Description
Human oviduct serves as a conduit for sperm in the peri-ovulatory phase and to nurture and facilitate transport of the developing embryo en route to the uterus for subsequent nidation during the luteal phase of the cycle. Interactions between the embryo and oviductal epithelial surface proteins and secreted products during the four day embryo transit are largely undefined. Herein, we have investigated gene expression in human oviduct in the early luteal vs. follicular phase to identify candidate genes and biomolecular processes that may participate in maturation and transport of the embryo as it traverses this tissue. Oviductal RNA was isolated, processed, and hybridized to oligonucleotide arrays. Resulting data were analyzed by bioinformatic approaches and revealed that 650 genes were significantly downregulated and 683 genes were significantly upregulated in the luteal vs. follicular phase. Real-time RT-PCR, immunoblot analysis, and immunohistochemistry confirmed select gene expression and cellular protein localization. The data demonstrate downregulation of genes involved in macrophage recruitment, immunomodulation, and matrix-degeneration and upregulation of ion transport and secretions as well as anti-angiogenic and early pregnancy recognition genes in luteal vs. follicular phase oviduct. Together, these data suggest a unique hormonally regulated environment during embryo development, maturation and transport through human oviduct.

Description
Tumor necrosis factor-associated factors 2 and 3 (TRAF2 and TRAF3) were shown to function in a co-operative and non-redundant manner to suppress nuclear factor-B2 (NF-B2) activation, gene expression and survival in mature B cells. In the absence of this suppressive activity, B cells developed independently of the obligatory B cell survival factor, BAFF (B cell activating factor of the tumor necrosis factor family). This constitutive, lineage-specific suppression of B cell survival by TRAF2 and TRAF3 determines the requirement for BAFF to sustain B cell development in vivo. We wished to investigate the effect on gene expression in B cells which lacked the negative regulators TRAF2 and TRAF3, and hence had hyperactive NF-kB2 signalling. As Baff-tg mice display a similar phenotype, and have a genetic modification which acts in the same pathway, yet further up, than TRAF2 and TRAF3, we wished to compare and contrast Baff-tg B cells with TRAF2 and TRAF3 deficient B cells. This analysis should identify genes that are important in B cell survival.
Publication Title
TRAF2 and TRAF3 signal adapters act cooperatively to control the maturation and survival signals delivered to B cells by the BAFF receptor.

Description
Resistance to proteasome inhibitors (PIs) is a ubiquitous clinical concern in multiple myeloma (MM). We proposed that signaling-level responses after PI would reveal new means to enhance efficacy. Unbiased phosphoproteomics after the PI carfilzomib surprisingly demonstrated the most prominent phosphorylation changes on spliceosome components. Spliceosome modulation was invisible to RNA or protein abundance alone. Transcriptome analysis demonstrated broad-scale intron retention suggestive of PI-specific splicing interference. Direct spliceosome inhibition synergized with carfilzomib and showed potent anti-myeloma activity. Functional genomics and exome sequencing further supported the spliceosome as a specific vulnerabilityin myeloma. Our results propose splicing interference as an unrecognized modality of PI mechanism, reveal additional modes of spliceosome modulation, and suggest spliceosome targeting as a promising therapeutic strategy in myeloma. Overall design: We examine 1) gene expression of MM cells in response to PI and 2)alternative splicing in response to PI and comparator chemotherapeutic compound. We further investigate splice factor mechanism in MM cells, by examining alternative splicing in MM with overexpression of wild type and mutant splice factor, SRSF1

Description
To study mechanisms of long bone growth regulation, p21 misexpression was induced in the left hindlimb of mouse embryos using an intersectional approach that requires both Cre and (r)tTA activity. Doxycycline was provided to the pregnant female at embryonic day (E)12.5 to activate the transgene, and embryos were collected at E17.5. Distal femur and proximal tibia growth plates were dissected out, keeping left and right separated, deprived of perichondrium and flash frozen. After RNA extraction, mRNA libraries were prepared and all samples were deep sequenced in parallel Overall design: 6 samples (left and right growth plates from embryos #386, #387, #388) were sequenced in parallel
Publication Title
