1 Naringenin prevents TGF-beta1 secretion from breast cancer and suppresses pulmonary metastasis by inhibiting PKC activation. naringenin transforming growth factor, beta 1 Mus musculus
2 We have previously demonstrated that naringenin significantly reduced TGF-beta1 levels in bleomycin-induced lung fibrosis and effectively prevented pulmonary metastases of tumors. naringenin transforming growth factor, beta 1 Mus musculus
3 This raised the question of whether naringenin can block TGF-beta1 secretion from breast cancer cells and inhibit their pulmonary metastasis. naringenin transforming growth factor, beta 1 Mus musculus
4 The mechanism whereby naringenin decreases TGF-beta1 secretion from breast cancer cells was investigated at different levels, including Tgf-beta1 transcription, mRNA stability, translation, and extracellular release. naringenin transforming growth factor, beta 1 Mus musculus
5 Administration of the TGF-beta1 blocking antibody 1D11 or naringenin showed an inhibition of pulmonary metastasis for both 4T1/TGF-beta1 tumors and 4T1/RFP tumors, resulting in increased survival of the mice. naringenin transforming growth factor, beta 1 Mus musculus
6 Further experiments revealed that naringenin had no effect on Tgf-beta1 transcription, mRNA decay or protein translation, but prevented TGF-beta1 transport from the trans-Golgi network by inhibiting PKC activity. naringenin transforming growth factor, beta 1 Mus musculus
7 CONCLUSIONS: Naringenin blocks TGF-beta1 trafficking from the trans-Golgi network by suppressing PKC activity, resulting in a reduction of TGF-beta1 secretion from breast cancer cells. naringenin transforming growth factor, beta 1 Mus musculus
8 CONCLUSIONS: Naringenin blocks TGF-beta1 trafficking from the trans-Golgi network by suppressing PKC activity, resulting in a reduction of TGF-beta1 secretion from breast cancer cells. naringenin transforming growth factor, beta 1 Mus musculus
9 This finding suggests that naringenin may be an attractive therapeutic candidate for TGF-beta1 related diseases. naringenin transforming growth factor, beta 1 Mus musculus
