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.

Protein DNA repair complex key to avoiding DNA repair mistakes

As the body creates antibodies to fight invaders, a three-protein DNA repair complex called MRN is crucial for a normal gene-shuffling process to proceed properly, University of Michigan research shows.

Epicept files NDA for Ceplene in Canada

EpiCept Corporation has announced that it has filed a New Drug Submission (NDS) with Health Canada for Ceplene® (histamine dihydrochloride) for the treatment of acute myeloid leukemia (AML) patients in first complete remission. Health Canada typically accepts or refuses an NDS and designates review status within forty-five days of filing. If accepted, the customary timeframe for completion of review and an approval decision is within one year.

New understanding on Gleevec's limitations

University of Michigan researchers have developed an animal model that provides strong evidence why imatinib, marketed as Gleevec, helps patients with chronic myeloid leukemia survive longer, but does not keep the disease from returning if treatment ends.

Silenced genes provide warning sign of blood cancer

In many types of cancer, parts of the genetic material of tumor cells are switched off by chemical labels called methyl groups. This kind of methyl labeling ranges among the epigenetic changes that do not change the sequence of DNA building blocks. Such labels are found particularly often in genes which act as important inhibitors of pathogenic cell growth.

Discovery of novel tumor suppressor

La Jolla Institute for Allergy & Immunology researchers studying an enzyme believed to play a role in allergy onset, instead have discovered its previously unknown role as a tumor suppressor that may be important in myeloproliferative diseases and some types of lymphoma and leukemia. Myeloproliferative diseases are a group of disorders characterized by an overproduction of blood cells by the bone marrow and include chronic myeloid leukemia. Lymphoma and leukemia are cancers of the blood.

Scientists re-engineer human enzyme to become resistant to harmful agents such as chemotherapy

Scientists from the Université de Montréal and McGill University have re-engineered a human enzyme, a protein that accelerates chemical reactions within the human body, to become highly resistant to harmful agents such as chemotherapy, according to a new study published in The Journal of Biological Chemistry.

Expert says the benefits of breastfeeding are oversold

Michael Kramer, a professor of pediatrics says that much of the evidence used to persuade mothers to breastfeed was either wrong or out of date.

Targeted nanoparticles boost arsenic’s anticancer punch

Arsenic trioxide has a long history as a potent human poison, but it also has proven valuable as one of the primary treatment options for acute promyelocytic leukemia. Efforts to use arsenic trioxide to treat other types of cancer are under way, but clinical trials are revealing that the extreme toxicity of this material is likely to limit its utility as a broad-spectrum anticancer agent.

Tamoxifen kills fungus cells and may prevent them from causing disease

An FDA-approved drug used for preventing recurrence of breast cancer shows promise in fighting life-threatening fungal infections common in immune-compromised patients, such as infants born prematurely and patients with cancer. Some scientists suspected that tamoxifen has antifungal properties; now new research from the University of Rochester Medical Center shows that it actually kills fungus cells and stops them from causing disease.

Childhood cancer risk rises with mother's age

Research from the Masonic Cancer Center, University of Minnesota indicates that a baby born to an older mother may have a slightly increased risk for many of the cancers that occur during childhood.

New insight into apoptosis

A study by Nanyang Technological University (NTU)'s Assistant Professor Li Hoi Yeung, Assistant Professor Koh Cheng Gee and their team have made an important contribution to the understanding of the process that cells go through when they die. This process known as 'apoptosis' or programmed cell death, is a normal process in the human body which removes perhaps a million cells a second.

Embryonic stem cells used to create human sperm

Human sperm have been created using embryonic stem cells for the first time in a scientific development which will lead researchers to a better understanding of the causes of infertility.

Thiarabine shows promise for rheumatoid arthritis

Access Pharmaceuticals, Inc. announced today new preclinical data demonstrating that thiarabine shows remarkable efficacy in the prevention and treatment of rheumatoid arthritis (RA).

Potential new target for acute myeloid leukemia

Dr. John Dick, Senior Scientist at the Ontario Cancer Institute, the research arm of Princess Margaret Hospital, co-led a multinational team that has developed the first leukemia therapy that targets a protein, CD123, on the surface of cancer stem cells that drive acute myeloid leukemia (AML), which is an aggressive disease with a poor outcome.

Survivors of childhood cancer at greater risk of birth complications when pregnant

Survivors of childhood cancer run particular risks when pregnant and should be closely monitored, the 25th annual conference of the European Society of Human Reproduction and Embryology heard this week.

Vegetarians less likely to develop cancer than meat eaters

Vegetarians are 12 per cent less likely to develop cancer than meat eaters, according to new research published in the British Journal of Cancer.

Epigenetic modulation at birth - altered DNA-methylation in white blood cells after Caesarean section

Swedish researchers have discovered that babies born by Caesarean section experience changes to the DNA pool in their white blood cells, which could be connected to altered stress levels during this method of delivery, according to the July issue of Acta Paediatrica.

Harnessing nanoparticles to track cancer cell changes

The more dots there are, the more accurate a picture you get when you connect them. Cancer researchers adopting that philosophy have developed a new imaging technology that could give scientists the ability to simultaneously measure as many as 100 or more distinct features in or on a single cell. In a disease such as cancer, that capability would provide a much better picture of what is going on in individual tumor cells.

Woman's placenta new source for harvesting stem cells

A groundbreaking study conducted by Children's Hospital & Research Center Oakland is the first to reveal a new avenue for harvesting stem cells from a woman's placenta, or more specifically the discarded placentas of healthy newborns.
