2017), glaucoma (Lee et al. 2012), and possibly sensorineural hearing loss (Kaheel et al. 2018). Our study measured TDP‐43, known to bind and regulate the processing of transcripts encoding mitochondrial proteins (Izumikawa et al. 2017), within stress granules and found that our experimental secretome reduced the amount TDP‐43 in the granules compared to control cells. This evidence concerns the gene TARDBP and glaucoma.
