Novel approach to kill acute lymphoblastic leukemia cells

Nora Heisterkamp, PhD, and Reshmi Parameswaran, PhD, of The Saban Research Institute of Children's Hospital Los Angeles, have found a novel approach to killing acute lymphoblastic leukemia (ALL) cells. Using a fusion toxin that specifically targets cancer cells, this novel therapeutic may offer a future alternative to patients who become resistant to chemotherapy.

ARI-4175 drug may treat colorectal cancer patients with KRAS mutation

When combined with other treatments, the drug cetuximab-which works by slowing or stopping the growth of cancer cells-has been shown to extend survival in certain types of cancer, including metastatic colorectal cancers. Unfortunately, about 40 percent of colorectal cancer patients-specifically those who carry a mutated form of a gene called KRAS-do not respond to the drug. Researchers at Fox Chase Cancer Center in Philadelphia, however, have been working on a way to overcome this resistance to cetuximab by unleashing a second cetuximab driven mechanism using a novel drug called ARI-4175.

VCAM1 nanobodies can effectively visualize atherosclerotic lesions

In collaboration with a Brussels University team under the leadership of Nick Devoogdt and a French team from INSERM, Serge Muyldermans and his team, associated with VIB and Vrije Universiteit Brussel, have succeeded in developing the first patient-friendly, non-invasive method for differentiating dangerous strictures in blood vessels, so-called vulnerable atherosclerotic plaques, from less dangerous ones.

UV light-activated on-off switch for Morpholinos

University of Oregon scientists collaborating with an Oregon company that synthesizes antisense Morpholinos for genetic research have developed a UV light-activated on-off switch for the vital gene-blocking molecule. Based on initial testing in zebra-fish embryos, the enhanced molecule promises to deliver new insights for developmental biologists and brain researchers.

Study assesses link between antifolate medications, KRAS mutations and amplification

Testing patients with non-small cell lung cancer for both mutations and amplifications of the KRAS gene prior to therapy may help to predict response to treatment with antifolates, according to the updated results of a preclinical study presented at the AACR Annual Meeting 2012, held here March 31 - April 4.

Crizotinib reduces testosterone levels in men with ALK positive lung cancer

Men experience a marked drop in their testosterone levels when taking a targeted therapy to control a specific type of lung cancer. That's according to a University of Colorado Cancer Center study published in the April issue of Cancer, the official journal of the American Cancer Society.

CHD8, SNC2A and KATNAL2 gene mutations lead to ASDs

Mutations in three new genes have been linked to autism, according to new studies including one with investigators at Mount Sinai School of Medicine. All three studies include lead investigators of the Autism Sequencing Consortium.

Piceatannol blocks preadipocytes’ ability to develop and grow

A compound found in red wine, grapes and other fruits, and similar in structure to resveratrol, is able to block cellular processes that allow fat cells to develop, opening a door to a potential method to control obesity, according to a Purdue University study.

New cell and animal model of IBC

Inflammatory breast cancer (IBC) is a very aggressive, often misunderstood type of cancer that is diagnosed more frequently in younger women compared with other types of breast cancer. The five-year survival rate is between 25 and 50 percent-significantly lower than the survival rate for other types of breast cancer. The reason for the poor prognosis is that IBC usually grows rapidly and often spreads quickly to other parts of the body, including the brain, bone and lymph nodes.

Fathers more likely to transmit spontaneous mutations to children with ASDs

Researchers have turned up a new clue to the workings of a possible environmental factor in autism spectrum disorders (ASDs): fathers were four times more likely than mothers to transmit tiny, spontaneous mutations to their children with the disorders. Moreover, the number of such transmitted genetic glitches increased with paternal age. The discovery may help to explain earlier evidence linking autism risk to older fathers.

Scientists image process of consciousness after general anesthesia

Awakening from anesthesia is often associated with an initial phase of delirious struggle before the full restoration of awareness and orientation to one's surroundings. Scientists now know why this may occur: primitive consciousness emerges first. Using brain imaging techniques in healthy volunteers, a team of scientists led by Adjunct Professor Harry Scheinin, M.D. from the University of Turku, Turku, Finland in collaboration with investigators from the University of California, Irvine, USA, have now imaged the process of returning consciousness after general anesthesia.

Scientists uncover structure and operating mechanism of TPPII

Uncontrolled or inaccurate degradation of cellular proteins can lead to diseases like cancer or Alzheimer's disease. Scientists of the Max Planck Institute of Biochemistry (MPIB) in Martinsried near Munich, Germany, have now uncovered the structure and the operating mechanism of an important component of the human cellular degradation machinery, tripeptidyl peptidase II.

Scripps Florida scientists to create new screening tests for HCV treatment discovery

Scientists from the Florida campus of The Scripps Research Institute have been awarded just over $1 million from the National Institutes of Health for a three-year study to develop new high-throughput screening tests to find compounds that disable a protein essential to hepatitis C virus (HCV) replication.

µ-PIIIA conotoxin can be effective in controlling cancer pain

Hidden in the mud, the cone snail Conus purpurascens lies in wait for its victims. It attracts its prey, fish, with its proboscis, which can move like a worm, protruding from the mud. Once a fish approaches out of curiosity, the snail will rapidly shoot a harpoon at it, which consists of an evolutionarily modified tooth. The paralyzed victim then becomes an easy meal. It takes the venomous cone snail about two weeks to digest a fish. During this time, its venomous harpoon is also replaced.
