Langerhans cell histiocytosis study 1 / normal epidermal Langerhans cell sample

Relative Expression (log2-ratio):-2.335103
Number of Samples:7 / 3
Experimental Langerhans cell histiocytosis study 1
Langerhans cell histiocytes (LCH) were isolated from LCH lesions of patients undergoing surgery. All patients had single system disease, five patients had bone lesion, one had skin lesion and one had mucosal manifestation. Langerhans cells histiocytes were purified by FACS as CD1a+ / CD270 + population with > 95% purity.
Control normal epidermal Langerhans cell sample
Normal epidermal Langerhans cells were isolated from skin of healthy adult donors. Single cells were isolated by collagenase digestion from epidermal sheets and CD1a - expressing cells were isolated by FACS purification. Gene-chips were further analyzed for transcripts of potentially contaminating cells - no transcripts for CD3? (T cell), CD19 (B cell) or Desmogleins 1-4 (keratinocytes) were detected, confirming purity of sorted cells.

monocyte activation study 1 (NOD2L/TLR/1L; 6h) / untreated monocyte sample (6h)

Relative Expression (log2-ratio):2.240734
Number of Samples:5 / 5
Experimental monocyte activation study 1 (NOD2L/TLR/1L; 6h)
Monocytes were isolated from five healthy donors, cultured in RPMI with 10% vitamin D?sufficient (100 nM) human serum and activated for 6 hours with 1 ug/ml muramyl dipeptide (nucleotide-binding oligomerization domain-containing protein 2 ligand, NOD2L) and 1 ug/ml mycobacterial 19-kDa triacylated lipopeptide (TLR2/1 ligand, TLR2/1L). This type of activation is via nucleotide-binding oligomerization domain-containing protein 2 (NOD2) and heterodimeric Toll-like receptor 2 and Toll-like receptor 1 (TLR2/1).
Control untreated monocyte sample (6h)

EBNA2 overexpr. study 1 (4h) / control virus transfected EREB2-5 cell sample (24h)

Relative Expression (log2-ratio):2.143199
Number of Samples:3 / 3
Experimental EBNA2 overexpr. study 1 (4h)
EREB2-5 cell line stably transfected with the chimeric Epstein-Barr virus-encoded nuclear antigen 2 (EBNA2) and control expression plasmid coding for bacterial chloramphenicol acetyltransferase (CAT) gene and . CAT was used as a negative control. Briefly, before the CAT and EBNA2 induction, cells were maintained in RPMI media and deprived of estrogen for 3 days before doxycycline and estrogen was added. Expression of EBNA2 was induced after addition of estrogen and expression of CAT was induced by the addition of doxycycline to a final concentration of 100 ng/mL medium. Doxycycline induced cells were harvested 4 hours after induction. Because EBNA2 is essential for the proliferation of EBV-infected cells, EREB2-5 cells grow only in the presence of estrogen. Before the preparation of RNA, NGFR cells were purified by MACS separation to enrich the cells with a transcriptional response to doxycycline.
Control control virus transfected EREB2-5 cell sample (24h)
EREB2-5 cell line stably transfected with control expression plasmid coding for bacterial chloramphenicol acetyltransferase (CAT) gene. CAT was used as a negative control. Briefly, before the CAT induction, cells were maintained in RPMI media and deprived of estrogen for 3 days before doxycycline was added. Expression of CAT was induced by the addition of doxycycline to a final concentration of 100 ng/mL medium. Doxycycline induced cells were harvested 24 hours after induction. Estrogen withdrawal leads to the inactivation of EBNA2, resulting in cell cycle arrest. Before the preparation of RNA, NGFR cells were purified by MACS separation to enrich the cells with a transcriptional response to doxycycline.
