Khan, Imran Kumar, Neeraj Pant, Ila Narra, Sivakrishna Kondaiah, Paturu Areca nut potentiates TGF-β action on hGF cells. <p>Human gingival fibroblast (hGF) cells were serum deprived by replenishing with medium containing 0.2% serum for 24 h. Subsequently, hGF cells were treated for 72 hours with areca nut water extract (5H− 5 µg/ml) and or TGF-β (5 ng/ml). Real time PCR was used to examine the expression of genes regulated by TGF-β or areca nut extracts (A, B, C, D, E, F, G and H).
