  • LncRNA NRON negatively regulates cisplatin-induced cell apoptosis via downregulating miR-31 in esophageal squamous cell carcinomas
    on January 24, 2022 at 12:00 am

    Abstract LncRNA non-coding repressor of NFAT (NRON) can promote bladder cancer and suppress liver cancer, while its role in esophageal squamous cell carcinoma (ESCC) is unknown. We analyzed its involvement in ESCC. NRON and miR-31 expression in plasma before and after cisplatin treatment was detected using RT-qPCR. The correlation between NRON and miR-31 was analyzed by linear regression. Expression of NRON and miR-31 in ESCC cells was also analyzed using RT-qPCR. Overexpression of NRON and miR-31 was achieved in ESCC cells to explore their interaction. Cell apoptosis induced by cisplatin was studied using cell apoptosis assay. NRON was highly expressed in ESCC and further upregulated after cisplatin treatment. MiR-31 was downregulated in ESCC and inversely correlated with NRON. In ESCC cells, NRON overexpression decreased miR-31 expression, while miR-31 failed to alter NRON expression. Cisplatin treatment promoted NRON expression and inhibited miR-31 expression. […]

  • Hemocytic cell line from the moth Glyphodes pyloalis (Lepidoptera: Crambidae) response to essential oils from Artemisia annua (Asterales: Asteraceae)
    on January 24, 2022 at 12:00 am

    Abstract Extensive usage of synthetic chemical pesticides has collateral effects in harming human and animal health and the environment and promoting the development of resistance in pests. The potential of plant compounds as bio insecticides has been described as a promising field of agricultural development. The present study involved the use of Artemisia annua essential oils to evaluate their cytotoxic activities against an established cell line of lesser mulberry pyralid. Five types of hemocytes were recognized (prohaemocytes, plasmatocytes, granulocytes, oenocytoids, and spherulocytes) in the primary cultures maintained in Ex-Cell media with 10% fetal bovine serum (FBS). Artemisia annua essential oils produced noticeable cytotoxicity against the insect cell lines. Applied at a concentration 500 ppm, oils extracted from the vegetative or flowering stages of A. annua produced 71% and 80% cell death, respectively. Nanoemulsions of EOs from the vegetative or […]

  • LncRNA AZIN1-AS1 ameliorates myocardial ischemia–reperfusion injury by targeting miR-6838-5p/WNT3A axis to activate Wnt-β/catenin signaling pathway
    on January 21, 2022 at 12:00 am

    Abstract Myocardial reperfusion, the effective therapy for acute myocardial infarction (AMI), commonly leads to myocardial ischemia/reperfusion (I/R) injury. The effects and functional mechanisms of LncRNA AZIN1-AS1 on myocardial I/R injury in vivo and vitro are not uncovered. In our present study, we established myocardial I/R injury model of mice and H/R injury model of cardiomyocytes and we discovered AZIN1-AS1 was decreased but miR-6838-5p was increased significantly in myocardial tissues injured by I/R treatment and H9c2 cells injured by hypoxia/reoxygenation (H/R) treatment. Silencing AZIN1-AS1 down-regulated cell viability but up-regulated apoptosis rate and CK-MB in addition LDH release of cardiomyocyte under H/R injury. However, overexpression of AZIN1-AS1 recovered abovementioned effects. Additionally, miR-6838-5p was found to be the direct target of AZIN1-AS1 and exhibited negative correlation with AZIN1-AS1. Moreover, miR-6838-5p inhibitor […]

  • Effect of liver receptor homolog-1 on cell apoptosis and steroid hormone secretion on granulosa cells from Hu sheep
    on January 6, 2022 at 12:00 am

    Abstract The apoptosis of granulosa cells can result in follicular atresia, a key process in follicle selection and development. The related molecular mechanisms were explored to study the effects of liver receptor homolog-1 (Lrh-1) on apoptosis, sodium-titanium system, and steroid synthesis of granulosa cells from Hu sheep in vitro. After constructing, designing, and synthesizing the Lrh-1 overexpression vector, liposomes were used to transfect Hu sheep granulosa cells. Thereafter, qRT-PCR and Western blot were used to detect the mechanism of Lrh-1 on the titanium system and steroid synthesis of Hu sheep granulosa cells. The overexpression efficiency was determined by fluorescence 48 h after liposome transfection into the Hu sheep granulosa cells in vitro culture. The transfection efficiency was higher, hence providing a basis for subsequent experiments. However, the protein level and transcriptional level of Lrh-1 significantly increased after transfection with […]

  • Generation of a 3D melanoma model and visualization of doxorubicin uptake by fluorescence imaging
    on January 3, 2022 at 12:00 am

    Abstract Melanoma is the most dangerous type of skin cancer and is responsible for 75% of deaths from skin cancers. For an accurate evaluation of potential treatment efficacy, it is important to use study models as close as possible to the in vivo conditions. A 3D model consisting of B16F10 spheroids was developed using liquid overlay technique on plates coated with 1% agarose, in the presence of 1% methylcellulose and L929-conditioned medium. The model is suitable and can be further used for more complex in vitro drug testing than the classical 2D approach. For exemplification, the behavior of a well-known cytostatic, doxorubicin (DOX), was evaluated in spheroids as compared to classical 2D culture conditions. Fluorescence imaging was used to visualize DOX uptake by B16F10 spheroids at different periods of time. The results showed that a much higher DOX concentration is necessary to produce similar effects compared with the monolayer. The fluorescence images […]

  • Identification of a Cowden syndrome patient with a novel PTEN mutation and establishment of patient-derived induced pluripotent stem cells
    on January 3, 2022 at 12:00 am

    Abstract Cowden syndrome (CS) is an autosomal dominant inherited disorder characterized by multiple hamartomas in various organs such as the mucosa, skin, and gastrointestinal tract. Patients with CS are at high risk for breast and thyroid cancers. Phosphatase and tensin homolog deleted on chromosome 10 (PTEN) is a tumor suppressor gene that negatively regulates the AKT pathway, and PTEN mutations are known to be the major causes of this syndrome. However, the pathogenesis of this syndrome has not been clarified. Here, we present a case of a Japanese woman with multiple oral polyps, breast cancer, and thyroid cancer who was clinically diagnosed with CS. We obtained DNA and RNA samples from the patient’s peripheral blood mononuclear cells (PBMCs) and buccal mucosa tumor. Next-generation sequencing revealed novel germline mutations (c.1020delT and c.1026G > A) in exon 8 of PTEN. Sanger sequencing identified no PTEN transcript from the mutant allele. […]

  • Suppression of PI3K/Akt/mTOR pathway in chrysoeriol-induced apoptosis of rat C6 glioma cells
    on December 14, 2021 at 12:00 am

    Abstract Chrysoeriol, a dietary methoxyflavonoid which is found in tropical medicinal plants, has been shown to have antioxidant, anti-inflammatory, and antineoplastic properties. The present study aimed to investigate the effects of chrysoeriol and its related mechanisms in rat C6 glioma cells. Cell viability in rat C6 glioma cells were measured by MTT assay. The protein expression levels of cleaved caspase-3, caspase-3, pro-apoptotic (Bax), anti-apoptotic protein (Bcl-2), and Annexin V were detected by Western blot analysis and immunocytochemical staining. Results showed that chrysoeriol significantly decreased cell viability and induced apoptosis in rat C6 glioma cells. Chrysoeriol significantly increased the levels of Bax/Bcl-2 ratio and cleaved caspase-3/caspase-3 ratio. Moreover, treatment with chrysoeriol significantly reduced the phosphorylation of PI3K, Akt, and mTOR expression in ratios. These results suggest that chrysoeriol promote […]

  • Lipoxin A4 promotes adipogenic differentiation and browning of mouse embryonic fibroblasts
    on December 1, 2021 at 12:00 am

    Abstract Recently, it has been irrefutably discovered that brown adipocytes dissipate energy as heat and protect against obesity. Researchers make great efforts to explore approaches for its activation. Lipoxin A4 (LXA4) has been proven to reverse adipose tissue inflammation and improve insulin resistance, but its function on brown adipocyte differentiation has been poorly understood, which therefore to be investigated in the present study. Mouse embryonic fibroblasts (MEFs) were induced and differentiated to model brown adipocytes, and treated with LXA4 at 0, 1, 5, and 10 nM for 0–14 d. Afterwards, Oil Red O staining detected lipid droplets. In differentiated MEFs with or without LXA4 (10 nM) treatment, western blot and quantitative real-time polymerase chain reaction (qRT-PCR) assessed adipocyte browning marker uncoupling protein 1 (UCP-1), and brown adipogenesis markers peroxisome proliferator–activated receptor gamma (PPARγ), peroxisome […]

  • Detailed chromosome analysis of wild-type, immortalized fibroblasts with SV40T, E6E7, combinational introduction of cyclin dependent kinase 4, cyclin D1, telomerase reverse transcriptase
    on December 1, 2021 at 12:00 am

    Abstract Cell immortalization enables us to expand the cultured cell infinitely. However, the process of immortalization sometimes changes the nature of the original cell. In this study, we established immortalized embryonic fibroblasts with oncogenic SV40T and human papilla virus–derived E6E7, combinational expression of mutant cyclin-dependent kinase 4 (CDK4), cyclin D1, and telomerase reverse transcriptase (TERT) from identical primary wild-type human embryonic fibroblasts (HE16). After the establishment of immortalized cells, we compared the details of chromosome condition with the G-banding and Q-banding methods. There is no example of detailed analysis so far about chromosome abnormalities, such as trisomy, ring chromosome, reciprocal translocation, and dicentric chromosomes. The detailed chromosome analysis revealed that immortalized cells with SV40T and E6E7 showed intensive chromosome abnormalities, such as gain or loss of the chromosomes all through the […]

  • Epithelial mesenchymal transition regulator TWIST1 transcription factor stimulates glucose uptake through upregulation of GLUT1, GLUT3, and GLUT12 in vitro
    on December 1, 2021 at 12:00 am

    Abstract TWIST1 is a major regulator of epithelial mesenchymal transition process, essential in cancer metastasis. Cancer cells increase glucose uptake capabilities to meet their high energy requirements. In this study, we explored the potential role of TWIST1 on glucose transport into the 293T cells in an insulin-dependent and insulin-independent manner. For this purpose, the ectopic expression of TWIST1 was successfully performed by electroporation. The altered mRNA expressions of GLUT-1, -3, -4, and -12, insulin receptor (InsR), and insulin receptor substrate (IRS)-1 and -2 were assessed in control and TWIST1-overexpressing cells. Glucose uptake rates of the cells were evaluated by fluorometric glucose uptake assay. Our findings showed that the transcriptional expression levels of GLUT-1, -3, and -12 genes were significantly upregulated by TWIST1. However, TWIST1 did not alter the mRNA and protein expressions of the InsR, its substrates (IRS-1 and -2), […]

  • Hypoxia-inducible factor-1α promotes proliferation of airway smooth muscle cells through miRNA-103-mediated signaling pathway under hypoxia
    on December 1, 2021 at 12:00 am

    Abstract The hypoxia-inducible factor-1α (HIF-1α) activated during asthma development plays a causative role in the abnormal proliferation of airway smooth muscle (ASM) cells and consequential airway remodeling. Although the underlying mechanisms of HIF-1α activity have not been fully revealed, HIF-1α-regulated miRNA signaling is considered important for disrupted differentiation and proliferation of local cells in various tissues under inflammation. We aimed to identify the key miRNA signaling involved in HIF-1α regulation of the proliferation of ASM cells. This study was based on primary ASM cells isolated from adult male rats. Three percent O2 and 21% O2 were set as hypoxic and normoxic condition for ASM cell treatment, respectively. Knockdown of HIF-1α was performed through transfection of pSUPER-shHIF-1α plasmid. Overexpression and knockdown of miRNA-103 were performed through transfection of miRNA-103 mimic or inhibitor, respectively. Levels of […]

  • Induction of cardiomyocyte calcification is dependent on FoxO1/NFATc3/Runx2 signaling
    on December 1, 2021 at 12:00 am

    Abstract Cardiovascular disorders (CAVDs) being a major concern over the past several years due to the huge number of morbidity and mortality worldwide, a number of studies have been done on the various aspects of cardiac problems. One of the various CAVDs is cardiovascular calcification. A number of investigations and research work have been done previously on the molecular mechanism of vascular and heart valve calcification but the mechanism of myocardial and cardiomyocyte calcification has remained uninvestigated. A number of case studies have shown the presence of calcific deposits in the myocardial/ventricular region of the heart in fetal condition as well as in individuals of different ages but no detailed studies have been done yet. In this study, we have mainly investigated the role of Forkhead box transcription factor FoxO1 and nuclear factor of activated T-cells NFATc3 in cardiomyocyte calcification. Our studies in H9c2 cardiomyocytes show that calcific […]

  • Nucleoporin 37 promotes the cell proliferation, migration, and invasion of gastric cancer through activating the PI3K/AKT/mTOR signaling pathway
    on December 1, 2021 at 12:00 am

    Abstract Gastric cancer is a kind of malignant tumor in the world. Emerging studies have proved the regulatory role of nucleoporin 37 in the development of several malignant tumors. However, the potential effect of NUP37 in gastric cancer is still unclear. In this study, we searched for the Cancer Genome Atlas analysis to explore the potential correlation between NUP37 and gastric cancer. Then, we analyzed NUP37 expression in gastric cancer tissues and cell lines. After constructing a NUP37-silenced model in NCI-N87 cells and a NUP37-overexpressed model in MKN45 cells, we evaluated the role of NUP37 in cell proliferation, migration, and invasion as well as its underlying mechanism. TCGA analysis showed that NUP37 expression was highly expressed in stomach adenocarcinoma, which showed a lower survival rate than normal samples. Moreover, NUP37 was found to be highly expressed in gastric cancer tissues and cell lines. Functionally, NUP37 deficiency promoted […]

  • Cedrol alleviates the apoptosis and inflammatory response of IL-1β-treated chondrocytes by promoting miR-542-5p expression
    on December 1, 2021 at 12:00 am

    Abstract Cedrol has been shown to exert anti-tumor, anti-inflammatory, and anti-oxidative effects, but its role in osteoarthritis (OA) is unclear. This study aimed to explore the effect of cedrol in OA. Chondrocytes were isolated from newborn rats and cultured in Dulbecco’s modified Eagle’s medium (DMEM). Then, Alcian blue staining was used to identify the chondrocytes. IL-1β and cedrol were used to treat chondrocytes. Cell viability and apoptosis were measured by MTT and flow cytometry assays, respectively. The expressions of miR-542-5p, miR-26b-5p, miR-572, miR-138-5p, miR-328-3p, miR-1254, Bcl-2, Bax, iNOS, COX-2, and MMP-13 were detected by quantitative reverse transcription polymerase chain reaction (qRT-PCR) or western blot. NO and PGE2 levels were detected by ELISA. All the cells extracted from the newborn rats were dyed blue, indicating that the cells were chondrocytes. IL-1β could reduce the viability and promote apoptosis and inflammatory response […]

  • 1α,25-(OH)2-D3 promotes the autophagy during osteoclastogenesis by enhancing RANKL-RANK-TRAF6 signaling
    on October 1, 2021 at 12:00 am

    Abstract As the active form of vitamin D3, 1α,25-(OH)2-D3 promotes receptor activator for nuclear factor-κB ligand (RANKL)-induced autophagy in osteoclast precursors (OCPs). However, the relationship between 1α,25-(OH)2-D3 and RANKL signaling is still unknown. This study aimed to explore whether 1α,25-(OH)2-D3 regulates OCP autophagy and osteoclastogenesis through RANKL signaling. Our results showed that 1α,25-(OH)2-D3 directly decreased OCP autophagy while significantly enhancing the ability of RANKL to promote OCP autophagy. Moreover, 1α,25-(OH)2-D3 not only promoted the expression of key signaling proteins in OCPs induced by RANKL but also enhanced the coimmunoprecipitation levels of RANK and TRAF6. Notably, 1α,25-(OH)2-D3 significantly enhanced the autophagic activity and osteoclast differentiation of RANK-positive OCPs but did not affect the autophagic activity or osteoclast differentiation of RANK-negative OCPs. More importantly, 1α,25-(OH)2-D3 had no […]

  • Vascular endothelial growth factor ameliorated palmitate-induced cardiomyocyte injury via JNK pathway
    on October 1, 2021 at 12:00 am

    Abstract Enhanced apoptosis of cardiomyocytes in suffering overloaded saturated fatty acids (SFAs) can result in myocardial infarction and cardiac dysfunction. The function of vascular endothelial growth factor (VEGF) in cardiomyocyte protection was not clearly described. To investigate the preservative effects of VEGF sensitization on ceramide-mediated programmed cell death of cardiomyocytes, palmitate-induced injury in H9c2 cells was established as an in vitro model. Results revealed that 0.5 mM palmitate application effectively led to debased viability and activated apoptotic factors. A significant time-dependent relation between PAL and cardiomyocyte injury was observed. The apoptosis rate was increased greatly after 16 h of treatment with 0.5 mM PAL. In addition, cell viability was restored by VEGF overexpression during treatment with 0.5 mM PAL. Reduced apoptosis rate and expression of caspase 3, Bax, and NF-κB p65 were observed in this process, while […]

  • Prolonged hypoxia switched on cancer stem cell-like plasticity in HepG2 tumourspheres cultured in serum-free media
    on October 1, 2021 at 12:00 am

    Abstract Tumour hypoxia drives resistance and aggressiveness, and in large part, contributes to treatment failure thereby causing cancer-related deaths. The rapid and uncontrolled tumour growth develops not only a hypoxic niche but also a nutrient-deprived condition due to insufficient blood supply; together, these create a stressful tumour niche, further promoting higher aggressiveness and resistance features of cancer. However, how cellular responses in the prolonged stress is associated with cancer stem cells (CSCs), which is linked to these features, remains unclear. Here, we established HepG2 tumoursphere culture in a hypoxic and serum-free condition that recapitulated differential responses to prolonged tumour growth pressures, evident by their progressive changes in the morphology of tumoursphere formation over a course of 15-day culture. HepG2 tumourspheres formed larger sphere sizes of > 200 μm in hypoxic conditions, concomitant with higher […]
