Prostate cancer and the unfolded protein response
The endoplasmic reticulum (ER) is an essential organelle that contributes to several key cellular functions, including lipogenesis, gluconeogenesis, calcium storage, and organelle biogenesis. The ER also serves as the major site for protein folding and trafficking, especially in specialized secretory cells. Accumulation of misfolded proteins and failure of ER adaptive capacity activates the unf...
متن کاملThe unfolded protein response
Where does the UPR function? Between the endoplasmic reticulum (ER) and the nucleus of eukaryotic cells. All secreted proteins and proteins that reside in secretory compartments translocate as nascent peptide chains into the ER, where they may undergo folding, modification and assembly before assuming their functional conformations. The ER maintains a specialized oxidizing environment to aid ch...
متن کاملUnfolded protein response
yeasts have rewired many regulatory networks, such that processes as diverse as ribosomal protein gene regulation, galactose metabolism and mating-type switching, which appear to be very similar at the physiological level, are regulated by different transcription factors that bind to different regulatory sequences. Despite its evolutionary distance to S. cerevisiae being relatively short, C alb...
متن کاملThe unfolded protein response.
The endoplasmic reticulum (ER) is a principal site for folding and maturation of transmembrane, secretory and ERresident proteins. Perturbations that alter ER homeostasis can lead to accumulation of unfolded proteins (UPs), which is a threat to all living cells. To cope with the stress, cells activate an intracellular signaling pathway – the unfolded protein response (UPR). The UPR is an integr...
متن کاملEndoplasmic Reticulum Stress, Unfolded Protein Response, and Cancer Cell Fate
Perturbation of endoplasmic reticulum (ER) homeostasis results in a stress condition termed "ER stress" determining the activation of a finely regulated program defined as unfolded protein response (UPR) and whose primary aim is to restore this organelle's physiological activity. Several physiological and pathological stimuli deregulate normal ER activity causing UPR activation, such as hypoxia...
