To investigate whether myeloid Ddr2 regulates melanoma growth and metastasis, we injected B16BL6 melanoma cells into Ddr2^LysM (cKO) mice via subcutaneous neck, tail vein, and left ventricle, respectively. We found that the growth of melanoma cells in cKO mice was significantly retarded, as demonstrated by the subcutaneous transplantation tumor model. Unexpectedly, the melanoma metastasis to the lung or bone was significantly stimulated in cKO mice, indicating the complicated role of Ddr2 in macrophages in melanoma development. Furthermore, Ddr2 in macrophages regulated the migration of B16BL6 cells in the co-culture system. Bioinformatics analysis showed that Ddr2 expression correlates with improved prognostic outcomes in melanoma, and high expression of Ddr2 is protective in melanoma metastasis.

Unresectable HCC patients with an Eastern Cooperative Oncology Group (ECOG) physical status score ≤ 1 and a Child-Pugh score ≤ 7 who had not received systemic therapy were included in this single-arm, exploratory, multicentre phase II clinical study.

The patients were treated with envafolimab (150 mg, QW, subcutaneous) in combination with lenvatinib (12 mg for patients weighing over 60 kg, 8 mg for patients weighing under 60 kg). The co-primary endpoint of the study was overall survival (OS), while surrogate endpoints included progression-free survival (PFS), objective response rate (ORR), disease control rate (DCR), and safety.

Recent advancements in next-generation sequencing (NGS) have enabled the identification of novel chromosomal translocations and fusion genes, which play a critical role in sarcoma subtypes. Our study focuses on gene fusions in sarcomas among Chinese patients, comparing their genomic profiles to those of Western populations. We analyzed 1048 sarcoma samples from Chinese patients using a panel of over 500 genes, identifying 481 gene fusions in 329 patients. The most common fusions included EWSR1, HMGA2, and SS18, with notable subtype-specific fusions such as EWSR1-FLI1 in Ewing sarcoma and NAB2-STAT6 in solitary fibrous tumors. In comparison to Chinese and Western populations, variations in fusion spectrum exist, potentially necessitating distinct treatment strategies; however, further validation of these fusions is warranted. Our findings highlight the importance of gene fusions as diagnostic markers and potential therapeutic targets. Actionable fusions, including kinase-related fusions like ALK, NTRK3, and BRAF, were detected in 67 patients (6.4%) and may guide precision therapies. Additionally, we observed the frequent co-occurrence of genomic alterations, particularly in cell cycle regulators such as CDK4 and MDM2.

We detected the changes of immune cell populations after anti-PD-L1 treatment in melanoma xenograft mouse model.

Next, we tested the therapeutic effect and regulatory effect on the tumor microenvironment with anti-PD-L1 and MnCl₂ via combining treatment with anti-PD-L1 and MnCl₂. Anti-PD-L1 therapy has a certain tumor suppressive function, but the effect is not ideal. The results of flow cytometry showed that the number of CD4⁺ T cells and CD8⁺ T cells significantly increased after anti-PD-L1 treatment.
