Method to count the absolute number of individual protein molecules inside a living cell

Yale researchers have reported a method to count the absolute number of individual protein molecules inside a living cell, and to measure accurately where they are located, two basic hurdles for studying biology quantitatively.

Discovery of a new kind of messenger RNA molecule

Researchers at Cold Spring Harbor Laboratory have discovered a new kind of messenger RNA molecule that is converted from non-protein coding status to protein coding status in response to cellular stress such as viral infection.

Spliceosome crucial for processing non-coding RNA

The discovery in 1977 that the coding regions of a gene could appear in separate segments along the DNA won the 1993 Nobel Prize in Physiology or Medicine for Richard J. Roberts and Phillip A. Sharp. The active segments of a gene were termed exons, separated from each other within the gene by inactive introns.

"Junk" DNA not important to an organism's evolutionary survival

Genetic material derisively called "junk" DNA because it does not contain the instructions for protein-coding genes and appears to have little or no function is actually critically important to an organism's evolutionary survival, according to a study conducted by a biologist at the University of California, San Diego.

Research reveals possible mechanisms for the treatment of cocaine addiction

Researchers are now understanding in greater detail the molecular machinery underlying the short-term brain changes that produce the high of cocaine, as well as the longer-term changes behind addiction. Their findings offer hope for targeted drugs that can short-circuit that addiction machinery.

Identification of a single chromosome region linked to specific language impairment

Researchers at the University of Toronto (U of T), Capital Health's Stollery Children's Hospital in Edmonton, Toronto's Hospital for Sick Children and their international collaborators have discovered a genetic abnormality that causes a type of language impairment in children

Access to genetic counseling and testing are an important part of cancer control

Ten years after the identification of the first breast cancer susceptibility genes so few high-risk minority women have received genetic counseling or testing that the standard methods of calculating risk have not been validated in these groups and the results of genetic testing can still produce surprises.

Data supports use of personal and family history of breast cancer, ovarian cancer, or both in making clinical decisions

African American women at high-risk of breast cancer have genetic mutations that would make genetic testing feasible, according to a study in the October 19 issue of JAMA: The Journal of the American Medical Association.

Newly discovered role of MECP2 gene in Rett Syndrome

Huda Zoghbi, of Baylor College of Medicine and the Howard Hughes Medical Institute and Juan Young, also of Baylor and colleagues report in the online Early Edition of the Proceedings of the National Academy of Science, posted the week of October 17, 2005, that the Rett Syndrome gene, MECP2, regulates RNA splicing.

New genetic discovery may help explain why some people develop high blood pressure and others don't

It also gives new insight into how the kidneys govern the balance of salt in the body, a crucial task for regulating blood pressure. And, it reveals how a gene already linked to behavior and mental health can play a role in the body, as well as the brain.

Significant step forward in the genome era

In what promises to be a significant step forward in the genome era, the National Human Genome Research Institute (NHGRI) today announced plans to devote a portion of its large-scale sequencing capacity to efforts aimed at identifying the genetic roots of specific diseases that have long eluded gene hunters.

WWOX gene finding could lead to a new strategy for treating lung cancer

The research focused on a gene known as WWOX, which is lost or silenced in a large majority of lung cancers, and in cancers of the breast, ovary, prostate, bladder, esophagus and pancreas. The work was led by scientists at The Ohio State University Comprehensive Cancer Center - Arthur G. James Cancer Hospital and Richard J. Solove Research Institute.

New treatment for the pediatric eye cancer retinoblastoma

Investigators at St. Jude Children's Research Hospital have demonstrated in laboratory studies a new treatment for the pediatric eye cancer retinoblastoma that appears to be more effective than the current standard therapy, and more likely to prevent the recurrence of this cancer. A report on their work appears in the October 15 issue of Clinical Cancer Research.

Rett syndrome discovery

The gene responsible for Rett syndrome, a devastating neurological disease found mostly in girls, not only silences some genes but in combination with another also regulates alternative splicing, crucial to the formation of proteins -- a finding that may explain the symptoms associated with this puzzling disorder and others related to it

New findings on brain tumors called ependymomas

Brain tumors called ependymomas that occur in different parts of the central nervous system appear to arise from subpopulations of stem cells called radial glia cells (RGCs), according to investigators at St. Jude Children's Research Hospital. The discovery explains why some identical-looking ependymomas are actually distinctly different diseases, the researchers said.

Tourette syndrome linked to SLITRK1 gene

Tourette syndrome is a distressing condition which affects one in every 100 people.

Ethnic differences in cardiovascular risk factors

Heredity plays a major role in determining the blood lipid profile and heart rate variability of blacks and whites, two major risk factors for coronary artery disease, researchers say.

E-cadherin, that cellular touch so important in cancer

E-cadherin is a molecule involved in adhesion between epithelial cells that also seems to have a protective role in cancer, since its loss is associated with tumour progression and metastases formation in a series of different cancers.

Discovery of agent that can suppress cancer development

In a case of basic science detective work, researchers at The University of Texas M. D. Anderson Cancer Center have solved the puzzle of the "inconsistent biomarker" and, in the process, may have discovered an agent that can suppress cancer development.

First gene mutation associated with Tourette syndrome

Researchers have identified the first gene mutation associated with Tourette syndrome - opening a new avenue for understanding the complex disorder that causes muscle and vocal tics.
