Aim: To construct the melanoma antigen-1(MAGE-1) eukaryotic expression plasmid and express MAGE-1 in mouse melanoma B16 cells.

Methods: The MAGE-1 gene was amplified by PCR and cloned into the eukaryotic expression vector pIRES2-EGFP to construct the pIRES2-EGFP-MAGE-1 plasmid. The plasmid was transfected into the B16 cells. The EGFP expression was detected under fluoroscent microscope and the MAGE-1 expression was detected by immunohistochemistry staining.

Results: The eukaryotic expression vector pIRES2-EGFP-MAGE-1 was constructed and transfected successfully into B16 cells, and the EGFP and MAGE-1 genes were co-expressed in the B16 cells.

Conclusion: A mouse melanoma cell line B16 co-expressing MAGE-1 and EGFP genes has been established successfully, which lays the foundation for the research on application of MAGE-1 in the tumor immunotherapy.

Inhibitors of the PD-1/PD-L1 immune checkpoint have revolutionized cancer treatment. However, the clinical response remains limited, with only 20% of patients benefiting from treatment and approximately 60% of PD-L1-positive patients exhibiting resistance. One key factor contributing to resistance is the externalization of phosphatidylserine (PS) on the surface of cancer cells, which suppresses immune responses and promotes PD-L1 expression, further hindering the efficacy of PD-L1 blockade therapies.

Melanoma is among the most common malignancies and has recently exhibited increased resistance to treatments, resulting in a more aggressive disease course. Mesenchymal stem cells (MSCs) secrete cytokines both in vivo and in vitro, which regulate tumor cell signaling pathways and the tumor microenvironment, thereby influencing tumor progression. This study investigates the anti-melanogenesis effects of sheep umbilical cord mesenchymal stem cells (SUCMSCs) to assess their potential application in melanoma treatment.

In this work, a series of boronated amidines based on the -dodecaborate anion and amino acids containing an amino group in the side chain of the general formula [BHNHC(NH(CH)CH(NH)COOH)CH], where n = 2, 3, 4, were synthesized. These derivatives contain conserved α-amino and α-carboxyl groups recognized by the binding centers of the large neutral amino acid transporter (LAT) system, which serves as a target for the clinically applied BNCT agent para-boronophenylalanine (BPA). The paper describes several approaches to synthesizing the target compounds, their acute toxicity studies, and tumor uptake studies in vivo in two tumor models.

Melanoma is among the most abundant malignancies in the US and worldwide. Ligstroside aglycone (LA) is a rare extra-virgin olive oil-derived monophenolic secoiridoid with diverse bioactivities. LA dose-response screening at the NCI 60 cancer cells panel identified the high sensitivity of the Malme-3M cell line, which harbors a mutation.

Background: The use of immune checkpoint inhibitors (CPIs) has become a dominant regimen in modern cancer therapy, however immune resistance induced by tumor-associated macrophages (TAMs) with immune suppressive and evasion properties limits responses. Therefore, the rational design of immune modulators that can control the immune suppressive properties of TAMs and polarize them, as well as dendritic cells (DCs), toward a more proinflammatory phenotype is a principal objective in cancer immunotherapy.

Methods: Here, using a protein engineering approach to enhance cytokine residence in the tumor microenvironment, we examined combined stimulation of the myeloid compartment via tumor stroma-binding granulocyte-macrophage colony-stimulating factor (GM-CSF) to enhance responses in both DCs and T cells via stroma-binding interleukin-12 (IL-12).
