FYN promotes breast cancer progression through epithelial-mesenchymal transition

2135 views | Mar 29 2018

Xie YG et al. found that FYN was overexpressed in breast cancer and overexpression of FYN promoted cell proliferation, migration and invasion in the MCF10A cells, whereas depletion of FYN suppressed cell proliferation, migration and invasion in the MDA-MB-231 cells. Moreover, FYN upregulated the expression of mesenchymal markers and epithelial-mesenchymal transition (EMT)-related transcription factors, and downregulated the expression of epithelial markers, suggesting that FYN induces EMT in breast cancer cells. Furthermore, FYN was transcriptionally regulated by FOXO1 and mediated FGF2-induced EMT through both the PI3K/AKT and ERK/MAPK pathways. [Read the Full Post]

Co-inhibition of EGFR and IGF1R synergistically impacts therapeutically on adrenocortical carcinoma

725 views | Mar 25 2018

Xu L et al. showed a significant over-expression of EGFR (66.67%) and IGF1R (80.0%) in ACC. Besides, the co-overexpression of EGFR and IGF1R was seen in 8/15 ACCs, as compared with ACAs (P<0.05). Erlotinib and NVP-AEW541 significantly inhibited cell viability and induced apoptosis by blocking phosphorylation of MEK/ERK and AKT, respectively. Meanwhile, we found that single inhibition of IGF1R induced compensatory activation of MEK/ERK, leading to sustained activation of mTOR, which represent as aggregation of EGFR and IGF1R downstream components. More importantly, the combination of Erlotinib and NVP-AEW541 enhances anti-tumour efficacy compared to treatment with either agent alone or to untreated control in vitro and vivo.
