or RNA

A novel gene therapy approach for correcting hereditary blood disorders is based on the use of megakaryocytic microparticles (MkMPs) to deliver plasmid DNAs and small RNAs to hematopoietic stem and progenitor cells (HSPCs). More...

DNA Methylation Pattern May Be Biomarker for Cancer Detection

A team of Australian researchers has determined that a characteristic pattern of methylated DNA allows for easy detection of the genomes of cancerous cells and may serve as a universal biomarker for rapid diagnosis of many types of cancer. More...

Nanoparticle Assay Detects Respiratory Bacteria in Pneumonia Model

Researchers used a mouse pneumonia model to demonstrate how a nanoparticle-based technique could be used to detect Pseudomonas aeruginosa bacteria in infected animals and monitor bacterial clearance from their lungs during the course of antibiotic treatment. More...

Deeply Penetrating Nanoparticles Designed to Treat Osteoarthritis

A novel nanoparticle-based drug transport system designed to treat osteoarthritis delivers the anabolic growth factor IGF-1 (insulin-like growth factor 1) directly to injured chondrocytes, which are located deep within a dense layer of cartilage tissue. More...

Diabetes Researchers Convert Stem Cells into Insulin-Producing Cells

A team of stem cell biologists working on the problem of pancreas replacement in patients with type I diabetes identified the extrinsic and intrinsic signaling mechanisms that coordinate the fate-determining transcriptional events underlying the maturation of bipotent pancreatic progenitors and used this information to convert these pancreatic progenitors - derived from human embryonic stem cells - to insulin-producing islet cells.

Nishimasu, who discovered and published the coordinates of each atom in the protein-DNA complex. James Rybarski used those coordinates and software called PyMol to generate the illustration).

Analytical Tools Reveal Molecular Mechanism of Gene-Editing Tool

A recent paper described the use of advanced analytical techniques to define the mode of action of the gene-editing tool CRISPR/cas12. More...
