Project description:Through phenotypical study, we found that miR-205 can promote hair growth. The goals of this study is to identify direct targets of miR-205 in hair follicle stem cells and determine whether and how miR-205 promotes hair growth by activating hair follicle stem cell.

Project description:We identified 201 genes that are consistently upregulated more than 20%, and 108 genes that are consistently downregulated more than 20% in the miR-205 KO samples in two sets of biological duplicates. We used microarrays to measure transcriptome changes upon knockout of miR-205 in hair follicle stem cells of mouse skin and identified new targets of miR-205.

Project description:The study was aimed at identifying genes directly or indirectly regulated by miR-205 in the prostate. To this purpose, DU145 prostate cancer cells, which express miR-205 at very low levels, were transfected with miR-205 synthetic precursor and consequent alterations of gene expression analyzed using a microarray approach.

Project description:Micro RNAs (miRNAs) miR-130a, miR-203 and miR-205 are jointly downregulated in prostate cancer and act as repressors of AR-signaling. MiRNAs are small non-coding RNAs that regulate the expression of specific mRNA targets mainly by translational repression, mRNA deadenylation or cleavage. Reconstitution of these lost miRNAs in the LNCaP PCa cell line cause morphology changes, growth arrest, and apoptosis, increasing when the miRNAs were co-expressed. This series identifies direct targets of miR-130a, miR-203, and miR-205 by AGO2-RNA co-immunoprecipitation as described by (Beitzinger et al. 2007) upon miRNA reconstitution in LNCaP cells and analyzing AGO2-bound mRNAs using Affymetrix Genechips. Relative levels of AGO2 bound versus total RNA expression were compared between miRNA reconstituted and miR-scr transfected samples. Three arrays each for AGO2-bound RNA upon reconstitution of miR-130a, miR-203, miR-205, a scramble miRNA, and three arrays each for total RNA upon reconstitution of miR-130a, miR-203, miR-205, a scramble miRNA.

Bioinformatic target prediction, mRNA expression and protein expression analysis upon overexpression of these miRNAs congruently identified targets known to be overexpressed in PCa and to be involved in AR trans-activation. This series profiles loss in mRNA expression in LNCaP cells transfected with one of the three miRNAs miR-130a, miR-203 and miR-205 compared to LNCaP cells transfected with a scramble miRNA. We analyzed three arrays each for miR-130a, miR-203, miR-205, and a scramble miRNA.

Project description:In this study, the prognostic properties of miR-205 expression levels are investigated in a well-documented prostate cancer cohort. We show that miR-205 is correlated to shortened overall survival, significantly dividing the PCa patients into high and low risk groups. Furthermore, miR-205 is shown to inversely correlate to occurrence of metastases. In situ hybridization is also performed, demonstrating high miR-205 expression in the basal cells of benign prostate tissue glands. A RIP-Chip assay using an AGO2 antibody was implemented and the miR-205 targets identified were found to be enriched in MAPK/ERK, Toll-like receptor and IL-6 signaling pathways. We also found individual targets involved in cancer and androgen receptor signaling. Ectopic levels of miR-205 are shown to decrease the level of androgen receptor both at the mRNA and protein levels in prostate cancer cell lines. This is further corroborated in the prostate cancer cohort were miR-205 expression levels in the prostatic tissues are found to inversely correlate to assessment of androgen receptor (AR) immunostaining and to serum levels of PSA, a protein regulated by AR signaling. The level of miR-205 is also found to be significantly lower in castration resistant prostate cancer patients than in hormone naïve patients. Our data indicates that miR-205 is regulated by androgens and act by different mechanisms in androgen depleted settings, e.g. giving opposite effects on adhesion. Taken together these findings imply that miR-205 might have therapeutic potential especially for the castration resistant and currently untreatable form of prostate cancer.

Project description:Tears are essential for the maintenance of the terrestrial animal ocular surface and the lacrimal gland is the source of the aqueous layer of the tear film. Despite the importance of the lacrimal gland in ocular health, molecular aspects of its development remain poorly understood. We have identified a noncoding RNA (miR-205) as an essential gene for lacrimal gland development. Knockout mice lacking miR-205 fail to develop lacrimal glands, establishing this noncoding RNA as a key regulator of lacrimal bud initiation. RNA-seq analysis uncovered several up-regulated miR-205 targets, including Inppl1, a negative regulator of Akt signaling. Data indicate that Akt signaling is required within lacrimal gland epithelia and is activated by Fgf10. Furthermore, combinatorial epistatic deletion of Fgf10 and miR-205 in mice exacerbates the lacrimal gland phenotype. We develop a molecular rheostat model where miR-205 modulates signaling pathways downstream of Fgf10 to regulate glandular development. These data show that a single microRNA is a key regulator for lacrimal gland initiation in mice and highlights the important role of microRNAs during organogenesis.
