New MIT study implicates RNA-binding proteins in regulation of cancer

A new study from MIT implicates a family of RNA-binding proteins in the regulation of cancer, particularly in a subtype of breast cancer. These proteins, known as Musashi proteins, can force cells into a state associated with increased proliferation.

Findings open new avenues for research to predict risk of therapy-related AML

For a small percentage of cancer patients, treatment aimed at curing the disease leads to a form of leukemia with a poor prognosis. Conventional thinking goes that chemotherapy and radiation therapy induce a barrage of damaging genetic mutations that kill cancer cells yet inadvertently spur the development of acute myeloid leukemia (AML), a blood cancer.

Researchers identify biochemical mechanism that could lead to 'chemo brain'

UNC School of Medicine researchers have found for the first time a biochemical mechanism that could be a cause of "chemo brain" - the neurological side effects such as memory loss, confusion, difficulty thinking, and trouble concentrating that many cancer patients experience while on chemotherapy to treat tumors in other parts of the body.

Protein that regulates the body's sleep cycle may offer cancer protection

People who work around the clock could actually be setting themselves back, according to Virginia Tech biologists.

Commonly used osteoporosis medications may also prevent lung, breast and colon cancers

The most commonly used medications for osteoporosis worldwide, bisphosphonates, may also prevent certain kinds of lung, breast and colon cancers, according to two studies led by researchers at the Icahn School of Medicine at Mount Sinai and published today in the Proceedings of the National Academy of Sciences.

Researchers uncover easily detectable, 'pre-malignant' state in the blood

Researchers from the Broad Institute of MIT and Harvard, Harvard Medical School, and Harvard-affiliated hospitals have uncovered an easily detectable, "pre-malignant" state in the blood that significantly increases the likelihood that an individual will go on to develop blood cancers such as leukemia, lymphoma, or myelodysplastic syndrome.

Rice University researchers model dynamic instability of microtubules

New computer models that show how microtubules age are the first to match experimental results and help explain the dynamic processes behind an essential component of every living cell, according to Rice University scientists.

Study identifies genetic alterations that contribute to growth and recurrence of Ewing sarcoma

An international collaboration has identified frequent mutations in two genes that often occur together in Ewing sarcoma (EWS) and that define a subtype of the cancer associated with reduced survival.

First steps in the origin of pancreatic cancer identified by Mayo Clinic researchers

Researchers at Mayo Clinic's campus in Jacksonville say they have identified first steps in the origin of pancreatic cancer and that their findings suggest preventive strategies to explore.

New automaton model simulates various scenarios of tumor growth

Cancer constantly wages war on the human body. Battles are won, lost or sometimes end in a stalemate. In pancreatic cancer, this stalemate—known as tumor dormancy—can last up to 25 years before becoming aggressively malignant, a phenomena that is poorly understood.

Hormone loss may cause colon cancer, say Thomas Jefferson University researchers

Some cancers, like breast and prostate cancer, are driven by hormones such as estrogen and testosterone, but to date, there are none that are driven by the lack of a hormone. New evidence suggests that human colon cells may become cancerous when they lose the ability to produce a hormone that helps the cells maintain normal biology. If verified by further studies, it suggests that treating patients at high risk for colon cancer by replacing the hormone guanylin could prevent the development of cancer.

Four UCLA researchers receive NIH Director's New Innovator Award

Four scientists from the Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research at UCLA have received a National Institutes of Health Director's New Innovator Award that will forward revolutionary stem cell and neuro-science in medicine.

New study reveals mechanism that compromises chromosome stability

During cell division, chromosomes acquire a characteristic X-shape with the two DNA molecules (sister chromatids) linked at a central "connection region" that contains highly compacted DNA.

LLNL scientists issued patent for producing antimicrobial compounds to fight superbugs

Superbugs, antibiotic-resistant bacteria, have been on the rise since antibiotics were first introduced 80 years ago. That's because these germ-fighting agents have lost their punch from being overprescribed and misused, allowing bacteria pathogens to develop immunities against them.

Researchers uncover molecular interaction between key proteins in cell division

Researchers from Guillermo Montoya's team at the Spanish National Cancer Research Centre (CNIO), in collaboration with Isabelle Vernos' Group from the Centre for Genomic Regulation (CRG), have uncovered the molecular interaction between TACC3 and chTOG, key proteins in forming the internal cellular framework that enables and sustains cell division.

UMass Amherst cell biologists propose new detailed cytokinesis model

Along with copying and splitting DNA during division, cells must have a way to break safely into two viable daughter cells, a process called cytokinesis. But the molecular basis of how plant cells accomplish this without mistakes has been unclear for many years.

Research findings provide clues for design of future HIV vaccine

Scientists at The Scripps Research Institute have described how a single family of antibodies that broadly neutralizes different strains of HIV has evolved remarkably diverse structures to attack a vulnerable site on the virus.

Scientists identify gene mutation that causes aplastic anemia

An international team of scientists has identified a gene mutation that causes aplastic anemia, a serious blood disorder in which the bone marrow fails to produce normal amounts of blood cells.

MIT engineers find new strategy to combat superbugs

In recent years, new strains of bacteria have emerged that resist even the most powerful antibiotics. Each year, these superbugs, including drug-resistant forms of tuberculosis and staphylococcus, infect more than 2 million people nationwide, and kill at least 23,000. Despite the urgent need for new treatments, scientists have discovered very few new classes of antibiotics in the past decade.

Reproductive cell division has mechanical safeguard against chromosome sorting errors

Reproductive cell division has evolved a simple, mechanical solution to avoid chromosome sorting errors, researchers report in the Sept. 11 Science Express.
