Their findings, published in the journal Nature…
Viruses are often used as vehicles for delivery in gene therapy because they’re engineered not to damage the cell once they get there, but neglecting to consider how the virus will exit the cell could have consequences. Some viruses use a molecule called heparan sulfate to help them attach to cells. The molecule, found in many different kinds of cells (including those from animal tissue), could…
Pathological infertility is a condition affecting roughly 7% of human males, and among those afflicted, 10-15% are thought to have a genetic cause. However, pinpointing the precise genes responsible for the condition has been difficult, due to the extensive number involved in generating and developing sperm cells. In a new paper appearing in Science Signaling, a Japanese team reports unravelling…
Tumours change over time – and not only in size. They also evolve genetically, mutate and spread through equally diverse metastases. Each is unique and present with a more or less complex structure, but rarely as a unified entity. Characterising them from A to Z and from detection to neutralisation remains a challenge for modern medicine.
