The incidence and mortality rates of lung cancer remain high, making it the leading cause of cancer-related deaths. In women, the predominant histological subtype is lung adenocarcinoma, commonly associated with epidermal growth factor receptor (EGFR) mutations, and EGFR-tyrosine kinase inhibitors (EGFR-TKIs) can significantly improve patient prognosis. Metastasis of primary lung cancer to the endometrium is extremely rare and is often misdiagnosed as a primary reproductive system tumor, and its occurrence indicates poor prognosis. This article reports a case of an advanced lung adenocarcinoma patient with EGFR mutation, who developed abnormal vaginal bleeding after EGFR-TKIs treatment failure, and biopsy confirmed endometrial metastasis. A review of similar cases is also presented.

Objective To investigate the relationships of the expression of microRNA-487a-3p (miR-487a-3p) and A kinase-interacting protein 1 (AKIP1) mRNA in the endometrial cancer (EC) tissue with the patient survival within 5 years after surgery. Methods The EC tissue and adjacent normal tissue samples were collected from 130 EC patients who underwent surgical treatment at the Fourth Hospital of Shijiazhuang from September 2016 to April 2019.qRT-PCR was employed to determine the expression levels of miR-487a-3p and AKIP1 mRNA.The patients were followed up for 5 years after surgery to record the survival status.After removal of the patients who missed follow-up,78 surviving patients were recorded as the EC survival group,and 34 deceased patients were recorded as the EC death group.The dual luciferase reporter gene assay was conducted to verify the targeting relationship between miR-487a-3p and AKIP1 mRNA.Comparison was conducted for the expression levels of miR-487a-3p and AKIP1 mRNA between adjacent normal tissue and EC tissue,the expression levels of miR-487a-3p and AKIP1 mRNA in the EC tissue among patients with different clinical pathological parameters,and the clinical pathological parameters and the expression levels of miR-487a-3p and AKIP1 mRNA in the EC tissue between the EC survival group and the EC death group.The correlations of miR-487a-3p and AKIP1 mRNA levels in the EC tissue with the degree of tumor differentiation,International Federation of Gynecology and Obstetrics (FIGO) stage,lymph node metastasis,and depth of muscle invasion were analyzed.The relationships of miR-487a-3p and AKIP1 mRNA with patient prognosis and the risk factors affecting the survival of EC patients within 5 years after surgery were analyzed to evaluate the value of miR-487a-3p and AKIP1 mRNA levels in predicting the survival of EC patients within 5 years after survival. Results The EC tissue showed lower miR-487a-3p level (0.41±0.08 vs. 1.00±0.05;t=71.306,P<0.001) and higher AKIP1 mRNA level (2.35±0.37 vs. 1.00±0.03;t=41.465,P<0.001) than the adjacent normal tissue.The miR-487a-3p low expression group and AKIP1 mRNA high expression group had higher proportions of patients with low tumor differentiation,FIGO stage Ⅲ to Ⅳ,lymph node metastasis,and deep invasion of muscle layer than the miR-487a-3p high expression group and AKIP1 mRNA low expression group,respectively (all P<0.05).The results of dual luciferase reporter gene assay showed that the relative activity of luciferase in the miR-487a-3p small interfering RNA (siRNA)+AKIP1 mRNA-wild type (WT) group was higher than that in the miR-487a-3p empty vector+AKIP1 mRNA-WT group (2.85±0.19 vs. 1.00±0.04;t=23.339,P<0.001).There was no significant difference in the relative activity of luciferase between the miR-487a-3p empty vector+AKIP1 mRNA-mutant type (MUT) group and the miR-487a-3p siRNA+AKIP1 mRNA-MUT group (1.04±0.05 vs. 1.05±0.03;t=0.420,P=0.683).MiR-487a-3p in the EC tissue had negative correlations with AKIP1 mRNA,FIGO stage,lymph node metastasis,and depth of muscle invasion and a positive correlation with the degree of tumor differentiation (all P<0.001).AKIP1 mRNA had positive correlations with FIGO stage,lymph node metastasis,and depth of muscle invasion and a negative correlation with the degree of tumor differentiation (all P<0.001).The 5-year overall survival rates in the miR-487a-3p high expression group and AKIP1 mRNA low expression group (89.47% and 84.91%) were higher than those in the miR-487a-3p low expression group and AKIP1 mRNA high expression group (49.09% and 55.93%),respectively (both P<0.05).The EC death group had higher proportions of patients with low tumor differentiation,FIGO stage Ⅲ to Ⅳ,lymph node metastasis,and deep invasion of muscle layer,higher AKIP1 mRNA level in the EC tissue,and lower miR-487a-3p level than the EC survival group (all P<0.05).Low tumor differentiation,FIGO stage Ⅲ to Ⅳ,lymph node metastasis,deep invasion of muscle layer,low miR-487a-3p level,and high AKIP1 mRNA level were independent risk factors for the survival of EC patients within 5 years after surgery (all P<0.05).The area under curve (AUC) values of miR-487a-3p and AKIP1 mRNA alone (0.785 and 0.789,respectively) were lower than that of their combination (0.908) in predicting the survival of EC patients within 5 years after surgery (both P<0.05). Conclusion The EC tissue has a low miR-487a-3p level and a high AKIP1 mRNA level,both of which are correlated with clinicopathological parameters and prognosis and can be used to predict the survival of EC patients within 5 years after surgery.

Objective The purpose of this study was to investigate how miR-200b-3p inhibitors the proliferation and metastasis of endometrial cancer(EC) cells by inducing the expression of FOS-like antigen 2(FOSL2) of activator protein 1(AP1) transcription family. Methods Endometrial cancer cell line HEC-1-A was divided into 12 groups: NC-mimic (transfected with negative control NC mimic), miR-200b-3p mimic (transfected with miR-200b-3p mimic), NC-inhibitor (transfected with negative control NC inhibitor), miR-200b-3p inhibitor group (transfected with miR-200b-3p inhibitor), si-NC (transfected with negative control Si-NC), si-FOSL2 (transfected with si-FOSL2), oe-NC (transfected with negative control oe-NC), oe-FOSL2 group (oe-FOSL2), miR-200b-3p mimic+oe-NC group (co-transfected with miR-200b-3p mimic and oe-NC), miR-200b-3p mimic+oe-FOSL2 group (co-transfected with miR-200b-3p mimic and oe-FOSL2), miR-200b-3p inhibitor+si-NC group (co-transfected with miR-200b-3p inhibitor and si-NC), miR-200b-3p inhibitor+si-FOSL2 group (co-transfected with miR-200b-3p inhibitor and si-FOSL2). Real-time fluorescence quantitative PCR, Western blot, CCK-8 assay, scratch test and Transwell assay were used to detect the expression of miR-200b-3p mRNA, FOSL2 mRNA and protein expression level, cell proliferation, migration and invasion. Results In endometrial cancer cell lines, the expression of miR-200b-3p was significantly down-regulated, while the expression of FOSL2 was significantly up-regulated. Compared with NC-mimic group, the expression of FOSL2, N-cadherin and Vimentin in miR-200b-3p mimic group was significantly decreased, and the expression of E-cadherin was significantly increased. The cell proliferation, migration rate and the number of transmembrane cells were significantly decreased. Compared with the miR-200b-3p mimic+oe-NC group, the expression of FOSL2, N-cadherin and Vimentin in miR-200b-3p mimic+oe-FOSL2 group was significantly increased, and the expression level of E-cadherin was significantly decreased, and the cell proliferation, migration rate and the number of transmembrane cells were significantly increased. Compared with NC-inhibitor group, the expression of FOSL2, N-cadherin and Vimentin in miR-200b-3p inhibitor group was significantly increased, and the expression of E-cadherin was significantly decreased. The cell proliferation, migration rate and the number of transmembrane cells were significantly increased. Compared with the miR-200b-3p inhibitor+si-NC group, the expression of FOSL2, N-cadherin and Vimentin in miR-200b-3p inhibitor+si-FOSL2 group was significantly decreased, and the expression of E-cadherin was significantly increased; the cell proliferation, migration rate and the number of transmembrane cells were significantly decreased. Conclusion The expression of miR-200b-3p in endometrial cancer cells is down-regulated, which can inhibitor the proliferation, migration and invasion of endometrial cancer cells by regulating the EMT process, and its mechanism is related to its targeted negative regulation of FOSL2 expression.

BACKGROUND: Observational research has reported that systemic lupus erythematosus (SLE) is related to common female hormone-dependent cancers, but the underlying causal effect remains undefined. This study aimed to explore the causal association of these conditions by Mendelian randomization (MR) analysis. METHODS: We selected instrumental variables for SLE from genome-wide association studies (GWASs) conducted in European and East Asian populations. The genetic variants for female malignant neoplasms were obtained from corresponding ancestry GWASs. We utilized inverse variance weighted (IVW) as the primary analysis, followed by sensitivity analysis. Furthermore, we conducted multivariable MR (MVMR) to estimate direct effects by adjusting for the body mass index and estradiol. Finally, we implemented reverse direction MR analysis and gave a negative example to test the reliability of MR results. RESULTS: We found SLE was significantly negatively associated with overall endometrial cancer risk (odds ratio [OR] = 0.961, 95% confidence interval [CI] = 0.935-0.987, P  = 3.57E-03) and moderately inversely related to endometrioid endometrial cancer (ENEC) (OR = 0.965, 95% CI = 0.936-0.995, P  = 0.024) risk in the European population by IVW. We replicated these results using other MR models and detected a direct effect by MVMR (overall endometrial cancer, OR = 0.962, 95% CI = 0.941-0.983, P  = 5.11E-04; ENEC, OR = 0.964, 95% CI = 0.940-0.989, P  = 0.005). Moreover, we revealed that SLE was correlated with decreased breast cancer risk (OR = 0.951, 95% CI = 0.918-0.986, P  = 0.006) in the East Asian population by IVW, and the effect was still significant in MVMR (OR = 0.934, 95% CI = 0.859-0.976, P  = 0.002). The statistical powers of positive MR results were all >0.9. CONCLUSION This finding suggests a possible causal effect of SLE on the risk of overall endometrial cancer and breast cancer in European and East Asian populations, respectively, by MR analysis, which compensates for inherent limitations of observational research.

BACKGROUND: Steroid receptor-associated and regulated protein (SRARP) suppresses tumor progression and modulates steroid receptor signaling by interacting with estrogen receptors and androgen receptors in breast cancer. In endometrial cancer (EC), progesterone receptor (PR) signaling is crucial for responsiveness to progestin therapy. The aim of this study was to investigate the role of SRARP in tumor progression and PR signaling in EC. METHODS: Ribonucleic acid sequencing data from the Cancer Genome Atlas, Clinical Proteomic Tumor Analysis Consortium, and Gene Expression Omnibus were used to analyze the clinical significance of SRARP and its correlation with PR expression in EC. The correlation between SRARP and PR expression was validated in EC samples obtained from Peking University People's Hospital. SRARP function was investigated by lentivirus-mediated overexpression in Ishikawa and HEC-50B cells. Cell Counting Kit-8 assays, cell cycle analyses, wound healing assays, and Transwell assays were used to evaluate cell proliferation, migration, and invasion. Western blotting and quantitative real-time polymerase chain reaction were used to evaluate gene expression. The effects of SRARP on the regulation of PR signaling were determined by co-immunoprecipitation, PR response element (PRE) luciferase reporter assay, and PR downstream gene detection. RESULTS: Higher SRARP expression was significantly associated with better overall survival and disease-free survival and less aggressive EC types. SRARP overexpression suppressed growth, migration, and invasion in EC cells, increased E-cadherin expression, and decreased N-cadherin and Wnt family member 7A ( WNT7A ) expression. SRARP expression was positively correlated with PR expression in EC tissues. In SRARP -overexpressing cells, PR isoform B (PRB) was upregulated and SRARP bound to PRB. Significant increases in PRE-based luciferase activity and expression levels of PR target genes were observed in response to medroxyprogesterone acetate. CONCLUSIONS This study illustrates that SRARP exerts a tumor-suppressive effect by inhibiting the epithelial-mesenchymal transition via Wnt signaling in EC. In addition, SRARP positively modulates PR expression and interacts with PR to regulate PR downstream target genes.

Objective: To investigate the effect of long non-coding RNA urothelial carcinoma-associated 1 (UCA1) gene on the proliferation, migration, apoptosis and immune escape of endometrial cancer cells and its molecular mechanism. Methods: Endometrial cancer tissues and adjacent normal tissues of patients with endometrioid adenocarcinoma who underwent total or partial hysterectomy in Henan Provincial People's Hospital from 2017 to 2019 were collected. The expressions of UCA1 and miR-204-5p were detected by real-time fluorescence quantitative polymerase chain reaction (RT-qPCR), and the cell proliferation, migration and apoptosis were detected by cell counting kit 8 (CCK8) method, Transwell method, flow cytometry, and dual-luciferase reporter assay was used to explore the target relationship between UCA1 and miR-204-5p. HEC-1A-sh-NC or HEC-1A-sh-UCA1 cells were co-cultured with peripheral blood mononuclear cells (PBMC) or cytokine-induced killer cells in vitro to explore the role of UCA1 in immune escape. Results: The expression level of UCA1 in endometrial cancer tissue (17.08±0.84) was higher than that in adjacent normal endometrial tissue (3.00±0.37), and the expression level of miR-204-5p (0.98±0.16) was lower than that in adjacent normal endometrial tissue (2.00±0.20, P<0.05). Pearson correlation analysis showed that the expression of miR-204-5p was negatively correlated with the expression of UCA1 (r=-0.330, P=0.030). The expressions of UCA1 and miR-204-5p were associated with the International Federation of Gynecology and Obstetrics stage of endometrial cancer, lymph node metastasis and vascular invasion (P<0.05). The relative ratio of absorbance (0.58±0.11) and the number of cell migration [(199.68±18.44)] in the sh-UCA1 group were lower than those in the sh-NC group (1.24±0.17 and 374.76±24.83), respectively. The apoptosis rate of sh-UCA1 group [(28.64±7.80)%] was higher than that of sh-NC group [(14.27±4.38)%, P<0.05]. After different ratios of effector cells and target cells were cultured, the cell survival rate of HEC-1A-sh-UCA1 group was lower than that of HEC-1A-sh-NC group, and the difference was statistically significant (P<0.05). UCA1 had a binding site for miR-204-5p. The relative ratio of absorbance (1.74±0.08) and the number of cell migration (426.00±18.00) cells in the UCA1+ anti-miR-204-5p group were higher than those in the control group [1.00±0.03 and (284.00±8.00) cells, respectively]. The apoptosis rate of UCA1+ anti-miR-204-5p group [(5.42±0.93)%] was lower than that of control group [(14.82±1.48)%, P<0.05]. HEC-1A-sh-UCA1 cells could induce higher interferon gamma (IFN-γ) expression when co-cultured with PBMC, and the levels of IFN-γ expression in PHA group and PHA+ pre-miR-204-5p group cells were 2.42±0.49 and 1.88±0.26, which were higher than that in the PHA+ pre-NC group (0.85±0.10, P<0.05). When co-cultured with cytokine-induced killer cells (different ratios) in vitro, the HEC-1A-sh-UCA1 group and the HEC-1A-pre-miR-204-5p group had lower survival rates than that in the HEC-1A-pre-miR-204-5p group. In the HEC-1A-pre-NC group, the differences were statistically significant (P<0.05). Conclusion: UCA1/miR-204-5p may play an important role in human endometrial cancer.

OBJECTIVE: To study the role of apolipoprotein E (APOE) in regulating endometrial cancer metastasis and explore the signaling pathway in the regulatory mechanism. METHODS: Human endometrial cancer cell line HEC-1B was transfected with a control siRNA (siCtrl) or a specific siRNA targeting APOE (siAPOE) or with either pEGFP-N1 plasmid or an APOEoverexpressing plasmid. The changes in migration, proliferation, apoptosis and cell cycle of the transfected cells were examined using wound healing assay, Transwell migration assay, MTT assay, flow cytometry, and Hoechst staining. The activity of the ERK/MMP9 signaling pathway in the transfected cells was assessed using RT-qPCR and Western blotting. The expression level of APOE in clinical specimens of endometrial cancer tissues were detected using immunohistochemistry and its correlation with differentiation of endometrial cancer tissues was analyzed. RESULTS: Wound healing assay and Transwell migration assay showed that compared with those in siCtrl group, HEC-1B cells transfected with siAPOE showed significantly reduced migration ability (P < 0.05), whereas APOE overexpression significantly promoted the migration of the cells (P < 0.05). Neither APOE knockdown nor overexpression produced significant effects on HEC-1B cell proliferation as shown by MTT assay and flow cytometry. Hoechst staining revealed that transfection with siAPOE did not significantly affect apoptosis of HEC-1B cells. APOE knockdown obviously reduced and APOE overexpression enhanced ERK phosphorylation and MMP9 expression in HEC-1B cells (P < 0.05). Treatment with U0126 partially reversed the effects of APOE overexpression on ERK phosphorylation, migration and MMP9 expression in HEC-1B cells (P < 0.05). APOE is highly expressed in clinical samples of endometrial cancer tissues as compared with the adjacent tissues. CONCLUSION APOE is highly expressed in endometrial cancer tissues to promote cancer cell migration by enhancing ERK phosphorylation and MMP9 expression.

Objective: To explore the concordance and causes of different mismatch repair (MMR) and microsatellite instability (MSI) detection results in endometrial carcinoma (EC) molecular typing. Methods: A total of 214 EC patients diagnosed from January 2021 to April 2023 were selected at the Department of Pathology, Peking University Third Hospital. The immunohistochemistry (IHC) results of MMR protein were reviewed. Tumor specific somatic mutations, MMR germline mutations, microsatellite scores and tumor mutation burden (TMB) were detected by next-generation sequencing (NGS) with multi-gene panel. Methylation-specific PCR was used to detect the methylation status of MLH1 gene promoter in cases with deficient MLH1 protein expression. In cases with discrepant results between MMR-IHC and MSI-NGS, the MSI status was detected again by PCR (MSI-PCR), and the molecular typing was determined by combining the results of TMB and MLH1 gene promoter methylation. Results: (1) In this study, there were 22 cases of POLE gene mutation subtype, 55 cases of mismatch repair deficient (MMR-d) subtype, 29 cases of p53 abnormal subtype, and 108 cases of no specific molecular profile (NSMP). The median age at diagnosis of MMR-d subtype (54 years old) and the proportion of aggressive histological types (40.0%, 22/55) were higher than those of NSMP subtype [50 years old and 12.0% (13/108) respectively; all P<0.05]. (2) Among 214 patients, MMR-IHC test showed that 153 patients were mismatch repair proficient (MMR-p), 49 patients were MMR-d, and 12 patients were difficult to evaluate directly. MSI-NGS showed that 164 patients were microsatellite stable (MSS; equal to MMR-p), 48 patients were high microsatellite instability (MSI-H; equal to MMR-d), and 2 patients had no MSI-NGS results because the effective sequencing depth did not meet the quality control. The overall concordance between MMR-IHC and MSI-NGS was 94.3% (200/212). All the 12 discrepant cases were MMR-d or subclonal loss of MMR protein by IHC, but MSS by NGS. Among them, 10 cases were loss or subclonal loss of MLH1 and (or) PMS2 protein. Three discrepant cases were classified as POLE gene mutation subtype. In the remaining 9 cases, 5 cases and 3 cases were confirmed as MSI-H and low microsatellite instability (MSI-L) respectively by MSI-PCR, 6 cases were detected as MLH1 gene promoter methylation and 7 cases demonstrated high TMB (>10 mutations/Mb). These 9 cases were classified as MMR-d EC. (3) Lynch syndrome was diagnosed in 27.3% (15/55) of all 55 MMR-d EC cases, and the TMB of EC with MSH2 and (or) MSH6 protein loss or associated with Lynch syndrome [(71.0±26.2) and (71.5±20.1) mutations/Mb respectively] were significantly higher than those of EC with MLH1 and (or) PMS2 loss or sporadic MMR-d EC [(38.2±19.1) and (41.9±24.3) mutations/Mb respectively, all P<0.01]. The top 10 most frequently mutated genes in MMR-d EC were PTEN (85.5%, 47/55), ARID1A (80.0%, 44/55), PIK3CA (69.1%, 38/55), KMT2B (60.0%, 33/55), CTCF (45.5%, 25/55), RNF43 (40.0%, 22/55), KRAS (36.4%, 20/55), CREBBP (34.5%, 19/55), LRP1B (32.7%, 18/55) and BRCA2 (32.7%, 18/55). Concurrent PTEN, ARID1A and PIK3CA gene mutations were found in 50.9% (28/55) of MMR-d EC patients. Conclusions: The concordance of MMR-IHC and MSI-NGS in EC is relatively high.The discordance in a few MMR-d EC are mostly found in cases with MLH1 and (or) PMS2 protein loss or MMR protein subclonal staining caused by MLH1 gene promoter hypermethylation. In order to provide accurate molecular typing for EC patients, MLH1 gene methylation, MSI-PCR, MMR gene germline mutation and TMB should be combined to comprehensively evaluate MMR and MSI status.

YWHAE gene is located on chromosome 17p13.3, and its product 14-3-3epsilon protein belongs to 14-3-3 protein family. As a molecular scaffold, YWHAE participates in biological processes such as cell adhesion, cell cycle regulation, signal transduction and malignant transformation, and is closely related to many diseases. Overexpression of YWHAE in breast cancer can increase the ability of proliferation, migration and invasion of breast cancer cells. In gastric cancer, YWHAE acts as a negative regulator of MYC and CDC25B, which reduces their expression and inhibits the proliferation, migration, and invasion of gastric cancer cells, and enhances YWHAE-mediated transactivation of NF-κB through CagA. In colorectal cancer, YWHAE lncRNA, as a sponge molecule of miR-323a-3p and miR-532-5p, can compete for endogenous RNA through direct interaction with miR-323a-3p and miR-532-5p, thus up-regulating K-RAS/ERK/1/2 and PI3K-AKT signaling pathways and promoting the cell cycle progression of the colorectal cancer. YWHAE not only mediates tumorigenesis as a competitive endogenous RNA, but also affects gene expression through chromosome variation. For example, the FAM22B-YWHAE fusion gene caused by t(10; 17) (q22; p13) may be associated with the development of endometrial stromal sarcoma. At the same time, the fusion transcript of YWHAE and NUTM2B/E may also lead to the occurrence of endometrial stromal sarcoma. To understand the relationship between YWHAE, NUTM2A, and NUTM2B gene rearrangement/fusion and malignant tumor, YWHAE-FAM22 fusion gene/translocation and tumor, YWHAE gene polymorphism and mental illness, as well as the relationship between 17p13.3 region change and disease occurrence. It provides new idea and basis for understanding the effect of YWHAE gene molecular mechanism and genetic variation on the disease progression, and for the targeted for the diseases.
