In the present study, it was observed that aberrant PDGFB expression is associated with survival rates in patients with estrogen receptor-positive (ER+) breast cancer unlike other subtypes, including PDGFA, PDGFC and PDGFD. Accordingly, the effect of specific PDGF receptor (PDGFR) inhibitors on ER-α+ breast cancer cells was investigated. To block the PDGF-BB signaling pathway, PDGFR inhibitors (sunitinib or ponatinib) were employed. Sunitinib and ponatinib were found to arrest the cell cycle at the G0-G1 phase. In addition, the two PDGFR inhibitors were revealed to significantly inhibit cell growth and decrease the expression of matrix metalloproteinase-1, which is one of the metastasis-related genes. Finally, the combined effects of the two PDGFR inhibitors with tamoxifen were investigated. The results demonstrated that the combination of two PDGFR inhibitors with tamoxifen inhibited the growth of cells more consistently, compared with the effect mediated by tamoxifen alone. Therefore, it is proposed that PDGFR inhibitors, including sunitinib and ponatinib, should be applied effectively to treat ER-α+ breast cancer.Sirtuin 6 (SIRT6) is a member of the third family of longevity proteins (SIRTs) that is involved in the development of different types of cancer. However, the potential role of SIRT6 in clear cell renal cell carcinoma (ccRCC) and its molecular mechanism have not yet been fully elucidated. Therefore, the present study aimed to investigate the association between SIRT6 and ccRCC, and to further examine the underlying mechanism of its effect on ccRCC proliferation, using bioinformatics analysis, and in vitro and in vivo experiments. The results of the present study demonstrated that SIRT6 was upregul
