IL-32 and its paradoxical role in neoplasia.

Interleukin-32 (IL-32) is an interleukin cytokine usually linked to inflammation. In recent years, it has been found that IL-32 exhibits both pro- and anti-tumor effects. Although most of those effects from IL-32 appear to favor tumor growth, some isoforms have shown to favor tumor suppression. This suggests that the role of IL-32 in neoplasia is very complex. Thus, the role of IL-32 in these various cancers and protein pathways makes it a very crucial component to consider when looking at potential therapeutic options in tumor treatment. In this review, we will explore what is currently known about IL-32, including its relationship with tumorigenesis and the potential for IL-32 to enhance local and systemic anti-tumor immune responses. Such a study might be helpful to accelerate the development of IL-32-based immunotherapies.

The past, present, and future of immunotherapy for colorectal cancer.

Colorectal cancer is prevalent worldwide, with various factors influencing the survival rate of late-stage metastatic cases. Current standard treatments include surgical removal, adjuvant chemotherapy, and neoadjuvant chemotherapy. Novel immunotherapy research shows promising results for various cancer types, including colorectal cancer. Current immunotherapy options are limited to specific molecular subtypes of colorectal cancer, while the remaining are limited to standard protocol. This review article summarizes approved, developing, and potential sources for novel colorectal cancer immunotherapy treatment through active-specific, checkpoint inhibitor, cytokine, cytotoxic, and adoptive T-cell immunotherapy. Such a study would be beneficial to patients with colorectal cancer.

CTHRC1 Is Associated With Immune Escape and Poor Prognosis in Gastric Cancer.

BACKGROUND/AIM: Collagen triple helix repeat containing-1 (CTHRC1) promotes tumor progression by regulating the immunosuppression of the tumor microenvironment. However, the function of CTHRC1 in gastric cancer (GC) and its relationship with tumor-infiltrating immune cells remains unclear. PATIENTS AND METHODS: Data were downloaded from The Cancer Genome Atlas (TCGA) database. The difference in expression of CTHRC1 in GC and adjacent non-tumor tissues was analyzed by R software and verified by the online database Oncomine. A Kaplan-Meier survival analysis was selected for evaluating the impact of CTHRC1 expression on the survival of GC and verified by the Kaplan-Meier plotter. The relationship between CTHRC1 expression and clinicopathological parameters was assessed by univariate and multivariate Cox regression. The correlation with tumor-infiltrating immune cells was analyzed by Tumor Immune Estimation Resource (TIMER). A gene set enrichment analysis (GSEA) was used to screen the signaling pathways between low and high CTHRC1 expression datasets. RESULTS: The expression of CTHRC1 in GC tissue was higher than that in adjacent non-tumor tissues. The Kaplan-Meier curve showed that patients with higher CTHRC1 expression had a worse prognosis. The univariate and multivariate Cox analyses showed that high expression of CTHRC1 was an important independent predictor of poor overall survival in GC. The TIMER database analysis revealed that CTHRC1 was associated with five tumor immunosuppressive cells in GC. The GSEA indicated that 10 signaling pathways were enriched in samples with a high CTHRC1 expression phenotype. CONCLUSION: CTHRC1 might be a new prognostic biomarker for CG and might be a potential target for treatment of GC.
