| 1 | Fragile X Messenger Ribonucleoprotein 1(FMR1), a novel inhibitor of osteoblast/osteocyte differentiation, regulates bone formation, mass, and strength in young and aged male and female mice显示文摘Fragile X Messenger Ribonucleoprotein 1(FMR1)gene mutations lead to fragile X syndrome,cognitive disorders,and,in some individuals,scoliosis and craniofacial abnormalities.Four-month-old(mo)male mice with deletion of the FMR1 gene exhibit a mild increase in cortical and cancellous femoral bone mass.However,consequences of absence of FMR1 in bone of young/aged male/female mice and the cellular basis of the skeletal phenotype remain unknown.We found that absence of FMR1 results in improved bone properties with higher bone mineral density in both sexes and in 2-and 9-mo mice.The cancellous bone mass is higher only in females,whereas,cortical bone mass is higher in 2-and 9-mo males,but higher in 2-and lower in 9-mo female FMR1-knockout mice.Furthermore,male bones show higher biomechanical properties at 2mo,and females at both ages.Absence of FMR1 increases osteoblast/mineralization/bone formation and osteocyte dendricity/gene expression in vivo/ex vivo/in vitro,without affecting osteoclasts in vivo/ex vivo.Thus,FMR1 is a novel osteoblast/osteocyte differentiation inhibitor,and its absence leads to age-,site-and sex-dependent higher bone mass/strength. | Padmini Deosthale Julián Balanta-Melo Amy Creecy Chongshan Liu Alejandro Marcial Laura Morales Julita Cridlin Sylvia Robertson Chiebuka Okpara David J.Sanchez Mahdi Ayoubi Joaquín N.Lugo Christopher J.Hernandez Joseph M.Wallace Lilian I.Plotkin | 2023 | Bone Research2023，11，2： | 0 |
