Based on the findings in this study, suppressing PAI1 expression in VC cells appears to reduce their progression and tumorigenic potential. Therefore, PAI1 could possibly function as an oncogene in VC. GPER1 appears to be a suitable target for suppressing PAI1 in VC.

LINC00665 sponged miR-199b-5p to interact with SERPINE1 expression, resulting in the increase of phosphorylation of AKt, thus participating in the PI3K/AKt pathway. To summarize, LINC00665 facilitated the tumorigenesis and trastuzumab resistance of GC by sponging miR-199b-5p and promoting SERPINE1 expression, which further activated PI3K/AKt signaling; this finding reveals a new mechanism by which LINC00665 modulates tumor development and drug resistance in GC.

Treatment of MCF-7 cells with paclitaxel (PTX), a microtubule-stabilizing antitumor drug, at 1 µM for 2 h elevated the PAI-1 concentration of the conditioned medium at 48 h after treatment but not in those treated with tamoxifen and cyclophosphamide. Microtubule assembly inhibitors vinblastine (VBT) and vincristine (VCT) also increased the PAI-1 concentration in the conditioned medium...This study demonstrated that temporary low-dose treatment with microtubule-associated anticancer drugs increased PAI-1 release from MCF-7 cells but not from MDA-MB-231 cells. These results indicate that chemotherapy against luminal A-type breast cancer using microtubule-associated drugs may cause thrombosis through the inhibition of the fibrinolytic system by PAI-1.

SERPINE1 overexpression is associated with a poor gastric cancer prognosis.

H. pylori infection induces Serpin E1 expression in fibroblasts, subsequently triggering its expression in GC cells through their interaction. Serpin E1 derived from these cells promotes the migration and p38 MAPK/VEGFA-mediated angiogenesis of HUVECs, thereby facilitating GC growth and peritoneal metastasis. Targeting Serpin E1 signaling is a potential therapy strategy for H. pylori-induced GC.
