Scientists identify genes that promote the growth and recurrence of skin cancer

Andrzej Dlugosz, M.D., a professor of dermatology in the U-M Medical School, and colleagues at the University of Michigan and the National Cancer Institute examined the functions of the Hedgehog (Hh) signaling pathway in basal cell carcinoma – the most common form of cancer – and uncovered a subset of tumor cells that were resistant to inhibition of the Hedgehog pathway.

Direct modulation of progesterone signaling appears to influence ovarian cancer risk

A woman's risk of ovarian cancer rises significantly if she carries either of two previously unexamined variations in the gene that codes for the progesterone receptor, according to a team of researchers led by scientists from the Keck School of Medicine of the University of Southern California.

Signaling molecule involved in osteoarthritis identified

Using naturally-occurring mutant mice with a defective collagen gene, scientists at Harvard have identified a signaling molecule involved in one of the most common causes of disability among the elderly in the United States, osteoarthritis.

Scientists have identified genes that promote the growth and recurrence of skin cancer

Dr. Andrzej Dlugosz and colleagues at the University of Michigan and the National Cancer Institute have examined the functions of the Hedgehog (Hh) signaling pathway in basal cell carcinoma, the most common form of cancer, and have uncovered a subset of tumor cells that are resistant to inhibition of the Hh pathway.

Ubiquitination protects against improper Notch signaling

The Notch pathway is an important molecular signaling mechanism whose existence has been known, or at least hinted at, for nearly a century since the identification of a mutant strain of Drosophila fruit flies with "notched" wings in Thomas Hunt Morgan's lab in 1910.

New findings clarify the role of NOD2, a key molecular player in Crohn's Disease

This week, researchers report new findings that clarify the role of NOD2, a key molecular player in Crohn's Disease, in the cellular signaling pathways that control inflammatory responses. NOD2's clinical relevance is clear from the fact that it is encoded by a Crohn's Disease susceptibility gene.

Why hair turns grey

Few things about growing older are as inevitable and obvious as "going gray," yet scientists have been unable to explain the precise cause of this usually unwelcome transformation.

Importance of the phosphatidylinositol 3 kinase (PI3K) pathway to breast cancer development

Because up to 75 percent of breast cancer patients have an abnormality in a specific cell signaling pathway, drugs that target different molecules along that pathway may be especially effective for treating the disease, says a researcher from The University of Texas M. D. Anderson Cancer Center.

High levels of a protein called LRP6 can make cancer cells more aggressive

The protein's ability to enhance tumor development suggests that the gene that codes for LRP6 is an oncogene--a gene that contributes to tumor development when overactivated.

Potential new protein marker for prognosis of breast and ovarian cancer

The researchers matched tumor samples to outcomes in about 100 patients diagnosed with either breast or ovarian cancer and found that a low level of Rab25 protein on a patient's cancer sample was associated with a better clinical outcome in both cancer types.

Brain protein called MC4R that plays a role in the urge to eat has now been found to influence appetite in a second way

A brain protein already known to play a central role in the "feast or fast" signaling that controls the urge to eat has now been found to influence appetite in a second way. The discovery identifies a potential new target for drugs against obesity.

Discovery of fundamental mechanism within cells that link obesity and type 2 diabetes

Researchers from the Harvard School of Public Health have discovered what they believe is the fundamental mechanism within cells that links two fast-rising public health threats: obesity and Type 2 diabetes.

Signaling pathway could be a valuable target for future drug therapies against systemic lupus erythematosus

Medical investigators at the Hospital for Special Surgery have identified an important new signaling pathway they believe could be a valuable target for scientists to aim at with future drug therapies that might one day reverse diseases such as systemic lupus erythematosus, according to a recent article published in “Nature Immunology.”

Discovery of key molecular step which allows cancer cells to move to different parts of the body

Researchers at The University of Texas M. D. Anderson Cancer Center have figured out a key molecular step by which a cancer cell can unhook itself from the mesh weave of other cancer cells in a tumor, and move away to a different part of the body - the process, known as metastasis, that makes cancer so dangerous.

New link in the growth of Ewing’s sarcoma

To develop new therapeutic approaches to cancer, it is essential to understand the long and extremely complex process that underlies it, in other words the various stages of cancer development from the initial mutation to the tumor.

Tarceva plus Gemcitabine improves survival compared to Gemcitabine alone

OSI Pharmaceuticals, Inc., Genentech, Inc., and Roche announced today that results from a randomized Phase III clinical study of the investigational drug Tarceva (erlotinib HCl), in combination with gemcitabine chemotherapy met its primary endpoint of improving survival.

Researchers have discovered a possible way to distinguish lethal from localized prostate cancers

If future studies show their test -- measuring the level of activity of a signaling pathway called Hedgehog -- can predict which prostate cancers will spread, the results could revolutionize decision making processes for prostate cancer patients, the researchers say.
