Modulation of intracellular calcium signaling by microRNA-34a-5p. Cell Death Dis 2018; 9:1008. [PMID: 30262862 PMCID: PMC6160487 DOI: 10.1038/s41419-018-1050-7] [Citation(s) in RCA: 24] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/05/2018] [Revised: 09/10/2018] [Accepted: 09/10/2018] [Indexed: 12/21/2022]
Abstract
Adjusting intracellular calcium signaling is an important feature in the regulation of immune cell function and survival. Here we show that miR-34a-5p, a small non-coding RNA that is deregulated in many common diseases, is a regulator of store-operated Ca2+ entry (SOCE) and calcineurin signaling. Upon miR-34a-5p overexpression, we observed both a decreased depletion of ER calcium content and a decreased Ca2+ influx through Ca2+ release-activated Ca2+ channels. Based on an in silico target prediction we identified multiple miR-34a-5p target genes within both pathways that are implicated in the balance between T-cell activation and apoptosis including ITPR2, CAMLG, STIM1, ORAI3, RCAN1, PPP3R1, and NFATC4. Functional analysis revealed a decrease in Ca2+ activated calcineurin pathway activity measured by a reduced IL-2 secretion due to miR-34a-5p overexpression. Impacting SOCE and/or downstream calcineurin/NFAT signaling by miR-34a-5p offers a possible future approach to manipulate immune cells for clinical interventions.

Abstract
OBJECTIVE Fetal cells cross the feto-maternal barrier and circulate in maternal peripheral blood; thus, this study aimed to show the relationship between clinical evidence in pregnancy and qualitative feto-maternal barrier changes. METHODS The expression of fetal hemoglobin gamma chain messenger RNA (HbF-gamma mRNA) was measured by quantitative reverse transcriptase-polymerase chain reaction (RT-PCR) in maternal peripheral blood. RESULTS HbF-gamma mRNA was detected in all pregnant women after 5 weeks of gestation. In normal pregnancy, there were two peaks at 10 and 40 weeks, and a significant increase 4 weeks prior to the onset of labor. In intrauterine growth restriction (IUGR), preterm delivery and placenta previa, the HbF-gamma mRNA expression was significantly higher than in normal pregnancies. CONCLUSION The expression of HbF-gamma mRNA relative to that of beta-actin mRNA is thought to reflect the real-time leakage of fetal cells into maternal blood.

Abstract
PROBLEM This study was designed to examine immunological changes in maternal peripheral blood and the relationship of these changes with the amount of fetal cells in the blood. METHOD OF STUDY The expression of interleukin-4 (IL-4), IL-8, IL-18 and fetal hemoglobin gamma chain (HbF-gamma chain) messenger RNAs (mRNAs) in maternal peripheral blood was measured by a quantitative reverse transcription-polymerase chain reaction method. RESULTS In maternal peripheral blood, the expression of IL-4 mRNA was up-regulated from the second gestational month (GM) to delivery. The expression of IL-8 and IL-18 mRNAs was down-regulated from the third or fourth GM until the eighth or ninth GM, respectively, and both increased before the onset of labor, though IL-4 mRNA decreased. The expression of IL-8 and IL-18, but not IL-4, mRNAs was correlated with that of HbF-gamma chain mRNA. CONCLUSIONS Immunological interactions between maternal peripheral immune cells and fetal cells appear to be related to the onset of labor.
