Non-canonical Notch Signaling Regulates Actin Remodeling in Cell Migration by Activating PI3K/AKT/Cdc42 Pathway
In conclusion, our research results indicate that DAPT activates PI3K/AKT/Cdc42 signaling by non-canonical Notch pathway, and the activated Cdc42 promotes the filopodia formation and inhibits lamellipodia assembly, resulting in reduced migration of breast cancer cells. The results imply that non-canonical Notch signaling may play a very important role in the rapid response of cells to the extracellular signals.

Melatonin enhances arsenic trioxide-induced cell death via sustained upregulation of Redd1 expression in breast cancer cells
Publication date: Available online 27 November 2015 Source:Molecular and Cellular Endocrinology Author(s): Sun-Mi Yun, Sang Hyeok Woo, Sang Taek Oh, Sung-Eun Hong, Tae-Boo Choe, Sang-Kyu Ye, Eun-Kyu Kim, Min Ki Seong, Hyun-A Kim, Woo Chul Noh, Jin Kyung Lee, Hyeon-Ok Jin, Yun-Han Lee, In-Chul Park Melatonin is implicated in various physiological functions, including anticancer activity. However, the mechanism(s) of its anticancer activity is not well understood. In the present study, we investigated the combined effects of melatonin and arsenic trioxide (ATO) on cell death in human breast cancer cells. Mela...

Abstract 3573: Novel G protein-coupled receptor targets in HER2+ breast cancer
Conclusion: In summary, functional knockdown screening and differential gene expression of GPCRs is a powerful tool for identifying GPCRs as candidate targets in BC. Using the combination of these two approaches, we have discovered that melatonin MT1 receptor as a potential drug target in HER2+ BC cells. The place in therapy for MT1 receptor antagonists, however, still remains to be determined.Citation Format: Raksha Bhat, Puja Yadav, Pavel Christiny, Rachel Schiff, Meghana V. Trivedi.
