Computer predicts anti-cancer molecules

A new computer-based method of analyzing cellular activity has correctly predicted the anti-tumour activity of several molecules.

Human tumor nanoparticles induce apoptosis of pancreatic cancer cells

Using nanoparticles made from pieces of tumor cells, investigators from Aix-Marseille University in Marseille, France, have developed a new type of anticancer agent that appears to stop tumor cell growth and proliferation.

EntreMed receives new patent for 2-Methoxyestradiol analogs

EntreMed, Inc. has announced the issuance of U.S. Patent No. 7,371,741 covering analogs of 2- methoxyestradiol (2ME2).

Congressional Democrats move to impose new limits on specialty hospitals

The New York Times on Sunday examined how Democrats -- who for years "have been trying to stop the proliferation of doctor-owned hospitals in the belief that they drive up costs by encouraging doctors to order more procedures" -- have moved to "impose new restrictions on these for-profit hospitals" as part of a Senate supplemental war appropriations bill, although they have "carved out exemptions for a few institutions represented by influential senators and well-connected lobbyists."

MicroRNA play a significant role in some human cancers

A new study demonstrates that microRNAs can modulate the expression of well known tumor-specific oncogenic translocation proteins and may play a significant role in some human cancers. The research, published by Cell Press in the June issue of the journal Cancer Cell, is likely to lead to new strategies for treating some specific lymphomas and leukemias.

A genetic tool for cleaner water

A genetic tool used by medical researchers may also be used in a novel approach to remove harmful microbes and viruses from drinking water.

Chronic inflammation of the intestine or stomach damages DNA

Chronic inflammation of the intestine or stomach can damage DNA, increasing the risk of cancer, MIT scientists have confirmed.

Soil bacteria may offer potential treatments for MRSA and cancer

Big pharma gave up on soil bacteria as a source of antibiotics too soon, according to research published in the June issue of Microbiology. Scientists have been mining microbial genomes for new natural products that may have applications in the treatment of MRSA and cancer and have made some exciting discoveries.

Timer genes control brain size

Experiments using fruit flies have helped a team at the MRC National Institute for Medical Research to identify genes that control how large the developing brain becomes.

Regenerative medicine offers hope in spinal cord injury

Spinal cord injury (SCI) can be a catastrophic event for the individual. Traditionally, such injuries were viewed as permanent, irreversible neurological dysfunction, but over time research has shown some neuroplastic capability of the injured adult mammalian spinal cord. However, spontaneous functional recovery post-SCI is very modest.

Arsenic-based agent shown to help eradicate leukemia-initiating cells

In both leukemia and solid tumors, there exists among the multitude of warrior cancer cells a small subgroup that work undercover, patiently lying in wait to launch their attacks. Known as either cancer initiating cells (CICs) or leukemia initiating cells (LICs), these stealth populations are impervious to conventional chemotherapy and undaunted by targeted cancer therapies. When a leukemia patient relapses following a period of remission, it is the LICs that bear responsibility for the disease's reemergence.

New theory suggests how hepatitis C may cause rare immune disease

Of the hepatitis alphabet, the C variant may be the nastiest. In 1990, researchers observed that most patients with hepatitis C also develop a rare autoimmune disease called mixed cryoglobulinemia, a condition that frequently leads to cancer, arthritis or both.

Human cytomegalovirus mimics human protein to hijack cell division machinery

Viruses are masters of deception, duping their host's cells into helping them grow and spread. A new study has found that human cytomegalovirus (HCMV) can mimic a common regulatory protein to hijack normal cell growth machinery, disrupting a cell's primary anti-cancer mechanism.

Economic downturn prompts many nurses to work more shifts, helps address nursing shortage

The Wall Street Journal on Wednesday examined how the "ailing economy" has prompted many nurses to work additional shifts, delay retirement or return to the work force from retirement -- all of which have helped "ease the nursing shortage."

Epidermal growth factor receptor protects cancer cells from starving

A growth factor receptor found abundantly on the surface of cancer cells and long known to fuel cancer growth also protects tumor cells from starvation by a newly identified mechanism, researchers at The University of Texas M. D. Anderson Cancer Center report in the May 5 issue of Cancer Cell.

Small molecule nutlin-3a activates an important cancer suppressor gene

By activating a cancer suppressor gene, a small molecule called nutlin-3a can block cancer cell division, according to researchers at the National Cancer Institute (NCI), part of the National Institutes of Health.

Biomarker predicts malignancy potential of HG-PIN lesions in the prostate

Men whose prostate cancer screenings show high grade prostatic intraepithelial neoplasia (HG-PIN) may find themselves in limbo, "stuck" between diagnoses - they are told prostate cancer has not yet developed, but it might, and they are advised to undergo repeated needle biopsies as a precaution.

Research reveals the signature of 70 genes controlled by two microRNAs

By restoring two small molecules that are often lost in chronic leukemia, researchers were able to block tumor growth in an animal model.

Signalife awarded new U.S. patent for method to monitor heartbeats

Signalife, Inc. has announced that the United States Patent and Trademark Office has awarded the Company a new and important patent entitled "System For, And Method Of, Monitoring Heartbeats Of A Patient". The patent, which covers 37 claims, will enhance the Company's ability to develop new proprietary products.

Mechanism discovered that can send cells on the road to cancer

Using a common virus as a tool for investigating abnormal cell proliferation, a team led by scientists at Cold Spring Harbor Laboratory (CSHL) has succeeded in clarifying an intricate series of biochemical steps that shed light on a way that cancer can begin.
