Corded and hyalinized endometrioid carcinoma (CHEC) is a morphologic variant of endo-metrioid adenocarcinoma. The tumor exhibits a biphasic appearance with areas of traditional low-grade adenocarcinoma merging directly with areas of diffuse growth composed of epithelioid or spindled tumor cells forming cords, small clusters, or dispersed single cells. It is crucial to distinguish CHEC from its morphological mimics, such as malignant mixed mullerian tumor (MMMT), because CHECs are usually low stage, and are associated with a good post-hysterectomy prognosis in most cases while the latter portends a poor prognosis. The patient reported in this article was a 54-year-old woman who presented with postmenopausal vaginal bleeding for 2 months. The ultrasound image showed a thickened uneven echo endometrium of approximately 12.2 mm and a detectable blood flow signal. Magnetic resonance imaging revealed an abnormal endometrial signal, considered endometrial carcinoma (Stage Ⅰ B). On hysterectomy specimen, there was an exophytic mass in the uterine cavity with myometrium infiltrating. Microscopically, most component of the tumor was well to moderately differentiated endometrioid carcinoma. Some oval and spindle stromal cells proliferated on the superficial surface of the tumor with a bundle or sheet like growth pattern. In the endometrial curettage specimen, the proliferation of these stromal cells was more obvious, and some of the surrounding stroma was hyalinized and chondromyxoid, which made the stromal cells form a cord-like arrangement. Immunostains were done and both the endometrioid carcinoma and the proliferating stroma cells showed loss of expression of DNA mismatch repair protein MLH1/PMS2 and wild-type p53 protein. Molecular testing demonstrated that this patient had a microsatellite unstable (MSI) endometrial carcinoma. The patient was followed up for 6 months, and there was no recurrence. We diagnosed this case as CHEC, a variant of endometrioid carcinoma, although this case did not show specific β-catenin nuclear expression that was reported in previous researches. The striking low-grade biphasic appearance without TP53 mutation confirmed by immunohistochemistry and molecular testing supported the diagnosis of CHEC. This special morphology, which is usually distributed in the superficial part of the tumor, may result in differences between curettage and surgical specimens. Recent studies have documented an aggressive clinical course in a significant proportion of cases. More cases are needed to establish the clinical behaviors, pathologic features, and molecular profiles of CHECs. Recognition of the relevant characteristics is the prerequisite for pathologists to make correct diagnoses and acquire comprehensive interpretation.

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 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.

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 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 investigate the molecular classification and clinicopathological features of endometrial carcinoma(EC). Methods: One hundred cases of EC diagnosed in the Department of Pathology, Tianjin Central Hospital of Gynecology and Obstetrics from November 2020 to November 2021 were selected. Sanger sequencing and immunohistochemical staining were used for molecular classification according to the 5th WHO classification. The clinicopathological characteristics of each molecular subtype was analyzed. Results: The 100 EC patients had a mean age of 53 years (range 26 to 72 years). There were 10 cases of POLE mutation (POLE mut), including two cases (2/10) of "binary-classifier" EC, two cases (2/10) of FIGO Grade 3 endometrioid endometrial carcinoma (G3-EEC), and three cases (3/10) of other high-grade subtypes. There were 38 cases of mismatch repair deficiency (dMMR), including one case (1/38, 2.6%) of "binary-classifier" EC and 36 cases (36/38, 94.7%) were EEC. Twenty-one cases (21/38, 55.3%) showed simultaneous loss of expression of MLH1 and PMS2, and 20 cases (20/21, 95.2%) were positive for MLH1 methylation, indicating that they were sporadic EC. Six patients (6/38, 15.8%) were tested for germline detection of Lynch syndrome (LS) related genes, and one patient was LS-related EC. There were 44 cases of non-specific molecular profile (NSMP), including 34 cases (34/44, 77.3%) of G1-2 EEC and seven cases (7/44, 15.9%) of G3-EEC. There were eight cases of p53 abnormality (p53 abn), including four cases (4/8) of G3-EEC, two cases (2/8) of other high-grade subtypes, and one patient had hereditary breast cancer and ovarian cancer syndrome. Conclusions: Correct interpretation of POLE mutation, MMR and p53 immunohistochemistry is the key of molecular classification. The interpretation must strictly follow standard diagnostic procedures and specifications to ensure the accuracy of molecular classification.

Objective: To inhibit the stemness maintenance potential of endometrial cancer and increase the sensitivity of endometrial cancer side population cells to chemotherapy drugs by inducing extensive deSUMOylation modification of proteins. Methods: Flow cytometry was used to sort and culture CD133(+) CD44(+) KLE endometrial cancer cell clone spheres. Protein expression level of small ubiquitin-related modifier 1 (SUMO1) and two stemness maintenance genes of tumor side population cells, octamer binding transcription factor-4 (Oct4) and sex determining region Y-box2 (Sox2), were detected by western blotting method. Lentivirus-mediated Sentrin/SUMO-specific proteases 1 (SENP1) gene was stably transfected into KLE side population cells. Western blotting was used to detect the protein expressions of SENP1, SUMO1, Oct4 and Sox2. The clone formation rate was compared between KLE side population cells with or without SENP1 overexpression. Flow cytometry was applied to detect cell cycle changes. 3-(4, 5-Dimethylthiazole-2)-2, 5-diphenyl-tetrazolium bromide (MTT) experiment and flow cytometry apoptosis method were used to detect the chemosensitivity of the side population of endometrial cancer cells to cisplatin. Tumor-bearing mouse models of endometrial cancer were established to detect the effect of SENP1 overexpression on the chemotherapy sensitivity of cisplatin. Results: Compared with CD133(-)CD44(-) KLE cells, CD133(+) CD44(+) KLE side population cells could form clonal spheres and express higher levels of SUMO1, Oct4 and Sox2 proteins (P<0.05). Compared with KLE side population cells that were not transfected with SENP1 gene, the expression level of SENP1 protein in KLE side population cells overexpressing SUMO1、Oct4 and Sox2 were lower. The clonal sphere formation rate was reduced from (25.67±5.44)% to (7.46±1.42)%, and cell cycle shifted from G(0)/G(1) phase to G(2) phase. IC(50) of cisplatin decreased from (55.46±6.14) μg/ml to (11.55±3.12) μg/ml, and cell apoptosis rate increased from (9.76±2.09)% to (16.79±3.44)%. Overexpression of SENP1 could reduce the tumorigenesis rate of KLE side population cells in vivo and increase their chemotherapy sensitivity to cisplatin (P<0.05). Conclusion: Overexpression of SENP1 can induce protein deSUMOylation modification, inhibit the stemness maintenance potential of endometrial cancer side population cells, and enhance their chemotherapy sensitivity, which provides a new reference for gene therapy of endometrial cancer.

Objective: To explore the expression of miR1290 in endometrial cancer tissues and its relationship with the pathological grade, and to find out the effect of miR1290 on biological characteristics of endometrial cancer cells and its mechanism. Methods: A total of 38 cases of endometrioid adenocarcinoma tissues, 10 cases of adjacent tissues and 23 cases of normal endometrial tissues were collected in Provincial Hospital Affiliated to Shandong University from May 2020 to October 2020. The expression of miR1290 was detected by reverse transcription polymerase chain reaction (RT-PCR). The expressions of miR1290 in endometrial cancer cells including KLE and Ishikawa were knocked down by lentiviral transfection. Cell counting kit 8 (CCK-8) test and colony formation test were used to detect cell proliferation ability, wound healing and Transwell test were used to detect cell invasion and migration ability, western blot was used to detect the expressions of epithelial-mesenchymal transition (EMT), phospholipids acylinositide 3-kinase (PI3K)/Akt and Wnt/β-catenin pathway related proteins. Results: The relative expressions of miR1290 in endometrial cancer tissues were 5.40±3.20, which was 1.55 times of normal endometrial tissues (P<0.01) and 1.75 times of adjacent tissues (P<0.01). The relative expressions of miR1290 in 17 cases of endometrial tissues at proliferative stage and 6 cases of endometrial tissues at secretory stage were 3.00±1.08 and 4.97±0.58, respectively, and the difference was statistically significant (P<0.01). In KLE cells and Ishikawa cells, the expression of miR1290 in miR1290 knockdown (Sh-miR1290) group was decreased when compared with the negative control (Sh-NC) group. The absorbance value of Sh-miR1290 group detected by the CCK-8 method and the colony formation rate detected by the colony formation experiment were both increased, the number of cells penetrating the basement membrane in the Transwell experiment and the wound healing rate in the scratch experiment were decreased (P<0.05). In KLE cells, knockdown of miR1290 reduced the expressions of EMT-related proteins including N-cadherin, Vimentin, Snail and Slug(P<0.05), and the expressions of PI3K and P-Akt/Akt (P<0.05), while there was no significant change in the expressions of Wnt and β-catenin (P>0.05). In Ishikawa cells, knockdown of miR1290 decreased the expressions of EMT-related proteins including N-cadherin, Snail and Slug, and the expressions of Wnt and β-catenin, increased the expression of E-cadherin (P<0.05), while there was no significant change in the expressions of PI3K and P-Akt/Akt (P>0.05). Conclusions: The expressions of miR1290 in endometrial cancer tissues are higher than that in the adjacent tissues and normal endometrial tissues. Knockdown of miR1290 expression can promote the proliferation of endometrial cancer cells, but inhibit cell invasion, migration and EMT ability through the PI3K/Akt and Wnt/β-catenin pathways.

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.
