Description
The distinction between lymphatic and blood vessels is biologically fundamental. Two immortalized cell lines, which have been widely used as models for endothelial cells of blood vascular origin, are the human microvascular endothelial cell line-1 (HMEC-1) and the telomerase-immortalized microvascular endothelial cell line (TIME). However, analysis of protein expression by flow cytometry revealed expression of lymphatic markers on these cell lines. Furthermore, functional in vitro leukocyte transmigration assays demonstrated deficiencies in several steps of the leukocyte extravasation cascade. Hence we performed this microarray analysis of the gene expression in HMEC-1 and TIME. We then compare the expression profiles to those of published blood- and lymphatic endothelial cells.

Description
Parathyroid hormone (PTH) plays an essential role in regulating calcium and bone homeostasis in the adult, but whether PTH is required at all for regulating fetal-placental mineral homeostasis is uncertain. To address this we treated Pth-null mice in utero with 1 nmol PTH (1-84) or saline and examined placental calcium transfer 90 minutes later. It was found that placental calcium transfer increased in Pth-null fetuses treated with PTH as compared to Pth-null fetuses treated with saline. Subsequently, to determine the effect of PTH treatment on placental gene expression, in a separate experiment, 90 minutes after the fetal injections the placentas were removed for subsequent RNA extraction and microarray analysis.

Description
CD74, a Type II membrane glycoprotein and MHC class II chaperone (Ii), is normally expressed by cells associated with the immune system. CD74 also forms heterodimers with CD44 to generate receptors to macrophage migration inhibitory factor (MIF), a proinflammatory cytokine. Following targeted Cre-mediated deletion of Ikk in IkkDeltaHep mice (a strain highly susceptible to chemically-induced hepatotoxicity and hepatocarcinogenesis), CD74 is abundantly expressed by hepatocytes throughout liver acini (as detected by specific Western blots and immunohistochemical stains); it is not observed in either control IkkF/F hepatocytes or embryonic fibroblasts from Ikk-/- mice. Constitutive CD74 expression in IkkDeltaHep hepatocytes is also accompanied by significantly augmented expression of CD44 and genes associated with antigen processing and host defense. These observations suggest that IkkDeltaHep hepatocytes might directly respond to MIF signaling, accounting partly for the enhanced susceptibility of IkkDeltaHep mice to hepatotoxins and hepatocarcinogens, and also might exhibit unusual immunological properties including antigen presentation.

Description
Multiple transcription factors regulate B cell commitment, which coordinates with myeloiderythroid lineage differentiation. One such factor, NF-kB, has long been speculated to regulate early B cell development; however, this issue remains controversial. IKKa is required for splenic B cell maturation, but not for bone marrow (BM) B cell development. Here, we unexpectedly found defective BM B cell development and an increased myeloiderythroid lineages in kinase-dead IKKa (KA/KA) knock-in mice. Markedly increased cytosolic p100, an NF-kB2 inhibitory form, and reduced nuclear NF-kB p65, RelB, p50, and p52, as well as IKKa, was observed in KA/KA splenic and BM B cells. Several B- and myeloiderythroid-cell regulators, including Pax5, were deregulated in KA/KA BM B cells. Using fetal liver and BM congenic transplants, and IKKa deletion from early hematopoietic cells in mice, this defect was identified as B cell intrinsic and as an early event during hematopoiesis. Re-expression of IKKa, Pax5, or combined NF-kB molecules promoted B cell development, but repressed myeloiderythroid cell differentiation in KA/KA BM B cells. Together, these results demonstrate that IKKa regulates B-lineage commitment via combined canonical and noncanonical NF-kB transcriptional activity to target Pax5 expression during hematopoiesis.
