A high throughput, high content screen for non-toxic small molecules that reduce levels of the nuclear lamina protein, Lamin B1.

ABSTRACT: Lamin B1 (LMNB1) is an intermediate filament protein that is an integral component of the nuclear lamina, a structure that is critical for nuclear organization and function. Mutations involving the lamin B1 gene cause the adult-onset demyelinating disorder, Autosomal Dominant Leukodystrophy (ADLD) which is charactered by increased lamin B1 expression. Increased LMNB1 expression is also associated with poorer outcomes in multiple cancer subtypes. Reducing LMNB1 is thus an attractive therapeutic pathway for ADLD and potentially other diseases. Here we present the results of a high throughput / high content screen (HTS/HCS) to identify small molecules that reduce LMNB1 levels. Approximately 97,000 molecules were screened using an inducible mouse fibroblast model of LMNB1 overexpression that w
