In this study, their relationship was further explored, accompanied by the investigation into their effects on the sensitivity of temozolomide (TMZ). The proliferation and apoptosis of U87-MG and U251-MG were detected after Rab18 silencing through CCK8 assay and flow cytometry, respectively. The interaction between Rab18 and VSIG4 was predicted through database and verified by immunoprecipitation assay. The suspicion that whether the sensitivity of glioma to temozolomide was affected by the Rab18-VSIG4 interaction was explored through CCK8 assay. We observed decreased proliferation and increased apoptosis and TMZ sensitivity in U87-MG and U251-MG treated by siRNA-Rab18. Not only was the interaction predicted using database, but also it was confirmed by IP assay. Intriguingly, VSIG4 overexpression effectively reversed above biological process and TMZ sensitivity caused by Rab18 silencing. To conclude, the Rab18-VSIG4 interaction was implicated in the proliferation and apoptosis of glioma, as well as TMZ sensitivity. Targeting the interaction between Rab18 and VSIG4 may help exploit new therapies to enhance TMZ sensitivity for treating patients with glioma.WRKY is one of the largest families of transcription factors in plants. It not only regulates plant growth and development but also participates in the regulation of plant defense against biological and abiotic stresses. In this study, research was aimed to overexpress WRKY39 gene of P. trichocarpa (PtWRKY39) and to identify its important role played in drought and saline-alkali tolerance in tobacco model plant. Under the control of CaMV35S promoter, the overexpression of PtWRKY39 gene was increased to more than 10 times in T3 generation of transgenic tobacco plant. The drought resistance and saline-alkali tolerance were evidenced in over
