MiR-324-5p

Last updated

miR-324-5p is a microRNA that functions in cell growth, apoptosis, cancer, [1] epilepsy, [2] [3] neuronal differentiation, [4] psychiatric conditions, [5] cardiac disease pathology, [6] [1] and more. [7] As a microRNA, it regulates gene expression through targeting mRNAs. Additionally, miR-324-5p is both an intracellular miRNA, meaning it is commonly found within the microenvironment of the cell, and one of several circulating miRNAs found throughout the body. [8] Its presence throughout the body both within and external to cells may contribute to miR-324-5p's wide array of functions and role in numerous disease pathologies – especially cancer – in various organ systems.

Contents

History

miR-324-5p first appeared in literature in a paper published by John Kim et al. in early 2004 that identified 32 entirely new miRNAs from cultured rat cortical neurons using miRNA cloning and RNA analysis. [9] The miRNA quickly gained traction in scientific literature, appearing in articles about the evolutionary conservation of microRNAs, [10] HIV, [11] cancer, [12] and other topics within a few years. Today, the functions and roles of miR-324-5p are still not yet fully characterized. [13]

Structure and targets

miR-324-5p is a reverse strand miRNA, meaning it is produced from the 5' end of the associated RNA, and spans from position 7,223,342 to 7,223,364 on chromosome 17. [14] Its sequence is CGCAUCCCCUAGGGCAUUGGUG. [15] [16]

miRNA forms following cleavage of pre-miRNA at the hairpin loop by the enzyme dicer within the cytosol. Interestingly, both strands of miR-324's pre-miRNA hairpin loop structure, miR-324-5p and miR-324-3p, become active miRNAs with distinct targets and functions. [17] miR-324-5p has between 166 and 469 predicted targets, [18] [19] [14] including regulators of cell growth, proliferation, survival, cytoskeletal structure, ATP transport, and ion channels. [18] Though miR-324-5p is found on chromosome 17, its targets span across all chromosomes. [16]

Functions

Cell growth and survival

miR-324-5p likely regulates cell growth and survival through interaction with multiple pathways. Published research demonstrates that this miRNA interacts with the Hedgehog (HH) signaling pathway via interactions with HH transcription factor Gli1 [20] and HH protein receptor Smo, [21] often contributing to tumorigenesis. miR-324-5p's activating interaction with the protein NfkB also regulates numerous components of cell survival, including cell cycle control, enzyme synthesis, and cell adhesion. [22] In addition, miR-324-5p regulates components of the MAPK pathway, influencing cell growth, proliferation, and survival. Specifically, miR-324-5p downregulates RAF and ERK and is necessary for normal levels of cell growth. Reduced expression leads to increased cell growth and proliferation, and overexpression limits growth, leading to its role in oncogenesis. [23]

miRNA-324-5p targets multiple oncogenes, contributing to both tumorigenesis and tumor suppression in different cancers. Role of miRNA in a cancer cell.svg

Cancer

Both up and downregulation of miR-324-5p is shown to contribute to various types of cancer. [17]

miR-324-5p plays a role in inflammation and tumorigenesis in colorectal cancer through regulation of CUEDC2, which regulates inflammation via interaction with NF-kB signaling. [12] miR-324-5p can inhibit glioma proliferation, [20] suppress hepatocellular carcinoma and nasopharyngeal carcinoma cell invasion, [24] [25] and regulate growth and pathology in multiple myeloma. [26] Additionally, chromosome 17 deletions, which include deletion of miR-324-5p, are present in 10% of multiple myeloma patients and are associated with poorer prognosis. [26]

In contrast, overexpression of miR-324-5p in gastric cancer cells reduces cell death and promotes growth and proliferation. [27] miR-324-5p has also been shown to reduce the viability of gastric cancer cells via downregulation of TSPAN8, and miR-324-5p expression increased apoptosis in these same gastric cancer cells. [28]

Epilepsy

Seizures are characterized by high levels of synchronized neuronal activity. One important regulator of neuronal activity is the hyperpolarizing A-type current mediated by potassium channel KV4.2. [29] miR-324-5p downregulates KV4.2, exacerbating conditions that lead to seizure onset, and downregulation of miR-324-5p in mouse models of epilepsy is seizure-suppressive. [3]

Changes in miRNA expression are seen in epileptogenesis and in other disease pathologies. [30] [31] In epilepsy, miR-324-5p expression has been shown to increase [32] and decrease [33] at different timepoints and loci.

Importantly, miR-324-5p has increased association with the RISC complex following seizure in mice, indicating more suppressive activity. [3] [34]

Overall, this suggests that miR-324-5p plays a role in epileptogenesis via targeting of potassium channel KV4.2.

Cardiac disease

miR-324-5p contributes to cardiac disease pathophysiology and cardiomyocite death through translational inhibition of Mtfr1, leading to reduced mitochondrial fission, apoptosis, and myocardial infarction. [6]

Psychiatric conditions

MiRNA expression profiles are altered in psychiatric conditions, including depression, [5] anxiety, [35] and PTSD. [36] It has been demonstrated that miR-324-5p expression is altered in the brains of suicide victims with depression [5] and in the amygdala, the fear center of the brain, in PTSD. [36] MiRNAs are an underexplored potential biomarker and target for treatment for psychiatric disease. [37]

Future research and potential in medicine

miRNA-324-5p is a relatively new and understudied microRNA. It is an important regulator in several diseases, and its effects span across the body from neuronal dysregulation in seizure to hepatocellular carcinoma and cardiac disease. Because microRNAs have numerous targets, they are capable of regulating multiple pathways and circuits, an ability that may be useful in the treatment of complex disorders like epilepsy in which many subsystems are dysregulated. However, the wide-ranging functions of miRNAs may be limiting as well. microRNA expression modulation could lead to unanticipated physiological effects and not provide adequate specificity. [38]

The miR-9 microRNA, is a short non-coding RNA gene involved in gene regulation. The mature ~21nt miRNAs are processed from hairpin precursor sequences by the Dicer enzyme. The dominant mature miRNA sequence is processed from the 5' arm of the mir-9 precursor, and from the 3' arm of the mir-79 precursor. The mature products are thought to have regulatory roles through complementarity to mRNA.

With the exception of miR-93, these microRNAs are produced from several microRNA gene clusters, which apparently arose from a series of ancient evolutionary genetic duplication events, and also include members of the miR-19, and miR-25 families. These clusters are transcribed as long non-coding RNA transcripts that are processed to form ~70 nucleotide microRNA precursors, that are subsequently processed by the Dicer enzyme to give a ~22 nucleotide products. The mature microRNA products are thought to regulate expression levels of other genes through complementarity to the 3' UTR of specific target messenger RNA.

MicroRNAs function to regulate the expression levels of other genes by several mechanisms. miR-223 is a hematopoietic specific microRNA with crucial functions in myeloid lineage development. It plays an essential role in promoting granulocytic differentiation while also being associated with the suppression of erythrocytic differentiation. miR-223 is commonly repressed in hepatocellular carcinoma and leukemia. Higher expression levels of miRNA-223 are associated with extranodal marginal-zone lymphoma of mucosa-associated lymphoid tissue of the stomach and recurrent ovarian cancer. In some cancers the microRNA-223 down-regulation is correlated with higher tumor burden, disease aggressiveness, and poor prognostic factors. MicroRNA-223 is also associated with rheumatoid arthritis, sepsis, type 2 diabetes, and hepatic ischemia.

mir-31

miR-31 has been characterised as a tumour suppressor miRNA, with its levels varying in breast cancer cells according to the metastatic state of the tumour. From its typical abundance in healthy tissue is a moderate decrease in non-metastatic breast cancer cell lines, and levels are almost completely absent in mouse and human metastatic breast cancer cell lines. Mir-31-5p has also been observed upregulated in Zinc Deficient rats compared to normal in ESCC and in other types of cancers when using this animal model. There has also been observed a strong encapsulation of tumour cells expressing miR-31, as well as a reduced cell survival rate. miR-31's antimetastatic effects therefore make it a potential therapeutic target for breast cancer. However, these two papers were formally retracted by the authors in 2015.
