Description
Microglia constitutes a diverse population of cells that present a broad spectrum of responses when they become activated. Here, microglial status was studied under steady-state conditions from different brain regions involved in neurodegenerative diseases. Under basal conditions, midbrain microglia showed an immune-alert state not observed in striatum. Unique subpopulations of microglia expressing TLR4 and MHC-II with antigen presenting properties, and a higher proportion of infiltrating CD4+ T cells were identified in the midbrain. These results highlight that the inflammatory tone is context-dependent and reveal the unique properties of the midbrain related to the interaction with the immune system. Overall design: Analysis of two cohorts of control animals

Affymetrix Mouse Gene 2.1 ST Array (mogene21st)
Description
Adipose 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.

Description
In 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.

Description
The side population (SP), recently identified in several normal tissues and in a variety of tumors, may comprise cells endowed with stem cell features. In this study, we investigated the presence of SP in epithelial ovarian cancer (EOC) and found it in 4 out of 6 primary cultures from xenotransplants, as well as in 9 out of 25 clinical samples analyzed. SP cells from one xenograft bearing a large SP fraction were characterized in detail and they were capable of recreate the full repertoire of cancer cell populations observed in the parent tumor. Moreover, SP cells had higher proliferation rates, were much less apoptotic compared to non-SP cells, and generated tumors more rapidly than non-SP cells.

The side population of ovarian cancer cells is a primary target of IFN-alpha antitumor effects.

Description
We performed RNA sequencing analysis of hepatic gene expression a few hours after amlexanox treatment, and identified over 1700 differentially expressed genes. Pathway analysis of these differentially regulated genes revealed that the top two most enriched pathways were the adipocytokine signaling pathway and the Jak-STAT signaling pathway. Overall design: RNA-seq analysis of hepatic gene expression was used to identify differentially expressed genes in response to Amlexanox treatment.

Description
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.

Description
Eutopic 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.
