  • Age and sex differences in microRNAs expression during the process of
           thymus aging
    • Authors: Guo D; Ye Y, Qi J, et al.
      Abstract: <span class="paragraphSection"><div class="boxTitle">Abstract</div>The gender-biased thymus involution and the importance of microRNAs (miRNAs, miRs) expression in modulating the thymus development have been reported in many studies. However, how males and females differ in so many ways in thymus involution remains unclear. To address this question, we investigated the miRNA expression profiles in both untreated 3- and 12-month-old female and male mice thymuses. The results showed that 7 and 18 miRNAs were defined as the sex- and age-specific miRNAs, respectively. The expression of miR-181c-5p, miR-20b-5p, miR-98b-5p, miR-329-3p, miR-341-5p, and miR-2137 showed significant age-difference in mice thymus by quantitative polymerase chain reaction. High expression levels of miR-2137 were detected in mice thymic epithelial cells and gradually increased during the process of thymus aging. MiR-27b-3p and miR-378a-3p of the female-biased miRNAs were confirmed as the sex- and estrogen-responsive miRNAs in mice thymus <span style="font-style:italic;">in vivo</span>. Their potential target genes and the pathway were identified by the online software. Possible regulation roles of sex- and age-specific miRNA expression during the process of thymus aging were discussed. Our results suggested that these miRNAs may be potential biomarkers for the study of sex- and age-specific thymus aging and involution.</span>

  • Age-dependent down-regulation of hyperpolarization-activated cyclic
           nucleotide-gated channel 4 causes deterioration of canine sinoatrial node
           function
    • Authors: Du J; Deng S, Pu D, et al.
      Abstract: <span class="paragraphSection"><div class="boxTitle">Abstract</div>The activity of pacemaker cells in the sinoatrial node (SAN) is an indicator of normal sinus rhythm. Clinical studies have revealed that the dysfunction of the SAN progressively increases with aging. In this study, we determined the changes in hyperpolarization-activated cyclic nucleotide-gated channel 4 (HCN4) expression and the relationship between aging and canine SAN dysfunction. The results of cardiac electrophysiological determination revealed that the intrinsic heart rate decreased from 168 ± 11 beats min<sup>−1</sup> in young canines to 120 ± 9 beats min<sup>−1</sup> in adults and to 88 ± 9 beats min<sup>−1</sup> in aged canines. The sinus node recovery time (SNRT) increased from 412 ± 32 ms in young canines to 620 ± 56 ms in adults and to 838 ± 120 ms in aged canines. Corrected SNRT (CSNRT) increased from 55 ± 12 ms in young canines to 117 ± 27 ms in adults and to 171 ± 37 ms in aged canines. These results indicated that SAN function deteriorated with aging in the canine heart. However, histological staining illustrated that fibrosis was not significantly increased with aging in canine SAN. Real-time polymerase chain reaction indicated that the expression of <span style="font-style:italic;">HCN4</span> mRNA was downregulated in the elderly canine SAN. Similarly, we also verified that HCN4 protein expression within the SAN declined with aging via immunofluorescence staining and western blot analysis. Taken together, our data show that electrical remodeling, related to the down-regulation of HCN4, is responsible for the gradually increased incidence of SAN dysfunction with aging. Our results provide further evidence for explaining the mechanisms of age-related deterioration in the SAN.</span>

It has been reported that <span style="font-style:italic;">Twist</span> is a target gene of STAT3, and STAT3/Twist signaling plays an important role in regulating cancer progress. Here, to explore whether 8-bromo-7-methoxychrysin (BrMC) inhibits liver cancer stem-like cell (LCSLC) properties via disrupting STAT3/Twist signaling, we cultured SMMC-7721 cells <span style="font-style:italic;">in vitro</span>, and evaluated the effects of BrMC on the stemness of spheroids by determining the sphere-forming capability and migration. The sphere formation assay results showed a concentration-dependent decrease of sphere-forming capacity in LCSLCs (<span style="font-style:italic;">P</span> < 0.05) treated with different concentrations of BrMC. Wound-healing assays results demonstrated a concentration-dependent decline in cell migration of LCSLCs treated with different concentrations of BrMC. In addition, CD133, CD44, and ALDH1 levels were decreased in LCSLCs treated with BrMC. Treatment with different concentrations of BrMC also reduced the expressions of p-STAT3 and Twist1 proteins. The effect of BrMC was substantially enhanced by co-treatment with JSI-124, a specific inhibitor of STAT3. Ectopic expression of Twist1 attenuated the inhibitory effects of BrMC on sphere formation, migration, and expression of the markers in LCSLCs. However, it had no affect on p-STAT3 expression in LCSLCs. These results demonstrated that BrMC inhibits the stemness of LCSLCs originated from SMMC-7721 cell line by inhibiting STAT3/Twist signal axis.</span>

  • Protective role and related mechanism of Gnaq in neural cells damaged by
           oxidative stress
    • Authors: Jia N; Li G, Huang P, et al.
      Abstract: <span class="paragraphSection"><div class="boxTitle">Abstract</div>Gnaq is a member of G protein family and is rich in brain tissue. It has attracted the attention of many researchers in melanoma due to its high ratio of mutation. We have previously reported that the expression level of Gnaq in the mouse forebrain cortex was significantly decreased with age. Oxidative stress (OS) is the main cause leading to brain aging and related diseases. The roles and mechanisms of Gnaq in antioxidation in the brain have not been fully explored. In the present study, gene recombinant technique and lentivirus transfection technique were used to generate a Gnaq-overexpression cell model (Gnaq-SY5Y) coupled with H<sub>2</sub>O<sub>2</sub> to build an OS model. The viability of cells, concentration of reactive oxygen species (ROS), apoptosis-related proteins (Bcl-2 and Bax), and signal pathways (NF-κB and Erk1/2) were compared between model cells and control cells. Results showed that the antioxidative ability of Gnaq-SY5Y cells was significantly improved. Concomitantly, the ROS level in Gnaq-SY5Y cells was significantly decreased whether the cells were subject to or not to H<sub>2</sub>O<sub>2</sub> treatment. Anti-apoptotic protein Bcl-2 was up-regulated and apoptosis-promoting protein Bax was down-regulated in Gnaq-SY5Y cells after treatment with H<sub>2</sub>O<sub>2</sub>. NF-κB and phosphorylated Erk1/2 (p-Erk1/2) was significantly down-regulated in Gnaq-SY5Y cells. H<sub>2</sub>O<sub>2</sub> treatment decreased Gnaq expression but increased NF-κB and p-Erk1/2 expressions in Gnaq-SY5Y cells. It is therefore concluded that Gnaq plays a pivotal role in antioxidation in neural cells. A possible mechanism for this would be that the overexpressed Gnaq inhibits the cellular damaging effect mediated by NF-κB and Erk1/2 signal pathways.</span>

  • MiR-218 suppresses the metastasis and EMT of HCC cells via targeting
           SERBP1
    • Authors: Wang T; Xu L, Jia R, et al.
      Abstract: <span class="paragraphSection"><div class="boxTitle">Abstract</div>Hepatocellular carcinoma (HCC) is the leading cause of cancer-related deaths worldwide. Although many efforts for treating HCC have been made, the survival rate remains unsatisfied. Accumulating evidence indicates that microRNA-218 (miR-218) functions as a tumor suppressor and involves in many biological processes such as tumor initiation, development, and metastasis in certain types of human cancers. However, the potential function and underlying molecular mechanism of miR-218 in HCC still remains to be elucidated. Since HCC is a genetic disease, exploring the mechanisms of the pathogeny and integration are essential for the discovery of novel treatment targets for HCC. Therefore, the aim of the present study was to investigate the abnormal expression level of miR-218 in clinical HCC tissues and HCC cells, and to evaluate its function and underlying mechanisms in HCC. Our results revealed that miR-218 expression was significantly downregulated in HCC tissues and cell lines. Gain-of-function and loss-of-function assays indicated that forced expression of miR-218 in HCC cells inhibited cell migration/invasion and reversed epithelial–mesenchymal transition (EMT) to mesenchymal–epithelial transition (MET), while deletion of miR-218 promoted cell migration/invasion and contributed to the EMT phenotype formation. Bioinformatics analysis and luciferase reporter assay confirmed that serpine mRNA binding protein 1 (SERBP1) was a target gene of miR-218 and rescue assay further confirmed that SERBP1 involved in the function of miR-218 in HCC. All these results suggested that miR-218/SERBP1 signal pathway could inhibit the malignant phenotype formation and that targeting this pathway may be a potential novel way for HCC therapeutics.</span>

  • Progressive silencing of the zinc transporter Zip8 (Slc39a8) in chronic
           cadmium-exposed lung epithelial cells
    • Authors: Gao Y; Xu Y, Wu D, et al.
      Abstract: <span class="paragraphSection"><div class="boxTitle">Abstract</div>Cadmium (Cd), a non-essential metal, stealthily enters the cells by utilizing the essential metal importing pathways. The zinc transporters Zip8, Zip14, and divalent metal transporter 1 (Dmt1) are now emerging as several important metal transporters involved in cellular Cd incorporation and their expressions have been shown to be down-regulated in several Cd-resistant (Cd<sup>R</sup>) cell lines, however, the involvement of these transporters during the development of Cd-resistance in lung cells is unclear. In this study, we therefore check the expression of these metal transporters in our previously established rat lung epithelial cells (LECs) and show that the level of Zip8 is progressively silenced when LECs are adapted to increasing concentrations of CdCl<sub>2</sub> (from 1 to 20 μM). Subsequent measurement of the cellular Cd content indicated that Cd<sup>R</sup> LECs exhibit a marked decrease of Cd accumulation, possibly due to the loss of Zip8 expression. We investigate the possibility that epigenetic silencing of the <span style="font-style:italic;">Zip8</span> gene by DNA hypermethylation is involved in the down-regulation of Zip8 expression. Cd<sup>R</sup> LECs show a higher mRNA level of DNA methyltransferase 3b (Dnmt3b) than parental cells. Treatment of Cd<sup>R</sup> LECs with 5-aza-2′-deoxycytidine, an inhibitor of DNA methyltransferases, reverted the expression of Zip8 and sensitivity to Cd in these cells, indicating the critical role of Zip8 for Cd import. Taken together, our results demonstrate that the progressive silencing of Zip8 expression is involved in the acquisition of resistance against Cd in lung cells, representing an adaptive survival mechanism that resists Cd-induced cytotoxicity.</span>

  • Molecular cloning and characterization of antimicrobial peptides from skin
           of Hylarana guentheri
    • Authors: Dong Z; Luo W, Zhong H, et al.
      Abstract: <span class="paragraphSection"><div class="boxTitle">Abstract</div>The cDNAs encoding antimicrobial peptides (AMPs) in the skin of <span style="font-style:italic;">Hylarana guentheri</span> were identified, namely temporin (five peptides, termed temporin-GHa–GHd and temporin-GUa), brevinin-1 (one peptide, brevinin-1GUb), and brevinin-2 (eight peptides, brevinin-2GHd–2GHj, and brevinin-2GHb). Eleven of the 14 peptides have novel primary structures. Synthesized temporin GHa-GHd have broad-spectrum antimicrobial activities against Gram-positive bacteria (<span style="font-style:italic;">Staphylococcus aureus</span> and <span style="font-style:italic;">Bacillus subtilis</span>), Gram-negative bacteria (<span style="font-style:italic;">Escherichia coli</span>, <span style="font-style:italic;">Vibrio alginolyticus</span>, and <span style="font-style:italic;">Pseudomonas aeruginosa</span>), as well as fungus (<span style="font-style:italic;">Candida albicans</span>). Among these tested strains, <span style="font-style:italic;">S. aureus</span> was the most sensitive to temporin-GHa–GHd with minimum inhibitory concentration (MIC) values between 6.8 and 12.9 μM. They also exhibited antimicrobial activities against Methicillin-resistant <span style="font-style:italic;">S. aureus</span> with the MIC ranging from 12.7 to 51.7 μM. Interestingly, secondary structure prediction shows that there is no α-helix in temporin-GHb, which illustrates that α-helix is not required for the antimicrobial activity of temporin-GHb. NaCl (at final concentrations of 0.15–2 M) decreased the antimicrobial activity of temporin-GHa–GHd slightly, while human serum and <span style="font-style:italic;">S. aureus</span> V8 proteinase had no effect on the antimicrobial activity. Scanning electron microscopy images of <span style="font-style:italic;">E. coli</span> and <span style="font-style:italic;">S. aureus</span> showed that the surface of microbial cells was considerably rough and shrived after 1 h of treatment with temporin-GHa–GHd at 37°C. The stabilities of temporin-GHa–GHd in human serum or in <span style="font-style:italic;">S. aureus</span> V8 proteinase make them to be promising candidates of novel antimicrobial agents or models for the development of novel AMPs.</span>

  • miR-30e is negatively regulated by myostatin in skeletal muscle and is
           functionally related to fiber-type composition
    • Authors: Jia H; Zhao Y, Li T, et al.
      Abstract: <span class="paragraphSection"><div class="boxTitle">Abstract</div>Myostatin (MSTN) negatively regulates skeletal myogenesis in which microRNAs (miRNAs) also play critical roles. Using miRNA microarrays of skeletal muscle from MSTN-knockout (MSTN<sup>−/−</sup>) mice, we recently showed that miR-431 is regulated by MSTN signaling. To identify additional miRNAs regulated by MSTN, we re-analyzed these miRNA arrays and validated their expression by quantitative RT-PCR. Herein, we demonstrated that miR-30e was significantly upregulated in skeletal muscle of MSTN<sup>−/−</sup> mice compared with that of the wild-type littermates. Importantly, the predicted targets of miR-30e are functionally involved in myocyte differentiation and fiber-type formation. Using luciferase reporter gene assays, we further showed that peroxisome proliferator-activated receptor gamma, coactivator 1 alpha (<span style="font-style:italic;">Pgc1α</span>), is a direct target of miR-30e. Overexpression of miR-30e in C2C12 cells significantly decreased <span style="font-style:italic;">Pgc1α</span> and increased type II form of myosin heavy chain gene expression, suggesting that miR-30e functionally associates with glycolytic myofiber formation. Thus, our data indicate that the altered fiber-type composition in MSTN<sup>−/−</sup> mice are attributable in part to deregulated expression of miR-30e.</span>

  • Dihydrocelastrol inhibits multiple myeloma cell proliferation and promotes
           apoptosis through ERK1/2 and IL-6/STAT3 pathways in vitro and in vivo
    • Authors: Hu L; Wu H, Li B, et al.
      Abstract: <span class="paragraphSection"><div class="boxTitle">Abstract</div>Multiple myeloma (MM) is the second most frequent malignant hematological disease. Dihydrocelastrol (DHCE) is synthesized by hydrogenated celastrol, a treterpene isolated from Chinese medicinal plant <span style="font-style:italic;">Tripterygium regelii</span>. In this study, we first reported the anti-tumor activity of DHCE on MM cells. We found that DHCE could inhibit cell proliferation and promote apoptosis through caspase-dependent way <span style="font-style:italic;">in vitro</span>. In addition, DHCE could inactivate the expression of interleukin (IL)-6 and downregulate the phosphorylation of extracellular regulated protein kinases (ERK1/2) and the signal transducer and activator of transcription 3 (STAT3) in MM. It also retained its activity against MM cell lines in the presence of IL-6. Furthermore, treatment of MM cells with DHCE resulted in an accumulation of cells in G<sub>0</sub>/G<sub>1</sub> phase of the cell cycle. Notably, DHCE reduced the expression of cyclin D1 and cyclin-dependent kinases 4 and 6 in MM cell lines. Additionally, its efficacy toward the MM cell lines could be enhanced in combination with the histone deacetylase inhibitor panobinostat (LBH589), which implied the possibility of the combination treatment of DHCE and LBH589 as a potential therapeutic strategy in MM. In addition, treatment of NCI-H929 tumor-bearing nude mice with DHCE (10 mg/kg/d, i.p., 1–14 days) resulted in 73% inhibition of the tumor growth <span style="font-style:italic;">in vivo</span>. Taken together, the results of our present study indicated that DHCE could inhibit cellular proliferation and induce cell apoptosis in myeloma cells mediated through different mechanisms, possibly through inhibiting the IL-6/STAT3 and ERK1/2 pathways. And it may provide a new therapeutic option for MM patients.</span>

  • Recombinant CC16 protein inhibits the production of pro-inflammatory
           cytokines via NF-κB and p38 MAPK pathways in LPS-activated RAW264.7
           macrophages
    • Authors: Pang M; Yuan Y, Wang D, et al.
      Abstract: <span class="paragraphSection"><div class="boxTitle">Abstract</div>Accumulating evidence indicates that Clara cell protein-16 (CC16) has anti-inflammatory functions, although the involved molecular pathways have not been completely elucidated. Here, we evaluated the effect of recombinant rat CC16 (rCC16) on the expression of tumor necrosis factor alpha (TNF-α), interleukin-6 (IL-6), and IL-8 in lipopolysaccharide (LPS)-stimulated mouse macrophages (RAW264.7 cells) and explored the underlying molecular mechanisms. It was found that rCC16 inhibited LPS-induced TNF-α, IL-6, and IL-8 expression at both the messenger ribonucleicacid (mRNA) level and protein level in a concentration-dependent manner, as demonstrated by real-time reverse transcriptase-polymerase chain reaction and enzyme-linked immunosorbent assay. Such suppressive effects were accompanied by the inhibition of transcriptional activity and the deoxyribonucleic acid binding activity of nuclear factor (NF)-κB but not activator protein (AP)-1. Western blot analysis further revealed that rCC16 inhibited the increase of nuclear NF-κB and the reduction of cytosolic NF-κB, the phosphorylation and reduction of NF-κB inhibitory protein IκBα, and the p38 mitogen-activated protein kinase (MAPK)-dependent NF-κB activation by phosphorylation at Ser276 of its p65 subunit. Furthermore, rCC16 was found to have no effect on the phosphorylation of c-Jun N-terminal kinase, c-Jun, or the nuclear translocation of c-Jun. In addition, reduction of TNF-α, IL-6, and IL-8 were reversed when the level of endogenous uteroglobin-binding protein was reduced by RNA interference in rCC16- and LPS-treated RAW264.7 cells. Our data suggest that rCC16 suppresses LPS-mediated inflammatory mediator TNF-α, IL-6, and IL-8 production by inactivating NF-κB and p38 MAPK but not AP-1 in RAW264.7 cells.</span>
