FADS1 and Alzheimer disease: Microarray experiments revealed 12 genes (BCL2, CDX1, CYP27B1, ENTPD5, MAL, PRIMA1, PTGDR, PTGS2, SFRP1, SOCS3, SULT1A1, and TIMP1) with significantly different transcriptional activities in AD compared to NAT controls, while 6 genes (ALDH1A3, COL1A2, FADS1, SFRP1, SULF1, and THBS2) showed unique gene expression alterations only in CRC samples.
