Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
Several studies have shown that bone mineral density (BMD), a clinically measurable predictor of osteoporotic fracture, is the sum of genetic and environmental influences. In addition, serum IGF-1 levels have been correlated to both BMD and fracture risk. We previously identified a Quantitative Trait Locus (QTL) for Bone Mineral Density (BMD) on mouse Chromosome (Chr) 6 that overlaps a QTL for serum IGF-1. The B6.C3H-6T (6T) congenic mouse is homozygous for C57BL/6J (B6) alleles across the genome except for a 30 cM region on Chr 6 that is homozygous for C3H/HeJ (C3H) alleles. This mouse was created to study biology behind both the BMD and the serum IGF-1 QTLs and to identify the gene(s) underlying these QTLs. Female 6T mice have lower BMD and lower serum IGF-1 levels at all ages measured. As the liver is the major source of serum IGF-1, we examined differential expression in the livers of fasted female B6 and 6T mice by microarray.

Description
Phosphate is essential for healthy bone growth and plays an essential role in fracture repair. Although phosphate deficiency has been shown to impair fracture healing, the mechanisms involved in impaired healing are unknown. More recently, studies have shown that the effect of phosphate deficiency on the repair process varied based on the genetic strain of mice, which is not characterized.

Description
Heat acclimation (AC) allows its faster re-induction following its decline. Constitutively preserved euchromatin state in hsp70 promoter during acclimation decline/regain pushed forward the hypothesis that acclimation decline is a period of dormant memory involving molecular program including epigenetic controlled transcriptional regulation leading to heat acclimation mediated cytoprotective memory.

- Affymetrix Yeast Genome 2.0 Array (yeast2)
Description
The eukaryotic cytoplasmic chaperonin-containing TCP-1 (CCT) is a complex formed by two back-to-back stacked hetero-octameric rings that assists the folding of actins, tubulins and other proteins in an ATP-dependent manner. Here, we decided to test the significance of the hetero-oligomeric nature of CCT for its function by introducing, in each of the eight subunits in turn, an identical mutation at a position involved in ATP binding and conserved in all the subunits, in order to establish the extent of individuality of the various subunits. Our results show that these identical mutations lead to dramatically different phenotypes. For example, cells with the mutation in CCT2 have an excess of actin patches and are the only pseudo-diploid strain. By contrast, cells with the mutation in CCT7 are the only ones to accumulate juxta-nuclear protein aggregates that may reflect the absence of stress response in this strain. System-level analysis of the strains using RNA microarrays reveals connections between CCT and several cellular networks including ribosome biogenesis and TOR2 that help to explain the phenotypic variability observed
Publication Title
Equivalent mutations in the eight subunits of the chaperonin CCT produce dramatically different cellular and gene expression phenotypes.
