Description
Endometriosis is a benign gynecological condition that causes significant morbidity due to reduced fertility, pelvic pain and inflammatory dysfunctions. High-fat dietary intake has been linked to higher systemic inflammation and oxidative stress, which are both features of women with endometriosis. We evaluated the effects of high-fat diet (HFD) on endometriosis progression using immunocompetent mouse model wherein ectopic lesion was induced in wildtype and kruppel-like factor 9 (KLF9)- null donor mice. Results showed that HFD leads to increased ectopic lesion numbers and higher body weight gain. The HFD-promotion of lesion establishment was associated with decreased stromal estrogen receptor 1 and progesterone receptor expression, increased macrophage infiltration, and enhanced expression of pro-inflammarory and pro-oxidative stress pathway genes. Further, lesion-bearing mice had higher peritoneal fluid TNF- and elevated local/systemic redox status than control-fed mice.

Description
Maintenance and propagation of breast cancer stem cells (BCSCs) is mediated via cytokine and growth factor networks. Direct in vivo linkage between dietary regulation of mammary stem (MaSC)/progenitor cell numbers and protection from breast cancer has not been reported. Here, we investigated the effect of post-weaning intake of soy protein isolate (SPI) relative to the control casein (CAS) diet on the stem/progenitor population and tumor formation in MMTV-Wnt1-Transgenic (Wnt1-Tg) female mice. Gene expression profile of the basal (MaSC-enriched) sub-population in preneoplastic Wnt1-Tg mice demonstrated a stem cell-like expression pattern and markedly suppressed expression of inflammatory cytokines, C-X-C family chemokines, and metastasis-associated genes with dietary SPI exposure.

Description
Endometriosis is characterized by progesterone resistance and is associated with infertility. Krppel-like Factor 9 (KLF9) is a progesterone receptor (PGR)-interacting protein, and mice null for Klf9 are subfertile. Whether loss of KLF9 contributes to progesterone resistance of eutopic endometrium of women with endometriosis is unclear. The aim of this study was to investigate KLF9 and PGR co-regulation of human endometrial stromal cell (HESC) transcriptome network.

Description
Stem cell differentiation is known to involve changes in RNA expression, but little is known about translational control during differentiation. We comprehensively profiled gene expression during differentiation of embryonic stem cells (ESCs) into embyroid bodies (EBs) by integrating conventional transcriptome analysis with global assessment of ribosome loading. Differentiation was accompanied by an anabolic switch, characterized by global increases in transcript abundance, polysome content, protein synthesis rates and protein content. Furthermore, 78% of expressed transcripts showed increased ribosome loading, thereby enhancing translational efficiency. Elevated protein synthesis was accompanied by enhanced phosphorylation of eIF-4E binding protein, suggesting regulation by the mTOR pathway.

Description
Although human pluripotent stem cells-derived cardiomyocytes (hPSC-CMs) have emerged as a novel platform for heart regeneration, disease modeling, and drug screening, their immaturity significantly hinders their application. A hallmark of postnatal cardiomyocyte maturation is the metabolic substrate switch from glucose to fatty acids. We hypothesized that fatty acid supplementation would enhance hPSC-CM maturation. Fatty acid treatment induces cardiomyocyte hypertrophy and significantly increases cardiomyocyte force production. The improvement in force generation is accompanied by enhanced calcium transient peak height and kinetics, and by increased action potential upstroke velocity. Fatty acids enhance mitochondrial respiratory reserve capacity. RNA sequencing showed fatty acid treatment upregulates genes involved in fatty acid ß-oxidation and downregulates genes in lipid synthesis. Signal pathway analyses reveal that fatty acid treatment results in phosphorylation of multiple intracellular kinases. Thus, fatty acids increase human cardiomyocyte hypertrophy, force generation, calcium dynamics, action potential upstroke velocity, and oxidative capacity. This enhanced maturation should facilitate hPSC-CMs usage for cell therapy, disease modeling, and drug/toxicity screens. Overall design: We did RNA-seq of hPSC-CM culture in control and fatty acid media, with two biological replicates per condition

Description
Acute myeloid leukemia (AML) is associated with poor clinical outcome and the development of more effective therapies is urgently needed. G protein-coupled receptors (GPCRs) represent attractive therapeutic targets, accounting for approximately 30% of all targets of marketed drugs. Using next-generation sequencing, we studied the expression of 772 GPCRs in 148 genetically diverse AML specimens, normal blood and bone marrow cell populations as well as cord blood-derived CD34-positive cells. Among these receptors, 30 are overexpressed and 19 are downregulated in AML samples compared with normal CD34-positive cells. Upregulated GPCRs are enriched in chemokine (CCR1, CXCR4, CCR2, CX3CR1, CCR7 and CCRL2), adhesion (CD97, EMR1, EMR2 and GPR114) and purine (including P2RY2 and P2RY13) receptor subfamilies. The downregulated receptors include adhesion GPCRs, such as LPHN1, GPR125, GPR56, CELSR3 and GPR126, protease-activated receptors (F2R and F2RL1) and the Frizzled family receptors SMO and FZD6. Interestingly, specific deregulation was observed in genetically distinct subgroups of AML, thereby identifying different potential therapeutic targets in these frequent AML subgroups. Overall design: Total healthy bone marrow was sorted to isolate distinct cell populations. RNA-Seq analysis was performed on sorted cells to determine gene expression profile of healthy bona marrow subpopulations.

Description
Intestinal macrophages rely on the constant replenishment by bone marrow derived Ly6Chigh monocytes in the adult organism. The developmental path from monocytes towards intestinal macrophages locally in the tissue is defined by the loss of Ly6C and acquisition of MHCII and CX3CR1 expression. We used microarray analysis to further characterise this local differentiation process.
