Background: Atherosclerosis (AS) induced cardiology disease is largely associated with morbidity and mortality. The dysfunction of vascular smooth muscle cells (VSMCs) is considered to contribute to the etiology of AS. However, the mechanism underlying VSMCs dysfunction remains largely unclear. Our study aimed to explore novel molecules mediating VSMCs function. Methods: Bioinformatical analysis was applied to identify the key miRNAs that was aberrantly expressed in AS mouse and potentially targeted TFPI2. The AS-like cell model was generated by treating VSMCs with ox-LDL. The expression level of miR-513a-5p and TFPI2 in VSMCs and the serum of AS patients was evaluated by RT-qPCR, and the expression level of TFPI2 and PCNA was measured by western blot. The cell viability and migration capacity of VSMCs were determined by CCK-8 and wound healing assay, respectively. The target relationship between miR-513a-5p and TFPI2 was validated by dual-luciferase assay. Results: MiR-513a-5p was highly expressed while TFPI2 presented a low expression in AS patient serum. Treatment with 100 μg/mL ox-LDL overtly facilitated the cell viability and migration of VSMCs, also promoted miR-513a-5p expression while limit the expression of TFPI2. Moreover, silencing miR-513a-5p inhibited the cell viability, migration and the expression of proliferative marker in ox-LDL treated VSMCs, while inhibition of TFPI2 enhanced that. It was further found that miR-513a-5p could target TFPI2 and silencing miR-513a-5p compromised the aggresive effect of TFPI2 inhibition on the viability and migration ox-LDL treated VSMCs. Conclusion: miR-513a-5p could contribute to the dysfunction of VSMCs in AS through targeting and inhibiting TFPI2.

Background: Differentially expressed lncRNAs have been reported to be involved in keratinocyte proliferation and migration, and participate in the development of psoriasis. Potassium voltage-gated channel subfamily Q member 1 overlapping transcript 1 (KCNQ1OT1) was implicated in the pathogenesis of various diseases, including cancer, sepsis, diabetic cardiomyopathy, and atherosclerosis. The influence of KCNQ1OT1 on proliferation and migration of psoriatic keratinocytes was unfolded in this study. Methods: Human keratinocyte cell line (HaCaT) was incubated with TNF-α to establish in vitro cell model of psoriasis. Cell viability and migration were assessed by MTT and wound healing, respectively. Target miRNA of KCNQ1OT1 was identified by luciferase activity and RNA immunoprecipitation (RIP) assays. Results: KCNQ1OT1 was up-regulated in TNF-α-induced HaCaT, and knockdown of KCNQ1OT1 reduced cell viability and suppressed migration of TNF-α-induced HaCaT. KCNQ1OT1 bind to miR-183-3p and negatively regulated expression of miR-183-3p. Over-expression of GAB1 (growth factor receptor binding 2-associated binding protein 1) counteracted with the suppressive effects of KCNQ1OT1 silence on cell viability and migration of TNF-α-induced HaCaT. Conclusion: Silence of KCNQ1OT1 suppressed proliferation and migration of TNF-α-induced HaCaT through regulation of miR-183-3p/GAB1, providing potential strategy for psoriasis.

This current research was performed to investigate the role of typhae pollen polysaccharides (TPP) in hypoxia-treated PC12 cell which was an in vitro cell model of cerebral ischemia. Hypoxia-treated cells were treated with TPP for 12 h. Cell viability and apoptosis were detected by 3-(4,5-dimethylthiazol-2-yl)-2 5-diphenyl-2H-tetrazolium bromide (MTT) assay and flow cytometry, respectively. Cell apoptotic proteins and PI3K/AKT and Ras/Raf/MEK/ERK signal pathway–associated proteins were also examined by western blot. Furthermore, abnormal expression of miR-34a and silent information regulator 1 (SIRT1) was achieved by transfection. Besides, the expression of miR-34a and SIRT1 was examined by quantitative real-time polymerase chain reaction (qRT-PCR). The expression of SIRT1 was detected by qRT-PCR and western blot. The relationship between miR-34a and SIRT1 was verified by luciferase assay. We found that TPP enhanced cell viability and inhibited apoptosis in hypoxia-treated PC12 cells. Moreover, TPP increased the accumulated levels of Bcl-2 while decreased expression of Bax, cleaved Caspase-3, and cleaved PARP. TPP downregulated miR-34a expression while induced by hypoxia. Further results showed that miR-34a overexpression reversed the results led by TPP in cell viability, apoptosis, and its related proteins. In addition, SIRT1 was upregulated by TPP and was verified to be a target of miR-34a. Silence of SIRT1 led to the opposite results led by TPP. In the end, TPP activated PI3K/AKT and Ras/Raf/MEK/ERK signal pathways. In conclusion, TPP plays important roles in regulating cell viability and apoptosis in hypoxia-treated PC12 cells via modulating miR-34a/SIRT1, as well as activating PI3K/AKT and Ras/Raf/MEK/ERK signal pathways.

AbstractPurposeS100A6 protein (calcyclin), a small calcium-binding protein of the S100 family, is often upregulated in various types of cancers, including hepatocellular carcinoma (HCC). The aim of this study was to illustrate the molecular mechanism of S100A6 in regulating the proliferation and migration of HCC cells.MethodsThe expressions of S100A6 in human HCC and adjacent non-tumor liver specimens were detected using immunoblotting and quantitative PCR (qPCR). The recombinant glutathione S-transferase (GST)-tagged human S100A6 protein was purified and identified. After treatment with S100A6, the proliferation of HepG2 cells was detected by the MTT and colony formation assay, and the migration of HepG2 cells was investigated by the transwell migration assay; the protein levels of cyclin D1 (CCND1), E-cadherin, and vimentin were also tested by immunoblotting. The effect of S100A6 on p21 and nuclear factor-κB pathway was verified by performing the dual luciferase assay. Then, the expression of p21 and its transcription activator, p53, was examined using immunoblotting and qPCR, the ubiquitination of which was investigated through co-immunoprecipitation.ResultsIt was found that the level of S100A6 was higher in the HCC tissues than in the adjacent non-tumor liver specimens. Exogenous overexpression of S100A6 promoted the proliferation and migration of HepG2 cells. S100A6 was observed to regulate p21 mRNA and protein expression levels and decrease p53 protein expression level, not mRNA level, by promoting the ubiquitination of p53 via the proteasome-dependent degradation pathway.ConclusionOur study indicated that S100A6 overexpression could promote the proliferation and migration of HCC cells by enhancing p53 ubiquitin-dependent proteasome degradation, ultimately regulating the p21 expression level.

Abstract Background We have previously found that β-elemene could inhibit the viability of airway granulation fibroblasts and prevent airway hyperplastic stenosis. This study aimed to elucidate the underlying mechanism and protective efficacy of β-elemene in vitro and in vivo. Methods Microarray and bioinformatic analysis were used to identify altered pathways related to cell viability in a β-elemene-treated primary cell model and to construct a β-elemene-altered ceRNA network modulating the target pathway. Loss of function and gain of function approaches were performed to examine the role of the ceRNA axis in β-elemene's regulation of the target pathway and cell viability. Additionally, in a β-elemene-treated rabbit model of airway stenosis, endoscopic and histological examinations were used to evaluate its therapeutic efficacy and further verify its mechanism of action. Results The hyperactive ILK/Akt pathway and dysregulated LncRNA-MIR143HG, which acted as a miR-1275 ceRNA to modulate ILK expression, were suppressed in β-elemene-treated airway granulation fibroblasts; β-elemene suppressed the ILK/Akt pathway via the MIR143HG/miR-1275/ILK axis. Additionally, the cell cycle and apoptotic phenotypes of granulation fibroblasts were altered, consistent with ILK/Akt pathway activity. In vivo application of β-elemene attenuated airway granulation hyperplasia and alleviated scar stricture, and histological detections suggested that β-elemene's effects on the MIR143HG/miR-1275/ILK axis and ILK/Akt pathway were in line with in vitro findings. Conclusions MIR143HG and ILK may act as ceRNA to sponge miR-1275. The MIR143HG/miR-1275/ILK axis mediates β-elemene-induced cell cycle arrest and apoptosis of airway granulation fibroblasts by modulating the ILK/Akt pathway, thereby inhibiting airway granulation proliferation and ultimately alleviating airway stenosis.

Abstract Background Mesothelin is a 40-kDa glycoprotein that is highly overexpressed in various types of cancers, however molecular mechanism of mesothelin has not been well-known. Amatuximab is a chimeric monoclonal IgG1/k antibody targeting mesothelin. We recently demonstrated that the combine therapy of Amatuximab and gemcitabine was effective for peritonitis of pancreatic cancer in mouse model. Methods We discover the role and potential mechanism of mesothelin blockage by Amatuximab in human pancreatic cells both expressing high or low level of mesothelin in vitro experiment and peritonitis mouse model of pancreatic cancer. Results Mesothelin blockage by Amatuximab lead to suppression of invasiveness and migration capacity in AsPC-1 and Capan-2 (high mesothelin expression) and reduce levels of pMET expression. The combination of Amatuximab and gemcitabine suppressed proliferation of AsPC-1 and Capan-2 more strongly than gemcitabine alone. These phenomena were not observed in Panc-1 and MIA Paca-2 (Mesothelin low expression). We previously demonstrated that Amatuximab reduced the peritoneal mass in mouse AsPC-1 peritonitis model and induced sherbet-like cancer cell aggregates, which were vanished by gemcitabine. In this study, we showed that the cancer stem cell related molecule such as ALDH1, CD44, c-MET, as well as proliferation related molecules, were suppressed in sherbet-like aggregates, but once sherbet-like aggregates attached to peritoneum, they expressed these molecules strongly without the morphological changes. Conclusions Our work suggested that Amatuximab inhibits the adhesion of cancer cells to peritoneum and suppresses the stemness and viability of those, that lead to enhance the sensitivity for gemcitabine.

Background: Preaxial polydactyly (PPD) is one of the most common developmental malformations, with a prevalence of 0.8–1.4% in Asians. PPD is divided into four types, PPD I–IV, and PPD I is the most frequent type. Only six loci (GLI1, GLI3, STKLD1, ZRS, pre-ZRS, and a deletion located 240 kb from SHH) have been identified in non-syndromic PPD cases. However, pathogenesis of most PPD patients has never been investigated. This study aimed to understand the genetic mechanisms involved in the etiology of PPD I in a family with multiple affected members.Methods: We recruited a PPD I family (PPD001) and used stepwise genetic analysis to determine the genetic etiology. In addition, for functional validation of the identified GLIS1 variant, in vitro studies were conducted. GLIS1 variants were further screened in additional 155 PPD cases.Results: We identified a GLIS1 variant (NM_147193: c.1061G > A, p.R354H) in the PPD001 family. In vitro studies showed that this variant decreased the nuclear translocation of GLIS1 and resulted in increased cell viability and migration. RNA sequencing revealed abnormal TBX4 and SFRP2 expression in 293T cells transfected with mutant GLIS1. Additionally, we identified a GLIS1 variant (c.664G > A, p.D222N) in another PPD case.Conclusion: We identified two GLIS1 variants in PPD I patients and first linked GLIS1 with PPD I. Our findings contributed to future molecular and clinical diagnosis of PPD and deepened our knowledge of this disease.

Abstract Background: Esophageal squamous cell carcinoma (ESCC) is a fatal disease with poor prognosis. The predominant reason for ESCC-related death is metastasis caused by tumor cell invasion. Human MENA protein is a member of Ena/Vasp family, which plays a critical role during tumor cell invasion. However, the biological effect of MENA in ESCC cell lines remains unclear Methods: In this study, fluorescent quantitative real-time PCR (qRT-PCR) were conducted to detect the mRNA expression of MENA in tumor and para-cancer tissue, CCK-8 assay and clone formation assay were conducted to evaluate cell proliferation activity, Transwell assay and wound-healing assay were conducted to detect the changes of cell invasion and migration capacity, siRNA and MENA expression vector were constructed to explore biological function of MENA in ESCC cell lines. Western blot analysis were conducted to detect the expressions of MENA , molecular markers of epithelial-mesenchymal transition (EMT), Akt, p-Akt, MMP-2 and MMP-9 respectively in ESCC cell line. Results: The qRT-PCR experiment results showed that MENA expression in ESCC tissue of 35 patients was relatively higher than that in tissue adjacent to cancer. CCK-8 assay suggested that tumor cell proliferation capacity was suppressed followed by the knockdown of MENA expression in Mena high ESCC cell TE13 and was potentiated by the overexpression of MENA in Mena low ESCC cell TE1. Transwell assay and wound healing assay demonstrated that interfering in MENA could inhibit TE13 cells invasion and migration capacity by affecting the expressions of Matrix metalloproteinase-2(MMP-2) and Matrix metalloproteinase-9 (MMP-9), in contrast, overexpression of MENA in Mena low ESCC cell TE1 could promote invasion and migration by up-regulated expression of MMP-2 and MMP-9. Western blot analysis indicated that interfering of MENA expression could affect EMT-related molecular markers (E-cadherin, N-cadherin, Snail, Slug), Akt and p-Akt Conclusions: Our study reveal that MENA could promote the ESCC cell invasion and migration by upregulate MMP-2, MMP-9 expression and Akt activation. Meanwhile, interfering of MENA expression could affect EMT in ESCC cells. This indicated that MENA may be a potential molecular therapeutic target for ESCC metastasis

Abstract Objectives Present study aimed to illustrate the role of miR-144-3p in RA. Methods N1511 chondrocytes were stimulated by IL-1β to mimic RA injury model in vitro. Rats were subjected to injection of type II collagen to establish an in vivo RA model and the arthritis index score was calculated. Cell viability was determined by CCK-8. The expression of cartilage extracellular matrix proteins (Collagen II and Aggrecan) and matrix metalloproteinases protein (MMP-13) were determined by qRT-PCR and western blots. Cell apoptosis was measured by Flow cytometry. ELISA was applied to test the secretion of pro-inflammatory cytokines (IL-1β and TNF-α). Tissue injury and apoptosis were detected by HE staining and TUNEL staining. Interaction of miR-144-3p and BMP2 was verified by dual luciferase assay. Results MiR-144-3p was dramatically increased in IL-1β induced N1511 cells. MiR-144-3p depletion elevated cell viability, suppressed apoptosis, pro-inflammatory cytokine releasing, and extracellular matrix loss in IL-1β induced N1511 cells. Moreover, miR-144-3p targeted BMP2 to modulate its expression negatively. Activation of PI3K/Akt signaling compromised inhibition of BMP2 induced aggravated N1511 cell injury with IL-1β stimulation. Inhibition of miR-144-3p alleviated cartilage injury and inflammatory in RA rats. Conclusion Collectively, miR-144-3p could aggravate chondrocytes injury inflammatory response in RA via BMP2/PI3K/Akt axis.

Abstract Background PRC1 (Protein regulator of cytokinesis 1) regulates microtubules organization and functions as a novel regulator in Wnt/β-catenin signaling pathway. Wnt/β-catenin is involved in development of liver fibrosis (LF). We aim to investigate effect and mechanism of PRC1 on liver fibrosis. Methods Carbon tetrachloride (CCl4)-induced mice LF model was established and in vitro cell model for LF was induced by mice primary hepatic stellate cell (HSC) under glucose treatment. The expression of PRC1 in mice and cell LF models was examined by qRT-PCR (quantitative real-time polymerase chain reaction), western blot and immunohistochemistry. MTT assay was used to detect cell viability, and western blot to determine the underlying mechanism. The effect of PRC1 on liver pathology was examined via measurement of aspartate aminotransferase (AST), alanine aminotransferase (ALT) and hydroxyproline, as well as histopathological analysis. Results PRC1 was up-regulated in CCl4-induced mice LF model and activated HSC. Knockdown of PRC1 inhibited cell viability and promoted cell apoptosis of activated HSC. PRC1 expression was regulated by Wnt3a signaling, and PRC1 could regulate downstream β-catenin activation. Moreover, PRC1 could activate glioma-associated oncogene homolog 1 (GLI1)-dependent osteopontin expression to participate in LF. Adenovirus-mediated knockdown of PRC1 in liver attenuated LF and reduced collagen deposition. Conclusions PRC1 aggravated LF through regulating Wnt/β-catenin mediated GLI1-dependent osteopontin expression, providing a new potential therapeutic target for LF treatment.

BackgroundNonfunctioning pituitary neuroendocrine tumor (NF-PitNET) is difficult to resect. Except for surgery, there is no effective treatment for NF-PitNET. MicroRNA-134 (miR-134) has been reported to inhibit proliferation and invasion ability of tumor cells. Herein, the mechanism underlying the effect of miR-134 on alleviating NF-PitNET tumor cells growth is explored.MethodsMouse pituitary αT3-1 cells were transfected with miR-134 mimics and inhibitor, followed by treatment with stromal cell-derived factor-1α (SDF-1α) in vitro. MiR-134 expression level: we used quantitative real-time PCR (qRT-PCR) to detect the expression of miR-134. Cell behavior level: cell viability and invasion ability were assessed using a cell counting kit-8 (CCK8) assay and Transwell invasion assay respectively. Cytomolecular level: tumor cell proliferation was evaluated by Ki-67 staining; propidium iodide (PI) staining analyzed the effect of miR-134 on cell cycle arrest; western blot analysis and immunofluorescence staining evaluated tumor migration and invasive ability. Additionally, we collected 27 NF-PitNET tumor specimens and related clinical data. The specimens were subjected to qRT-PCR to obtain the relative miR-134 expression level of each specimen; linear regression analysis was used to analyze the miR-134 expression level in tumor specimens and the age of the NF-PitNET population, gender, tumor invasion, prognosis, and other indicators.ResultsIn vitro experiment, miR-134 was observed to significantly inhibit αT3-1 cells proliferation characterized by inhibited cell viability and expressions of vascular endothelial growth factor A (VEGFA) and cell cycle transition from G1 to S phase (P < 0.01). VEGFA was verified as a target of miR-134. Additionally, miR-134-induced inhibition of αT3-1 cell proliferation and invasion was attenuated by SDF-1α and VEGFA overexpression (P < 0.01). In primary NF-PitNET tumor analysis, miR-134 expression level was negatively correlated with tumor invasion (P = 0.003).ConclusionThe regulation of the SDF-1α/miR-134/VEGFA axis represents a novel mechanism in the pathogenesis of NF-PitNETs and may serve as a potential therapeutic target for the treatment of NF-PitNETs.
