| Abstract | Background As one of gynecologic tumors, endometrial carcinoma (EC) has been characterized by high incidence rate, but its molecular pathogenesis has remained unclear. TMED3 is a membrane protein and has been indicated to implicate several tumor-related diseases. In the current study, we aimed to explore the physiological function of TMED3 in EC progression. Methods Through bioinformatic analysis using The Cancer Genome Atlas database and immunohistochemistry assay on tissue microarray, we examined whether TMED3 was upregulated in EC tissues. After constructing TMED3-knockdown cell models via lentiviral transfection, qPCR and western blot were employed to determine the expression levels of TMED3 mRNA and protein. Then, Celigo cell counting assay, CCK8 assay, flow cytometry, wound-healing assay and Transwell assay were used to detect cell proliferation, cell cycle, cell apoptosis and cell migration, respectively. Results As a result, it was found that TMED3 was upregulated in EC cells, which was also verified in clinical samples. We then found that downregulation of TMED3 considerably restrained cell cycle, cell growth and migration but promoted apoptosis of EC cells. The following in-vivo experiments also verified that tumor growth was inhibited after TMED3 knockdown. The exploration in molecular mechanisms showed that TMED3 deletion may weaken cellular viability through upregulating pro-apoptotic proteins and targeting PI3K/AKT signaling pathways. Conclusions This study suggested that knocking down TMED3 affected the malignant phenotype of EC cells and thus limited tumor progression, which provided insights to the development of targeted drugs for EC treatment. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
