Alzheimer\u2019s disease (AD) is a chronic and progressive neurodegenerative disease which affects more than 50 million patients and represents 60\u201380% of all cases of dementia. Mutations in the APP gene, mostly affecting the \u03b3-secretase site of cleavage and presenilin mutations, have been identified in inherited forms of AD. Methods. In the present study, we performed a meta-analysis of the transcriptional signatures that characterize two familial AD mutations (APPV7171F and PSEN1M146V) in order to characterize the common altered biomolecular pathways affected by these mutations. Next, an anti-signature perturbation analysis was performed using the AD meta-signature and the drug meta-signatures obtained from the L1000 database, using cosine similarity as distance metrics. Results. Overall, the meta-analysis identified 1479 differentially expressed genes (DEGs), 684 downregulated genes, and 795 upregulated genes. Additionally, we found 14 drugs with a significant anti-similarity to the AD signature, with the top five drugs being naftifine, moricizine, ketoconazole, perindopril, and fexofenadine. Conclusions. This study aimed to integrate the transcriptional profiles associated with common familial AD mutations in neurons in order to characterize the pathogenetic mechanisms involved in AD and to find more effective drugs for AD.<\/jats:p>","DOI":"10.3390\/brainsci12070827","type":"journal-article","created":{"date-parts":[[2022,6,25]],"date-time":"2022-06-25T10:39:13Z","timestamp":1656153553000},"page":"827","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Computational Analysis of Pathogenetic Pathways in Alzheimer\u2019s Disease and Prediction of Potential Therapeutic Drugs"],"prefix":"10.3390","volume":"12","author":[{"given":"Maria Cristina","family":"Petralia","sequence":"first","affiliation":[{"name":"Department of Clinical and Experimental Medicine, University of Messina, 98122 Messina, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5920-4620","authenticated-orcid":false,"given":"Katia","family":"Mangano","sequence":"additional","affiliation":[{"name":"Department of Biomedical and Biotechnological Sciences, University of Catania, Via S.
