Abstract
Macrophages (Mφ) are long-lived myeloid cells that can polarize towards the proinflammatory M1 or proresolving M2 phenotype to control diverse biological processes such as inflammation, tissue damage, and regeneration. Noncoding RNA are a class of nonprotein-coding transcriptome with numerous interdependent biological roles; however, their functional interaction in the regulation of Mφ polarization and immune responses remain unclear. Here, we show antagonistic relationship between lncRNA (MALAT1) and microRNA (miR-30b) in shaping macrophage polarization and immune functions. MALAT1 expression displays a time-dependent induction during Mφ differentiation and, upon challenge with TLR4 agonist (E. coli LPS). MALAT1 knockdown promoted the expression of M2Mφ markers without affecting M1Mφ markers, suggesting that MALAT1 favors the M1 phenotype by suppressing M2 differentiation. Compared to the control, MALAT1 knockdown resulted in reduced antigen uptake and processing, bacterial phagocytosis, and bactericidal activity, strongly supporting its critical role in regulating innate immune functions in Mφ. Consistent with this, MALAT1 knockdown showed impaired cytokine secretion upon challenge with LPS. Importantly, MALAT1 exhibit an antagonistic expression pattern with all five members of the miR-30 family during M2 Mφ differentiation. Dual-luciferase assays validated a novel sequence on MALAT1 that interacts with miR-30b, a microRNA that promotes the M2 phenotype. Phagocytosis and antigen processing assays unequivocally demonstrated that MALAT1 and miR-30b are functionally antagonistic. Concurrent MALAT1 knockdown and miR-30b overexpression exhibited the most significant attenuation in both assays. In human subjects with periodontal disease and murine model of ligature-induced periodontitis, we observed higher levels of MALAT1, M1Mφ markers and downregulation of miR-30b expression in gingival tissues suggesting a pro-inflammatory function of MALAT1 in vivo. Overall, we unraveled the role of MALAT1 in Mφ polarization and delineated the underlying mechanism of its regulation by involving MALAT-1-driven miR-30b sequestration.

Abstract
BACKGROUND Milk composition is complex and includes numerous components essential for offspring growth and development. In addition to the high abundance of miR-30b microRNA, milk produced by the transgenic mouse model of miR-30b-mammary deregulation displays a significantly altered fatty acid profile. Moreover, wild-type adopted pups fed miR-30b milk present an early growth defect. OBJECTIVE This study aimed to investigate the consequences of miR-30b milk feeding on the duodenal development of wild-type neonates, a prime target of suckled milk, along with comprehensive milk phenotyping. METHODS The duodenums of wild-type pups fed miR-30b milk were extensively characterized at postnatal day (PND)-5, PND-6, and PND-15 using histological, transcriptomic, proteomic, and duodenal permeability analyses and compared with those of pups fed wild-type milk. Milk of miR-30b foster dams collected at mid-lactation was extensively analyzed using proteomic, metabolomic, and lipidomic approaches and hormonal immunoassays. RESULTS At PND-5, wild-type pups fed miR-30b milk showed maturation of their duodenum with 1.5-fold (P < 0.05) and 1.3-fold (P < 0.10) increased expression of Claudin-3 and Claudin-4, respectively, and changes in 8 duodenal proteins (P < 0.10), with an earlier reduction in paracellular and transcellular permeability (183 ng/mL fluorescein sulfonic acid [FSA] and 12 ng/mL horseradish peroxidase [HRP], respectively, compared with 5700 ng/mL FSA and 90 ng/mL HRP in wild-type; P < 0.001). Compared with wild-type milk, miR-30b milk displayed an increase in total lipid (219 g/L compared with 151 g/L; P < 0.05), ceramide (17.6 μM compared with 6.9 μM; P < 0.05), and sphingomyelin concentrations (163.7 μM compared with 76.3 μM; P < 0.05); overexpression of 9 proteins involved in the gut barrier (P < 0.1); and higher insulin and leptin concentrations (1.88 ng/mL and 2.04 ng/mL, respectively, compared with 0.79 ng/mL and 1.06 ng/mL; P < 0.01). CONCLUSIONS miR-30b milk displays significant changes in bioactive components associated with neonatal duodenal integrity and maturation, which could be involved in the earlier intestinal closure phenotype of the wild-type pups associated with a lower growth rate.

Abstract
BACKGROUND Puberty marks the transition from childhood to adulthood and is initiated by activation of a pulsatile GnRH secretion from the hypothalamus. MKRN3 functions as a pre-pubertal break on the GnRH pulse generator and hypothalamic expression and circulating levels of MKRN3 decrease peri-pubertally. In rodents, microRNA miR-30b seems to directly target hypothalamic MKRN3 expression - and in boys, circulating levels of miR-30b-5p increase when puberty is pharmacologically induced. Similarly, miR-200b-3p and miR-155-5p have been suggested to inhibit expression of other proteins potentially involved in the regulation of GnRH secretion. Here we measure circulating levels of these three miRNAs as boys progress through puberty. MATERIALS AND METHODS Forty-six boys from the longitudinal part of the Copenhagen Puberty Study were included. All boys underwent successive clinical examinations including estimation of testis size by palpation. miR-30b-5p, miR-200b-3p, and miR-155-5p were measured in serum by RT-qPCR using a kit sensitive to the phosphorylation status of the miRNAs. Thirty-nine boys had miRNA levels measured in three consecutive samples (pre-, peri-, and post-pubertally) and seven boys had miR-30b-5p levels measured in ten consecutive samples during the pubertal transition. RESULTS When circulating levels of miR-30b-5p in pre- and peri-pubertal samples were compared with post-pubertal levels, we observed a significant increase of 2.3 and 2.2-fold (p-value<6.0×10-4), respectively, and a larger fraction of miR-30b-5p appeared to be phosphorylated post-pubertally indicating an increase in its bioactivity. We also observed a negative correlation between circulating levels of miR-30b-5p and MKRN3. The inter-individual variation in circulating miR-30b levels was substantial and we could not define a clinical threshold for miR-30b-5p suggestive of imminent puberty. Also, miR-155-5p showed significantly increasing levels from the peri- to the post-pubertal stage (p=3.0×10-3), whereas miR-200b-3p did not consistently increase. CONCLUSION Both circulating levels of miR-30b-5p and its bioactivity increase during the pubertal transition in boys supporting its role in the activation of the HPG axis at the onset of physiologically normal puberty.

Abstract
OBJECTIVE Adipose tissue is a major source of circulating microRNAs (miRNAs) that can regulate target genes in distant organs. However, the role of brown adipose tissue (BAT) in diabetic kidney disease (DKD) is still unknown. We studied the original BAT miR-30b targeting two key fibrotic regulators, Runt-related transcription factor 1 (Runx1) and snail family zinc finger 1 (Snail1), to combat DKD. METHODS First, we transplanted healthy BAT from normal mouse donors into diabetic mice (induced by a high-fat diet and streptozotocin injection). In vitro, we observed extracellular vesicles (EVs) secreted from brown adipocytes. AgomiR-30b was directly administered to the BAT of diabetic mice twice weekly for 4 consecutive weeks. Next, the role of Runx1 in DKD was determined by using siRUNX1 or pCMV-RUNX1 in HK-2 cells and in diabetic mice treated with AAV9-U6-shRunx1 or AAV9-EF1a-Runx1. RESULTS BAT transplantation reactivated endogenous BAT activity in diabetic mice, increased circulating miR-30b levels and significantly ameliorated DKD. In TGFβ1-treated HK-2 cells, miR-30b expression was significantly suppressed. miR-30b overexpression markedly decreased fibronectin and downregulated Runx1 and Snail1 expression, while silencing of miR-30b had the opposite effects. Next, Runx1 knockdown and overexpression mimicked the above phenotype of miR-30b mimics and inhibitors, respectively, both in vitro and in vivo. Moreover, Runx1 promoted TGFβ1-induced fibrosis by upregulating the PI3K pathway. CONCLUSION BAT-derived miRNAs might be a promising target for kidney protection in diabetes mellitus.

Abstract
Endoplasmic reticulum stress (ERS) plays an important role in cerebral ischemia-reperfusion injury (CIRI) by regulating apoptosis. Although the role of long non-coding RNA (LncRNA) KCNQ1OT1 in CIRI has been reported, the specific mechanism is still unclear. In this paper, the regulation of ERS by LncRNA KCNQ1OT1 in CIRI and its mechanism were studied. Transient middle cerebral artery occlusion (tMCAO) model was established in SD rats with KCNQ1OT1 intervention. PC12 cells were used to construct the OGD/R cell model. The expressions of LncRNA KCNQ1OT1 and miR-30b were detected by RT-qPCR. TCC staining was used to detect the extent of cerebral ischemia. TUNEL staining was used to detect apoptosis level, and Western blot was used to detect the expressions of ERS and apoptosis-related proteins. The targeted binding of LncRNA KCNQ1OT1, miR-30b, and GRP78 was detected by double luciferase assay. The expressions of LncRNA KCNQ1OT1 and miR-30b were interfered by cell transfection. Cell proliferation was detected by CCK-8. The level of LncRNA KCNQ1OT1 was increased and that of miR-30b was decreased in the blood samples of patients with CIRI. In tMCAO rats with KCNQ1OT1 intervention, the expression of miR-30b was increased, and the ischemic range of brain tissues was decreased. What's more, the level of ERS was decreased, and the apoptosis of brain tissues was decreased. LncRNA KCNQ1OT1 could regulate miR-30b/GRP78 in OGD/R cells in a targeted way. Intervention of KCNQ1OT1 could promote the proliferation of OGD/R cells, inhibiting the level of ERS and cell apoptosis. Further inhibition of miR-30b could reverse the effect of intervention of KCNQ1OT1. LncRNA KCNQ1OT1 regulates ERS to affect CIRI through targeting miR-30b/GRP78.

Abstract
The dental pulp can be affected by thermal, physical, chemical, and bacterial phenomena that stimulate the inflammatory response. The pulp tissue produces an immunological, cellular, and vascular reaction in an attempt to defend itself and resolve the affected tissue. The expression of different microRNAs during pulp inflammation has been previously documented. MicroRNAs (miRNAs) are endogenous small molecules involved in the transcription of genes that regulate the immune system and the inflammatory response. They are present in cellular and physiological functions, as well as in the pathogenesis of human diseases, becoming potential biomarkers for diagnosis, prognosis, monitoring, and safety. Previous studies have evidenced the different roles played by miRNAs in proinflammatory, anti-inflammatory, and immunological phenomena in the dental pulp, highlighting specific key functions of pulp pathology. This systematized review aims to provide an understanding of the role of the different microRNAs detected in the pulp and their effects on the expression of the different target genes that are involved during pulp inflammation.

Abstract
AIMS Calcific aortic valve disease (CAVD) is frequent in the elderly. Telocytes (TCs) are implicated in intercellular communication by releasing extracellular vesicles (EVs). This study investigated the role of TC-EVs in aortic valve calcification. METHODS AND RESULTS TCs were obtained and identified using enzymolysis method and flow cytometry. EVs were isolated from TCs using differential high-speed centrifugation method and identified using transmission electron microscope, western blot, and qNano analysis. The mouse model of CAVD was established. The changes of aortic valve activity-related indicators were analysed by ultrasound, and the expressions of TC markers CD34 and vimentin in mouse valve tissues were detected using RT-qPCR and western blot. The model mice were injected with TC-derived EVs. The expressions of Runx2, osteocalcin, and caspase-3 were detected using RT-qPCR and western blot. The calcification model of valvular interstitial cells (VICs) was established. TC-EVs were co-cultured with calcified VICs, and calcium deposition was detected using alizarin red S staining. miR-30b expression in calcified valvular tissues and cells was detected after EV treatment. miR-30b expression in TCs was knocked down and then EVs were extracted and co-cultured with calcified VICs. The target of miR-30b was predicted through bioinformatics website and verified using dual-luciferase assay. The levels of Wnt/β-catenin pathway-related proteins were detected. ApoE-/- mice fed with a high-fat diet showed decreased aortic valve orifice area, increased aortic transvalvular pressure difference and velocity, reduced left ventricular ejection fraction, decreased CD34 and vimentin, and increased caspase-3, Runx2, and osteocalcin. The levels of apoptosis- and osteogenesis- related proteins were inhibited after EV treatment. TC-EVs reduced calcium deposition and osteogenic proteins in calcified VICs. EVs could be absorbed by VICs. miR-30b expression was promoted in calcified valvular tissues and cells after EV treatment. Knockdown of miR-30b weakened the inhibitory effects of TC-EVs on calcium deposition and osteogenic proteins. miR-30b targeted Runx2. EV treatment inhibited the Wnt/β-catenin pathway, and knockdown of miR-30b in TCs attenuated the inhibitory effect of TC-EVs on the Wnt/β-catenin pathway. CONCLUSION TC-EVs played a protective role in aortic valve calcification via the miR-30b/Runx2/Wnt/β-catenin axis.

Abstract
Chronic exposure of triclosan (TCS) to zebrafish triggers high incidence of fatty liver and hepatitis; however, the underlying molecular mechanisms remain unclear. Herein, we identified miR-30b as a sensitive biomarker to TCS stress, reflecting in that its decreased expression caused metabolic toxicity, abnormal development and behavior, and lipid-metabolism disorder. By microinjecting the inhibitor and mimic experiments, miR-30b was proved to regulate lipid metabolism by its main target gene fto. Over-expression of FTO resulted in fat accumulation, elevation of the TG and TC levels and up-regulation of the PPARγ and CEBPα, as well as decrease of the global m6A level in larvae. On the contrary, the knock-down of FTO using MO caused the anti-lipogenic effect, decrease of the TG and T-CHO levels, and abnormal changes of cebpɑ, acsl5, fasn, ppap2c and pparγ etc. Further fortification tests of cycloleucine and betaine evidenced that the toxic effect was strongly dependent on regulation of the m6A level. The toxicity effects in the treatments of methylated donors and receptors were consistent with the changes in physiological functions of FTO knockdown and overexpression. The effects of cycloleucine on m6A level and lipid metabolism generally consisted with those of FTO, but this was not the case for betaine, reflecting in increased m6A level and lipid accumulation in larval liver. Consequently, we posit that TCS exposure caused zebrafish lipid-metabolism disorder by decreasing miR-30b expression to regulate fto-mediated m6A methylation level. These findings contribute to our deep understanding of the underlying molecular mechanisms regarding contaminant-originating fatty liver and hepatocellular carcinoma, and also have practical significance in pollution warning and target therapy for related diseases.

Abstract
Long non-coding RNA (lncRNA) X-inactive specific transcript (XIST) plays an essential role in the development and progress of nasopharyngeal carcinoma (NPC). MicroRNA-30b (miR-30b) has been confirmed to play an inhibitory role in various types of cancer. The molecular mechanisms underlying the lncRNA XIST-mediated regulation of the metastasis of NPC cells by miR-30b is not clear. qPCR and western blot analysis were used to detect the expression of XIST, miR-30b, and reversion inducing cysteine rich protein with kazal motifs (RECK) in NPC tissues and cell lines. The detection of luciferase reporter gene confirmed the relationship between lncRNA XIST, miR-30b and RECK. CCK-8 and Transwell assays were performed in order to detect the proliferation, migration and invasion of the NPC cells. The results of qPCR and western blotting indicated that the expression levels of lncRNA XIST and RECK were higher in the NPC tissues and cell lines than that of the control group, while the expression of miR-30b was lower. Knockdown of lncRNA XIST significantly inhibited cell proliferation, migration and invasion in the NPC cell lines. In addition, lncRNA XIST was found to negatively regulate the expression of miR-30b, resulting in the upregulation of RECK. Overexpression of RECK was found to reverse the inhibitory effect of lncRNA XIST knockdown or miR-30b on NPC cell metastasis. Our results showed that cell migration and invasion were inhibited by knockdown of lncRNA XIST, suggesting that the lncRNA XIST/miR-30b/RECK axis is involved in the development of NPC.

Abstract
Spinal cord injury (SCI) induces both motor and sensory dysfunctions. We wondered whether miR-30b could promote primary sensory neuron (PSN) axon growth in inhibitory microenvironment. The neurite growth was promoted by miR-30b agomir and inhibited by antagomir. MiR-30b targeted and degraded sema3A mRNA. MiR-30b regulated the formation of sema3A-NRP-1-PlexinA1 complex via targeting sema3A. The neurite length was induced by the miR-30b agomir, and the application of sema3A protein could reverse the effect of agomir. GTP-RhoA and ROCK expression were down-regulated by miR-30b. Neurite outgrowth that inhibited by sema3A and the miR-30b antagomir was increased by Y-27632. Agomir promoted neurite growth in NogoA inhibitory conditions, which indicated miR-30b could both enhance neuronal intrinsic regenerative ability and promote neurite growth against inhibitory microenvironment via Sema3A/NRP-1/PlexinA1/RhoA/ROCK axis. The agomir could also regulate Sema3A/NRP-1/PlexinA1/RhoA/ROCK axis in vivo and restore spinal cord sensory conductive function. In conclusion, miR-30b could be a novel target for sensation recovery after SCI.

Abstract
Long non-coding RNAs (lncRNAs) have been increasingly found to fulfill key functions in neurodegenerative diseases. This study aimed to probe the function of lncRNA MALAT1 in neuronal recovery in Alzheimer's disease (AD). Aβ25-35 was used to induce AD in a rat model and neuronal injury in PC12 and C6 cells. Aberrantly expressed lncRNAs/microRNAs (miRNAs) in AD rats were screened out by microarray analyses. Altered expression of MALAT1, miR-30b and CNR1 was performed to explore their roles in neuronal recovery in rat and cell models. Consequently, LncRNA MALAT1 and CNR1 were poorly expressed while miR-30b was highly expressed in Aβ25-35-induced rat models and cells. Overexpression of MALAT1 or CNR1 reduced neuronal injury in rat hippocampus. It increased viability and decreased apoptosis in injured PC12 and C6 cells, and decreased the secretion of pro-inflammatory factor IL-6 and TNF-α but increased IL-10 production. However, overexpression of miR-30b reversed these trends. MALAT1 could served as a sponge for mR-30b to up-regulate CNR1 expression. The phosphorylation of PI3K and AKT was stimulated when MALAT1 or CNR1 was overexpressed. To sum up, we found MALAT1 could promote neuronal recovery following AD through the miR-30b/CNR1 network and the PI3K/AKT signaling activation.

Abstract
Purpose Prevailing evidences have demonstrated that circular RNAs (circRNAs) are closely associated with various stages of carcinogenesis. However, very few studies have delineated the specific mechanism of association between circRNAs and osteosarcoma (OS). It offers a novel insight that circRNAs can be explored as a potential therapeutic strategy for OS. Materials and Methods In this study, circTUBGCP3 was chosen from the existing reported circRNA microarray data obtained from OS cell lines and normal bone cells. Subsequently, qRT-PCR was performed to evaluate the expression level of circTUBGCP3 in OS samples and cell lines. Functional assays were conducted to estimate the impact of circTUBGCP3 on human OS cells proliferation, vitality, survivability, and migration. Western blot, luciferase reporter and in vivo tumorigenesis assays were performed to analyze the signaling pathways underlying the interaction of circTUBGCP3, miR-30b, and Vimentin. Results The data indicate that circTUBGCP3 may act as a sponge of miR-30b that further alters the expression of Vimentin, and promotes the proliferation and metastatic properties of OS cells. Conclusion circTUBGCP3 serves as a tumor promoter in tumorigenesis by increasing the possibilities of OS initiation and proliferation.

Abstract
OBJECTIVE To explore the function of miR-30b in pathogenesis of Parkinson's disease (PD) and its underlying molecular mechanism. MATERIALS AND METHODS We used 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPP(+)) as a tool for constructing the PD cell model, using miR-30b mimics or inhibitors to manipulate miR-30b level for an experimental model of acquisition. The cell viability of SH-SY5Y was detected by CCK, and luciferase was used to screen the binding of target genes. The protein levels of SNCA were measured by Western blot. Then, we investigate the changes in pro- and anti-apoptotic markers with or without miR-30b treatment. RESULTS There was a significant low expression of MiR-30b in MPP(+)-induced cells. SH-SY5Y cell viability was rescued by MiR-30b overexpression. Luciferase experiments showed that MiR-30b may bind to the 3'-UTR side of SNCA and inhibited its expression. By Western blot, the SNCA level was markedly decreased by miR-30b. miR-30b attenuated the upregulation of Bax and the depletion of Bcl-2 induced by MPP(+).

Abstract
BACKGROUND Ovarian cancer is one of the most common and malignant cancers, partly due to its late diagnosis and high recurrence. Chemotherapy resistance has been linked to poor prognosis and is believed to be linked to the cancer stem cell (CSC) pool. Therefore, elucidating the molecular mechanisms mediating therapy resistance is essential to finding new targets for therapy-resistant tumors. METHODS shRNA depletion of MYPT1 in ovarian cancer cell lines, miRNA overexpression, RT-qPCR analysis, patient tumor samples, cell line- and tumorsphere-derived xenografts, in vitro and in vivo treatments, analysis of data from ovarian tumors in public transcriptomic patient databases and in-house patient cohorts. RESULTS We show that MYPT1 (PPP1R12A), encoding myosin phosphatase target subunit 1, is downregulated in ovarian tumors, leading to reduced survival and increased tumorigenesis, as well as resistance to platinum-based therapy. Similarly, overexpression of miR-30b targeting MYPT1 results in enhanced CSC-like properties in ovarian tumor cells and is connected to the activation of the Hippo pathway. Inhibition of the Hippo pathway transcriptional co-activator YAP suppresses the resistance to platinum-based therapy induced by either low MYPT1 expression or miR-30b overexpression, both in vitro and in vivo. CONCLUSIONS Our work provides a functional link between the resistance to chemotherapy in ovarian tumors and the increase in the CSC pool that results from the activation of the Hippo pathway target genes upon MYPT1 downregulation. Combination therapy with cisplatin and YAP inhibitors suppresses MYPT1-induced resistance, demonstrating the possibility of using this treatment in patients with low MYPT1 expression, who are likely to be resistant to platinum-based therapy.

Abstract
Preeclampsia (PE) may induce gestational failure threatening a significant number of pregnant women. Dysfunctional placental trophoblast cells have an important impact on PE progression. microRNAs (miRNAs) have been reported to participate in PE progression, whereas the mechanism that underlies miR-30b involved in PE progression and function of placental trophoblast cells remains poorly understood. Cell viability was investigated by cell counting kit-8 (CCK-8) assay. Cell apoptosis was detected by flow cytometry using Annexin V-FITC/propidium iodide (PI) staining. Cell invasion was analyzed by trans-well assay. The expression of miR-30b was measured by quantitative real-time polymerase chain reaction (qRT-PCR). The abundance of matrix-remodeling associated 5 (MXRA5) protein was detected by western blots (WB). The interaction between miR-30b and MXRA5 was investigated by bioinformatics analysis and luciferase activity assay. The effect of miR-30b and MXRA5 on mitogen-activated protein kinases (MAPK) pathway and invasion was evaluated by WB. Then we found miR-30b was highly expressed in PE and its overexpression inhibited cell viability and invasion while enhanced apoptosis in JEG-3 and HTR8/SVneo cells. Moreover, MXRA5 was targeted by miR-30b and MXRA5 restoration attenuated the effect of miR-30b on cell processes in HTR8/SVneo cells. Besides, both of miR-30b and MXRA5 were associated with MAPK pathway in HTR8/SVneo cells. Our data suggested miR-30b might contribute to PE through inhibiting cell viability, invasion while inducing apoptosis of placental trophoblast cells via MAPK pathway by targeting MXRA5. These indicated that miR-30b might be a novel biomarker for PE treatment.

Abstract
Lung cancer, especially non-small cell lung cancer (NSCLC), is the leading cause of cancer-related mortality in the world. Both microRNAs and epidermal growth factor receptor (EGFR) are important factors in NSCLC. In our study, the expression of miR-30b in 47 tumor tissues and paired normal tissues of NSCLC were detected by RT-PCR, and we found that miR-30b was down-regulated in NSCLC tumor tissues and was associated with TNM stage, differentiation, and lymph node metastases. Then we investigated the ability of miR-30b to regulate EGFR in several NSCLC cell lines, and found that miR-30b inhibited proliferation, migration and invasion, induced apoptosis and enhanced sensitivity of the NSCLC cells to EGFR tyrosine kinase inhibitors (EGFR-TKIs) by targeting EGFR and repressing EGFR signaling pathways. Overall, these results indicate that miR-30b may be a potential therapeutic target in NSCLC patients.

Abstract
Microenvironment components profoundly influence the propensity of cancer metastasis through regulating key molecules controlling metastasis. Lysyl oxidase (LOX) contributes to extracellular matrix (ECM) remodeling, and finally promoting bone metastasis in breast cancer. Kynurenine (Kyn), a microenvironment component, is capable of regulating the biological behaviors of cancer cells, such as promoting node metastasis in vivo. However, it is still unclear whether Kyn controls the generation of LOX. In the current study, a significant increase of migration in the Kyn (30, 50, 100, 200, and 500 μM) group was detected compared with that in the control group in 95D cells in vitro. Subsequently, we demonstrated that 50 μM Kyn not only substantially upregulated the mRNA and secreted levels of LOX rather than cytoplasmic LOX, but also markedly reduced the level of miR-30b at the same time. Furthermore, the direct interaction between LOX mRNA and miR-30b was also confirmed by dual-luciferase assay system. Most importantly, not only was Kyn-induced increase of LOX mRNA significantly attenuated on miR-30b mimics treatment, but also Kyn-mediated the upregulation of the mRNA, and secreted levels of LOX were distinctly strengthened on miR-30b inhibitor treatment. These results suggest that miR-30b is involved in Kyn-mediated LOX expression.

Abstract
During lactation, mammary epithelial cells secrete fat in the form of milk fat globules that originate from intracellular lipid droplets. These droplets may form de novo from the endoplasmic reticulum or be derived from existing lipid droplets; they then either grow because enzymes of triacylglycerol synthesis relocate from the reticulum to their surface, or due to fusion and fission with other droplets. The overexpression of miR-30b-5p in the developing mouse mammary gland impairs lactation, which includes an increase in lipid droplet size. This study was performed to understand the origin of this defect affecting lipid droplets observed in transgenic mice. Electron microscopy analyses revealed a fragmented and discontinued tubular network of endoplasmic reticulum in the mammary epithelial cells of transgenic mice. The milk fatty acid composition was modified, with lower levels of medium-chain saturated fatty acids and a proportional increase in long-chain monounsaturated fatty acids in transgenic versus wild-type mice. Further, investigations of microRNA targets revealed a significant downregulation of ATLASTIN 2 (a GTPase described as playing a key role in lipid droplet formation) due to miR-30b-5p overexpression. Our results suggest that the increase in lipid droplet size observed in the mammary epithelial cells of transgenic mice might result from changes to lipid droplet formation and secretion because of direct modifications to Atl2 expression and indirect changes to endoplasmic reticulum morphology resulting from the overexpression of miR-30b-5p.

Abstract
Background MicroRNAs (miRNAs) play an essential role in the initiation, progression and metastasis of breast cancer. It has been confirmed that miR-30b is involved in various cancers. However, the specific involvement of miR-30b on breast cancer metastasis remains unknown. In the current study, we aimed to investigate the role of miR-30b in the progression and metastasis of breast cancer in vitro. Methods We up-regulated the expression of miR-30b in breast cancer cell lines SKBR3 and MDA-MB-231 by transfecting pCMV-miR-30b vector. CCK8, colony formation, Transwell, and flow cytometry assays were used to examine cell proliferation, migration, invasion and apoptosis, respectively. A dual-luciferase reporter assay was performed to identify the relationship between miR-30b and the target gene. Western blot assay was used to detect related proteins. Results Our data showed that the overexpression of miR-30b significantly inhibited proliferation, migration and invasion abilities in SKBR3 and MDA-MB-231 cells. Meanwhile, overexpression of miR-30b induced cell apoptosis for both SKBR3 and MDA-MB-231 cells by regulating the expression of apoptosis-related proteins (Bcl-2, Bax, active Caspase-3, and Caspase-9). Moreover, miR-30b inhibited the activation of the PI3K/Akt signaling pathway by decreasing the phosphorylation levels of Akt and mTOR. Furthermore, we determined that miR-30b could down-regulate the expression of Derlin-1 in a post-transcriptional manner by employing the dual-luciferase reporter and western blot assays. Further analysis demonstrated that depletion of Derlin-1 inhibited Akt phosphorylation, and Derlin-1 could restore the effect of miR-30b on Akt. In addition, the CCK8 assay showed that Derlin-1 could partly reverse the inhibition of cell proliferation of SKBR3 and MDA-MB-231 cells mediated by miR-30b. Conclusions Our data demonstrated that miR-30b suppresses the progression and metastasis of breast cancer via inhibition of the PI3K/Akt signaling pathway by targeting Derlin-1 in vitro. This suggests that miR-30b might be a novel potent target for breast cancer therapy.

Abstract
Osteosarcoma is a prevalent primary malignant tumor and long non-coding RNAs (lncRNAs) have been validated to modulate the osteosarcoma tumorigenesis. In present study, our research team investigates the role of a novel identified lncRNA DICER1-AS1 on the tumor progression and autophagy. Results showed that lncRNA DICER1-AS1 was up-regulated in osteosarcoma cells using microarray analysis and RT-PCR. Cellular functional experiments revealed that DICER1-AS1 knockdown suppressed the proliferation, migration, invasion and autophagy of osteosarcoma cells in vitro. Besides, DICER1-AS1 knockdown inhibited the protein expression levels of ATG5, LC3-II and Beclin 1, suggesting the inhibition on the autophagy of osteosarcoma cells. Moreover, miR-30b was verified to target 3'-UTR of DICER1-AS1 and ATG5 using bioinformatics tools and luciferase reporter assay or RNA-immunoprecipitation (RIP). Western blot showed that ATG5 protein expression was decreased in DICER1-AS1 knockdown and miR-30b mimics transfected cells, while increased in miR-30b inhibitor transfected cells, presenting a negative correlation with miR-30b and a positive correlation with DICER1-AS1. Finally, xenograft assay in vivo indicated that DICER1-AS1 knockdown inhibited the osteosarcoma tumor growth and protein expression level of ATG5. In summary, all the results conclude that DICER1-AS1 regulates the proliferation, invasion and autophagy of osteosarcoma via miR-30b/ATG5 axis, providing a novel insight for osteosarcoma tumorigenesis.

Abstract
Snail-mediated epithelial-mesenchymal transition (EMT) process plays a fundamental role in facilitating pancreatic ductal adenocarcinoma (PDAC) stemness and metastasis. In the present study, we revealed that microRNA-30 (miR-30) members, especially miR-30b, were remarkably downregulated in triple-positive (CD24+, CD44+, EpCAM+) pancreatic cancer stem cells (PCSCs). In addition, we revealed that miR-30b suppressed EMT process in PCSCs. Overexpression of miR-30b led to reduced expression of mesenchymal marker N-cadherin and the upregulation of epithelial marker E-cadherin. Moreover, both of TargetScan and PicTar algorithms predicted that miR-30b directly targeted Snail 3'UTR. Luciferase reporter assay showed that miR-30b could specifically reduce the translational activity of Snail wild-type 3'UTR, but not its mutant form. In line with these results, transwell assay demonstrated that overexpression of miR-30b mimic impaired migratory and invasive capacities of PCSCs. Furthermore, miR-30b overexpression suppresses in vivo tumorigenic potential of PDACs. Finally, a negative correlation between the expression of miR-30b and Snail was uncovered. Low level of miR-30b and high Snail expression both predict dismal prognosis in PDAC patients. Taken together, these findings implicate that miR-30b may suppress PCSC phenotype and PDAC metastasis through posttranscriptionally suppressing Snail expression, highlighting that miR-30b may serve as a therapeutic agent in the treatment of PDAC.

Abstract
Mesenchymal stem cells (MSCs) have been found to benefit patients with a variety of ischemic diseases via promoting angiogenesis. It is also well established that exosomes secreted from MSCs deliver bioactive molecules, including microRNAs (miRs) to recipient cells. Therefore, we hypothesized that exosomes secreted from MSCs deliver miRs into endothelial cells and mediate angiogenesis. The pro-angiogenic stimulatory capacity of exosomes was investigated using tube-like structure formation and spheroid-based sprouting of human umbilical vein endothelial cells (HUVECs), and in vivo Matrigel plug assay. The secretion of pro-angiogenic miRs (pro-angiomiRs) from MSCs into culture medium and transfer of the miRs to HUVECs were confirmed using real-time quantitative PCR. Supplementation of the exosome secretion blocker GW4869 (10 μM) reduced the pro-angiomiRs in the MSC-derived conditioned medium (CdMMSC). Addition of exosomes isolated from CdMMSC could directly 1) promote HUVEC tube-like structure formation in vitro; 2) mobilize endothelial cells into Matrigel plug subcutaneously transplanted into mice; and 3) increase blood flow inside Matrigel plug. Fluorescence tracking showed that the exosomes were internalized rapidly by HUVECs causing an upregulated expression of pro-angiomiRs in HUVECs. Loss-and-gain function of the pro-angiomiRs (e.g., miR-30b) in MSCs significantly altered the pro-angiogenic properties of these MSC-derived exosomes, which could be associated with the regulation of their targets in HUVECs. These results suggest that exosomal transfer of pro-angiogenic miRs plays an important role in MSC mediated angiogenesis and stem cell-to-endothelial cell communication.

Abstract
Numerous studies have shown that feeding rodents n-3 polyunsaturated fatty acids attenuates adiposity. Moreover, meta-analyses of human dietary intervention studies indicate that fish oil (eicosapentaenoic and docosahexaenoic acid) supplementation might reduce waist circumference. A recent line of research suggests that browning of white adipose depots and activation of uncoupled respiration in brown fat contributes to these effects. This mini-review summarizes the observations in rodents, highlights several mechanisms that might explain these observations and discusses the translational potential. Given the available in vivo evidence and the ability of human adipocytes to aquire a beige phenotype in response to eicosapentaenoic acid incubation, future studies should test the hypothesis that fish oil activates thermogenic brown and beige adipose tissue in humans.

Abstract
The present study aimed to investigate whether miR-30b plays a pivotal role in the progression of esophageal squamous cell carcinoma (ESCC) as well as to elucidate its possible regulatory mechanism. The expression levels of miR-30b in the ESCC tissues and cells were determined. The TE-1 cells were transfected with the miR-30b mimic, the mimic control, the miR-30b inhibitor, the inhibitor control, the pCDNA3.1-Chromobox 3 (pCDNA3.1-CBX3) and/or the blank vector, while the TE-2 cells were transfected with the miR-30b mimic and/or the mimic control. Cell proliferation, cell apoptosis, and cell migration of the different transfected groups were evaluated. The luciferase reporter assay was performed to detect the relationship between miR-30b, and CBX3. Furthermore, the relationship between miR-30b, CBX3, and the JAK2/STAT3 signaling pathway was explored. Significant downregulation of miR-30b was observed in the ESCC tissues and cells, while CBX3 was upregulated in the ESCC tissues and cells. The inhibition of miR-30b promoted cell proliferation, inhibited cell apoptosis, and enhanced cell migration in ESCC, which was similar to the effects of CBX3 overexpression. In fact, CBX3 was confirmed to be a direct target of miR-30b. The overexpression of miR-30b decreased the expression levels of p-JAK2/JAK2 and p-STAT3/JAK3 significantly, which was obviously reversed after the simultaneous overexpression of CBX3. Our results revealed that the downregulation of miR-30b may increase cell proliferation, inhibit cell apoptosis, and promote cell migration in ESCC by targeting CBX3 and activating the JAK2/STAT3 signaling pathway. Thus, miR-30b may serve as a useful marker for predicting the progression of ESCC.

Abstract
The present study aimed to investigate the mechanisms underlying microRNA (miRNA)-mediated regulation of chondrogenic differentiation. Mouse embryo-derived stem cells C3H10T1/2 were cultured and chondrogenic differentiation was induced using transforming growth factor-β3 (TGF-β3). In addition, miRNA expression profiles were detected via miRNA array analysis, and quantitative polymerase chain reaction was performed to verify the differentially expressed miRNAs. Furthermore, bioinformatics software was used to predict the putative targets and the prediction was validated by dual-luciferase reporter assays and western blot analysis. In addition, cell proliferation and glycosaminoglycans were measured by a direct cell count method and alcian blue staining, respectively. Compared with the control group, 86 miRNAs were identified as differentially expressed in TGF-β3-induced cells and the expression levels of 28 miRNAs were increased while the remaining 58 miRNAs exhibited a decline in expression. Amongst the differentially expressed miRNAs, miR-30b expression was observed to have significantly decreased during chondrogenic differentiation. SOX9 is a target gene of miR-30b, and miR-30b inhibits SOX9 expression during chondrogenic differentiation. Furthermore, the alcian blue staining results demonstrated that miR-30b inhibited early chondrogenic differentiation. However, the data of the present study indicated that miR-30b had no influence on C3H10T1/2 cell line proliferation. In conclusion, miR-30b is a key negative regulator of TGF-β3-induced C3H10T1/2 cell chondrogenic differentiation, which functions by directly targeting SOX9.

Abstract
BACKGROUND/AIMS Autophagy is an evolutionarily conserved mechanism that affects the survival and functions of vascular smooth muscle cells (VSMCs). We explored the role of microRNAs (miRNAs) in regulating autophagy in VSMCs exposed to high phosphorus (Pi) levels. METHODS VSMCs were isolated from the thoracic aorta of rats and were cultured primarily. Real-time PCR was used to measure the mRNA expression of indicated genes. Western blotting was performed to detect the protein expression of autophagy-related markers. RESULTS We found that treatment with high Pi levels (1 and 3 mM) activated LC3II expression and promoted autophagic flux in VSMCs. Conversely, treatment with an autophagy inhibitor decreased LC3II expression. Pi stimulation dysregulated the expression of several miRNAs such as miR-18a, miR-21, miR-23a, miR-30b, and miR-31a. However, miR-30b overexpression decreased Pi-induced expression of autophagy-related marker genes such as BECN1, ATG5, and LC3b, whereas miR-30b downregulation increased Pi-induced expression of these genes. In addition, we found that miR-30b directly targeted BECN1. CONCLUSIONS These data suggest that miR-30b plays an important role in the regulation of high Pi level-induced autophagy in VSMCs by targeting BECN1.

Abstract
Nav1.3 is a tetrodotoxin-sensitive isoform among voltage-gated sodium channels that are closely associated with neuropathic pain. It can be up-regulated following nerve injury, but its biological function remains uncertain. MicroRNAs (miRNAs) are endogenous non-coding RNAs that can regulate post-transcriptional gene expression by binding with their target mRNAs. Using Target Scan software, we discovered that SCN3A is the major target of miR-30b, and we then determined whether miR-30b regulated the expression of Nav1.3 by transfecting miR-30b agomir through the stimulation of TNF-α or by transfecting miR-30b antagomir in primary dorsal root ganglion (DRG) neurons. The spinal nerve ligation (SNL) model was used to determine the contribution of miR-30b to neuropathic pain, to evaluate changes in Nav1.3 mRNA and protein expression, and to understand the sensitivity of rats to mechanical and thermal stimuli. Our results showed that miR-30b agomir transfection down-regulated Nav1.3 mRNA stimulated with TNF-α in primary DRG neurons. Moreover, miR-30b overexpression significantly attenuated neuropathic pain induced by SNL, with decreases in the expression of Nav1.3 mRNA and protein both in DRG neurons and spinal cord. Activation of Nav1.3 caused by miR-30b antagomir was identified. These data suggest that miR-30b is involved in the development of neuropathic pain, probably by regulating the expression of Nav1.3, and might be a novel therapeutic target for neuropathic pain. Perspective: This study is the first to explore the important role of miR-30b and Nav1.3 in spinal nerve ligation-induced neuropathic pain, and our evidence may provide new insight for improving therapeutic approaches to pain.

Abstract
Emerging evidence has shown that microRNAs (miRNAs) play important roles in tumor development and progression. In particular, miR-30b is thought to be closely related to the migration, invasion, proliferation, communication, and drug resistance of tumor cells. However, the potential value of miR-30b in human esophageal cancer (EC) remains unclear. In this study, we investigated the biological functions of miR-30b and its potential role in EC. The results indicated that the expression levels of miR-30b were decreased in EC tissues and were correlated with invasion classification (P < 0.01), lymph node metastasis (P < 0.01), and pathological stage (P < 0.05). Log-rank tests demonstrated that low expression of miR-30bwas strongly correlated with poor overall survival in patients with EC (P < 0.05). Moreover, overexpression of miR-30b markedly inhibited the growth, migration, and invasion of ECA109 and TE-1 cells by directly downregulating homeobox A1 (HOXA1). When HOXA1 was reintroduced into miR-30b-transfected ECA109 or TE-1 cells, the inhibitory effects of miR-30b on EC cell growth, migration, and invasion were markedly reversed. In conclusion, our findings demonstrated that miR-30b could inhibit tumor cell growth, migration, and invasion by directly targeting HOXA1 in EC cells.

Abstract
AIM: To explore the role and potential mechanism of miR-30b regulation of autophagy in hepatic ischemia-reperfusion injury (IRI).
METHODS: An animal model of hepatic IRI was generated in C57BL/6 mice. For in vitro studies, AML12 cells were immersed in mineral oil for 1 h and then cultured in complete Dulbecco’s Modified Eagle’s Medium (DMEM)/F12 to simulate IRI. Mice and cells were transfected with miR-30b agomir/mimics or antagomir/inhibitor to examine the effect of miR-30b on autophagy to promote hepatic IRI. The expression of miR-30b was measured by real-time polymerase chain reaction. Apoptotic cells were detected by terminal uridine nick-end labeling (TUNEL) staining, and cell viability was detected by methylthiazole tetrazolium assay. The expression of light chain 3, autophagy-related gene (Atg)12, Atg5, P62, and caspase-3 were detected by western blotting analysis.
RESULTS: miR-30b levels were significantly downregulated after hepatic IRI, and the numbers of autophagosomes were increased in response to IRI both in vivo and in vitro. These findings demonstrate that low levels of miR-30b could promote hepatic IRI. Furthermore, we found that miR-30b interacted with Atg12-Atg5 conjugate by binding to Atg12. Overexpression of miR-30b diminished Atg12 and Atg12-Atg5 conjugate levels, which promoted autophagy in response to IR. In contrast, downregulation of miR-30b was associated with increased Atg12-Atg5 conjugate levels and increased autophagy.
CONCLUSION: miR-30b inhibited autophagy to alleviate hepatic ischemia-reperfusion injury via decreasing the Atg12-Atg5 conjugate.

Abstract
Long non-coding RNAs (lncRNAs) had been proved to be pivotal regulators in carcinogenesis. On the basis of competitive endogenous RNAs (ceRNAs) system, lncRNAs significantly expanded their regulating networks. In our research, we aimed to figure out the exact role of lncRNA HNF1A-AS1 in the pathogenesis of hepatocellular carcinoma (HCC), in a ceRNA-dependent way. First, we revealed: HNF1A-AS1 was frequently overexpressed in HCC tissues and cell lines and its relative high expression was closely related to larger tumor size, multiple tumor lesions, poor differentiation and advanced TNM stage. Then we found: HNF1A-AS1 functioned as an oncogene in tumor growth and apoptosis through sponging tumor-suppressive hsa-miR-30b-5p (miR-30b) and de-repressing Bcl-2. Further experiments identified: HNF1A-AS1-miR-30b axis significantly promoted autophagy under starvation and ATG5 was first proved to be a target of miR-30b. In summary, we identified HNF1A-AS1-miR-30b axis as a key regulator in hepatocarcinogenesis, which may be promising biomarkers and therapeutic targets in the future.

Abstract
BACKGROUND Non-small cell lung cancer (NSCLC) is the largest histological subgroup of lung cancer and has increased in prevalence in China over the past 5 years. The 5-year survival rate has remained at 15-20 %, with a median survival of 8-12 months. The tumorigenesis and progression of NSCLC is orchestrated by numerous oncogene and anti-oncogene mutations and insights into microRNA function have increased our understanding of the process. Here, we investigated the effects of miR-30b on NSCLC cell invasion and migration and explored the underlying molecular mechanisms involved. METHODS Quantitative reverse transcription PCR, wound healing assay, trans-well assays, western blotting and dual luciferase assays were performed to investigate the molecular mechanisms of miR-30b in NSCLC cells. RESULTS MiR-30b was down-regulated and Cthrc1 up-regulated in NSCLC tissues. Both were associated with tumor differentiation, TNM stage and lymph node metastases. Up-regulation of miR-30b restricted A549 and Calu-3 cell invasion and migration. Additionally, the expression of Cthrc1, matrix metalloproteinase-9 and matrix metalloproteinase-2 was reduced, while metallopeptidase inhibitor-1 expression increased. Bioinformatics analysis identified Cthrc1 as a target of miR-30b and western blotting and luciferase reporter assays confirmed that miR-30b regulates Cthrc1 by directly binding to its 3'UTR. Transfection of Cthrc1 without the 3'UTR restored the miR-30b inhibiting cell invasion. Up-regulation of miR-30b or down-regulation of Cthrc1 had potential significance in the invasion and metastasis of NSCLC. CONCLUSIONS MiR-30b was down-regulated and Cthrc1 up-regulated in NSCLC tissues. Both of them were related to tumor differentiation, TNM stage and lymph node metastases. MiR-30b affected NSCLC cells invasion and migration by regulating Cthrc1.

Abstract
AIM To elucidate the potential biological role of miR-30b in gastric cancer and investigate the underlying molecular mechanisms of miR-30b to inhibit metastasis of gastric cancer cells. METHODS The expression of miR-30b was detected in gastric cancer cell lines and samples by reverse transcription-polymerase chain reaction. CCK-8 assays were conducted to explore the impact of miR-30b overexpression on the proliferation of gastric cancer cells. Flow cytometry was used to examine the effect of miR-30b on the apoptosis. Transwell test was used for the migration and invasion assays. Luciferase reporter assays and Western blot were employed to validate regulation of putative target of miR-30b. RESULTS The results showed that miR-30b was downregulated in gastric cancer tissues and cancer cell lines and functioned as a tumor suppressor. Overexpression of miR-30b promoted cell apoptosis, and suppressed proliferation, migration and invasion of the gastric cancer cell lines AGS and MGC803. Bioinformatic analysis identified the 3'-untranslated region of eukaryotic translation initiation factor 5A2 (EIF5A2) as a putative binding site of miR-30b. Luciferase reporter assays and Western blot analysis confirmed the EIF5A2 gene as a target of miR-30b. Moreover, expression levels of the EIF5A2 targets E-cadherin and Vimentin were altered following transfection of miR-30b mimics. CONCLUSION Our findings describe a link between miR-30b and EIF5A2, which plays an important role in mediating epithelial-mesenchymal transition.

Abstract
Homocysteine (Hcy) is an independent risk factor for a variety of cardiovascular diseases, such as coronary heart disease, hypertension, stroke, etc. There is a close relationship between the vascular endothelial cell apoptosis and these diseases. Recent studies have shown homocysteine can induce apoptosis in endothelial cells, which may be an important mechanism for the development of theses cardiovascular diseases. Although there are several reports about how the Hcy induces apoptosis in endothelial cells, the exact mechanism is not fully understood. MicroRNAs are small, non-coding RNA. Previous studies have shown that there is a close relationship between several microRNAs and cell apoptosis. However, there are no studies about the role of microRNAs in Hcy-induced apoptosis in endothelial cells so far. In this study, we constructed the model of homocysteine-induced apoptosis in human coronary artery endothelial cells (HCAECs) and found miR-30b was significantly down-regulated by 1 mmol/L Hcy. In addition, overexpression of miR-30b can improve the Hcy-induced apoptosis in HCAECs by downregulating caspase-3 expression. Therefore, miR-30b may play an important role in Hcy-induced apoptosis in endothelial cells.

Abstract
Semaphorin3A (Sema3A) is a major inhibitory factor of optic nerve (ON) regeneration post-injury. Many microRNAs (miRNAs) are expressed specifically in the mammalian brain and retina and are dynamically regulated during development, suggesting that this group of miRNAs may be associated with neural development. We found that microRNA-30b (miR-30b) bound to the three prime untranslated region (3' UTR) of Sema3A and inhibited the expression of Sema3A mRNA. The mRNA expression level of miR-30b and the protein expression levels of Sema3A, Neuropilin1 (NRP1), PlexinA1 (PlexA1), phosphorylated p38MAPK (p-p38MAPK), and active caspase-3 were all upregulated in retinas from rats with a damaged ON relative to those with an intact ON. Transfection of cultured retinal ganglion cells (RGCs) with an miR-30b mimic led to decreased levels of Sema3A, NRP1, PlexA1, p-p38MAPK, and active caspase-3 protein expression, as well as axon elongation and reduced levels of apoptosis. These findings provide evidence that miR-30b inhibits Sema3A expression. Decreased Sema3A expression promotes axon outgrowth in RGCs due to reduced levels of Sema3A binding to NRP1 and PlexA1 and simultaneously reduces apoptosis by inhibiting the p38MAPK and caspase-3 pathways. Our findings provide the first evidence that miR-30b-mediated Sema3A downregulation may serve as a new strategy for the clinical treatment of ON injury.

Abstract
Colorectal cancer (CRC) is the third most common cancer in the USA. MicroRNAs play important roles in the pathogenesis of CRC. In this study, we investigated the role of miR-30b in CRC and found that its expression was significantly lower in CRC tissues than that in normal tissues. We showed that a low expression level of miR-30b was closely related to poor differentiation, advanced TNM stage and poor prognosis of CRC. Further experiments showed that over-expression of miR-30b suppressed CRC cell proliferation in vitro and tumour growth in vivo. Specifically, miR-30b promoted G1 arrest and induced apoptosis. Moreover, KRAS, PIK3CD and BCL2 were identified as direct and functional targets of miR-30b. MiR-30b directly targeted the 3'-untranslated regions of their mRNAs and repressed their expression. This study revealed functional and mechanistic links between miRNA-30b and oncogene KRAS, PIK3CD and BCL2 in the pathogenesis of CRC. MiR-30b not only plays important roles in the regulation of cell proliferation and tumour growth in CRC, but is also a potential prognostic marker or therapeutic target for CRC. Restoration of miR-30b expression may represent a promising therapeutic approach for targeting malignant CRC.

Abstract
OBJECTIVE Although several miRNAs have been shown to regulate autoimmune pathogenesis by affecting lymphocyte function, the roles of miRNAs in the pathogenesis of SSc remain unclear. Therefore the purpose of this study was to identify miRNAs that play a role in the pathogenesis of SSc by quantitative PCR screening of serum miRNAs. METHODS Ninety-five miRNAs that were predicted to target SSc-related genes [IL-4, TGF-β, CTGF, PDGF-B, PDGF receptor (PDGFR) α/β and COL1A2) by in silico analyses were selected. The expression of these miRNAs in sera of SSc patients and healthy controls was measured by quantitative PCR. Involvement of miR-30b, which was most strongly down-regulated in SSc patients, in the regulation of PDGFR-β expression was examined by transfection experiments and 3'-untranslated region (3'-UTR) target luciferase assays. The expression of miR-30b in skin was evaluated in a bleomycin-induced dermal fibrosis model in mice and in SSc patients. RESULTS Nineteen of 95 miRNAs were significantly decreased in the sera of SSc patients. Among them, miR-30b was most strongly down-regulated in SSc patients (P = 0.00006) and the levels of miR-30b were inversely correlated with modified Rodnan skin scores. Transfection of a miR-30b mimic repressed PDGFR-β expression in dermal fibroblasts and the activity of a luciferase reporter containing 3'-UTR of PDGFR-β. Moreover, the expression of miR-30b was down-regulated in bleomycin-treated sclerotic skin and in affected skin in SSc patients. CONCLUSION Down-regulation of miR-30b might be involved in the pathogenesis of SSc.
