A new study discusses the origin of the furin cleavage site on the SARS-CoV-2 spike protein, which is responsible for the virus’s relatively high infectivity compared to relatives in the betacoronavirus subgenus.
An innovative approach to treating bone tumors - starving cancer cells of the energy they need to grow - could one day provide an alternative to a commonly used chemotherapy drug without the risk of severe side effects, suggests a new study from Washington University School of Medicine in St. Louis.
Researchers define tumor invasion machinery orchestrated by a master cancer gene Researchers investigated how cancer genes lead to the breakdown of the capsule that prevents cancerous cells from invading the surrounding healthy tissues and - find a hijacked "molecular crowbar". The new findings help understand the mechanisms of cancer spreading and reveal a cancer vulnerability. Researchers at the University of Helsinki have defined a cancer invasion machinery, which is orchestrated by a frequently mutated cancer gene called Ras. When signaling from Ras protein becomes abnormally high, like i...
Study reveals new way to target cancer’s nutritional needs Jan 18 2021 Scientists discover a way to target cancer’s nutritional needs, which could lead to a new way to treat the disease, according to a study published in Nature Communications today (Thursday). Numerous studies in mice and cancer cells have shown cancer growth can be reduced in response to diets lacking serine. But results have been variable because some cancer cells are efficient in making their own serine, particularly those with a KRAS mutation which is found in several hard-to-treat cancers. The scientists in today’...
The human organism requires a variety of small molecules, such as sugars or fats, in order to function properly.
