Bone marrow mutation spectra of control and BaP treatments.
► Lrp5 G171V High Bone Mass mutation protected against bone loss with disuse but increased bone response to loading.
The importance of adequately functioning autophagy for normal osteoclast differentiation is apparent in Paget's Disease of Bone, where mutations in the ubiquitin binding protein p62/SQSTM1 results in aberrant osteoclastogenesis [5].
Additionally, the high-bone-mass mutation (G171V) of the Wnt coreceptor LRP-5 has been reported to cause an increase in Wnt activity in osteoblasts by reducing the number of targets for paracrine DKK-1 to antagonize without affecting the activity of autocrine Wnt [ 87], yet its role in neurons remains to be determined.
To further test the accuracy of our NGS data, we compared the control and BaP-induced bone marrow lacZ mutation spectrum with published mutation spectra for transgene reporters from control and BaP-treated mice.
Query #2: 'Find all gene fusion mutations involving the FUS gene with a primary site of bone, and display mutation and sample information' (Table 3).
We have shown that the mutant form of IFITM5 is transcribed into mRNA in bone, and this mutation therefore does not result in an RNA-null allele.
Since inactivating LRP5 (osteoporosis pseudoglioma syndrome) and LRP6 mutations decrease bone mass, whereas activating LRP5 mutations (HBM phenotype) and mutations disrupting SOST expression (sclerosteosis and van Buchem's disease) increase bone mass, WNT signaling must activate bone formation.
The trauma activates the boy's mutation: bone claws protrude from his hands, and he kills Thomas, who reveals that he is James's real father.
Meanwhile, as a specific marker of hypertrophic chondrocytes, the type X collagen gene (COL10A1) is also critical for endochondral bone formation, as mutation and altered COL10A1 expression are often accompanied by abnormal chondrocyte hypertrophy in many skeletal diseases.
