Description
The cochlear duct is tonotopically organized, such that the basal cochlea responds more sensitively to high frequency sounds and the apical cochlea to low frequency sounds. In effort to understand how the tonotopic organization is established in mammals, we searched for genes that are differentially expressed along the tonotopic axis during neonatal development.

Description
Because of their small size, nanoparticles that enter the human body can easily penetrate biological barriers and can be circulated throughout the entire body, ultimately reaching the vascular endothelium. In this study aimed to identify cell reponses by distinguishing endothelial cell and exposing them to silver nanoparticles. The study also assesseed several gene expression levels that increased significantly in the microarray assay. We verified through microarray that 5 nm silver nanoparticles affect the variation of gene expression in cells, and a noticeable increase in the expression of interleukin (IL)-8 and IL-11 genes in early time was also verified. This study found that the variation on oxidative stress related genes in early time, amd among them the variation of metallothionein(MT), heme oxygenase 1(HO1), and heat shock 70kDa protein(HSP70) expression, was noticeable.

Description
Multipotent spermatogonial stem cells (mSSCs) derived from SSCs are a potential new source of individualized pluripotent cells in regenerate medicine such as ESCs. We hypothesized that the culture-induced reprogramming of SSCs was mediated by a mechanism different from that of iPS, and was due to up-regulation of specific pluripotency-related genes during cultivation. Through a comparative analysis of expression profile data, we try to find cell reprogramming candidate factors from mouse spermatogonial stem cells. We used microarrays to analyze the gene expression profiles of culture-induced reprogramming converting unipotent spermatogonial stem cells to pluripotent spermatogonial stem cells.

Description
Hematopoiesis is a series of lineage differentiation programs initiated from hematopoietic stem cells (HSCs) in the bone marrow (BM). To maintain lifelong hematopoiesis, the pool of HSCs is precisely maintained by diverse molecular mechanisms. CCCTC-binding factor (CTCF) is a DNA-binding zinc-finger protein which regulates its target gene expression by organizing higher order chromatin structures. Currently, the role for CTCF in controlling HSC homeostasis is unknown. By using a tamoxifen-induced CTCF conditional knockout mouse system, we demonstrate that CTCF is a critical regulator for the homeostatic maintenance of adult HSCs by retaining HSC cell cycle quiescence. Acute systemic CTCF ablation leads to a severe BM failure and rapid shrinkage of multiple c-Kithi progenitor populations, including Sca-1+ HSCs in adult mice. Similarly, a hematopoietic system-confined CTCF depletion elicits an acute loss of HSCs and highly increased mortality. Mixed BM chimeras reconstituted together with the supporting BM reveal that CTCF deficiency-mediated HSC depletion is a cell-autonomous effect. Although c-Kithi myeloid progenitors were severely reduced after ablating Ctcf gene, c-Kitint common lymphoid progenitors and their progenies were less affected by the lack of CTCF. Whole transcriptome analyses show that CTCF deficiency results in an enhanced expression of the cell cycle-promoting program and CTCF-depleted HSCs express higher level of reactive oxygen species (ROS). Importantly, in vivo treatment with the antioxidant partially rescued the c-Kithi population and their quiescence. We conclude that CTCF is a pivotal player in maintaining adult HSC pool likely through regulating ROS-dependent HSC quiescence.
