Gene therapy with a new base editing technique restores hearing in mice
Using a new genetic engineering technique, known as base editing, researchers from Boston Children’s Hospital and the Broad Institute of MIT and Harvard, have restored hearing in mice with a known recessive genetic mutation. Key takeaways· This is the first example of repairing a recessive gene mutation.· Repairing a single mutation in the Tmc1 gene restored partial hearing in ...

Tracking an organism’s development, cell by cell
A new mouse model allows scientists to track every cell in the body — from the embryo stage until adulthood. The system is the first of its kind and should yield a greater understanding of development, aging, and disease. Scientists described it last week in the journal Cell. “The dream of many developmental biologists for ... Read More about Tracking an organism’s development, cell by cell
Disulfiram inhibits inflammatory gatekeeper protein: Could it be helpful in COVID-19?
Inflammation is the alarm system by which cells first respond to potential danger. But in excess, inflammation can be deadly. In new research from the Program in Cellular and Molecular Medicine (PCCM) at Boston Children’s Hospital, scientists discovered that disulfiram, an FDA-approved drug commonly used for treating alcoholism, blocks a key gatekeeper protein involved in ...

A drug treatment for telomere diseases?
For years, Donna Martin carried a piece of scrap paper with the words “dyskeratosis congenita,” which she believed might explain her son Brad’s sudden, mysterious affliction. A routine blood test had revealed Brad’s bone marrow was failing, unable to keep up with his need for healthy blood cells. His condition, Donna knew, would worsen over ...

Gasdermin E: A new approach to cancer immunotherapy
Tumors have figured out various ways to prevent the immune system from attacking them. Medicine, for its part, has fought back with cancer immunotherapy. The major approach uses checkpoint inhibitors, drugs that help the immune system recognize cancer cells as foreign. Another method, CAR T-cell therapy, directly engineers peoples’ T cells to efficiently recognize cancer ... Read More about Gasdermin E: A new approach to cancer immunotherapy
Designing a coronavirus vaccine for next year – and the years beyond
As the number of coronavirus infections swell daily across the globe, strategies for developing a safe and effective vaccine are rapidly moving forward. In response to this public health crisis, the Precision Vaccines Program (PVP) at Boston Children’s Hospital is on the front lines of developing a coronavirus vaccine targeted especially toward older populations, those ...

Gene therapy reverses heart failure in mouse model of Barth syndrome
Barth syndrome is a rare metabolic disease caused by mutation of a gene called tafazzin or TAZ. It can cause life-threatening heart failure and also weakens the skeletal muscles, undercuts the immune response, and impairs overall growth. Because Barth syndrome is X-linked, it almost always occurs in boys. There is no cure or specific treatment. ... Read More about Gene therapy reverses heart failure in mouse model of Barth syndrome
Mouse model could lead to new treatments for endometriosis pain
There are few effective long-term treatments for endometriosis; even fewer options for relieving the often severe pain associated with the condition, which involves tissue overgrowth outside of the uterus. As a first step toward identifying new pain treatments, researchers in the laboratory of Michael Rogers, PhD, in the Vascular Biology Program at Boston Children’s Hospital, ...

Mouse/human model provides new way to study neuroblastoma
Neuroblastoma is a rare childhood cancer affecting about 800 children each year in the United States. Because of its unusual behavior — tumors in infants often disappear spontaneously without treatment while it can be aggressive and fatal in toddlers — studying the disease has been complicated. That may change with a new research tool: a ... Read More about Mouse/human model provides new way to study neuroblastoma
