Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
We hypothesize that gene expression in the CS-exposed lungs of this strain (A/J) of mice would be able to give clues about the molecular mechanism of emphysema development, thus contributing to this phenotype. More specifically, although imbalance in oxidants/antioxidants and proteinase/antiproteinase pathways drives the pathogenesis of COPD, the molecular mechanisms involved in the development of emphysema are poorly understood. In order to test this hypothesis at the gene expression level, we utilized microarray analysis to examine transcriptional differences between CS-exposed and Air-exposed groups of mice.
Publication Title
Cigarette smoke-induced emphysema in A/J mice is associated with pulmonary oxidative stress, apoptosis of lung cells, and global alterations in gene expression.

Description
Pregnancy has been shown to decrease the risk of mammary carcinogenesis in human rretrospective epidemiological studies. In rodents, pregnancy prior to carcinogen administration or after carcinogen challenge has also been shown to reduce the incidence of palpable carcinomas. In this study our objective to determine the underlying genomic signature of the pregnancy and reproductive hormones on the mammary gland that contribute to the protection against mammary gland carcinogenesis.

- Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
Human peripheral blood monocytes (Mo) consist of subsets distinguished by expression of CD16 (FCGRIII) and chemokine receptors. Classical CD16- Mo express CCR2 and migrate in response to CCL2, while a minor CD16+ Mo subset expresses CX3CR1 and migrates into tissues expressing CX3CL1. CD16+ Mo produce pro-inflammatory cytokines and are expanded in certain inflammatory conditions including HIV infection.
Publication Title
Transcriptional profiling reveals developmental relationship and distinct biological functions of CD16+ and CD16- monocyte subsets.

Description
We hypothesize that gene expression in the aging lungs of these two strains of mice are divergent thus contributing to the disparity in the phenotypes. More specifically, (1) Aging DBA/2J mice compared to aging C57BL/6 mice are known to be accelerated in their lung physiology and morphometry; (2) C57BL/6J are known to have longer natural longevity than DBA/2J mice. In order to test these hypotheses at the gene expression level, we utilized microarray analysis to examine transcriptional differences between aging lungs of both strains of mice.
Publication Title

- Affymetrix Mouse Expression 430A Array (moe430a)
Description
We hypothesize that gene expression in the lungs of these differentially-treated mice are divergent thus contributing to the disparity in their phenotypes. More specifically, (1) Effects of Leptin-treatment of ob/ob postnatal mice lungs are known to be volume-dependent from 2 to 10 wks of age, and are independent of the hypometabolism associated with leptin deficiency. ; (2) Leptin is critical to postnatal lung remodeling, particularly related to enlarged alveolar surface area. In order to test these hypotheses at the gene expression level, we utilized microarray analysis to examine transcriptional differences between lungs of leptin or saline-treated ob/ob postnatal mice.

- Affymetrix Mouse Genome 430A 2.0 Array (mouse430a2)
Description
Cutaneous malignant melanoma is among the most deadly human cancers, broadly resistant to most clinical therapies. A majority of patients with BRAFV600E melanomas respond well to inhibitors such as vemurafenib, but all ultimately relapse. Moreover, there are no viable treatment options available for other non-BRAF melanoma subtypes in the clinic. A key to improving treatment options lies in a better understanding of mechanisms underlying melanoma progression, which are complex and heterogeneous. In this study we perform gene expression profilling of highly and poorly malignant melanocytic tumors from genetically engineered mouse models to discover important drivers of cancer progression.

Description
In the present study, we demonstrate that hMSCs migrate toward human keratinocytes as well as toward conditioned medium from cultured human keratinocytes (KCM) indicating that the hMSCs can respond to signals from keratinocytes. Incubation of hMSCs with KCM induced dermal myofibroblast like differentiation characterized by expression of cytoskeletal markers vinculin and F-actin filaments with increased expression of alpha smooth muscle actin. We then examined the therapeutic efficacy of hMSCs in wound healing in two animal models representing normal and chronic wound healing. Accelerated wound healing, as determined by quantitative measurements of wound area, was observed when hMSCs and KCM exposed hMSCs (KCMSCs) were injected near the site of incisional/excisional wounds in nondiabetic athymic and NOD/SCID mice as compared with normal human fetal lung fibroblast WI38 cells or saline control induced wound healing.

Description
Novel prognostic subclasses of high-grade astrocytoma are identified and discovered to resemble stages in neurogenesis. One tumor class displaying neuronal lineage markers shows longer survival, while two tumor classes enriched for neural stem cell markers display equally short survival. Poor prognosis subclasses exhibit either markers of proliferation or of angiogenesis and mesenchyme. Analysis of gene expression data is described in Phillips et al., Cancer Cell, 2006.

Detailed analysis of genome-wide transcriptome profiling in rice root is reported here, following Cr-plant interaction. Such studies are important for the identification of genes responsible for tolerance, accumulation and defense response in plants with respect to Cr stress. Rice root metabolome analysis was also carried out to relate differential transcriptome data to biological processes affected by Cr (VI) stress in rice.
