Dr. Marnie Rose,

28, who allowed viewers of the reality television series Houston Medical to witness her battle with brain cancer, died Friday in Houston of the disease.

Dr. Rose appeared on the six-week summer series Houston Medical on ABC. The pediatric resident pulled off her wig to reveal that she was not only a doctor but also a patient. As recently as a week ago, family, friends and the show's producers were optimistic as doctors said her brain tumor had shrunk.
