Abstract
Selective autophagy contributes to the degradation of condensates, such as sequestosome 1-bodies, also called p62/SQSTM1-bodies. We showed that endogenous p62 forms gel-like structures, which serve as platforms for autophagosome formation and nuclear factor erythroid 2-related factor 2 (NRF2) activation. Further, p62-mediated NRF2 activation is not cytotoxic, but combination of NRF2 activation with impaired bulk and selective autophagy causes liver injury.
期刊介绍:
For a long time, solid neoplasms have been viewed as relatively homogeneous entities composed for the most part of malignant cells. It is now clear that tumors are highly heterogeneous structures that evolve in the context of intimate interactions between cancer cells and endothelial, stromal as well as immune cells. During the past few years, experimental and clinical oncologists have witnessed several conceptual transitions of this type. Molecular and Cellular Oncology (MCO) emerges within this conceptual framework as a high-profile forum for the publication of fundamental, translational and clinical research on cancer. The scope of MCO is broad. Submissions dealing with all aspects of oncogenesis, tumor progression and response to therapy will be welcome, irrespective of whether they focus on solid or hematological neoplasms. MCO has gathered leading scientists with expertise in multiple areas of cancer research and other fields of investigation to constitute a large, interdisciplinary, Editorial Board that will ensure the quality of articles accepted for publication. MCO will publish Original Research Articles, Brief Reports, Reviews, Short Reviews, Commentaries, Author Views (auto-commentaries) and Meeting Reports dealing with all aspects of cancer research.
