Their goal is to alter those neurons genetically by introducing mutations know to cause Alzheimer's disease in people, to then test for transport defects, and then study whether those defects produce pathology similar to that seen in Alzheimer's. One of the questions they ...

Plants, animals share molecular growth mechanisms

... engineer plant cells to grow in different ways or alter how cells respond to external stimuli so they can defend themselves against insect or fungal attacks," Szymanski said. A protein complex known as Actin Related Protein 2/3 (ARP2/3) is a cellular machine that controls formation of actin filaments, wh...

Study of genomic DNA leads to new advances in cancer diagnostics

...ite in the body to another. The researchers could alter the Alu I sensitivity of a cell's chromatin by exposing the cell to a single extracellular matrix molecule or by disrupting any of three cytoskeletal systems, which link the outside of the cell to the genome. Using this information, Dr. Maniotis's gr...

FDA Approves New Drug to Treat Type I and Type II Diabetes

...Symlin with insulin in the same syringe, which can alter the activity of the insulin, is addressed in the Medication Guide and in physician labeling. Finally, the potential for off-label use in patients where the benefit/risk profile has not been characterized or demonstrated is also a concern and will be ...

VCU Researchers Identify Networks Of Genes Responding To Alcohol In The Brain

...suggested that interfering with Bdnf signaling can alter alcohol consumption. If researchers can identify drugs that may inhibit or activate the function of one of the genes identified in these studies, they may be able to generate new treatments for alcoholism or addiction, Miles said. "The genes identi...

Researchers discover molecular mechanism that desensitizes us to cold

... PIP2. Cold or menthol stimulate this receptor and alter the electrical properties of the membrane, a process that leads to the sensation of cold. When the receptor is stimulated, calcium enters the cell and stimulates the breakdown of PIP2. When PIP2 is broken down, the receptor becomes inactive, thus end...

Researchers discover chemical compounds that affect plant growth

...vel compounds that affect the ability of plants to alter their direction of growth in response to gravity, a phenomenon known as gravitropism. The researchers screened a library of 10,000 small molecules, the practice is known as chemical genomics, to identify those that could positively or negatively aff...

Scientists discover how plants disarm the toxic effects of excessive sunlight

... nothing has previously been known about how cells alter gene expression to respond to singlet oxygen. We may now be able to design pharmaceuticals that target this response, and ultimately may help us mitigate disease." Donohue's co-authors on his study were a microbiology graduate student, Jennifer Anth...

Researchers rein in regulatory RNAs

...ted loci. Antisense transcripts have been shown to alter the methylation status of the overlapping partner gene. SATs might also trigger posttranscriptional gene regulation via RNA interference (RNAi) by virtue of their ability to form double-stranded RNA (dsRNA) molecules. A large proportion of these ant...

Revolutionary nanotechnology illuminates brain cells at work

...view changes in brain chemical levels. The sensors alter their 3-dimensional form upon binding with the chemical, which is then visible via a process known as fluorescence resonance energy transfer, or FRET. In a new study, the nanosensors were introduced into nerve cells to measure the release of the neur...

Cerebral navigation: How do nerve fibers know what direction to grow in?

...rs, ephexin1 is chemically modified, causing it to alter the cell's cytoskeleton, or internal scaffolding. This alteration makes the growth cone collapse, steering the axon in a new direction or halting its growth. In chicken motor neurons whose ephexin1 was inactivated, the axons grew into the hind limb p...
