Our previous studies showed that increased Forkhead box protein M1 (FoxM1) expression promotes osteosarcoma progression. While NIMA-related kinase 2 (NEK2) has emerged as a potential oncogenic factor, its functional role and molecular mechanisms in osteosarcoma remain poorly understood. Pearson's correlation analysis was performed to assess the relationship between FoxM1 and NEK2 expression using the GSE33382 dataset from GEO. Coimmunoprecipitation (Co-IP) was employed to investigate FoxM1-NEK2 interactions. NEK2 expression was modulated in the HOS and U2OS osteosarcoma cell lines through pharmacological inhibition (MBM-55), siRNA-mediated knockdown, and plasmid-mediated overexpression. Cellular proliferation was evaluated via CCK-8 and colony formation assays. Transwell migration/invasion assays and flow cytometry were performed to assess the metastatic potential and apoptosis, respectively. The protein levels of FoxM1, NEK2, and AKT/p-AKT were analyzed by Western blotting. Western blot analyses of FoxM1-overexpressing cell lines and RCM-1-treated cells revealed a positive correlation between NEK2 and FoxM1 levels. Co-IP confirmed their interaction. NEK2 knockdown significantly suppressed proliferation, migration, and invasion; enhanced cisplatin sensitivity (reduced the IC<sub>50</sub>); and promoted apoptosis. Conversely, NEK2 overexpression exacerbated malignant phenotypes and decreased chemosensitivity. Mechanistically, NEK2 activation was shown to drive osteosarcoma progression via AKT/p-AKT pathway activation. This study revealed that NEK2 promotes osteosarcoma proliferation, invasion, migration, and chemoresistance while inhibiting apoptosis, likely through AKT/p-AKT signaling.

Interactions between cancer cells, immune cells, stromal cells, and the extracellular matrix within the TME create a dynamic ecosystem that can either promote or hinder tumor growth and spread. The TME plays a pivotal role in either promoting or inhibiting tumor growth and dissemination, making it a critical factor to consider in the development of effective cancer therapies. Understanding the intricate interplay within the TME is crucial for devising effective cancer therapies. Combination therapies involving inhibitors of immune checkpoint blockade (ICB), and/or chemotherapy now offer new approaches for cancer therapy. However, it remains uncertain how to best utilize these strategies in the context of the complex tumor microenvironment. Oncogene-driven changes in tumor cell metabolism can impact the TME to limit immune responses and present barriers to cancer therapy. Cellular and acellular components in tumor microenvironment can reprogram tumor initiation, growth, invasion, metastasis, and response to therapies. Components in the TME can reprogram tumor behavior and influence responses to treatments, facilitating immune evasion, nutrient deprivation, and therapeutic resistance. Moreover, the TME can influence angiogenesis, promoting the formation of blood vessels that sustain tumor growth. Notably, the TME facilitates immune evasion, establishes a nutrient-deprived milieu, and induces therapeutic resistance, hindering treatment efficacy. A paradigm shift from a cancer-centric model to a TME-centric one has revolutionized cancer research and treatment. However, effectively targeting specific cells or pathways within the TME remains a challenge, as the complexity of the TME poses hurdles in designing precise and effective therapies.

This review synthesizes current diagnostic approaches and treatment modalities for cardiac tumors, with a focus on the role of imaging techniques like UCG, CT, MRI, and PET in tumor characterization. Multidisciplinary treatment plans are necessary, including surgical resection for benign tumors, chemotherapy, and radiotherapy for malignant tumors, and novel targeted therapies such as MDM2 inhibitors for selected cases.

In contrast, primary malignant tumors like sarcomas and mesotheliomas exhibit rapid progression and poor prognosis, necessitating aggressive treatment including surgery, chemotherapy, and radiotherapy. Metastatic cardiac tumors occur in approximately 10% of cancer patients at autopsy and are managed according to the treatment plan for the primary malignancy.
