Dye derived from Canary Island lichens may help treat Alzheimer's disease

A red dye derived from lichens that has been used for centuries to color fabrics and food appears to reduce the abundance of small toxic protein aggregates in Alzheimer's disease. The dye, a compound called orcein, and a related substance, called O4, bind preferentially to small amyloid aggregates that are considered to be toxic and cause neuronal dysfunction and memory impairment in Alzheimer's disease.

Promising new agent against sarcomas affecting children

MK 1775, a small, selective inhibitor molecule, has been found to be active against many sarcomas when tested by researchers at Moffitt Cancer Center in Tampa, Fla. Their findings, recently appearing in Molecular Cancer Therapeutics, published by the American Association for Cancer Research, suggest that a badly needed new agent against sarcomas - especially sarcomas affecting children - may be at hand.

NIAAA awards Rutgers $10M grant to explore genetic links to alcoholism

Rutgers University Cell and DNA Repository (RUCDR) has received a $10 million grant from the National Institute on Alcohol Abuse and Alcoholism (NIAAA) to provide DNA extraction, basic genetic testing, and repository services for more than 46,000 saliva samples, in support of national research efforts to determine the genetic and environmental factors that lead to alcoholism.

First study of cortisol awakening response in infants

Cortisol may be the Swiss Army knife of hormones in the human body -- just when scientists think they understand what it does, another function pops up. While many of these functions are understood for adults, much less is known about how cortisol operates in babies and toddlers, especially when it comes to an important phenomenon called the cortisol awakening response, or CAR.

Blocking telomerase increases cancer cells' sensitivity to radiation treatment

Shortening end caps on chromosomes in human cervical cancer cells disrupts DNA repair signaling, increases the cells' sensitivity to radiation treatment and kills them more quickly, according to a study in Cancer Prevention Research.

First results from whole-genome sequencing clinical trial on triple negative breast cancer

Triple negative breast tumors, which make up nearly 20 percent of breast cancers, do not respond to treatment with targeted therapies such as Herceptin-(trastuzumab).

Established human embryonic cell lines vary from newly derived stem cell lines

Established human embryonic cell lines, including those approved for federal research funding under former President George W. Bush, are different than newly derived human embryonic stem cell lines, according to a study by UCLA stem cell researchers.

Northwestern researchers receive NIAMSD grant to study scleroderma

Northwestern Medicine researchers have received two five-year grants totaling $953,000 from the National Institutes of Health's (NIH) National Institute of Arthritis and Musculoskeletal and Skin Diseases to study scleroderma, an autoimmune disease for which there currently is no cure.

New method reveals complete set of aberrant signaling pathways that give rise to cancers

One major obstacle in the fight against cancer is that anticancer drugs often affect normal cells in addition to tumor cells, resulting in significant side effects. Yet research into development of less harmful treatments geared toward the targeting of specific cancer-causing mechanisms is hampered by lack of knowledge of the molecular pathways that drive cancers in individual patients.

Specific electromagnetic fields can block cancer cell growth

New evidence by University of Alabama at Birmingham researchers that specific electromagnetic fields can safely block the proliferation of cancer cells and tumor growth may help refine a new, targeted therapy without any collateral damage.

Researchers discover how distant satellite cells could help repair damaged muscles

When a muscle is damaged, dormant adult stem cells called satellite cells are signaled to "wake up" and contribute to repairing the muscle. University of Missouri researchers recently found how even distant satellite cells could help with the repair, and are now learning how the stem cells travel within the tissue.

Researchers identify cancer cell mitochondria as 'Achilles' heel' of tumor growth

Researchers at the Kimmel Cancer Center at Jefferson have identified cancer cell mitochondria as the unsuspecting powerhouse and "Achilles' heel" of tumor growth, opening up the door for new therapeutic targets in breast cancer and other tumor types.

Life as a couch potato can create new fat in fat cells

Conventional wisdom says that exercise is a key to weight loss - a no-brainer. But now, Tel Aviv University researchers are revealing that life as a couch potato, stretched out in front of the TV, can actually be "active inactivity" - and cause you to pack on the pounds.
