<i>EFNB1</i> expression is differentially expressed in ERMS patients compared to ARMS patients.

(A) Quantitative RT-PCR showing expression of EFNB1 in a panel of ERMS (RD, 381T, SMS-CTR, Rh6, and 617T) and ARMS (Rh3, Rh5, and Rh30) cell lines and myoblasts (MB) as a reference for normal muscle. (B) Comparison of EFNB1 expression levels between ERMS (n = 66 for the Davicioni study; n = 36 for the Williamson study) and ARMS (n = 65 for the Davicioni study; n = 65 for the Williamson study) subtypes. * indicates p < 0.05. ** indicates p < 0.01. *** indicates p < 0.001. **** indicates p < 0.0001.
