Description
Macrophage aging is pathogenic in numerous diseases, including age-related macular degeneration. Although prior studies have explored the functional consequences of macrophage aging, less is known about its cellular basis or what defines the transition from physiologic aging to disease. The purpose of this experiment was to characterize the transcriptomic changes associated with macrophage aging.

Description
The goal of this study was to determine what genes are up- and down-regulated in response to lupus immune complexes in purified CD14+ monocyte stimulations. Our results have shown that novel genes are induced by immune complexes but the response is less robust when using purified monocytes versus total PBMCs

Description
These experiments were done to compare the gene expression profiles in CD4+ T cells responding to antigen presented by dendritic cells transiently or persistently. Some treatments include the activation of the dendritic cells by CD40 engagement.
Publication Title
Sustained antigen presentation can promote an immunogenic T cell response, like dendritic cell activation.

Description
The aim of our study was to discover a miR marker panel prognostic of 5-year survival in OSCC patients that may be utilized in parallel with the current clinical covariates. We assessed differential expression of miRNAs genome-wide via deep sequencing in 20 tumor tissue samples. We also attempted to identify deregulated miR expression signatures that may serve as the prognostic marker of cancer survival. Selected miR marker-based panel then may serve as a guide for selection of appropriate follow-up chemo/radiation treatment, significantly improving the clinical management of OSCC and the overall survival rate. Overall design: Identify miRs differentially expressed in the poor prognosis group compared to the good prognosis group

Description
Ovariectomized virgin Ccnd1-/- and Ccnd1+/+ mice (5 weeks of age) were allowed to recuperate for 2 weeks. The mice were assigned to either replacement pellets containing E2 (0.75 mg, 60-day release) or pellet containing placebo. Mice were sacrificed at day 7 after pellet implantation. RNA extracted from mammary glands (3 each group) was labeled and used to probe Affymetrix 430_2.0 arrays.

Description
The CCND1 gene, which is frequently overexpressed in cancers, encodes the regulatory subunit of a holoenzyme that phosphorylates the retinoblastoma protein (pRb). It is known that cyclin D1 regulates ER transactivation using heterologous reporter systems, the significance of this observation to E2 dependent gene activation is unknow. E2 stimulated MCF7 cells treated with cyclin D1 siRNA in order to analyze the genes regulated by estradiol in a cyclin D1 dependent manner. Hormone deprived MCF7 cells were treated with cyclin D1 siRNA or control siRNA and stimulated with E2 or vehicle

Description
Previous studies have suggested that CD133+ cells isolated from human kidney biopsies have the potential to ameliorate injury following intravenous (IV) administration in rodent models of kidney disease by integrating into damaged renal tissue and generating specialised renal cells. However, whether renal engraftment of CD133+ cells is prerequisite for ameliorating injury has not yet been unequivocally resolved. Here, we have established a cisplatin-induced nephropathy model in immunodeficient rats to assess the efficacy of CD133+ human kidney cells in restoring renal health, and to determine the fate of these cells after systemic administration. Specifically, following IV administration, we evaluated the impact of the CD133+ cells on renal function by undertaking longitudinal measurements of the glomerular filtration rate using a novel transcutaneous device. Furthermore, using histological assays, we assessed whether the human kidney cells could promote renal regeneration, and if this was related to their ability to integrate into the damaged kidneys. Our results show that both CD133+ and CD133- cells improve renal function and promote renal regeneration to a similar degree. However, this was not associated with engraftment of the cells into the kidneys. Instead, after IV administration, both cell types were exclusively located in the lungs, and had disappeared by 24 hours. Our data therefore indicate that renal repair is not mediated by CD133+ cells homing to the kidneys and generating specialised renal cells. Instead, renal repair is likely to be mediated by paracrine or endocrine factors.

Description
Interplay between metabolic state of the cell and its ability to undergo immunological activation has been recently recognized as a treasure chest of novel fundamental regulatory principles. Itaconate, and its membrane permeable derivative dimethyl itaconate (DI) were recently shown to selectively inhibit subset of cytokines during macrophage activation (e.g. Il1b, il6, Il12b but not TNF), yet the precise mechanism of this effect remained unclear. We find that selectivity of DI action stems from the inhibitory effects of electrophilic stress exerted by DI on IkB-zeta protein translation, leading to selective control of the secondary wave of Nfkb-signaling. Mechanistically, DI leads to glutathione depletion and subsequent activation of both Nrf2-dependent and Nrf2-independent stress responses. We find that IkB-zeta regulation is carried out in Nrf2-independent manner, and identify Atf3 as a key mediator of DI effects on IkB-zeta/IL6. This inhibitory effect is conserved across species and cell types, as evident from inhibition of IkB-zeta production in activating human monocytes and IL-17A stimulated keratinocytes of both human and mice. Finally, DI administration in vivo ameliorated IL17/IkB-zeta-driven skin pathology in the mouse model of psoriasis, highlighting therapeutic potential of this regulatory pathway. Overall design: Bone marrow-derived macrophages (BMDMs) from WT and Nrf2–/– mice were derived in 7 days in MCSF supplemented complete RPMI. Some samples cells were stimulated with 250 uM DimethylItaconate(DI) for 12 hours prior to collection for RNA-seq.
