Researchers explain molecular mechanism that induces HER2+ tumours to ignore cell signals

About 30% of breast cancer patients have tumours that show rapid growth and invasion through the body. A common denominator in all of these cases is the presence of a large number of Her2 proteins in tumour cellular membranes. Consequently, these aggressive tumours are referred to as HER2+. Scientists working in the Metastasis Laboratory (MetLab) at IRB Barcelona headed by ICREA researcher Roger Gomis, have described the molecular mechanism that induces HER2+ tumours to ignore the signals that protect cells from excessive growth.

Blocking miR-375 microRNA in ERalha-positive breast cancer cells slows down cancer cell growth

Two thirds of breast cancers are ERalpha-positive, i.e., many estrogen receptors of the ERalpha- type are found in their cells. "These molecules can interact with the estrogen hormone and, thus, even lead to cancer," explains Dr. Joerg Hoheisel; molecular biologist at DKFZ. "The connection between the levels of the estrogen receptor alpha and the occurrence of breast cancer has been known for some time now.

DFG announces establishment of eleven new Collaborative Research Centres

The Deutsche Forschungsgemeinschaft (DFG, German Research Foundation) will establish eleven new Collaborative Research Centres (CRC) as of 1 January 2011. This decision was made recently by the responsible Grants Committee at its autumn meeting in Bonn. The new CRCs will receive a total of - 94.4 million (including a 20 percent programme allowance for indirect project costs) for an initial funding period of four years.

Researchers identify trigger mechanism for quality control checkpoint in cell division process

Researchers from Huntsman Cancer Institute (HCI) at the University of Utah report that they have identified a previously undiscovered trigger mechanism for a quality control checkpoint at the very end of the cell division process in a paper to be published in the November 29 issue of The Journal of Cell Biology and online today.

Study finds cancer cells subject to several major chromosomal changes at the same time

New progress has been made on the road to understanding the origins of genetic changes in tumour cells. The prevalent theory has been that genetic changes in tumour cells come about in multiple stages over a long time. However, a recent study by researchers at Lund University shows that this does not have to be the case at all, but that the cancer cells instead can be subject to several major chromosomal changes at the same time.

Johns Hopkins scientists identify protein mechanism that regulates cell division

By tracking the flow of information in a cell preparing to split, Johns Hopkins scientists have identified a protein mechanism that coordinates and regulates the dynamics of shape change necessary for division of a single cell into two daughter cells.

New antibody with SGN-35 drug produces remission in Hodgkin lymphoma

An antibody loaded with an anti-cancer agent produced complete or partial remissions in 38 percent of patients with relapsed or therapy-resistant Hodgkin lymphoma enrolled in a phase I clinical trial, investigators report in the Nov. 4 issue of the New England Journal of Medicine.

Researchers find link between telomere length and colorectal cancer risk

For the first time, researchers have found a link between long telomeres and an increased risk for colorectal cancer, according to research presented at the American Association for Cancer Research special conference on Colorectal Cancer Biology to Therapy, held here Oct. 27-30, 2010.

NCRR awards 450 Recovery Act instrumentation grants to NIH-funded scientists

Leading-edge, shared technologies are an important component of advancing research to improve health. Specialized instruments such as high-powered electron microscopes, high-resolution mass spectrometers and supercomputers that rapidly process vast amounts of data can enable breakthrough discoveries in preventions, treatments and cures for diseases.

Researchers use fruit fly for cancer research

SMALL and with a life cycle of just two weeks, fruit flies are seen by many as pests and a problem all year round. However, for nearly a century, the humble insect, officially known as Drosophila melanogaster, which measures no more than 3mm, has performed a vital role in genetics and developmental biology.Fruit flies are genetically diverse and easy to use in research, helping scientists in a variety of studies, from how the brain functions to how cancer develops.

Study suggests epoD; microtubule-stabilizing drugs may treat neurodegenerative diseases

Finding a drug that can cross the blood-brain barrier is the bane of drug development for Alzheimer's disease and other neurological disorders of the brain. A new Penn study, published this week in the Journal of Neuroscience, has found and tested in an animal model of Alzheimer's disease a class of drug that is able to enter the brain, where it stabilizes degenerating neurons and improves memory and learning.

ACS awards Research Scholar Grant to Rensselaer researcher for breast cancer study

A recent Research Scholar Grant from the American Cancer Society acknowledges the potential of Rensselaer researcher Lee Ligon's work on breast cancer. Ligon is investigating interactions between cells as breast cancer spreads within the body.

Scientists identify mechanism that regulate nuclear size

Size matters when it comes to the nucleus of a cell, and now scientists have discovered the signals that control how big the nucleus gets. Nuclear size varies not only among different species, but also in different types of cells in the same species and at different times during development. In addition, cancer cells are known to develop larger nuclei as they become more malignant. Screening for cervical cancer, for example, involves looking for grossly distorted nuclei in cervical cells collected during a Pap smear.
