New Gene Variants Found to Raise Risk of Neuroblastoma and Influence Tumor Progression

Researchers have discovered two gene variants that raise the risk of the pediatric cancer neuroblastoma. This is the first study to link known cancer-related genes HACE1 and LIN28B to neuroblastoma. The study broadens understanding of how gene changes may make a child susceptible to this early childhood cancer, as well as causing a tumor to progress.... Read More...

Astrocytes Control the Generation of New Neurons from Neural Stem Cells

Neuroscience researchers show how astrocytes control the generation of new neurons in the brain. “In the brain, astrocytes control how many new neurons are formed from neural stem cells and survive to integrate into the existing neuronal networks. Astrocytes do this by secreting specific molecules but also by much less understood direct cell-cell interactions with stem cells”, says Prof. Milos Pekny.... Read More...

Brain’s Stem Cells Eavesdrop to Find Out When to Act

Working with mice, Johns Hopkins researchers say they have figured out how stem cells found in a part of the brain responsible for learning, memory and mood regulation decide to remain dormant or create new brain cells. Apparently, the stem cells “listen in” on the chemical communication among nearby neurons to get an idea about what is stressing the system and when they need to act.... Read More...

Researchers Find Genetic Cause for Body Tremors

Scientists knew that mutations in the FUS gene (Fused in Sarcoma) cause amyotrophic lateral sclerosis (ALS), a disease of the nerve cells in the brain and spinal cord that control voluntary muscle movement. The researchers were successful in identifying mutations in this gene that cause Essential Tremor, and proved that the disease mechanisms for ET and ALS FUS mutations are different.... Read More...

Study Suggests New Treatment Target for Deadly Brain Tumors

“We identified a subset of brain tumor cells that are slower growing or remain at rest, and appear to be the source of cancer recurrence after standard therapy in which the drug temozolomide is given to stop the tumor’s growth,” said Dr. Luis Parada. “Current therapy targets fast-growing tumor cells but not those responsible for new tumors. To the best of our knowledge, this is the first identification of a cancer stem-like cell in a spontaneously forming tumor inside a mammal.”... Read More...

Protein Involved in DNA Replication, Centrosome Regulation Linked to Dwarfism, Small Brain Size

Research just published by scientists at Cold Spring Harbor Laboratory (CSHL) links gene mutations found in some patients with Meier-Gorlin syndrome (MGS) with specific cellular dysfunctions that are thought to give rise to a particularly extreme version of dwarfism, small brain size, and other manifestations of abnormal growth which generally characterize that rare condition....
