Leukemia News and Research

RSS

Leukemia (Leukaemia) is a cancer of the blood cells. It is the most common type of blood cancer and affects 10 times as many adults as children. Most people diagnosed with leukemia are over 50 years old. No one knows why some people develop leukemia and others do not. However, scientists have identified some risk factors for the disease. Most people who have known risk factors do not get leukemia, while many who do get the disease have none of these risk factors. During the early stages of leukemia, there may be no symptoms. Many of the symptoms of leukemia don't become apparent until a large number of normal blood cells are crowded out by leukemia cells.

Lack of insurance coverage driving up number of patients who seek dental care in the emergency room

More Americans are turning to the emergency room for routine dental problems - a choice that often costs 10 times more than preventive care and offers far fewer treatment options than a dentist's office, according to an analysis of government data and dental research.

Pfizer responds to CDC’S ACIP discussion related to use of Prevnar 13 in adults over 50

Pfizer Inc. issued the following statement in response to today's discussion by the Centers for Disease Control and Prevention's (CDC) Advisory Committee on Immunization Practices (ACIP) regarding the use of Prevnar 13 (Pneumococcal 13-valent Conjugate Vaccine)in adults 50 years of age and older.

FDA, pharmaceutical companies announce solution to cancer drug shortage

The U.S. Food and Drug Administration and several pharmaceutical companies said Tuesday they have reached agreements to alleviate shortages for the drugs methotrexate and Doxil. Methotrexate is used to treat children with a form of leukemia and others with tumors of the breast and lungs. Doxil is used to treat ovarian cancer and multiple myeloma.

Researchers discover how mTOR protein leads to cancer metastasis

Uncovering the network of genes regulated by a crucial molecule involved in cancer called mTOR, which controls protein production inside cells, researchers at the University of California, San Francisco (UCSF) have discovered how a protein "master regulator" goes awry, leading to metastasis, the fatal step of cancer.

FDA approves new supplies of drugs that are facing shortages

The United States Food and Drugs Administration (FDA) have approved new suppliers for two crucial cancer drugs, easing critical shortages that had been concerning patients and families particularly of the children with leukemia. But there are currently 283 separate prescription drugs in short supply or unavailable nationwide, and regulators and manufacturers say shortages are a long-term problem that will continue to scare patients and doctors.

Telomerase reactivation in malignant cells after genomic instability causes cancer progression

Inhibiting telomerase, an enzyme that rescues malignant cells from destruction by extending the protective caps on the ends of chromosomes, kills tumor cells but also triggers resistance pathways that allow cancer to survive and spread, scientists report in the Feb. 17 issue of Cell.

DNA ‘nanorobot’ effectively targets cancer leaving healthy cells untouched: Study

Researchers have developed ‘nano-sized’ probes built from DNA that can seek and destroy cancer cells, leaving healthy cells untouched. These ‘nanorobots’ release their drug payload only when they reach and identify their target and are believed to improve many treatments for disease.

Modified imatinib cancer drug prevents morphine tolerance in rats

By reformulating the common cancer drug imatinib (Gleevec), researchers have eliminated morphine tolerance in rats - an important step toward improving the effectiveness of chronic pain management in patients, according to researchers at The University of Texas MD Anderson Cancer Center.

NASDAQ notifies CytRx of non-compliance with minimum bid price requirement

CytRx Corporation, a biopharmaceutical company specializing in oncology, today announced that, as anticipated, on February 15, 2012, the Company was notified by The NASDAQ Stock Market that because the Company has not regained compliance with the $1.00 minimum bid price requirement under NASDAQ Listing Rule 5550(a)(2), the Company's common stock would be subject to delisting from The NASDAQ Capital Market unless the Company requests a hearing before a NASDAQ Hearings Panel.

Study reveals immune mechanism for surveillance over EBV infection

Some 90 percent of people are exposed to the Epstein Barr virus (EBV) at some point in their life. Even though it is quickly cleared from the body, the virus can linger silently for years in small numbers of infected B cells.

Study reveals new guiding principles for cancer genomics

That our chromosomes can break and reshuffle pieces of themselves is nothing new; scientists have recognized this for decades, especially in cancer cells. The rules for where chromosomes are likely to break and how the broken pieces come together are only just now starting to come into view.

Shortage looming, drug maker agrees to release emergency supplies of kids' cancer drug

A shortage of a drug used to treat children's cancer seems to have been averted for a time as the Food and Drug Administration says it reached an agreement with the drug supplier to release emergency supplies. Elsewhere, rules sometimes force hospitals to throw away scarce drugs.

Study: 3D organization of chromosomes plays a role in cancer genomics

It is well understood that chromosomal translocation - a process whereby pieces of two chromosomes break off and exchange places - is a hallmark of many cancers including leukemia, thyroid cancer and lymphoma and play an important part in how healthy cells become cancerous. The role spatial proximity plays in why certain chromosomal translocations happen repeatedly, however, has been a long-standing area of debate among scientists.

Biochemists determine first crystal structure of an immunoproteasome

Like a shredder, the immunoproteasome cuts down proteins into peptides that are subsequently presented on the cellular surface. The immune system can distinguish between self and nonself peptides and selectively kills cells that due to a viral infection present non-self peptides at their surface. In autoimmune diseases this mechanism is deregulated and the immune system also eliminates uninfected cells by mistake.

Researchers test nanoscale carbon clusters for cancer chemotherapy

A mixture of current drugs and carbon nanoparticles shows potential to enhance treatment for head-and-neck cancers, especially when combined with radiation therapy, according to new research by Rice University and the University of Texas MD Anderson Cancer Center.
