The expression of MALAT1 in lumbar IDD tissues and the correlation with prognosis of IDD a MALAT1 expression in 10 normal and 37 IDD tissue specimens determined by real-time PCR assays. b MALAT1 expression in 37 IDD tissue specimens was delineated according to the Pfirrmann grading groups (mild n = 21, severe n = 16). c–e The mRNA expression of IL-1β, Collagen II and Aggrecan in 10 normal and 37 IDD tissue specimens was determined using real-time PCR assays. The data are presented as mean ± SD of three independent experiments
