Ribonucleic acid (RNA) is a biologically important type of molecule that consists of a long chain of nucleotide units. Each nucleotide consists of a nitrogenous base, a ribose sugar, and a phosphate.

Hope against dangerous form of acute lymphoblastic leukemia

After an intensive three-year hunt through the genome, medical researchers have pinpointed mutations that leads to drug resistance and relapse in the most common type of childhood cancer-the first time anyone has linked the disease's reemergence to specific genetic anomalies.

Cells lose ability to defend against transposons as they age

Even in our DNA there is no refuge from rogues that prey on the elderly. Parasitic strands of genetic material called transposable elements - transposons - lurk in our chromosomes, poised to wreak genomic havoc. Cells have evolved ways to defend themselves, but in a new study, Brown University researchers describe how cells lose this ability as they age, possibly resulting in a decline in their function and health.

Brandeis University researchers to receive Wiley Prize in Biomedical Sciences

Deborah E. Wiley, Chair of The Wiley Foundation, John Wiley & Sons, Inc., announced today that the twelfth annual Wiley Prize in Biomedical Sciences will be awarded to Dr. Michael Young, Rockefeller University, Dr. Jeffrey Hall, Brandeis University (Emeritus), and Dr. Michael Rosbash, Brandeis University.

Endothelial cells can trigger changes in cancer cells without direct contact

Blood vessels that supply oxygen and nutrients to tumors can also deliver something else - a signal that strengthens nearby cancer cells, making them more resistant to chemotherapy, more likely to spread to other organs and more lethal, scientists at The University of Texas MD Anderson Cancer Center report online in Cancer Cell.

Bioelectric signals can identify cells that are likely to develop into tumors

Biologists at Tufts University School of Arts and Sciences have discovered a bioelectric signal that can identify cells that are likely to develop into tumors. The researchers also found that they could lower the incidence of cancerous cells by manipulating the electrical charge across cells' membranes.

Study demonstrates new fragile genomic sites responsible for chromosomal alterations in tumors

Cancer arises from the accumulation of mutations and structural changes in chromosomes, which in some cases give rise to combinations that favour the growth or expansion of the disease. In this context, chromosomes tend to lose or duplicate entire regions, although, the mechanisms that initiate these chromosomal abnormalities are not fully understood.

SINEUP allows scientists to target individual genes in cells to increase protein production

One of the most innovative biotechnologies of the last decade has recently been developed. SINEUP allows scientists, for the first time, to target individual genes in cells to knockup, or increase, the amount of protein they make. The technique will improve Protein manufacture, analyse the function of genes and engineer improved cell function.

Interrupting key interaction between p68 and calcium-calmodulin inhibits cancer metastasis

Disrupting a key interaction between two types of proteins in cells inhibits the spread of cancerous cells, providing researchers with a new pathway toward developing cancer-fighting drugs, according to new findings by Georgia State University scientists.

Clarient adopts QIAGEN’s therascreen KRAS test to diagnose colorectal cancer

QIAGEN N.V. today announced that Clarient - a GE Healthcare Company and leading provider of cancer laboratory testing services in the United States - has adopted the use of the therascreen KRAS RGQ PCR Kit (therascreen KRAS test) as a companion diagnostic to guide the use of Erbitux (cetuximab) as a treatment in patients with metastatic colorectal cancer.

FBH1 gene helps turn up the effect of chemotherapy

Chemotherapy is one of the most common treatments for cancer patients. However, many patients suffer from serious side-effects and a large proportion does not respond to the treatment. Researchers from the Biotech Research and Innovation Centre (BRIC) and Center for Healthy Aging, University of Copenhagen, now show that the gene FBH1 helps turn up the effect of chemotherapy.

Non-coding RNA essential for normal embryonic cardiogenesis

Many different tissues and organs form from pluripotent stem cells during embryonic development. To date it had been known that these processes are controlled by transcription factors for specific tissues. Scientists from the Max Planck Institute for Molecular Genetics in Berlin, in collaboration with colleagues at MIT and the Broad Institute in Boston, have now been able to demonstrate that RNA molecules, which do not act as templates for protein synthesis, participate in these processes as well.

U-M researchers develop new method thet could enhance gene sequencing data

When researchers sequence the RNA of cancer cells, they can compare it to normal cells and see where there is more RNA. That can help lead them to the gene or protein that might be triggering the cancer.

Scientists identify genetic process in which normal liver cells transform into cancerous ones

A team of scientists from the Cancer Science Institute of Singapore (CSI) at the National University of Singapore (NUS) has identified a genetic process in which normal liver cells transform into cancerous ones. The finding provides new understanding into the pathogenesis of human cancers.

New DNA-delivering film holds promise for improving effectiveness of vaccines

Vaccines usually consist of inactivated viruses that prompt the immune system to remember the invader and launch a strong defense if it later encounters the real thing. However, this approach can be too risky with certain viruses, including HIV.

Gilead commences first of two tenofovir alafenamide Phase 3 trials in HIV

Gilead Sciences, Inc. today announced the initiation of the first of two Phase 3 clinical trials (Study 104) evaluating a single tablet regimen containing tenofovir alafenamide (TAF) for the treatment of HIV-1 infection in treatment-naïve adults.

New study may help treat patients with multiple myeloma

A study led by Robert G. Hawley, Ph.D., professor and chair of the department of anatomy and regenerative biology at the George Washington University (GW) School of Medicine and Health Sciences (SMHS), may help predict which patients with multiple myeloma will respond better to certain treatments.

Researchers discover safe and efficient way to get large molecules through the cell membrane

Living cells are surrounded by a membrane that tightly regulates what gets in and out of the cell. This barrier is necessary for cells to control their internal environment, but it makes it more difficult for scientists to deliver large molecules such as nanoparticles for imaging, or proteins that can reprogram them into pluripotent stem cells.

Normalizing p62 protein levels in immune system cells could reduce infection in CF patients

New research suggests that lowering excessive levels of a protein in immune system cells could be a strategy to clear an infection that is deadly to patients with cystic fibrosis (CF).
