Equality of the sexes? Not always when it comes to biology
When it comes to immunity, men may not have been dealt an equal hand. The latest study by Dr. Maya Saleh, of the Research Institute of the McGill University Health Centre and McGill University, shows that women have a more powerful immune system than men. view more (2009-05-12)
Gene “shaving” could help doctors predict the efficacy of cancer treatments
A new statistical method that identifies similar groups of genes from large tissue samples could be used by health care professionals to predict the effectiveness of treating patients suffering from a variety of disorders including cancer, according to a research article published in Genome Biology today. The statistical method, named gene... view more... (2000-08-02)
Study finds value in 'junk' DNA
For about 15 years, scientists have known that certain "junk" DNA -- repetitive DNA segments previously thought to have no function -- could evolve into exons, which are the building blocks for protein-coding genes in higher organisms like animals and plants. view more (2008-10-17)
A tumor suppressor that promotes cancer cell growth?
Researchers have shown that the tumor suppressor gene H-REV107-1 may actually stimulate tumor progression in some non-small cell lung carcinomas. view more (2006-10-09)
New biomarkers for lupus found
A Wake Forest University School of Medicine team believes it has found biomarkers for lupus that also may play a role in causing the disease. view more (2006-11-13)
A potential targets for the prevention or treatment of esophageal carcinoma
Expression of Livin in fresh esophageal cancer tissues was detected by immunohistochemistry (IHC), Western blotting and reverse transcriptase-polymerase chain reaction (RT-PCR), VEGF by Its correlation Western blotting and RT-PCR. view more (2008-10-29)
Ali Shilatifard and Colleagues Aim to Clarify the Definition of "Epigenetics"
Ali Shilatifard, Ph.D., Investigator, has joined with a team of colleagues to propose an operational definition of "Epigenetics" - a rapidly growing research field that investigates heritable alterations in gene expression caused by mechanisms other than changes in DNA sequence. view more (2009-04-02)
APL regulates vascular tissue identity in Arabidopsis
Plants have a conductive tissue, phloem, for transporting sugars and hormones to non-green parts after photosynthesis. Phloem has two basic cell types, enucleate sieve elements (SE) and companion cells (CC). Scientists from the University of Helsinki have developmentally analyzed the process of phloem development in Arabidopsis plant and... view more... (2003-11-13)
International team reveals first prognosticator of survival in aggressive cancer
The tumor suppressor gene pRb2/p130 may provide the first independent prognostic biomarker in cases of soft tissue sarcoma (STS). view more (2008-09-04)
Gene-regulating enzyme is also a target for anti-depressive drugs
In 2005, professor Ramin Shiekhattar, Ph.D., at The Wistar Institute and his colleagues reported details about an enzyme involved in appropriately repressing sets of neuronal genes in non-neuronal cells. view more (2006-06-26)
Social interactions can alter gene expression in the brain, and vice versa
Our DNA determines a lot about who we are and how we play with others, but recent studies of social animals (birds and bees, among others) show that the interaction between genes and behavior is more of a two-way street than most of us realize. view more (2008-11-07)
MIT reels in RNA surprise with microbial ocean catch
An ingenious new method of obtaining marine microbe samples while preserving the microbes' natural gene expression has yielded an unexpected boon: the presence of many varieties of small RNAs - snippets of RNA that act as switches to regulate gene expression in these single-celled creatures. view more (2009-05-14)
New method for gene expression experiments akin to watercolor painting in water
Like oil and water, two water-based liquids can mingle without mixing in a new University of Michigan technology developed for biological experiments. view more (2009-08-19)
Gene signature helps predict breast cancer prognosis
Vanderbilt-Ingram Cancer Center researchers have uncovered a gene signature that may help predict clinical outcomes in certain types of breast cancer. view more (2009-05-20)
Researchers identify gene as protector of DNA, enemy of tumors
A single gene plays a pivotal role launching two DNA damage detection and repair pathways in the human genome, suggesting that it functions as a previously unidentified tumor suppressor gene. view more (2006-08-07)
Nanotech particles affect brain development in mice
Maternal exposure to nanoparticles of titanium dioxide (TiO2) affects the expression of genes related to the central nervous system in developing mice. view more (2009-07-29)
First gene associated with myeloproliferative diseases
Myelodysplastic / myeloproliferative diseases (MDS/MPD) are blood stem cell disorders characterized by ineffective formation and development of blood cells in the bone marrow, resulting in abnormal development of bone marrow precursor cells and a reduction in the number of blood cells. view more (2005-08-26)
Cars and power
Cars promise autonomy as well as mobility for the 70 per cent of households in the UK which have access to one. This is the conclusion of psychologist Dr Steve Stradling from Napier University Transport Research Institute who presented his findings today, Friday 24 November, at The British Psychological Society Scottish Branch annual conference... view more...

New research reveals unexpected post-mating gene expression in model lab insect
That cloud of tiny flies hovering around spoiled fruit isn't just a nuisance. In fact, what science calls Drosophila melanogaster is more and more the key to intricate genetic studies that shed light on numerous biological processes, especially reproduction. view more (2006-06-28)
Microarray technology could help predict patient response to adjuvant therapy for breast cancer
Microarray technology could be used to tailor therapy according to the individual, and prevent breast cancer patients from having to undergo painful unsuccessful therapies. view more (2005-10-03)
