MicroRNA (miRNA) has shown to enhance or inhibit cell proliferation, differentiation and activity of different cell types in bone tissue. The discovery of miRNA actions and their targets has helped to identify them as novel regulations actors in bone. Various studies have shown that miRNA deregulation mediates the progression of bone-related pathologies, such as osteoporosis. The present review intends to give an exhaustive overview of miRNAs with experimentally validated targets involved in bone homeostasis and highlight their possible role in osteoporosis development...

Post-menopausal condition augments the biological aging process, characterized by multiple metabolic disorders in which bone loss is the most prevalent outcome and usually coupled with sarcopenia. Coexistence of such associated pathogenesis have much worse health outcomes, compared to individuals with osteoporosis only. Pre- and post-natal bone development demands calcium from mother to fetus during pregnancy and lactation leading to a significant maternal skeletal loss. It follows an anabolic phase around weaning during which there is a notable recovery of the maternal skeleton...

Adipose-derived stem cells (ADSCs) provide a novel method for bone tissue regeneration, but their adipogenic tendency limits their therapeutic efficacy. MicroRNAs (miRNAs) have been reported to regulate stem cell differentiation and bone tissue regeneration, but the detailed mechanism is poorly investigated. Our study indicated that inhibition of miR-145-5p enhanced the osteogenic potential of ADSCs and reduced the adipogenic differentiation. Osteogenesis- and adipogenesis-associated genes were detected by qRT-PCR indicating a corresponding result...

Multiple myeloma (MM) malignant plasma cells accumulate in the bone marrow (BM) where their interaction with the microenvironment promotes disease progression and drug resistance. Previously, we have shown that MM cells cocultured with BM-mesenchymal stem cells (MSCs) comodulated cells' phenotype in a MAPKs/translation initiation (TI)-dependent manner. Dissection of the coculture model showed that BM-MSCs secretomes and microvesicles (MVs) participate in this crosstalk. Here, we addressed the role of the BM-MSCs extracellular matrix (ECM)...

MicroRNAs are fine regulators of the whole-body adaptive response but their use as biomarkers is limited by the lack of standardized pre- and post-analytical procedures. This work aimed to compare different normalization approaches for RT-qPCR data analyses, in order to identify the most reliable and reproducible method to analyze circulating miRNA expression profiles in sedentary and highly-trained subjects. As the physically active status is known to affect miRNA expression, they could be effective biomarkers of the homeostatic response...

Inflammation plays an important role in sympathetic neural remodeling induced by myocardial infarction (MI). MiR-155 is a vital regulator of inflammatory responses, and macrophage-secreted miR-155 promotes cardiac fibrosis and hypertrophy. However, whether miR-155 influences MI-induced sympathetic neural remodeling is not clear. Therefore, we examined the role of miR-155 in MI-induced sympathetic neural remodeling and the related mechanisms in both an mouse model and in lipopolysaccharide (LPS)-stimulated bone marrow-derived macrophages (BMDMs)...

Osteosarcoma (OS) is the most common primary bone malignancy. It predominantly occurs in adolescents, but can develop at any age. The age at diagnosis is a prognostic factor of OS, but the molecular basis of this remains unknown. The current study aimed to identify age‑induced differentially expressed genes (DEGs) and potential molecular mechanisms that contribute to the different outcomes of patients with OS. Microarray data (GSE39058 and GSE39040) obtained from the Gene Expression Omnibus database and used to analyze age‑induced DEGs to reveal molecular mechanism of OS among different age groups (<20 and >20 years old)...

Bone formation and regeneration is a multistep complex process crucially determined by the formation of blood vessels in the growth plate region. This is preceded by the expression of growth factors, notably the vascular endothelial growth factor (VEGF), secreted by osteogenic cells, as well as the corresponding response of endothelial cells, although the exact mechanisms remain to be clarified. Thereby, coordinated coupling between osteogenesis and angiogenesis is initiated and sustained. The precise interplay of these two fundamental processes is crucial during times of rapid bone growth or fracture repair in adults...

Insulin resistance is the major pathological characteristic of type 2 diabetes and the elderly often develop insulin resistance. However, the deep-seated mechanisms for aging-related insulin resistance remain unclear. Here, we showed that nano-sized exosomes released by bone marrow mesenchymal stem cells (BM-MSCs) of aged mice could be taken up by adipocytes, myocytes, and hepatocytes, resulting in insulin resistance both in vivo and in vitro. Using microRNA (miRNA) array assays, we found that the amount of miR-29b-3p was dramatically increased in exosomes released by BM-MSCs of aged mice...

Phenotypic variation in skeletal traits and diseases is the product of genetic and environmental factors. Epigenetic mechanisms include information-containing factors, other than DNA sequence, that cause stable changes in gene expression and are maintained during cell divisions. They represent a link between environmental influences, genome features, and the resulting phenotype. The main epigenetic factors are DNA methylation, posttranslational changes of histones, and higher-order chromatin structure. Sometimes non-coding RNAs, such as microRNAs (miRNAs) and long non-coding RNAs (lncRNAs), are also included in the broad term of epigenetic factors...

Acute lymphoblastic leukemia (ALL) is a malignant transformation with uncontrolled proliferation of lymphoid precursor cells within bone marrow including a dismal prognosis after relapse. Survival of a population of quiescent leukemia stem cells (LSCs, also termed leukemia-initiating cells (LICs)) after treatment is one of the relapse reasons in Ph+ ALL patient. MicroRNAs (miRNAs) are known as highly conserved 19-24 nucleotides non-protein-coding small RNAs that regulate the expression of human genes. miRNAs are often involved in the tuning of hematopoiesis...

A number of evidences suggest that microRNAs are involved in the adipogenic commitment of mesenchymal stem cells (MSCs). Recent studies have investigated that miR-199a-3p played a pivotal role in adipocyte differentiation. However, the detailed mechanism in this complex biological process remains largely unknown. In current study, we found that the expression of miR-199a-3p was gradually increased during adipogenic differentiation of bone marrow derived mesenchymal stem cells (BMMSCs). Enhanced expression of miR-199a-3p promoted adipogenesis, whereas silence of miR-199a-3p rescued BMMSCs from adipogenic commitment...

Osteoarthritis (OA) is a naturally occurring, irreversible disorder and a major health burden. The disease is multifactorial, involving both physiological and mechanical processes, but calcium crystals have been associated intimately with its pathogenesis. This study tested the hypothesis that these crystals have a detrimental effect on the differentiation of osteoclasts and bone homeostasis. This study employed an osteoblastosteoclast coculture system that resembles in vivo osteoblastdependent osteoclast differentiation along with Ca2+-phosphate-coated culture dishes...

The small non-coding microRNAs (miRNAs) are post-transcription regulators that modulate diverse cellular process in bone cells. Because optimal miRNA targeting is essential for their function, single-nucleotide polymorphisms (SNPs) within or proximal to the loci of miRNA (miR-SNPs) or mRNA (PolymiRTS) could potentially disrupt the miRNA-mRNA interaction, leading to changes in bone metabolism and osteoporosis. Recent human studies of skeletal traits using miRNA profiling, genomewide association studies, and functional studies started to decipher the complex miRNA regulatory network...

MicroRNAs of the miR-16 and miR-34 families have been reported to inhibit cell cycle progression and their loss has been linked to oncogenic transformation. Utilizing a high-throughput, genome-wide screen for miRNAs and mRNAs that are differentially regulated in osteosarcoma (OS) cell lines, we report that miR-449a and miR-424, belonging to the miR-34 and miR-16 families, respectively, target the major S/G2 phase cyclin, cyclin A2 (CCNA2) in a bipartite manner. We found that the 3' UTR of CCNA2 is recognized by miR-449a whereas the CCNA2 coding region is targeted by miR-424...

Osteosarcoma (OS) is the most common primary malignant bone tumor. Numerous studies have strongly implicated the ectopic expression of microRNAs (miRNAs/miRs), including miR-885-5p, which is aberrantly expressed in several cancer types, in multiple cancer-related processes. However, the role of miR-885-5p in OS remains unknown. In the present study, it was found that the expression of miR-885-5p was markedly upregulated in OS cell lines and clinical tissues. Moreover, high expression of miR-885-5p was significantly associated with the development of OS...

Osteosarcoma (OS) is the most common malignant bone tumor. In cancer cells, autophagy is related to epithelial-to-mesenchymal transition (EMT). Although microRNA (miR)-506-3p has been demonstrated to act as a tumor suppressor in OS, its role in regulating the EMT process and autophagy remains unknown. The results showed that miR-506-3p directly inhibited the expression of sphingosine kinase 1 (SPHK1) in 143B and SaOS-2 cells. The invasive capability of OS cells was reduced following miR-506-3p mimics transfection, and restored when SPHK1 was overexpressed simultaneously...
