Chemo-resistance and metastatic disease development are the most common causes of breast cancer recurrence and death. Thidiazuron (TDZ) is a plant growth regulator, its biological role on human and animals has not been yet clarified. In the present study, we investigated the anticancer activity of this plant phytohormone on the drug resistant-triple negative breast cancer MDA-MB-231 cell line. Treatment of the breast cancer cells with TDZ (1-50 μM) caused more stressful environment and induced a significant increase in percentages of active caspases positive cells. In addition, TDZ treatment (5 and 10 μM) significantly attenuated the migration and the invasion activities of these highly metastatic cancer cells. Mechanistically, TDZ reducesd cancer progression and invasive activity through targeting miR-202-5p, which stimulatesd the expression of the phosphatase and tensin homolog (PTEN), the tumor suppressor that downregulates PI3K/AKT signaling pathway. In the meantime, TDZ treatment statistically upregulatesd the suppressor of breast cancer proliferation, miRNA-132 that is also implicated in dysregulating the TEN-AKT/the nuclear factor NFκB signaling pathway. Interestingly, our molecular docking analysis revealed potential non-covalent interaction between TDZ with AKT, PTEN and PI3K. These findings suggest that TDZ may suppresses breast cancer metastasis through targeting miRNA-132, miR-202-5p/PTEN and PI3K/AKT downstream molecules.

AbstractOxysterol-binding protein like protein 3 (OSBPL3) has been shown involving in the development of several human cancers. However, the relationship between OSBPL3 and colorectal cancer (CRC), particularly the role of OSBPL3 in the proliferation, invasion and metastasis of CRC remains unclear. In this study, we investigated the role of OSBPL3 in CRC and found that its expression was significantly higher in CRC tissues than that in normal tissues. In addition, high expression of OSBPL3 was closely related to poor differentiation, advanced TNM stage and poor prognosis of CRC. Further experiments showed that over-expression of OSBPL3 promoted the proliferation, invasion and metastasis of CRC in vitro and in vivo models. Moreover, we revealed that OSBPL3 promoted CRC progression through activation of RAS signaling pathway. Furthermore, we demonstrated that hypoxia induced factor 1 (HIF-1A) can regulate the expression of OSBPL3 via binding to the hypoxia response element (HRE) in the promoter of OSBPL3. In summary, Upregulation of OSBPL3 by HIF1A promotes colorectal cancer progression through activation of RAS signaling pathway. This novel mechanism provides a comprehensive understanding of both OSBPL3 and the RAS signaling pathway in the progression of CRC and indicates that the HIF1A–OSBPL3–RAS axis is a potential target for early therapeutic intervention in CRC progression.
