Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
To understand the underlying cause and mechanisms of embryonic lethality observed in combined loss of E2f7 and E2f8, we compared global gene expression profiles of wild type, germline deleted and sox2-Cre/Cyp19-Cre deleted embryos and placentas.
Publication Title

- Affymetrix Arabidopsis ATH1 Genome Array (ath1121501)
Description
AS1 and AS2 encode MYB related protein and AS2-domain containing protein, respectively and may regulate transcription. These genes are involved in the determination of axes of leaves of Arabidopsis thaliana. To know the gene regulation in the leaf development, expression profile among wild-type, as1 and as2 mutants and AS2 overexpression plants were compaired.
Publication Title
Meta-analyses of microarrays of Arabidopsis asymmetric leaves1 (as1), as2 and their modifying mutants reveal a critical role for the ETT pathway in stabilization of adaxial-abaxial patterning and cell division during leaf development.

- Affymetrix Arabidopsis ATH1 Genome Array (ath1121501)
Description
AS2 encodes a protein containing AS2 domain and epigenetically regulate transcription. RH10 encodes an ortholog of human DEAD-box RNA helicase DDX47. These genes are involved in the formation of axes of leaves of Arabidopsis thaliana. To know the gene regulation in the leaf development, expression profile among wild-type, as2, rh10 and as2 rh10 double mutant plants were compared.

Description
Pseudomonas aeruginosa use quorum-sensing molecules, including N-(3-oxododecanoyl)-homoserine lactone (C12), for intercellular communication. C12 activated apoptosis in mouse embryo fibroblasts (MEF) from both wild type (WT) and Bax/Bak double knock-out mice (WT MEF and DKO MEF that were responsive to C12, DKOR MEF): nuclei fragmented; mitochondrial membrane potential (??mito) depolarized; Ca2+ was released from the endoplasmic reticulum (ER), increasing cytosolic [Ca2+] (Cacyto); caspase 3/7 was activated. DKOR MEF had been isolated from a nonclonal pool of DKO MEF that were non-responsive to C12 (DKONR MEF). RNAseq analysis, qPCR and western blots showed that WT and DKOR MEF both expressed genes associated with cancer, including paraoxonase 2 (PON2), while DKONR MEF expressed little PON2. Adenovirus-mediated expression of human PON2 in DKONR MEF rendered them responsive to C12: ??mito depolarized, Cacyto increased and caspase 3/7 activated. Human embryonic kidney 293T (HEK293T) cells expressed low levels of endogenous PON2, and these cells were also less responsive to C12. Overexpression of PON2, but not PON2-H114Q (no lactonase activity) in HEK293T cells caused them to become sensitive to C12. Because [C12] may reach high levels in biofilms in lungs of cystic fibrosis (CF) patients, PON2 lactonase activity may control ??mito, Ca2+ release from the ER and apoptosis in CF airway epithelia. Coupled with previous data, these results also indicate that PON2 uses its lactonase activity to prevent Bax- and Bak-dependent apoptosis in response to common proapoptotic drugs like doxorubicin, staurosporine but activates Bax- and Bak-independent apoptosis in response to C12. Overall design: Gene expression profiling of mouse embryo fibroblasts from WT and Bax/Bak double knock-out mice (C12 responsive and non-reponsive cell lines).
