Scientists at MIT create backpacks for cells which deliver chemotherapy agents

MIT engineers have outfitted cells with tiny "backpacks" that could allow them to deliver chemotherapy agents, diagnose tumors or become building blocks for tissue engineering.

How RNA polymerase kick starts gene activation revealed

How 'molecular machines' inside cells swing into action to activate genes at different times in a cell's life is revealed in new research published in Molecular Cell.

Age is not an independent factor in cancer survival rates, but clinical trials exclude older patients

Age is not an independent factor in cancer survival rates and should not influence decisions about how to treat older patients, according to a study in the November issue of IJCP, the Independent Journal of Clinical Practice.

Newly discovered protein may help explain tuberculosis' resiliency

Weill Cornell scientists have located a protein produced by the tuberculosis bacterium that may tell researchers more about how the invader lives so resiliently inside of the body.

Therapy targeting cyclin D1 protein may block expansion of breast cancer cells

Breast cancer stem cells are known to be involved in therapy resistance and the recurrence of cancerous tumors.

New research sheds light on key trigger of embryonic stem cell differentiation

Clusters of mouse embryonic stem cells called embryoid bodies more closely approximate true embryos in organization and structure than previously thought, according to researchers at the Stanford University School of Medicine.

Scientists identify compounds for stem-cell production from adult cells

In the study, the scientists screened known drugs and identified small molecules that could replace conventional reprogramming genes, which can have dangerous side effects.

Proteomics provides clues to how tuberculosis thwarts the immune system

A link between the immune system and the self-cleaning system by which biological cells rid themselves of obsolete or toxic parts may one day yield new weapons in the fight against tuberculosis and other deadly infectious diseases.

H5N1 protein hides in tiny tubules

A protein found in the virulent avian influenza virus strain called H5N1 forms tiny tubules in which it "hides" the pieces of double-stranded RNA formed during viral infection, which otherwise would prompt an antiviral immune response from infected cells, said Baylor College of Medicine researchers in an online report in the journal Nature.

New therapeutic target for inflammatory disorders

Researchers at Hospital for Special Surgery have identified a potential new therapeutic target that could be used to treat inflammatory disorders, such as rheumatoid arthritis.

Discover of gene behind specific language impairment

Scientists have identified the first gene that is associated with a common childhood language disorder, known as specific language impairment (SLI).

Discovery explains how insulin prompts fat and muscle cells to absorb glucose

A PhD student at Sydney's Garvan Institute of Medical Research has uncovered an important piece in the puzzle of how insulin works, a problem that has plagued researchers for more than 50 years.

Nicotinamide, a form of vitamin B3, reduces Alzheimer's symptoms

An over-the-counter vitamin in high doses prevented memory loss in mice with Alzheimer's disease, and UC Irvine scientists now are conducting a clinical trial to determine its effect in humans.

Scientists show how body regulates mature B-cells levels

Researchers at the University of Pennsylvania School of Medicine can now explain how the body determines whether there are enough mature B-cells in the blood stream at any one time.

Maternal obesity can program fetal brain to induce adult-onset obesity

Researchers at the University at Buffalo have found that fetuses of obese mother rats were programmed in utero to develop obesity in adulthood.

Lung airway cells activate vitamin D and increase immune response

Vitamin D is essential to good health but needs to be activated to function properly in the human body.

Resveratrol type drug mimics low-cal diet to ward off weight gain

A drug designed to specifically hit a protein linked to the life-extending benefits of a meager diet can essentially trick the body into believing food is scarce even when it isn't, suggests a new report in the November Cell Metabolism.

Apelin hormone shows promise as target for managing insulin resistance and type 2 diabetes

By injecting a hormone produced by fat and other tissues into mice, researchers report in the November Cell Metabolism that they significantly lowered blood sugar levels in normal and obese mice.
