One night of sleep loss negatively impacts fat, muscle tissue

Losing just one night of sleep can have a negative impact on human metabolism at the tissue level, according to a study published last week. The findings may explain how long-term shift work and chronic sleep loss can impair metabolism and adversely affect human body composition. Previous studies have shown that the risk […]

MU researchers create specialized delivery methods that could help treat cancer, other disorders

More than 100 years ago, German Nobel laureate Paul Ehrlich popularized the “magic bullet” concept — a method that clinicians might one day use to target invading microbes without harming other parts of the body. Although chemotherapies have been highly useful as targeted treatments for cancer, unwanted side effects still […]

Anti-cancer drug offers potential alternative to transplant for patients with liver failure, study finds

Acute Liver Failure occurs when a healthy liver is so seriously damaged it can no longer regrow and recover, leaving patients in urgent need of transplant. The liver helps support almost every other organ, by removing toxins, as well as making and storing the proteins and energy sources the body […]

Tissue architecture affects chromosome segregation

All growth and reproduction relies on a cell’s ability to replicate its chromosomes and produce accurate copies of itself. Every step of this process takes place within that cell. Based on this observation, scientists have studied the replication and segregation of chromosomes as a phenomenon exclusively internal to the cell. They […]

New Promise from Old Medicine

Investigators have discovered that arsenic in combination with an existing leukemia drug work together to target a master cancer regulator. The team, led by researchers at Harvard Medical School and the Cancer Center at Beth Israel Deaconess Medical Center, is hopeful that the discovery could lead to new treatment strategies […]

Cellular Escape Artists

More than two-thirds of women with ovarian cancer have high-grade serous carcinoma (HGSC). Up to 90 percent of HGSCs are not detected until they are beyond the ovaries or fallopian tubes, at which point it may not be possible to fully remove the tumor. Many of these cancers are now […]

Technology allowing different concentrations of drugs and chemicals on various parts of same tissue shows promise

A new technology developed by Purdue University researchers allows different concentrations of a drug or a chemical to be targeted at different areas of the same cancerous tissue in the laboratory. The discovery may help the more than 1.7 million people the National Cancer Institute predicts will be diagnosed with […]

Potent bacteria

A special strain of soil bacteria has the paradoxical ability to produce highly toxic compounds to protect itself from other organisms without harming itself. A collaboration that includes scientists from the Department of Energy’s (DOE) Argonne National Laboratory has discovered that the bacteria performs this feat by confining the toxic […]

Epigenetic patterns determine if honeybee larvae become queens or workers

Queen and worker honeybees are almost genetically identical but are fed a different diet as larvae. The researchers have found that specific protein patterns on their genome play an important role in determining which one they develop into. These proteins, known as histones, act as switches that control how the […]

Twin study highlights importance of both genetics and environment on gene activity

New research highlights the extent to which epigenetic variation is influenced by both inherited and environmental factors. Epigenetic processes affect the expression or activity of genes without changing the underlying DNA sequence and are believed to be one mechanism by which the environment can interact with the genome. Now, an […]

Byproducts of ‘Junk DNA’ Implicated in Cancer Spread

The more scientists explore so-called “junk” DNA, the less the label seems to fit. Only an estimated two percent of the human genome encodes for functional proteins that carry out normal biological processes. The remaining approximately 98 percent—the “junk DNA”—has for many years been considered a useless artifact. Some junk […]
