Lithium chloride suppresses ECM protein levels under TGF-β2 stimulatory conditions. (A) Representative immunoblot and (B) densitometric analysis of ECM proteins from conditioned media of primary human TM cells pretreated for 1 hour with LiCl or NaCl control followed by 24-hour stimulation with 2.5 ng/mL activated, recombinant human TGF-β2 or HCl vehicle. Data are expressed as the mean ± SEM (*P < 0.05; ANOVA, Tukey's HSD post hoc test; n = 6, where “n” refers to the number of independent experiments performed using “n” different human TM cell strains).
