An international team of researchers has discovered 13 new regions of the genome associated with the timing of menopause.

These genes shed light on the biological pathways involved in reproductive lifespan and will provide insights into conditions connected to menopause, such as breast cancer and heart disease.

Menopause is a major hormonal change that affects most women when they are in their early 50s. The timing of menopause can have a huge impact on fertility, as well as influencing the risk of a range of common diseases such as breast cancer. It has been known for some time that genetic factors influenced the onset of menopause, however until recently very few genes had been identified.

In the new study, published in the journal Nature Genetics on 22 January 2012, Dr Anna Murray, University of Exeter, Peninsula College of Medicine and Dentistry (PCMD) Dr John Perry, PCMD and WTCHG, University of Oxford, and dozens of international collaborators, examined the genomes of over 50,000 women. They identified 13 novel gene regions associated with menopause onset, and confirmed four previously identified. Most of the 17 regions include genes related to DNA damage/repair or the immune system, whilst others are linked to hormonal regulation. (more…)

COLLEGE PARK, Md. — A nurse’s tender loving care really does ease the pain of a medical procedure, and grandma’s cookies really do taste better, if we perceive them to be made with love – suggests newly published research by a University of Maryland psychologist. The findings have many real-world applications, including in medicine, relationships, parenting and business. (more…)

Patients with metastatic melanoma taking the recently approved drug vemurafenib (marketed as Zelboraf) responded well to the twice-daily pill, but some of them developed a different, secondary skin cancer.

Now, researchers at UCLA’s Jonsson Comprehensive Cancer Center, working with investigators from the Institute of Cancer Research in London, Roche and Plexxikon, have elucidated the mechanism by which the drug excels at fighting melanoma but also allows for the development of skin squamous-cell carcinomas.

In 2005, news first broke that researchers in Scotland found unexpectedly low rates of cancer among diabetics taking metformin, a drug commonly prescribed to patients with Type II diabetes. Many follow-up studies reported similar findings, some suggesting as much as a 50-per-cent reduction in risk. How could this anti-diabetic drug reduce the risk of developing cancer and what were the mechanisms involved? (more…)
