Two proteins work hand in hand to ensure that the tumor cells of neuroblastoma can grow at full speed. In Nature, a Würzburg research team shows how the proteins can do this.
It has been known for decades that cancer cells have an altered metabolism and it is seen in several biochemical pathways and in particular, in the way they get energy for their survival. Now, a new article describes an epigenetic injury found in human tumours which created this altered path to take energy from the cancer.
As the FDA looks for more information on e-cigarettes and e-juice flavors, a new Dartmouth study shows that adolescents and young adults cite appealing flavors as a main reason for using e-cigarettes, that they are more likely to turn to fruit- and candy-flavored cigarettes than adult smokers trying to quit who more commonly prefer tobacco flavors, and that the younger population are likely to use multiple e-cigarette flavors at the same time.
SDSU researchers found at least some smokers with kids will modify their behavior with an electronic push.
People who vaped were nearly twice as likely to experience wheezing compared to people who didn't use tobacco products, according to a study published in Tobacco Control. The findings are consistent with past research that shows emissions from e-cig aerosols and flavorings damage lung cells by generating harmful free radicals and inflammation in lung tissue. Study authors say the take-home message is that electronic cigarettes are not safe when it comes to lung health.
Researchers from the University of Copenhagen have identified a specific mechanism that protects our cells from natural DNA errors -- an 'enemy within' -- which could permanently damage our genetic code and lead to diseases such as cancer. The study has just been published in one of the most influential scientific journals, Nature Cell Biology.
Scientists have discovered a defect in immune cells known as 'killer T cells' that explains their inability to destroy cancer tumors. The researchers believe that repairing this defect could make the cells much better cancer killers.
An analysis of cervical precancers over a period of seven years showed that two strains of human papillomavirus (HPV) that have been targeted by vaccination since 2006 have declined, accounting for a smaller proportion of cervical disease. The study offers evidence that HPV vaccination reduced the incidence of infections that can lead to cervical cancer.
Children living in homes with all vinyl flooring or flame-retardant chemicals in the sofa have significantly higher concentrations of potentially harmful semi-volatile organic compounds (SVOCs) in their blood or urine than children from homes where these materials are not present, according to new Duke University-led research. The researchers presented their findings Feb. 17 at the annual meeting of the American Association for the Advancement of Science in Washington, D.C.
A USC study in 93 people shows that e-cig users develop some of the same cancer-related molecular changes in oral tissue as cigarette smokers, adding to the growing concern that e-cigs aren't a harmless alternative to smoking.
