Scientists gain new insights into how cancer cells may squeeze through narrow blood vessels

The spread of cancer from a tumor's original location to other parts of the body can play a major role in whether the disease turns deadly. Many steps in this process, called metastasis, remain murky.

Researchers determine how Ki-67 protein disperses chromosomes in dividing cells

Billions of your cells divide every day. Cell division fuels growth and also replaces short-lived cells in some organs, like your skin, blood, and gut.

Structures on surface of pneumococci determine bacteria’s ability to cause meningitis

Structures on the surface of pneumococci determine the ability of these bacteria to enter the brain and cause severe infections, according to a paper published in The Journal of Clinical Investigation by researchers at Karolinska Institutet.

Penn researchers help identify unique characteristics of reserve stem cells

Adult stem cells represent a sort of blank clay from which a myriad of different cell and tissue types are molded and as such are of critical importance to health, aging and disease.

B lymphocytes can influence psoriasis by regulating cytokine IL-10

"A pathological and very complex autoimmune reaction of the skin": This is the definition doctors and scientists use to describe psoriasis, a disease that affects one to three percent of the population.

OIST scientists reveal how big protein complex inside E. coli cells divide and multiply

Escherichia coli (E. coli) are bacteria that live all around and inside of us. Most E. coli are harmless, but some strains can cause illness, and can even, in extreme cases, be deadly. With recent outbreaks of E. coli around the world, there is a fear of acquiring an infection from these bacteria.

Drexel scientists identify how two new antimalarial drugs work

Drexel University scientists have discovered an unusual mechanism for how two new antimalarial drugs operate: They give the parasite's skin a boost in cholesterol, making it unable to traverse the narrow labyrinths of the human bloodstream.

Malicious form of ATF2 protein drives formation of melanoma

An international collaborative study led by scientists at the Sanford Burnham Prebys Medical Discovery Institute has identified a malicious form of a protein that drives the formation of melanoma.

Study examines effects of ultra-low doses of glyphosate on gene expression profiles

Glyphosate, often sold under the brand name of Roundup, is the world's most widely used weed-killer. While Glyphosate has approval from regulatory bodies worldwide, there are growing concerns about its possible adverse health effects.

Novel therapeutic approach to treat leukaemia patients

Cancer cells have an abnormal cell division and survival machinery - they grow faster than they die. For their permanent development, they produce an excess of growth factors and nutrients and block the body's own safety mechanisms.

Unlocking the dark proteome: an interview with Dr Kriwacki

The term dark proteome refers to proteins whose structural features and thus functions are not well understood. Many proteins within the dark proteome do not fold into stable three-dimensional structures. These proteins are called intrinsically disordered proteins (IDPs) and feature highly flexible, disordered confirmations.

New interactive radiation therapy planning system can help improve patient's chances of recovery

Radiation therapy is one of the most essential elements in cancer treatment. But properly planning radiation therapy is a highly complex task. Fraunhofer mathematicians have joined an alliance with medical physicists and physicians to improve the therapy planning process. In doing so they have helped improve patient's chances of recovery.

University of Glasgow-led study could lead to improved treatments for lymphoma, other cancers

A study by scientists at the University of Glasgow, which reveals the critical role a common cancer-associated gene plays in lymphoma development, could lead to improved treatments for a range of cancers.

Scientists develop new technology that helps visualize translation of mRNA into proteins

For the first time, scientists at Albert Einstein College of Medicine have developed a technology allowing them to "see" single molecules of messenger RNA as they are translated into proteins in living mammalian cells. Initial findings using this technology that may shed light on neurological diseases as well as cancer were published online today in Science.

Key protein involved in mitosis helps prevent abnormal distribution of chromosomes

A tension-sensitive "fail safe" protein helps make sure that when our cells divide the two resulting cells inherit the normal number of chromosomes, researchers from the University of Washington and the Fred Hutchinson Cancer Research Center report today, May 5, in the journal Cell.
