Reactive astrogliosis is characterized by a profound change in astrocyte phenotype in response to all CNS injuries and diseases. To better understand the reactive astrocyte state, we used Affymetrix GeneChip arrays to profile gene expression in populations of reactive astrocytes isolated at various time points after induction using two different mouse injury models, ischemic stroke and neuroinflammation.

View SamplesEutopic endometrium in endometriosis has molecular evidence of resistance to progesterone (P4) and activation of the PKA pathway in the stromal compartment. To investigate global and temporal responses of eutopic endometrium to P4, we compared early (6-h), intermediate (48-h), and late (14-day) transcriptomes, signaling pathways, and networks of human endometrial stromal fibroblasts (hESFs) from women with endometriosis (hESFendo) to hESFs from women without endometriosis (hESFnonendo). Endometrial biopsy samples were obtained from subjects with and without mild peritoneal endometriosis (n = 4 per group), and hESFs were isolated and treated with P4 (1 M) plus estradiol (E2) (10 nM), E2 alone (10 nM), or vehicle for up to 14 days. Total RNA was subjected to microarray analysis using a Gene 1.0 ST (Affymetrix) platform and analyzed by using bioinformatic algorithms, and data were validated by quantitative real-time PCR and ELISA. Results revealed unique kinetic expression of specific genes and unique pathways, distinct biological and molecular processes, and signaling pathways and networks during the early, intermediate, and late responses to P4 in both hESFnonendo and hESFendo, although a blunted response to P4 was observed in the latter. The normal response of hESF to P4 involves a tightly regulated kinetic cascade involving key components in the P4 receptor and MAPK signaling pathways that results in inhibition of E2-mediated proliferation and eventual differentiation to the decidual phenotype, but this was not established in the hESFendo early response to P4. The abnormal response of this cell type to P4 may contribute to compromised embryonic implantation and infertility in women with endometriosis.

View SamplesAdipose tissue stromal cells contribute to the regulation of adipose tissue in lean and obese states. Myeloid cells such as adipose tissue macrophages (ATMs) and dendritic cells (ATDCs) undergo both quantitative and qualitative changes with obesity. Due to similarity in markers the identify of adipose tissue dendritic cells and macrophages has been elusive. We have refined prior protocols to unambiguously discern ATM and ATDC in mice. We used microarrays to compare the profiles of ATMs and ATDC from gonadal adipose tissue from lean, obese, and formerly obese mice. We also isolated preadipocytes (PA) from lean and obese mice for comparison.

View SamplesTo study differential gene expression of TCLs upon TCR signaling, three TCL primary cells and one TCL cell line T8ML1 were chosen for this study. The prmiary TCL cells consist of TCL1 and TCL2 (sezary patients) and TCL3 (PTCL, NOS patient). The TCR signaling was engaged by anti-CD3/CD28 treatment in vitro. The TCL cells were treated without/with anti-CD3/CD28 for different time periods in vitro in cell culture. The total RNA was isolated from the TCLs and subjected to affimetry microarray (GPL17692) analysis. The differential gene expression of individual TCL was identified as well as a set of common genes invloved in TCR signaling in TCLs.

View SamplesIn the present study, we sought to understand the impact of bariatric surgery [using vertical sleeve gastrectomy (VSG)] on transcriptome changes in the placenta . Female Adult, Long Evans were fed high fat diet (HFD, #D03082706, Research Diets) for 4 weeks, divided into sham-VSG or VSG groups, and following surgeries one group of sham-VSG and VSG were switched to normal diet (lean), while one sham-VSG group (obese) continued HFD. At gestdational day 18, placenta tissues harvested from pregnant female rats were processed for Affymetrix microarray and transcriptomic analysis performed.
