Affymetrix Human Transcriptome Array 2.0 (hta20)
Description
HnRNPA2B1 encodes an RNA binding protein associated with neurodegenerative disorders. However, its function in the nervous system is unclear. Transcriptome-wide cross-linking and immunoprecipitation in mouse spinal cord discover UAGG motifs enriched within ~2,500 hnRNP A2/B1 binding sites and an unexpected role for hnRNP A2/B1 in alternative polyadenylation. Loss of hnRNP A2/B1 results in alternative splicing, including skipping of an exon in amyotrophic lateral sclerosis (ALS)-associated D-amino acid oxidase (DAO) that reduces D-serine metabolism. Inclusion of the DAO exon is also reduced in transgenic ALS mice models. ALS-associated hnRNP A2/B1 D290V mutant patient fibroblasts and motor neurons differentiated from induced pluripotent stem cells demonstrate gain-of-mutant-dependent splicing differences. Mutant motor neurons also exhibit increased hnRNP A2/B1 localization to cytoplasmic granules during stress, which are abrogated by a small molecule CA43. Our findings and cellular resource identify RNA networks affected in loss of normal and mutated hnRNP A2/B1 with broad relevance to neurodegeneration.

- Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
The liver stages of malaria sporozoites develop in the hepatocyte cytoplasm inside a parasitophorous vacuole (PV). The circumsporozoite (CS) protein, the major surface protein of sporozoites, traverses the PV membrane and enters the cytoplasm and nucleus of hepatocytes. CS export into the cytoplasm requires the presence of pexel/VTS motifs. The transport of CS into the host nucleus is then mediated by importin (Imp) alpha3/beta1 that binds to the nuclear localization signal of CS localized in the conserved region II-plus. The NLSs of CS and of NFkB p50 share the same Imp. The entry of NFkB p50 into the nucleus is strongly inhibited in cell lines expressing CS, and in infected hepatocytes. Micro-array data from CS expressing cell line shows that 40 NFkB targets were significantly down regulated. Among them inflammation related MIP3a and PTGS transcripts were 65 and 22 fold down regulated, thus explaining the notable absence of inflammatory cells surrounding exo-erythrocytic forms (EEFs). The presence of CS in the cytoplasm of hepatocytes enhances EEF growth both in vitro and in vivo. Therefore Plasmodium blood stages and EEFs use the same strategy to secrete proteins into the cytoplasm of host cells and remodel it to the parasites advantage.

Description
Cells are constantly exposed to stress. Most of those stresses do not necessarily cause cell death or visible damage. The present study explores the way the immune system responds to such sub lethal stressed cells.

Description
We hypothesized that the trophoblast secretes anti-angiogenic factors, which increase in late pregnancy to limit angiogenesis. Therefore, we determined the paracrine effect of primary human trophoblasts from early versus late pregnancy on the angiogenic potential of isolated feto-placental endothelial cells.
