Abstract
Background The purpose of this study was to construct a nomogram based on classical parameters and immunohistochemical markers to predict the recurrence of early low-risk endometrial cancer patients. Methods A total of 998 patients with early low-risk endometrial cancer who underwent primary surgical treatment were enrolled (668 in the training cohort, 330 in the validation cohort). Prognostic factors identified by univariate and multivariate analysis in the training cohort were used to construct the nomogram. Prediction performance of the nomogram was evaluated using the calibration curve, concordance index (C-index), and the time-dependent receiver operating characteristic curve. The cumulative incidence curve was used to describe the prognosis of patients in high-risk and low-risk groups divided by the optimal risk threshold of the model. Results In the training cohort, grade ( P = 0.040), estrogen receptor ( P < 0.001), progesterone receptor ( P = 0.001), P53 ( P = 0.004), and Ki67 ( P = 0.002) were identified as independent risk factors of recurrence of early low-risk endometrial cancer, and were used to establish the nomogram. The calibration curve showed that the fitting degree of the model was good. The C-indexes of training and validation cohorts were 0.862 and 0. 827, respectively. Based on the optimal risk threshold of the nomogram, patients were split into a high-risk group and a low-risk group. The cumulative incidence curves showed that the prognosis of the high-risk group was far worse than that of the low-risk group ( P < 0.001). Conclusion This nomogram, with a combination of classical parameters and immunohistochemical markers, can effectively predict recurrence in early low-risk endometrial cancer patients.

Abstract
BACKGROUND Gestational trophoblastic disease (GTD) is a group of interrelated but distinct diseases and has a serious impact on the reproductive health of women. To analyze the expression of Nanog in GTD and to evaluate its potential to predict the development of gestational trophoblastic neoplasia (GTN). METHODS The study included 41 normal first-trimester placentas matched by gestational age to 53 regressed-hydatidiform-moles (rHMs), 56 malignant-HMs (mHMs) and 17 choriocarcinomas (CCAs) and evaluated the Nanog expression by immunohistochemistry. The chi-square test, ANOVA, Fisher's exact test and logistic regression were performed to assess the Nanog expression and clinical prognostic factors in GTD. RESULTS Compared to normal placenta levels, the Nanog expression was increased in GTD samples (p < .05). In HMs, Nanog expression was positively correlated with serum β-hCG levels,uterine size and theca-lutein cysts (p < .05). Compared with the low-risk metastatic group (Federation of Gynecology and Obstetrics (FIGO) score ≤ 6), the high-risk metastatic group (FIGO score >7) had higher Nanog expression (p = .030). Moreover, logistic regression analysis showed that the positive expression of Nanog had the highest risk of developing into GTN (OR = 4.764, p < .001). CONCLUSIONS Nanog is an independent predictor of clinical outcomes. It can also be a reliable predictor for GTN development from GTD.

Abstract
Objective In this study, 345 patients with endometrial carcinoma (EC) were selected to investigate the correlation between ER/PR status and the EC disease-free survival (DFS) rate. Methods The intensity and proportion of tumor cell expression of estrogen receptors and progesterone receptors (ER/PR) status of 345 postoperative tumor specimens in ECs were independently assessed semi-quantitatively by two pathologists using immunohistochemistry, the summed score ranged from 0 to 8 points was worked out by adding proportion score and intensity score based on the breast cancer hormone receptor immunohistochemical Allred scoring system. The association between DFS in ECs and ER/PR expression (intensity, proportion and summed score) was assessed using Cox regression analysis. Gene expression data were obtained from The Cancer Genome Atlas research network (TCGA). Results According to inclusion criteria, 201 type I and 144 type II EC patients were enrolled in this study. In the univariate analysis of type I endometrial carcinoma, the intensity, proportion and summed score of ER/PR status were significantly correlated with DFS. After adjusting for factors known to significantly impact survival, the influence of ER/PR status on DFS is generally decreased but the correlation is still significant. In the univariate analysis of type II endometrial carcinoma, the intensity, proportion and summed score of ER/PR status were significantly correlated with DFS. After adjusting for factors known to significantly impact survival, the influence of ER status on DFS is generally decreased, but the correlation is still significant, the effect of PR expression on DFS is not statistically significant. Conclusion Higher ER/PR expression status was associated with better DFS in patients with type I endometrial cancer after adjusting for known factors that significantly affect survival. In patients with type II endometrial cancer, patients with positive ER expression were significantly associated with better DFS. However, the effect of PR expression on DFS was not statistically significant.

Abstract
Background Lung adenocarcinoma has surpassed lung squamous cell carcinoma as the most common type of non-small cell lung cancer. In this study, we had tested the biological role of TRIM2 in lung adenocarcinoma. Methods TRIM2 abundance in clinical tissues and six cell lines were examined with quantitative real-time PCR test (qRT-PCR) and western blot. TRIM2 overexpression treated H322 cells and TRIM2 knockdown treated A549 cells were used to study cell proliferation, migration, colony formation, invasion, and the expression of epithelial mesenchymal transformation (EMT) biomarkers. Moreover, ubiquitination related Snail1 degradation were studied with qRT-PCR and western blot. The relationships between TRIM2 and Snail1 were investigated with western blot, co-immunoprecipitation, migration, and invasion. Results TRIM2 was highly expressed in lung adenocarcinoma tissues. TRIM2 overexpression and knockdown treatments could affect cell proliferation, colony formation, migration, invasion, and the expression of EMT associated biomarkers. Moreover, TRIM2 can regulate the ubiquitination related Snail1 degradation. In addition, TRIM2 can regulate Snail1 degradation in lung adenocarcinoma via ubiquitination pathway. TRIM2 could promote the proliferation, migration, and invasion of lung adenocarcinoma. Meanwhile, TRIM2 can deubiquitinate and stabilize Snail1 protein, which play important role in the function of lung adenocarcinoma. Conclusion A high TRIM2 expression could be detected in lung adenocarcinoma tissues and cells. TRIM2 could aggravate cell proliferation, invasion, and migration in colorectal cancer by regulating Snail1 ubiquitylation degradation. Our results could provide detailed information for further studies in lung adenocarcinoma.

Abstract
In addition to its critical role during pregnancy, human chorionic gonadotropin (hCG) has been shown to be expressed by various tumor types. Recent studies have similarly documented the presence of the luteinizing hormone (LH)/hCG receptor (LHCGR) in a variety of nongonadal organs; however, its clinicopathological significance in ovarian cancer remains unclear. The present study used a combination of immunohistochemical, real-time PCR, and western blot analyses to examine hCG and LHCGR expression in normal and cancerous tissues collected from patients with epithelial ovarian cancer (EOC). hCG and LHCGR expression levels were resultantly shown to be significantly increased and decreased in cancerous versus normal (or benign) ovarian tissues, respectively (P < 0.05), and both expression pattern changes were associated with more advanced tumor stages and a higher rate of metastasis. Furthermore, patients with tumors with high or low levels of hCG and LHCGR, respectively, experienced a worse overall survival (OS) rate than those with low hCG or high LHCGR expression levels (P < 0.05). In fact, hCG and LHCGR expression levels were independent prognostic factors of patient OS (P < 0.05) for EOC. Collectively, these findings indicate that hCG and LHCGR expression pattern changes are associated with EOC occurrence and progression. Thus, hCG and LHCGR represent promising potential targets to improve the diagnosis, treatment, and prognosis of patients with EOC.

Abstract
Background High-grade serous ovarian cancer (HGSOC) represents most of the ovarian cancers and accounts for 70%-80 % of related deaths. The overall survival of HGSOC has not been remarkably improved in the past decades, due to the tumor dissemination in peritoneal cavity and invasion of adjacent organs. Therefore, identifying molecular biomarkers is invaluable in helping predicting clinical outcomes and developing targeted chemotherapies. Although there have been studies revealing the prognostic significance of protein tyrosine phosphatase L1 (PTPL1) in breast cancer and lung cancer, its involvement and functions in HGSOC remains to be elucidated. Methods We retrospectively enrolled a cohort of HGSOC patients after surgical resection. And analyzed the mRNA and protein levels of PTPL1 in tissue samples. Results We found that PTPL1 presented a lower expression in HGSOC tissues than in adjacent normal ovarian tissues. Besides, the PTPL1 level was negatively correlated with tumor stage, implying its potential role as a tumor suppressor. Univariate and multivariate analyses identified that patients with higher PTPL1 showed a better overall survival compared to those with lower PTPL1 expression. In addition, cellular experiments confirmed the role of PTPL1 in suppressing tumor proliferation and invasion. Furthermore, we demonstrated that PTPL1 negatively regulated phosphorylation of tyrosine 42 on IκBα (IκBα-pY42). To our knowledge, this is the initial finding on PTPL1 targeting IκBα-pY42 site. Finally, our data indicated that PTPL1 suppressed tumor progression by dephosphorylating IκBα-pY42, which stabilized IκBα and attenuated nucleus translocation of NF-κB. Conclusion Our study revealed a tumor-suppressing role of PTPL1 in HGSOC by targeting IκBα.
