Lin28b Identified As a Key Gene Responsible for Childhood Cancers
The gene, normally expressed only in a developing embryo, was found expressed in several different childhood cancers.
Cancer Cell
Researchers at the Children’s Medical Center Research Institute at UT Southwestern (CRI) have identified a gene that contributes to the development of several childhood cancers, in a study conducted with mice designed to model the cancers. If the findings prove to be applicable to humans, the research could lead to new strategies for targeting certain childhood cancers at a molecular level. The study was published today in the journal .
"We and others have found that Lin28b — a gene that is normally turned on in fetal but not adult tissues – is expressed in several childhood cancers, including neuroblastoma, Wilms’ tumor and hepatoblastoma, a type of cancer that accounts for nearly 80 percent of all liver tumors in children,” said Dr. Hao Zhu, a principal investigator at CRI, and Assistant Professor of Pediatrics and Internal Medicine at UT Southwestern Medical Center. “In our study, we found that overproduction of Lin28b specifically causes hepatoblastoma, while blocking Lin28b impairs the cancer’s growth. This opens up the possibility that pediatric liver cancer patients could one day be treated without resorting to chemotherapy.”
