Study explains why human mitochondrial genomes mutate frequently

One could say that mitochondria, the energy-producing organelles inside every human cell, dance to their own beat.

TMEM106B gene reveals the causes of neurodegenerative diseases

Across the globe, approximately 50 million people are living with dementia. The two most common forms are Alzheimer's disease and frontotemporal lobar degeneration (FTLD), which develop when neurons in specific parts of the brain stop functioning - triggering memory loss and other behavioral or personality changes.

Metabolomics can help understand the impact of calorie-restricted diets on aging

Changes in a few small molecules involved in a cell's metabolism seem to indicate whether a restricted "life extension" diet will actually extend, shorten, or have no effect on lifespan, a study of fruit flies has found.

Bioinformaticians reveal previously unknown features of genes involved in brain functioning

In a recent study of genes involved in brain functioning, their previously unknown features have been uncovered by bioinformaticians from the Moscow Institute of Physics and Technology and the Institute of Mathematical Problems of Biology, RAS. The findings are reported in PLOS One.

Expansion stress promotes immunosuppression and enhances growth of breast cancer cells

Expansion stress can have an alarming impact on breast cancer cells by creating conditions that could lead to dangerous acceleration of the disease, an interdisciplinary team of University of Alabama at Birmingham researchers has found.

Salmonella biofilm protein can cause autoimmunity and arthritis in animals

Scientists from the Vaccine and Infectious Disease Organization-International Vaccine Centre at the University of Saskatchewan and Temple University have demonstrated that a Salmonella biofilm protein can cause autoimmune responses and arthritis in animals.

Structural analysis of SARS-CoV-2 spike protein offers clues about the virus' evolution

Researchers at the Francis Crick Institute have characterized the structure of the SARS-CoV-2 spike protein as well as its most similar relative in a bat coronavirus. The structures provide clues about how the spike evolved and could help inform vaccine design.

Study shows an entirely new complexity within enzyme machinery

Proteins are the workers in a cell and, as the "basic element of life", are responsible for the most widely varying metabolic processes.

Research uncovers how 'reubiquitination' promotes elimination of misfolded membrane proteins

Chinese researchers recently discovered a protein quality control mechanism called "reubiquitination".

New type of molecular editor can make precise changes in mitochondrial DNA

The genome in mitochondria -- the cell's energy-producing organelles -- is involved in disease and key biological functions, and the ability to precisely alter this DNA would allow scientists to learn more about the effects of these genes and mutations.

Researchers discover how good gut bacteria can help reduce heart disease risk

Scientists have discovered that one of the good bacteria found in the human gut has a benefit that has remained unrecognized until now: the potential to reduce the risk for heart disease.

Super-resolution microscopy methods reveal the smallest cell structures

Theoretically, high-resolution microscopy should make it possible to capture cell structures that have a resolution of a few nanometers.

SOAT1 enzyme offers a promising therapeutic target for pancreatic cancer

Researchers from CSHL have discovered that the growth of pancreatic cancer cells can be stopped by disrupting the way cholesterol is stored by the cells.

Integrating metabolomics and genomics to improve patient diagnosis

A patient and family walk into a doctor's office. They hope that the latest tests will reveal what is causing the patient's illness and end the diagnostic odyssey they have been going through for years.

Scientists discover role of surface diffusion in protein transport

Many of the most promising medicines under development are proteins, often antibodies, to help patients fight disease. These proteins must be purified as part of the manufacturing process -- a task that can be tricky and result in costly waste.

Protein PRC1 acts as a 'viscous glue' during cell division, research shows

An over-abundance of the protein PRC1, which is essential to cell division, is a telltale sign in many cancer types, including prostate, ovarian, and breast cancer.

Animal proteins more effective than plant proteins in building aging muscles

On a gram for gram basis, animal proteins are more effective than plant proteins in supporting the maintenance of skeletal muscle mass with advancing age, shows research presented this week at The Physiological Society's virtual early career conference Future Physiology 2020.
