Human exosomal placenta-specific miRNAs modulate expression of target genes in maternal immune cells during pregnancy

ABSTRACT: We investigated placenta-specific miRNA miR-517a (miR-517a-3p) functions in Jurkat cells. For this purpose, we identified candidate target mRNAs of the placenta-specific miRNAs using DNA microarray analysis. Transfection of Jurkat cells with miR-517a significantly downregulated 123 genes. Among the 123 genes identified, we searched for potential direct targets of miR-517a using the online software MicroCosm Targets. Seven genes, ALDH1B1, ANP32E, DHFR, FAT2, IGSF5, PRKG1, and RSPO3, had at least one potential miR-517a binding site in their 3’-UTRs. Furthermore, we revealed that PRKG1, one of the seven genes, was a miR-517a target using an in vitro experimental validation system.

Furthermore, we revealed that PRKG1, one of the seven genes, was a miR-517a target using an in vitro experimental validation system. We compared gene expression pattern of miR-517aM-bM-^@M-^Soverexpressing Jurkat cells with that of negative control.

Identification of target genes of tumor suppressor microRNAs in human cancer

Project description:To identify target genes of tumor suppressive microRNAs in human cancer, several cell lines (bladder cancer, prostate cancer, renal cell carcinoma, and head and neck squamous cell carcinoma) were subjected to Agilent whole genome microarrays. miR-517a, miR-218, miR-145, miR-1 and miR-874 function as tumor suppressors. Human cancer cell lines (BOY, T24, A498, PC3, DU145, FaDu, SAS, HSC3, IMC3) were transfected with miRNAs (miR-517a, miR-218, miR-145, miR-1, miR-874). The miRNA-transfected human cancer cell lines were compared to control cell lines.

mRNA expression profile modified by microRNA mir-517a (MIR517A) in human hepatocellular carcinoma cell line

Project description:mRNA expression profile modified by stable transfection of microRNA mir-517a (MIR517A) in a human hepatocellular carcinoma cell line Huh-7 Keywords: Hepatocellular carcinoma, Expression array, microRNA microRNA mir-517a (MIR517A) was transfected to Huh-7 cells using GFP-expressing lentiviral vector. Infected cells were selected using flow cytometry and subjected to mRNA expression microarray experiment. The profiles were compared to controls cells infected with only GFP protein.

microRNA sequencing of human placentae and matched maternal plasma from 6-23 weeks of gestation

Project description:microRNAs are increasingly seen as important regulators of placental development and opportunistic biomarker targets. We generated miRNA profiles using 96 placentas from presumed normal pregnancies, across early gestation, in combination with matched profiles from maternal plasma. We identified 637 miRNAs with expression in 86 samples (after removing poor quality samples), showing a clear gestational age gradient and identified 374 differentially expressed (DE) miRNAs across a gestational cut-off of 6-10 weeks’ and 11-23 weeks’. We see a clear gestational age group bias in miRNA clusters C19MC, C14MC, miR-17~92 and paralogs, regions that also include many DE miRNAs. Proportional change in expression of placenta-specific miRNA clusters was reflected in maternal plasma, with C19MC miRNAs miR-516b-5p and 517a-3p showing potential as a biomarkers. Chorionic villous samples across early gestation display differential miRNA profiles, particularly in the expression of highly placenta-specific miRNA clusters, and at the presumed introduction of oxygenated maternal blood into the placenta. Data presented here comprise a clinically important reference set for studying early placenta development and enabling development of minimally invasive methods for monitoring placental health.

role of miR-146a on Jurkat T cells

Project description:screenning the differentially expressed genes of Jurkat-FF3, Jurkat-miR146a, Jurkat-miR146a-sponge cell lines. To investigate the role of miR-146a on Jurkat T cells, we screened the differentially expressed genes of Jurkat-FF3 (as control), Jurkat-miR146a (as miR-146a overexpression cell line), Jurkat-miR146a-sponge (as miR-146a knock down cell line).

Characterization of the ALDH1B1-dependent transcriptome in SW480 cells by RNA-seq

Project description:The mitochondrial enzyme ALDH1B1 is upregulated in colorectal and pancreatic adenocarcinomas and promotes tumor growth. Using both genetic and chemical perturbations, we have characterized the ALDH1B1-regulated transcriptome in a colorectal cancer cell line. Genes induced by ALDH1B1 include those related to mitochondrial metabolism, stemness, and ribosomal function. These findings implicate ALDH1B1 in cancer metabolism and cancer stem cell maintenance, and they underscore the potential of ALDH1B1 as a therapeutic target.

ANP32e binds histone H2A.Z in a cell cycle-dependent manner and regulates its protein stability in the cytoplasm

Project description:ANP32e, a chaperone of H2A.Z, is receiving increasing attention because of its link to cancer growth and progression. An unanswered question is whether ANP32e regulates H2A.Z dynamics during the cell cycle; if so, this could have clear implications for the proliferation of cancer cells. Using the human U2OS cancer cell line model system, we have confirmed that ANP32e regulates the growth of these cells. ANP32e preferentially interacts with H2A.Z during G1 phase of the cell cycle. Unexpectedly, however, ANP32e does not mediate the removal of H2A.Z from chromatin, is not a stable component of the p400 remodeling complex, and is not strongly associated with chromatin. Instead, most ANP32e is in the cytoplasm. Here, ANP32e preferentially interacts with H2A.Z in G1 phase in response to an increase in H2A.Z protein abundance and regulates its protein stability. This G1-specific interaction between ANP32e and H2A.Z is also observed in the nucleoplasm but is unrelated to any change in H2A.Z abundance. Collectively, these results challenge the idea that ANP32e is involved in regulating the abundance of H2A.Z in chromatin as part of a chromatin remodeling complex. Rather, we propose that ANP32e acts as a molecular chaperone that maintains the soluble pool of H2A.Z by regulating its protein stability and acting as a buffer in response to cell cycle-dependent changes in H2A.Z abundance.
