摘要
Objective: Spinal muscular atrophy results from loss of the survival motor neuron 1 (SMN1) gene and malfunction of the remaining SMN2. We investigated whether valproic acid can elevate human SMN expression in vivo. Methods: Blood was collected from 10 spinal muscular atrophy carriers and 20 spinal muscular atrophy patients treated with valproic acid. Results: Seven of 10 carriers demonstrated increased SMN messenger RNA and protein levels. SMN2 messenger RNA levels were elevated in 7 patients and unchanged or decreased in 13 patients. Interpretation: We provide first proof of the in vivo activation of a causative gene by valproic acid in an inherited disease and discuss strategies of monitoring drug response in patients.
