Using acidity to detect cancer

Normally, tissues demonstrate a slightly acidic intracellular pH (pHi) and slightly alkaline extracellular pH (pHe). However, proliferating tissues demonstrate transient pH Gradient Reversal i.e. alkalinization of pHi and acidification of pHe.

Salk Institute scientists find new target for glioblastoma multiforme treatment

Glioblastoma multiforme is a particularly deadly cancer. A person diagnosed with this type of brain tumor typically survives 15 months, if given the best care. The late Senator Ted Kennedy succumbed to this disease in just over a year.

DNA damage may lead to mutation and changes in cell

A team of researchers from Colorado State University has been studying DNA damage in living cells to learn more about how genetic abnormalities arise. It has long been known that DNA molecules in every cell get constantly damaged by things from the outside environment, like sunlight, cigarette smoke and radiation. However, more recently researchers have discovered that sources from within the cell itself can sometimes be even more damaging.

UNC researchers uncover new potential strategy to kill cancerous cells in the brain

Rapidly dividing cells rely on an enzyme called Dicer to help them repair the DNA damage that occurs as they make mistakes in copying their genetic material over and over for new cells. UNC Lineberger Comprehensive Cancer Center researchers have built on the discovery of Dicer's role in fixing DNA damage to uncover a new potential strategy to kill rapidly dividing, cancerous cells in the brain.

E-cigarettes damage cells in ways that could lead to cancer

Adding to growing evidence on the possible health risks of electronic cigarettes, a lab team at the Veterans Affairs San Diego Healthcare System tested two products and found they damaged cells in ways that could lead to cancer. The damage occurred even with nicotine-free versions of the products.

Researchers identify new gene that helps maintain chromosome number in cells

Molecular biologists at UT Southwestern Medical Center have identified a gene called NORAD that helps maintain the proper number of chromosomes in cells, and that when inactivated, causes the number of chromosomes in a cell to become unstable, a key feature of cancer cells.

New discovery may soon make prostate cancer cells easier to destroy

A newly discovered connection between two common prostate cancer treatments may soon make prostate cancer cells easier to destroy. Drugs that could capitalize on the discovery are already in the pipeline, and a clinical trial to test whether the finding could improve treatments for prostate cancer patients could be only a few years away.

Cancer drug may protect kidneys from damage caused by chemotherapy agent cisplatin

A class of drugs used increasingly to help fight cancer may have the additional benefit of protecting the kidneys when packaged with the powerful chemotherapy agent cisplatin.

TET proteins needed to maintain genome instability, say researchers

Members of the TET (short for ten-eleven translocation) family have been known to function as tumor suppressors for many years, but how they keep a lid on the uncontrolled cell proliferation of cancer cells had remained uncertain. Now, researchers at the La Jolla Institute for Allergy and Immunology demonstrate that TET proteins collectively constitute a major class of tumor suppressors and are required to maintain genome instability.

Low levels of BRCA1 protein in the brain linked to dementia

Mutant forms of breast cancer factor 1 (BRCA1) are associated with breast and ovarian cancers but according to new findings, in the brain the normal BRCA1 gene product may also be linked to Alzheimer's disease. The results, published in Nature Communications, suggest that low levels of BRCA1 protein in the brain may contribute to dementia.

BRCA1 depletion can potentially contribute to cognitive deficits in Alzheimer's disease

Researchers from the Gladstone Institutes have shown for the first time that the protein BRCA1 is required for normal learning and memory and is depleted by Alzheimer's disease.

University of Kansas professor recognized with MERIT Award

Emily Scott, professor of medicinal chemistry at the University of Kansas, has been recognized with a MERIT Award from the National Institutes of Health's National Institute of General Medical Sciences. It's a rare and important recognition -- researchers can receive them only once in a career.

Study reports discovery of new class of DNA repair enzyme

This year's Nobel Prize in chemistry was given to three scientists who each focused on one piece of the DNA repair puzzle. Now a new study, reported online Oct. 28 in the journal Nature, reports the discovery of a new class of DNA repair enzyme.

Certain drugs could be used to treat gastric cancers with particular pattern of mutations

Gastric cancer, otherwise known as stomach cancer, does not respond well to existing treatments and it is currently the third leading cause of cancer death in the world (after lung and liver cancer). Researchers have discovered that certain drugs, currently used to treat breast, ovarian and pancreatic cancers, could also be used to treat certain gastric cancers with a particular pattern of mutations (genomic molecular fingerprint).

DNA study reveals basic principle of gene regulation

A study of where and how an enzyme cuts DNA may have inadvertently revealed a basic principle of gene regulation, say researchers in Boston Children's Hospital's Program in Cellular and Molecular Medicine (PCMM).

Ground-breaking discovery helps scientists view DNA damage with crystal clarity

Scientists have developed a new technique for looking at the initial steps of DNA oxidation – a process which can lead to DNA damage, mutations and cancers. The breakthrough, which uses DNA in crystals, should help related research in the fields of cancer medicine and drug development.
