Potential Treatment Option for Children With Ewing's Sarcoma

July 6, 2015 — A new therapeutic alternative for children who suffer from a malignant pediatric tumor bone and soft tissue called Ewing's sarcoma has been discovered by a research consortium. Ewing's ... read more

tRNAs Are Segmented Into Fragments in a Manner That Depends on Race, Gender and Population

July 6, 2015 — The study reports on a newly discovered category of tRNA fragments as well as shows that all tRNAs are rich sources of very diverse short molecules whose characteristics depend on a person's ... read more

Visualizing RNAi at Work

July 6, 2015 — Researchers have revealed the molecular mechanism of RNA interference (RNAi), the phenomenon by which the synthesis of a specific protein is inhibited, by real time observation of target RNA cleavage ... read more

July 6, 2015 — Researchers have identified modes of Sox9 action during cartilage formation by analyzing big data on Sox9 location, chromatin state, and gene expression over the whole mouse genome. This finding will ... read more

July 3, 2015 — The DNA molecule is chemically unstable giving rise to DNA lesions of different nature. That is why DNA damage detection, signaling and repair, collectively known as the DNA damage response, are ... read more

July 2, 2015 — By growing two types of stem cells in a '3-D culture' and measuring their ability to produce retinal cells, a team of researchers has found one cell type to be better at producing retinal ... read more

July 2, 2015 — A team using electron cryomicroscopy has for the first time revealed at the atomic level the structure of a protein required for viral replication in vesicular stomatitis virus, a virus that is a ... read more

Genetic Variation Determines Response to Anti-Diabetic Drug

July 2, 2015 — In the first study of its kind, researchers have shown how an anti-diabetic drug can have variable effects depending on small natural differences in DNA sequence between individuals. They aim to ... read more

July 2, 2015 — Cartilage does a lot more than determine the shapes of people's ears and noses. It also enables people to breathe and to form healthy bones -- two processes essential to life. A new study ... read more
