Endoplasmic reticulum (ER) and autophagy are recognized to be one of the mechanisms involving the drug resistance of gastric cancer. The mechanisms of action of JAK2/STAT3 pathway were investigated in AGS cells with drug resistance of 5-fluorouracil (5-FU) by corresponding inhibitors. We firstly analyzed the effects of JAK2/STAT3 inhibitor on the expression of drug resistance genes, autophagy markers, and ER stress-related markers on AGS/5-FU cells by Western blot. Whether JAK2/STAT3 pathway regulated the transcription of ATF6 was investigated through luciferase reporter assay. The expression of LC3B was detected by immunofluorescence assay. Next, ER stress inhibitor and ATF6 overexpression plasmid were respectively used to treat AGS/5-FU cells for analyzing whether JAK2/STAT3 pathway regulated ER stress. The results showed that JAK2 inhibitor or STAT3 inhibitor significantly altered the expression of these proteins and suppressed the activities of ATF6 promoter. Intriguingly, ATP6 overexpression could markedly reverse their effects. Moreover, similar effects to JAK2 inhibitor or STAT3 inhibitor appeared in ER stress inhibitor-treated group. These findings indicated that the involvement of JAK2/STAT3 pathway in regulating ER stress affected the 5-FU resistance of AGS cells and autophagy, which was mediated by ATF6. Targeting JAK2/STAT3 pathway could be a potential approach to decrease the 5-FU resistance of gastric cancer and enhance the sensitivity of gastric cancer to 5-FU.

Sauchinone, a biologically diastereomeric lignan, is isolated from the root of Saururus chinensis and has been widely used for the treatment of various diseases. Recently, sauchinone has been reported to play an anti-cancer role in cancer development under normoxia or hypoxia. However, the specific effects of sauchinone on osteosarcoma (OS) remain unclear. The aim of the present study was to investigate the role of sauchinone in OS progression under hypoxic conditions. The human OS cell lines U2OS and MG-63 were exposed to hypoxia followed by treatment with sauchinone. Cell viability was assessed by the CCK-8 assay. Cell migration and invasion were detected by transwell assays. The expression levels of VEGF, HIF-1α, E-cadherin and N-cadherin were examined by the western blot analysis. Our study showed that OS cell migration and invasion were significantly enhanced by hypoxia. Besides, hypoxic conditions resulted in a remarkable change in the expression of EMT markers. All these effects induced by hypoxia were abrogated by sauchinone treatment. Moreover, sauchinone inhibited hypoxia-induced activation of the sonic hedgehog (Shh) pathway.

Vimentin’s essential functions have recently been clear, so Vimentin-deficient of animals was described as a change of morphology and signaling pathway. Recent research has discovered many vital roles for Vimentin that were previously unknown. VIF emerges as an organizer of many essential proteins involved in movement and cell signaling. The highly dynamic and complicated phosphorylation of VIF seems to be a regulator mechanism for various activities. Changes in IF expression patterns are often linked with cancer progression, especially those leading to enhanced invasion and cellular migration. This review will discuss the function of Vimentin intermediate filaments in normal cell physiology, cell adhesion structures, cell shape, and signaling pathways. The genes interaction and gene network linked with Vimentin will be discussed in more studies.
