SsnB administration attenuates microRNA 21 (miR21) expression and repression of phosphatase and tensin homolog (PTEN). A: qRT-PCR analysis of miR21 expression of S, SH, and SH+SsnB mouse samples normalized against S (*P < 0.05). B: Western blot analysis of β-actin and PTEN protein levels of S, SH, and SH+SsnB sample 1 and sample 2. C: immunoreactive band analysis of PTEN normalized against β-actin. y-Axis depicts the PTEN-to-actin ratio from S, SH, and SH+SsnB sample1 and sample2 groups (*P < 0.05).
