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.

Discovery of 'master regulator' gene for skin development

Researchers at Oregon State University have found one gene in the human body that appears to be a master regulator for skin development, in research that could help address everything from skin diseases such as eczema or psoriasis to the wrinkling of skin as people age.

Time (and PPAR-beta/delta) heals all wounds

Mammalian skin requires constant maintenance, but how do skin cells know when to proliferate and at what rate?

Stem cell therapy may lead to treatment for deafness

Deafness affects more than 250 million people worldwide. It typically involves the loss of sensory receptors, called hair cells, for their "tufts" of hair-like protrusions, and their associated neurons.

Molecular fingerprints point the way to earlier cancer diagnosis and more targeted treatment

Metabolites are molecular fingerprints of what your cells are up to and Dr. Arun Sreekumar wants to know the impression made by cancer.

New RNA-Seq technique used to profile anthrax genome

Scientists at the Georgia Institute of Technology have used a new approach, known as RNA-Seq, to profile the gene expression of the bacterium that causes anthrax, Bacillus anthracis.

Discovery of genetic markers for aggressive head and neck cancer

Scientists at Albert Einstein College of Medicine of Yeshiva University have identified genetic markers that signal poor outcomes for patients with head and neck cancer.

Epigenetic mark guides stem cells toward their destiny

Not all stem cells are completely blank slates. Some, known as adult stem cells, have already partially embraced their fates, and are capable of becoming only cells of a particular type of tissue.

Paradigm shift in the regulation of immune response

Over the past decade various pieces of the puzzle how signal transmission controls immunity have been coming together.

Epigenetic mark guides stem cells toward their destiny

Not all stem cells are completely blank slates. Some, known as adult stem cells, have already partially embraced their fates and are capable of becoming only cells of a particular type of tissue. So how do these tissue-specific stem cells restrict their fate?

MicroRNA undermines tumor suppression

Scientists at the Whitehead Institute for Biomedical Research and the National University of Singapore have discovered the first microRNA (miRNA) capable of directly tamping down the activity of the well known tumor-suppressor gene, p53, While p53 functions to prevent tumor formation, the p53 gene is thought to malfunction in more than 50% of cancerous tumors.

Frankincense oil may be an inexpensive alternative therapy for bladder cancer

Originating from Africa, India, and the Middle East, frankincense oil has been found to have many medicinal benefits.

Proteomics study shows that genes involved in invertebrate longevity have surprising parallels in humans

Prolexys Pharmaceuticals has announced the publication of the discovery of genes that are likely to have a role in the aging process of humans.

Prion discovery gives clue to control of mass gene expression

The discovery in common brewer's yeast of a new, infectious, misfolded protein -- or prion -- by University of Illinois at Chicago molecular biologists raises new questions about the roles played by these curious molecules, often associated with degenerative brain diseases like "mad cow" and its human counterpart, Creutzfeldt-Jakob.

Malaria immunity trigger found for multiple mosquito species

Researchers at the Johns Hopkins Bloomberg School of Public Health have for the first time identified a molecular pathway that triggers an immune response in multiple mosquito species capable of stopping the development of Plasmodium falciparum -the parasite that causes malaria in humans.
