Missed signals? A new way we vary from each other biologically
Genetics has made huge strides over the past 20 years, from the sequencing of the human genome to a growing understanding of factors that turn genes on and off, namely transcription factors and the DNA “enhancer” sequences they bind to. New research from Boston Children’s Hospital introduces another previously unknown layer of human genetics. It ... Read More
Going ‘all in’ for Khori: New hope for congenital enteropathy
Khori LeBlanc is “one of the sassiest and sweetest kids you’ll ever meet,” says her mom, Bryanna Black. Her good mood even carries over to her many hospital visits, where she can be often be found practicing her “karate” moves on the way to an appointment.

Precision chemo-immunotherapy for pancreatic cancer?
Pancreatic cancer is highly lethal and in great need of better treatments. Only about 10 percent of patients remain alive five years after diagnosis. In a new study, researchers in the lab of Marsha Moses, PhD, at Boston Children’s Hospital offer a glimmer of hope. Key takeaway An antibody-drug combination effectively targeted, penetrated, and shrank ... Read More

This might be something you’d be interested in.” Doctors had just diagnosed a young girl named Mila in Colorado with Batten disease, a rare and fatal neurodegenerative disorder. ... Read More
Small samples, big data: A systems-biology look at a newborn’s first week of life
The first week of a baby’s life is a time of rapid biological change. The newborn must adapt to living outside the womb, suddenly exposed to new bacteria and viruses. Yet scientists know surprisingly little about these early changes. Reporting in Nature Communications, an international research team provides the most detailed accounting to date of the ...

Typing medulloblastoma: From RNA to proteomics and phospho-proteomics
Medulloblastoma is one of the most common pediatric brain tumors, accounting for nearly 10 percent of cases. It occurs in the cerebellum, a complex part of the brain that controls balance, coordination and motor function and regulates verbal expression and emotional modulation. While overall survival rates are high, current therapies can be toxic and cause secondary ... Read More
