The mechanism by which STAG2 acts in a pro-oncogenic manner in bladder cancer remains unknown. Due to this elusive role of STAG2, targetable vulnerabilities based on STAG2 expression have not yet been identified. In the current study, we sought to uncover therapeutic vulnerabilities of muscle invasive bladder cancer cells based on the expression of STAG2. Using CRISPR-Cas9, we generated isogenic STAG2 wild-type (WT) and knock out (KO) cell lines and treated each cell line with a panel of 312 anti-cancer compounds. We identified 100 total drug hits and found that STAG2 KO sensitized cells to treatment with PLK1 inhibitor rigosertib, whereas STAG2 KO protected cells from treatment with MEK inhibitor TAK-733 and PI3K inhibitor PI-103. After querying drug sensitivity data of over 4500 drugs in 24 bladder cancer cell lines from the DepMap database, we found that cells with less STAG2 mRNA expression are more sensitive to ATR and CHK inhibition. In dose-response studies, STAG2 KO cells are more sensitive to the ATR inhibitor berzosertib, whereas STAG2 WT cells are more sensitive to PI3K inhibitor PI-103. These results, in combination with RNA-seq analysis of STAG2-regulated genes, suggest a novel role of STAG2 in regulating PI3K signaling in bladder cancer cells. Finally, synergy experiments revealed that berzosertib exhibits significant synergistic cytotoxicity in combination with cisplatin against MIBC cells. Altogether, our study presents evidence that berzosertib, PI-103, and the combination of berzosertib with cisplatin may be novel opportunities to investigate as precision medicine approaches for MIBC patients based on STAG2 tumor expression.</p>","PeriodicalId":19489,"journal":{"name":"Oncogenesis","volume":"14 1","pages":"4"},"PeriodicalIF":5.9,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11873148/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143537380","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To date, the decreasing trend in mortality rates related to the most common cancers has contributed to making pancreatic cancer a serious public health problem. In the last few years, scientific research has led to many advances in diagnostic approaches, perioperative management, radiotherapy techniques, and systemic therapies for advanced disease, but only with modest incremental progress in PC patient outcomes. Most of the causes of this high mortality are, unfortunately, late diagnosis and an important therapeutic resistance; for this reason, the most recent high-throughput proteomics technologies focus on the identification of novel biomarkers and molecular profiling to generate new insights in the study of PC, to improve diagnosis and prognosis and to monitor the therapies progress. In this work, we present and discuss the integration of results from different revised studies on protein biomarkers in a global proteomic meta-analysis to understand which path to pursue scientific research. In particular, cancer signaling, inflammatory response, and cell migration and signaling have emerged as the main pathways described in PC, as well as scavenging of free radicals and metabolic alteration concurrently highlighted new research insights on this disease. Interestingly, from the study of upstream regulators, some were found to be shared by collecting data relating to both biological fluid and tissue biomarkers, side by side: specifically, TNF, LPS, p38-MAPK, AGT, miR-323-5p, and miR-34a-5p. By integrating many biological components with their interactions and environmental relationships, it's possible to achieve an in-depth description of the pathological condition in PC and define correlations between concomitant symptoms and tumor genesis and progression.

Targeted delivery of therapeutic molecules offers a promising solution. Given that PDAC is marked by a desmoplastic reaction with extensive aberrant protease activity, protease-dependent targeted delivery could minimize off-target toxicities and is of increasing interest. The efficacy of targeted delivery hinges on the specificity of the substrates used; insufficient specificity can lead to off-target effects, reducing the advantage over non-targeted methods. Here, we employ an unbiased library approach to screen over 7 million peptide substrates for proteolytic cleavage by PDAC cell lysates, identifying 37 substrates enriched by at least 500-fold after three rounds of selection. As systemically administered targeted delivery depends on the absence of substrate cleavage in circulation, the peptide library was also screened against whole blood lysates, and enriched substrates were removed from the PDAC-enriched dataset to obtain PDAC-specific substrates. In vitro validation using FRET-peptides showed that 13 of the selected 15 substrates are cleaved by a panel of PDAC cell line lysates. Moreover, evaluation against healthy murine organ and human blood lysates to assess off-target cleavage revealed that the identified substrates are indeed PDAC-specific and that several substrates may be superior with respect to PDAC specificity over the CAPN2-responsive substrate, which has recently shown preclinical potential in targeted therapy, but future animal models should address the potential superiority.

The recent works indicated that both the pathological SS18-SSX tumorigenic fusion and the corresponding intrinsic physiological SS18 protein can form condensates but appear to have disparate properties. The underlying regulatory mechanism and the consequent biological significance remain largely unknown. We show that the physical properties of oncogenic fusion protein SS18-SSX condensates within cells undergo alterations compared to the proto-oncogene protein SS18. By small-molecule screening and mutant assay, we identified the recognition of H2AK119ub histone modification could account for the distinctive properties of SS18-SSX1 condensates. Notably, we show that SS18-SSX1 condensates have impact on SS18 condensates and hijack that in a phase separation manner, resulting in the relocation of protein SS18 to the H2AK119ub modification targeted by SS18-SSX1. Consequently, this leads to the downregulation of tumor suppressor genes occupied by SS18 physiologically, like CAV1 and DAB2. These results reveal the underlying mechanism of genomic disorder and tumorigenesis caused by the remodeling of oncoprotein SS18-SSX1 condensates at the macroscopic level.</p>","PeriodicalId":19489,"journal":{"name":"Oncogenesis","volume":"13 1","pages":"38"},"PeriodicalIF":5.9,"publicationDate":"2024-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11519567/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142522592","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
