Adult offspring of parents with PTSD have lower cortisol levels

A small study suggests that adults whose parents are Holocaust survivors with post-traumatic stress disorder (PTSD) appear to have lower average levels of the stress hormone cortisol than the adult offspring of parents without PTSD, according to a report in the September issue of Archives of General Psychiatry, one of the JAMA/Archives journals.

New clue to mechanisms of gene signaling and regulation

Scientists have discovered a pattern in the DNA sequence of the mouse genome that may play a fundamental part in the way DNA molecules regulate gene expression.

Pharmion and MethylGene announce orphan drug designation for treatment of Hodgkin's lymphoma

Pharmion Corporation, along with its collaborator MethylGene Inc., today announced that the U.S. Food and Drug Administration (FDA) has designated the Companies' histone deacetylase (HDAC) inhibitor, MGCD0103, as an Orphan Drug for the treatment of Hodgkin's lymphoma in the United States.

Reactivating a critical gene lost in kidney cancer reduces tumor growth

Researchers at Mayo Clinic Jacksonville, have found that a key gene is often silenced in clear cell renal cell carcinoma, the most common type of kidney cancer, and when they restored that gene in human kidney cancer cells in culture and animal experiments, tumors stopped growing and many disappeared.

Plasmodium falciparum is responsible for the most severe forms of human malaria.

Folic acid protects againts exposure to bisphenol A in the womb

Experiments in animals have provided additional and tantalizing evidence that what a pregnant mother eats can make her offspring more susceptible to disease later in life.

Effects of aging hematopoietic stem cells

There is little disagreement that the body's maintenance and repair systems deteriorate with age, even as there is plenty of disagreement as to why.

Protein IKKa protects checkpoint gene from chemical shutdown

A protein that is largely absent in one type of skin cancer protects an important gene in a cell's defense against harmful mutations from being silenced, researchers at The University of Texas M. D. Anderson Cancer Center report in the July 20 edition of Molecular Cell.

True nature of heterochromatin revealed

Not so long ago, the difficult-to-sequence, highly repetitive, gene-poor DNA found in regions of chromosomes known as heterochromatin was called "junk." Like dark matter in the universe, the true nature of heterochromatin was unknown.

The unexpected connection of two gene regulation mechanisms points to new ways for the fight against leukemia

When the activity of individual genes it is longer required, there are two main mechanisms responsible for the “switching off”, mainly DNA methylation and the Polycomb protein complex. Sometimes, these mechanisms lose their efficiency and some of the genes that should be "switched off" remain active.

Embryonic stem cells can be created without eggs

Embryonic stem cells are unique because they can develop into virtually any kind of tissue type, an attribute called pluripotency.

Reprogrammed fibroblasts resemble embryonic stem cells

Stem cell biology takes another exciting leap forward as scientists report that normal tissue cells can be reprogrammed to exhibit many of the properties that are characteristic of embryonic stem cells, including the ability to give rise to multiple cell types and contribute to the germline.
