Project description:To investigate the competing endogenous RNA expression changes in decidua under the inflammatory reaction, LPS (100 μg/kg body weight) was intraperitoneally injected into the mice at 15 days of pregnancy. Premature births has been found after approximately 48 h of treatment. When bleeding found in vagina, the decidua were selected in asepsis condition, and total RNA was isolated to analyze the expression of competing endogenous RNA compared with cesarean sections.
Project description:To build up competing endogenous RNA regulatory network based on APP/PS1 transgenic mice model and verify Rpph1, miR-330-5p and Cdc42 interaction
Project description:We used microarray to detail Competing endogenous RNA expreession in placenta tissues from normal human and patients with severe preeclampsia
Project description:LncRNA for anti-oxidative capacity control has not been discovered yet. Nrf2 is a central molecule for cellular defense by increasing anti-oxidative capacity. Here, we identified a novel lncRNA named ‘NACER’ (Nrf2 Activating Competing Endogenous RNA) transcribed from an upstream region of MIR122. NACER existed in the cytoplasm, suggestive of its function as competing endogenous RNA (ceRNA, miRNA sponge). NACER served as ceRNA for Plk2 and p21cip1 through binding for miR-128/224, inducing Plk2/Nrf2/p21cip1 complexation for Nrf2 activation in cells under p53-activating conditions (i.e., DNA damage and serum deprivation). NACER expression was suppressed when apoptosis was initiated, being a rheostat for cell fate determination. NACER levels correlated with the recurrence free survival rate of patients with hepatocellular carcinoma after surgery. Collectively, NACER promotes Plk2 and p21cip1 translation by competing for specific miRNAs, activating Nrf2 under the surviving condition from oxidative stress, implying that NACER plays a fine-tuning rheostat for cell fate decision.
Project description:To identify differentially expressed transcripts (long-noncoding RNAs [lncRNAs], microRNAs [miRNAs], and mRNAs) and competing endogenous RNA (ceRNA) networks closely connected with endometrial receptivity, we analyzed gene expression profiles between the proliferative and mid-secretory endometria in fertile women.
Project description:SLE is a disease characterised by immune inflammation and damage to multiple organs. Recent investigations have linked competing endogenous RNAs (ceRNAs) to lupus. However, the exact mechanism through which the ceRNAs network affects SLE is still unclear. This study aims to investigate the regulatory functions of the ceRNAs network, which are important pathways that control the pathophysiological processes of SLE. We constructed a novel circRNA-miRNA-mRNA ceRNA network (HSA circ 0000345- HSA miR-22-3-P-ESR1/SIRT1) that may have a major impact on SLE.
