Mitochondrial Unfolded Protein Response | Germain Lab

An area of interest in our laboratory is to understand the role of the mitochondrial heterogeneity in breast cancer progression. Cancer cells are characterized by mutations in both the nuclear and mitochondrial genomes as well as by an oxidative environment. […] More recently however, activation of a distinct UPR in response to the accumulation of misfolded proteins in the lumen of the mitochondria (UPRmt) has begun ... [ReadMore..]

Mitochondria Supply ATP To The ER Through A Mechanism ...

ATP enters the endoplasmic reticulum (ER) lumen through an SLC35B1/AXER-dependentCaATiER mechanism, and ATP usage in the ER renders 'anti-Warburg' effect by increasing ATP regeneration from OxPhos while decreasing glycolysis. Sep 9, 2019 ... We propose that under physiological conditions, increases in cytosolic Ca2+ inhibit ATP import into the ER lumen to limit ER ATP consumption. [ReadMore..]

Caffeine chelates calcium in the lumen of the endoplasmic reticulum

Caffeine Chelates Calcium In The Lumen Of The Endoplasmic Reticulum

Cytosolic Ca2+ signals are often amplified by massive calcium release from the endoplasmic reticulum (ER). This calcium-induced calcium release (CICR) occurs by activation of an ER Ca2+ channel, the ryanodine receptor (RyR), which is facilitated by both cytosolic- and ER Ca … Nov 28, 2018 ... Ca2+-overloaded mitochondria also display a drop of the matrix Ca2+ concentration upon caffeine addition. In contrast, in the cytosol, with a ... [ReadMore..]
