Gene Expression News and Research

RSS

Gene Expression is the process by which a gene gets turned on in a cell to make RNA and proteins. Gene expression may be measured by looking at the RNA, or the protein made from the RNA, or what the protein does in a cell.

HDAC2 enzyme could be a potential target for new Alzheimer's drugs

MIT neuroscientists have shown that an enzyme overproduced in the brains of Alzheimer's patients creates a blockade that shuts off genes necessary to form new memories. Furthermore, by inhibiting that enzyme in mice, the researchers were able to reverse Alzheimer's symptoms.

MGH scientists isolate OSCs from ovaries of reproductive age women

For the first time, Massachusetts General Hospital (MGH) researchers have isolated egg-producing stem cells from the ovaries of reproductive age women and shown these cells can produce what appear to be normal egg cells or oocytes.

Study evaluates how environmental triggers might alter epigenetics of CFS

A University of Toronto Scarborough (UTSC) researcher is examining how environmental triggers might alter gene function in people with Chronic Fatigue Syndrome. The research could lead to better insights into the disease and eventually to new treatments.

Study aims to develop noninvasive method to analyze interstitial cystitis

A pilot study led by University of Kentucky researchers shows that the gene expression analysis of urine sediment could provide a noninvasive way to analyze interstitial cystitis in some patients.

Researchers discover how mTOR protein leads to cancer metastasis

Uncovering the network of genes regulated by a crucial molecule involved in cancer called mTOR, which controls protein production inside cells, researchers at the University of California, San Francisco (UCSF) have discovered how a protein "master regulator" goes awry, leading to metastasis, the fatal step of cancer.

FDA grants orphan-drug designation to Arno's AR-42 for treatment of meningioma, schwannoma

Arno Therapeutics, Inc. announced today that its investigational compound, AR-42, has been granted orphan-drug designation by the U.S. Food and Drug Administration for the treatment of meningioma and schwannoma of the central nervous system.

Telomerase reactivation in malignant cells after genomic instability causes cancer progression

Inhibiting telomerase, an enzyme that rescues malignant cells from destruction by extending the protective caps on the ends of chromosomes, kills tumor cells but also triggers resistance pathways that allow cancer to survive and spread, scientists report in the Feb. 17 issue of Cell.

Scientists discover molecular pathway by which maternally inherited deafness appears to occur

Yale scientists have discovered the molecular pathway by which maternally inherited deafness appears to occur: Mitochondrial DNA mutations trigger a signaling cascade, resulting in programmed cell death.

Researchers sequence genome of Tasmanian devil contagious cancer

Researchers have sequenced the genome of a contagious cancer that is threatening the Tasmanian devil, the world's largest carnivorous marsupial, with extinction. Cataloguing the mutations present in the cancer has led to clues about where the cancer came from and how it became contagious.

New preclinical data from Regulus' miR-21 study on kidney fibrosis

Regulus Therapeutics Inc., a biopharmaceutical company leading the discovery and development of innovative medicines targeting microRNAs, today announced that new preclinical data investigating the role of microRNA-21 (miR-21) in the treatment of kidney fibrosis has been published in the journal Science Translational Medicine.

New genetic resource to accelerate development of novel treatments for diseases

A new genetic resource from an international research consortium is expected to accelerate the development of new cures and treatments for a wide range of human diseases. This project, called the mouse "Collaborative Cross" (CC) resource, will increase the likelihood that experiments conducted in mice will advance our understanding of human biology.

Exposure to common flame retardant may affect fertility and long-term memory

Mice genetically engineered to be susceptible to autism-like behaviors that were exposed to a common flame retardant were less fertile and their offspring were smaller, less sociable and demonstrated marked deficits in learning and long-term memory when compared with the offspring of normal unexposed mice, a study by researchers at UC Davis has found.

Complex computer program helps analyze RNA structural motifs

Computer engineers may have just provided the medical community a new way of figuring out exactly how one of the three building blocks of life forms and functions.

Ovarian cancer subtype may be susceptible to 'anti-angiogenic' drugs

Scientists at Dana-Farber Cancer Institute have identified a subtype of ovarian cancer able to build its own blood vessels, suggesting that such tumors might be especially susceptible to "anti-angiogenic" drugs that block blood vessel formation.

mRNA sequencing reveals transcriptomic landscape of breast cancer

GW Cancer Research Team in the Department of Biochemistry and Molecular Biology, in the School of Medicine and Health Sciences, published a study that is the first of its kind to use mRNA sequencing to look at the expression of genome, at a unprecedented resolution at the current time, in three types of breast cancer.

Researchers discover a startling feature of early brain development

Researchers at the Salk Institute have discovered a startling feature of early brain development that helps to explain how complex neuron wiring patterns are programmed using just a handful of critical genes. The findings, published February 3 in Cell, may help scientists develop new therapies for neurological disorders, such as amyotrophic lateral sclerosis (ALS), and provide insight into certain cancers.

Researchers discover function and expression of CD97 in malignant gliomas

Researchers at Virginia Commonwealth University Medical Center's VCU Massey Cancer Center and Harold F. Young Neurosurgical Center and Old Dominion University have discovered that suppression of Wilms tumor 1 protein (WT1) results in downregulation of CD97 gene expression in three glioblastoma cell lines and reduces the characteristic invasiveness exhibited by glial tumor cells.

Scientists study organ development in mice to unravel how breast cancers develop in people

Reviving a theory first proposed in the late 1800s that the development of organs in the normal embryo and the development of cancers are related, scientists at the Salk Institute for Biological Studies have studied organ development in mice to unravel how breast cancers, and perhaps other cancers, develop in people. Their findings provide new ways to predict and personalize the diagnosis and treatment of cancer.
