Abstract

Objective To investigate the inhibitory effect of cisplatin (DDP) combined with tunicamycin (TM) on human neuroblastoma SH-SY5Y and SK-N-SH cells and related mechanism. Methods Human neuroblastoma SH-SY5Y and SK-N-SH cells were divided into control group, TM group (treated with 0.4 mg/L TM for 24 h), DDP group (treated with 4 mg/L DDP for 24 h), and DDP+TM group (treated with 0.4 mg/L TM and 4 mg/L DDP for 24 h). CCK-8 assay, plate colony formation assay, scratch assay, and Transwell assay were used to measure the viability and proliferation, migration, and invasion abilities of cells in each group, and Western blotting was used to measure the expression levels of the JAK2-STAT3-HIF1α pathway-related proteins such as JAK-2, p-JAK2, STAT3, p-STAT3, and HIF1α in each group of cells. Results Experimental results showed that compared with the other three groups, the DDP+TM group had significantly lower viability, proliferation and invasion abilities, migration ability at 12 and 24 h, and expression levels of the JAK2-STAT3-HIF1α pathway-related proteins (tLSD=2.14-78.95,P

Abstract

Objective To investigate the effect of the regulator of ribosome synthesis 1 (RRS1) gene on the proliferation and migration of breast cancer BT549 cells and its mechanism of action. Methods Western blot was used to measure the protein expression of RRS1 in human breast cancer cell lines (MDA-MB-231, MDA-MB-468, BT549, and MCF-7 cells) and normal human breast epithelial MCF-10A cells, and immunofluorescence assay was used to observe the localization of RRS1 in BT549 cells. The lentivirus infection method was used to establish an RRS1-knockdown BT549 cell line, and quantitative real-time PCR and Western blot were used to measure the relative mRNA and protein expression levels of RRS1 in the Con group transfected with negative control lentivirus and the sh-RRS1 group transfected with shRNA-RRS1 lentivirus. CCK8 assay and colony-forming assay were used to observe the effect of RRS1 on the proliferation ability of BT549 cells, and wound healing assay and Transwell assay were used to observe the effect of RRS1 on the migration ability of BT549 cells. Western blot was used to measure the relative expression levels of AKT-mTOR signaling pathway proteins and their downstream proteins hypoxia-inducible factor 1α (HIF-1α) and vascular endothelial growth factor (VEGF) in the two groups. Results The relative expression level of RRS1 in breast cancer cell lines MDA-MB-231, MDA-MB-468, BT549, and MCF-7 was significantly higher than that in normal human breast epithelial MCF-10A cells (F=48.92,P
