New Molecular Regulators Of Hyperthyroidism And Goiter

New Molecular Regulators Of Hyperthyroidism And Goiter
Thyroid gland function is regulated by the hormone TSH. Increased levels of TSH and increased signaling through its receptor cause hyperthyroidism and goiter. Signals downstream of the receptor for TSH were thought to be mediated mainly by the Gs protein complex. A new study now indicates that in mice Gq/G11-mediated signaling has an essential role in transmitting TSH-induced signals. This makes Gq and G11 potential new targets for the treatment of hyperthyroidism and goiter.

Study: Loading Up on Fruits and Veggies Won't Lower Breast Cancer Recurrence
If eating 5 servings of fruits and vegetables a day is good for you, then 10-a-day must be twice as good, right? Not necessarily.

Grapefruit Linked to Breast Cancer?
Could eating lots of grapefruit raise your breast cancer risk? Experts say more research is needed to know for sure.

Physicians Test New Device For Diagnosing And Treating Prostate Cancer
A clinical trial is testing a new mechanical device called TargetScan aimed at improving prostate cancer detection and helping to provide detailed medical information. Preliminary tests indicate it can improve doctors' ability to detect cancer and could lead to more targeted treatments--reducing life-altering side effects like impotence and incontinence.

Diabetes During Pregnancy Linked To Pancreatic Cancer Later
Pregnancies in Jerusalem in the 1960s and 1970s may hold vital clues about how pancreatic cancer and diabetes are linked. According to new research, women with a history of gestational diabetes had a higher risk of developing pancreatic cancer later in life.
