| Summary |
Lamins, the major components of the nuclear lamina, have diverse functions in many cellular processes. Despite broad expression, lamins have been implicated in cell type-specific roles in development, aging and disease by regulating gene expression. Yet, due to the lack of in depth lineage-specific functional studies, it remains unclear whether or how lamins regulate cell type-specific functions. Using targeted knockout of lamin B1 in the olfactory sensory neuron lineage, we show that lamin B1 is not required for early stages of olfactory sensory neuron differentiation but is needed for formation of mature neurons that properly respond to odor stimulation. Lamin B1 mutant cells exhibited decreased expression of genes involved in mature neuron function, increased expression of genes atypical of the olfactory lineage and clustered nuclear pore distribution. These results demonstrate that the universally expressed lamin B1 regulates cell type-specific gene expression and terminal differentiation.

| Overall design |
Transcriptome profiles were generated from sorted regenerated olfactory epithelium cells lacking Lamin B1 (Lmnb1) and control (heterozygous cells). Each sample is collected from one mouse. Data are from two experimental groups (G1,G2), each containing a control and a mutant sample. Different groups differ in treatment, parents, age and sex. Within a group, treatment, sample preparation, sequencing, animal sex, age, and parents are the same.
