CRISPR/Cas method could help save rice crops threatened by climate change

A review of gene editing techniques suggests that the CRISPR/Cas (clustered regularly interspaced short palindromic repeats/Cas) method could be a possible 'savior' for rice crops threatened by climate change and high food demand.

Regulatory T cells produced in the gut play a role in repairing injured muscles

The human immune system is incredibly versatile. Among its most skilled multitaskers are T cells, known for their role in everything from fighting infection to reining in inflammation to killing nascent tumors.

Uncovering the complete 3D structure of p53 protein

By inducing cell repair or self-destruction, the tumor suppressor protein p53, often known as “the guardian of the genome,” shields the body’s DNA from daily stress or long-term damage.

Researchers provide an entirely new perspective on tissue oxygenation

Cardiovascular medicine, hematology and pulmonary medicine may soon have the first-ever therapies to correct poor tissue oxygenation, a key driver of disease in millions, including peripheral artery disease, sickle cell disease, heart failure, stroke, emphysema and many others.

Study explores factors associated with parents' acceptance of SGM adolescents using PrEP

Since its approval in 2012, HIV pre-exposure prophylaxis, or PrEP, has shown promise in reducing HIV infection rates by preventing infection in high-risk HIV-negative people. However, research shows that only around three percent of sexual and gender minority (SGM) adolescents who are eligible for PrEP have used it.

Novel way to block the death of nerve cells in MND

Scientists have found a novel way to block the transportation of mutant RNA and subsequent production of toxic repeat proteins which lead to the death of nerve cells in the most common subtypes of motor neurone disease (MND) and frontotemporal dementia (FTD).

Researchers find methods to awaken and revive neural stem cells

Some areas of the adult brain contain quiescent, or dormant, neural stem cells that can potentially be reactivated to form new neurons. However, the transition from quiescence to proliferation is still poorly understood. A team led by scientists from the Universities of Geneva (UNIGE) and Lausanne (UNIL) has discovered the importance of cell metabolism in this process and identified how to wake up these neural stem cells and reactivate them. Biologists succeeded in increasing the number of new neurons in the brain of adult and even elderly mice. These results, promising for the treatment of neurodegenerative diseases, are to be discovered in the journal Science Advances.

Novel framework provides solutions to evade detoxification networks

Scientists at St. Jude Children's Research Hospital have demonstrated how drug makers can avoid two key problems: toxicity and resistance. The researchers made slight changes to a small molecule to reduce its metabolism and elimination by the cellular detoxification network regulated by the pregnane X receptor (PXR). This research provides a framework to develop solutions to the long-standing issue of how to evade detoxification networks using medicinal chemistry. The findings were published today in Proceedings of the National Academy of Sciences.
