MicroRNA-22 upregulation by vitamin D mediates its protective action against colon cancer.

Project description:Vitamin D deficiency is associated with high risk of colon cancer and a variety of other diseases. The active vitamin D metabolite 1,25-dihydroxyvitamin D3 (1,25(OH)2D3) regulates gene transcription via its nuclear receptor (VDR), and posttranscriptional regulatory mechanisms of gene expression have also been proposed. We have identified microRNA-22 (miR-22) and several other miRNA species as 1,25(OH)2D3 targets in human colon cancer cells. Remarkably, miR-22 is induced by 1,25(OH)2D3 in a time-, dose-, and VDR-dependent manner. In SW480-ADH and HCT116 cells, miR-22 loss-of-function by transfection of a miR-22 inhibitor (anti-miR-22) suppresses the effect of 1,25(OH)2D3. Additionally, miR-22 inhibition increases cell migration per se and decreases the antimigratory effect of 1,25(OH)2D3 in both cell types. In silico analysis shows a significant overlap between genes suppressed by 1,25(OH)2D3 and miR-22 putative target genes. Consistently, miR-22 inhibition abrogates the reduction by 1,25(OH)2D3–mediated suppression of NELL2, OGN, HNRPH1, and NFAT5 genes. In 39 out of 50 (78%) human colon cancer patients, miR-22 expression was found lower in the tumor than in the matched normal tissue and correlated directly with that of VDR. Our results indicate that miR-22 is induced by 1,25(OH)2D3 in human colon cancer cells and it may contribute to its antitumor action against this neoplasia. We have analysed a human colon cancer cell line, SW480-ADH, treated with 1,25(OH)2D3 or isopropanol (vehicle) at three different time points (24, 48 and 96 hours). Each experiment was replicated 2 times by dye swap.

Microarray analysis of gene expression of ovarian cancer cells treated with 1,25-dihydroxyvitamin D3

Project description:To profile the changes in the pattern of gene expression in human OCa cells induced by 1,25(OH)2D3, OVCAR3 cells were treated with 0.1 pM 1,25(OH)2D3 for 0, 8, 24 and 72 h. The cells were harvested, RNA was extracted, and Affmetrix microarrays were hybridized. OVCAR3 cells were treated with 0.1 pM 1,25(OH)2D3 for 0, 8, 24 and 72 hours. 1,25(OH)2D3 was added at different times to allow the treated cells to be harvested at the same time. Ethanol was included as vehicle controls and all cells were exposed to the same amount of ethanol for the same length of time. Total RNA was extracted using Trizol reagent (Invitrogen) and purified using Qiagen Rneasy kit as recommended by Affymetrix. In the initial set of array analysis with U95 chips, GADD45 was identified to be a VD-induced gene in OVCAR3 cells, which was confirmed by a follow-up study to be a primary target gene. For the array analyses with U133A chips, the response to 1,25(OH)2D3 of the cells used for RNA isolation was ensured by Northern blotting analysis of GADD45. Three independent experiments were performed.

Vitamin D receptor (VDR) target genes in THP-1 monocytic leucemia cells

Project description:The biologically active form of vitamin D, 1,25-dihydroxyvitamin D3 (1,25(OH)2D3), is a direct regulator of gene transcription, since it is the only high affinity natural ligand of the transcription factor vitamin D receptor (VDR). Transcriptome-wide analysis of THP-1 human monocyte-like cells had indicated more than 600 genes to be significantly (p < 0.05) regulated after a 4 h stimulation with 1,25(OH)2D3. In this study, we screened of the list of primary vitamin D targets for genes encoding for transcriptional regulators and selected those of the activating transcription factor NFE2 and the transcriptional repressor BCL6. Both genes are under the control of two VDR loci and are the only 1,25(OH)2D3 targets within their respective chromosomal domain. However, NFE2 mRNA was rapidly up-regulated, while the increase of BCL6 expression showed a slower rise. After 24 h incubation of THP-1 cells with 1,25(OH)2D3 more than 1,500 genes responded significantly (p < 0.001), of which 132 where more than 2-fold induced. Public chromatin immunoprecipitation-sequencing datasets suggested that the majority of these genes could be targets of NFE2 or BCL6. In time course experiments we displayed for representative gene examples the specific delayed response of secondary 1,25(OH)2D3 targets and confirmed for the respective chromosomal domains the genomic binding of NFE2, BCL6 and VDR. In conclusion, our study indicated that the physiological response of monocytes to 1,25(OH)2D3 involves the action of NFE2 and BCL6. THP-1 cells were treated 24 h either with 0.1% ethanol (vehicle, control) or 1?,25(OH)2D3 (1,25D)
