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.

Researchers separate low and high-PSA prostate cancer cells

Prostate cancer cells that defy treatment and display heightened tumor-generating capacity can be identified by levels of prostate specific antigen (PSA) expressed in the tumor cells, a research team led by scientists at The University of Texas MD Anderson Cancer Center reports in the May 3 edition of Cell Stem Cell.

New light on many biological differences between individual breast cancers

New findings presented at Europe's leading breast cancer translational research conference this year shed new light on the many biological differences between individual breast cancers.

Potential breast cancer patients for new immune-targeting therapies

Breast cancer patients whose tumors express high levels of genes related to immune response are more likely to have their tumor completely eradicated by pre-operative chemotherapy compared to patients with low expression of these genes, Belgian researchers report at the 4th IMPAKT Breast Cancer Conference in Brussels, Belgium.

Researchers identify new functions of cohesin SA1 that are relevant for cancer and CdLS

Cohesin is a ring-shaped protein complex involved in the spatial organization of the genome and in mitotic chromosome structure. Vertebrate somatic cells have two versions of cohesin that contain either SA1 or SA2, but their functional specificity has been largely ignored. Researchers of the Spanish National Cancer Research Centre (CNIO) under the direction of Ana Losada have identified new functions of cohesin SA1 that are relevant for two human diseases, cancer and Cornelia de Lange Syndrome.

Potential ways for doctors to improve hormone receptor-positive breast cancer treatment

American and Spanish researchers have found potential ways for doctors to improve the treatment of hormone receptor-positive breast cancer even if they lack access to costly multi-gene tests, as they report at the 4th IMPAKT Breast Cancer Conference.

Affymetrix total revenue decreases to $65.2 million

Affymetrix, Inc., today reported its operating results for the first quarter of 2012. Total revenue for the quarter was $65.2 million, as compared to total revenue of $73.7 million for the same period of 2011.

Study: Breast cancer in young women is enriched with aggressive basal-like tumors

Breast cancer in young women is a biologically unique disease that requires customized management strategies, researchers report at the 4th IMPAKT Breast Cancer Conference, in Brussels, Belgium.

Researchers identify switches that can turn on or off genes associated with colorectal cancer

Two researchers at the Geisel School of Medicine at Dartmouth have helped to identify switches that can turn on or off genes associated with colorectal cancer. The finding offers clues about the development of colorectal cancer and could-potentially-provide targets for new therapies.

Scientists discover new type of dynamic change in human stem cells

A team led by scientists at The Scripps Research Institute and the University of California (UC) San Diego has discovered a new type of dynamic change in human stem cells.

Hypoxia may be a primary cause of uncontrollable tumor growth in cancers

Low oxygen levels in cells may be a primary cause of uncontrollable tumor growth in some cancers, according to a new University of Georgia study. The authors' findings run counter to widely accepted beliefs that genetic mutations are responsible for cancer growth.

Combination of two mTOR inhibitors stops growth of hepatocellular carcinoma

The combination of two inhibitors of protein mTOR stops the growth of primary liver cancer and destroys tumour cells, according to a study by researchers of the Group of Metabolism and Cancer at Bellvitge Biomedical Research Institute.

Novel stem cell transplantation holds promise for HIV prevention

UC Davis Health System researchers are a step closer to launching human clinical trials involving the use of an innovative stem cell therapy to fight the virus that causes AIDS.

JAD honors Norwegian scientist with 2012 Alzheimer Award

Anders L-nneborg, PhD, has been chosen as the recipient of the 2012 Alzheimer Award presented by the Journal of Alzheimer's Disease in recognition of his outstanding work on the detection of early Alzheimer's disease.

Researchers discover how protein ARTD1's DNA recruitment is regulated during inflammation

During inflammation, controlled gene expression is necessary in order to allow the organism to mount an effective defense response. For this process, the protein ARTD1 is removed from the DNA.

CHR-3996 pill shows promise against advanced cancers

Scientists have shown that a brand new type of cancer pill that exploits the emerging field of epigenetics is safe for human use, according to a Phase I trial reported today in Clinical Cancer Research.

Mirror-microRNAs control multiple aspects of brain function

Our genes control many aspects of who we are - from the colour of our hair to our vulnerability to certain diseases - but how are the genes, and consequently the proteins they make themselves controlled? Researchers have discovered a new group of molecules which control some of the fundamental processes behind memory function and may hold the key to developing new therapies for treating neurodegenerative diseases.

UAB researcher wins HudsonAlpha Prize for work on sickle cell and related blood disorders

Tim Townes, Ph.D., University of Alabama at Birmingham, was awarded the HudsonAlpha Prize for his work on sickle cell and related blood disorders. The $20,000 monetary award acknowledges exceptional talent, dedication and discovery by Alabama's best and brightest researchers.

Researchers discover small molecules that kill HPV-infected cancer cells

Researchers at The Wistar Institute announce the discovery of small molecules that kill cancer cells caused by infection with human papillomavirus (HPV). Their results, in both cell and mouse models, demonstrate that the small molecule inhibitors protect a tumor-suppressing protein targeted by viral proteins, thus killing the infected tumor cells.

Researchers identify new components of genetic pathway that controls neural stem cells

Can one feel too attached? Does one need to let go to mature? Neural stem cells have this problem, too. As immature cells, neural stem cells must stick together in a protected environment called a niche in order to divide so they can make all of the cells that populate the nervous system. But when it's time to mature, or differentiate, the neural stem cells must stop dividing, detach from their neighbors and migrate to where they are needed to form the circuits necessary for humans to think, feel and interact with the world.

Scientists identify linchpin of fat metabolism

Humans are built to hunger for fat, packing it on during times of feast and burning it during periods of famine. But when deluged by foods rich in fat and sugar, the modern waistline often far exceeds the need to store energy for lean times, and the result has been an epidemic of diabetes, heart disease and other obesity-related problems.
