There are no available therapies targeting the underlying molecular mechanisms of neurodegenerative diseases. Although chaperone therapies that alleviate endoplasmic reticulum (ER) stress recently showed promise in the treatment of neurodegenerative diseases, the detailed mechanisms remain unclear. We previously reported that mice with central nervous system-specific deletion of Derlin-1, which encodes an essential component for ER quality control, are useful as models of neurodegenerative diseases such as spinocerebellar degeneration. Cholesterol biosynthesis is essential for brain development, and its disruption inhibits neurite outgrowth, causing brain atrophy. In this study, we report a novel mechanism by which chemical chaperones ameliorate brain atrophy and motor dysfunction. ER stress was induced in the cerebella of Derlin-1 deficiency mice, whereas the administration of a chemical chaperone did not alleviate ER stress. However, chemical chaperone treatment ameliorated cholesterol biosynthesis impairment through SREBP-2 activation and simultaneously relieved brain atrophy and motor dysfunction. Altogether, these findings demonstrate that ER stress may not be the target of action of chaperone therapies and that chemical chaperone-mediated improvement of brain cholesterol biosynthesis is a promising novel therapeutic strategy for neurodegenerative diseases.

Histone acetyltransferases (HATs) are separated into two types. Type A HATs act on nucleosomal histones and thus primarily function in transcriptional regulation, while cytoplasmic HATs (type B) are known as enzymes that modify free histones before their assembly into chromatin, and may also function outside the nucleus. N-alpha-acetyltransferase 60 (NAA60) is the most recently discovered type B HATs, which are also known as N-terminal acetyltransferases (NATs) and are found only in multicellular eukaryotes. NAA60 localizes to the Golgi complex and possesses a unique ability to catalyze the acetylation of membrane-anchored proteins at the N-terminus and free histones at the lysine side chains, the biological significance of which remains unclear. To investigate the cellular functions of NAA60 and its relation to other cytoplasmic HATs, Hat1, we generated <i>NAA60-</i> or <i>HAT1-</i>deficient cells and <i>NAA60/HAT1-</i>double deficient cells using a chicken B lymphocyte leukemia DT40 cell line. Although NAA60-deficient cells did not show any impairment in cell growth and showed a slight sensitivity to DNA damage agents, <i>NAA60/HAT1-</i>double deficient cells exhibited an additive increase in sensitivity to methyl methanesulfonate (MMS) and 4-nitroquinoline 1-oxide (4-NQO) when compared to <i>HAT1-</i>deficient cells, which were previously reported to be moderately sensitive to these agents. These results predict that each type B HATs might contribute differently in regulation of repair of chemical induced DNA lesions.
