- Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
Myeloid derived suppressor cells (MDSC) playing the immune suppressive roles in tumor bearing host consists of two major subsets of granulocytic and monocytic cells. Granulocytic MDSC (G-MDSC) express CD11b+ Gr-1high Ly6G+ Ly6Clow and produce high level of reactive oxygen species (ROS). Interestingly, neutrophils are well known ROS producing cells during immune defensive process and share same surface markers with G-MDSC. These similar features always brought the fundamental questions whats the difference between G-MDSC and neutrophils but its not yet proven clearly.
Publication Title
Characterization of the nature of granulocytic myeloid-derived suppressor cells in tumor-bearing mice.

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
Human Whartons jelly stem cells (hWJSCs) are derived ethically in large amounts from the umbilical cord matrix. Besides their differentiation capabilities, WJSCs also display a notable lack of ability to form teratoma. hWJSCs have been shown to exert immunomodulatory effects and have recently been reported to kill or diminish cancer cell growth. These characteristics are important considerations for their use in cell therapy. In this transcriptome analysis, hWJSCs were profiled using Affymetrix DNA microarrays and compared to a panel of human stem cells and stromal cells. Although hWJSCs are multipotent, they expressed very low levels of the majority of stem cell markers, including POU5F1, NANOG, SOX2 and LIN28. BIRC5 has recently been shown to be required for teratoma formation in SCID mice. The lower levels of BIRC5 expression in hWJSCs compared to hESCs and the very low levels of stem cell markers might account for hWJSCs inability to form teratomas. IL12A which is known to be associated with the induction of apoptosis, was amongst the several cytokines identified to be significantly upregulated in hWJSCs. The ability of hWJSCs to compliment the host immune responses was further highlighted with the GO Biological Process analysis showing high association with immune system, chemotaxis and cell death. The ability to modulate immune responses confers hWJSCs an additional advantage in stem cell therapy and potentially allows hWJSCs as a form of treatment for cancer and immune disorders. In summary, the transcriptome profile of hWJSCs has provided indications on the genetic basis for their biological characteristics in immunomodulatory response, anti-cancer effects, and the lack of teratoma formation.
