development of resistance to endocrine therapy, such as tamoxifen, remains a tricky clinical problem during the treatment of breast cancer. Accumulating evidence suggested that dysregulation of long noncoding (lnc_RNAs contributes to the development of tamoxifen resistance. In the current study, via screening, cytoskeleton regulator RNA (cYTOR) was identified as the most significantly elevated lncRNA in the established tamoxifen resistant McF7 cell lines (McF7/TAM1 and McF7/TAM2) compared with the parental McF7 cells (McF7-P). The ccK-8 assay indicated that silencing of cYTOR increased the sensitivity of McF7/TAM1 and McF7/TAM2 to tamoxifen treatment. Using bioinformatic analysis, it was predicted that microRNA (miR)-125a-5p might bind to cYTOR and the expression of miR-125a-5p was negatively correlated with cYTOR in the tumor tissues of breast cancer. In addition, RT-qPcR and dual luciferase assays validated that cYTOR directly repressed miR-125a-5p expression in breast cancer cells. Through regulation of miR-125a-5p, cYTOR elevated serum response factor (SRF) expression and activated Hippo and mitogen associated protein kinase signaling pathways to promote breast cancer cell survival upon tamoxifen treatment. In the collected tumor tissues of breast cancer in the present study, high expression of cYTOR was detected in tissues from patients with no response to tamoxifen compared with those from patients who were not treated with tamoxifen. A positive correlation between cYTOR and SRF mRNA expression was observed in tissues collected from patients with breast cancer. In conclusion, the results of the present study demonstrated a pivotal role of cYTOR in mediating tamoxifen resistance in breast cancer.
Human papillomavirus (HPV) infection which continues to be the most common sexually transmitted disease, has been identified as a major risk factor for cervical cancer. Therefore, it is very important to understand and grasp the distribution of HPV in Chinese population, and make the foundation for the development of cervical cancer vaccine in China. An extensive search strategy was conducted in multiple literature databases. All retrieved studies were screened by October 31, 2018. The prevalence of HPV infection was analyzed using random effects model. A total of 68 studies satisfied the inclusion criteria for our study. The national overall prevalence of HPV infection was 15.54% (95% CI: 13.83%‐17.24%). we also performed subgroup analysis by age, geographic location, level of economic development, HPV assay method, and type of HPV infection. The top 5 common HPV types detected in general population, were HPV 16 (3.52%, 95% CI: 3.18%‐3.86%), 52 (2.20%, 95% CI: 1.93%‐2.46%), 58 (2.10%, 95% CI: 1.88%‐2.32%), 18 (1.20%, 95% CI: 1.05%‐1.35%), and 33 (1.02%, 95% CI: 0.89%‐1.14%). Except for the higher prevalence of HPV infection in 2009 and 2010, the prevalence of HPV infection in other years changed little, ranged from 13.2% to 17.4%. HPV type in Chinese women was quite distinctive. HPV infection played a critical role in the occurrence of cervical cancer, understanding the distribution of HPV type and performing the HPV type testing had important clinical value for colposcopy referral and increasing the detection rate. Therefore, our findings could provide evidence for cervical cancer screening and vaccine, in order to reduce the burden of cervical cancer.
Goenka's 10-day Vipassana course is a widespread mindfulness course rooted in traditional Buddhism. Awareness and equanimity are two abilities cultivated in this course that are not featured in modern mindfulness-based psychotherapies and thereby not adequately measured by current mindfulness scales. The present article analyzed the Philadelphia Mindfulness Scale (PHLMS; Cardaciotto et al. in Assessment 15(2):204-223, 2008) and revised it into a short version to avoid confusion when measuring awareness and equanimity. Empirical data obtained using Chinese university students and Chinese Buddhists showed that the psychometric properties of the original version of the PHLMS had low factor loading on some items and that the short version had improved psychometric properties, especially for Buddhists. The short PHLMS also exhibited reasonable relationships with emotional outcomes and meditation practices among Buddhists. Implications for the future application of the PHLMS among Buddhists were also discussed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
