Background: Nile tilapia (Oreochromis niloticus), an important economic freshwater fish being cultured globally, is highly adaptable to a wide range of salinities. However, little information is currently available on the mechanism of salinity adaptation. Objective: For a better understanding of this intriguing adaptability, we identified and analyzed aquaporins (AQPs), which are channel proteins with a basic function of intracellular and intercellular transportation for water and certain solutes. Methods: In the present study, we performed genome-wide identification and comprehensive analysis of the duplicated AQP genes in Nile tilapia by bioinformatics methods. Tissue-specific analyses were then combined with transcriptome data under different salinity treatments. Results: It was revealed that Nile tilapia has a total of twenty-eight AQPs, which are distributed unevenly on twelve chromosomes and belong to four subfamilies according to phylogenetic analysis. These AQPs share conserved AQP characteristic structural domains and motifs, although they differ in molecular weight from 23 to 36 kDa and contain distinct sequences. GO analysis revealed that most AQPs have transporter protein activity and are involved in biological processes such as substance transport, stress response, development and metabolism. KEGG enrichment analysis showed that AQPs were significantly enriched in two pathways, anti-diuretic hormone-regulated reabsorption and bile secretion. Conclusion: These results suggested that Nile tilapia has a highly developed, albeit complex, osmotic pressure regulation system, which provided a molecular basis for exploring how these AQP members coordinate to help Nile tilapia cope with different salinities.

Background: Aberrations in gene methylation patterns play important roles in gliomagenesis. However, whether the ALDH1A3 promoter methylation is related to prognoses of primary glioblastomas (GBMs) in Western China remains unclear. Materials and Methods: Methylation levels of ALDH1A3 CpG island in 36 GBMs were identified by pyrophosphate sequencing, while ALDH1A3 expression was assessed with matched paraffin section immunohistochemistry. Survival curves were analysed by Kaplan-Meier. Results: The hypermethylation status of ALDH1A3 promoter predicted a better prognosis accompanied with low expression of ALDH1A3 protein. Conclusions: Our results indicate ALDH1A3 promoter methylation correlates with prognosis in primary GBMs.

Background: To investigate the relationship between pathologic tumor response to concurrent chemoradiotherapy and variation of serum VEGF in patients with esophageal cancer. Materials and Methods: Forty six patients with esophageal cancer who were treated with concurrent chemo-radiotherapy were enrolled. Endoscopic and pathologic examination was conducted before and four weeks afterwards. Serum level of VEGF was documented before, four weeks later and after chemo-radiotherapy. The relationship between pathologic response and the variation of serum level of VEGF and its influence on the prognosis were investigated. Results: Serum level of VEGF decreased remarkably during and after chemo-radiotherapy in patients whose pathologic response was severe (F=5.393, 4.587, P(0.05). There were no statistical differences of serum VEGF level before, during and after chemo-radiotherapy for patients whose pathologic response was moderate or mild. There were 18 (85.7%), 7 (53.8%) and 6 patients (50.0%) whose serum VEGF level dropped in the severe, moderate and mild group, respectively, with significant differences among these groups (p=0.046). Two year survival rates of patients with severe, moderate and mild pathologic response were 61.9%, 53.8% and 33.3% respectively, and no statistically difference between severe and mild group regarding OS (p=0.245) was tested. Conclusions: Tumor pathologic response during chemo-radiotherapy and the changes of serum VEGF lever could predict curative effects of chemo-radiotherapy in patients with esophageal cancer.

Hydrophobic modified silica/exfoliated graphite nanoplatelets aerogel (M-SiO2/xGnP) were successfullyprepared via surface modification of silica/xGnP alcogel and followed by ambient pressure drying. Afterwards, form-stable PCMs in which capric–palmitic acids eutectic (CA–PA) was confined in theprepared aerogels were obtained by vacuum infiltration. Characterization of the prepared form-stablePCMs revealed that both the hydrophobic modification and the doping of xGnP could effectively improvethe loading of CA–PA in the aerogel. The unmodified silica aerogel could not adsorb CA–PA, while theloading of CA–PA in the surface modified pure silica aerogel supported form-stable PCM and theunmodified silica/xGnP aerogel supported form-stable PCM were 24.2 wt% and 44.4 wt%, respectively. Besides, the hydrophobic modification and the doping of xGnP showed significant synergistic effect. Theloading of CA–PA in the M-SiO2/xGnP supported form-stable PCM (FPCM/xGnP-20-48) could attain78.9 wt% when the M-SiO2/xGnP was obtained by modifying the alcogel with 20 vol% trimethylchlorosilane for 48 h. The FPCM/xGnP-20-48 not only had high latent heat and good thermal reliability,but also exhibited significantly improved thermal conductivity and alleviated supercooling due to theeffective thermal conductive network formed by xGnP and the promoted heterogeneous nucleation ofCA–PA at interfaces with aerogel.

Ye, Ni,Wang, Bin,Quan, Zi-Fang,Cao, San-Jie,Wen, Xin-Tian,Huang, Yong,Huang, Xiao-Bo,Wu, Rui,Ma, Xiao-Ping,Yan, Qi-Gui Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.15
The discovery of long noncoding RNA (LncRNA) changes our view of transcriptional and posttranscriptional regulation of gene expression. With application of new research techniques such as high-throughput sequencing, the biological functions of LncRNAs are gradually becoming to be understood. Multiple studies have shown that LncRNAs serve as carcinogenic factors or tumor suppressors in breast cancer with abnormal expression, prompts the question of whether they have potential value in predicting the stages and survival rate of breast cancer patients, and also as therapeutic targets. Focusing on the latest research data, this review mainly summarizes the tumorigenic mechanisms of certain LncRNAs in breast cancer, in order to provide a theoretical basis for finding safer, more effective treatment of breast cancer at the LncRNA molecular level.

IL-24 Contributes to Neutrophilic Asthma in an IL-17A-Dependent Manner and Is Suppressed by IL-37
Feng Kang-ni,Meng Ping,Zhang Min,Zou Xiao-ling,Li Shuang,Huang Chu-qin,Lai Ke-fang,Li Hong-tao,Zhang Tian-tuo 대한천식알레르기학회 2022 Allergy, Asthma & Immunology Research Vol.14 No.5
Purpose: Neutrophilic asthma is associated with asthma exacerbation, steroid insensitivity, and severe asthma. Interleukin (IL)-24 is overexpressed in asthma and is involved in the pathogenesis of several allergic inflammatory diseases. However, the role and specific mechanism of IL-24 in neutrophilic asthma are unclear. We aimed to elucidate the roles of IL-24 and IL-37 in neutrophilic asthma, the relationships with IL-17A and the mechanisms regulating neutrophilic asthma progression. Methods: Purified human neutrophils were isolated from healthy volunteers, and a cell coculture system was used to evaluate the function of IL-24 in epithelium-derived IL-17A-dependent neutrophil migration. IL-37 or a small interfering RNA (siRNA) targeting IL-24 was delivered intranasally to verify the effect in a murine model of house dust mite (HDM)/lipopolysaccharide (LPS)-induced neutrophilic asthma. Results: IL-24 enhanced IL-17A production in bronchial epithelial cells via the STAT3 and ERK1/2 signaling pathways; this effect was reversed by exogenous IL-37. Anti-IL-17A monoclonal antibodies reduced neutrophil chemotaxis induced by IL-24-treated epithelial cells in vitro. Increased IL-24 and IL-17A expression in the airway epithelium was observed in HDM/LPS-induced neutrophilic asthma. IL-37 administration or IL-24 silencing attenuated neutrophilic asthma, reducing IL-17A levels and decreasing neutrophil airway infiltration, airway hyperresponsiveness, and goblet cell metaplasia. Silencing IL-24 inhibited T-helper 17 (Th17) immune responses, but not Th1 or Th2 immune responses, in the lungs of a neutrophilic asthma model. Conclusions: IL-24 aggravated neutrophilic airway inflammation by increasing epithelium-derived IL-17A production, which could be suppressed by IL-37. Targeting the IL-24/IL-17A signaling axis is a potential strategy, and IL-37 is a potential candidate agent for alleviating neutrophilic airway inflammation in asthma.

In this study, we evaluated the effect of additionof non-volatile compounds (sodium sulfite, tartaric acid,tannin, and glucose) on the rheological properties, releaseof aroma compounds, and color of the red wine. Whiledetermining the rheological properties of the supplementedsamples, non-Newtonian fluidic and shear-thinningbehavior of samples was noticed. The viscosity of thesesamples was found in negative correlation with the dose ofaddition of various non-volatile substances. The aromaprofile of red wine after additions showed the change in therelease of the nine key aroma compounds. Among themethyl hexanoate, phenylethyl alcohol, octanoic acid, diethylsuccinate, and ethyl octanoate were profoundly increased. Further, the color of red wines was improved in the presenceof tartaric acid and tannin. Overall, supplementationof various substances during storage period of three differentwines could enormously affect the sensory characteristicsin a dose dependent manner.

Background: There are few choices for treatment of advanced cancer patients who do not respond to or tolerate conventional anti-cancer treatments. Therefore this study aimed to deploy the benefits and clinical efficacy of continuous dendritic cell-cytokine induced killer cell infusions in such patients. Materials and Methods: A total of 381 infusions (from 67 advanced cases recruited) were included in this study. All patients underwent peripheral blood mononuclear cell apheresis for the following cellular therapy and dendritic cells-cytokine induced killer cells were expanded in vitro. Peripheral blood T lymphocyte subsets were quantified through flow cytometry to address the cellular immunity status. Clinical efficacy and physical activities were evaluated by RECIST criteria and Eastern Cooperative Oncology Group scores respectively. Logistic regression model was used to estimate the association between cellular infusions and clinical benefits. Results: An average of $5.7{\pm}2.94{\times}10^9$ induced cells were infused each time and patients were exposed to 6 infusions. Cellular immunity was improved in that cytotoxic $CD8^+CD28^+$ T lymphocytes were increased by 74% and suppressive $CD8^+CD28^-$ T lymphocytes were elevated by 16% (p<0.05). Continuous infusion of dendritic cells-cytokine induced killer cells was associated with improvement of both patient status and cellular immunity. A median of six infusions were capable of reducing risk of progression by 70% (95%CI 0.10-0.91). Every elevation of one ECOG score corresponded to a 3.90-fold higher progression risk (p<0.05) and 1% increase of $CD8^+CD28^-$ T cell proportion reflecting a 5% higher risk of progression (p<0.05). Conclusions: In advanced cancer patients, continuous dendritic cell-cytokine induced killer cell infusions are capable of recovering cellular immunity, improving patient status and quality of life in those who are unresponsive to conventional cancer treatment.
