High-dose green tea extract may create liver damage in people with certain genetic variations

Long-term use of high-dose green tea extract may provide some protection against cancer, cardiovascular disease, obesity and type 2 diabetes, but it also may create liver damage in a small minority of the population.

Revealing the unappreciated role of POLQ in responding to DNA replication stress

Researchers at the Francis Crick Institute, in partnership with Artios, have discovered how an enzyme involved in DNA repair (POLQ) becomes critical to the survival of some tumors when the cancer cells lose the ability to employ a more frequent way of DNA repair.

Breakthrough on the way to new therapeutic strategies

As far as the field of cancer research is concerned, hollow spheres composed of MYC proteins sets the stage. Researchers from Würzburg have found them out and have reported this discovery in the Nature journal.

Launch of stem cells into space to investigate stem cell aging

Lab tests on astronaut Scott Kelly’s blood cells after he returned from a year-long stay aboard the International Space Station (ISS) showed telomeric and pre-leukemic changes.

The influence of genes and small molecules on personal disease risk

Each individual has a unique chemical fingerprint. Small molecules in the blood, like fats or sugars, have a significant impact on how the human body responds to stress, which diseases people are predisposed to, and how serious an illness will be.

3D “mini eyes” provide insight into genetically induced blindness

The development of “mini eyes” by researchers at the UCL Great Ormond Street Institute of Child Health (UCL GOS ICH) has made it possible to study and comprehend the onset of blindness in the rare genetic disease known as Usher syndrome more.

Mitochondria play a crucial role in the regulation of the NF-κB signaling pathway

Mitochondria are highly regarded as the cell's powerhouse. However, these cellular organelles are essential for more than only energy production: Professor Konstanze Winklhofer and her colleagues at Ruhr University Bochum’s Faculty of Medicine have found that mitochondria play an essential role in signal transduction in innate immune pathways.

Revealing the functional significance of DDX41 in great detail

The DDX41 gene encodes the nuclear enzyme DEAD-box-type RNA helicase. Hematopoietic malignancies are caused by DDX41 mutations. However, the mechanism behind the development of this malignancy remains unknown.

Scientists discover how plant roots adapt their shape to maximize water uptake

Researchers have discovered how plant roots adapt their shape to maximise their uptake of water, pausing branching when they lose contact with water and only resuming once they reconnect with moisture, ensuring they can survive even in the driest conditions.

Revealing cancer development in people carrying inherited BRCA1 mutations

Researchers from Weill Cornell Medicine have discovered that people who inherit a mutant copy of the BRCA1 gene may develop mutations and cancer due to error-prone DNA replication and repair.

Role of p53-mediated metabolism in preventing genomic instability

The gene that codes for the protein p53 is most likely the most significant factor in defending human cells against DNA-damaging agents that cause cancer. The protein permits cells to repair DNA damage and so prevents the formation of malignancies, earning it the nickname “guardian of the genome.”

Researchers unravel the role of plant hormones in preventing Striga infestations

As part of a multipronged approach to prevent infestations by the parasitic plant Striga hermonthica, researchers are unraveling the role of plant hormones, known as strigolactones (SLs).

Discovery may help alleviate the increasing global problem of high soil salinity on farmland

To avoid salt in soil, plants can change their root direction and grow away from saline areas. University of Copenhagen researchers helped find out what makes this possible.

UJ scientists find a faster way to screen soil bacteria as potential biologicals

Researchers found a much faster way to screen soil bacteria as potential biostimulants and bio-pesticides.

Conserved vacuolar sorting hub regulates autophagic flux in plants

A “hub and spoke” system allows plant cells to effectively coordinate cellular trafficking, especially for cellular recycling, also known as autophagy. Autophagosomes are specialized vesicles that capture hazardous molecules and transport them to the vacuole, where they are destroyed.

Discovering H2O2 sensing capacity in plants that control immunity

All aerobic organisms produce the molecule hydrogen peroxide (H2O2). When present in low concentrations, it acts as a crucial secondary signal to control a variety of biological processes, including but not limited to plant-microbe interactions, abiotic stress tolerance, pollen tube growth, root hair formation, leaf cell expansion, and Casparian strip formation.

Harsh parenting leads to depression later in life

Strict parenting can influence how the body reads the children’s DNA. These modifications can become “hard-wired” into the DNA of kids who consider their parents to be harsh, enhancing their biological risk for depression in adolescence and later life.

Role of hormones and their receptors in the plant stress response

Crops are frequently subjected to unfavorable growing conditions. Disease, severe temperatures, and saline soils, for example, cause plants to utilize energy to adapt to stress rather than for development.

The influence of fatty acid metabolism on plant immunity

Most people do not realize that fatty acids can be found in a nutritious salad. Although fatty acids, lipids, and fats may seem unappealing, they are essential to human life and to the plants that are consumed.

Spores integrate environmental signals over time

When exposed to starvation and stress, certain bacteria enter a dormant state in which life functions cease. These cells, known as spores, can resist punishing extremes of heat, pressure, and even the extreme conditions of outer space by entering a profound hibernation.
