LncRNA PTCSC3 (PTCSC3) inhibits thyroid cancer cervical carcinoma and glioma, while its roles in gastric cancer are unknown. Studies have reported that HULC could serve as a potential biomarker for the diagnosis and prognosis of gastric cancer (GC). Our study aimed to investigate the potential interaction between PTCSC3 and HULC in gastric cancer. This study enrolled 77 gastric cancer patients at the First Affiliated Hospital of Anhui Medical University from January 2016 to January 2018. RT-qPCR was performed to analyze gene expression levels. Cell transfections were carried out to evaluate gene interactions. Transwell assays and wound healing assays were used to analyze the effects of transfection on cell invasion and migration. Western blotting was also used to illustrate the possibility that lncRNA PTCSC3 and lncRNA HULC negatively affected each other through WNT signal path. We showed that PTCSC3 was downregulated in tumor tissues of gastric cancer patients in comparison to that in adjacent healthy tissues, and an inverse correlation between the expression levels of PTCSC3 and AJCC stage was observed. LncRNA HULC (HULC) was upregulated in tumor and inversely correlated with PTCSC3 in tumor tissues. Overexpression of PTCSC3 mediated the inhibition of HULC, while overexpression of HULC also mediated the inhibition of PTCSC3. PTCSC3 inhibited, while HULC promoted invasion and migration of gastric cancer cells. In addition, overexpression of HULC attenuated the effects of overexpression of PTCSC3. However, overexpression of PTCSC3 showed no significant effects on cell proliferation. We also found that PTCSC3/HULC affected each other to regulate cell invasion and migration through the Wnt/β-catenin signaling. Therefore, overexpression of PTCSC3 inhibited the invasion and migration of gastric cancer cells, and the function of PTCSC3 is associated with HULC.Therefore, overexpression of PTCSC3 inhibited the invasion and migration of gastric cancer cells, and the function of PTCSC3 is associated with HULC. To evaluate whether the depth of response (DepRe) and early tumor shrinkage (ETS) are predictive factors of clinical outcomes in HER2-positive metastatic breast cancer (mBC) patients treated with trastuzumab. We performed a retrospective study of 100 HER2-positive mBC patients who received trastuzumab combined with chemotherapy as first-line treatment. ETS and DepRe were calculated. We employed Youden's index to determine the optimal cutoff value of ETS and DepRe for predicting progression-free survival (PFS) and overall survival (OS). We used Kaplan-Meier analysis, Log-rank tests, and Cox proportional hazards regression models to evaluate the impacts of ETS and DepRe on clinical outcomes. The optimal cutoff values were 30% for ETS and 40% for DepRe; ETS and DepRe were observed in 51.0% (51/100) and in 56.0% (56/100) of patients, respectively. Both ETS≥30% and DepRe≥40% were significant tumor-size metrics for predicting PFS (ETS median 1.43 vs 0.69 years, hazard ratio [HR] = 0.384; 95% confidence interval [CI] 0.245 to 0.601; =0.000030; DepRe median 1.43 vs 0.59 years, HR = 0.390; 95% CI 0.250 to 0.609; =0.0000034), but only DepRe≥40% was a significant predictor for OS (median 4.02 vs 3.07 years, HR = 0.484; 95% CI 0.255 to 0.919; = 0.027). Multivariate analyses also identified DepRe as an independent prognostic factor for PFS (HR = 0.52; 95% CI 0.29 to 0.93; = 0.028) and OS (HR=0.37; 95% CI0.15 to 0.90; = 0.029). ETS≥30% and DepRe≥40% were significant predictors of better clinical outcomes in mBC patients treated with first-line trastuzumab-based chemotherapy. Further validation in prospective trials with larger patient populations is needed.ETS≥30% and DepRe≥40% were significant predictors of better clinical outcomes in mBC patients treated with first-line trastuzumab-based chemotherapy.

Ethiopia launched the human papilloma vaccination for the first time, with the support of the Global Alliance for Vaccine and Immunization (GAVI) in 2018. Therefore, the aim of this study was to assess the acceptability of the human papillomavirus vaccine and associated factors among parents of daughters in Gondar town, Northwest Ethiopia. A community-based cross-sectional study with a total sample of 946 study participants was conducted in Gondar town from April to May 2019. The study participants were selected using a multistage sampling technique from parents having a daughter of 9-17 years age. Data were collected using an interviewer-administered questionnaire. The data were entered into EpiData version 4.2 and exported to STATA version 14 for analysis. Variables having a p-value of <0.2 and <0.05 in the bivariable and multivariable logistic regression were considered as a statisticalls high and was significantly associated with the level of knowledge about cervical cancer, the attitude towards HPV vaccination, and the wealth status of the households. Therefore, community education on cervical cancer and its prevention is crucial to increase awareness and acceptance as well. Lung tumors and normal lung tissues show large differences in epigenetic modification which can affect the chromosome structure and expression of genes. Baxdrostat ic50 However, the epigenetic reprogramming in lung adenocarcinoma remains unclear. With the bioinformatics analysis, we found that some activated super-enhancers (SEs) only appear in lung adenocarcinoma cells, and 781 abnormal activated super-enhancers (AASEs) were found. Not only are the traditional oncogenes found to be activated by AASEs, such as and , but also some new genes were activated by AASEs, which probably contributes to the carcinogenic process in lung cancer. The enrichment analysis of the genes activated by AASEs shows that the glycolysis process and cell proliferation were enhanced and the apoptotic process was negatively regulated. Two AASEs were separately knockout by CRISPR/Cas9 in A549, PC-9, and H1299 cell lines and the expression of target genes decreased. The motif of , , , , , , and was enriched in AASEs, supporting that the chromosome structure changed and these transcription factors would be the master regulators on the formation of AASEs.
