Fig. 8. Schematics recapitulating the different impacts of Galectin 3 expression on mitochondria and ER functioning.
At the ER-mitochondria interface, Galectin-3 (i) prevents excessive mitochondrial fission and preserves the shape and dynamics of the mitochondrial network; (ii) modulates OXPHOS activity; (iii) reprograms selectively the mRNA translation via a partial inhibition of the mTORC1 pathway; (iv) favours an adaptative UPR following ER stress induction.
