Objectives : This study is to investigate the anti-aging and antioxidant effects of Naesohwangryeon-tang(NSHRT) extract in Hs68 fibroblasts. Methods : The fibroblast cell line Hs68 cells were used and MTT analysis was performed to measure the cell viability of Naesohwangryeon-tang, and then MMP-1 was induced with the cytokine TNF-𝛼 to confirm the anti-aging effect through real-time PCR and ELISA. In addition, ROS was induced with the TNF-𝛼 to confirm the anti-oxidant effect through DCF-DA. The signaling pathway according to the antioxidant effect was performed by western blot. Results : Naesohwangryeon-tang did not show cytotoxicity at all concentrations(100-800㎍/㎖) treated on Hs68 cells, and the inhibitory effect of MMP-1 was also confirmed. In addition, it was confirmed that the intracellular ROS increased by TNF-α was decreased by Naesohwangryeon-tang, and it was confirmed that the expression of NQO1 was increased in a concentration-dependent manner of Naesohwangryeon-tang. Conclusions : These results suggest that Naesohwangryeon-tang can be used as an anti-aging material by demonstrating the anti-aging and antioxidant effects of Naesohwangryeon-tang.

Objectives: Naesohwangryeon-tang (NHT) is a type of traditional herbal formula, however, little is known about its antitumor activity. In this study, the antitumor properties of NHT was evaluated in human lung adenocarcinoma cells. Methods: To check the inhibitory effect of NHT, MTT assay was performed. Cell cycle analysis and detection of ROS production were conducted by flow cytometry. To evaluate the signaling pathway, Western blotting was conducted. Results: Our results showed that the decrease of cell proliferation by NHT stimulation occurred more significantly in A549 cells than in NCI-H460 cells. In addition, NHT-induced apoptosis was associated with the activation of caspases and production of reactive oxygen species (ROS). NHT-induced apoptosis was attenuated after pretreatments with z-VAD-fmk or N-acetylcysteine, suggesting that NHT-induced apoptosis was caspaseand ROS-dependent. Interestingly, NHT treatment led to the development of autophagic vesicular organelles and upregulation of several autophagy-related genes. The pretreatment of bafilomycin A1 decreased apoptosis slightly but increased cell viability in the presence of NHT. Conclusion: These findings indicated that NHT induces both apoptosis and cell-protective autophagy in human lung cancer cells. This data suggests that NHT might be a novel herbal drug for lung cancer.
