Description
The first HSCs are produced in the aorta-gonadmesonephros (AGM) region of the embryo through endothelial to a hematopoietic transition. BMP4 and Hedgehog affect their production/expansion, but it is unknown whether they act to affect the same HSCs. In this study using the BRE GFP reporter mouse strain that identifies BMP/Smad-activated cells, we find that the AGM harbors two types of adult-repopulating HSCs upon explant culture. Overall design: Embryonic day 11 AGM are dissected and either analyzed directly, or after explant culture in conditions containing BMP/Hedgehog with or without cyclopamine. EC: endothelial enriched (CD31+Kit-); MC: mesenchymal cell enriched (CD31-Kit-); HPSC: hematopoietic progenitor/stem cell enriched; AGM11: E11 fresh AGMs; AGMex: AGM after explant culture; AGMcy: AGM after explant in presence of cyclopamine; CD31p: CD31 positive; CD31n: CD31 negative; KITp: c-Kit positive; KITn: c-Kit negative; BREp: BRE-GFP positive; BREn: BRE-GFP negative

Description
NMuMG is an epithelial cell line that can be induced into EMT by TGF- treatment or MET by TGF- withdrawl. During EMT, several marker genes were downregulated/upregulated, which is consistent with its mesenchymal phenotype.

Description
PKA activation by FSH is essential to transduce FSH-mediated effects on granulosa cell proliferation, differentiation and steroidogenesis. However, It is unknown whether activation of PKA is sufficient to account for the entire program of granulosa cell responses to FSH. We addressed this question by conducting a comprehensive comparative analysis of signaling pathways and gene expression profiles of granulosa cells stimulated with FSH or expressing a constitutively active PKA mutant, PKA-CQR.

Description
The goal of this project was to assess differential gene expression in the Ventral Nerve Cord (VNC) of adult Drosophila 5 hours after severing of the legs, wings and head. Overall design: Gene expression was assessed in 2 conditions (No Injury and 5-hrs after Injury) in the w1118 strain of Drosophila melanogaster. 5 independent biological replicates were used for each condition. RNA was isolated from the adult Ventral Nerve Cord (VNC) for the gene expression analysis (RNAseq).

Obesity is a risk factor for numerous metabolic disorders; however, not all obese individuals are prone to insulin resistance. The central aim of this study was to identify molecular pathways directly related to insulin resistance independent of BMI in obesity.

Description
Whole genome microarrays were probed with total mRNA from PTD-DRBD GAPDH siRNA treated H1299 cells at 12 h and 24 h. Using a 1.6x fold increase/decrease filter of cellular mRNAs, we detected a dramatic reduction in the target GAPDH mRNA along with a limited number of both up and down regulated genes. The up regulated genes were reduced in numbers and to nearly background 1.6x levels at 24 h, while the down regulated genes increased slightly in numbers and maintained a similar magnitude at 24 h. In contrast, lipofection treated cells showed both a dramatic increase in both the total number of genes altered and the magnitude of the increase. In addition, the numbers of genes affected increased between 12 h and 24 h, suggesting that lipofection of siRNAs into cells results in a substantial alteration to the transcriptome and may thereby confound interpretation of experimental outcomes. Moreover, the GAPDH specific knockdown was significantly smaller than PTD-DRBD mediated knockdown.

Description
Purpose: Black/African American (AA) women are twice as likely to be diagnosed with triple negative breast cancer (TNBC) compared to whites, an aggressive breast cancer subtype associated with poor prognosis. There are no routinely used targeted clinical therapies for TNBC; thus there is a clear need to identify prognostic markers and potential therapeutic targets. Methods: We evaluated expression of 27,016 genes in 155 treatment-naïve TN tumors from AA women in Detroit. Associations with survival were evaluated using Cox proportional hazards models adjusting for stage and age at diagnosis, and p-values were corrected using a false discovery rate. Our validation sample consisted of 158 TN tumors (54 AA) from The Cancer Genome Atlas (TCGA). Meta-analyses were performed to obtain summary estimates by combining TCGA and Detroit AA cohort results. Results: In the Detroit AA cohort, CLCA2 [Hazard ratio (HR)=1.56, 95% confidence interval (CI) 1.31-1.86, nominal p=5.1x10-7, FDR p=0.014], SPIC [HR=1.47, 95%CI 1.26-1.73, nominal p=1.8x10-6, FDR p=0.022], and MIR4311 [HR=1.57, 95% CI 1.31-1.92, nominal p=2.5x10-5, FDR p=0.022] expression were associated with overall survival. Further adjustment for treatment and breast cancer specific survival analysis did not substantially alter effect estimates. Meta-analysis with TCGA data showed that CLCA2 and SPIC were associated with overall survival for TNBC among AA women. Conclusions: We identified three potential prognostic markers for TNBC in AA women, for which SPIC may be an AA-specific prognostic marker.

Description
We confirmed immune response as the key mechanism and provided solid evidence for novel genes (e.g., FCAR and CUX1) and distinct biological processes (e.g., endocytosis, cytokine production and apoptosis) as potentially new important factors/mechanisms contributing to chronic periodontitis pathogenesis. Overall design: We performed an RNA-sequencing (RNA-seq) study of peripheral blood monocytes (PBMs) in 5 non-smoking moderate to severe CP (case) subjects vs. 5 controls. We replicated the DEx transcripts/isoforms using an independent microarray dataset. We also pathway-based analysis on the identified/replicated DEx transcripts/isoforms using DAVID performed (Database for Annotation, Visualization and Integrated Discovery).
