Abstract

fetched live from OpenAlex

Endoplasmic reticulum (ER) stress is caused by the accumulation of mis/unfolded proteins in the ER. ER stress signalling pathways termed the unfolded protein response are employed to alleviate ER stress through increasing the folding capacity and decreasing the folding demand of the ER as well as removing mis/unfolded proteins. However, ER stress signalling pathways induce diverse cellular changes beyond changes to the ER. This study aims to further investigate some of these ER stress-mediated events. 
\n
\nER stress can cause activation of JNK. Prolonged ER stress-mediated JNK activation is reported to promote apoptosis whilst both acute and long-lasting JNK activation is proposed to cause insulin resistance. To begin with it is reported in this thesis that acute ER stress-induced JNK activation, which is dependent on IRE1α and TRAF2, promotes survival. In contrast to other studies, this thesis provides evidence that acute ER stress-mediated JNK activation does not inhibit insulin signalling during ER stress in several cell lines. However, prolonged ER stress, in four different cell lines, does inhibit insulin signalling in a JNK independent manner. This study argues that ER-stress-induced insulin resistance during prolonged ER stress involves inhibition of trafficking of newly synthesised insulin receptors through the secretory pathway to the plasma membrane. 
\n
\nFinally ER stress can activate inflammatory signalling pathways other than JNK and thus ER stress may promote inflammation. Neuroinflammation and ER stress are reported in Parkinson’s disease (PD) yet a link between them has so far not been investigated. Using a cellular model of PD, it is reported in this thesis that ER stress has the potential to activate neuroinflammation in PD.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
