Affymetrix Human Gene 1.0 ST Array (hugene10st)
Description
Characteristic extinguishing of B-cell phenotype in cHL is believed to be a result of transcription factor network deregulation due to the overexpression of repressor proteins ID2 and ABF-1. KLF4 is a versatile transcription factor, participating in regulation of differentiation processes in various tissues. Epigenetic silencing of KLF4 in cHL hints that KLF4 is involved in the complex mechanism of extinguishing of B-cell phenotype in cHL.
Publication Title
KLF4 is a tumor suppressor in B-cell non-Hodgkin lymphoma and in classic Hodgkin lymphoma.

- Affymetrix Mouse Gene 1.0 ST Array (mogene10st)
Description
The macrolide rapamycin is known for its immunosuppressive properties since it inhibits mTOR (mammalian target of rapamycin), which activity affects differentiation and functions of various innate and adaptive immune cells involved in graft-versus-host disease development. Since rapamycin procures immunosuppressive effects on the immune response, rapamycin is an attractive candidate for graft-versus-host disease prevention after allogeneic bone marrow transplantation
Publication Title
Rapamycin-based graft-versus-host disease prophylaxis increases the immunosuppressivity of myeloid-derived suppressor cells without affecting T cells and anti-tumor cytotoxicity.

Description
The macrolide rapamycin is known for its immunosuppressive properties since it inhibits mTOR (mammalian target of rapamycin), which activity affects differentiation and functions of various innate and adaptive immune cells involved in graft-versus-host disease development. Since rapamycin procures immunosuppressive effects on the immune response, rapamycin is an attractive candidate for graft-versus-host disease prevention after allogeneic bone marrow transplantation. Recently, an activating effect of rapamycin on the function of myeloid-derived suppressor cells (MDSCs), a subset of immune suppressive cells of myeloid origin was reported. However, the effect of rapamycin treatment on MDSCs induction and function in the management of graft-versus-host disease is largely unknown.

Description
A congenic mouse line was constructed by introgressing a C3H chromosome 9 region harboring Ath29 into the C57BL/6 apoE-deficient background. RNA was extracted from aorta using a QIAGEN kit . Total RNA was pooled in an equal amount from 3 mice for each group. Standard Affymetrix procedures were performed using 8ug of total RNA.

Description
The alimentary tract contains a diffuse endocrine system comprising enteroendocrine cells that secrete peptides or biogenic amines to regulate digestion, insulin secretion, food intake, and energy homeostasis. Lineage analysis in the stomach revealed that a significant fraction of endocrine cells in the gastric corpus did not arise from neurogenin3-expressing cells, unlike enteroendocrine cells elsewhere in the digestive tract. We aimed to isolate enriched serotonin-secreting and enterochromaffin-like (ECL) cells from the stomach and to clarify their cellular origin. We used Neurod1 and Neurog3 lineage analysis, and examined differentiation of serotonin-producing and ECL cells in stomach tissues of Neurod1-cre;ROSAtdTom, Tph1-CFP, c-Kitwsh/wsh, and Neurog3Cre;ROSAtdTom mice, by immunohistochemistry. We used fluorescence-activated cell sorting to isolate each cell type for gene expression analysis. We performed RNA-seq analysis of ECL cells. Neither serotonin-secreting nor ECL cells of the corpus arose from cells expressing Neurod1. Serotonin-secreting cells expressed a number of mast cell genes, but not genes associated with endocrine differentiation; they did not develop in c-Kitwsh/wsh mice and were labeled with transplanted bone marrow cells. RNA-seq analysis of ECL cells revealed high expression levels of many genes common to endocrine cells including transcription factors, hormones, ion channels, and solute transporters but not markers of bone marrow cells. Overall design: We used fluorescence-activated cell sorting to isolate Hdc+ cells from stomach corpus and performed RNA-seq for gene expression analysis to determine the origin of those cells.

Description
Aberrant expression of cancer genes and non-canonical RNA species is a hallmark of cancer. However, the mechanisms driving such atypical gene expression programs are incompletely understood. Here, our transcriptional profiling of a cohort of 50 primary clear cell renal cell carcinoma (ccRCC) samples from The Cancer Genome Atlas (TCGA) reveals that transcription read-through beyond the termination site is a source of transcriptome diversity in cancer cells. Amongst the genes most frequently mutated in ccRCC, we identified SETD2 inactivation as a potent enhancer of transcription read-through. We further show that invasion of neighbouring genes and generation of RNA chimeras are functional outcomes of transcription read-through. We identified the BCL2 oncogene as one of such invaded genes and detected a novel chimera, the CTSC-RAB38, in 20% of ccRCC samples. Collectively, our data highlight a novel link between transcription read-through and aberrant expression of oncogenes and chimeric transcripts that is prevalent in cancer. Overall design: RNA-seq of SETD2 mutant and wild-type ccRCC cell lines.

Description
Osteoarthritis (OA) of the hand is a common disease resulting in pain and impaired function. The pathogenesis of hand OA (HOA) is elusive and models to study it have not been described so far. Culture of chondrocytes is a model to study the development of cartilage degeneration, which is a hallmark of OA and well established in OA of the knee and hip. In the current study we investigated the feasibility human chondrocyte culture derived from proximal interphalangeal (PIP) finger joints of dissecting room cadavers. Index and middle fingers without signs of osteoarthritis were obtained from 30 cadavers using two different protocols. Hyaline cartilage from both articulating surfaces of the proximal interphalangeal (PIP) joint was harvested and digested in collagenase. Cultured chondrocytes were monitored for contamination, viability, and expression of chondrocyte specific genes. Chondrocytes derived from knee joints of the cadavers were cultured under identical conditions. Gene expression comparing chondrocytes from PIP and knee joints was carried out using Affymetrix GeneChip Human 2.0 ST arrays. The resulting differentially expressed genes were validated by real-time PCR and immunohistochemistry.Chondrocytes harvested up to 101 hours after death of the donors were viable. mRNA expression of collagen 2A1, aggrecan and Sox9 was significantly higher in chondrocytes as compared to cultured fibroblasts. Comparison of gene expression by chondrocytes from PIP and knee joints yielded 528 differentially expressed genes. Chondrocytes from the same joint region had a higher grade of similarity than chondrocytes of the same individual. These results were validated using real-time PCR and immunohistochemistry.We demonstrate for the first time a reliable method for culture of chondrocytes derived from PIP joints. PIP chondrocytes show a specific gene expression pattern and could be used as tool to study cartilage degeneration in HOA.
