RESUMO

BACKGROUND: Maternal parenting self-efficacy plays a critical role in facilitating positive parenting practices and successful adaption to motherhood. The Perceived Maternal Parenting Self-Efficacy Scale (PMPS-E), as a task-specific measure, confirms its psychometric properties in cultural contexts. Compared with other tools, the advantages of the PMPS-E are as follows: (i) specific context or time period during the lifespan of a child, (ii) explicitly assess parenting self-efficacy across a diverse enough range of parenting tasks or activities during the perinatal/postnatal period and (iii) having robust psychometric properties. The aim of this study was to translate and determine the psychometric properties of the PMPS-E among Chinese postpartum women (C-PMPS-E). METHOD: The cross-cultural adaptation process followed Beaton et al.'s intercultural debugging guidelines. A total of 471 women were included to establish the psychometric properties of the C-PMPS-E. Mothers were asked to complete the C-PMPS-E, Edinburgh Postnatal Depression Scale (EPDS), the Generalized Anxiety Disorder-7 (GAD-7) and several demographic questions. The psychometric testing of the C-PMPS-E was established through item analysis, construct validity and internal consistency reliability. RESULTS: Item analysis showed that the critical ratios of all items were greater than 3 between the low-score group and high-score group, and all item-total correlation coefficients were greater than 0.4. The fit indices showed that the original correlated four-factor model of C-PMPS-E was observed to be an excellent fit to the data. The PMPS-E was negatively correlated with the EPDS and GAD-7 demonstrating its discriminant validity. As expected, no significant correlation was found between PMPS-E total or subscale scores and mothers' age. In addition, statistically significant differences for parity were detected for C-PMPS-E total and subscale scores with multipara having higher scores. This was taken as further evidence of the scale known-groups discriminant validity. In terms of internal consistency, the Cronbach's alpha of the C-PMPS-E total scale was 0.950, and subscales ranged from 0.76 to 0.89. Furthermore, a ROC curve analysis was conducted to establish the ability of the C-PMPS-E to distinguish between symptoms of depression and symptoms of anxiety. A cut-off value of 55 was identified that resulted in good specificity and fair sensitivity. CONCLUSION: The C-PMPS-E is a reliable and valid tool to assess maternal parenting self-efficacy in a Chinese context.

RESUMO

Objective: To analyze the potential value of paraspinal nerve block (PVB) in percutaneous nephrolithotomy (PCNL) and to compare it with general anesthesia and epidural anesthesia. Methods: 120 patients undergoing PCNL surgery in Shanghai Jiao Tong University Affiliated Sixth People's Hospital from January 2021 to June 2022 were selected and divided into PVB anesthesia group, general anesthesia group, and epidural anesthesia group according to different anesthesia methods, with 40 cases in each group. The anesthesia index (anesthesia operation time, anesthetic effect time, anesthesia time), the vital signs (heart rate, mean arterial pressure), postoperative pain [visual analog scale (VAS)], stress response index (cortisol and noradrenaline), the incidence of adverse reactions (nausea and vomiting, lethargy, dizziness, skin itching, bradycardia) were compared among the three groups. Results: The operation time of the anesthesia in the PVB anesthesia group was 5.72±1.25, which was significantly lower than that in the the general (7.95±1.15) and epidural anesthesia groups(8.23±1.43), and the differences were statistically significant (P = .000). The time of onset of anesthesia in the PVB anesthesia group was 6.63±1.87, which was significantly lower than that in the the general (9.84±2.41) and epidural anesthesia groups(10.14±2.89), and the differences were statistically significant (P = .000).The heart rate during percutaneous puncture and intraoperative lithotripsy in the PVB anesthesia group was statistically lower than in the general and epidural anesthesia groups (P < .05). The mean arterial pressure 20 minutes after anesthesia and at the end of operation in the PVB anesthesia group was higher than that in the general anesthesia group, and the mean arterial pressure during percutaneous puncture and intraoperative lithotomy was lower than that in the general anesthesia group (P < .05). The VAS scores of the PVB anesthesia group at 2, 6, 12, 24, and 48 hours after the operation were lower than those of general and epidural anesthesia groups (P < .05). The incidence of adverse reactions was 5.00% (2/40) in the PVB anesthesia group and 35.00% (14/40) in the general anesthesia group, which was lower than that of 27.50% (11/40) in the epidural anesthesia group. (P < .05). Conclusion: The potential value of PVB in PCNL is high is better than that of general anesthesia and epidural anesthesia, anesthesia can shorten operation time and work time, extend the time of anesthesia to maintain, and be helpful to the intraoperative vital signs in patients with stable, mild postoperative pain and stress, low incidence of adverse reactions, efficacy and safety are good, can be introduced.

RESUMO

BACKGROUND: Copine 1 (CPNE1) acts as a promoter in the progression of many kinds of cancers with the exception of pancreatic cancer (PC). This research is designed to probe the function of the CPNE1-tumor necrosis factor receptor-associated factor 2 (TRAF2) axis in PC. METHODS: In vivo and in vitro models of PC were constructed, and a series of biological function tests, including MTT [3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide], colony formation, flow cytometry, and immunohistochemistry, were performed. RESULTS: The level of CPNE1 elevated dramatically in PC cells. Downregulation of CPNE1in PC cells resulted in the inhibition of colony formation and proliferation. In addition, the silencing of CPNE1 induced the G1/S arrest and apoptosis in PC cells. Additionally, TRAF2 positively interacted with CPNE1 in PANC cells. CPNE1 silencing also inhibited the growth of tumors in in vivo mouse models. Functional experiments revealed that the anti-tumor effect of CPNE1 silencing was counteracted by TRAF2 overexpression, and the tumor-promoting effect of TRAF2 overexpression was reversed by CPNE1 silencing. CONCLUSIONS: In summary, our findings indicate that the silencing of the CPNE1-TRAF2 axis restrains PC development.

RESUMO

BACKGROUND: Increasing evidence show that women across the world face unacceptable mistreatment during childbirth. Person-centered maternity care is fundamental and essential to quality of healthcare services. The aim of this study was to translate and determine the psychometric properties of the Person-Centered Maternity Care (PCMC) Scale among Chinese postpartum women. METHODS: A cross-sectional study was conducted among 1235 post-partum women in China. The cross-cultural adaptation process followed the Beaton intercultural debugging guidelines. A total of 1235 women were included to establish the psychometric properties of the PCMC. A demographic characteristics form and the PCMC were used for data collection. The psychometric properties of the PCMC were evaluated by examining item analysis, exploratory factor analysis, known-groups discriminant validity, and internal consistency. RESULTS: The number of extracted common factors was limited to three (dignity & respect, communication & autonomy, supportive care), explaining a total variance of 40.8%. Regarding internal consistency, the Cronbach's alpha coefficient and split-half reliability of the full PCMC score were 0.989 and 0.852, respectively. CONCLUSIONS: The Chinese version of the PCMC is a reliable and valid tool to assess person-centered care during childbirth in China.

RESUMO

BACKGROUND: The optimal treatment for some symptomatic, benign osteopathy lesions is yet to be identified. PURPOSE: To investigate the clinical efficiency of cementoplasty in managing symptomatic, benign osteopathy. MATERIAL AND METHODS: Between June 2006 and January 2020, we retrospectively enrolled 31 patients (10 men, 21 women; mean age = 46.5 ± 16.6 years; age range = 20-85 years), accounting for 34 treatment sites, who underwent percutaneous osteoplasty (14 treatment sites) and percutaneous vertebroplasty (20 treatment sites) with digital subtraction angiography (DSA) or DSA combined with computed tomography (CT). All the participants experienced different degrees of clinical symptoms with benign osteopathy lesions. The technical success of the procedure and occurrence of complications were recorded. Follow-up examinations were conducted to assess the treatment outcome using the MacNab criteria. RESULTS: All the participants had a diagnosis of benign osteopathy lesions before or after the cementoplasty. Surgery was successfully completed in all patients. Cement distributions were diffuse and homogeneous, with the complication of cement leakage occurring in 17.6% (6 of 34) of the lesions. The leakage occurred in the intervertebral disc (n = 1), the intra-articular space (n = 1), and the surrounding soft tissue (n = 4). Analysis of the treatment outcome using the MacNab criteria revealed that all patients showed improvement in their clinical symptoms to some extent and in the quality of life. CONCLUSION: Cementoplasty is an effective treatment for symptomatic, benign osteopathy, with the advantage of favorable clinical outcomes, and low complication rate.

RESUMO

Background: Gliomas are the most common and most malignant primary tumors of the adult central nervous system, but their etiology and pathogenesis remain unclear. This study was aimed at investigating the expression and function of lncRNA PDCD4-AS1 in glioma and elucidating the mechanism by which PDCD4-AS1 regulates the biological features of glioma. Method: The expression of PDCD4-AS1 was determined by bioinformatic analysis and qRT-PCR assay. PDCD4-AS1 was knocked down in glioma cells using siRNA transfection. The functional analysis of cells was conducted using CCK-8 proliferation, cell migration, and invasion assays, as well as cell cycle analysis. An in vivo tumorigenesis assay was performed to investigate the role of PDCD4-AS1 knockdown in glioma tumor growth. We performed bioinformatic analysis, RNA pull-down, and luciferase reporter assays to investigate the downstream targets of PDCD4-AS1. A rescue experiment was then performed to confirm the regulating mechanism. Results: PDCD4-AS1 was found to be significantly upregulated in glioma patients' tumor tissues and cell lines. The silencing of PDCD4-AS1 inhibited glioma cell proliferation, invasion, migration, and induced cell cycle arrest. In vivo experiments showed that silencing PDCD4-AS1 inhibited glioma tumor growth. An investigation of the underlying mechanism suggested that PDCD4-AS1 positively regulated METTL7B expression by sponging miR-30b-3. Both the knockdown of miR-30b-3p and the overexpression of METTL7B could, respectively, reverse the malignant phenotype of cells affected by silencing PDCD4-AS1. Conclusion: These results demonstrate that PDCD4-AS1 exerted an oncogenic role by regulating the miR-30b-3p/METTL7B axis.

RESUMO

Isoquercitrin is a natural flavonoid quercetin with anti-inflammatory, anti-anaphylactic, antiviral, and anticancer activities. Here, we investigated the effect of isoquercitrin on immunogenic cell death (ICD) of gastric cancer (GC). The effect of isoquercitrin on GC cell lines (AGS and HGC-27) was evaluated using cell counting kit-8 assays, colony formation assays, Annexin V/PI apoptosis detection kit, western blot analysis, JC-1 staining, immunofluorescence assays, and enzyme-linked immunosorbent assay. Isoquercitrin at doses greater than 20 µM had significant inhibitory effects on the survival of GC cell lines, including HGC-27, AGS, MKN-45, and SNU-1. Isoquercitrin treatment decreased GC cell colony formation in a dose-dependent manner and induced apoptosis accompanied by downregulation of BCL-2 and upregulation of BAX, cleaved caspase-3, and caspase-12. In addition, isoquercitrin promoted the disruption of mitochondrial membrane potential in GC cells. The GC cell surface levels of calreticulin (CRT) and extracellular levels of CRT, ATP, and HMGB1 were enhanced by treatment with isoquercitrin. The protein levels of HMGB1, HSP70, and HSP90 were upregulated by isoquercitrin in a dose-dependent manner. Moreover, the endoplasmic reticulum (ER) stress inhibitor 4-phenylbutyrate reversed isoquercitrin-induced ICD in GC cells. Overall, our data suggested that isoquercitrin induces ER stress and ICD in GC cells. Isoquercitrin may be a candidate anticancer drug for the treatment of GC.

RESUMO

BACKGROUND: Renal cell carcinoma (RCC) is a common malignant tumor of the urinary system with a high recurrence rate and easy metastasis. Current clinical drugs for renal cell carcinoma include immunotherapies and targeted drugs. Axitinib is a clinically targeted drug for treating renal cell carcinoma, which has shortcomings such as unstable efficacy and easy drug resistance. Therefore, this study aims to determine whether embelin can enhance the sensitivity of renal cancer cells to axitinib and explore its regulatory pathways. METHODS: The enhancing effect of embelin on axitinib was detected using MTT, crystal violet staining, and annexin VFITC staining in two renal cancer cell lines. Western blot was performed to detect the expression of autophagy-related proteins under different conditions. Bioinformatic tools were used to predict the pathways through which embelin may act on renal cancer cells, and pharmacological methods were used to verify the results. RESULTS: Embelin enhanced the sensitivity of renal cancer cells to axitinib in the following aspects: enhancing the inhibition of cell proliferation by axitinib, and the induction of cell apoptosis. HIF was a potential pathway for embelin's action. After IOX2 regulated the HIF-1α pathway, the enhancing effect of embelin on axitinib was weakened. Moreover, after PT2977 regulated the HIF-2α pathway, the enhancing effect of embelin on axitinib was weakened. CONCLUSIONS: Embelin enhanced the sensitivity of A498 and 786-O renal cancer cells to axitinib by inhibiting the HIF pathway.

RESUMO

BACKGROUND: The great economic and social changes have resulted in the prevalence of mental disorder increasing year by year in China. Mental health medical service resources of China are significantly insufficient. The program of Transfer Training for psychiatrist was launched in China in October 2015. Thousands of physicians completed the transfer training and obtained certificates. To date, there is little evidence to identify the status and related factors of clinical competence among scope-of-practice transfer psychiatrists in China. PURPOSE: This study aimed to investigate the status and related factors of clinical competence among scope-of-practice transfer psychiatrists of Sichuan Province, China. PATIENTS AND METHODS: The sample was composed of 291 physicians who certificated the transfer training. Data were collected between September and November 2021, using self-made questionnaire with a total of 22 items to record demographic characteristics, practice status and workplace of participants. Descriptive statistics analysis, independent sample T-test, one-way ANOVA, Spearman rank correlation, and multiple regression analysis were used to analyze the data. RESULTS: The clinical competence of participants score was (8.02 ± 1.48). Significant differences were found in clinical competence scores among: the subgroups of practice category, reasons for attending in the transfer training for psychiatrists, whether transfer to/ add mental health practice registration, whether engage in mental / psychological work after training, whether the level of transfer training meeting participants' job needs, whether the level of transfer training meeting their theoretical learning needs, whether the level of transfer training meeting their clinical practice needs, salary change compared with pre-training, whether join in continuing education after training, whether wanted to join in continuing education after training, whether the workplace before training has mental / psychological department, whether the workplace after training has mental / psychological department, institutional nature, institutional level and institutional affiliation. Multiple regression analysis identified that level of transfer training meeting participants' job needs, level of transfer training meeting their clinical practice needs, Whether the workplace before training has mental / psychological department, whether wanted to join in continuing education after training, institutional nature were the contributors of clinical competence. CONCLUSION: The study demonstrated that clinical competence of scope-of-practice transfer psychiatrists needed to be improved. Whether workplace has mental/psychological departments was an important factor of clinical competence. Besides, interest of physicians is another crucial factor for their clinical competence. The continuing education of those psychiatrists may be one effective measure considering their factual working conditions.

RESUMO

Tripartite motif-containing protein 11 (TRIM11) and family with sequence similarity 46B (FAM46B) have been demonstrated to play roles in prostate cancer development, but their function in paclitaxel resistance remains unclear. The role of TRIM11 and FAM46B in paclitaxel resistance in prostate cancer was estimated. The paclitaxel-resistant cells were established with gradually increasing concentrations of paclitaxel in prostate cancer cells. The sensitivity to paclitaxel of established cells was assessed by the value of the median inhibitory concentration in the presence of 0-1000 nM paclitaxel. The expression level of TRIM11 and FAM46B was evaluated by real-time quantitative polymerase chain reaction. The proliferation, migration, and invasion of established cells were evaluated by CCK8 and Tran-swell assay. TRIM11 was upregulated in paclitaxel-resistant cells and promoted the proliferation, migration, and invasion of established cells. The significant downregulation of FAM46B was observed in paclitaxel-resistant cells. Although the overexpression of FAM46B suppressed the viability and metastasis of paclitaxel-resistant cells, which was reversed by the upregulation of TRIM11. Both the knockdown of TRIM11 and overexpression of FAM46B could enhance paclitaxel sensitivity of established resistant cells. The promoted effect of FAM46B overexpression was alleviated by the elevation of TRIM11. TRIM11 could improve the sensitivity to paclitaxel of resistant prostate cancer cells via regulating FAM46B.

RESUMO

To investigate the effect of long noncoding RNA ST8SIA6-AS1 on the epithelial-to-mesenchymal transition (EMT) and angiogenesis of pituitary adenoma and its possible mechanism. The expression levels of ST8SIA6-AS1 and HOXA9 in noninvasive pituitary adenoma and invasive pituitary adenoma were detected using qRT-PCR. sh-ST8SIA6-AS1 transfection silenced the expression of ST8SIA6-AS1 in GH3 and GTI-1 cells. The effects of ST8SIA6-AS1 on the proliferation, invasion, angiogenesis, and EMT of GH3 and GTI-1 pituitary adenoma cells were detected. The migration ability of cells was detected through scratch assay. Dual luciferase analysis verified the targeting relationship between ST8SIA6-AS1 and miR-5195-3p. ST8SIA6-AS1 and HOXA9 were highly expressed in invasive pituitary adenoma. In pituitary adenomas, miR-5195-3p directly targeted HOXA9. miR-5195-3p is the target gene of ST8SIA6-AS1. ST8SIA6-AS1 knockdown inhibited the proliferation, invasion, angiogenesis, and EMT of pituitary adenoma. HOXA9 expression mediates the biological effect of ST8SIA6-AS1. ST8SIA6-AS1 targets miR-5195-3p to regulate the expression of HOXA9 and promote the EMT of pituitary adenomas.

RESUMO

This study is aimed at investigating the effect and mechanism of long noncoding RNA (lncRNA) KCNQ1OT1 on pituitary adenoma (PA). The KCNQ1OT1 expression in invasive and noninvasive PA tissues was detected by real-time fluorescence quantitative polymerase chain reaction (qPCR). The effects of KCNQ1OT1 on the proliferation of PA cells, namely, GH3 and HP75, were detected by CCK-8 experiment. The Transwell assay detected the effect of KCNQ1OT1 on the invasion of GH3 and HP75 cells. The effect of KCNQ1OT1 on the clonal formation ability was detected by clonal formation experiment. The double luciferase reporter assay and the miRNA pull down assay verified the binding of KCNQ1OT1 to miR-140-5p. Meanwhile, the regulatory effect of miR-140-5p on RAB11A was verified. qPCR results showed that KCNQ1OT1 was significantly increased in invasive PA compared with noninvasive PA tissues. Knockdown KCNQ1OT1 inhibited PA cell stemness, angiogenesis, and EMT. In addition, knockdown KCNQ1OT1 inhibited the proliferation, invasion, and clonal formation of PA. miR-140-5p is the target gene of KCNQ1OT1. miR-140-5p targets RAB11A directly. RAB11A can mediate the biological effects of KCNQ1OT1. Meanwhile, lncRNA KCNQ1OT1 can promote the EMT and cellular stemness of PA. Its mechanism of action is realized by inhibiting miR-140-5p. This result can provide a molecular basis for the further study of PA.

RESUMO

This study aimed to determine the apoptosis and autophagy-inducing mechanism of atractylodin in human breast cancer MCF-7 cells. The molecular mechanism of anticancer activity of atractylodin was confirmed by assessing the levels of reactive oxygen species (ROS) level, lipid peroxidation (LPO), antioxidants activity, dual staining, and comet assay. Moreover, cleaved caspases 3, 8, and 9, and signaling proteins, such as p53, Bcl-2, and Bax, phosphatidylinositol-3-kinase/protein kinase B/mammalian target of rapamycin(P13K/Akt/mTOR), LC3I and LC3II, and beclin-1 were analyzed. In MCF-7 cells treated with atractylodin, the concentration-dependent toxicity, increased LPO, increased production of ROS, and decreased activity of superoxide dismutase, catalase, and glutathione peroxidasewere observed. In MCF-7 cells, atractylodin administration decreased Bcl-2 expression while activating the expression of p53, Bax, cleaved caspase-3, caspase-8, and caspase-9 apoptotic members. Furthermore, atractylodin blocked the P13K/Akt/mTOR signaling pathway, increased the conversion of LC3I to its lipidated form of LC3II, and increased beclin-1 expression, whereas downregulated the p62 expression in MCF-7 cells. As a result, altering apoptotic and autophagy-related biomarkers, atractylodin triggered apoptosis and autophagy in MCF-7 cells. As a result, atractylodin could be utilized to treat human breast cancer after the proper clinical trial.

RESUMO

This study aimed to investigate the effects of luteolin on colorectal cancer (CRC) and explore its underlying mechanism. HCT-116 and HT-29 cells were treated with luteolin, cisplatin, or selumetinib. The cell survival, cell proliferation, apoptosis and cell cycle distribution, and DNA damage were detected using Cell Counting Kit-8, colony formation, flow cytometry, and immunofluorescence staining analysis, respectively. Western blotting was used to detect the expression of apoptosis-related, cycle-related, DNA-damage-related, and mitogen-activated protein kinase (MAPK) pathway-related proteins. Luteolin showed inhibitory effects on cellular growth by reducing cell survival and proliferation, inducing apoptosis and DNA damage, and arresting the cell cycle in a concentration-dependent manner in HCT-116 and HT-29 cells. Meanwhile, luteolin increased the expression of pro-apoptotic proteins, p-CHK1 (central to the induction of cell cycle arrest), and DNA excision repair protein and decreased anti-apoptotic proteins, G2-M phase-related proteins, and DNA repair proteins. The combination of cisplatin and luteolin significantly decreased cell survival and increased the apoptosis rate of HCT-116 and HT-29 cells compared with cisplatin alone. Bioinformatic analysis using the Comparative Toxicogenomics Database and STITCH and MalaCards databases showed that the MAPK pathway is involved in the pharmacology of luteolin. Furthermore, western blotting demonstrated that luteolin plays an inhibitory role by suppressing the MAPK signaling pathway in CRC, which is enhanced when combined with selumetinib. Luteolin can also prevent tumourigenesis in CRC in vivo. In conclusion, luteolin suppressed cell proliferation, blocked the cell cycle, and induced DNA damage and apoptosis progression in CRC cells by mediating the MAPK pathway.

RESUMO

BACKGROUND: Neurovascular-related genes have been implicated in the development of cancer. Studies have shown that a high expression of neuropilins (NRPs) promotes tumourigenesis and tumour malignancy. METHOD: A multidimensional bioinformatics analysis was performed to examine the relationship between NRP genes and prognostic and pathological features, tumour mutational burden (TMB), microsatellite instability (MSI), and immunological features based on public databases and find the potential prognostic value of NRPs in pancancer. RESULTS: Survival analysis revealed that a low NRP1 expression in adrenocortical carcinoma (ACC), cervical squamous cell carcinoma and endocervical adenocarcinoma (CESC), low-grade glioma (LGG), and stomach adenocarcinoma (STAD) was associated with poor prognosis. A high NRP2 expression in bladder urothelial carcinoma (BLCA), kidney renal papillary cell carcinoma (KIRP), and mesothelioma (MESO) was associated with poor prognosis. Moreover, NRP1 and NRP2 were associated with TMB and MSI. Subsequent analyses showed that NRP1 and NRP2 were correlated with immune infiltration and immune checkpoints. Genome-wide association analysis revealed that the NRP1 expression was strongly associated with kidney renal clear cell carcinoma (KIRC), whereas the NRP2 expression was closely associated with BLCA. Ultimately, NRP2 was found to be involved in the development of BLCA. CONCLUSIONS: Neurovascular-related NRP family genes are significantly correlated with cancer prognosis, TME, and immune infiltration, particularly in BLCA.

RESUMO

OBJECTIVE: Increased dependence on glycolysis is a known element of cancer. This study was designed to examine critical glycolysis components including transcription factor MYC and its downstream target lactate dehydrogenase A (LDHA), potential upstream regulators of glycolysis such as family with sequence similarity 46 member B (FAM46B), and the impact of the abundance of these proteins on apoptosis and glycolysis in prostate cancer. MATERIALS AND METHODS: A total of 70 primary prostate cancer patient samples were compared to normal tissues for FAM46B and LDHA expression and the corresponding patients' survival was monitored for 60 months. Prostate cancer cell lines were employed for protein expression manipulation, glucose uptake and LDH assays, and apoptosis measurements. A xenograft mouse model was used to quantify the role of FAM46B and LDHA on tumor growth in vivo. RESULTS: FAM46B expression was reduced in prostate tumor tissue compared to normal tissue and prostate cancer patients who expressed low amounts of FAM46B had shortened average lifespans compared to those who expressed higher amounts of FAM46B (p=0.008). FAM46B overexpression reduced glucose uptake, decreased LDH activity, and induced apoptosis in prostate cancer cell lines while FAM46B shRNA increased MYC levels in a non-malignant prostate cell line (P69). Conversely, forced expression of LDHA in LNCaP cells produced an increase in glycolysis markers with a corresponding decrease in apoptosis. FAM46B-overexpressing xenografts had starkly blunted growth which was restored with co-overexpression of LDHA. CONCLUSION: FAM46B plays a central role in regulating glycolysis and apoptosis in prostate cancer and operates through the regulation of LDHA via MYC. FAM46B's keystone status in prostate cancer makes it a potential, robust biomarker for prostate cancer prognosis and a promising therapeutic target.

RESUMO

Phase transition occurring during cycling plays a fundamentally important role in the cycling performance of nickel-rich cathodes. Here, splitting of two O3 phases, rather than the often observed O1 phases in the conventional LiCoO2 electrode, was discovered in LiNi0.85Co0.10Mn0.05O2 at a high-voltage region (>4.6 V). Such degradation could be mitigated via Al doping.

RESUMO

Plant bio constituents have the ability to prepare nanoparticles, and usually, plant polyphenols are tested to reduce sodium selenite to selenium nanoparticles (SeNPs). In this work, we showed the biosynthesis of SeNPs using Ocimum tenuiflorum leaf extract. The as obtained SeNPs were in the size range of 15-20 nm and spherical in shape. Also, TEM microscopic images represented the aggregation of crystal structures as extracellular deposits. Moreover, scanning electron microscopy was performed to examine the chemical transition of calcium oxalate (CaC2O4) crystal's shape and structure due to the influence of SeNPs. SeNPs inhibited the aggregation and growth of CaC2O4 monohydrate crystals and hence the prepared SeNPs could have important prospects in medical and pharmaceutical applications as a potential inhibitor of CaC2O4 urinary stones.

RESUMO

BACKGROUND: Renal cancer represents about 3 % of all human cancers. Clear cell renal cell carcinoma (ccRCC) is the main type of renal cancer. Methionine sulfoxide reductase B3 (MSRB3) is a protein repair enzyme that specifically catalyzes the reduction of methionine-R-sulfoxide residues and has an antioxidant function. However, MSRB3's role in ccRCC is still obscure. METHODS: Immunohistochemical staining and Real-time PCR were used to compare the expression level of MSRB3 in ccRCC tissues and adjacent tissues. Western blot was used to detect the expression of MSRB3 in cell lines. Chi-square test were applied to evaluate the potential of MSRB3 to function as a cancer biomarker. RNA interference was used to inhibit MSRB3 expression in ccRCC cells, followed by detecting cell proliferation, apoptosis, migration and invasion. The markers of endoplasmic reticulum stress were then detected by western blot. RESULTS: In this study, we validated that MSRB3 was significantly up-regulated in ccRCC samples and cell lines. It was also demonstrated that the up-regulation of MSRB3 was associated with several clinicopathologic features. Knockdown of MSRB3 remarkably arrested the proliferation, migration and invasion, while promoted apoptosis, and induced the changes of markers of endoplasmic reticulum stress. CONCLUSION: In conclusion, we demonstrated that MSRB3 was an oncogene of ccRCC associated with patients' pathological characteristics and modulated endoplasmic reticulum stress of cancer cells.

RESUMO

BACKGROUND AND OBJECTIVES: Osteoarthritis (OA) is a widespread degenerative joint disease characterized by articular cartilage degradation and is the leading cause of physical disability. Noncoding RNAs, especially long noncoding RNAs (lncRNAs) and microRNAs, are involved in the degradation of the chondrocyte extracellular matrix (ECM) in patients with OA. The present study was aimed to investigate the effects of lncRNA and miR-22 on the degradation of the chondrocyte ECM and underlying mechanisms. METHODS: To simulate conditions found in OA, primary cultured chondrocytes were treated with IL-1, TGF-ß, or sb525334. Real-time PCR and Western blot analysis were performed to detect expressions of miR-22, lncRNA-TM1P3, ALK1, MMP13, pSMAD1/5, SMAD1, and pSMAD5. Small interfering RNAs and a miR-22 mimic or inhibitor were utilized to determine lncRNA-TM1P3 knockdown and miR-22 overexpression or inhibition. RESULTS: The lncRNA-TM1P3 significantly upregulated in patients with OA, accompanied by the downregulation of miR-22 and upregulation of pSMAD1/5 and MMP13, which ultimately resulted in the degradation of the chondrocyte ECM in patients with OA. Bioinformatics analysis predicted miR-22 as a target of both lncRNA-TM1P3 and MMP13. The lncRNA-TM1P3 knockdown significantly increased the expression of ALK1, a corresponding increase in ECM degradation was observed by affecting the phosphorylation of SMAD1/5 and the expression of MMP13, which did not affect the expression of ALK1. CONCLUSIONS: These findings demonstrated that the lncRNA-TM1P3/miR-22/TGF-ß signaling/MMP13 axis is involved in the degradation of chondrocyte ECM in patients with OA, which could provide novel therapies for OA treatment.
