Affymetrix Arabidopsis ATH1 Genome Array (ath1121501)
Description
Changes ins organellar gene expression trigger retrograde signalling. Prolyl-tRNA synthetase (PRORS1) is located in chloroplasts and mitochondria. Thus, prors1-2 mutants are impaired in chloroplast and mitochondrial gene expression.
Publication Title
Identification of target genes and transcription factors implicated in translation-dependent retrograde signaling in Arabidopsis.

Description
This study presents transcription profiles for mouse axial progenitors, presomitic mesoderm and tailbud mesoderm. During vertebrate embryonic development, the formation of axial structures is driven by a population of stem-like cells (axial progenitors) that reside in a region of the tailbud called the chordoneural hinge (CNH) where. We have compared the CNH transcriptome with those of surrounding tissues and shown that the CNH and tailbud mesoderm are transcriptionally similar, and distinct from the presomitic mesoderm. Amongst CNH-enriched genes are several that are required for axial elongation, including Wnt3a, Cdx2, Brachyury/T and Fgf8, and androgen/estrogen receptor nuclear signalling components such as Greb1.
Publication Title
<i>Greb1</i> is required for axial elongation and segmentation in vertebrate embryos.

Description
X-linked inhibitor of apoptosis (XIAP) is the most potent endogenous caspase inhibitor preventing cell death via caspase-9, -7 and -3 (initiator and executioner caspase pathways). Using short hairpin RNA (shRNA) against XIAP, stably expressed in a parent HCT116 human colon cancer cell line, a series of clones have been developed. XIAP mRNA levels were established by RT-PCR, the four X (XIAP knockdown) clonal cell lines show 82-93% reduction in XIAP mRNA when compared to the four L (luciferase control) cell lines. Immunoblot analysis showed a 67-89% reduction in XIAP protein in X cell lines compared to L. RNA was analysed by microarray and XIAP knockdown was confirmed in 7 probe sets, there was no significant compensation of other IAP family members. XIAP knockdown induced a 2-fold increase in the basal level of apoptosis without modification of caspase 3/7 activity. Finally, XIAP knockdown sensitises cells to radiotherapy by 20%, to recombinant TRAIL by a 3-fold factor, and to paclitaxel and docetaxel by >2 fold factor. Future work should focus on targeted agents such as rhTRAIL in combination with strategies to down regulate XIAP. XIAP antisense is now in clinical development in oncology.
Publication Title
Stable XIAP knockdown clones of HCT116 colon cancer cells are more sensitive to TRAIL, taxanes and irradiation in vitro.

Description
RhoBTB2 is a novel Rho GTPase that undergoes loss, underexpression and mutation in breast and lung cancer. We have shown that we can mimic loss of RhoBTB2 through siRNA treatment of primary cells. We propose to perform comparative microarray analysis of primary lung cells to establish the identification of the gene targets of RhoBTb2 regulation.
Publication Title
The atypical Rho GTPase RhoBTB2 is required for expression of the chemokine CXCL14 in normal and cancerous epithelial cells.
