RNA integrity number (RIN) is decreased in Alzheimer’s disease hippocampus: RIN values from RNA extracted from disease affected and unaffected regions were compared between disease groups and neurologically normal cases, as well as across all regions of neurologically normal cases. (A) A significant decrease in RIN was observed in the AD HP. (B) No significant differences in RIN were observed in the CN or CB in HD. (C) No significant differences in RIN were observed in the SN or CB in PD. (D) RIN did not differ by region in normal cases. *p < 0.05.
