"SB431542 inhibited TGFbeta1 induced SMAD3 phosphorylation and abrogated the small basal expression of pSMAD3 seen in control cultures without exogenous TGFbeta, indicating autocrine activity (XREF_FIG), as the growth medium supplements contained minimal TGFbeta activity and did not account for the baseline activity (XREF_SUPPLEMENTARY)."
reach
"A recent study reports that naringenin significantly inhibits the transcription of SMAD3 induced by TGF-beta1 and reduces the probability of TGF-beta1 binding to its receptor TbetaRII, thereby inhibiting receptor dimerization and downstream signaling transduction, inhibiting cell migration and invasion."
reach
"Confocal immunofluoresence assay with anti-pSmad3 antibody (used to detect levels of Smad3 when phosphorylated at Ser423/425) showed that TGF-beta1 treatment increased pSmad3 levels in VSMCs, especially in the nucleus; and pretreatment with 3AB or PJ34 prevented the TGF-beta1-induced increase (XREF_FIG)."
reach
"Both SFRP1 and FRZB inhibit the TGFbeta1 induced increase of active beta-catenin, but do not influence the TGFbeta1 induced phosphorylation levels of SMAD3, positioning Wnt signaling activity downstream of the active TGFbeta signal in lung fibroblasts, but not in alveolar epithelial cells."
