Abstract
Colon cancer is the world's fourth leading cause of death. It is cancer of the latter part of the large intestine, i.e. the colon. Chronic inflammation over a long period also leads to the development of cancer. Cancer in the colon region is arduous to diagnose and is detected at a later stage when it metastasizes to other parts of the body like the liver, lungs, peritoneum, etc. Colon cancer is a great example of solid tumours associated with chronic inflammation. Although conventional therapies are effective, they lose their effectiveness beyond a certain point. Relapse of the disease occurs frequently. RNA interference (RNAi) is emerging as a great tool to specifically attack the cancer cells of a target site like the colon. RNAi deals with epigenetic changes made in the defective cells which ultimately leads to their death without harming the healthy cells. In this review, two types of epigenetic modulators have been considered, namely siRNA and miRNA, and their effect on interleukins. Interleukins, a class of cytokines, are major inflammatory responses of the body that are released by immune cells like leukocytes and macrophages. Some of these interleukins are pro-inflammatory, thereby promoting inflammation which eventually causes cancer. RNAi can prevent colon cancer by inhibiting pro-inflammatory interleukins.

MicroRNA-574-3p Regulates HIF-α Isoforms Promoting Gastric Cancer Epithelial-Mesenchymal Transition via Targeting CUL2. Dig Dis Sci 2022; 67:3714-3724. [PMID: 34655362 DOI: 10.1007/s10620-021-07263-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/24/2020] [Accepted: 09/21/2021] [Indexed: 12/09/2022]
Abstract
BACKGROUND Gastric cancer (GC) is the third leading cause of cancer-related deaths worldwide. MicroRNAs (miRNAs) have been widely validated as potential biomarkers for cancer treatment and diagnosis. AIMS This paper intends to study the effect and specific mechanism of miR-574-3p/CUL2 axis in GC. METHODS The miR-574-3p expression in GC tissues and cell lines was analyzed by reverse transcription polymerase chain reaction (RT-PCR). GC cell (N87) proliferation, migration and invasion were determined by the Brdu assay and Transwell assay, respectively. The tumor xenotransplantation model was established in vivo to test the effect of miR-574-3p or Cullin 2 (CUL2) on tumor growth. The relationship between miR-574-3p and CUL2 was predicated by bioinformatic analysis and verified by dual-luciferase reporter assay and RIP experiment. The expression of CUL2, hypoxia-induced transcription factor-1α (HIF-1α) as well as E-cadherin, Snail and Vimentin was monitored by western blot and immunohistochemistry. RESULTS miR-574-3p was overexpressed in GC tissues and cells. Forced upregulation of miR-574-3p enhanced proliferation, migration, invasion and epithelial-mesenchymal transition (EMT) of GC cells (N87), while downregulation of miR-574-3p resulted in reverse effects. Additionally, miR-574-3p promoted N87 cells growth and EMT in vivo. CUL2 was negatively regulated by miR-574-3p in N87 cells, and upregulation of CUL2 repressed the malignant behaviors of N87 cells. Moreover, CUL2 directly interacted with HIF-1α and suppressed HIF-1α expression both in vitro and in vivo. CONCLUSIONS miR-574-3p targeted CUL2 to upregulate HIF-1α, thus facilitating the progression of GC.

Chem Biol Interact 2022; 354:109832. [PMID: 35085581 DOI: 10.1016/j.cbi.2022.109832] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/27/2021] [Revised: 01/09/2022] [Accepted: 01/21/2022] [Indexed: 01/21/2023]
Abstract
Piperlongumine is a herbal drug, with well-known anti-microbial and anti-neoplastic properties. The anti-carcinogenic potential of piperlongumine has been extensively explored for breast, colorectal, lungs, pancreatic, prostate, and oral carcinoma. However, a few numbers of studies are available on its bio-activity in osteosarcoma. Therefore, the present study aimed at exploring the therapeutic potential and possible mechanisms of action of piperlongumine in three human osteosarcoma cell lines in-vitro. The cytotoxicity of piperlongumine was determined by MTT assay, which shows dose and time-dependent inhibition of MG-63, 143B and KHOS/NP cells. Piperlongumine arrest the cells in G2/M phase of cell cycle and increases reactive oxygen species production, which possibly leads to lethal oxidative stress and apoptosis. Piperlongumine treatment significantly upregulated the expression of genes BAX, P21, P53, and SMAD4; while the BCL-2, SURVIVIN, TNFA, and NFKB genes expression was found down-regulated. Furthermore, piperlongumine exposure inhibited the migration of osteosarcoma cells as the expression of migration marker genes CDH2, CTNNB1, FN1, and TWIST were found to be down-regulated. The drug combination studies show the synergistic effect of piperlongumine with the conventional chemotherapeutic drug doxorubicin in osteosarcoma cells. Taken together, the above results suggest that PL displays anticancer properties against osteosarcoma and can be used as a therapeutic agent for osteosarcoma treatment in clinical settings.

Abstract
Blood disorders include a wide spectrum of blood-associated malignancies resulting from inherited or acquired defects. The ineffectiveness of existing therapies against blood disorders arises from different reasons, one of which is drug resistance, so different types of leukemia may show different responses to treatment. Leukemia occurs for a variety of genetic and acquired reasons, leading to uncontrolled proliferation in one or more cell lines. Regarding the genetic defects, oncogene signal transducer and activator of transcription (STAT) family transcription factor, especially STAT3, play an essential role in hematological disorders onset and progress upon mutations, dysfunction, or hyperactivity. Besides, microRNAs, as biological molecules, has been shown to play a dual role in either tumorigenesis and tumor suppression in various cancers. Besides, a strong association between STAT3 and miRNA has been reported. For example, miRNAs can regulate STAT3 via targeting its upstream mediators such as IL6, IL9, and JAKs or directly binding to the STAT3 gene. On the other hand, STAT3 can regulate miRNAs. In this review study, we aimed to determine the role of either microRNAs and STAT3 along with their effect on one another's activity and function in hematological malignancies.

Abstract
Pancreatic cancer (PC) is among the most notorious malignancies worldwide. Long noncoding RNA (lncRNA) repulsive guidance molecule bone morphogenetic protein (BMP) coreceptor b antisense RNA 1 (RGMB-AS1) was an oncogene in glioma. However, the RGMB-AS1 function in PC remains largely unknown. Herein, quantitative real-time polymerase chain reaction was performed to analyze the expression of RGMB-AS1. We determined RGMB-AS1 influence on PC cell malignant behaviors via functional assays. Besides, we applied subcellular fractionation and fluorescence in situ hybridization (FISH) assays to confirm the cellular distribution of RGMB-AS1 in PC cells. We used mechanism assays to detect the regulatory axis of RGMB-AS1 in PC cells. Briefly, the level of RGMB-AS1 expression in PC cells was abnormally high. RGMB-AS1 knockdown impeded PC cell proliferation and migration, but induced cell apoptosis, and RGMB-AS1 overexpression led the opposite consequences. RGMB-AS1 acted as a competing endogenous RNA (ceRNA) to sequester miR-574-3p and thereby regulated Pim-3 proto-oncogene, serine/threonine kinase (PIM3) expression. Conclusively, our work revealed the cancer-promoting function of RGMB-AS1 in PC and that the regulatory mechanism of the RGMB-AS1/miR-574-3p/PIM3 axis might contribute to novel biomarker development in PC treatment.NEW & NOTEWORTHY RGMB-AS1 promotes PC cell proliferation, elevates PC cell migration capacity, inhibits PC cell apoptosis, and promotes PC cell proliferation and migration but inhibits cell apoptosis via targeting miR-574-3p. PIM3 is directly targeted by miR-574-3p.

Abstract
Numerous studies have shown that the expression of circular RNA (circRNA) is closely related to the malignant progression of cancer. However, the role of circ-MFN2 in colorectal cancer (CRC) is unclear. Our study aims to explore the role and mechanism of circ-MFN2 in CRC progression. The relative expression levels of circ-MFN2, microRNA (miR)-574-3p and insulin-like growth factor 1 receptor (IGF1R) were detected by quantitative real-time polymerase chain reaction (qRT-PCR). Cell viability was determined using 3-(4, 5-dimethyl-2 thiazolyl)-2, 5-diphenyl-2-H-tetrazolium bromide (MTT) assay. The colony number and radioresistance of cells were assessed using colony formation assay. Moreover, the migration and invasion of cells were measured using transwell assay. Tumor xenograft model was constructed to evaluate the effect of circ-MFN2 knockdown on CRC tumor growth. Furthermore, dual-luciferase reporter assay was used to verify the interaction between miR-574-3p and circ-MFN2 or IGF1R. In addition, the protein level of IGF1R was evaluated by western blot (WB) analysis. Circ-MFN2 expression was elevated in CRC tissues and cells. Knockdown of circ-MFN2 restrained the proliferation, migration, invasion, and radioresistance of CRC cells in vitro. Furthermore, silenced circ-MFN2 also reduced the tumor volume and weight of CRC in vivo. MiR-574-3p could be sponged by circ-MFN2, and its inhibitor reversed the suppression effect of circ-MFN2 silencing on CRC progression. Moreover, IGF1R was a target of miR-574-3p, and its overexpression reversed the inhibition effect of miR-574-3p mimic on CRC progression. In addition, circ-MFN2 could positively regulate IGF1R expression by sponging miR-574-3p. Our results revealed that circ-MFN2 promoted the proliferation, metastasis and radioresistance of CRC through regulating the miR-574-3p/IGF1R axis, suggesting that circ-MFN2 might be a novel therapeutic biomarker for CRC.

Abstract
Interleukin (IL)-18 has a clear antitumor effect; however, its mechanisms of action are not understood in patients with colorectal cancer (CRC). Here, we investigated the potential mechanism of IL-18 in CRC. The results showed that IL-18 treatment alone had no effect on HCT116 cells apoptosis, whereas IL-18 in the presence of natural killer (NK) cells resulted in apoptosis and inhibition of cells proliferation in vitro. Profiling of miRNA expression following coculture with NK cells and treatment with IL-18 resulted in significant downregulation of miR-574-3p expression and upregulated expression of the target gene transforming growth factor beta 1 (TGF-β1). miR-574-3p binds to TGF-β1, and miR-574-3p overexpression increased the proliferation and decreased the apoptotic rate of HCT116 cells in NK cells coculture with IL-18 treatment; overexpression of TGF-β1 restored the effect of miR-574-3p overexpression. The miRNA profile of HCT116 undergoes significant alteration before and after coculturing with NK cells and treatment with IL-18. IL-18 alone did not affect HCT116 cells apoptosis but did promote the antitumor ability of NK cells in coculture with HCT116 cells via the miR-574-3p/TGF-β1 axis. Our study suggested that IL-18 can be a new potential target for cancer immunotherapy for CRC.

MiRNA-574-3p inhibits cell progression by directly targeting CCND2 in colorectal cancer. Biosci Rep 2020; 39:221158. [PMID: 31729531 PMCID: PMC6911158 DOI: 10.1042/bsr20190976] [Citation(s) in RCA: 16] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/19/2019] [Revised: 11/05/2019] [Accepted: 11/14/2019] [Indexed: 12/17/2022] Open
Abstract
Colorectal cancer (CRC) remains the candidate for one of the typical types of malignant tumors of in gastrointestinal tract all around the world, which leads to tremendous death and ranks as the top leading death of cancer. Recently, microRNAs have emerged as double-edged sword in numerous cancers. This investigation aims to discuss the regulative role of microRNA-574-3p (miR-574-3p), elucidating its molecular mechanism and clinical significance in CRC. Herein, it revealed to us that miR-574-3p was lowly expressed in CRC tissues in comparison with the matched paracarcinoma tissues. In addition, transfection of SW480 and HT29 cells with miR-574-3p mimics prohibited the post-transcriptional expression of Cyclin D2 (CCND2), which then significantly blocked cell growth and cell migration, yet triggered cell apoptosis. Also, dual-luciferase reporter assays proved the role of CCND2 as the targeted gene for miR-574-3p. miR-574-3p overexpression prohibited the activity of CCND2 in SW480 and HT29 cells. Silencing of CCND2 in SW480 and HT29 CRC cell lines leading to reduced cell proliferative and migrative rates, and enhanced apoptotic rate. The suppressive effects of elevation of miR-574-3p on the proliferation of the human CRC cells and promotive effects on cell apoptosis by targeting CCND2 were further illustrated in the in vitro studies. Thus, we hypothesize that miR-574-3p may be served as a prospective therapeutic candidate for CRC.

Abstract
Liver cancer is one of the most common and aggressive tumors, and usually leads to a poor clinical outcome. Increasing evidence has demonstrated the important functions of microRNAs (miRs) in tumor progression. miR-574-3p has been reported as a tumor suppressor and potential therapeutic target in various types of cancer. However, the underlying mechanism of the effects of miR-574-3p in liver cancer remains unknown. In the present study, reverse transcription-quantitative PCR was performed to detect miR-574-3p expression in liver cancer tissues, and the influence of miR-574-3p on cell growth was evaluated using the Cell Counting Kit-8 assay, and cell migration and flow cytometry analyses. The present study revealed that miR-574-3p expression was downregulated in liver cancer tissues and cell lines. miR-574-3p overexpression, achieved by transfecting miR-574-3p mimics into liver cancer cells, reduced cell proliferation and migration, and promoted cell apoptosis. Mechanistically, ADAM metallopeptidase domain 28 (ADAM28) was identified as a miR-574-3p target via binding to the 3'-untranslated region of the ADAM28 mRNA. Gain-of-function of miR-574-3p downregulated the expression levels of ADAM28 in liver cancer cells. Additionally, overexpression of ADAM28 significantly attenuated the suppressive effect of miR-574-3p on the growth of liver cancer cells. The present results provide novel insights into the function of the miR-574-3p/ADAM28 signaling pathway in liver cancer.

Abstract
BACKGROUND MicroRNA (miR)s are promising diagnostic biomarkers of cancer. Recent next generation sequencer (NGS) studies have found that isoforms of micro RNA (isomiR) circulate in the bloodstream similarly to mature micro RNA (miR). We hypothesized that combination of circulating miR and isomiRs detected by NGS are potentially powerful cancer biomarker. The present study aimed to investigate their application in esophageal cancer. METHODS Serum samples from patients with esophageal squamous cell carcinoma (ESCC) and age and sex matched healthy control (HC) individuals were investigated for the expression of miR/isomiRs using NGS. Candidate miR/isomiRs which met the criteria in the 1st group (ESCC = 18 and HC = 12) were validated in the 2nd group (ESCC = 30 and HC = 30). A diagnostic panel was generated using miR/isomiRs that were consistently confirmed in the 1st and 2nd groups. Accuracy of the panel was tested then in the 3rd group (ESCC = 18 and HC = 18). Their use was also investigated in 22 paired samples obtained pre- and post-treatment, and in patients with esophageal adenocarcinoma (EAD) and high-grade dysplasia (HGD). RESULTS Twenty-four miR/isomiRs met the criteria for diagnostic biomarker in the 1st and 2nd group. A multiple regression model selected one mature miR (miR-30a-5p) and two isomiRs (isoform of miR-574-3p and miR-205-5p). The index calculated from the diagnostic panel was significantly higher in ESCC patients than in the HCs (13.3±8.9 vs. 3.1±1.3, p<0.001). The area under the receiver operating characteristics (ROC) curves of the panel index was 0.95. Sensitivity and specificity were 93.8%, and 81% in the 1st and 2nd groups, and 88.9% and 72.3% in the 3rd group, respectively. The panel index was significantly lower in patients with EAD (6.2±4.5) and HGD (4.2±1.7) than in those with ESCC and was significantly decreased at post-treatment compared with pre-treatment (6.2±5.6 vs 11.6±11.5, p = 0.03). CONCLUSION Our diagnostic panel had high accuracy in the diagnosis of ESCC. MiR/isomiRs detected by NGS could serve as novel biomarkers of ESCC.

Abstract
Background Pancreatic cancer is an extensively concerned human malignancy around the globe, yet the potential therapeutic target remains to be further determined. MicroRNA and LncRNA have been reported to be involved in progression of pancreatic cancer, while the biological role of microRNA-574-3p (miR-574-3p) and FAM66C in pancreatic cancer development is poorly investigated. Methods Quantitative real-time PCR (qPCR) analysis was employed to detect the expression of miR-574-3p and FAM66C in pancreatic normal or cancerous tissues and cells. The proliferative and apoptosis signaling molecules were also examined via qPCR and western blot separately. Additionally, cell proliferation and apoptosis assay were performed via CCK8, colony formation and Annexin V-FITC apoptosis assay. Interaction between miR-574-3p and FAM66C was interrogated by luciferase reporter assay and RNA immunoprecipitation. Even more, a pancreatic cancer xenograft mice assay was implemented to illustrate the coordinating role of miR-574-3p and FAM66C in pancreatic cancer proliferation. Results We found that levels of miR-574-3p were significantly higher in cancer tissues and cells compared to normal (P<0.05). Remarkably, the results indicated that depletion of miR-574-3p inhibited proliferation and promoted apoptosis of human pancreatic cancer cell lines. Additionally, FAM66C was demonstrated to interact with miR-574-3p and inhibit its expression.

Abstract
Osteosarcoma (OS) is a bone tumor of mesenchymal origin, most frequently occurring during the rapid growth phase of long bones, and usually located in the epiphyseal growth plates of the femur or the tibia. Its most common feature is genome disorganization, aneuploidy with chromosomal alterations, deregulation of tumor suppressor genes and of the cell cycle, and an absence of DNA repair. This suggests the involvement of surveillance failures, DNA repair or apoptosis control during osteogenesis, allowing the survival of cells which have undergone alterations during differentiation. Epigenetic events, including DNA methylation, histone modifications, nucleosome remodeling and expression of non-coding RNAs have been identified as possible risk factors for the tumor. It has been reported that p53 target genes or those genes that have their activity modulated by p53, in addition to other tumor suppressor genes, are silenced in OS-derived cell lines by hypermethylation of their promoters. In osteogenesis, osteoblasts are formed from pluripotent mesenchymal cells, with potential for self-renewal, proliferation and differentiation into various cell types. This involves complex signaling pathways and multiple factors. Any disturbance in this process can cause deregulation of the differentiation and proliferation of these cells, leading to the malignant phenotype. Therefore, the origin of OS seems to be multifactorial, involving the deregulation of differentiation of mesenchymal cells and tumor suppressor genes, activation of oncogenes, epigenetic events and the production of cytokines.

Abstract
Despite development in therapies, the high recurrence and low positivity of biomarkers for diagnosis still result in glioma with high mortality. In this study, we aimed to identify a potential miRNA signature to evaluate the effect of radiotherapy in glioma patients. MicroRNA (miRNA) sequencing was performed on miRNAs isolated from serum exosomes in a cohort of glioma patients before and after radiotherapy. A total of 18 up-regulated differentially expressed (DE) miRNAs and 16 down-regulated DE miRNAs were identified. Subsequently, the target genes of DE miRNAs were predicted based on multiple miRNA-target databases. Further, it was indicated that these targets were primarily involved in metabolic process, p53 signaling pathway and cancer pathways, suggesting that these miRNAs play a crucial role in glioma by regulating targets and affect the occurrence and development of the disease. In general, this study presented the variation of miRNAs in blood exosomes before and after radiotherapy. It can not only be helpful for the diagnosis of glioma, but also find new candidate biomarkers for monitoring the condition and evaluating the efficacy of radiotherapy in glioma. It provides a new idea for the diagnosis, treatment and prognosis evaluation of glioma.

Abstract
Coronary artery disease (CAD) is one of the biggest threats to human life. Circulating microRNAs (miRNAs) have been reported to be linked to the pathogenesis of CAD, indicating the possible role in CAD diagnosis. The present study aimed to explore the expression profile of plasma miRNAs and estimate their value in diagnosis for CAD. 67 Non‐CAD control subjects and 88 CAD patients were enrolled. We conducted careful evaluation by RT‐PCR analysis, Spearman rank correlation coefficients analysis, Receiver Operating Characteristic (ROC) curves analysis and so on. The plasma levels of six miRNAs known to be related to CAD were measured and three of them showed obvious expression change. Circulating miR‐29a‐3p, miR‐574‐3p and miR‐574‐5p were all significantly increased. ROC analysis revealed the probability of the three miRNAs as biomarkers with AUCs (areas under the ROC curve) of 0.830, 0.792 and 0.789, respectively. They were significantly correlated with each other in CAD patients, suggesting the possibility of joint diagnosis. The combined AUC was 0.915, much higher than each single miRNA. Therefore, our study revealed three promising biomarkers for early diagnosis of CAD. The combination of these miRNAs may act more effectively than individual ones for CAD diagnosis.

Abstract
Strand-selection is the final step of microRNA biogenesis in which functional mature miRNAs are generated from one or both arms of precursor. The preference of strand-selection is diverse during development and tissue formation, however, its pathological effect is still unknown. Here we find that two miRNA arms from the same precursor, miR-574-5p and miR-574-3p, are inversely expressed and play exactly opposite roles in gastric cancer progression. Higher-5p with lower-3p expression pattern is significantly correlated with higher TNM stages and poor prognosis of gastric cancer patients. The increase of miR-574-5p/-3p ratio, named miR-574 arm-imbalance is partially due to the dynamic expression of their highly complementary targets in gastric carcinogenesis, moreover, the arm-imbalance of miR-574 is in turn involved and further promotes gastric cancer progression. Our results indicate that miR-574 arm-imbalance contribute to gastric cancer progression and re-modification of the miR-574-targets homeostasis may represent a promising strategy for gastric cancer therapy. Functional miRNAs derived from the 5p or 3p arm of some miRNA duplexes have opposite roles in cancer progression. Here, the authors show that oncogenic miR-574-5p has greater preference in aggressive gastric cancer as compared with miR-574-3p and this arm preference is partly dependent on complementary targets mediated miRNA decay.

Milk-derived miRNA profiles elucidate molecular pathways that underlie breast dysfunction in women with common genetic variants in SLC30A2. Sci Rep 2019; 9:12686.

Abstract
Studies in humans and pre-clinical animal models show milk-derived miRNAs reflect mammary gland function during lactation. The zinc transporter SLC30A2/ZnT2 plays a critical role in mammary gland function; ZnT2-null mice have profound defects in mammary epithelial cell (MEC) polarity and secretion, resulting in sub-optimal lactation. Non-synonymous genetic variation in SLC30A2 is common in humans, and several common ZnT2 variants are associated with changes in milk components that suggest breast dysfunction in women. To identify novel mechanisms through which dysfunction might occur, milk-derived miRNA profiles were characterized in women harboring three common genetic variants in SLC30A2 (D103E, T288S, and Exon 7). Expression of ten miRNAs differed between genotypes, and contributed to distinct spatial separation. Studies in breast milk and cultured MECs confirmed expression of ZnT2 variants alters abundance of protein levels of several predicted mRNA targets critical for breast function (PRLR, VAMP7, and SOX4). Moreover, bioinformatic analysis identified two novel gene networks that may underlie normal MEC function. Thus, we propose that genetic variation in genes critical for normal breast function such as SLC30A2 has important implications for lactation performance in women, and that milk-derived miRNAs can be used to identify novel mechanisms and for diagnostic potential.

Abstract
Diabetes can cause intervertebral disc degeneration by accelerating apoptosis and senescence of nucleus pulposus mesenchymal stem cells (NPMSCs). The aim of this study was to determine the effect of umbilical cord mesenchymal stem cells (UCMSCs) conditioned medium on high glucose (HG) induced degradation of NPMSCs produced extracellular matrix. NPMSCs were isolated from the inner intervertebral disc tissue using type XI collagenase digestion. According to Annexin V/propidium iodide (PI) flow cytometry analysis; HG leads to an increase in the rate of NPMSCs apoptosis. HG injury also resulted in a marked decrease in the percentage of cells in G0/G1 phase and an increase in cells in S and G2/M phases, indicating that HG induces cell cycle arrest of NPMSCs. Treatment with MSC-CM abolished the effect of HG on cell senescence. HG also significantly inhibited collagen II and aggrecan expression in NPMSCs. After MSC-CM treatment, the expression of these two extracellular matrix components was restored. Exposure to HG resulted in phosphorylation of p38 MAPK, while the levels of total p38 MAPK were not affected. When treated with MSC-CM, phosphorylated p38 MAPK levels of NPMSCs were lower than those without CM treatment. Our data also showed that p38 MAPK inhibitor SB203580 can attenuated phosphorylation of p38 MAPK and resumed the collagen II and aggrecan expression in NPMSCs. In summary, this study demonstrated that MSC-CM has the potential to alleviate HG induced extracellular matrix degradation via the p38 MAPK pathway.

Abstract
MicroRNA-574-3p (miR-574-3p) has different roles in different cancer types. However, the exact regulation mechanism of miR-574-3p in gastric cancer (GC) progression remains unclear. Thus, we aimed to evaluate the role of miR-574-3p in GC metastasis. We investigated the mechanism via which miR-574-3p regulated cancer cell migration and invasion to determine the relationship between epithelial mesenchymal transition (EMT) and drug resistance. Our results indicated that human GC cell line SGC7901 cells were more sensitive to cisplatin (DDP), but SGC7901 cisplatin-resistant cells (SGC7901/DDP) were more resistant to DDP and had mesenchymal characteristics. In addition, miR-574-3p overexpression up-regulated E-cadherin expression, and concomitantly down-regulated the expression of vimentin. We also identified zinc finger E-box binding homeobox transcription factor 1 (ZEB1), a crucial EMT inducer gene, as a new target of miR-574-3p. In fact, miR-574-3p bound the 3' untranslated region (3'-UTR) of ZEB1, regulating expression of this transcription factor at both the mRNA and protein levels. Furthermore, miR-574-3p overexpression reduced the migratory and invasive properties of the SGC7901/DDP cells and inhibited cisplatin (DDP) resistance in vitro and in vivo. In conclusion, the results indicated that miR-574-3p inhibited the EMT and enhanced cisplatin sensitivity in GC cells by suppressing ZEB1. These results provide further evidence for the critical roles of miR-574-3p and ZEB1 in invasion and migration regulation characteristics of GC cells.

Abstract
The present study aimed to elucidate the potential roles and regulatory mechanism of microRNA (miR)-574-3p in the development of chronic myeloid leukemia (CML). The expression of miR-574-3p in peripheral blood obtained from patients with CML was examined. Subsequently, miR-574-3p was overexpressed and suppressed in CML K562 cells to further investigate the effects of miR-574-3p on cell proliferation, and apoptosis. Furthermore, a luciferase reporter assay was performed to investigate whether interleukin-6 (IL-6) was a target of miR-574-3p. In addition, the regulatory association between miR-574-3p and the IL-6/Janus kinase (JNK)/signal transducer and activator of transcription-3 (STAT3) signaling pathway was explored. The expression of miR-574-3p in the peripheral blood obtained from patients with CML was significantly lower compared with that in healthy controls. Overexpression of miR-574-3p significantly inhibited the proliferation and induced the apoptosis of K562 cells, whereas suppression of miR-574-3p exhibited opposite effects. In addition, IL-6 was identified to be a direct target of miR-574-3p. Overexpression of IL-6 significantly promoted the proliferation and inhibited the apoptosis of K562 cells. Furthermore, overexpression of miR-574-3p inhibited the activation of the JAK/STAT3 signaling pathway, which was rescued by overexpression of IL-6. The results of the current study indicate that miR-574-3p overexpression may serve an important role in inhibiting proliferation and inducing apoptosis of K562 cells via suppression of IL-6/JAK/STAT3 signaling pathway activation. miR-574-3p may serve as a potential therapeutic target for CML.

Abstract
BACKGROUND AND OBJECTIVE Propofol, an intravenous anesthetic agent, has been found to inhibit growth of breast cancer cells. However, the mechanisms underlying the antitumor are not known. A recent report has found that propofol could significantly downregulate miR-24 expression in the human malignant cancers. In breast cancer cells, overexpression of miR-24 promotes cell proliferation and inhibits cell apoptosis by downregulation of p27. The miR-24 has been reported to be overexpressed in breast cancer and breast cancer cell lines. In the present study, we hypothesized that propofol induces apoptosis of breast cancer cells by miR-24/p27 signal pathway. METHODS Breast cancer MDA-MB-435 cells were exposed to propofol (10 μM) for 6 hr and cell death was assessed using TUNEL staining, Flow cytometry and cleaved caspase-3 expression. microRNA-24 (miR-24) expression was assessed using quantitative reverse transcription polymerase chain reaction (qRT-PCR). miR-24 was overexpressed using a miR-24 mimic. P27 was knocked down using a small interfering RNA. p27 and cleaved caspase-3 expression was assessed by Western blot. RESULTS MDA-MB-435 exposed to propofol showed a significant increase in apoptotic cells, followed by the downregulation of miR-24, upregulation of p27 expression and cleaved caspase-3 expression. Targeting p27 inhibits propofol-induced cell apoptosis; miR-24 overexpression decreased propofol-induced cell apoptosis, cleaved caspase-3 and p27 expression. CONCLUSIONS Propofol inducescell death in MDA-MB-435 cells via inactivation of miR-24/p27 signal pathway.

Abstract
MicroRNAs (miRNAs) are novel regulatory factors that play important roles in numerous cellular processes through the posttranscriptional regulation of gene expression. Recently, deregulation of the miRNA-mediated mechanism has emerged as an important pathological factor in osteoporosis. However, a detailed molecular mechanism between miRNAs and osteoporosis is still not available. In this review, the roles of miRNAs in the regulation of cells related to bone homeostasis as well as miRNAs that deregulate in human or animal are discussed. Moreover, the miRNAs that act as clusters in the biology of cells in the bone microenvironment and the difference of some important miRNAs for bone homeostasis between bone and other organs are mentioned. Overall, miRNAs that contribute to the pathogenesis of osteoporosis and their therapeutic potential are considered.

Abstract
Accumulated evidence has demonstrated that dysregulation of microRNAs (miRNAs) contributes to tumourigenesis and tumour development of glioblastoma multiforme (GBM). Therefore, miRNAs may be promising candidates in the development of prognosis biomarkers and effective therapeutic targets for patients with GBM. A number of studies have reported that miRNA‑574 (miR‑574) is aberrantly expressed in multiple types of human cancers. However, the expression pattern, biological functions and molecular mechanism of miR‑574 in GBM are yet to be elucidated. Therefore, the present study aimed to determine the expression level and biological functions of miR‑574 in GBM and the underlying molecular mechanisms. In the present study, miR‑574 levels were measured by reverse transcription‑quantitative polymerase chain reaction (RT‑qPCR) and were demonstrated to be significantly downregulated in human GBM tissues and cell lines. Functional experiments indicated that restored expression of miR‑574 using mimics led to the inhibition of the cell proliferation and invasion of GBM cells, as determined by Cell Counting kit‑8 and Matrigel invasion assays, respectively. In addition, bioinformatics analysis predicted that zinc finger E‑box‑binding homeobox 1 (ZEB1) may be a target of miR‑574. Subsequent RT‑qPCR, western blot analysis and luciferase reporter assays confirmed that ZEB1 was a direct target of miR‑574 in GBM. Additionally, ZEB1 was demonstrated to be upregulated and inversely correlated with miR‑574 expression in clinical GBM tissues. Rescue experiments demonstrated that overexpression of ZEB1 attenuated the inhibitory effects of miR‑574 on the proliferation and invasion of GBM cells. Overall, the results of the present study highlighted the potential tumour inhibitory roles of miR‑574 in GBM, thereby indicating that miR‑574 may be a novel and efficient therapeutic target for the treatment of patients with GBM.

Abstract
Objectives To explore microRNA-574-3p expression in serum of patients with hepatocellular carcinoma and investigate correlations between serum microRNA-574-3p expression and the development and prognosis of hepatocellular carcinoma. Design and methods Serum samples were collected from 70 patients with primary hepatocellular carcinoma, 40 patients with cirrhosis and 45 healthy controls. Serum microRNA-574-3p expression levels were detected by real-time quantitative polymerase chain reaction. The linearity, specificity and reproducibility were evaluated. In addition, the diagnostic value of microRNA-574-3p and its correlations with clinicopathologic features were assessed. Results The relative expression of microRNA-574-3p in hepatocellular carcinoma patients, cirrhosis patients and healthy controls was 2.306 (1.801-3.130), 1.362 (0.994-1.665) and 1.263 (0.765-1.723), respectively, indicating that it was significantly higher in hepatocellular carcinoma patients than that in the other two groups ( U = 439.5, 514.5, both P < 0.0001) and was significantly correlated with hepatitis B virus DNA copies ( U = 383.0, P = 0.018). In hepatitis B virus-positive hepatocellular carcinoma patients, the relative expression of microRNA-574-3p was significantly correlated with hepatitis B virus DNA concentration ( r = 0.348, P = 0.022). Compared with healthy control group, AUCROC of serum microRNA-574-3p in hepatocellular carcinoma group was 0.837 with 95% CI: 0.763-0.910. Combining microRNA-574-3p, AFU and alpha-fetoprotein together, the sensitivity was highest compared with other markers alone or combined. Conclusions The relative expression of serum microRNA-574-3p in hepatocellular carcinoma patients was significantly higher than that in cirrhosis patients and healthy controls, and it may be an important biomarker in the auxiliary diagnosis of hepatocellular carcinoma.

Abstract
microRNAs (miRNAs) play critical roles in cancer development and progression. This study investigated the effects of miR-19 in human osteosarcoma (OS) development. Here, we showed that miR-19 was frequently upregulated in OS tissues and cell lines. Moreover the expression of miR-19 was associated with TNM stage, metastasis, size and poor overall survival. Mechanistically, miR-19 dramatically suppressed OS growth in vitro and in vivo. Bioinformatics analyses predicted that SOCS6 is a potential target gene of miR-19 in OS, which was confirmed by luciferase-reporter assay. We also found that SOCS6 expression was downregulated and negatively correlated with miR-19 expression in OS tissues clinically. Moreover, ectopic SOCS6 could reverse miR-19 induced OS growth. Finally, JAK2/STAT3 signaling pathway involves miR-19/SOCS6-mediated OS progression. Together, our data provide important evidence for miR-19 mediated SOCS6 in OS growth and revealed miR-19/SOCS6/JAK2/STAT3 pathway as a potential therapeutic strategy for OS patients.
