Big smiles and big checks were easy to spot Wednesday afternoon at Duke Children's Hospital and Health Center.
Two doctors received grants for pediatric cancer research.
The money comes from Hyundai's "Hope on Wheels."
Dr. Ashley Hinson received $75,000 and Dr. Corrine Linardic received $250,000.
Dr. Linardic said the money is needed because they no longer get as much from the federal government to continue their research.
"We work on a cancer called rhabdomyosarcoma, which is cancer of connective tissue which has features of skeletal muscle. Some of the kids do great, but there are some high-risk groups that don't do very well and we're really trying to figure out how we can do better with those kids," she said.
Children who are battling cancer came to the event and left painted handprints on a Hyundai Hope on Wheels vehicle and on the labcoats of the two doctors who received the grants.
Since 2005, Duke Childrens Hospital and Health Center has received more than $1.6 million from Hope on Wheels.
Duke is one of 41 recipients and part of $10.5 million in grants awarded this month by Hope on Wheels in recognition of National Childhood Cancer Awareness Month.
