Big leap in genomic screening of blood vessels from patient tissue

Scientists have developed a new method of capturing a complete genome-wide screening of blood vessel cells in their actual disease state, advancing the potential for genetic research on the tissue responsible for delivering nourishment that can accelerate the growth of both a cancer tumor or wound healing.

St. Jude discovers factors that accelerate resistance to Gleevec targeted therapy in lymphoblastic leukemia

Results of a study by investigators at St. Jude Children's Research Hospital provide strong evidence for why the drug imatinib (Gleevec), which has revolutionized the treatment of chronic myelogenous leukemia (CML), is often unable to prevent relapse of a particularly aggressive form of acute lymphoblastic leukemia (ALL).

Evolution may have sped up

Is heading straight for a goal the quickest way there? If the name of the game is evolution, suggests new research at the Weizmann Institute of Science, the pace might speed up if the goals themselves change continuously.

Scientists reveal the actions of a key player in colorectal cancer

Colorectal cancer is one of the most prevalent cancers in the Western world. The tumor starts off as a polyp but then turns into an invasive and violent cancer, which often spreads to the liver.

Blocking angiogenesis signaling from inside cell may lead to serious health problems

Angiogenesis inhibitors that block a tumor's development of an independent blood supply have been touted as effective cancer fighters that result in fewer side effects than traditional chemotherapy.

Nanoparticle drug delivery system for brain tumor therapy shows promise

A nanoparticle drug delivery system designed for brain tumor therapy has shown promising tumor cell selectivity in a novel cell culture model devised by University of Nottingham scientists.

All eukaryotic kinases share 1 common set of substrates

Kinase mediated phosphorylation is generally recognised as the major regulator of virtually all metabolic activities in eukaryotic cells including proliferation, gene expression, motility, vesicular transport and programmed cell death.

New clues to why persistent acid reflux can turn into cancer

New research from scientists at UT Southwestern Medical Center and the Dallas Veterans Affairs Medical Center underscores the importance of preventing recurring acid reflux while also uncovering tantalizing clues on how typical acid reflux can turn potentially cancerous.

FGFR4 gene plays a complex role in obesity, fatty liver and diabetes

Researchers at the Texas A&M Health Science Center Institute of Biosciences and Technology at Houston have found that a gene in the liver and elsewhere in the body, when inhibited or increased, affects fatty liver and diabetes but does not alleviate both diseases at once.

Scientists find mechanisms controlling metastasis of breast cancer cells

When cancer cells dissociate from the original tumor and migrate via the blood stream to colonize distant organs, is the main cause of cancer death.

Scientists produce functioning neurons from human embryonic stem cells

Scientists with the Institute of Stem Cell Biology and Medicine at UCLA were able to produce from human embryonic stem cells a highly pure, large quantity of functioning neurons that will allow them to create models of and study diseases such as Alzheimer's, Parkinson's, prefrontal dementia and schizophrenia.
