Changes in 300 genes could contribute to the maternal behaviour of mice

A research team from the University of Valencia and the Jaume I University of Castellón shows an increase in the expression of 197 genes in mother mice, and a decrease of 99, when compared with virgin females in contact with offspring. These results.....»»

The recessive genes that make a carrot orange

A new study of the genetic blueprints of more than 600 types of carrot shows that three specific genes are required to give carrots an orange color. Surprisingly, these three required genes all need to be recessive, or turned off. The paper's finding.....»»

A better understanding of gene regulation in embryonic stem cells

During the first hours of an embryo's development, specialized molecules called pioneer transcription factors unravel parts of its DNA to activate the encoded genes. Which gene is activated and when has to follow a set schedule so that genes that are.....»»

Study clarifies how "junk DNA" influences gene expression

For decades, scientists have known that, despite its name, "junk DNA" in fact plays a critical role: While the coding genes provide blueprints for building proteins, which direct most of the body's functions, some of the noncoding sections of the gen.....»»

Researchers develop first method to study microRNA activity in single cells

MicroRNAs are small molecules that regulate gene activity by binding to and destroying RNAs produced by the genes. More than 60% of all human genes are estimated to be regulated by microRNAs; therefore, it is not surprising that these small molecules.....»»

Towards a better understanding of early human embryonic development

The onset of embryo-specific gene transcription, also known as embryonic genome activation (EGA), is a crucial step in the developmental journey of an organism. Although EGA has been studied to some extent in mice, human EGA remains largely unexplore.....»»

New origin story for key regulatory gene: PRC2 repressed jumping genes in ancestors of eukaryotes

The key protein complex PRC2 was discovered decades ago to silence genes, but new findings by Frederic Berger and his group at the Gregor Mendel Institute show that PRC2 represses transposons in a range of eukaryotes and only gradually evolved to sil.....»»
