A growing number of long non-coding RNAs (lncRNAs) have been found to be involved in diverse biological processes such as cell cycle regulation, embryonic development, and cell differentiation. However, limited knowledge is available concerning the underlying mechanisms of lncRNA functions. In this study, we found down-regulation of TCONS_00041960 during adipogenic and osteogenic differentiation of glucocorticoid-treated bone marrow mesenchymal stem cells (BMSCs). Furthermore, up-regulation of TCONS_00041960 promoted expression of osteogenic genes Runx2, osterix, and osteocalcin, and anti-adipogenic gene glucocorticoid-induced leucine zipper (GILZ)...

Pulmonary arterial hypertension (PAH) is a progressive vascular remodeling disease characterized by a persistent elevation of pulmonary artery pressure, leading to right heart failure and premature death. Exaggerated proliferation and resistance to apoptosis of pulmonary artery smooth muscle cells (PASMCs) is a key component of vascular remodeling. Despite major advances in the field, current therapies for PAH remain poorly effective in reversing the disease or significantly improving long-term survival. Because the transcription factor FOXM1 is necessary for PASMC proliferation during lung morphogenesis and its overexpression stimulates proliferation and evasion of apoptosis in cancer cells, we thus hypothesized that upregulation of FOXM1 in PAH-PASMCs promotes cell expansion and vascular remodeling...

Embryonic implantation in sows is a coordinated interaction between the implantation-competent blastocyst and receptive uterus. In addition, microRNAs are small endogenous non-coding RNAs which are involved in post-transcriptional gene regulation of several biological processes including embryonic implantation. However, the mechanisms of miRNAs involved in embryonic implantation of sows remain largely unknown. Here, we analyzed miRNAome of endometrium on day 9, 12 and 15 of pregnancy and on day 12 of non-pregnancy in Meishan and Yorkshire pigs by Illumina sequencing...

Optic nerve injury is a common disease. The present study aimed to examine the possible role of microRNA‑204 (miR‑204) in optic nerve injury through the regulation of growth‑associated protein-43 (GAP‑43). Initially, optic nerve injury models were established in Sprague‑Dawley (SD) rats, and the function of miR‑204 was either enhanced or inhibited through injection of miR‑204 mimic and inhibitor, respectively. Subsequently, the mRNA and protein levels of miR‑204, GAP‑43, toll‑like receptor 4 (TLR4), myeloid differentiation factor 88 (MyD88) and nuclear factor‑κB (NF‑κB) were examined in retinal tissues using reverse transcription‑quantitative polymerase chain reaction and western blot analyses...

Gastric cancer (GC) is the second most frequent cause of cancer-related deaths worldwide. MicroRNAs are single-stranded RNA molecules of 21-23 nucleotides that regulate target gene expression through specific base-pairing interactions between miRNA and untranslated regions of targeted mRNAs. In this study, we generated a multistep approach for the integrated analysis of miRNA and mRNA expression. First, both miRNA and mRNA expression profiling datasets in gastric cancer from the Gene Expression Omnibus (GEO) and The Cancer Genome Atlas (TCGA) identified 79 and 1042 differentially expressed miRNAs and mRNAs, respectively, in gastric cancer...

MicroRNAs (miRNAs) have been implicated in a wide range of biological processes including angiogenesis. MiR-204 was identified as a tumor suppressor in multiple cancer types, including lung adenocarcinoma. However, the function of miR-204 in lung tumor angiogenesis remains unknown. In this study, we found that the miR-204 expression was decreased in lung adenocarcinoma based on the cancer genome atlas (TCGA) analysis and gain-of-function experiment showed that miR-204 promoted cancer cell apoptosis and suppressed cell proliferation, migration in vitro and tumor growth in vivo...

BACKGROUND/AIMS: Hypoxic/ischemic injury to the liver is a frequently encountered clinical problem with limited therapeutic options. Since microRNAs (miRNAs) are involved in hypoxic/ ischemic events, and δ-opioid receptor (DOR) is protective against hypoxic/ischemic injury, we asked if pharmacological activation of DOR can alter hypoxic events by regulating miRNA expression in the liver. As the first step, the present work aimed at testing the effect of DOR activation on hepatic miRNA expression in hypoxia...

MicroRNA-204 (miR-204) is highly expressed in cornea, here we explored the role and mechanism of miR-204 in corneal neovascularization (CNV). Mouse CNV was induced by intrastromal placement of suture in BALB/c mice with the subconjunctival injection of miR-204 agomir or negative control. Human primary limbal epithelial cells (LECs) and immortalized microvascular endothelial cells (HMECs) were used to evaluate the expression changes and anti-angiogenic effects of miR-204 under biomechanical stress (BS). The expression and localization of miR-204, vascular endothelial growth factor (VEGF) and their receptors were detected by quantitative real-time PCR, in situ hybridization, immunohistochemistry and Western blot...

Melanoma treatment with the BRAF V600E inhibitor vemurafenib (VMF) provides therapeutic benefits but the common emergence of drug resistance remains a challenge. We generated A375 melanoma cells resistant to VMF with the goal of investigating changes in miRNA expression patterns that might contribute to resistance. Increased expression of miR-204-5p and miR-211-5p occurring in VMF-resistant cells was determined to impact VMF response. Their expression was rapidly affected by VMF treatment through RNA stabilization...

Chemotherapy is important for adjuvant treatment of prostate cancer. However, some cancer cells exhibited low sensitivity to chemotherapeutic agents. We are supposed to sensitize these prostate cancer cells to chemotherapeutic agents such as doxorubicin. Previous reports have suggested that microRNAs (miRNAs) regulate chemosensitivity in various cancers. In the present study, we observed that expression level of miR-204 was decreased in prostate cancer cell lines and patients' tumors. Furthermore, we found that restore of miR-204 dramatically enhanced the cytotoxicity of doxorubicin (DOX) against prostate cancer cell lines C4-2 and LNCaP carrying wild type (WT) p53...

Ovarian cancer (OC) is one of the most fatal gynecological cancer in women worldwide. Long noncoding RNA (lncRNA) lncBRM was found to be associated with the progression and prognosis of hepatocellular carcinoma (HCC). However, the expression level, clinical significance and functions in OC tumorigenesis and progression remain unclear. Our present research demonstrated that lncBRM expression was significantly increased in OC tissues. Upregulation of lncBRM expression was correlated with histological grade, FIGO stages, lymph node metastasis and poor prognosis of patients with OC...

Hematopoietic stem cell (HSC) transplantation could be of therapeutic value for aplastic anemia (AA) patients, and immunosuppressants may facilitate the efficiency of the procedure. As anti-inflammatory cytokine interleukin-11 (IL-11) has a thrombopoietic effect, its use in cases of chronic bone marrow failure, such as AA, has been proposed to induce HSC function. However, the putative mechanisms that may support this process remain poorly defined. We found that decreased miR-204-5p levels were coincident with increased proliferation in mouse HSCs following exposure to IL-11 in vitro...

Osteoarthritis (OA) is a common degenerative disease characterized by degeneration of articular cartilage. Increasing studies showed that long noncoding RNAs (lncRNAs) play important roles in the cartilage damage. However, little is known about the role of UCA1 in the osteoarthritis. The expression level of UCA1 was upregulated in the OA cartilage. Overexpression of UCA1 suppressed the miR-204-5p expression in the chondrocytes. The expression of miR-204-5p was downregulated in the OA cartilage. Moreover, the expression of miR-204-5p was negatively correlated with the UCA1 expression in the OA cartilage...

MiR-204 and 211 enforced expression in murine mesenchymal stromal cells (MSCs) has been shown to induce adipogenesis and impair osteogenesis, through RUNX2 down-modulation. This mechanism has been suggested to play a role in osteoporosis associated with obesity. However, two further fundamental MSC functions, chondrogenesis and hematopoietic supporting activity, have not yet been explored. To this end, we transduced, by a lenti-viral vector, miR-204 and 211 in a model primary human MSC line, opportunely chosen among our MSC collection for displaying all properties of canonical bone marrow MSCs, except adipogenesis...

Pulmonary arterial hypertension (PAH) is a devastating disease characterized by high pulmonary artery pressure. It is reported that microRNA-204 (miR-204) plays an important role in the development of PAH. Calcitriol [1,25-dihydroxyvitamin D3, 1,25(OH)2D3] mediates multiple pathophysiological processes. The aim of the current study was to explore the role of 1,25(OH)2D3 in PAH. PAH was induced in rats and rat pulmonary arterial endothelial cells (PAECs) were isolated as in vitro PAH model. The mean pulmonary artery pressure, morphologic changes, and expressions of transforming growth factor-beta1 (Tgfbr2), Smad2/7, alpha smooth muscle actin (α-SMA), and p21 were then measured...

Experimental and clinical evidence have demonstrated aberrant expression of cytokines/chemokines and their receptors in patients with hippocampal sclerosis (HS) and focal cortical dysplasia (FCD). However, there is limited information regarding the modulation of cytokine/chemokine-regulatory networks, suggesting contribution of miRNAs and downstream transcription factors/receptors in these pathologies. Hence, we studied the levels of multiple inflammatory mediators (IL1β, IL1Ra, IL6, IL10, CCL3, CCL4, TNFα and VEGF) along with transcriptional changes of nine related miRNAs and mRNA levels of downstream effectors of significantly altered cytokines/chemokines in brain tissues obtained from patients with HS (n = 26) and FCD (n = 26)...
