Approved breast cancer drug offers hope for the treatment of blood disorders
A new study provides an explanation as to why blood cancers are more common in men than in women, revealing that estrogens regulate the survival of stem cells that give rise to blood cancers. Moreover, findings in mice with blood neoplasms suggest that a drug called tamoxifen, which targets estrogen receptors and is approved for treatment of breast cancer, may also be a valuable strategy for blocking the development of blood neoplasms in humans.

Mini chromosomes that strengthen tumors
Cancers are due to genetic aberrations in certain cells that gain the ability to divide indefinitely. This proliferation of sick cells generates tumors, which gradually invade healthy tissue. Therefore, current therapies essentially seek to destroy cancer cells to stop their proliferation.

Smoking and higher mortality in men
In a new study, published in Science, researchers at Uppsala University demonstrate an association between smoking and loss of the Y chromosome in blood cells. The researchers have previously shown that loss of the Y chromosome is linked to cancer. Since only men have the Y chromosome, these results might explain why smoking is a greater risk factor for cancer among men and, in the broader perspective, also why men in general have a shorter life expectancy.

Female sex hormones can protect against the development of some blood disorders
Estrogens, a major class of female sex hormone, can regulate the activity of the hematopoietic stem cells in the bone marrow and in this way influence the development of some types of leukemia. This is the conclusion of a new study led by researchers at the Centro Nacional de Investigaciones Cardiovasculares and published in the latest edition of the journal Cell Stem Cell.

Cons of regular low-dose aspirin to stave off serious illness in women outweigh pros

'Wound response' of cancer stem cells may explain chemo-resistance in bladder cancer
A novel mechanism -- similar to how normal tissue stem cells respond to wounding -- might explain why bladder cancer stem cells actively contribute to chemo-resistance after multiple cycles of chemotherapy drug treatment. Targeting this 'wound response' of cancer stem cells can potentially provide a novel approach for therapeutic invention, said researchers from the National Cancer Institute-designated Dan L. Duncan Cancer Center at Baylor College of Medicine.

Not all induced pluripotent stem cells are made equal: McMaster researchers
Human stem cells made from adult donor cells 'remember' where they came from and that's what they prefer to become again. This means the type of cell obtained from an individual patient to make pluripotent stem cells, determines what can be best done with them.

Cancer from asbestos caused by more than one cell mutation
It has been a long held belief that tumors arising from exposure to asbestos are caused by mutations in one cell, which then produces multiple clones. This hypothesis is challenged by new research published in the open-access Journal of Translational Medicine, which suggests it is caused by mutations in multiple cells.

Common prostate cancer treatment associated with decreased survival in older men
A common prostate cancer therapy should not be used in men whose cancer has not spread beyond the prostate, according to a new study led by researchers at Henry Ford Hospital. The findings are particularly important for men with longer life expectancies because the therapy exposes them to more adverse side effects, and it is associated with increased risk of death and deprives men of the opportunity for a cure by other methods.

Study examines use of drugs to strengthen bones for men receiving ADT
Although some guidelines recommend use of bisphosphonates, a class of drugs used to strengthen bone, for men on androgen deprivation therapy, an analysis finds that prescriptions for these drugs remains low, even for those men at high risk of subsequent fractures, according to a study in the Dec. 3 issue of JAMA.

Lung cancer risk model refines decisions to screen
A new method for determining lung cancer risk could more efficiently identify individuals for annual screening and catch more cancers early, according to a study published in this week's PLOS Medicine. The study, conducted by Martin Tammemägi of Brock University, Canada, and colleagues, evaluates a lung cancer risk prediction model and identifies a risk threshold for selecting individuals for annual lung cancer screening.

Prognostic role found for miR-21 expression in triple-negative breast cancer
'Triple-negative' breast cancer occurs in patients whose cells do not express receptors for estrogen, progesterone, and/or human epidermal growth factor receptor 2 (ER/PR/HER2). Because of the absence of these predictive biomarkers, treatment assignment can be difficult. Now, researchers report that high levels of the microRNA miR-21 in the tumor microenvironment, but not in the tumor epithelia, are associated with worse clinical outcomes for patients with triple-negative breast cancer, thus identifying a possible triple-negative breast cancer prognostic biomarker.
