The difference between an immune response that kills cancer cells and one that conversely stimulates tumor growth can be as narrow as a "double-edged sword," report researchers at the University of California, San Diego School of Medicine in the April 7, 2014 online issue of the Proceedings of the National Academy of Sciences.
Inactivation of 2 genes may have allowed escape from bacterial pathogens, researchers say.
Researchers say that losing the ability to make a particular kind of sugar molecule boosted disease protection in early hominids, and may have directed the evolutionary emergence of our ancestors, the genus Homo.
Researchers at the University of California, San Diego School of Medicine say antibodies to a non-human sugar molecule commonly found in people may be useful as a future biomarker for predicting cancer risk, for diagnosing cancer cases early and, in sufficient concentration, used as a treatment for suppressing tumor growth.
Researchers say an evolutionary gene mutation that occurred in humans millions of years ago and our subsequent inability to produce a specific kind of sialic acid molecule appears to make people more vulnerable to developing type 2 diabetes, especially if theyâ€™re overweight.
The glycome, encompassing all of the complex sugars produced by an organism, is comprised of multiple families of molecules whose function in the human body is often determined by the structure, composition, and placement of the attached sugars, as explored in a comprehensive look at the field of glycomics in a group of key articles in OMICS: A Journal of Integrative Biology.
Researchers at the University of California, San Diego School of Medicine have discovered that a kind of sugar molecule common to chimpanzees, gorillas and other mammals but not found in humans provokes a strong immune response in some people, likely worsening conditions in which chronic inflammation is a major issue.
Group B Streptococcus (GBS), a bacterial pathogen that causes sepsis and meningitis in newborn infants, is able to shut down immune cell function in order to promote its own survival
Researchers at the University of California, San Diego School of Medicine, led by Ajit Varki, MD, have shown a new mechanism for how human consumption of red meat and milk products could contribute to the increased risk of cancerous tumors.
- The act of burning, scorching, or heating to dryness; the state or being thus heated or dried.
- In medicine, cauterization.
