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.

Scientists identify novel mechanism that can reorganize cell's genetic architecture to promote senescence

Senescence, a phenomenon in which cells cease to divide and grow, can be caused by everything from natural DNA damage to treatment with chemotherapy. However, several mechanisms allow for cells to bypass senescence and grow out of control, eventually becoming cancerous.

Researchers transform bacteria into 'secret agents' for detecting disease

Another step forward has just been taken in the area of synthetic biology. Research teams from Inserm and CNRS (French National Centre for Scientific Research) Montpellier, in association with Montpellier Regional University Hospital and Stanford University, have transformed bacteria into "secret agents" that can give warning of a disease based solely on the presence of characteristic molecules in the urine or blood. To perform this feat, the researchers inserted the equivalent of a computer programme into the DNA of the bacterial cells.

KeyGenes platform could be useful for testing quality of stem cell transplants

A snapshot of gene activity is now all that's necessary to determine what organ or tissue type that a cluster of fetal stem cells will ultimately become. An algorithm developed by a team of Dutch scientists makes it possible to match what's happening inside of an immature stem cell to known human fetal cell gene expression, thus identifying what the stem cell has the potential to be.

Researchers uncover critical role for two proteins in chromatin structure

A team of researchers at the IRCM led by François Robert, PhD, uncovered a critical role for two proteins in chromatin structure. Their breakthrough, recently published in the scientific journal Molecular Cell, helps explain how DNA is organized in our cells. This discovery could lead to a better understanding of what causes certain types of cancer, such as lymphoma.

Differences in brain expression of RORA protein levels may lead to sex bias in autism

George Washington University researcher Valerie Hu, Ph.D., has found an important sex-dependent difference in the level of RORA protein in brain tissues of males and females. Specifically, females without autism have a slightly higher level of RORA in the frontal cortex of the brain than males without autism, while the levels of the protein are comparably lower in the brain of both males and females with autism.

Airway and systemic inflammation predict COPD exacerbation

Researchers have found a link between increased airway and systemic inflammation and frequent exacerbations in patients with chronic obstructive pulmonary disease.

NYU chemists find that microRNA can serve as 'decoder ring' for understanding biological functions

MicroRNA can serve as a "decoder ring" for understanding complex biological processes, a team of New York University chemists has found. Their study, which appears in Proceedings of the National Academy of Sciences, points to a new method for decrypting the biological functions of enzymes and identifying those that drive diseases.

Study explores how one genome could produce three different castes within bumblebees

Biologists from the University of Leicester have discovered that one of nature's most important pollinators - the buff-tailed bumblebee - either ascends to the status of queen or remains a lowly worker bee based on which genes are 'turned on' during its lifespan.

Johns Hopkins researchers identify new therapy to treat lung cancer

A multidisciplinary team led by Johns Hopkins researcher Venu Raman, Ph.D., with notable contributions from Guus Bol, Farhad Vesuna and Phuoc Tran of Johns Hopkins, has identified a new therapy for lung cancer, the most common cancer worldwide. The therapy has been in development for six years and involves a first-in-class molecule designed by the team.

Researchers reveal molecular steps that allow pancreatic cancer to spread to the liver

An international team led by Weill Cornell Medical College investigators has illuminated the precise molecular steps that enable pancreatic cancer to spread to the liver -- the event that makes the most common form of the disease lethal. By understanding this process, investigators say their discovery can lead to targeted treatments that delay metastasis, and could offer clinicians a new biomarker to test for the earliest signs of pancreatic cancer.

Researchers discover how and where chromosome fragile sites occur in human DNA

Using a novel method they developed to map chromosome breaks in a model organism, the budding yeast, Wenyi Feng, Ph.D., of Upstate Medical University and her colleagues have discovered new information as to how and where chromosome fragile sites can occur in human DNA. These sites are frequently observed in cancer cells and are responsible for causing genomic rearrangements.
