Objective: To explore expression changes and clinical significance of EBI3 in gastric cancer.
Methods: Expression of EBI3 in gastric cancer (GC) cell lines, GC tissues, and corresponding adjacent tissues were detected by qRT-PCR, Western blot, or immunohistochemistry. The relationship between the EBI3 expression and clinicopathological features of GC patients was analyzed. Expression of EBI3 in BGC-823 was overexpressed or downregulated, then, the changes of proliferation, migration, invasion, and tumorigenicity of BGC-823 were observed by MTT, scratch test, Transwell test, and tumorigenesis assay model.
Results: EBI3 was lowly expressed in GC tissues. EBI3 expression in BGC823 was highest than other cell lines. EBI3 expression was significantly associated with TNM stage. GC patients with low expression of EBI3 had a rather poor prognosis than the GC patients with high expression of EBI3. Low EBI3 expression was an independent risk predictor of the prognosis of GC patients. After EBI3 was overexpressed, the viability, migration, invasion, and tumorigenicity abilities of BGC-823 were significantly reduced. Opposite effect was observed after EBI3 expression was downregulated.
Conclusion: EBI3 low expression is closely related to the malignant degree of GC and may be a predictive indicator of the prognosis of GC and potential therapeutic targets.

Background: Epstein-Barr virus induced gene 3 (), a member of the IL-12 family, is known to be involved in malignant progression in a variety of cancers, but its role in melanoma is unclear. The aim of this study was to explore the effects of EBI3 on the malignant phenotype melanoma to reveal its potential as a therapeutic target.
Methods: In this study, we used bioinformatics to analyze the expression of in pan-cancer and verified its expression level in melanoma cells by reverse transcription-quantitative polymerase chain reaction (RT-qPCR).

Background: Immunotherapy has achieved effective antitumor activity in advanced GC patients. However, the rate of response to ICI therapy is disappointing, T cell exhaustion may contribute to this phenomenon. EBI3 is an emerging immunosuppressive factor, and the association between EBI3 and T cell exhaustion is not clear.

Interleukin-35 (IL-35) is a novel protein comprising IL-12α and IL-27β chains. The IL12A and genes are responsible for its production. The study of IL-35 has experienced a substantial increase in interest in recent years, as demonstrated by many research papers.

Problem: Pregnancy complications such as spontaneous abortion, preeclampsia, and preterm birth persist, despite current interventions aimed at their prevention and treatment largely proving unsuccessful. Interleukin-27 (IL-27), composed of p28 and EBI3 subunits, binds to IL-27R, which consists of gp130 and IL-27Rα (also known as WSX-1 or TCCR), and plays a pivotal role in tumor development and inflammation regulation. At the maternal-fetal interface, IL-27 expression has been detected in trophoblasts, endometrial stromal cells, and decidual cells.

Interleukin 27 (IL-27) is a cytokine that regulates susceptibility to Leishmania infantum infection in humans and experimental models. This cytokine has not yet been described in canine leishmaniasis (CanL). Therefore, we investigated whether IL-27 has a regulatory role in CanL.
