Gene expression in male and female brains become more similar with age, study says

When male and female fruit flies age, their brains become desexualized. Age-related changes take place in both sexes, but the male brain becomes feminized to a larger extent than the female brain becomes masculinized. This is the conclusion of a study performed by a research group at Linköping University. The findings are published in the journal Proceedings of the Royal Society of London B.

New computation-guided approach to identify small molecule corrector drugs for p53 hotspot mutations

A new study, led by researchers from the University of California, Irvine and the University of California, San Diego, reveals a new computation-guided approach to identify small molecules that can restore aspects of wild-type p53 tumor suppression function to mutated p53, which play an important role in many human cancers.

IRB scientists identify critical spots on the genome where gene editing could cause an unwanted response

CRISPR/Cas9 is a commonly used, very precise, gene editing technique whose development, by Jennifer A. Doudna and Emmanuelle Charpentier, was recognised with the 2020 Nobel Prize in Chemistry. Commonly known as "genetic scissors", CRISPR allows the introduction of the desired DNA sequence into (virtually) any spot of the genome, thus modifying or inactivating a gene. This technique is widely used in biomedical research and some CRISPR-based therapies are in clinical trials for the treatment of human blood disorders, some types of cancer and HIV, among other conditions.

Next-generation sequencing system yields results comparable to traditional diagnostics

In the pursuit of accurate diagnoses for illnesses, doctors have traditionally used multiple methods — including culturing patient samples on a wide variety of media, reviewing countless medical records and analyzing clinical data using complex mathematical algorithms — to try to identify the bacterium, virus, fungus or other pathogen responsible for an infection.

Neuronal cilia are important for dopamine receptor 1 signaling, study shows

A historically overlooked rod-like projection present on nearly every cell type in the human body may finally be getting its scientific due: A new study has found that these appendages, called cilia, on neurons in the brain have a key role in ensuring a specific dopamine receptor's signals are properly received.

The eyes of mutant zebrafish help understand the role of a protein in preventing cell death

Around 15 years ago, a group of researchers discovered mutant zebrafish. The eyes of these zebrafish did not develop correctly, resulting in them being significantly smaller than the eyes of wild zebrafish.

Species across the animal kingdom show signs of cognitive impairment with disease

Is brain fog a condition limited to humans? "Infectious disease and cognition in wild populations," a recently published paper in Trends in Ecology & Evolution, answers that question. In a review of the studies, it explores whether learning, memory, and problem-solving are impaired by infection, not just in humans, but in species across the animal kingdom.
