Description
Estrogens are well known steroid hormones necessary to maintain bone health. In addition, mechanical loading, which estrogen signaling may intersect with the Wnt/-catenin pathway, is also essential for bone health. As osteocytes are known as the major mechanosensory cells embedded in mineralized bone matrix, osteocyte ER deletion mice (EROcy/Ocy) were generated by mating ER floxed mice with Dmp1-Cre mice to determine functions of ER in osteocytes. Trabecular bone mineral density of female, but not male EROcy/Ocy mice was significantly decreased. Bone formation parameters in EROcy/Ocy were significantly decreased while osteoclast parameters were unchanged. This suggests that ER in osteocytes exerts osteoprotective function by positively controlling bone formation. To identify potential targets of ER, gene array analysis of Dmp1-GFP osteocytes FACS sorted from EROcy/Ocy and control mice was performed. Expression of Mdk and Sostdc1, both known inhibitors of Wnt, were significantly increased without alteration of the mature osteocyte marker Sost or -catenin. Hindlimb unloading exacerbated the trabecular bone loss, but surprisingly cortical bone was resistant. These studies show that ER in osteocytes has osteoprotective effects in trabecular bone through regulating expression of Wnt antagonists, but conversely plays a negative role in cortical bone loss due to unloading.

Description
To investigate the evolutionary divergence of transcriptional regulation between the mouse subspecies, we performed transcriptome analysis by microarray on testes from the X-chromosome substitution strain, which carries different subspecies-derived X chromosome on the host subspecies genome. Transcription profiling showed that large-scale aberrations in gene expression were occurred on the introgressed X chromosome. This improper expression was restored by introducing chromosome 1 from the same donor strain as the X chromosome, suggesting that the genetic incompatibility between trans-acting regulatory gene(s) on chromosome 1 and X-linked downstream genes might be a cause of the misregulation.

Description
We investigated whether in vitro expansion of human alveolar epithelial type II cells is possible. We found that human endogenous human alveolar epithelial type II cells can be cultured and passaged. The culture system enabled retroviral gene transduction into human alveolar epithelial type II cells. We performed RNA sequencing of human alveolar epithelial type II cells transduced with mutant surfactant protein C or control vector. Overall design: Cultured human alveolar epithelial type II cells were transfected with retroviral vector containing mutant surfactant protein C or control retroviral vector. The retroviral vector contained LNGFR as a marker. After gene transduction, transduced cells were purified by magnetic-activated cell sorting. The transcriptome of the cells was generated by 5'Tag-seq using Ion Genestudio S5 Sequencer.
