Men’s blood has higher levels than women’s of a key enzyme used by the new coronavirus to infect cells, the results of a big European study showed on Monday — a finding which may help explain why men are more vulnerable to infection with COVID-19.
Researchers at the George Washington University (GW) Cancer Center found that the enzyme USP15 could potentially lead to new treatments for breast and pancreatic cancer. Their findings were published in Nature Communications.
Scientists at the University of Würzburg have chemically modified the enzyme levansucrase using a new method. The enzyme can now produce sugar polymers that are exciting for applications in the food industry and medicine.
Like a genetic handyman, an elusive enzyme deep inside certain cells repairs the tips of chromosomes, which fray as cells divide. It’s prized by rapidly dividing cells – like stem cells and tumor cells – and by scientists on the hunt for cancer and other disease therapies.
Bacteria may not have brains, but they do have memories, at least when it comes to viruses that attack them. Many bacteria have a molecular immune system which allows these microbes to capture and retain pieces of viral DNA that they have encountered in the past, in order to recognize and destroy it when it shows up again.
A compound that effectively inhibits an enzyme crucial to the viruses that cause Middle East Respiratory Syndrome (MERS) and Severe Acute Respiratory Syndrome (SARS) has been identified by University of Illinois, Chicago scientists.
