This study assessed the apoptotic and antiproliferative effects of the Polo-like kinase 1 inhibitor MLN0905, alone and in combination with lenalidomide, in an MM cell line. The AMO1 human MM cell line was treated with various doses of lenalidomide, MLN0905, or their combination. Cell viability was assessed via the MTT assay, and apoptosis was quantified via Annexin V/propidium iodide staining. The effects of treatment on BCL2, p21, and PUMA gene expression were evaluated through quantitative real-time polymerase chain reaction. The IC50 values were 50.61 μM for lenalidomide and 54.27 nM for MLN0905, indicating dose-dependent cytotoxic effects. When 30 μM lenalidomide was combined with 50 nM MLN0905, the percentage of apoptotic cells increased to 51.31%. The SynergyFinder platform identified optimal synergy at 40 μM lenalidomide plus 50 nM MLN0905. MLN0905 significantly reduced p21, PUMA, and BCL2 mRNA levels, whereas lenalidomide increased p21 and PUMA mRNA expression and decreased BCL2 expression. The combination treatment notably increased p21 expression and significantly reduced BCL2 levels, with no marked change in PUMA mRNA. This study revealed that MLN0905 significantly affects AMO1 cell survival, reducing the mRNA expression of genes involved in apoptosis and the cell cycle in a dose-dependent manner. Furthermore, the combination of lenalidomide and MLN0905 synergistically decreases cell survival and induces apoptosis in AMO1 cells. The altered expression of apoptotic genes highlights the potential of this drug combination for future multiple myeloma research.</p>","PeriodicalId":14513,"journal":{"name":"Investigational New Drugs","volume":"43 2","pages":"348-356"},"PeriodicalIF":3.0,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144004972","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we found that CTI-2, a novel inhibitor of perinucleolar compartment (PNC), has potential anti-AML activity with a favorable safety profile. CTI-2 induced a greater degree of apoptosis in FLT3-ITD mutant AML cells compared to AML cells with wild-type FLT3 mainly through the intrinsic apoptotic pathway. Furthermore, MK2 and Pim-1 were identified as potential targets of CTI-2 through molecular docking analysis. CTI-2 decreased both the overall expression level and the phosphorylation of c-Myc, which are regulated by MK2 and Pim-1, respectively. Notably, CTI-2 exhibited a more substantial inhibitory effect on c-Myc in FLT3-ITD mutant cells, which may contribute to the enhanced efficacy of CTI-2 in this specific subset of AML.

While antibody-drug conjugates (ADCs) targeting HER2, such as T-DM1 and T-Dxd, have shown remarkable antitumor effects in clinical responses, their effectiveness is constrained by drug resistance. EGFR amplification or high expression is one of the factors that lead to resistance against HER2-targeted ADCs. Likewise, the amplification of HER2 may lead to the development of resistance to EGFR-targeted therapies. To overcome these challenges, we, therefore, developed a bispecific antibody (B2C4) that targets HER2 and EGFR. B2C4 exhibited strong binding affinity and internalization activity in tumor cells with high expression of HER2 and EGFR, as well as in those with high expression of either target. B2C4 was then conjugated with vc-MMAE to create a bispecific ADC (B2C4-MMAE) with an average DAR of 4.05. By effectively engaging both arms of the bispecific ADC, B2C4-MMAE demonstrated significant antitumor activity in tumor cells and animal models that were unresponsive HER2- or EGFR-targeted ADCs.
