Osteoblast Gene Expression in Response to Bicc1 Knockdown. Mus musculus

We recently identified Bicc1 as a regulator of osteoblast differentiation and bone mass. Bicc1 encodes an RNA-binding protein. Here, we have used siRNA to decrease Bicc1 expression in primary calvarial osteoblasts. Illlumina microarrays were then used to profile global gene expression changes. Overall design: The experiment consisted of 16 total samples in 4 treatment groups (N=4 replicates per treatment). The treatment groups were osteoblasts treated with 1). control scrambled siRNA, 2) Bicc1_1 siRNA, 3) Bicc1_2 siRNA and 3) Bicc1_3 siRNA. Cells were isolated, transfected and 48 hours later RNA was isolated and hybridized to arrays.
