Objective: To explore the interfering effects of siRNA on endogenous VEGF-C genes and the protein expression in gastric cancer cells.
Methods: Cultured gastric cancer cell line SGC7901 cells were prepared in vitro. Five siRNA primers of VEGF-C were designed depending on the sequence of Accession No. BC035212. 1 in Genbank. After homology analysis, the primers were synthesized and transfected into SGC7901 cells. The endogenous VEGF-C mRNA level and its protein expression were observed.
Results: VEGF-C-siRNA was inserted into the gastric cancer cell successfully. Five siRNA primers of VEGF-C could inhibit VEGF-C genes and protein expression.
Conclusion: siRNA could block the endogenous VEGF-C genes and the protein expression in gastric cancer cell.

Long noncoding RNAs (lncRNAs) are key regulators during gastric cancer (GC) development and may be viable treatment targets. In the present study, we showed that the expression of the long intergenic noncoding RNA 01016 (LINC01016) is significantly higher in GC tissues with lymph node metastasis (LNM) than those without LNM. LINC01016 overexpression predicts a poorer relapse-free survival (RFS) and overall survival (OS).

Gastric cancer (GC) is a significant global health challenge, particularly in high-incidence regions like East Asia. Despite improvements in screening and treatment, the progressive nature of precancerous lesions-such as atrophic gastritis, intestinal metaplasia, and dysplasia-necessitates effective prevention strategies. This review evaluates the role of chemoprevention in GC, focusing on agents designed to target these precancerous lesions.

SLC26A9 is a member of the Slc26a family of multifunctional anion transporters that function as Cl channels in the stomach. We reported for the first time that SLC26A9 is involved in gastric tumorigenesis. However, the role of SLC26A9 in breast cancer has not yet been investigated.

T-cell lymphomas (TCLs) are heterogeneous malignancies with limited treatment options and poor outcomes. The efficacy of traditional T-cell therapies, including chimeric antigen receptor (CAR) T cells, is often constrained by immunosuppressive factors and the tumor microenvironment. On the other hand, although direct Granzyme B (GrB) administration can effectively induce tumor cell apoptosis, it lacks universal tumor targeting and efficient cellular entry mechanisms.

Objective: To investigate the role of long non-coding RNAs (lncRNAs) in the metabolic reprogramming of gastric cancer through their regulation of mesenchymal stem cells (MSCs) and HERPUD1 protein targets, aiming to elucidate mechanisms that could lead to novel therapeutic strategies.
Method: The RNA-seq was performed on BGC and hMSC-BGC cells to perform LncRNA screening. And we employed cell culture techniques using hMSC-BM and BGC823 cells, treated with various genetic interventions including siRNA and overexpression vectors.
