Enhanced autophagic-lysosomal activity and increased BAG3-mediated selective macroautophagy as adaptive response of neuronal cells to chronic oxidati…

2019

Oxidative stress and a disturbed cellular protein homeostasis (proteostasis) belong to the most important hallmarks of aging and of neurodegenerative disorders. The proteasomal and autophagic-lysosomal degradation pathways are key measures to maintain proteostasis. Here, we report that hippocampal cells selected for full adaptation and resistance to oxidative stress induced by hydrogen peroxide (oxidative stress-resistant cells, OxSR cells) showed a massive increase in the expression of components of the cellular autophagic-lysosomal network and a significantly higher overall autophagic activity. A comparative expression analysis revealed that distinct key regulators of autophagy are upregu…

Expression of the kinetochore protein Hec1 during the cell cycle in normal and cancer cells and its regulation by the pRb pathway.

2010

Highly Expressed in Cancer protein 1 (Hec1) is a subunit of the Ndc80 complex, a constituent of the mitotic kinetochore. HEC1 has been shown to be overexpressed in many cancers, suggesting that HEC1 upregulation is involved in the generation and/or maintenance of the tumour phenotype. However, the regulation of Hec1 expression in normal and tumour cells and the molecular alterations promoting accumulation of this protein in cancer cells are still unknown. Here we show that elevated Hec1 protein levels are characteristic of transformed cell lines of different origins and that kinetochore recruitment of this protein is also increased in cancer cell lines in comparison with normal human cells.…
