A twist of fate -- Reprogrammed fibroblasts resemble embryonic stem cells
Stem cell biology takes another exciting leap forward as scientists report that normal tissue cells can be reprogrammed to exhibit many of the properties that are characteristic of embryonic stem cells, including the ability to give rise to multiple cell types and contribute to the germline. view more (2007-06-07)
Cold Spring Harbor Scientists Reveal A Protein's Role in Enabling AIDS Virus to Reproduce
A team of scientists at Cold Spring Harbor Laboratory (CSHL) has discovered new details about how a simian strain of the AIDS virus replicates. view more (2008-05-27)
Genes linked to daily flux in drug toxicity
New findings in the July, 2006, Cell Metabolism, published by Cell Press, may help to explain daily fluctuations in the ability to detoxify chemical substances, including chemotherapy drugs and sedatives. view more (2006-07-06)
Making sense of antisense microRNAs
Three independent papers in the January 1st issue of G&D report on the discovery of a bidirectionally transcribed microRNA (miRNA) locus in Drosophila. view more (2008-01-02)
Researchers identify cell pathway in colon cancer
For the one in 18 men and women who will be diagnosed with cancer of the colon and rectum during their lifetime and over 150,000 people diagnosed on a yearly basis, today's genetic research news offers some optimism. view more (2007-02-21)

Scientists have provided new insight into how a gene is related to schizophrenia. view more (2007-08-10)
Clue found to Epstein-Barr virus' ability to form and sustain tumors
Researchers at the University of Wisconsin School of Medicine and Public Health (SMPH) have found a viral target that opens the door for the development of drugs to destroy tumors caused by Epstein-Barr virus (EBV). view more (2006-09-06)
Key root-development pathway mapped using advanced genomic technique
Biologists have vastly expanded understanding of the biological machinery controlling the intricate process by which plant roots burgeon from single cells into complex tissues. view more (2006-05-05)
Scientists unlock solid tumor treatment genetic secrets
A biochemical mechanism that cells use to cope with hypoxia (lack of oxygen) actually cooperates with a less well-known mechanism that helps increase the expression of those hypoxia-sensitive genes. view more (2005-12-02)
MIT, BU engineer cellular circuits that count events
MIT and Boston University engineers have designed cells that can count and "remember" cellular events, using simple circuits in which a series of genes are activated in a specific order. view more (2009-05-29)
Genes that both extend life and protect against cancer identified
A person is 100 times more likely to get cancer at age 65 than at age 35. But new research reported today in the journal "Nature Genetics" identifies naturally occurring processes that allow many genes to both slow aging and protect against cancer in the much-studied C. elegans roundworm. view more (2007-10-15)
RNA emerges from DNA's shadow
RNA, the transporter of genetic information within the cell, has emerged from the shadow of DNA to become one of the hottest research areas of molecular biology, with implications for many diseases as well as understanding of evolution. view more (2008-07-11)
Getting wired: how the brain does it
In a new study, researchers at the Montreal Neurological Institute and Hospital (The Neuro), McGill University have found an important mechanism involved in setting up the vast communications network of connections in the brain. view more (2009-08-27)
Fox Chase Researchers Uncover One Force Behind the MYC Oncogene in Many Cancers
DLX5, a gene crucial for embryonic development, promotes cancer by activating the expression of the known oncogene, MYC, according to researchers from Fox Chase Cancer Center. view more (2009-07-29)
Blood sugar's manufacture limited by building blocks' supply
Researchers have discovered a factor that controls blood sugar's manufacture in a novel way: by limiting the supply of its building blocks. The findings are reported in the April issue of the journal Cell Metabolism, published by Cell Press. view more (2007-04-04)
Researchers identify gene causing rare form of cleft palate
The identification of a gene that causes a rare form of the congenital defect, cleft palate, may offer an important insight into human development and the mechanisms involved in the condition. Researchers led by Dr Philip Stanier from Imperial College have found that the sex-linked form of cleft palate (CPX) and an associated form of the disorder... view more... (2001-09-14)
Mayo Clinic Researchers Find Experimental Therapy Turns on Tumor Suppressor Gene in Cancer Cells
Researchers at Mayo Clinic have found that the experimental drug they are testing to treat a deadly form of thyroid cancer turns on a powerful tumor suppressor capable of halting cell growth. Few other cancer drugs have this property, they say. view more (2009-01-20)
The development of stem cells -- not only which and where but also WHEN
Yet another stride has been taken on the road to knowledge about the development of the nervous system. For the first time factors have been uncovered that decide when a cell is to develop into another cell. During the last ten years much progress has been made in finding out what determines how various types of nerve cells develop from a stem... view more... (2003-03-20)
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)
