    ABSTRACT: We hypothesized that matrix metalloproteinase secretion in response to cigarette smoke is modulated by cross-talk between resident cells within the aorta, namely, aortic smooth muscles, endothelial cells, and infiltrating macrophages, and this may be crucial for in vivo formation/progression of abdominal aortic aneurysm (AAA). Cigarette smoke extract (CSE) was applied to rat aortic smooth muscle (RASMC), endothelial (RAEC) or RAW cells, and conditioned media (CSE-CM) collected. Fresh cells were treated with CSE-CM for 24 h and then maintained in serum-free medium (SFM) for 72 h to analyze MMP2 and MMP9 in media by zymography and the ratio (pS/pJ) of phospho-Stat3 (pStat3) and phospho-Jak2 (pJak2) inside the cells by Western blot. We observed that CSE-CM from RAW and RAEC increased MMP9 by 200 and 17 %, respectively, in RASMC and also increased pS/pJ ratio (305 and 228 %, respectively) in RASMC. RAW cell-derived CSE-CM induced RAEC to produce moderate amounts of MMP2 (17 %), MMP9 (30 %), and a 137 % increase in pS/pJ. RAW cells receiving unstimulated CM from RASMC and RAEC produced significant amounts of MMP9 (128 and 155 %, respectively) and increased pS/pJ (45 and 1283 %, respectively). CSE-CM from RASMC and RAEC induced significant production of MMP9 from RAW cells (237 and 162 %, respectively) and increase in pS/pJ ratios (1348 and 1494 %, respectively). This is the first in vitro study demonstrating cigarette smoke extract-mediated differential interactions between resident cells in the aorta leads to altered modulation of signaling molecules that may be vital for AAA formation under in vivo conditions.

    ABSTRACT: Muscle wasting impairs physical function and leads people to a bedridden state. We previously demonstrated that lysine (Lys) suppresses autophagic-proteolysis through the Akt pathway. However, the effect of metabolites of Lys on proteolysis is unclear. In this study, we investigated the effect of saccharopine (Sac), a metabolite of Lys, on proteolysis in C2C12 cells. When C2C12 myotubes were incubated in serum-free medium containing Sac, the rate of proteolysis, which was evaluated by 3-methylhistidine released from C2C12 myotubes, and autophagy activity, which was assessed by amount of light chain 3-II, were suppressed. Sac stimulated Akt and mammalian target of rapamycin signaling, which was evaluated from eIF4E-binding protein 1 phosphorylation. The suppressive effects of Sac on proteolysis and autophagy were completely abolished by an Akt inhibitor. Therefore, we concluded that Sac suppresses autophagic-proteolysis through Akt as with Lys.

    ABSTRACT: Adult stem cells have more restricted differentiation potential than embryonic stem cells (ESCs), but upon appropriate stimulation can differentiate into cells of different germ layers. Epigenetic factors, including DNA modifications, take a significant part in regulation of pluripotency and differentiation of ESCs. Less is known about the epigenetic regulation of these processes in adult stem cells. Gene expression profile and location of DNA modifications in adipose-derived stem cells (ADSCs) and their osteogenically differentiated lineages were analyzed using Agilent microarrays. Methylation-specific PCR and restriction-based quantitative PCR were applied for 5-methylcytosine (5mC) and 5-hydroxymethylcytosine (5hmC) detection in selected loci. The level of DNA modifications in the POU5F1 locus was quantified with deep sequencing. Expression levels of selected genes were assayed by real-time PCR. ADSCs differentiation into osteogenic lineages involved marked changes in both 5mC and 5hmC profiles, but 5hmC changes were more abundant. 5mC losses and 5hmC gains were the main events observed during ADSCs differentiation, and were accompanied by increased expression of TET1 (P = 0.009). In ADSCs, POU5F1 was better expressed than NANOG or SOX2 (P ≤ 0.001). Both 5mC and 5hmC marks were present in the POU5F1 locus, but only hydroxymethylation of specific cytosine showed significant effect on the gene expression. In summary, the data of our study suggest significant involvement of changes in 5hmC profile during the differentiation of human adult stem cells.

    ABSTRACT: Signaling through the Janus kinase/signal transducers and activators of transcription (JAK/STAT) pathway, especially JAK2/STAT3, is involved in renal fibrosis. Fluorofenidone (FD), a novel pyridone agent, exerts anti-fibrotic effects in vitro and in vivo. Herein, we sought to investigate whether FD demonstrates its inhibitory function through preventing JAK2/STAT3 pathway. In this study, we examined the effect of FD on activation of rat renal interstitial fibroblasts, glomerular mesangial cells (GMC), and expression of JAK2/STAT3. Moreover, we explored the histological protection effects of FD in UUO rats, db/db mice, and phosphorylation of JAK2/STAT3 cascade. Our studies found that pretreatment with FD resulted in blockade of activation of fibroblast and GMC manifested by fibronectin (FN) and α-smooth muscle actin (α-SMA) protein expression and decline of STAT3 tyrosine phosphorylation induced by IL-6 or high glucose. In unilateral ureteral obstruction rats and a murine model of spontaneous type 2 diabetes (db/db mice), treatment with FD blocked the expression of FN and α-SMA, prevented renal fibrosis progression, and attenuated STAT3 activation. However, FD administration did not interfere with JAK2 activation both in vivo and in vitro. In summary, the molecular mechanism by which FD exhibits renoprotective effects appears to involve the inhibition of STAT3 phosphorylation.

    ABSTRACT: Bone cells respond to various mechanical stimuli including fluid shear stress (FSS) in vitro. Induction of cyclooxygenase-2 (COX-2) is thought to be important for the anabolic effects of mechanical loading. Recently, extracellular-signal-regulated kinase 5 (ERK5) has been found to be involved in multiple cellular processes. However, the relationship between ERK5 and the induction of COX-2 is still unknown. Here, we investigated the potential involvement of ERK5 in the response of pre-osteoblastic MC3T3-E1 cells upon FSS. MC3T3-E1 cells were subjected to 12 dyn/cm2 FSS. Then, we established a ERK5 small interfering RNA (siRNA) transfected cell line using the MC3T3-E1 cells. After the successful transfection confirmed by real-time reverse transcription-polymerase chain reaction and Western blotting, the expression of COX-2, cAMP response element-binding protein (CREB), and nuclear factor kappa B cells (NF-κB) were assayed for downstream effectors of activated ERK5 under FSS by Western blotting. Our results showed that FSS could stimulate COX-2 activity, and induce the phosphorylation of ERK5, CREB, and NF-κB. When the MC3T3-E1 cells were transfected using siRNA before exposure to FSS, COX-2 activity was suppressed, and the phosphorylation of CREB and NF-κB was significantly downregulated. In summary, we demonstrated that ERK5 pathway is essential in the induction of COX-2 gene

    ABSTRACT: Cardiomyocyte hypertrophy is an adaptive response of heart to various stress conditions. During the period of stress accumulation, transition from physiological hypertrophy to pathological hypertrophy results in the promotion of heart failure. Our previous studies found that ZAK, a sterile alpha motif and leucine zipper containing kinase, was highly expressed in infarcted human hearts and demonstrated that overexpression of ZAK induced cardiac hypertrophy. This study evaluates, cellular events associated with the expression of two doxycycline (Dox) inducible Tet-on ZAK expression systems, a Tet-on ZAK WT (wild-type), and a Tet-on ZAK DN (mutant, Dominant-negative form) in H9c2 myoblast cells; Tet-on ZAK WT was found to increase cell size and hypertrophic marker BNP in a dose-dependent manner. To ascertain the mechanism of ZAK-mediated hypertrophy, expression analysis with various inhibitors of the related upstream and downstream proteins was performed. Tet-on ZAK WT expression triggered the p38 and JNK pathway and also activated the expression and nuclear translocation of p-GATA4 and p-c-Jun transcription factors, without the involvement of p-ERK or NFATc3. However, Tet-on ZAK DN showed no effect on the p38 and JNK signaling cascade. The results showed that the inhibitors of JNK1/2 and p38 significantly suppressed ZAK-induced BNP expression. The results show the role of ZAK and/or the ZAK downstream events such as JNK and p38 phosphorylation, c-Jun, and GATA-4 nuclear translocation in cardiac hypertrophy. ZAK and/or the ZAK downstream p38, and JNK pathway could therefore be potential targets to ameliorate cardiac hypertrophy symptoms in ZAK-overexpressed patients.

    ABSTRACT: The pink-eyed dilution protein (P-protein) plays a critical role in melanin synthesis in melanocytes and retinal pigment epithelium cells. Mutation in this protein may cause complete or partial albinism. Role of the P-protein ranges in melanin synthesis to maturation and trafficking of the melanosomes. The aim of the present study was to evaluate the effect of P-protein inhibition on melanosome biology by comparing the shape, size, count, and types of melanosomes in melan-a melanocytes. The cells were extensively examined by the transmission electron microscopy. The P-protein inhibition was carried by P-protein-siRNA transfection to melan-a melanocytes, B16F10 mouse melanoma, and melan-p1 cells. Measurement of melanin contents, cellular tyrosinase, and different tyrosinase related proteins were also determined to investigate the effect of P-protein siRNA transfection on melanocytes. Results suggested that the inhibition of P-protein can significantly change the melanosomal morphology, types and their respective numbers, and provided a novel strategy for the control of melanin synthesis.

    ABSTRACT: Phosphatidylinositol 3-kinase (PI3-K)/PTEN/Akt signaling is over activated in various tumors including colon cancer. Activation of this pathway regulates multiple biological processes such as apoptosis, metabolism, cell proliferation, and cell growth that underlie the biology of a cancer cell. In the present study, the chemopreventive effects have been observed of Diclofenac, a preferential COX-2 inhibitory non-steroidal anti-inflammatory drugs, and Curcumin, a natural anti-inflammatory agent, in the early stage of colorectal carcinogenesis induced by 1,2-dimethylhydrazine dihydrochloride in rats. The tumor-promoting role of PI3-K/Akt/PTEN signal transduction pathway and its association with anti-apoptotic family of proteins are also observed. Both Diclofenac and Curcumin downregulated the PI3-K and Akt expression while promoting the apoptotic mechanism. Diclofenac and Curcumin administration significantly increased the expression of pro-apoptotic Bcl-2 family members (Bad and Bax) while decreasing the anti-apoptotic Bcl-2 protein. An up-regulation of cysteine protease family apoptosis executioner, such as caspase-3 and -9, is seen. Diclofenac and Curcumin inhibited the Bcl-2 protein by directly interacting at the active site by multiple hydrogen bonding, as also evident by negative glide score of Bcl-2. These drugs stimulated apoptosis by increasing reactive oxygen species (ROS) generation and simultaneously decreasing the mitochondrial membrane potential (ΔΨ M). Diclofenac and Curcumin showed anti-neoplastic effects by downregulating PI3-K/Akt/PTEN pathway, inducing apoptosis, increasing ROS generation, and decreasing ΔΨ M. The anti-neoplastic and apoptotic effects were found enhanced when both Diclofenac and Curcumin were administered together, rather than individually.

    ABSTRACT: Circulating microRNAs (miRNAs) in patient body fluids have recently been considered to hold the potential of being novel disease biomarkers and drug targets. We aimed to investigate the correlation between the levels of circulating miR-214 and the expression of vascular endothelial growth factor (VEGF) in the pathogenesis of coronary heart disease patients to further explore the mechanism involved in the vasculogenesis. Three different cohorts, including 13 acute myocardial infarction patients, 176 angina pectoris patients, and 127 control subjects, were enrolled to investigate the expression levels of circulating miR-214 in patients with myocardial ischemia and also the relationship between plasma miR-214 and severity of coronary stenosis. Plasma miR-214 levels of participants were examined by real-time quantitative PCR. Simultaneously, plasma cardiac troponin I concentrations were measured by ELISA assays. We further detected the correlation of miR-214 and VEGF by molecular and animal assays. MiR-214 was enriched in not only diseased endothelial progenitor cells (EPCs) but also the plasma of coronary artery disease (CAD) patients. Besides, we found out miR-214 was able to suppress VEGF expression and EPC activities. Reporter assays confirmed the direct binding and repression of miR-214 to the 39-UTR of VEGF mRNA. Knockdown of miR-214 not only restored VEGF levels and angiogenic activities of diseased EPCs in vitro, but also further promoted blood flow recovery in ischemic limbs of mice. Circulating miR-214 may be a new biomarker for CAD and as a potential diagnostic tool. And increased miR-214 level may be used to predict the presence and severity of coronary lesions in CAD patients.

    ABSTRACT: The aim of the present study was to analyze the expression of sex-determining region Y-related high mobility group box 4 (SOX4) in non-small cell lung cancer (NSCLC) and its correlation with clinicopathologic characteristics, including the survival of NSCLC patients. To observe initially the expression status of SOX4 in lung squamous cell carcinoma and adenocarcinoma at gene expression omnibus. The expression of SOX4 mRNA and protein was examined in NSCLC tissues and normal lung tissues through real-time PCR and immunohistochemistry. Meanwhile, the relationship of SOX4 expression levels with clinical characteristics of 168 NSCLC patients was analyzed by immunohistochemistry. Univariate and multivariate analyses were performed to determine the association between SOX4 expression and prognosis of NSCLC patients. In our results, SOX4 expression was increased in NSCLC tissues compared with paired normal lung tissues in microarray data (GSE3268). SOX4 mRNA and protein expression were markedly higher in NSCLC tissues than in normal lung tissues (P = 0.001 and P = 0.001, respectively). Using immunohistochemistry, high levels of SOX4 protein were positively correlated with status of differentiated degree (high vs. middle, P = 0.004; high vs. low, P P P = 0.004), N classification (N0–N1 vs. N2–N3, P = 0.002), and M classification (M0 vs. M1, P = 0.011) in NSCLC. Moreover, the higher level of SOX4 expression was markedly correlated with poor overall survival in NSCLC patients (P NSCLC patients (P = 0.002). In conclusion, SOX4 plays an important role on NSCLC progression and prognosis and may serve as a convictive prognostic biomarker for NSCLC patients.

    ABSTRACT: Interleukin-12 (IL-12), a member of interleukin family, plays a critical role in immune responses and anti-tumor activity. In this study, the effects of IL-12 on monocytic tumor cell lines differentiation to macrophagocyte and its likely mechanism was investigated. We examined the differentiation markers, morphological and functional changes, and possible mechanism in IL-12-treated THP-1 and U937 cells. It was found that IL-12 could up-regulated macrophage surface marker CD68 and CD11b expression in a time-dependent manner. Morphologically, after IL-12 treatment, THP-1 and U937 cells became round or irregular shape, even stretched many cell membrane protuberances; some cell nuclei became fuzzy or completely disappeared, and the chromatin appeared dense and cordlike. Furthermore, IL-12-induced monocytic tumor cell differentiation was accompanied by the growth arrest with G1-phase accumulation and S-phase reduction; apoptosis increased with anti-apoptosis protein Bcl-2 down-expression and pro-apoptosis protein Fas up-regulation, and enhanced phagocytosis function. The IL-12-induced macrophage differentiation of THP-1 and U937 cells was associated with the up-regulation of c-fms expression and the CSF-1R Tyr 809 site phosphorylation. These findings have revealed that IL-12 could induce monocytic tumor cells directional differentiation into macrophage-like cells, and its mechanism is possible connected with the up-regulation of c-fms expression and the phosphorylation of CSF-1R Tyr-809 site.

    ABSTRACT: Osteoporosis, a systemic bone disorder, is prevalent in postmenopausal woman. Bone mesenchymal stem cells (BMSCs), precursors of osteogenic cells, may contribute to prevention or treatment of bone frustrate in osteoporosis. Recently, two studies suggested a role of calcitonin gene-related peptide (CGRP) in promoting osteogenesis of BMSCs under physiological conditions. However, the role of CGRP on BMSCs, which are derived from osteoporotic tissues, is unclear. Here, we investigated the role of CGRP on BMSCs isolated from female osteoporotic rats. Data showed that CGRP stimulated cell proliferation and inhibited cell apoptosis for short-term culture of BMSCs. Instead, CGRP induced BMSCs differentiation into the osteoblasts and promoted formation of calcified nodules after long-term culture. Moreover, CGRP gradually up-regulated expression levels of osteoporotic differentiation-related genes including alkaline phosphatase, Collagen type I, Bmp2, Osteonectin, and Runx2 during osteogenic differentiation. In conclusion, CGRP promoted proliferation and induced osteogenic differentiation and mineralization during female osteoporotic rat-derived BMSC differentiation. These findings support a potential role of CGRP on the prevention or treatment of osteoporotic fracture.
