Prostate ‘growth’ gene identified

Prostate ‘growth’ gene identified

3 August 2012 Last updated at 20:13 ET Scientists from Edinburgh University have pinpointed a gene they say could lead to improvements in the diagnosis and treatment of prostate cancer. The team studied genes that control the formation of the prostate gland and identified one known as Decorin Continue reading

Stem cells drive tumour growth

Stem cells drive tumour growth

1 August 2012 Last updated at 13:00 ET By Pallab Ghosh Science correspondent, BBC News Researchers have discovered the cells in tumours that seem to be responsible for the regrowth of tumours. Three separate studies on mice appear to have confirmed the view that the growth of tumours is driven by so-called cancer stem cells. The researchers claim to have resolved one of the biggest controversies in cancer research and say their work marks a “paradigm shift” in the field Continue reading

Feces fossils show connection between Native-Americans, diabetes: Did fat-hoarding genes develop from the nature of ancient feasts?

Feces fossils show connection between Native-Americans, diabetes: Did fat-hoarding genes develop from the nature of ancient feasts?

ScienceDaily (July 24, 2012) — Why do Native Americans experience high rates of diabetes? A common theory is that they possess fat-hoarding “thrifty genes” left over from their ancestors — genes that were required for survival during ancient cycles of feast and famine, but that now contribute to the disease in a modern world of more fatty and sugary diets. A newly published analysis of fossilized feces from the American Southwest, however, suggests this “thrifty gene” may not have developed because of how often ancient Natives ate. Continue reading

New line of approach for combination therapy against Melanoma

New line of approach for combination therapy against Melanoma

ScienceDaily (July 20, 2012) — A melanoma is a malignant form of skin cancer and is one of the most aggressive types of tumors there is. Treatment is particularly difficult, because melanomas are usually resistant against conventional chemotherapy treatments. Agnieszka Gembarska and Chris Marine (VIB/KU Leuven) have found a new line of approach in which to treat these aggressive skin cancers, namely by combating the interaction between the protein MDM4 and the tumor suppressor p53 Continue reading

Why the thrill is gone: Potential target for treating major symptom of depression

Why the thrill is gone: Potential target for treating major symptom of depression

ScienceDaily (July 11, 2012) — Stanford University School of Medicine scientists have laid bare a novel molecular mechanism responsible for the most important symptom of major depression: anhedonia, the loss of the ability to experience pleasure. While their study was conducted in mice, the brain circuit involved in this newly elucidated pathway is largely identical between rodents and humans, upping the odds that the findings point toward new therapies for depression and other disorders. Additionally, opinion leaders hailed the study’s inventive methodology, saying it may offer a much sounder approach to testing new antidepressants than the methods now routinely used by drug developers.

Urinary infections steal from hosts’ defense arsenals

Urinary infections steal from hosts’ defense arsenals

ScienceDaily (July 8, 2012) — Humans have known for centuries that copper is a potent weapon against infection. New research shows that the bacteria that cause serious urinary tract infections “know” this, too, and steal copper to prevent the metal from being used against them Continue reading

Teen sexting prevalent: Nearly 30 percent send nude pictures despite being ‘bothered’ by requests

Teen sexting prevalent: Nearly 30 percent send nude pictures despite being ‘bothered’ by requests

ScienceDaily (July 2, 2012) — A study of students at seven public high schools in Texas suggests that “sexting” was prevalent and may be linked to teens’ sexual behaviors, according to a report published Online First by Archives of Pediatrics & Adolescent Medicine, a JAMA Network publication.

New way to grow, isolate cancer cells may add weapon against disease

New way to grow, isolate cancer cells may add weapon against disease

ScienceDaily (July 2, 2012) — The news a cancer patient most fears is that the disease has spread and become much more difficult to treat. A new method to isolate and grow the most dangerous cancer cells could enable new research into how cancer spreads and, ultimately, how to fight it. Continue reading

Care homes ‘failing vulnerable’

Care homes ‘failing vulnerable’

25 June 2012 Last updated at 10:02 ET Almost half of all care homes and treatment centres in England are failing to protect the welfare of vulnerable adults, a report says. Unannounced inspections were carried out by the Care Quality Commission (CQC), 1 England’s health regulator Continue reading

Milk fat link to bowel disease

14 June 2012 Last updated at 05:10 ET By James Gallagher Health and science reporter, BBC News The rise of inflammatory bowel diseases could be down to our shifting diets causing a “boom in bad bacteria”, according to US researchers. Continue reading
