Massive microRNA scan uncovers leads to treating muscle degeneration
Researchers have discovered the first microRNAs - tiny bits of code that regulate gene activity - linked to each of 10 major degenerative muscular disorders, opening doors to new treatments and a better biological understanding of these debilitating, poorly understood, often untreatable diseases. view more (2007-10-18)
Molecules might identify high-risk acute-leukemia patients
New research suggests that certain small molecules used by cells to control the proteins they make might also help doctors identify adult acute-leukemia patients who are likely to respond poorly to therapy. view more (2008-01-16)
Brain tissue reveals possible genetic trigger for schizophrenia
A study led by scientists from the University of North Carolina at Chapel Hill may have identified a molecular mechanism involved in the development of schizophrenia. view more (2007-03-29)
Scientists dig deeper into the genetics of schizophrenia by evaluating microRNAs
Researchers at Columbia University Medical Center have illuminated a window into how abnormalities in microRNAs, a family of molecules that regulate expression of numerous genes, may contribute to the behavioral and neuronal deficits associated with schizophrenia and possibly other brain disorders. view more (2008-05-12)
Evolving complexity out of 'junk DNA'
The study, published today in Proceedings of the National Academy of Sciences, USA, claims to have solved this scientific riddle by analysing the genomics of primitive living fishes such as sharks and lampreys and their spineless relatives, such as the sea squirts. view more (2008-02-12)
Gladstone scientists identify role of tiny RNAs in controlling stem cell fate
Researchers at the Gladstone Institute of Cardiovascular Disease (GICD) and the University of California, San Francisco have identified for the first time how tiny genetic factors called microRNAs may influence the differentiation of pluripotent embryonic stem (ES) cells into cardiac muscle. view more (2008-03-06)
Small RNAs can play critical roles in male infertility/contraception
University of Nevada School of Medicine scientists in the Department of Physiology and Cell Biology have discovered insight into the reproductive workings of the male sex chromosome that may have significant implications for male infertility and contraception. view more (2009-04-10)
Master switches found for adult blood stem cells
Johns Hopkins Kimmel Cancer Center scientists have found a set of "master switches" that keep adult blood-forming stem cells in their primitive state. view more (2007-02-12)
MicroRNAs help zebrafish regenerate fins
Biologists have discovered a molecular circuit breaker that controls a zebrafish's remarkable ability to regrow missing fins, according to a new study from Duke University Medical Center. view more (2008-03-17)
Scaling the Wall of Deafness
Despite modern medicine, one in 1,000 American babies are born deaf. The numbers increase markedly with age, with more than 50% of seniors in the United States experiencing some form of hearing loss. view more (2009-04-15)
Two suppressor molecules affect 70 genes in leukemia
By restoring two small molecules that are often lost in chronic leukemia, researchers were able to block tumor growth in an animal model. view more (2008-04-25)
MicroRNAs circulating in blood show promise as biomarkers to detect pancreatic cancer
A blood test for small molecules abnormally expressed in pancreatic cancer may be a promising route to early detection of the disease. view more (2009-09-08)
MicroRNA helps prevent tumors
A microRNA directly regulates a gene implicated in human cancers, researchers from Whitehead Institute and Massachusetts Institute of Technology report in the February 22nd online issue of Science. view more (2007-02-23)
Regulatory molecule for tumor formation or suppression identified by Singapore, US researchers
One of the small regulatory molecules, named microRNA-125b, is a novel regulator of p53, an important protein that safeguards cells against cancers, Singapore and U.S. scientists report in the March 17, 2009 issue of the journal Genes & Development. view more (2009-03-18)
Researchers find snippet of RNA that helps make individuals remarkably alike
"No two people are alike." Yet when we consider the thousands of genes with frequent differences in genetic composition among different people, it is remarkable how much alike we are. view more (2009-05-06)
Molecules can block breast cancer's ability to spread
Researchers have identified a specific group of microRNA molecules that are responsible for controlling genes that cause breast cancer metastasis. view more (2008-01-10)
Gladstone scientists identify critical gene factor in heart development
Researchers at the Gladstone Institute of Cardiovascular Disease (GICD) announced they have identified a critical genetic factor in the control of many aspects of heart form and function. view more (2007-03-30)
Researchers find lack of key molecule leads to deafness
Researchers have identified tiny molecules that may lead to big breakthroughs in the treatment of hearing loss and deafness. view more (2009-04-17)
A small leak will sink a great ship
Flowers of higher plants are built in a similar pattern: their outermost whorl is composed of sepals, which protect the young bud, thereafter comes a whorl of often colorful petals attracting insect pollinators, followed by a whorl of stamens with pollen sacks and the innermost whorl holds carpels, which later give rise to the fruit and seeds. view more (2007-06-27)
UCSF team closer to creating safe embryonic-like stem cells
A team of UCSF researchers has for the first time used tiny molecules called microRNAs to help turn adult mouse cells back to their embryonic state. view more (2009-04-13)
