Objective. To investigate the expression of miR-338-3p in nasopharyngeal carcinoma (NPC) and its relationship with STAT3 mRNA expression as well as their relationship with clinical pathological parameters and prognosis of patients. Methods. From September 2016 to September 2018, 71 patients with NPC were selected as the NPC group, and 71 samples of NPC tissues were collected during the operation. A total of 23 patients who underwent biopsy due to chronic nasopharyngitis were selected as the control group and 23 nasopharyngeal mucosal tissues were collected. The expressions of miR-338-3p and STAT3 mRNA in nasopharyngeal tissue of two groups were detected by real-time quantitative PCR, and the relationship between the two was analyzed. To collect clinical data of NPC patients and analyze the relationship between the expressions of miR-338-3p and STAT3 in NPC tissues and clinical pathological parameters of the patients, we followed up the patients with nasopharyngeal carcinoma for three years to observe the relationship between miR-338-3p, STAT3, and the prognosis of the patients. Results. The relative expression levels of miR-338-3p in nasopharyngeal tissues of the NPC group and the control group were 0.39 ± 0.05 and 1.01 ± 0.09, respectively ( P  < 0.05). The relative expression levels of STAT3 mRNA in nasopharyngeal tissues of the NPC group and the control group were 3.82 ± 0.21 and 1.04 ± 0.11, respectively ( P  > 0.05). miR-338-3p was negatively correlated with the relative expression of STAT3 mRNA in nasopharyngeal carcinoma (r = 0.038, P  > 0.05). The expression of miR-338-3p was related to the age of the patient, clinical TNM stage, T stage, and distant metastasis (all P  < 0.05). STAT3 expression was correlated with clinical TNM stage, T stage, and distant metastasis in our patient ( P  < 0.05). The expressions of miR-338-3p and STAT3 in nasopharyngeal carcinoma tissues from different gender, histological type, N stage, M stage, and degree of differentiation showed no statistical differences ( P  > 0.05). The survival rate of the group with low miR-338-3p expression was significantly lower than that of the group with high miR-338-3p expression ( P  > 0.05). The survival rate of patients with the high STAT3 expression group was significantly lower than that of patients with the low STAT3 expression group ( P  > 0.05). Conclusion. There is a negative correlation between the low expression of miR-338-3p and the high expression of STAT3 in NPC, which are all related to the TNM stage, T stage, and prognosis of the patient.

Paraquat (PQ) is one of the most widely used herbicides in the world and can cause pulmonary fibrosis in the cases with intoxication. Losartan, an angiotensin II type 1 receptor antagonist, has beneficial effects on the treatment of fibrosis. The aim of this study was to examine the effect of losartan on pulmonary fibrosis in PQ-intoxicated rats. Adult male Sprague Dawley rats ( n = 32, 180–220 g) were randomly assigned to four groups: (i) control group; (ii) PQ group; (iii) PQ + losartan 7d group; and (iv) PQ + losartan 14d group. Losartan treatment (intragastrically (i.g.), 10 mg/kg) was performed for 7 and 14 days after a single i.g. dose of 40 mg/kg PQ. All rats were killed on the 16th day, and hematoxylin–eosin and Masson’s trichrome staining were used to examine lung injury and fibrosis. The levels of hydroxyproline and transforming growth factor β1 (TGF-β1), matrix metallopeptidase 9 (Mmp9), and tissue inhibitor of metalloproteinase 1 (TIMP-1) messenger RNA (mRNA) expression and relative expression levels of collagen type I and III were also detected. PQ caused a significant increase in hydroxyproline content, mRNA expression of TGF-β1, Mmp9, and TIMP-1, and relative expression levels of collagen type I and III (  p < 0.05), while losartan significantly decreased the amount of hydroxyproline and downregulated TGF-β1, Mmp9, and TIMP-1 mRNA and collagen type I and III expressions (  p < 0.05). Histological examination of PQ-treated rats showed lung injury and widespread inflammatory cell infiltration in the alveolar space and pulmonary fibrosis, while losartan could markedly reduce such damage and prevent pulmonary fibrosis. The results of this study indicated that losartan could reduce lung damage and prevent pulmonary fibrosis induced by PQ.

<b><i>Objectives:</i></b> to investigate the expression levels of 1,25(OH)<sub>2</sub>D<sub>3</sub> in the peripheral blood from patients with myasthenia gravis (MG) and to correlate levels with retinoid-related orphan receptor γt (RORγt) and forkhead or winged-helix transcription factor 3 (Foxp3) mRNA expression. <b><i>Methods:</i></b> Sixty-seven patients with MG were enrolled in the experimental group, and 50 normal subjects were selected as the control group. The expression levels of 1,25(OH)<sub>2</sub>D<sub>3</sub> and RORγt and Foxp3 mRNAs were measured in the serum of the 2 patient groups and the relationship between factors were correlated with the severity score of MG. The relationship between the levels of 1,25(OH)<sub>2</sub>D<sub>3</sub> and the relative expressions of RORγt and Foxp3 mRNAs was determined. <b><i>Results:</i></b> There were no differences between groups regarding patient’s baseline data. 1,25(OH)<sub>2</sub>D<sub>3</sub> and RORγt and Foxp3 mRNAs are differentially expressed in the MG group and the control group (<i>p</i> &#x3c; 0.05). QMG score is negatively correlated with the expression level of peripheral blood 1,25(OH)<sub>2</sub>D<sub>3</sub> and Foxp3 mRNA (<i>r</i> = −0.797, −0.543; <i>p</i> &#x3c; 0.01) and positively correlated with the relative expression level of RORγt mRNA (<i>r</i> = 0.539; <i>p</i> &#x3c; 0.01). 1,25(OH)<sub>2</sub>D<sub>3</sub> expression level was negatively correlated with the relative expression of RORγt mRNA (<i>r</i> = −0.559; <i>p</i> &#x3c; 0.01) and positively correlated with the relative expression of Foxp3 mRNA (<i>r</i> = 0.390; <i>p</i> &#x3c; 0.01). <b><i>Conclusions:</i></b> The levels of 1,25(OH)<sub>2</sub>D<sub>3</sub> were shown to be lower in patients with MG compared to normal controls. The observed low levels of 1,25(OH)<sub>2</sub>D<sub>3</sub> may lead to changes in the expression of RORγt and Foxp3 mRNAs involved in MG.

Abstract Background: Present study was to investigate the relative expression and prognostic performance of protein phosphatase magnesium/manganese-dependent 1D (PPM1D) in bladder cancer.Methods: Quantitative real-time polymerase chain reaction (qRT-PCR) assay was performed to examine the relative expression of PPM1D mRNA in bladder cancer tissues and adjacent normal bladder tissues. The associations of PPM1D mRNA expression with clinicopathological features and the prognostic value were statistically analyzed via Chi-square test, Kaplan-Meier method and Cox regression analysis.Results: In comparison to adjacent normal tissues, PPM1D mRNA expression was obviously increased in bladder cancer tissues (P<0.001). Abnormal PPM1D expression was remarkably related to histological grade (P=0.017), TNM stage (P=0.032) and lymph nodes metastasis (P=0.035). Kaplan-Meier method showed that a close relationship was found between PPM1D expression and overall survival time (P=0.000). Multivariate analysis indicated that PPM1D expression (P=0.000, HR=3.530, 95%CI: 2.001-6.228) was a promising independent predictor for the prognosis of bladder cancer patients, as well as TNM stage (P=0.042, HR=1.768, 95%CI: 1.021-3.062).Conclusion: Taken together, our data showed that the potential performance of PPM1D as a prognostic biomarker and therapeutic target of bladder cancer.

Background Clear cell renal cell carcinoma (ccRCC) is a common urological disease. Expression of the protein tyrosine phosphatase 12 gene ( PTPN12) is decreased in many cancers; however, the relationship between PTPN12 gene function and renal cancer remains unclear. Methods We detected PTPN12 protein expression in ccRCC and corresponding normal tissues from 64 patients with ccRCC by immunohistochemistry, and relative PTPN12 mRNA levels by real-time quantitative polymerase chain reaction. The relationships between the relative expression levels of PTPN12 mRNA and the patients’ clinical data were analyzed. Results PTPN12 protein and mRNA expression levels were significantly lower in ccRCC compared with the corresponding normal tissues. The mRNA expression levels in the ccRCC and corresponding normal tissues from the 64 patients with ccRCC were 0.459±0.445 and 1.001±0.128, respectively, compared with the control (glyceraldehyde 3-phosphate dehydrogenase). There was a significant correlation between relative expression of PTPN12 mRNA in ccRCC tissues and tumor diameter and clinical stage. Conclusion The expression levels of PTPN12 protein and mRNA were significantly lower in ccRCC tissues compared with normal tissues. The role of PTPN12 may provide new insights and evidence to aid the diagnosis and targeted therapy of ccRCC.

Purpose. This study aimed to evaluate the clinical efficacy of using expression levels ofCCL24(eotaxin-2) mRNA on the ocular surface as a biomarker in patients with vernal keratoconjunctivitis (VKC) and atopic keratoconjunctivitis (AKC).Methods. Eighteen patients with VKC or AKC (VKC/AKC group) and 12 control subjects (control group) were enrolled in this study. The VKC/AKC clinical score was determined by objective findings in patients by using the 5-5-5 exacerbation grading scale. All subjects underwent modified impression cytology and specimens were obtained from the upper tarsal conjunctiva. Expression levels ofCCL24(eotaxin-2) mRNA on the ocular surface were determined using real-time reverse transcription polymerase chain reaction.Results. The VKC group was divided into two subgroups, depending on the clinical score: the active stage subgroup with 100 points or more of clinical scores and the stable stage subgroup with 100 points or less.CCL24(eotaxin-2) mRNA expression levels in the active VKC/AKC stage subgroup were significantly higher than those in the stable VKC/AKC subgroup and the control group. Clinical scores correlated significantly withCCL24(eotaxin-2) mRNA expression levels in the VKC group.Conclusions.CCL24(eotaxin-2) mRNA expression levels on the ocular surface are a useful biomarker for clinical severity of VKC/AKC.

A thorough understanding of the processes modulating the innate and acquired immune response to Mycobacterium tuberculosis (M.tb) infection in the context of gene expression is still a scientific and diagnostic problem. The study was aimed to assess IL-18, IL-18 binding protein (IL-18BP), IL-18R, IFN-γ, and IL-37 mRNA expression in patients with active tuberculosis (ATB) and healthy volunteers with latent M.tb-infection (LTB) or M.tb-uninfected healthy controls (Control). The relative mRNA expression was assessed in the buffy coat blood fraction using the qPCR method. In total, 97 BCG-vaccinated Polish adults were enrolled in the study. The relative expression of IL-18 and IL-18BP mRNA was significantly elevated in the ATB and LTB groups. In ATB, but not LTB individuals, the overexpression of IL-18 and IL-18BP, as well as a significant increase in IFN-γ mRNA expression, might be considered as a manifestation of active tuberculosis disease. No statistically significant differences were observed in the IL-37 mRNA expression among the studied groups. Particularly noteworthy is the outstanding reduction in the relative expression of IL-18R mRNA in the LTB group as compared to the ATB and Control group. Reduced expression of IL-18R in LTB group may, at least partially, prevent the development of a pathological inflammatory reaction and promote the maintenance of homeostatic conditions between host immunity and M.tb.

The objective of this article is to study the effect of inhibiting phosphatase and tensin homolog deleted chromatosome 10 gene on phosphoinositide 3-kinase/protein kinase B ( Akt)/Forkhead homeobox O3a signaling pathway in human nasopharyngeal carcinoma HK-1 cells. Nasopharyngeal carcinoma HK-1 cell lines were divided into PTEN gene interference group (siPTEN), nonspecific small interfering RNA group (siNC), empty vector group (Vector), and no transfection control group (Normal). The mRNA and protein expression levels of PTEN, PI3K, p-Akt, and FoxO3a were detected by real-time fluorescence quantitative polymerase chain reaction and Western blot. Immunofluorescence was used to detect the subcellular localization of PTEN, PI3K, p-Akt, and FoxO3a in HK-1 cells. The proliferation of HK-1 cells was detected by MTT assay, and the apoptosis of HK-1 cells was detected by flow cytometry. Compared with the siNC group, the expression levels of PTEN, FoxO3a messenger RNA, and protein in the siPTEN group were significantly decreased ( P < .05), while the expression levels of PI3K, p-Akt messenger RNA, and protein were significantly increased ( P < .05). The growth rate of HK-1 cells in the siPTEN group was significantly higher than the siNC group ( P < .05), while the apoptosis rate was significantly lower than that of the siNC group ( P < .05). Small interfering RNA can inhibit the expression of PTEN in HK-1 cells, and PTEN can participate in the development of NPC by affecting PI3K/Akt/FoxO3a signaling pathway.

Abstract Immune thrombocytopenic purpura (ITP) is an autoimmune disease characterized by platelet destruction resulting from autoantibodies against self-antigens and T-cell mediated cytotoxicity. Toll-like receptors (TLRs) are pattern recognition receptors important in mediating the immune response and their activation can lead to production of cytokines. Recent data suggest that TLR2 and TLR4 are crucial for the production of inflammatory cytokines and play central role in autoimmune diseases, yet little is known about their roles in ITP. Here we examined the gene expressions of TLR2 and TLR4 in ITP patients. We hypothesize that significant differences will exist between pre-treatment and post-treatment in ITP patients with similar changes reflected in the plasma concentration of cytokines. Total RNA was extracted from mononuclear cells obtained from 12 ITP patients and 15 healthy subjects. TLR2 and TLR4 mRNA expression levels were analyzed using a quantitative real-time PCR method and their protein expressions were validated by western blot. Plasma concentrations of cytokines IL-2, IFN-γ and TNF-α were measured by ELISA. Correlation analyses were carried out between the mRNA expression levels of TLR2 or TLR4 and the plasma levels of IL-2, IFN-γ and TNF-α. The gene expression of TLR2 and TLR4 were significantly increased in ITP patients comparing to healthy control group (p < 0.05 and p < 0.01, respectively). In addition their mRNA expression levels were decreased back into normal range after remission in 8 patients (p > 0.05, compared to healthy control group). Significantly positive correlations were found between the TLR2 mRNA expression level and the plasma concentration of IFN-γ or TNF-α (R = 0.75, p < 0.05; R = 0.83, p < 0.05, respectively). Changes in the gene expression of TLR4 and in the plasma concentration of IFN-γ or TNF-α were also significantly correlated (R = 0.82, p < 0.05; R = 0.88, p < 0.05, respectively). Directional changes in TLR2 / TLR4 and IFN-γ /TNF-α expression were concordant. However, there was no correlation found between TLR2 / TLR4 and IL-2. Differences in TLR2 and TLR4 expression strongly correlated with changes in IFN-γ and TNF-α suggest that the increased gene expressions of TLR2 and TLR4 in ITP patients may contribute to the pathophysiological progression of this disease by increasing the secretion of IFN-γ and TNF-α. Additional studies need to be performed to further clarify the role of TLRs -cytokines pathway in ITP.

To explore the effect of Eimeria tenella infection on the cytokines gene expression and IgA production in the spleen of chickens, the morphological characteristics of the spleen were observed through optical and transmission electron microscopy. The IgA production was determined through immunohistochemistry. The mRNA expression levels of splenic cytokines were detected through real-time PCR. Compared to the control group, along with the infection of E. tenella, the splenic lymphocytes exhibited irregular and cracked membranes, mitochondria swelled even vacuolization, the IgA expression in spleen tissue was decreased by 55.57% (p lessthan 0.01). Likewise, the mRNA expression levels of IL-2 and IL-1â decreased by 40% (plessthan 0.01) and 43% p lessthan 0.05), respectively. By contrast, the IL-6, IFN-g and IL-10 levels increased by 158% (p lessthan 0.01), 464% (p lessthan 0.05) and 379% p lessthan 0.01), respectively. These results indicated that the spleen implement an important function in the antagonism of E. tenella, which suggest a new strategy to control coccidiosis by improving the peripheral immunity of chickens.

Endurance exercise induces specific skeletal muscle adaptation by increasing mitochondrial oxidative phosphorylation eficiency and mitochondrial biogenesis. Many previous studies suggesting both PGC-1a and COX IV as a potential biomarker of skeletal muscle adaptation induced by exercise. But most of them only studied the effect of long-term endurance exercise, whereas the effect of short-term exercise remains unclear. To investigate short-term physiological adaptation induced by endurance exercise on expression of COX IV and PGC-1a mRNA in rat skeletal muscle. Twenty healthy male Wistar rats (Rattus norvegicus) aged 10-11 weeks old were used in this experiment. Rats were randomly assigned into 4 groups based on the time period of exercise: 1) control (C; n=5), 2) three days of exercise (E3; n=5), 3) six days of exercise (E6; n=5), 4) fifteen days of exercise (E15; n=5). The exercise groups were run at 20m/s for 30 minutes on the rat treadmill and the stationary control group was only placed inside treadmill with the machines turned off. On the last day of exercise, the rats were sacrificed then RNA from skeletal muscle was extracted. COX IV and PGC-1a mRNA expressions were measured by Reverse Transcriptase PCR. The results showed that there were statistically significant differences of PGC-1a mRNA expression levels in both soleus (F(3,16)=3.740, ps=0.033) and gastrocnemius (F(3,16)=3.969, pg=0.027) muscles. The COX IV mRNA expression levels in soleus (F(3,16)=3.801, ps=0.031) and gastrocnemius (F(3,16)=5.429, ps=0.009) muscles were also significantly increased. There were significant increases of PGC-1a and COX IV expressions in fifteen days of exercise group compared to control group in both muscles. Short-term endurance exercise induced mitochondrial biogenesis marker and mitochondrial activity marker by increasing the PGC-1a and COX IV mRNA expression levels in rat skeletal muscle significantly following the time periods of exercise.
