Brain repair after injury and Alzheimer's disease
Scientists at Penn State University have developed an innovative technology to regenerate functional neurons after brain injury. The technology may be developed into a new therapeutic treatment for traumatic brain and spinal cord injuries, stroke, Alzheimer's disease, Parkinson's disease, and other neurological disorders.

Protein links liver cancer with obesity, alcoholism, and hepatitis
A new study identifies an unexpected molecular link between liver cancer, cellular stress, and risk factors for developing this cancer -- obesity, alcoholism, and viral hepatitis. The study by University of Iowa researchers shows that a protein called CHOP, which had previously been thought to generally protect against cancer, actually promotes liver cancer in mice and may do the same in humans. The findings are published Dec. 19 in the journal PLOS Genetics.

Gladstone scientists discover how immune cells die during HIV infection; identify potential drug to block AIDS
Research led by scientists at the Gladstone Institutes has identified the chain of molecular events that drives the death of the immune system's CD4 T cells as an HIV infection leads to AIDS. Further, they have identified an existing anti-inflammatory drug that blocks the death of these cells -- and now are planning a Phase 2 clinical trial to determine if it can prevent HIV-infected people from developing AIDS.

Stowers researchers announce first genetic model of a human jaw fusion defect known as syngnathia
The face you critiqued in the mirror this morning was sculpted before you were born by a transient population of cells called neural crest cells. Those cells spring from neural tissue of the brain and embryonic spinal cord and travel throughout the body, where they morph into highly specialized bone structures, cartilage, connective tissue, and nerve cells.

A new -- and reversible -- cause of aging
Researchers have discovered a cause of aging in mammals involving a series of molecular events that disables communication between the nucleus and mitochondria. By administering a molecule naturally produced by the human body, the communication network was restored in older mice. Subsequent tissue samples showed biological hallmarks comparable to much younger animals.

Cocaine, meth response differ between 2 substrains of 'Black 6' laboratory mouse
Researchers including Jackson Laboratory Professor Gary Churchill, Ph.D., have found a single nucleotide polymorphism difference in cocaine and methamphetamine response between two substrains of the C57BL/6 or "Black 6" inbred laboratory mouse, pointing to Cyfip2 as a regulator of cocaine response with a possible role in addiction.

Gene transfer gone wild reveals driving force behind mitochondrial sex
Pioneering research led by Indiana University has identified genes from a number of plant species, including the entire mitochondrial genomes from three green algae and one moss, in the mitochondrial genome of Amborella trichopoda. The South Pacific shrub is considered to be the sole survivor -- the "last man standing" -- of one of the two oldest lineages of flowering plants, while the other lineage comprises the other 300,000 species of flowering plants.

Stem cells offer clues to reversing receding hairlines
Regenerative medicine may offer ways to banish baldness that don't involve toupees. The lab of USC scientist Krzysztof Kobielak, M.D., Ph.D., has published a trio of papers in the journals Stem Cells and The Proceedings of the National Academy of Sciences that describe some of the factors that determine when hair grows, when it stops growing and when it falls out.

Fatigue, a common side effect of breast cancer treatment, evaluated in novel patient study
Although the prevalence and impact of cancer-related fatigue has been well established, very little is known about its predictors, mechanisms for development, and persistence post-treatment. A new research study at the Cedars-Sinai Samuel Oschin Comprehensive Cancer Institute, in partnership with UCLA, is aimed at identifying breast cancer patients most susceptible to post-treatment fatigue by measuring biological, behavioral and social risk factors.

Role for sugar uptake in breast cancer revealed
Berkeley Lab researchers have shown that aerobic glycolysis -- glucose metabolism in the presence of oxygen -- is not the consequence of the cancerous activity of malignant cells, as has been widely believed, but is itself a cancerous event.

Neanderthal genome shows early human interbreeding, inbreeding
A team that includes UC Berkeley population geneticists has produced the first high-quality genome of a Neanderthal, allowing comparison with the genomes of modern humans and Denisovans. The analysis shows a long history of interbreeding among these early humans and a fourth, previously unknown group. The Neanderthal, from Denisova cave, also shows evidence of inbreeding. About 87 genes in modern humans were found to be significantly different from related genes in Neanderthals and Denisovans.

Markers of inflammation in the blood linked to aggressive behaviors
People with intermittent explosive disorder -- a psychiatric illness characterized by impulsivity, hostility and recurrent aggressive outbursts -- have elevated levels of two markers of systemic inflammation in their blood. The study documents a direct relationship between inflammatory markers and impulsive aggression that is not seen in people in good mental health or with other psychiatric disorders.

Brain area attacked by Alzheimer's links learning and rewards
One of the first areas of the brain to be attacked by Alzheimer's disease, the posterior cingulate cortex, or PCC, has been found to step in during a cognitive challenge to improve the brain's performance. This small study in monkeys establishes a role for the PCC in learning and its connection to the brain's reward system.

Newly identified immune receptor may activate B cells in autoimmunity

No link between HIV-prevention pill Truvada and increased sexual risk behavior
In 2012 the HIV antiretroviral drug Truvada became the first and only medication approved by the FDA for HIV prevention. Led by Gladstone Institutes' Investigator Robert Grant, M.D., M.P.H., this research was hailed as an important step towards reducing the worldwide HIV/AIDS epidemic. Now, a new study provides further proof that regular Truvada use can reduce one's risk for contracting HIV -- without increasing sexual risk behavior.

Silencing synapses
Imagine kicking a cocaine addiction by simply popping a pill that alters the way your brain processes chemical addiction. New research from the University of Pittsburgh suggests that a method of biologically manipulating certain neurocircuits could lead to a pharmacological approach that would weaken post-withdrawal cocaine cravings. The findings have been published in Nature Neuroscience.
