Research on Film Title Translation from the Perspective of Polysystem Theory
From the film, we can have access to the customs and cultures of all over the world, and the film title is playing a pioneering role. The more successful the title is, the more attractive it is to the audience. The translation of film titles is more dependent on by audiences in different language and in different cultural backgrounds. Therefore, it is necessary to pay attention to the translation of film titles. This paper intends to study the translation of film titles (Chinese translation of English titles and English translation Chinese titles) through Polysystem theory, and find that culture is an important factor affecting the translation of film titles, in addition to political and patron factors
Mechanotransduction of mitochondrial AMPK and its distinct role in flow-induced breast cancer cell migration
The biophysical microenvironment of the tumor site has significant impact on breast cancer progression and metastasis. The importance of altered mechanotransduction in cancerous tissue has been documented, yet its role in the regulation of cellular metabolism and the potential link between cellular energy and cell migration remain poorly understood. In this study, we investigated the role of mechanotransduction in AMP-activated protein kinase (AMPK) activation in breast cancer cells in response to interstitial fluid flow (IFF). Additionally, we explored the involvement of AMPK in breast cancer cell migration. IFF was applied to the 3D cell-matrix construct. The subcellular signaling activity of Src, FAK, and AMPK was visualized in real-time using fluorescent resonance energy transfer (FRET). We observed that breast cancer cells (MDA-MB-231) are more sensitive to IFF than normal epithelial cells (MCF-10A). AMPK was activated at the mitochondria of MDA-MB-231 cells by IFF, but not in other subcellular compartments (i.e., cytosol, plasma membrane, and nucleus). The inhibition of FAK or Src abolished flow-induced AMPK activation in the mitochondria of MDA-MB-231 cells. We also observed that global AMPK activation reduced MDA-MB-231 cell migration. Interestingly, specific AMPK inhibition in the mitochondria reduced cell migration and blocked flow-induced cell migration. Our results suggest the linkage of FAK/Src and mitochondria-specific AMPK in mechanotransduction and the differential role of AMPK in breast cancer cell migration depending on its subcellular compartment-specific activation
