Epigenetics: DNA Isn’t Everything
April 12, 2009 Research into epigenetics has shown that environmental factors affect characteristics of organisms. These changes are sometimes passed on to the offspring. Does this in any way oppose Darwin's theory ... > full story -
Definition Of 'Epigenetics' Clarified
April 1, 2009 Scientists are working to develop an operational definition of "epigenetics" -- a rapidly growing research field that investigates heritable alterations in gene expression caused by mechanisms other ... > full story -
Cancer Mutations In The Heart Of Gene Regulation
March 29, 2009 Researchers have identified a new cancer gene -- one that is common to many cancers and affects the most basic regulation of our genes. The new example -- a gene on the X chromosome called UTX -- is ... > full story -
Therapeutic Cloning Gets A Boost With New Research Findings
March 25, 2009 New research offers the first direct demonstration that cloning by somatic cell nuclear transfer does not lead to an increase in the frequency of point ... > full story -
Pollution-Related Asthma May Start In The Womb
February 14, 2009 Children born in areas with increased traffic-related pollution may be at greater risk of developing asthma due to genetic changes acquired in the womb, according to new ... > full story -
Roles Of DNA Packaging Protein Revealed
February 12, 2009 Scientists have found that a class of chromatin proteins is crucial for maintaining the structure and function of chromosomes and the normal development of eukaryotic ... > full story -
New Genes Involved In Acute Lymphoblastic Leukemia Play Fundamental Role In Prognosis Of The Disease
February 6, 2009 The inactivity or “silence” of certain genes plays a fundamental role in the prognosis of acute lymphoblastic leukemia (ALL) as well as in response to treatment, according to a new ... > full story -
How 'Companion' Cells To Sperm Protect Them From Genetic Damage
February 5, 2009 In plant pollen grains, sperm cells, which carry the genetic material to be passed on to progeny, are cocooned within larger "companion" cells that provide sperm with energy and nourishment. A team ... > full story -
Possible Drug Target For Obesity Treatment A 'No-Brainer'
February 4, 2009 Scientists have discovered a gene that when mutated causes obesity by dampening the body's ability to burn energy while leaving appetite ... > full story -
Rethinking The Genetic Theory Of Inheritance: Heritability May Not Be Limited To DNA
January 18, 2009 In the first study of its kind, scientists have detected evidence that DNA may not be the only carrier of heritable information; a secondary molecular mechanism called epigenetics may also account ... > full story
