Abstract

Pogostone (PO), a major component of Pogostemon cablin, displays potent protective effects against lipopolysaccharide-induced acute lung injury (ALI) in mice. This study aimed to investigate the protective effect of PO on TNF-α-induced cell injury in human alveolar epithelial cells in vitro and its underlying mechanism. The cell viability was measured using the MTS method. The cell apoptosis was determined using flow cytometry. The activities of reactive oxygen species (ROS) were detected using a fluorescence microscope. The pro-inflammatory cytokines and antioxidant genes were assessed using reverse transcription-polymerase chain reaction. The protein expression of Kelch-like ECH-associated protein 1 (Keap1), nuclear factor erythroid 2-related factor 2 (Nrf2), nuclear factor of kappa light polypeptide gene enhancer in B-cells inhibitor-alpha (IκBα), and nuclear factor-kappa B (NF-κB) p65 was analyzed using the Western blot analysis. PO alleviated cell apoptosis and inhibited ROS production. It alleviated TNF-α-induced cell injury, suppressed the levels of inflammatory cytokines [interleukin (IL)-6, IL-1β, and IL-8], and enhanced the expression of antioxidant genes (quinine oxidoreductase 1, glutamate cysteine ligase catalytic subunit, heme oxygenase-1). It increased the expression of Keap1 and promoted the activation of Nrf2. However, the phosphorylation of IκBα and the nuclear expression of NF-κB p65 decreased. The anti-inflammatory and antioxidant effects of PO were abrogated following Nrf2 and NF-κB p65 knockdown. The results indicated a protective effect of PO against TNF-α-induced cell injury in A549 cells by modulating the balance between Nrf2 and NF-κB p65 signaling pathways. They verified PO as a promising anti-inflammatory adjuvant drug for treating ALI.

Abstract

Ethnophamacological relevance: Pogostemon cablin is a medicinal herb widely used to treat gastrointestinal diseases in many Asian countries. Pogostone is an important constituent of Pogostemon cablin, and possesses various bioactivitys. In this study, we performed to investigate the anti-colorectal tumor property of Pogostone by inducing aurophagy and apoptosis in human colorectal cancer cells, and to define the potential molecular mechanisms.
Materials and methods: In vitro, The anti-tumor activity of pogostone was assessed using MTT assay. Autophagy was monitored by transmission electron microscopy observation and mRFP-GFP-LC3 fluorescence analysis in colorectal tumor cell line. Apoptosis was measured by flow cytometry and annexinV-FITC/PI staining. The protein expressions or activition of LC3-Ⅱ, AKT, mTOR, caspase-3 and caspase-7 were detected through western blotting. In vivo, the anti-tumor effect of pogostone was tested with HCT116 colorectal tumor cells transplantation tumor model. The expression of Ki-67 was determined by Immunohistochemistry staining and the apoptosis was evaluated using TUNEL assay.
Results: In vitro, pogostone exhibits significant anti-tumor activity against human cancer cell lines, especially for HCT116 (18.7±1.93μg/ml). Transmission electron microscopy observation, mRFP-GFP-LC3 fluorescence analysis, flow cytometry and assay and western blotting detection revealed that the anti-colorectal tumor activity of pogostone was dependent on inducing autophagy and apoptosis through up-regulating the expression of LC3-Ⅱ, cleaved caspase-7 and caspase-3, and decreasing the phosphorylation of AKT/mTOR. In vivo, 150mg/kg pogostone inhibited the HCT116 tumor growth in immunodeficient mice with an inhibitory rate of 43.3%, decreased the expression of Ki67, and induced apoptosis in three days.
Conclusion: Pogostone showed anti-colorectal tumor effects by inducing autophagy and apoptosis involving PI3K/Akt/mTOR axis. Thus, pogostone may be a promising lead compound to be further developed for cancer therapy.

Abstract

Pogostemonis Herba, known as “Guang-Huo-Xiang” in Chinese, has been widely used in the treatment of gastrointestinal dysfunction. Pogostone is one of the major constituents of Pogostemonis Herba. The aim was to scientifically evaluate the possible gastroprotective effect and the underlying mechanisms of pogostone against indomethacin-induced gastric ulcer in rats. Rats were orally treated with vehicle, lansoprazole (30 mg/kg) or pogostone (10, 20 and 40 mg/kg) and subsequently exposed to acute gastric lesions induced by indomethacin. Gross evaluation, histological observation, gastric mucosal superoxide dismutase activity, glutathione content, catalase activity, malonaldehyde level and prostaglandin E2 production were performed. Immunohistochemistry and reverse transcription polymerase chain reaction for cyclooxygenase-1 and cyclooxygenase-2, as well as terminal deoxynucleotidyltransferase-mediated dUTP nick-end labeling assay, immunohistochemistry for heat-shock protein 70, B-cell lymphoma-2 and Bax were conducted. Results indicated that rats pretreated with pogostone showed remarkable protection from the gastric mucosa damage compared to vehicle-treated rats based on the ulcer index and inhibition percentage. Histologically, oral administration of pogostone resulted in observable improvement of gastric injury, characterized by reduction of necrotic lesion, flattening of gastric mucosa and alleviation of submucosal edema with hemorrhage. Pogostone pretreatment significantly raised the depressed activities of superoxide dismutase, glutathione and catalase, while reduced the elevated malonaldehyde level compared with indomethacin-induced group. Pogostone-pretreated group induced a significant increase in gastric mucosal prostaglandin E2 level and obvious up-regulation of protein levels and mRNA expressions of cyclooxygenase-1 and cyclooxygenase-2. Furthermore, antiapoptotic effect of pogostone was verified by terminal deoxynucleotidyltransferase-mediated dUTP nick-end labeling assay, and the apoptotic process triggered by pogostone involved the up-expression of heat-shock protein70 and B-cell lymphoma-2 protein, and suppression of Bax protein expressions in the ulcerated tissues. It is speculated that the gastroprotective effect of pogostone against indomethacin-induced gastric ulceration might be associated with its stimulation of cyclooxygenase-mediated prostaglandin E2, antioxidant and antiapoptotic effect.
