However, the contributions of ubiquitination-related genes in CRC remain unclear. This study conducted a detailed analysis of gene expression profiles associated with ubiquitination in CRC, evaluating 1006 genes across 46 pathways. By comparing CRC tissues to adjacent normal tissues, we identified differentially expressed genes and developed a ubiquitination-related pathway gene signature (URPGS) using LASSO regression analysis on genes with prognostic significance. The prognostic capability of the URPGS was validated in independent cohorts, and its associations with clinical characteristics, including post-chemotherapy survival outcomes, were examined. Machine learning techniques identified HSPA1A as a key gene relevant to CRC both in vitro and in vivo. Our analysis revealed 307 differentially expressed ubiquitination-related genes, with 24 significantly associated with patient prognosis. The developed 14-gene URPGS exhibited strong prognostic value, effectively stratifying patients into high-risk and low-risk groups for overall survival. The URPGS correlated with advanced clinical stages, lymph node metastasis, and recurrence, with higher scores linked to poorer post-chemotherapy survival outcomes. Knockdown of HSPA1A significantly inhibited CRC cell proliferation, migration, and invasion in vitro, as well as tumor growth and metastasis in vivo. This research establishes a novel URPGS that effectively predicts prognosis and chemotherapy outcomes in CRC, enhancing our understanding of ubiquitination's role and suggesting personalized treatment strategies.</p>","PeriodicalId":18433,"journal":{"name":"Medical Oncology","volume":"42 4","pages":"123"},"PeriodicalIF":2.8,"publicationDate":"2025-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11922989/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143663966","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we found that the high expression of ADAM9 in gastric cancer tissues was associated with a variety of clinicopathological factors and poor prognosis in patients. Gastric cancer cells with high ADAM9 expression reduced sensitivity to Cisplatin, decreased DNA damage, increased expression of ATM and CHK2, the key proteins in DNA damage repair pathway, and improved cancer cells survival rate. Further studies showed that the expression of ADAM9 was selectively interfered with gastric cancer cells, the expression levels of ATM and CHK2 were decreased, while the expression of damage protein γ-H2AX was significantly increased, the degree of DNA damage was increased, and the sensitivity of gastric cancer cells to Cisplatin was significantly enhanced. It is suggested that ADAM9 is involved in Cisplatin resistance in gastric cancer cells, and its mechanism is related to the activation of ATM-CHK2 pathway in DNA damage repair.

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.

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.

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.
