Current Opinion in Cell Biology 

TL;DR: This work has shown that regulation by heterodimerization between Jun, Fos and ATF proteins, AP-1 activity is regulated through interactions with specific protein kinases and a variety of transcriptional coactivators, and there has been considerable progress in understanding some of the mechanisms and signaling pathways involved in the regulation of AP.

TL;DR: Recent advances in the study of mitogen-activated protein kinase cascades include the cloning of genes encoding novel members of the cascades, further definition of the roles of the cascade in responses to extracellular signals, and examination of cross-talk between different cascades.

TL;DR: Exosomes transfer not only membrane components but also nucleic acid between different cells, emphasizing their role in intercellular communication.

TL;DR: Recent advances in identifying and understanding the core molecular machinery and signaling pathways that are involved in mammalian autophagy are highlighted.

TL;DR: Increasing evidence suggests that EMT plays a specific role in the migration of cells from a primary tumor into the circulation and may provide a rationale for developing more effective cancer therapies.
