Researchers at Karolinska Institutet have mapped how small RNA molecules, such as the recently Nobel Prize-awarded microRNAs, control cell development in the human embryo during the first days after fertilization. The findings, ...
A critical transition in early human development is regulated not by our own genes, but by DNA elements called transposons that can move around the genome, Sinai Health researchers have found.
Studying the secrets of how the common red milkweed beetle can safely feed on a toxic plant helps illuminate the ecological, evolutionary and economic impact of insect-plant interactions from a genomic perspective.
It's one of the basic tenets of biology: We get our DNA from our mom and our dad. But one notable exception has perplexed scientists for decades: Most animals, including humans, inherit the DNA inside their mitochondria—the ...
A group of essential signaling molecules known as the Wnt pathway emerged early in the evolution of multicellular life. Scientists have been studying Wnt actions for four decades to comprehend its complex roles in development ...
Christian de Caestecker, a Ph.D. student in the lab of Ian Macara, Louise B. McGavock Professor and chair of the Department of Cell and Developmental Biology, has proposed and validated a mechanism that addresses a decades-old ...
Sea robins are ocean fish particularly suited to their bottom-dwelling lifestyle. Six leg-like appendages make them so adept at scurrying, digging, and finding prey that other fish tend to hang out with them and pilfer their ...
Researchers at the Max Planck Institute for Molecular Genetics in Berlin and the Institute of Molecular Biotechnology (IMBA) of the Austrian Academy of Sciences in Vienna have discovered a potential "pause button" in the ...
Endocytosis and recycling control the uptake and retrieval of various materials in eukaryotic cells. Mammalian cells have developed several recycling routes, including the relatively extensively studied "fast" and "slow" ...
Researchers have identified key cellular control sites that regulate gene expression and prevent the activation of "cryptic" genomic regions, including ancient viral sequences.
