Scientists discover molecular structure related to cell growth and cancer

Researchers discovered a special type of molecular structure that helps keep genes properly turned off until the structure is ejected from those genes in a regulated manner to help turn the genes on.

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.

Diabetes drugs may also prevent nerve degeneration caused by Alzheimer's disease

Recent research has shown a surprising link between Alzheimer’s and diabetes, two of the major health challenges facing society today. According to Dr Holscher modern lifestyle promotes the development of type 2 diabetes, which in turn could drastically increase the number of people to develop Alzheimer’s disease as people with type 2 diabetes are much more likely to develop the disease than healthy people of the same age.

Menin is a key player in the development of some forms of acute leukemia

Tumor-suppressor proteins work to inhibit tumor growth in our bodies and when they win, they spare us a battle with cancer. But one such protein, menin, appears to have a split personality.

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.

Diet rich in fruits and vegetables could be a good defense against prostate cancer

Previous studies have suggested that increased intake of flavonoids which are common in fruits and vegetables may be associated with a reduced risk of prostate cancer, according to Sanjay Gupta, Ph.D., an assistant professor in the Case School of Medicine Department of Urology.

Identification of a factor in human milk that can block HIV-1 transmission

Mother to child transmission of HIV accounts for a large proportion of HIV infections in children, with many infected as a result of breastfeeding, which requires transfer of the virus across mucosal barriers. DC-SIGN, a DC lectin receptor, interacts with HIV and is found at high expression levels in tonsillar tissue.

Breast cancer drug Herceptin a 'stunner'

According to the New England Journal of Medicine (NEJM) the first trials of the breast cancer drug, Herceptin, tested on women with early stage disease are "simply stunning".

"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.

Good news for treating children with amblyopia

New research findings led by Thomas Krahe and Ary S. Ramoa of Virginia Commonwealth University School of Medicine offer two pieces of good news for treating children with amblyopia.

Blocking macrophage migration inhibitory factor molecule might prevent the progression of multiple sclerosis

A new study suggests that a substance made by immune cells plays a key role in the progression of a disease in animals that closely mimics multiple sclerosis (MS). The findings further suggest that blocking the molecule, known as macrophage migration inhibitory factor (MIF) might prevent the progression of the disease.

Yearly PSA test saves lives

Men who have a yearly blood test to examine their prostate specific antigen levels are nearly three times less likely to die from prostate cancer than those who don't have annual screenings, according to a study presented October 19, 2005, at the American Society for Therapeutic Radiology and Oncology's 47th Annual Meeting in Denver.

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.

Herceptin results "quite remarkable"

The targeted drug trastuzumab, or Herceptin, previously shown to prolong survival in advanced breast cancer, dramatically reduced the chances of recurrence in patients with early-stage disease when given for one year following standard chemotherapy.

A DNA-based vaccine could be a potent weapon against bird flu

Researchers scrambling to combat a virulent form of bird flu that could mutate into a form easily spread among humans should consider developing vaccines based on DNA, according to British biochemical engineers.

Conjugated linoleic acid prevents inflammatory damage resulting from immune response

One of the isomers of conjugated linoleic acid, a group of fatty acids found in milk, is a natural regulator of the COX-2 protein, which plays a significant role in inflammatory disease such as arthritis and cancer, according to a study published by University of Wisconsin-Madison researchers.

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.

Yeast cells help show how GSAO (glutathionarsenoxide) angiogenesis inhibitor drug works

The humble yeast has revealed the molecular workings of an anti-cancer drug that stops the growth and spread of tumours in humans by starving their blood supply.

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.
