Copper is an essential micronutrient in the human body, mainly acting as a crucial cofactor required for a wide range of physiological processes across nearly all cell types. Recent advances revealed that tumor cells seize copper to fulfill their rapid proliferation, metastasis, immune evasion, and so on by reprogramming the copper regulatory network, defined as cuproplasia. Thus, targeting copper chelation to reduce copper levels has been considered a rational tumor therapy strategy.

The advent of immunotherapy in cancer has provided new avenues in the treatment of many malignancies at various stages. Specifically, immune checkpoint inhibitors (ICIs) have transformed the field of lung cancer treatment. However, since some tumors can evade the immune system, not all patients respond properly.

Background: Diffuse large B-cell lymphoma (DLBCL) is a prevalent and aggressive form of non-Hodgkin's lymphoma with a complex etiology. NOP2/Sun domain 2 (NSUN2) is an RNA methyltransferase that has been linked to the regulation of gene expression in various cancers. However, the function of NSUN2 in DLBCL, specifically its contribution to exosome-driven tumor progression, remains to be thoroughly elucidated.

Protein lactylation, an emerging post-translational modification, is providing new insights into tumor biology and challenging our current understanding of cancer mechanisms. Our review illuminates the intricate roles of lactylation in carcinogenesis, tumor progression, and therapeutic responses, positioning it as a critical linchpin connecting metabolic reprogramming, epigenetic modulation, and treatment outcomes. We provide an in-depth analysis of lactylation's molecular mechanisms and its far-reaching impact on cell cycle regulation, immune evasion strategies, and therapeutic resistance within the complex tumor microenvironment.

The programmed cell death 1 (PD-1)/PD-1 ligand 1 (PD-L1) axis mediates immune evasion of tumor, and targeting this axis has achieved some clinical benefits. The regulation of PD-1 expression in immune cells has been well studied. However, whether any other potential source of immune cell-expressed PD-1 exists remains unknown.
