Effect on breast tumors of DNA alternations in 3 genes described

...at causes genes that promote normal cell growth to produce proteins that cause malignant behavior, or unregulated cell growth. Until now, data has been very limited regarding the mechanism and causes of hypermethylation, especially for hypermethylation in breast cancer. The purpose of the current study was ...

Scientists seek useful traits in wild cottons

...are photoperiodic," Gannaway said. "They will only produce fruit and seed during the short days of temperate ... laugh" The lint, or fiber, these cottons produce is also measured, analyzed and recorded. The lint is hand-, saw- and roller-ginned, and then charact...

Latent memory of cells comes to life

...NA splits into two single strands, which then each produce a new double-strand. Nucleosomes though are not duplicated like the DNA-strands. Rather, they are distributed between the two new DNA double strands and the empty spaces are filled by new nucleosomes. Cell division is therefore an opportunity for...

Hives ferment a yeasty brew, attract beetle pest

Newly identified mechanism for silencing genes points to possible anti-cancer strategies

...e the instructions used by the individual cells to produce the many different proteins that make up the body. Scientists are only beginning to appreciate, however, the extraordinary degree of control exercised over every step of the production process. Only about 10 percent of human genes, for example, are...

Danish researches solve virus puzzle

Deconstructing brain wiring, one neuron at a time

...conducted using slices of brain, it is possible to produce transgenic mice that will express specific genes in a targeted class of neurons, Callaway says. "All neurons of the type we select will then express the avian viral receptor and the rabies virus protein, allowing the modified rabies virus to infect t...

MIT's ocean model captures diversity of underwater forests

...le-celled green plants that dominate the ocean and produce half the oxygen we breathe on Earth. And it does so in a way that is consistent with the way real-world ecosystems evolve according to the principles of natural selection. Scientists use models such as this one to better understand the oceans' bi...

Bones in motion: Brown scientists to create new 3-D X-ray system

... a technique that uses X-rays to view objects, can produce moving images in two dimensions, but not 3-D. An orthopedic surgeon trying to figure out the best way to repair a torn knee ligament or an evolutionary biologist tracing the disappearance of digits in pigs would face a difficult task. To see the e...

Researchers develop marker that identifies energy-producing centers in nerve cells

... the neurons function like cellular powerhouses to produce those impulses through a metabolic process that combines oxygen with food calories. It is these nerve signals that cause muscles to move and thoughts to be processed. Dr. Chandrasekaran says the fluorescent marker system may make it possible to explo...

Tibetan antelope slowly recovering, WCS says

...hides largely ceased to exist. Tibetan antelope produce the finest wool in the world, known as shahtoosh, which translates to "king of wool." Beginning in the late 1980s, shahtoosh shawls became fashionable in Europe and the U.S., which fueled a black market and widespread poaching in this remote area. ...

Genetic fingerprints identify brain tumors' origins

...e," Gutmann says. Previous studies have failed to produce any solid leads on the genetic alterations that predispose children to PAs. "It should be recognized that the genetic alterations in this tumor may be very subtle," Gutmann notes. "When we looked at gene activity levels in the tumors as a function...

Super-fermenting fungus genome sequenced

...glucose and xylose, which can then be fermented to produce ethanol. Additional energy is required for the distillation process to achieve a fuel-grade product. Now, the power of genomics is being directed to optimize this age-old process. “The information embedded in the genome sequence of Pichia has he...

Scientists identify pancreatic cancer stem cells

...te that only 100 of these stem cells are needed to produce human pancreatic cancer in half of mice tested. They also found these cells are at least 100 times more tumorigenic than cancer cells that did not have one of three protein markers they believe to be associated with pancreatic cancer stem cells. T...

Noise echoes in cell communications

This randomness, however, isn't problematic, but a necessary function for survival. Until now, the role of randomness in sustaining li...
