Cuprotosis is a new programmed cell death related to cancer. However, the characteristics of cuprotosis in gastric cancer (GC) remain unknown. Ten cuprotosis molecules from 1544 GC patients were used to identify three GC molecular genotypes. Cluster A was characterized by the best clinical outcome and was significantly enriched in metabolic signaling pathways. Cluster B exhibited elevated immune activation, high immune stroma scores and was significantly enriched in tumor immune signaling pathways. Cluster C was characterized by severe immunosuppression and poor response to immunotherapy. Notably, the citrate cycle, cell cycle, and p53 signaling pathways were enriched in the differentially expressed genes among the three subtypes, which were critical signaling pathways for cell death. We also developed a cuprotosis signature risk score that could accurately predict the survival, immunity, and subtype of GC. This study presents a systematic analysis of cuprotosis molecules and provides new immunotherapeutic targets for GC patients.

Background: C-C motif chemokine ligand 3 (CCL3) is a crucial chemokine that plays a fundamental role in the immune microenvironment and is closely linked to the development of various cancers. Despite its importance, there is limited research regarding the expression and function of CCL3 in nasopharyngeal carcinoma (NPC). Therefore, this study seeks to examine the expression of CCL3 and assess its clinical significance in NPC using bioinformatics analysis and experiments.

Functioning upstream in immune activation cascades, MIF influences macrophage polarization, T and B cell differentiation, and cytokine expression through CD74, CXCR2/4/7, and downstream signaling via NF-κB, ERK1/2, and PI3K/AKT pathways. This review provides a comprehensive analysis of MIF's mechanistic functions under both physiological and pathological conditions, highlighting its dual role as a protective mediator during acute stress and as a pro-inflammatory amplifier in chronic disease.

Background/aims: Ubiquitin D (UBD), a member of the ubiquitin-like modifier (UBL) family, is significantly overexpressed in various cancers and is positively correlated with tumor progression. However, the role and underlying mechanisms of UBD in rheumatoid arthritis (RA) remain poorly understood. This study aimed to investigate the effects of UBD knockdown on the progression of RA.

Bortezomib resistance in multiple myeloma (MM) is a significant clinical challenge that limits the long-term effectiveness. Currently, there is a lack of reliable biomarkers to predict bortezomib resistance. Previous studies reported that several proteins regulate bortezomib resistance through targeting ubiquitin-proteasome pathways, including heat shock protein family A member 9 (HSPA9), dickkopf Wnt signaling pathway inhibitor 1 (DKK1), proteasome 26S subunit non-ATPase 14 (PSMD14), and tripartite motif containing 21 (TRIM21).

Polyphenols, rich in phenolic structures, are widely found in plants and known for disturbing the cellular oxidative stress and regulating the signal pathways of tumor proliferation and metastasis, making them valuable in cancer therapy. Polyphenols display high adherence due to the presence of phenolic hydroxyl groups, which enables the formation of covalent and non-covalent interactions with different materials. However, nonspecific adhesion of polyphenols carries significant risks in applications as polyphenols might adhere to proteins and polysaccharides in the bloodstream or gastrointestinal tract, leading to thrombosis and lithiasis.
