Medicine & Health news

The hidden complexity underlying a common cause of autism

Genes located in a large chromosomal aberration associated with autism interact with each other to modulate the variable symptoms of the disease, according to new research. A collaborative team led by Penn State researchers tested the role of these genes individually and in tandem by reducing the amount of the genes expressed in a fruit fly model. The research, which appears June 29, 2018 in the journal Nature Communications, demonstrates the utility of the fly as an experimental model for understanding the complex causation of human neurodevelopmental disorders and identifies potential targets for therapeutic treatment.

Mapping the brain with data science

Patients with dementia and other neural diseases show physical symptoms such as stumbling and confusion, but identifying the problem isn't as simple as taking an X-ray. A group of researchers at Purdue University are designing data-driven tools that will help clinicians better understand the progression of neurodegenerative diseases by identifying and tracking changes in the brain.

Restricting a key cellular nutrient could slow tumor growth

Remove tumor cells from a living organism and place them in a dish, and they will multiply even faster than before. The mystery of why this is has long stumped cancer researchers, though many have simply focused on the mutations and chains of molecular reactions that could prompt such a disparity. Now, a group of MIT researchers suggests that the growth limitations in live organisms may stem from a different source: the cell's environment. More specifically, they found that the amino acid aspartate serves as a key nutrient needed for the "proliferation" or rapid duplication of cancer cells when oxygen is not freely available.

Neural implants modulate microstructures in the brain with pinpoint accuracy

The diversity of structures and functions of the brain is becoming increasingly realized in research today. Key structures exist in the brain that regulate emotion, anxiety, happiness, memory, and mobility. These structures can come in a huge variety of shapes and sizes and can all be physically near one another. Dysfunction of these structures and circuits linking them are common causes of many neurologic and neuropsychiatric diseases. For example, the substantia nigra is only a few millimeters in size yet is crucial for movement and coordination. Destruction of substantia nigra neurons is what causes motor symptoms in Parkinson's disease.
