Two papers in the May 1 issue of Genes & Development reveal unexpectedly widespread genomic binding by the Myc protein – prompting scientists to consider that this highly studied human oncogene may still have a few secrets to reveal.
Independent research groups led by Drs. Robert Eisenman (Fred Hutchinson Cancer Center) and Bruno Amati (European Institute of Oncology) report on the first genome-wide analyses of in vivo Myc targets in the Drosophila and human genomes, respectively. As the myc gene is mutated in approximately one-third of all human cancers, the identification of the full range of genes that interact with Myc under normal conditions will be important to understanding how abnormal myc expression can lead to cancer.
The myc gene encodes a transcription factor (Myc) that, together with a partner protein (Max), binds to specific DNA sequences to regulate gene expression. myc is classified as an oncogene because genetic mutations that result in over-expression of Myc protein promote unregulated cell proliferation and cancer. While Myc has an established role in directing cell growth, proliferation, differentiation, and death, the precise molecular pathways of Myc action are still largely unknown.

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
