Abstract
Traumatic spinal cord injury (TSCI) is a prevalent central nervous system condition that imposes a significant burden on both families and society, affecting more than 2 million people worldwide. Recently, there has been increasing interest in bone marrow mesenchymal stem cell (BMSC) transplantation as a promising treatment for spinal cord injury (SCI) due to their accessibility and low immunogenicity. However, the mere transplantation of BMSCs has limited capacity to directly participate in the repair of host spinal cord nerve function. MiR-28-5p, identified as a key differentially expressed miRNA in spinal cord ischemia-reperfusion injury, exhibits differential expression and regulation in various neurological diseases. Nevertheless, its involvement in this process and its specific regulatory mechanisms in SCI remain unclear. Therefore, this study aimed to investigate the potential mechanisms through which miR-28-5p promotes the neuronal differentiation of BMSCs both in vivo and in vitro. Our results indicate that miR-28-5p may directly target Notch1, thereby facilitating the neuronal differentiation of BMSCs in vitro. Furthermore, the transplantation of lentivirus-mediated miR-28-5p-overexpressed BMSCs into SCI rats effectively improved footprint tests and Basso, Beattie, and Bresnahan (BBB) scores, ameliorated histological morphology (hematoxylin-eosin [HE] and Nissl staining), promoted axonal regeneration (MAP2 and growth-associated protein 43 [GAP43]), and facilitated axonal remyelination (myelin basic protein [MBP]). These findings may suggest that miR-28-5p-modified BMSCs could serve as a therapeutic target to enhance the behavioral and neurological recovery of SCI rats.

Abstract
Follicular atresia occurs in every stage of ovarian development, which is relevant to female fertility. In the past decade, increasing studies have confirmed that miRNAs, a class of short non-coding RNAs, play an important role in follicular atresia by post-transcription regulation of their target genes. However, the function of miRNAs on follicular atresia initiation is unknown. In the present study, high-throughput small RNA sequencing was performed to analyze differential miRNA expression profiles between healthy (HF) follicles and early atretic (EAF) follicles. A total of 237 conserved miRNA were detected, and the miR-143 is the highest expressed in follicles. Meanwhile, we also found wide sequence variations (isomiRs) in porcine ovarian miRNA, including in 5'un-translation region, core seed sequences and 3'untranslation region. Furthermore, we identified 22 differentially expressed miRNAs in EAF groups compared to HF group, of which 3 miRNAs were upregulated, as well as 19 miRNAs were downregulated, and then the RT-PCR was performed to validate these profiles. The target genes of these differentially expressed miRNAs were predicted by using miRwalk, miRDB, and Targetscan database, respectively. Moreover, the gene ontology and KEGG pathway enrichment established that the regulating functions and signaling pathways of these miRNAs contribute to follicular atresia initiation and cell fate. In conclusion, this study provides new insights into the changes of miRNAs in early atretic follicles to demonstrate their molecular regulation in ovarian follicular atretic initiation.

Abstract
Our previous studies have shown that highly phosphorylated casein phosphopeptides (residues 1-25) P5 could efficiently bind calcium and promote intestinal calcium absorption, and enhanced bone development in rats. The purpose of this study was to investigate the effect of the phosphorylation structure in P5 on the proliferation, differentiation, and mineralization of osteoblasts (MC3T3-E1) and its mechanism. P5 was obtained by high-performance liquid chromatography (HPLC) and non-phosphorylated peptide P5-0 was obtained by chemical synthesis. Compared with the control group, the proliferation rate of MC3T3-E1 cells treated by P5 was 1.10 times that of P5-0 at 200 μg mL-1. P5 caused the cell cycle retention of MC3T3-E1 cells in the G2/M phase, while P5-0 had no significant difference in the G2/M phase. MC3T3-E1 cells incubated with P5 showed stronger alkaline phosphatase (ALP) activity than with P5-0, suggesting a tendency to promote cellular differentiation. Compared to the P5-0 treatment group, the P5 treatment group at concentrations of 10 μg mL-1 showed significant differences in the mineralization rates (p < 0.05). P5 significantly upregulated the expressions of Runx2, ALP, ColIα1, and OCN compared with the control group (p < 0.05). In addition, in silico molecular docking showed that the binding force of the P5-EGFR complex was stronger than that of the P5-0-EGFR complex, which was significantly related to the phosphorylation structure in P5 and might be an important reason for osteoblast proliferation. In conclusion, the phosphorylation structure and amino acid composition in P5 stimulated the osteogenic activity of MC3T3-E1 cells, and could be expected to be a functional food for the prevention of osteoporosis.

Abstract
BACKGROUND Hypertension is a severe public health risk factor worldwide. Elevated angiotensin II (Ang II) produced by the renin-angiotensin-aldosterone system can lead to hypertension and its complications. METHOD In this study, we addressed the cardiac-injury effects of Ang II and investigated the signaling mechanism induced by Ang II. Both H9c2 cardiomyoblast cells and neonatal rat cardiomyocytes were exposed to Ang II to observe hypertension-related cardiac apoptosis. RESULTS The results of western blotting revealed that Ang II significantly attenuated the IGF1R-PI3K-AKT pathway via the Ang II-AT1 receptor axis and phosphatase and tensin homolog expression. Furthermore, real-time PCR showed that Ang II also activated miR-320-3p transcription to repress the PI3K-Akt pathway. In the heart tissue of spontaneously hypertensive rats, activation of the IGF1R survival pathway was also reduced compared with that in Wistar-Kyoto rats, especially in aged spontaneously hypertensive rats. CONCLUSION Hence, we speculate that the Ang II-AT1 receptor axis induces both phosphatase and tensin homolog and miR-320-3p expression to downregulate the IGF1R-PI3K-AKT survival pathway and cause cell apoptosis in the heart.

Abstract
Bone marrow-derived mesenchymal stem cells (BMSCs) have therapeutic potential for spinal cord injury (SCI). We have shown that insulin-like growth factor 1 (IGF-1) enhances the cellular proliferation and survivability of BMSCs-derived neural progenitor cells (NPCs) by downregulating miR-22-3p. However, the functional application of BMSCs-derived NPCs has not been investigated fully. In this study, we demonstrate that knockdown of endogenous miR-22-3p in BMSCs-derived NPCs upregulates Akt1 expression, leading to enhanced cellular proliferation. RNASeq analysis reveals 3,513 differentially expressed genes in NPCs. The upregulated genes in NPCs enrich the gene ontology term associated with nervous system development. Terminally differentiated NPCs generate cells with neuronal-like morphology and phenotypes. Transplantation of NPCs in the SCI rat model results in better recovery in locomotor and sensory functions 4 weeks after transplantation. Altogether, the result of this study demonstrate that NPCs derived with IGF-1 supplementation could be differentiated into functional neural lineage cells and are optimal for stem cell therapy in SCI.

JOURNAL OF ETHNOPHARMACOLOGY 2021; 281:114559. [PMID: 34461189 DOI: 10.1016/j.jep.2021.114559] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/07/2021] [Revised: 08/17/2021] [Accepted: 08/21/2021] [Indexed: 06/13/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Naoluoxintong (NLXT) is a traditional Chinese Medicine (TCM) prescription that is clinically used in the treatment of ischemic stroke (IS). However, its therapeutic mechanism remains unclear. AIM OF THE STUDY To obtain the mechanism of NLXT by observing the protective effects of NLXT on the NogoA/RhoA/Rock pathway in a rat model of IS by regulating DNA methylation. MATERIALS AND METHODS Rats were divided into five groups using a random number table: normal group, model group, NLXT group, blocker group I (NLXT + SGI-1027) and blocker group II (NLXT + Y27632). The right middle cerebral artery occlusion-reperfusion (MCAO/R) rat model was made, and the regional cerebral blood flow (rCBF) of each group was detected using laser Doppler. The methylation levels of CpG sites of neurite outgrowth inhibitor protein-A (Nogo-A), Nogo receptor (NgR), ras homolog gene family member A (RhoA) and rho-associated coiled-coil protein kinase 2 (ROCK2) genes in rat brain tissue were detected using the bisulfite method. Reverse transcription-polymerase chain reaction (RT-PCR) was used to detect NogoA, RhoA, NgR1, NgR2 and ROCK2 mRNA expression in rat brain tissue. NogoA, RhoA, NgR1, NgR2 and ROCK2 proteins were detected using immunoblotting in rat brain tissue. RESULTS After the modeling of middle cerebral artery occlusion (MCAO), neurological deficit test was made to ensure the success of the modeling. At each time point after surgery, the rCBF of the other groups decreased compared with the normal group (P < 0.01 or P < 0.05). Meanwhile, the rCBF increased in blocker group I as well as blocker group II after 3 days (P < 0.05). There were differences in the DNA methylation sites of NogoA, RhoA, NgR and ROCK2 genes between the model group and the NLXT group (P < 0.05). Compared with the normal group, NogoA, NgR1, NgR2, RhoA and ROCK2 gene expression in the model group increased observably (P < 0.01). In comparison with the model group, NogoA and NgR1 gene expression in the blocker group II was prominently observed on the 1st day. NogoA, NgR1, NgR2, RhoA and ROCK2 gene expression remarkably reduced (P < 0.01) on the 3rd and 7th days. Compared with the normal group, NogoA, RhoA, NgR1, NgR2 and ROCK2 protein expression in the model group increased observably (P < 0.01). In comparison with the model group, NogoA, RhoA, NgR1, NgR2 and ROCK2 protein expression in the other groups declined prominently (P < 0.01). CONCLUSION NLXT can reduce the DNA methylation level of NogoA pathway after IS, thus inhibit the expression of NogoA/RhoA/ROCK pathway from producing anti-cerebral ischemia pharmacological effect.

Abstract
Mesenchymal stem cells (MSCs) have become a promising tool for neurorestorative therapy of neurodegenerative diseases (NDDs), which are mainly characterized by the progressive and irreversible loss of neuronal structure and function in the central or peripheral nervous system. Recently, studies have reported that genetic manipulation mediated by noncoding RNAs (ncRNAs) can increase survival and neural regeneration of transplanted MSCs, offering a new strategy for clinical translation. In this review, we summarize the potential role and regulatory mechanism of two major types of ncRNAs, including microRNAs (miRNAs) and long noncoding RNAs (lncRNAs), during the neurogenesis of MSCs with gene expression profile analyses. We also overview the realization of MSC-based therapy mediated by ncRNAs in the treatment of spinal cord injury, stroke, Alzheimer's disease and peripheral nerve injury. It is expected that ncRNAs will become promising therapeutic targets for NDD on stem cells, while the underlying mechanisms require further exploration.

Abstract
INTRODUCTION Mesenchymal stem cells (MSCs) isolated from bone marrow have different developmental origins, including neural crest. MSCs can differentiate into neural progenitor-like cells (NPCs) under the influence of bFGF and EGF. NPCs can terminally differentiate into neurons that express beta-III-tubulin and elicit action potential. The main aim of the study was to identify key genetic markers involved in differentiation of MSCs into NPCs through transcriptomic analysis. METHOD Total RNA was isolated from MSCs and MSCs-derived NPCs followed by cDNA library construction for transcriptomic analysis. Sample libraries that passed the quality and quantity assessments were subjected to high throughput mRNA sequencing using NextSeq®500. Differential gene expression analysis was performed using the DESeq2 R package with MSC samples being a reference group. The expression of eight differentially regulated genes was counter validated using real-time PCR. RESULTS In total, of the 3,252 differentially regulated genes between MSCs and NPCs with two or more folds, 1,771 were upregulated genes, whereas 1,481 were downregulated in NPCs. Amongst these differential genes, 104 transcription factors were upregulated, and 45 were downregulated in NPCs. Neurogenesis related genes were upregulated in NPCs and the main non-redundant gene ontology (GO) terms enriched in NPCs were the autonomic nervous system, cell surface receptor signalling pathways), extracellular structure organisation, and programmed cell death. The main non-redundant GO terms enriched in MSCs included cytoskeleton organisation cytoskeleton structural constituent, mitotic cell cycle), and the mitotic cell cycle process Gene set enrichment analysis also confirmed cell cycle regulated pathways as well as Biocarta integrin pathway were upregulated in MSCs. Transcription factors enrichment analysis by ChEA3 revealed Foxs1 and HEYL, amongst the top five transcription factors, inhibits and enhances, respectively, the NPCs differentiation of MSCs. CONCLUSIONS The vast differences in the transcriptomic profiles between NPCs and MSCs revealed a set of markers that can identify the differentiation stage of NPCs as well as provide new targets to enhance MSCs differentiation into NPCs.

Abstract
Mesenchymal stem cells (MSCs) represent a promising source of cell-based therapies for treatment of a wide variety of injuries and diseases. Their tropism and migration to the damaged sites, which are elicited by cytokines secreted from tissues around pathology, are the prerequisite for tissue repair and regeneration. Better understanding of the elicited-migration of MSCs and discovering conditions that elevate their migration ability, will help to increase their homing to pathologies and improve therapeutic efficacy. It is increasingly recognized that microRNAs are important regulators of cell migration. Here we summarize current understanding of the microRNA-regulated migration of MSCs.

Abstract
Many studies supported that bone marrow mesenchymal stem cells (BM-MSCs) can differentiate into neural cells, but few researchers detected mature and function of nerve cells, especially in vivo study. Some researchers even suggested that BM-MSCs transplantation would not be able to differentiate into functional neural cells. To figure out the dispute, this study examined bone marrow-derived sphere-like cells, harvested via neural stem cell suspension culture, then identified as bone marrow-derived neural progenitor cells (BM-NPCs) by finding the expression of neural progenitor cells genes and proteins, neural progenitor cells characteristic and nerve cell differentiation induced through both methods. Moreover, BM-NPCs transplantation showed long-term survival and improved the ethological and histological indexes of brain injury rats, demonstrating functional nervous cells differentiated from BM-NPCs. These in vitro and in vivo results confirmed BM-NPCs differentiating into mature and functional nerve cells. This study provided valuable experimental data for BM-NPCs, suggesting a potential alternative treatment of central nervous injury disease.

Abstract
OBJECTIVE To observe the effects of Naoluo Xintong on the expression of β-tubulin Ⅲ and glial fibrillary acidic protein (GFAP) and the proliferation and differentiation of murine neural stem cells (NSCs) in vitro. METHODS An immortalized murine NSC line was divided into model control (MC) group, 10% Naoluo Xintong drug-containing serum group (NLXT group), and 10% Naoluoxintong drug-containing serum with inhibitor Y27632 group (Y-27632 group) with corresponding treatments. The activity of the NSCs was detected after the treatments using MTT assay, and the migration of the cells was observed with Transwell assay. The expressions of β-tubulin Ⅲ, GFAP and MAP-2 proteins in the cells were detected with immunoblotting, and the expressions of DCX, NEUN, and β-tubulin Ⅲ were also detected with immunofluorescence assay. RESULTS Compared with that in MC group, the number of migrated cells in NLXT group and Y-27632 group increased significantly at 1 day and 3 days after induction (P < 0.05). The survival rate and the number of migrated cells in NLXT group and Y-27632 group increased significantly on day 7 (P < 0.01). Compared with those in MC group, the expressions of β-tubulin Ⅲ, MAP2 and GFAP protein in NLXT group and Y-27632 group were significantly increased on days 3 (P < 0.01) and 7 (P < 0.05). The numbers of β-tubulinⅢ/ GFAP, BrdU/DCX, and BrdU/NEUN labeled cells in the NLXT group and Y-27632 group were significantly greater than those in the MC group. CONCLUSIONS Naoluo Xintong promotes the proliferation and differentiation of murine NSCs in vitro by regulating the expressions of β-tubulinⅢ/GFAP.

Abstract
Objective To investigate the involvement of microRNAs (miRNAs) in the pathogenesis of
obstructive sleep apnea-hypopnea syndrome (OSAHS). Methods In this study, we investigated miRNA profiles in the upper airway (UA)
skeletal muscles of four patients with OSAHS and four matched controls using
the miRCURY miRNA array. In another cohort of 12 OSAHS cases and 7 controls,
the mRNA expression levels of interleukin (IL)-6 and Lin-28 homolog A
(Lin28A), targets of the downregulated let-7 family members, were measured
by real-time quantitative-PCR. The potential targets of the miRNAs were
predicted by miRNA target prediction databases miRanda, Microcosm, and
Targetscan. Results The array identified 370 differentially expressed miRNAs, of which 181 were
upregulated and 189 were downregulated in OSAHS patients (based on a
fold-change >2.0 and p < 0.05). Upregulation of IL-6
and Lin28A was validated by quantitative reverse transcription PCR. The 612
targets predicted by all three algorithms were subjected to gene ontology
(GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analyses.
The results revealed perturbations in signaling pathways and cellular
functions. Conclusion This study demonstrated profoundly altered miRNA expression profiles in upper
airway muscular tissues of patients with OSAHS, which might contribute to
the formation and development of OSAHS.

Abstract
Insulin-like growth factor binding protein 4 (IGFBP-4) was reported to trigger cellular senescence and reduce cell growth of bone marrow mesenchymal stem cells (BMSCs), but its contribution to neurogenic differentiation of BMSCs remains unknown. In the present study, BMSCs were isolated from the femur and tibia of young rats to investigate effects of IGFBP-4 on BMSC proliferation and growth of neurospheres derived from BMSCs. Bone marrow mesenchymal stem cell proliferation was assessed using CCK-8 after treatment with IGFBP-4 or blockers of IGF-IR and β-catenin. Phosphorylation levels of Akt, Erk, and p38 in BMSCs were analysed by Western blotting. Bone marrow mesenchymal stem cells were induced into neural lineages in NeuroCult medium; the number and the size of BMSC-derived neurospheres were counted after treatment with IGFBP-4 or the blockers. It was shown that addition of IGFBP-4 inhibited BMSC proliferation and immunodepletion of IGFBP-4 increased the proliferation. The blockade of IGF-IR with AG1024 increased BMSC proliferation and reversed IGFBP-4-induced proliferation inhibition; however, blocking of β-catenin with FH535 did not. p-Erk was significantly decreased in IGFBP-4-treated BMSCs. IGFBP-4 promoted the growth of neurospheres derived from BMSCs, as manifested by the increases in the number and the size of the derived neurospheres. Both AG1024 and FH535 inhibited the formation of NeuroCult-induced neurospheres, but FH535 significantly inhibited the growth of neurospheres in NeuroCult medium with EGF, bFGF, and IGFBP-4. The data suggested that IGFBP-4 inhibits BMSC proliferation through IGF-IR pathway and promotes growth of BMSC-derived neurospheres via stabilizing β-catenin.

Abstract
Widespread death of transplanted mesenchymal stem cells (MSCs) hampers the development of stem cell therapy for Alzheimer disease (AD). Cell pre-conditioning might help cope with this challenge. We tested whether let-7f-5p-modified MSCs could prolong the survival of MSCs after transplantation. When exposed to Aβ25−35in vitro, MSCs showed significant early apoptosis with decrease in the let-7f-5p levels and increased caspase-3 expression. Upregulating microRNA let-7f-5p in MSCs alleviated Aβ25−35-induced apoptosis by decreasing the caspase-3 levels. After computerized analysis and the luciferase reporter assay, we identified that caspases-3 was the target gene of let-7f-5p. In vivo, hematoxylin and eosin staining confirmed the success of MSCs transplantation into the lateral ventricles, and the let-7f-5p upregulation group showed the lowest apoptotic rate of MSCs detected by TUNEL immunohistochemistry analysis and immunofluorescence. Similarly, bioluminescent imaging showed that let-7f-5p upregulation moderately prolonged the retention of MSCs in brain. In summary, we identified the anti-apoptotic role of let-7f-5p in Aβ25−35-induced cytotoxicity, as well as the protective effect of let-7f-5p on survival of grafted MSCs by targeting caspase-3 in AD models. These findings show a promising approach of microRNA-modified MSCs transplantation as a therapy for neurodegenerative diseases.

Abstract
The putative tumor suppressor microRNA let-7c is extensively associated with the biological properties of cancer cells. However, the potential involvement of let-7c in the differentiation of mesenchymal stem cells has not been fully explored. In this study, we investigated the influence of hsa-let-7c (let-7c) on the proliferation and differentiation of human dental pulp-derived mesenchymal stem cells (DPMSCs) treated with insulin-like growth factor 1 (IGF-1) via flow cytometry, CCK-8 assays, alizarin red staining, real-time RT-PCR, and western blotting. In general, the proliferative capabilities and cell viability of DPMSCs were not significantly affected by the overexpression or deletion of let-7c. However, overexpression of let-7c significantly inhibited the expression of IGF-1 receptor (IGF-1R) and downregulated the osteo/odontogenic differentiation of DPMSCs, as indicated by decreased levels of several osteo/odontogenic markers (osteocalcin, osterix, runt-related transcription factor 2, dentin sialophosphoprotein, dentin sialoprotein, alkaline phosphatase, type 1 collagen, and dentin matrix protein 1) in IGF-1-treated DPMSCs. Inversely, deletion of let-7c resulted in increased IGF-1R levels and enhanced osteo/odontogenic differentiation. Furthermore, the ERK, JNK, and P38 MAPK pathways were significantly inhibited following the overexpression of let-7c in DPMSCs. Deletion of let-7c promoted the activation of the JNK and P38 MAPK pathways. Our cumulative findings indicate that Let-7c can inhibit the osteo/odontogenic differentiation of IGF-1-treated DPMSCs by targeting IGF-1R via the JNK/P38 MAPK signaling pathways.

Abstract
AIMS As a glucagon-like peptide-1 receptor agonist, liraglutide could effectively increase insulin secretion from pancreatic β-cells and suppress glucagon secretion from pancreatic α-cells in the treatment of hyperglycemia in type 2 diabetes patients. However, the mechanisms for the different regulation of pancreatic α-cells and β-cells are still unclear. In this study, we mainly explored the different effects of liraglutide on mouse pancreatic α-cell line and β-cell line in vitro. MAIN METHODS Herein, mouse pancreatic α-cell line, α-TC1-6, and mouse pancreatic β-cell line, β-TC-tet, were used to analyze the biological effects of liraglutide in different concentrations. Cell proliferation, cell apoptosis and cell secretion ability were detected in different groups. Besides, the level of miR-375 and cAMP-PKA signal pathway were further evaluated using qPCR and western blot. KEY FINDINGS The results indicated that liraglutide could increase the level of miR-375 and cell apoptosis in pancreatic α-cells through inhibiting the cAMP-PKA signal pathway, but activate cAMP-PKA signal pathway in pancreatic β-cells, and further lead to the down-regulation of miR-375 and improve cell viability. Therefore, the treatment with liraglutide could down-regulate the glucagon secretion ability of α-TC1-6 cells, and the insulin secretion ability of β-TC-tet cells was enhanced with the liraglutide treatment in a dose-dependent manner. SIGNIFICANCE In conclusion, we mainly found that liraglutide could regulate the viability of pancreatic α-cells and pancreatic β-cells through inhibiting and activating cAMP-PKA signal pathway respectively. The better understanding of the mechanism could help us to develop more novel therapy methods for diabetes in the future.

Abstract
Background Coliform mastitis is a symptom of postpartum dysgalactia syndrome (PDS), a multifactorial infectious disease of sows. Our previous study showed gene expression profile change after bacterial challenge of porcine mammary epithelial cells (PMECs). These mRNA expression changes may be regulated through microRNAs (miRNAs) which play critical roles in biological processes. Therefore, miRNA expression profile was investigated in PMECs. Results PMECs were isolated from three lactating sows and challenged with heat-inactivated potential mastitis-causing pathogen Escherichia coli (E. coli) for 3 h and 24 h, in vitro. At 3 h post-challenge with E. coli, target gene prediction identified a critical role of miRNAs in regulation of host immune responses and homeostasis of PMECs mediated by affecting pathways including cytokine binding (miR-202, miR-3277, miR-4903); IL-10/PPAR signaling (miR-3277, miR-4317, miR-548); and NF-ĸB/TNFR2 signaling (miR-202, miR-2262, miR-885-3p). Target genes of miRNAs in PMECs at 24 h were significantly enriched in pathways associated with interferon signaling (miR-210, miR-23a, miR-1736) and protein ubiquitination (miR-125, miR-128, miR-1280). Conclusions This study provides first large-scale miRNA expression profiles and their predicted target genes in PMECs after contact with a potential mastitis-causing E. coli strain. Both, highly conserved miRNAs known from other species as well as novel miRNAs were identified in PMECs, representing candidate predictive biomarkers for PDS. Time-dependent pathogen clearance suggests an important role of PMECs in inflammatory response of the first cellular barrier of the porcine mammary gland.

Abstract
BACKGROUND Propofol is a widely used intravenous anesthetic that is well-known for its protective effect in various human and animal disease models. However, the effects of propofol on neurogenesis, especially on the development of neural stem cells (NSCs), remains unknown. Related microRNAs may act as important regulators in this process. METHODS Published Gene Expression Omnibus (GEO) DataSets related to propofol were selected and re-analyzed to screen neural development-related genes and predict microRNA (miRNA) expression using bioinformatic methods. Screening of the genes and miRNAs was then validated by qRT-PCR analysis of propofol-treated primary embryonic NSCs. RESULTS Four differentially expressed mRNAs were identified in the screen and 19 miRNAs were predicted based on a published GEO DataSet. Two of four mRNAs and four of 19 predicted miRNAs were validated by qRT-PCR analysis of propofol-treated NSCs. Rno-miR-19a (Rno, Rattus Norvegicus) and rno-miR-137, and their target gene EGR2, as well as rno-miR-19b-2 and rno-miR-214 and their target gene ARC were found to be closely related to neural developmental processes, including proliferation, differentiation, and maturation of NSCs. CONCLUSION Propofol influences miRNA expression; however, further studies are required to elucidate the mechanism underlying the effects of propofol on the four miRNAs and their target genes identified in this study. In particular, the influence of propofol on the entire development process of NSCs remains to be clarified.

Abstract
Periodontitis is a chronic inflammatory disease which is caused by bacterial infection and leads to the destruction of periodontal tissues and resorption of alveolar bone. Thus, special attention should be paid to the mechanism under lipopolysaccharide (LPS)-induced periodontitis because LPS is the major cause of periodontitis. However, to date, miRNA expression in the LPS-induced periodontitis has not been well characterized. In this study, we investigated miRNA expression patterns in LPS-treated periodontal ligament cells (PDLCs). Through miRNA array and differential analysis, 22 up-regulated miRNAs and 28 down-regulated miRNAs in LPS-treated PDLCs were identified. Seven randomly selected up-regulated (miR-21-5p, 498, 548a-5p) and down-regulated (miR-495-3p, 539-5p, 34c-3p and 7a-2-3p) miRNAs were examined by qRT-PCR, and the results proved the accuracy of the miRNA array. Moreover, targets of these deregulated miRNAs were analysed using the miRWalk database. Database for Annotation, Visualization and Integration Discovery software were performed to analyse the Gene Ontology and Kyoto Encyclopaedia of Genes and Genomes pathway of differential expression miRNAs, and the results shown that Toll-like receptor signalling pathway, cAMP signalling pathway, transforming growth factor-beta signalling pathway, mitogen-activated protein kinase (MAPK) signalling pathway and other pathways were involved in the molecular mechanisms underlying LPS-induced periodontitis. In conclusion, this study provides clues for enhancing our understanding of the mechanisms and roles of miRNAs as key regulators of LPS-induced periodontitis.

Abstract
Recently there has been growing interest in the differentiation of mesenchymal stem cells (MSCs) into neural lineages. Research suggests that MSCs can be differentiated into neural progenitor-like cells (NPCs) under the specific influence of paracrine factors particularly epidermal growth factor (EGF) and basic fibroblast growth factor (bFGF). Our recent research has found that the addition of insulin-like growth factor 1 (IGF-1) with the combination of the EGF and bFGF could significantly improve the growth and survivability of MSC-derived NPCs. To unravel the molecular mechanism of the improved differentiation we compared the microRNA expression profiles of the differentiation under various combinations of growth factors. MSCs were differentiated into neural lineage in 3 groups; Group A (EGF + bFGF), Group B (EGF + bFGF + IGF-1), and Group C (without growth factor). Regulated microRNAs during the early differentiation were identified by detailed microRNA profiling using Affymetrix GeneChip version 2.0 at three time intervals (day 1, day 3 and day 5). The data were deposited in the Gene Expression Omnibus, series GSE60060.
