Slc39a zinc transporter mRNA expression following transient Slc30a8 knockdown in MIN6 cells. Time-course for mRNA expression of Slc30a8, Slc39a1, Slc39a6, Slc39a7, Slc39a8, Slc39a9 and Slc39a14 following knockdown of Slc30a8 by siRNA. Expression was assayed at 48, 72 and 96 h post-transfection. Changes in mRNA abundances were calculated through qPCR and presented as expression ratios relative to MIN6 cells transfected with Silencer® Select negative control siRNA (control) at each time-point. Data were analysed by 2-way ANOVA followed by Sidak’s multiple comparison test. Error bars show ±SEM. n = 3. * p < 0.05, ** p < 0.005, *** p < 0.001.
