Scientists demonstrate link between cancer and faulty differentiation of stem cells

Stem cells hold great promise for the medicine of the future, but they can also be a cause of disease. When these self-renewing, unspecialized cells fail to differentiate into diverse cell types, they can start dividing uncontrollably, leading to cancer. Already several decades ago, Weizmann Institute scientists were among the first to demonstrate the link between cancer and the faulty differentiation of stem cells. Now a new Weizmann Institute-led study, published in Molecular Cell, reveals a potential molecular mechanism behind this link.

Six young scientists to receive 2012 Klerman and Freedman Awards

Six young scientists will be recognized with the Annual Klerman and Freedman Awards by the Brain & Behavior Research Foundation on Friday July 27, 2012 at Le Parker Meriden Hotel in New York City on Friday, July 27.

Combination of Dox with MCP shows promise against prostate cancer

Doxorubicin (Dox) is an effective anti-cancer drug, but it's also a very toxic one, causing severe heart and immune damage. The doses needed to impact tumors are not well tolerated by patients, however, researchers may have found an answer through combination therapy.

Researchers discover mechanism that favours disappearance and inhibition of SCC development

Skin squamous cell carcinoma (SCC) is a subtype of very aggressive skin cancers that usually develops in sunexposed body regions, but can also affect a large number of organs such as the bladder, esophagus, lungs etc. However, little is known about the biology of these cells, which consequently makes difficult the generation of new specific therapies; actually, the standard treatments are based on surgery and subsequent radiotherapy.

Toxins and cell death: Interview with Professor Denise Montell

There are multiple kinds of cell death. Cells can undergo programmed cell death, which is a series of events that undergoes a predictable order at certain times during development.

Scientists discover new signalling pathway that controls both obesity and atherosclerosis

A*STAR scientists from the Institute of Molecular and Cell Biology (IMCB) and the Singapore Bioimaging Consortium (SBIC) have discovered a new signalling pathway that controls both obesity and atherosclerosis.

Abnormal bone marrow stem cells drive development of myelodysplastic syndromes

Researchers at Albert Einstein College of Medicine of Yeshiva University have found that abnormal bone marrow stem cells drive the development of myelodysplastic syndromes (MDS), serious blood diseases that are common among the elderly and that can progress to acute leukemia. The findings could lead to targeted therapies against MDS and prevent MDS-related cancers. The study is published today in the online edition of the journal Blood.

3D printed templates of filament networks can improve function of engineered living tissues

Researchers are hopeful that new advances in tissue engineering and regenerative medicine could one day make a replacement liver from a patient's own cells, or animal muscle tissue that could be cut into steaks without ever being inside a cow.

RUB biologists deliberately transform spinal cord stem cells into immature nerve cells

RUB biologists have deliberately transformed stem cells from the spinal cord of mice into immature nerve cells. This was achieved by changing the cellular environment, known as the extracellular matrix, using the substance sodium chlorate.

Protein kinase A activated in the nucleus as well as the cytoplasm

Using a new tool allowing proteins in a living cell to be manipulated in real time, researchers at Johns Hopkins have stumbled across the answer to a longstanding debate about where and how a certain protein is turned on in the cell. Reporting in the February 2012 issue of Nature Chemical Biology, scientists show that protein kinase A is also activated in the nucleus rather than inside the cell’s body, a challenge to traditional beliefs.

Grb2 switch controls normal signaling through fibroblast growth factor receptor

Once considered merely a passive link between proteins that matter, Grb2 - pronounced "grab2" - actually lives up to its nickname with its controlling grip on an important cell signaling pathway, scientists at The University of Texas MD Anderson Cancer Center report in the June 22 issue of Cell.

Tinkering with p190RhoGAP molecule shapes development of cardiac stem cells

Johns Hopkins researchers have discovered that a single protein molecule may hold the key to turning cardiac stem cells into blood vessels or muscle tissue, a finding that may lead to better ways to treat heart attack patients.

Researchers can silence mutated gene responsible for Huntington's with single drug treatment

With a single drug treatment, researchers at the Ludwig Institute for Cancer Research at the University of California, San Diego School of Medicine can silence the mutated gene responsible for Huntington's disease, slowing and partially reversing progression of the fatal neurodegenerative disorder in animal models.

Research examines link between metabolic syndrome and cognitive disorders

No effective treatments are currently available for the prevention or cure of Alzheimer's disease (AD), the most frequent form of dementia in the elderly. The most recognized risk factors, advancing age and having the apolipoprotein E Ɛ4 gene, cannot be modified or treated. Increasingly, scientists are looking toward other risk factors to identify preventive and therapeutic strategies.
