Comparative expression data of PD21 Pik3cd+/- and Pik3cd-/- female mice ovaries responsed to exogenous gonadotropins.

ABSTRACT: The Pik3cd null females are subfertile and have less growing follicles than their heterozygous littermates in the ovary. These mice poorly respond to the exogenous gonadotropins and ovulate much less oocytes than controls. In addition, the estrodial stimulated GC proliferation in preantral follicles is also impaired in Pik3cd null ovaries. FSH and E2 dramatically activates PI3K/AKT pathway in GCs of wild type mice, but not in the Pik3cd null mice. we used microarray to identify those genes regulated by Pik3cd in response to PMSG (Pregnant Mare Serum Gonadotropin) and E2 treatment in ovary.

In addition, the estrodial stimulated GC proliferation in preantral follicles is also impaired in Pik3cd null ovaries.

We set 3 treatment groups of both Pik3cd+/- and Pik3cd-/- female mice, including PD21 untreatment, PD21 after PMSG administration for 44 hours, PD21 after E2 administration for 72 hours, each group contained three biological repeats. The genes up/down-regulated significantly (not less than 2 fold change) in Pik3cd+/- mice after PMSG and E2 treatment were listed out as PMSG or E2 target genes, in which, those had not the same change trends in Pik3cd-/- were considered as Pik3cd-dependent genes.

Transcriptome analyses of ovarian stroma: tunica albuginea, interstitium and theca interna

Project description:The ovary has specialized stromal compartments, including the tunica albuginea, interstitial stroma and theca interna, which develops concurrently with the follicular antrum. To characterize the molecular determinants of these compartments, stroma adjacent to preantral follicles (pre-theca), interstitium and tunica albuginea were laser microdissected (n = 4 per group) and theca interna was dissected from bovine antral follicles (n = 6).

Distribution and function of 3',5'-Cyclic-AMP hydrolysing phosphodiesterases in the human ovary

Project description:The aim of the study was to describe and characterise the phosphodiesterases in the human ovary. Part of the study included results from analysis of mRNA microarray data from follicles and granulosa cells from three previously published studies(E-MEXP-3783, E-MTAB-2203, E-MTAB-1670). In addition, we used data from two unpublished studies with granulosa cells isolated from 4-6 mm antral follicles and preantral follicles. The included studies covered the folliculogenesis from the preantral stage to after induction of ovulation. For comparison, previously published dataset from heart (E-GEOD-22253, E-MEXP-2654), parietal cortex (E-GEOD-35977), cerebellum (E-GEOD-35974), lung (E-GEOD-43458), and peripheral blood mononucleated cells(E-GEOD-23832) were included in addition to various tissues from Affymetrix's sample data set.

Autosomal recessive PIK3CD deficiency

Project description:We studied a case with suspected PIK3CD deficiency with a homozygous mutation in the patient in PIK3CD (c.1340-1 G>A). All other family members were tested and defined as carriers of the same mutation and are clinically healthy. The literature states that there is an AD but also an AR form of the disease (Immunodeficiency 14 A and B, respectively) linked to the gene. The clinical phenotype of the patient fits very well the description as LOF she suffers from severe, recurrent infections since infancy and has low overall IgG levels.

The long non-coding RNA PIK3CD-AS2 promotes lung adenocarcinoma progression via YBX1-mediated suppression of p53 pathway

Project description:The underlying mechanisms of long non-coding RNAs (lncRNA) participating in the progression of lung cancers are largely unknown. We found a novel lncRNA, PIK3CD antisense RNA 2 (PIK3CD-AS2), that contributes to lung adenocarcinoma (LUAD) progression. The expression characteristics of PIK3CD-AS2 in LUAD were analyzed using microarray expression profile, The Cancer Genome Atlas (TCGA) and Gene Expression Omnibus (GEO) datasets, and validated in 92 paired LUAD tissues by chromogenic in situ hybridization. Our data confirmed that PIK3CD-AS2 expression is a crucial regulator of LUAD progression and associated with shorter patient survival. In vitro studies showed that PIK3CD-AS2 increased cell growth and slowed apoptosis in p53wt cells but not in p53null cells. Mechanically, it is demonstrated that PIK3CD-AS2 bound to and maintained the stability of Y-box binding protein 1 (YBX1), a potent destabilizer of p53, by impeding its ubiquitination and degradation. Downexpression of YBX1 reversed PIK3CD-AS2-mediated inhibition of p53 signaling. Additionally, the therapeutic effect evaluation of a Locked Nuclear Acid (LNA) specifically targeting PIK3CD-AS2 showed an anti-tumor activity in mice with A549 cells xenograft and p53 wild-type LUAD patient-derived tumor xenograft (PDTX) model. Clinically, the high expression of PIK3CD-AS2 showed a poor disease-free survival in p53 wild-type patients in TCGA database. Our findings suggest that PIK3CD-AS2 regulates LUAD progression and elucidate a new PIK3CD-AS2/YBX1/p53 signaling axis, providing a potential lncRNA-directed therapeutic strategy especially in p53 wild-type LUAD patients.

Transcriptomic profiling of bovine ovarian cortical tissue cultured with FSH

Project description:The objective of this study was to determine the transcriptomic effects of FSH stimulation in the bovine ovarian cortical tissue, including responses elicited by the preantral follicles within. Genes whose change in expression between groups was associated with FDR < 0.05 were considered differentially expressed genes (DEG). Results showed after 4 days of culture, there were 34 DEG between FSH- and vehicle-treated ovary; of those, 28 genes were upregulated and 6 were down-regulated in response to FSH. Time-course gene expression analysis identified 252 genes that changed over time in FSH- compared to the vehicle-treated ovary.

Gene expression profiling of ovaries collected from wild type (WT) mice and progesterone receptor (PR) knock out mice

Project description:Previous studies have shown that PR is a critical regulator of ovulation. The PR-null mice (PRKO) failed to ovulate due to a failure in the rupture of the preovulatory follicles. To experimentally induce ovulation, the wild type and PR null mice (C57BL/6, 24–28 d old) were injected ip with 5 IU of PMSG and 48 h later by 5 IU of hCG. Ovaries were collected at 11 h and total RNA was analyzed using Affymetrix mouse arrays

Identification of differentially expressed genes between control and PIK3CD GOF human activated transitional B cells

Project description:IL-21 induces B cell activation, and differentiation into antibody-secreting plasmblasts in vitro. This process is compromised in transitional B cells to gain of function mutations in PIK3CD We used microarrays to identify genes that are differentiatlly expressed following CD40L/IL-21 stimulation of human transitonal B cells from healthy donors and patients with GOF mutations in PIK3CD
