Project description:In the current investigation, an RNA-seq analysis was conducted to examine the differentially expressed genes in old ADSCs (O-ADSCs) following the overexpression of HES1. The findings indicated that 448 genes exhibited increased levels, while 865 genes showed decreased levels in the oe-HES1 O-ADSCs compared to the oe-NC O-ADSCs. The GO analysis revealed that these genes are primarily localized in the nucleus and cytoplasm, and are involved in activities such as protein binding and DNA binding. Furthermore, they are associated with processes related to cell adhesion and the regulation of transcription by RNA polymerase II. The KEGG analysis indicated enrichment in pathways such as the NOD-like receptor signaling pathway, TNF signaling pathway, IL-17 signaling pathway, and PI3K-Akt signaling pathway.
Project description:To investigate target molecules of HES1, we transduced GFP or HES1 into mouse chondrocyte cell line ATDC5, and performed the microarray analysis. HES1 overexpression increased inflammation-related genes including Il6 and Il1rl1.

HES1 overexpression increased inflammation-related genes including Il6 and Il1rl1. We established stable ATDC5 cells overexpressing GFP or HES1 by lentiviral transduction. We harvested mRNA from these cells, and performed microarray analysis.

Project description:A human colon carcinoma-derived cell line LS174T was modified to overexpress Hes1, a bHLH-type transcription factor, upon doxycycline addition (designated as LS174T-tetON-Hes1 cells), using the T-rex system (Invitrogen). We have previously shown that these cells can overexpress Hes1 under the control of CMV promoter (Zheng et al, Inflamm Bowel Dis, 17;2251-2260, 2011), and the amont of the overexpressed Hes1 protein reaches to the maximal level in early as 3 hours from doxycycline addition (100ng/ml), which persists for up to 24 hours. In the present experiment, LS174T-tetON-Hes1 cells were treated with recombinant human IL-22 (20ng/ml) alone, doxycycline alone (100ng/ml), co-treated by both IL-22 and doxycycline, or left untreated (Control) for 24 hours, and subjected for analysis. Experiment was done using a modified sub-line of LS174T cell (LS174T-tetON-Hes1 cells), in which overexpression of Hes1 can be induced by a Doxycycline dependent manner. Four-condition experiment, Control vs. IL-22 stimulation, Control vs Doxycycline addition (Hes1 overexpression) and Control vs IL22 stimulation+Doxycycline addition (Hes1 overexpression). Biological replicates: One for each condition, independently grown and harvested. One replicate per array.
Project description:To investigate the effect of adipose tissue-specific overexpression of adrenomedullin 2 on the regulation of adipocyte function, the transgenic mouse line with adipocyte-specific overexpression of the ADM2 gene (aADM2-tg mice) was generated on a C57BL/6J background with the human ADM2 gene driven by the adiponectin (Adipoq) gene promoter (H11-Adipoq-hADM2-Wpre-PolyA mice, Strain NO. T059304). The mice were purchased from GemPharmatech (Nanjing, China). We then performed gene expression profiling analysis using data obtained from RNA-seg of visceral adipose tissue from aADM2-Tg and WT group.
Project description:The acidic microenvironment plays a key role to result in the poor survival and limited function of transplanted stem cells in ischemic diseases.In this study, different pH levels of medium were performed to treat adipose-derived stem cells (ADSCs) with 24/48h time- exposure, to explore the effect of extracellular acidosis on ADSCs.
