Then, 1986: Stuart H. Orkin, MD, examines the DNA sequence of a gene.

Now, 2017: Today, Orkin is associate chief of Hematology/Oncology and chairman of Pediatric Oncology at Dana-Farber/Boston Children’s Cancer and Blood Disorders Center (DF/BC). In this photo, he examines a rendering of a gene regulatory molecule’s structure. Orkin’s lab investigates gene regulation of stem cell development, genetic vulnerabilities to cancer and gene and other therapies for treating hemoglobin disorders.

New cancer target, let-7, unifies theories on neuroblastoma’s origins

Striking the nerve tissue, neuroblastoma is the most common cancer in infants and toddlers. Great strides have been made in its treatment, but advanced cases still are often fatal, and children who survive often face life-long physical and intellectual challenges related to their treatment.

A study published online by Nature last week, led by researchers at Dana-Farber/Boston Children’s Cancer and Blood Disorders Center, finds that a microRNA called let-7 is central in curbing neuroblastoma. The study unifies several theories about neuroblastoma and could bring focus to efforts to find a targeted, nontoxic alternative to chemotherapy.

The findings also have implications for other solid tumors in which let-7 is lost, such as Wilms tumor, lung, breast, ovarian and cervical cancers, says first author John Powers, PhD, of the Division of Pediatric Hematology/Oncology at Boston Children’s Hospital.
