Project description:TCP1 papillary thyroid carcinoma cells were plated at 100,000 cells/well in a 6-well plate and transfected with 10nM of a synthetic pre-miR-129-5p or a negative pre-miRNA using Lipofectamine RNAiMAX reagent. RNA samples were harvested at 24 and 48 hours post-transfection.

Project description:In an RNAseq analysis, we have identified the microRNA hsa-miR-129-5p with high levels in acute wounds (day1 to day7) compared to normal skin. The biological function of this miRNA in human epidermal keratinocytes during wound repair has not been studied. To study the genes regulated by miR-129-5p , we transfected miR-mimics targeting miR-129-5p into human primary epidermal keratinocytes to over-express miR-129-5p expression. We performed a global transcriptome analysis of keratinocytes upon miRNA overexpression using Affymetrix arrays.

Project description:Amyotrophic lateral sclerosis (ALS) involves the degeneration of brain and spinal cord motor neurons. Mutations in Superoxide Dismutase 1 (SOD1), TAR DNA-binding protein 43 (TDP-43) and Fused-in-Sarcoma (FUS) account for 20-30 % of the familial ALS (fALS) cases. The RNA-binding proteins TDP-43 and FUS function in mRNA and miRNA biogenesis. MiRNAs are required for survival of neurons and deregulation of miRNA expression has been reported in several neurodegenerative disorders. Here, we report the dysregulation of DROSHA, DGCR8, and DICER in human neuroblastoma SH-SY5Y cells expressing the ALS-associated SOD1(G93A) mutant protein. MiRNA profiling in SH-SY5Y/SOD1(G93A) cells and transgenic SOD1(G93A) mice revealed upregulation of miR-129-5p at the early stage of disease. Moreover, miR-129-5p is also upregulated in lymphocytes of sporadic ALS patients. We demonstrate that miR-129-5p targets ELAVL4/HuD mRNA by binding to its 3’ UTR, which reduces HuD expression and impairs differentiation and neurite outgrowth. Conversely, treatment with an antagomir or complementation with HuD protein restores neuritogenesis. Collectively, our study identifies miR-129-5p and HuD as key regulators of neuronal differentiation and as potential therapeutic targets for ALS.

Project description:Background: Adrenal myelolipoma (AML) is a relatively common and invariably benign tumor composed of adipose tissue and hematopoietic elements. Due to the variable proportion of fat and hematopoietic elements, it is sometimes challenging to differentiate AML from adrenocortical carcinoma (ACC). MicroRNAs have been identified as promising biomarkers in many tumors, including adrenocortical neoplasms, but the microRNA expression of adrenal myelolipoma has not been investigated, yet. Aims: To perform a large scale microRNA expression profiling in adrenal myelolipoma, benign and malignant adrenocortical tumors to identify potential microRNA biomarkers. Methods: Next-generation sequencing (NGS) on 30 formalin-fixed paraffin-embedded archived tissue samples (discovery cohort: 10 adrenocortical adenoma (ACA), 10 ACC and 10 myelolipoma) was performed by Illumina MiSeq. Significantly differentially expressed microRNAs were validated by real-time RT-qPCR in an independent validation cohort comprised of 10 ACA, 10 myelolipoma and 9 ACC samples. Results: We have found relative overexpression of miR- 451a, miR-486-5p, miR-363-3p and miR-150-5p in myelolipoma compared to the other two tumor groups by NGS. For ACC, we have found up-regulation of miR-184, miR-483-5p, miR-431-5p and miR-183-5p compared to myelolipoma and ACA. Validation by RT-qPCR, confirmed significant overexpression of miR-451a, miR-486-5p and miR-150-5p in myelolipomas relative to ACA and ACC, whereas significant overexpression of miR-184 and miR-183-5p was confirmed in ACC relative to the other 2 groups. The overexpression of miR-483-5p has not turned out to be significant in ACC relative to myelolipomas in the validation cohort. Conclusions: Overexpressed miR-451a, miR-486-5p and miR-150-5p might be potential tissue markers of adrenal myelolipoma. The lack of significance in the expression of miR-483-5p between ACC and myelolipoma is remarkable, as miR-483-5p has been considered to be the best marker of adrenal malignancy to date.
