Description
Pompe disease is a genetic disorder resulting from a deficiency of lysosomal acid alpha-glucosidase (GAA) that manifests as a clinical spectrum with regard to symptom severity and rate of progression. In this study, we used microarrays to examine gene expression from the muscle of two cohorts of infantile-onset Pompe patients to identify transcriptional differences that may contribute to the disease phenotype. We found strong similarities among the gene expression profiles generated from biceps and quadriceps, and identified a number of signaling pathways altered in both cohorts. We also found that infantile-onset Pompe patient muscle had a gene expression pattern characteristic of immature or regenerating muscle, and exhibited many transcriptional markers of inflammation, despite having few overt signs of inflammatory infiltrate. Further, we identified genes exhibiting correlation between expression at baseline and response to therapy. This combined dataset can serve as a foundation for biological discovery and biomarker development to improve the treatment of Pompe disease.

Description
Neural stem cells (NSC) with self-renewal and multipotent properties serve as an ideal cell source for transplantation to treat spinal cord injury, stroke, and neurodegenerative diseases. To efficiently induce neuronal lineage cells from NSC for neuron replacement therapy, we should clarify the intrinsic genetic programs involved in a time and place-specific regulation of human NSC differentiation. Recently, we established an immortalized human NSC clone HB1.F3 to provide an unlimited NSC source applicable to genetic manipulation for cell-based therapy. To investigate a role of neurogenin 1 (Ngn1), a proneural basic helix-loop-helix (bHLH) transcription factor, in human NSC differentiation, we established a clone derived from F3 stably overexpressing Ngn1. Genome-wide gene expression profiling identified 250 upregulated genes and 338 downregulated genes in Ngn1-overexpressing F3 cells (F3-Ngn1) versus wild-type F3 cells (F3-WT). Notably, leucine-rich repeat-containing G protein-coupled receptor 5 (LGR5), a novel stem cell marker, showed a robust increase in F3-Ngn1.

Description
The dermal papilla plays a key role in the regulation of the hair biology. Accordingly, human dermal papilla cells (hDPCs) may be functionally impaired in female pattern hair loss. A previous observation that beta-estradiol (E2) increased hair density in ovariectomized mice suggested that E2 might modulate the biological properties of hDPCs. Therefore, to further explore the effect of E2 on hDPCs, a global gene expression analysis was conducted.

Description
Dietary collagen hydrolysate has been conjectured to improve skin barrier function. To investigate the effect of long-term collagen hydrolysate administration on the skin, we evaluated stratum corneum water content and skin elasticity in intrinsic aged mice. Female 9-week-old hairless mice were fed a control diet, or a collagen hydrolysate-containing diet, for 12 weeks. The stratum corneum water content and skin elasticity were sequentially decreased by chronological aging in control mice. Intake of collagen hydrolysate significantly suppressed such changes. Moreover, we comprehensively analyzed gene expression in the skin of mouse, which had been administered collagen hydrolysate, using DNA microarray. Twelve weeks after start of collagen intake, no significant differences appeared in gene expression profile compared to that of control group. However, 12 weeks after administration, 135 genes were up-regulated and 448 genes were down-regulated in collagen group compared to control group. It is indicate that gene changes preceded changes of barrier function and elasticity. We focused on several genes correlated with functional changes in the skin. Gene Ontology terms, especially related to epidermal cell development, were signicantly enriched in up-regulated genes. These skin function-related genes had properties that facilitate epidermal production and differentiation and suppress dermal degradation. Thus, dietary collagen hydrolysate induced positive gene changes. In conclusion, our results suggest that alteration of gene expression at early stages after collagen administration affect skin barrier function and mechanical properties. Long-term oral intake of collagen hydrolysate improves skin dysfunction by regulating genes related to production and maintenance of the skin tissue.

Description
Pancreatic islet transplantation was performed in the subcutaneous space of diabetic nude mice. In order to promote long survival and function of transplanted islets a plasma-based scaffold was developed in combination with fibroblasts as graft-supporting accesory cells. Gene expression analysis was carried out to evaluate expression differences due to the presence of fibroblast which could explain the long-term glycemic control observed under these circumstances.
