Osteoblast-specific overexpression of menin. A, Col1a1-Menin-Tg transgene construct in which the osteoblast-specific 2.3-kb Col1a1 promoter drives expression of a FLAG-tagged human menin cDNA. β, rabbit β-globin intron; pA, SV40 polyadenylation signal. Arrows indicate positions of forward (F) and reverse (R) primers. B, tissue RNA (calvaria, cartilage, trachea, kidney, liver, and heart) was extracted, and RT-PCR was carried out. The Col1a1-Menin-Tg transgene was expressed specifically in bone in the founder shown. −RT, minus reverse transcriptase control. C, tissue protein (calvaria, femur, cartilage, and kidney) was extracted, and a Western blot was conducted with antibodies against FLAG (Col1a1-Menin-Tg transgene), menin (endogenous and exogenous menin), and β-tubulin (loading control). The transgene (menin) was expressed specifically in bone of the Col1a1-Menin-Tg mice.
