Illumina HiSeq 2500
Description
Our study demonstrated that e-cigarettes, both with and without nicotine, induced sex-dependent gene expression change. This RNA-seq study examined the expression profiles of brain frontal cortex samples from mice exposed to classic tobacco flavored bluâ„¢ e-cigarettes during gestation and lactation. Overall design: Brains were extracted and sectioned from ~1-month-old male and female offspring the week following exposure, RNA was isolated and purified from frontal cotrex tissues, and gene expression profiles were analyzed by RNA Sequencing.

- Affymetrix Rhesus Macaque Genome Array (rhesus)
Description
This study examined the small antral follicles (SAFs) in ovaries of young adult rhesus monkeys following consumption of a western-style diet (WSD), with or without chronically elevated androgen levels since before puberty. Cholesterol or testosterone (T; n=6/group) implants were placed subcutaneously beginning at 1 yr of age, with addition of a WSD (high fat/fructose) at 5.5 yrs. Ovaries from treated females and age-matched controls were collected at 7 yrs of age. Compared to controls, consumption of a WSD, with and without T treatment, increased the numbers of SAFs per ovary (P<0.001), due to the presence of more atretic follicles (P<0.01). Immunostaining for the cellular proliferation markers (pRb and pH3) was greater in granulosa cells of healthy SAFs (P<0.01), while staining for the cell cycle inhibitor (p21) was higher in atretic SAFs (P<0.01). Intense CYP17A1 staining was observed on the theca of SAFs from WSD+/- T groups, compared to controls. Microarray analyses of the transcriptome in SAFs isolated from a subgroup (n=3/grp) of WSD and WSD+T treated females and controls consuming a standard diet, identified mRNA levels for 1944 genes changed >2-fold (p<0.05) among the three groups. Pathway analyses identified several gene pathways altered by WSD and/or WSD+T associated with lipid, carbohydrate and lipid metabolism, plus ovarian processes. Alterations of several SAF mRNAs are similar to those observed in follicular cells from women with PCOS. These data indicate chronic exposure to a WSD in the presence and absence of chronically elevated T alters structure and function of SAFs within primate ovaries.

Description
We used RNA-seq as a method of next generation sequencing (NGS) to identify RIPK1 dependent inflammatory mediators and pathways in LPS injected mice. Overall design: Mice were divided intro 3 groups - control (n=2), LPS (n=2) and LPS/Nec-1 (n=2). BM cells were isolated by FACS as described for qPCR analysis. Total RNAs were isolated using Qiagen RNeasy kit according to the manufacturer's protocol

Description
HepG2 and THP-1 cells, the latter differentiated by phorbol 12-myristate 13-acetate (PMA), were co-cultured and characterized for typical liver-specific functions, such as xenobiotic detoxification, lipid and cholesterol metabolism. Furthermore, liver injury-associated pathways, such as inflammation, were studied. In general, the co-cultivation of these cells produced a pro-inflammatory system, as indicated by increased levels of cytokines (IL-8, TGF-α, IL-6, GM-CSF, G-CSF, TGF-β, and hFGF) in the respective supernatant. Increased expression levels of target genes of the aryl hydrocarbon receptor (AHR), e.g., CYP1A1, CYP1A2 and CYP1B1, were detected, accompanied by the increased enzyme activity of CYP1A1. Moreover, transcriptome analyses indicated a significant upregulation of cholesterol biosynthesis, which could be reduced to baseline levels by lovastatin. In contrast, total de novo lipid synthesis was reduced in co-cultured HepG2 cells. Key events of the adverse outcome pathway (AOP) for fibrosis were activated by the co-cultivation, however, no increase in the concentration of extracellular collagen was detected. This indicates, that AOP should be used with care. In summary, the indirect co-culture of HepG2/THP 1 cells results in an increased release of pro-inflammatory cytokines, an activation of the AHR pathway and an increased enzymatic CYP1A activity.

- Affymetrix Human Exon 1.0 ST Array [transcript (gene) version (huex10st)
Description
Klotho functions as an aging suppressor, which, in mice, extends lifespan when overexpressed and accelerates development of aging-like phenotypes when disrupted. Klotho is mainly expressed in brain and kidney and is secreted into the serum and CSF. We have previously shown that Klotho is reduced in brains of old monkeys, rats and mice. We further reported the ability of Klotho to enhance oligodendrocyte differentiation and myelination. Here we examined the effects of Klotho on MO3.13, a human oligodendroglioma cell line in order to determine the potential role of Klotho as a tumor suppressor. We show that exogenous Klotho affects the ERK and Akt signaling pathways and decreases the proliferative abilities of MO3.13 cells. Furthermore, microarray analysis of Klotho-treated MO3.13 cells reveals a massive change in gene expression with 80% of the differentially expressed genes being downregulated. Using gene set enrichment analysis we predicted potential transcription factors involved in regulating Klotho-treated MO3.13 cells and found that these cells are highly enriched in the gene sets, that are similarly observed in cancer, cardiovascular disease, stress, aging and hormone-related chemical and genetic perturbations. Since Klotho is downregulated in all brain tumors tested to date, enhancing Klotho has therapeutic potential for treating brain malignancies.
