Specific sugar molecule causes growth of cancer cells
The process of glycosylation, where sugar molecules are attached to proteins, has long been of interest to scientists, particularly because certain sugar molecules are present in very high numbers in cancer cells. It now turns out that these sugar molecules are not only present but actually aid the growth of the malignant cells. In the long term this discovery is an important step towards a cure that can stop the growth of cancer cells. (2013-09-16)

Sugar-coated antibiotics
Researchers from the John Innes Centre and the University of East Anglia have recently elucidated the structure and function of an enzyme which is involved in decorating antibiotics with sugar molecules.

By manipulating the sugar, it may be possible to restore usefulness in antibiotics to which resistance has developed. (2008-05-28)

Blocking sugar structures on viruses and tumor cells
During a viral infection, viruses enter the body and multiply in its cells. Viruses often specifically attach themselves to the sugar structures of the host cells, or present characteristic sugar structures on their surface themselves. Researchers at the Technical University of Munich (TUM) have developed a new type of protein reagent for identifying biological sugar structures, which may block the spread of an illness in the body if used for blocking the sugar structures of a cell or a pathogen. (2020-03-17)

For cancer patients, sugar-coated cells are deadly
Every living cell's surface has a protein-embedded membrane that's covered in polysaccharide chains -- a literal sugar coating. A new study by a Cornell University researcher found this coating is especially thick and pronounced on cancer cells and is a crucial determinant of the cell's survival. Consisting of long, sugar-decorated molecules called glycoproteins, the coating causes physical changes in the cell membrane that make the cell better able to thrive -- leading to a more lethal cancer. (2014-07-01)

New technique paves way for medical discoveries
