A case report of SMARCA4-deficient gastric cancer and review of the literature.

We report the case of a 50-year-old female with gastric carcinoma. The tumor was positive for epithelial and other immunological markers; however, SMARCA4 was completely inactivated. The histological and immunophenotypic findings were consistent with a diagnosis of SMARCA4-DTS.

DcR3-associated risk score: correlating better prognosis and enhanced predictive power in colorectal cancer.

Decoy receptor 3 (DcR3), a novel soluble protein belonging to the tumor necrosis factor receptor (TNFR) family, has been previously associated with tumorigenesis in various cancers. However, in our study, we unexpectedly found that DcR3 may promote patient survival time in colorectal cancer (CRC). Through an analysis of The Cancer Genome Atlas (TCGA) and Gene Expression Omnibus (GEO) datasets, we discovered that high levels of DcR3 are associated with improved overall survival (OS) and disease-free survival (DFS) in CRC patients.

The Influence of NDRG1 Single Nucleotide Polymorphisms on Glioma Risk and Prognosis in Chinese Han Population.

Glioma is a highly fatal malignant tumor with a high recurrence rate, poor clinical treatment effect, and prognosis. We aimed to determine the association between single nucleotide polymorphisms (SNPs) of NDRG1 and glioma risk and prognosis in the Chinese Han population. 5 candidate SNPs were genotyped by Agena MassARRAY in 558 cases and 503 controls; logistic regression was used to analyze the relationship between SNPs and glioma risk.

Ninjurin 2 rs118050317 gene polymorphism and endometrial cancer risk.

Background: Endometrial cancer is one of the most common female reproductive system tumors. Ninjurin2 (NINJ2) is a new adhesion factor. As a vascular susceptibility gene, it is highly expressed in other cancers and promotes the growth of cancer cells.

Ku80 gene knockdown by the CRISPR/Cas9 technique affects the biological functions of human thyroid carcinoma cells.

In the present study, to evaluate the role of Ku80 in thyroid carcinoma (TC), 86 thyroid tissue samples from patients with a spectrum of thyroid disorders were examined for protein levels of Ku80, nuclear factor‑κB (NF‑κB) and RET/TC by immunohistochemistry. Furthermore, in TC cells, Ku80 mRNA was detected by reverse transcription‑quantitative PCR analysis and silenced using the clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR‑associated protein 9 (Cas9) technique to assess its role. An antibody array was used to identify Ku80‑related regulatory genes.

Downregulation of survivin inhibits proliferation and migration of human gastric carcinoma cells.

Gastric cancer is the second leading cause of cancer-related death worldwide. Survivin overexpressed in many human cancers as a member of the inhibitor of apoptosis protein family. We found that all samples of normal gastric tissues did not express the protein of survivin, and however, 65% human gastric cancer samples expressed survivin.
