- 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
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.

Description
Variant late-infantile (vLINCL) and juvenile neuronal ceroid lipofuscinosis (JNCL) share clinical and pathological features, including lysosomal accumulation of mitochondrial ATP synthase subunit c, but the unrelated CLN6 and CLN3 genes may initiate disease via similar or distinct cellular processes. To gain insight into the NCL pathways, we established murine wild-type and vLINCL CbCln6nclf cerebellar cells and compared them to wild-type and JNCL CbCln3ex7/8 cerebellar cells. CbCln6nclf/nclf cells and CbCln3ex7/8/ex7/8 cells both displayed abnormally elongated mitochondria and reduced cellular ATP levels and, as cells aged to confluence, exhibited accumulation of subunit c protein in Lamp 1-positive organelles. However, at sub-confluence, endoplasmic reticulum PDI immunostain was decreased only in CbCln6nclf/nclf cells, while fluid-phase endocytosis and LysoTracker labeled vesicles were decreased in both CbCln6nclf/nclf and CbCln3ex7/8/ex7/8 cells, though only the latter cells exhibited abnormal vesicle subcellular distribution. Furthermore, unbiased gene expression analyses revealed only partial overlap in the cerebellar cell genes and pathways that were altered by the Cln3ex7/8 and Cln6nclf mutations. Thus, these data support the hypothesis that vLINCL and JNCL mutations trigger distinct processes that converge on a shared pathway, which is responsible for proper subunit c protein turnover and neuronal cell survival.
