DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).

Gene editing can trigger inflammatory, senescence-like responses in blood stem cells

Scientists at the San Raffaele Telethon Institute for Gene Therapy (SR-Tiget), Milan, have found that gene editing using CRISPR-Cas9 in combination with AAV6 vectors can trigger inflammatory and senescence-like responses in blood stem cells, compromising their long-term ability to regenerate the blood system.

Mass treatment with the antibiotic azithromycin may lead to increased drug resistance

Efforts to reduce child mortality in Africa via mass treatment with the antibiotic azithromycin (AZM) may lead to increased drug resistance in bacteria that frequently cause pneumonia and meningitis, highlighting the need for careful monitoring, finds a new study led by UCL.

Early camizestrant therapy keeps advanced breast cancer in check

Switching to camizestrant, a next-generation oral SERD, significantly prolongs progression-free survival and maintains quality of life in patients with ESR1-mutated, hormone receptor-positive advanced breast cancer. The proactive, biomarker-guided approach allows earlier intervention and may redefine standard care.

Canine DNA study uncovers new genes linked to gastric cancer

Dogs share our homes, our habits and sometimes, our diseases. Gastric cancer is rare in dogs, but when it does strike, it closely resembles gastric cancer in humans: subtle clinical signs, comparable tumor subtypes, late-stage diagnosis and poor outcomes.

Scientists uncover how a single gene shaped the course of plague pandemic

Scientists have documented the way a single gene in the bacterium that causes bubonic plague, Yersinia pestis, allowed it to survive hundreds of years by adjusting its virulence and the length of time it took to kill its victims, but these forms of plague ultimately died out.
