PATZ1 is a transcriptional factor downregulated in thyroid cancer whose re-expression in thyroid cancer cells leads to a partial reversion of the malignant phenotype, including the capacity to proliferate, migrate, and undergo epithelial-to-mesenchymal transition. We have recently shown that PATZ1 is specifically downregulated downstream of the Ras oncogenic signaling through miR-29b, and that restoration of PATZ1 in Ha-Ras transformed FRTL5 rat thyroid cells is able to inhibit their capacities to proliferate and migrate in vitro...

Oxygen-glucose deprivation (OGD)-activated microglia contribute to neuronal apoptosis via releasing pro-inflammatory cytokines, and some miRNAs have been reported to be involved in this process. Circular RNAs (circRNAs) have been reported to function as miRNA sponges, but it remains unknown whether and how circRNAs contribute to OGD-activated microglia-induced neuronal apoptosis. Here, we investigated the function and relationship of miR-29b and circPTK2 in OGD-activated microglia-induced neuronal apoptosis...

Insulin resistance is the major pathological characteristic of type 2 diabetes and the elderly often develop insulin resistance. However, the deep-seated mechanisms for aging-related insulin resistance remain unclear. Here, we showed that nano-sized exosomes released by bone marrow mesenchymal stem cells (BM-MSCs) of aged mice could be taken up by adipocytes, myocytes, and hepatocytes, resulting in insulin resistance both in vivo and in vitro. Using microRNA (miRNA) array assays, we found that the amount of miR-29b-3p was dramatically increased in exosomes released by BM-MSCs of aged mice...

BACKGROUND: MicroRNAs (miRs) regulate many biological processes, such as invasion, angiogenesis, and metastasis. Glioblastoma (GBM) patients with metastasis/metastatic dissemination have a very poor prognosis; therefore, inhibiting metastasis/metastatic dissemination has become an important therapeutic strategy for GBM treatment. METHODS: Using 76 GBM tissues, we examined the expression levels of 23 GBM-related miRs and compared the miRs' expression levels between GBMs with metastasis/metastatic dissemination and GBMs without metastasis/metastatic dissemination...

Inhibiting aberrantly upregulated microRNAs (miR/miRNAs) has emerged as a novel focus for therapeutic intervention in human melanoma. Thus, identifying upregulated miRNAs is essential for identifying additional melanoma-associated therapeutic targets. In the present study, microarray-based miRNA profiling of canine malignant melanoma (CMM) tissue obtained from the oral cavity was performed and differential expression was confirmed by a reverse transcription-quantitative polymerase chain reaction (RT-qPCR). An analysis of the microarray data revealed 17 dysregulated miRNAs; 5 were upregulated and 12 were downregulated...

OBJECTIVES: Cholangiocarcinoma (CCA) represents the second most common primary hepatic malignancy. Despite tremendous research activities, the prognosis for the majority of patients is still poor. Only in case of early diagnosis, liver resection might potentially lead to long-term survival. However, it is still unclear which patients benefit most from extensive liver surgery, highlighting the need for new diagnostic and prognostic stratification strategies. METHODS: Serum concentrations of a 4 miRNA panel (miR-122, miR-192, miR-29b and miR-155) were analyzed using semi-quantitative reverse-transcriptase PCR in serum samples from 94 patients with cholangiocarcinoma undergoing tumour resection and 40 healthy controls...

OBJECTIVE: Chondrocyte hypertrophy, a terminal stage of chondrocyte differentiation, is essential to the endochondral bone formation and is one of the major pathological factors in osteoarthritis. This study investigated the role of microRNA-29b (miR-29b), which is involved in chondrogenesis, in the regulation of hypertrophy in chondrocytes. METHODS: miR-29b expression was assessed during murine mesenchymal stem cells (mMSCs) chondrogenesis. To detect whether miR-29b affects chondrocyte hypertrophy, the mMSCs induced toward chondrogenesis were transfected with miR-29b or its antisense inhibitor (antagomiR-29b)...

Hematopoietic stem cell transplantation is commonly used in patients with certain hematological or bone marrow tumors. Total body irradiation combined with chemotherapy is part of the preconditioning protocol that was the most commonly used before hematopoietic stem cell transplantation. However, total body irradiation preconditioning damages other normal cells in bone marrow. Therefore, exploring the mechanism of radiation resistance in bone marrow mesenchymal stem cells is of great significance for recovering the hematopoietic function after cell transplantation...

Osteogenic differentiation of human bone marrow-derived mesenchymal stem cells (hBMSCs) is quite important for the bone formation. Bone morphogenetic proteins (BMPs) are important to the skeleton formation. As a member of BMPs, BMP1 can induce bone and cartilage development. This study revealed the biological effect of BMP1 on the osteogenic differentiation. Firstly, the relative lower expression of BMP1 was detected in hBMSCs obtained from osteoporosis patients. The expression levels of osteoporosis-related genes (ALP, OCN, and OPN) were found to be decreased in hBMSCs treated with sh-BMP1...

MicroRNAs (miRNAs) are small RNA molecules that inhibit gene function by suppressing translation of target genes. However, in primary central nervous system lymphoma (PCNSL), the biological significance of miRNAs is largely unknown, although some miRNAs are known to be prognosis markers. Here, we analyzed 847 miRNAs expressed in 27 PCNSL specimens using microarray profiling and surveyed miRNA signature for prognostic prediction. Of these, 16 miRNAs were expressed in 27 PCNSL specimens at a frequency of 48%...

Pancreatic cancer is one of the leading causes of solid carcinoma with the worst survival rate. The reasons for the worst survival rate include the lack of biomarkers for early detection, diagnosis at a late stage, and the limitation of the current therapy. Further study to investigate the underlying molecular mechanism in pancreatic cancer patients is necessary. A previous study showed that the miR-29b expression level is dysregulated, suggesting that it may serve an important function in pancreatic cancer...

Evidence has shown that microRNAs (miRNAs) are involved in molecular pathways responsible for aging and prevalent aging-related chronic diseases. However, the lack of research linking circulating levels of miRNAs to changes in the aging brain hampers clinical translation. Here, we have investigated if serum expression of brain-enriched miRNAs that have been proposed as potential biomarkers in Alzheimer's disease (AD) (miR-9, miR-29b, miR-34a, miR-125b, and miR-146a) are also associated with cognitive functioning and changes of the cerebral cortex in normal elderly subjects...

MicroRNAs participate in the regulation of abnormal cardiomyocyte apoptosis and autophagy, which leads to heart failure (HF). Lower miR-29b-3p levels were found in HF patients in this study. However, the role of miR-29b-3p in the molecular pathogenesis of HF remains unclear. Hypoxia-stimulated H9c2 cells were used an in vitro model of HF. It was found that hypoxia stimulation decreased the miR-29b-3p expression and enhanced cell apoptosis and autophagy response in H9c2 cells. While the effects of hypoxia on cell apoptosis and autophagy were reversed by miR-29b-3p transfection, especially 100 nM...

Hepatocellular carcinoma (HCC) is one of the most common malignant tumors worldwide, and current treatments exhibit limited efficacy against advanced HCC. The majority of cancer-related deaths are caused by metastasis from the primary tumor, which indicates the importance of identifying clinical biomarkers for predicting metastasis and indicating prognosis. Patient-derived cells (PDCs) may be effective models for biomarker identification. In the present study, a wound healing assay was used to obtain 10 fast-migrated and 10 slow-migrated PDC cultures from 36 HCC samples...
