Unlocking the Mysteries of BACE1 and BACE1-AS in Human Diseases

Published on March 21, 2022

Imagine that the brain is a complex puzzle, with each piece playing a crucial role. One important piece is the β-Secretase BACE1, which has been linked to the development of neurodegenerative diseases like Alzheimer’s. We now know that BACE1 is influenced by a long non-coding RNA called BACE1-AS, which acts like a conductor, orchestrating the expression of BACE1. Research suggests that these two players also have implications in other conditions such as Parkinson’s disease and heart failure. By understanding how BACE1 and BACE1-AS interact, scientists hope to uncover new avenues for therapeutic intervention. This groundbreaking research provides a deeper understanding of the complex mechanisms underlying neurodegenerative diseases and brings us closer to finding effective treatments. To learn more about this fascinating subject, dive into the full article!

The β-Secretase (BACE1) is widely studied to be particularly involved in amyloid deposition, a process known as the pathogenic pathway in neurodegenerative diseases. Therefore, BACE1 expression is frequently reported to be upregulated in brain samples of the patients with Alzheimer’s disease (AD). BACE1 expression is regulated by BACE1-AS, a long non-coding RNA (lncRNA), which is transcribed in the opposite direction to its locus. BACE1-AS positively regulates the BACE1 expression, and their expression levels are regulated in physiological processes, such as brain and vascular homeostasis, although their roles in the regulation of amyloidogenic process have been studied further. BACE1-AS dysregulation is reported consistent with BACE1 in a number of human diseases, such as AD, Parkinson’s disease (PD), heart failure (HF), and mild cognitive impairment. BACE1 or less BACE1-AS inhibition has shown therapeutic potentials particularly in decreasing manifestations of amyloid-linked neurodegenerative diseases. Here, we have reviewed the role of lncRNA BACE1 and BACE1-AS in a number of human diseases focusing on neurodegenerative disorders, particularly, AD.
