Finally, we observed the downregulation of a serine/arginine-rich splicing factor 3 SRSF3, which seems to be involved in the differential splicing of the low-density lipoprotein receptor (LDLR), a major apolipoprotein E (APOE) receptor that has been associated with cholesterol homeostasis and, possibly, AD development[76]. Here, APOE is linked to Alzheimer disease.
