Abstract:
Background. Geiparvarin (GN) is a natural compound with anticancer activity. However, the effect of GN on osteosarcoma (OS) and the anticancer mechanism of GN are still unclear. Methods. Cell viability was measured by MTT assay. Invasion and migration were measured by transwell assay. The miRNAs, genes, and signaling pathways affected by GN were confirmed by whole-genome sequencing and bioinformatics analysis. The expression level of mRNA and protein was measured by qRT-PCR and western blot. Animal experiment was performed for confirming the GN anticancer effect and side effect in vivo. Results. Our results show that GN significantly inhibits OS cell growth and metastasis in vitro. In vivo experiment also showed that GN dramatically suppressed OS lung metastasis and no side effects were found. GN treatment inhibited OS metastasis through upregulating the ANGPTL4 expression. In addition, GN inhibited the expression of miR-3912-3p, which targets ANGPTL4. Conclusion. Our data clearly indicate that GN is a candidate drug for OS treatment, and GN plays its role through miR-3912-3p/ANGPTL4 in OS.

Abstract:
Background: Geiparvarin (GN) is a natural compound isolated from the leaves of Geijera parviflora and exhibits anticancer activity. Nevertheless, little is known about its anticancer mechanism and anti-osteosarcoma (OS) effects. Aim: This study explored whether GN effectively inhibits the growth and metastasis of osteosarcoma (OS) through a series of in vitro and in vivo experiments. Methods: Cell proliferation was measured by colony formation and MTT assays, and cell invasion was detected by Transwell assay. Flow cytometry and caspase-3 activity assays were carried out to examine cell apoptosis, and western blot analysis was performed to assess protein expression. In the animal experiments, the changes in relevant indexes were determined by immunohistochemistry and tumor vessel imaging. Results: Animal experiments showed that GN treatment significantly inhibited the growth and lung metastasis of OS, accompanied by increased apoptosis. In addition, GN treatment notably diminished COX2 expression and angiogenesis in OS. Moreover, COX2 overexpression nullified GN-induced decline in angiogenesis, growth, and lung metastasis and increased apoptosis in OS. Of note, the body weight of mice was enhanced after GN treatment, and the pathological examination manifested that GN treatment did not cause any damage to major organs. Conclusion: Our data indicated that GN might depress the growth, metastasis, and angiogenesis of OS by decreasing COX2 expression, suggesting GN is a favorable candidate drug for OS treatment without side effects. Hence, it can be concluded that geiparvarin inhibits OS progression by reducing COX2 expression.
