How does a heart know when it's big enough?

A protein discovered in fruit fly eyes has brought a Johns Hopkins team closer to understanding how the human heart and other organs automatically "right size" themselves, a piece of information that may hold clues to controlling cancer.

Study on zebrafish regenerate tissues links human heart implications

In a paper published in the March 25, 2010 issue of Nature, researchers working at the Salk Institute for Biological Studies and the Center of Regenerative Medicine in Barcelona (CMRB) identified a fish heart cell population that is the source of this astonishing healing feat, a finding that could provide insight into how mammalian hearts might be coaxed into repairing themselves after injury brought on by heart attack.

Novel ways of killing TB causing bacteria discovered

Researchers at Albert Einstein College of Medicine of Yeshiva University have found two novel ways of killing the bacteria that cause tuberculosis (TB), a disease responsible for an estimated two million deaths each year. The findings, published in the March 21 online issue of Nature Chemical Biology, could lead to a potent TB therapy that would also prevent resistant TB strains from developing.

Interfering with dickkopf 1 protein may help in controlling inflammatory bowel diseases

Signals released by immune cells during a bout of inflammatory bowel disease interfere with intestinal cells' ability to regenerate. Yet people with inflammatory bowel diseases have a significantly higher risk of developing colon cancer: a hyper-activation of growth in those same intestinal cells.

Workings of IGFs on muscle cells

The muscle-building abilities of hormones known as insulin-like growth factors (IGFs) are legendary. Just do an online search and you'll find not only scientific papers discussing the effects of IGFs on the cells that give rise to muscle tissue, but also scores of ads touting the purported benefits of IGF supplements for bodybuilding.

Mathematical model may promote medical research on how to grow new organs

Each cusp of our teeth is regulated by genes which carefully control the development. A similar genetic puzzle also regulates the differentiation of our other organs and of all living organisms.

Childhood stress and trauma may accelerate cellular aging

Children who suffer physical or emotional abuse could be faced with accelerated cellular aging as adults, according to new research published by Elsevier in Biological Psychiatry.

Researchers discover microtentacles that play key role in spreading cancer to distant locations in body

Researchers at the University of Maryland Marlene and Stewart Greenebaum Cancer Center have discovered that "microtentacles," or extensions of the plasma membrane of breast cancer cells, appear to play a key role in how cancers spread to distant locations in the body. Targeting these microtentacles might prove to be a new way to prevent or slow the growth of these secondary cancers, the scientists say.

Common diabetes therapies may increase cancer risk, but more research needed

The benefits of using insulin to treat diabetes far outweigh the risks, but a review just published online by IJCP, the International Journal of Clinical Practice, suggests that commonly used diabetes therapies may differ from each other when it comes to their influence on cancer risk.

Gene research offers new hope for targeted breast cancer treatment

CANCER RESEARCH UK scientists have developed a system to identify faulty or missing genes that could prevent specific chemotherapy regimes from working. This opens the doors for targeted breast cancer treatment, according to research published in the Lancet Oncology* today (Monday).

Researchers figure out how ATP molecule broken down in cells

Researchers at the Louisiana State University Health Sciences Center have figured out how ATP is broken down in cells, providing for the first time a clear picture of the key reaction that allows cells in all living things to function and flourish.

DNA interval in unexplored region of human genome increases risk for coronary artery disease

Scientists from the U.S. Department of Energy's Lawrence Berkeley National Laboratory have learned how an interval of DNA in an unexplored region of the human genome increases the risk for coronary artery disease, the leading cause of death worldwide.

Scientists develop new mathematical model to understand CML better

Doctors can now understand better chronic myeloid leukaemia (CML), including how it responds to therapy, thanks to a new mathematical model for the disease, developed by scientists in Portugal, Belgium and the United States. The work, to be published in the June edition of the journal Haematologica, also reveals that current therapies - which are not believed to cure CML - with the right protocol can actually get rid of the disease, and provides guidelines on how to do that.

Ways of stem cells division linked to development of cancer

Changes in the way that stem cells divide in the gut could lead to cancer, according to a new study funded by the Bobby Moore Fund for Cancer Research UK.

Kinesin protein motor shuttles cargo within cells and helps cells divide by rocking like a seesaw

Life's smallest motor, a protein that shuttles cargo within cells and helps cells divide, does so by rocking up and down like a seesaw, according to research conducted by scientists at the U.S. Department of Energy's Lawrence Berkeley National Laboratory and Brandeis University.

ATM tumor-suppressor also recognizes damage caused by ROS and orders autophagy

ATM, a protein that reacts to DNA damage by ordering repairs or the suicide of the defective cell, plays a similar, previously unknown role in response to oxidative damage outside of the nucleus, researchers report this week in the online version of the Proceedings of the National Academy of Sciences.

UWM engineer creates software program that foresees outcome before stem cell divides

A software program created by an engineer at the University of Wisconsin-Milwaukee (UWM) can not only predict the types of specialized cells a stem cell will produce, but also foresee the outcome before the stem cell even divides.

4SC AG announces the first treatment in Phase I clinical study of 4SC-205

4SC AG a drug discovery and development company focused on autoimmune and cancer indications, today announced the first treatment in a Phase I study evaluating 4SC-205, an oral Eg5 kinesin spindle protein inhibitor, in patients with solid tumours or malignant lymphomas.

Study shows cellular circuitry is more complex than previously thought

Using an elaborate sleuthing system they developed to probe how cells manage their own division, Johns Hopkins scientists have discovered that common but hard-to-see sugar switches are partly in control.
