Experimental validation in A549 cells demonstrated that pharmacological inhibition of PLK1 (via GSK461364) effectively suppressed cell proliferation, induced G2/M phase arrest, promoted apoptosis, and led to the accumulation of Cyclin B1 and CDK1 proteins. PLK1 overexpression signifies aggressive disease and poor prognosis in LUAD, mechanistically linked to cell cycle dysregulation and an immunosuppressive microenvironment. Our findings nominate PLK1 as a promising therapeutic target and biomarker, warranting further investigation into PLK1-directed therapies.
The present study developed a PRS using 101 machine learning combination algorithms, which could aid in risk stratification and prognosis for LUAD patients. The candidate drugs and target may provide new insights in the treatment of high PRS group patients.

TRPA1 (Transient Receptor Potential Cation Channel Subfamily A Member 1)
LMNB1 and LMNB2 are prognostic factors for HCC. GSK461364 is a novel therapeutic candidate for HCC, with anti-HCC effects associated with LMNB1/2 suppression.
Furthermore, the PLK1-specific inhibitor GSK461364 synergizes with NB73 to inhibit MM cell growth. Interestingly, NB73 does not sensitize U266 cells, a Venetoclax-resistant t(11;14) MM cell line expressing high FOXM1, to Venetoclax treatment, which is corrected by a new-generation BH3 mimetic Sonrotoclax and ALK inhibitor Ceritinib. Collectively, targeting FOXM1 demonstrates significant potential for enhancing the efficacy of FDA-approved drugs in RRMM. These findings shed new light on the discouraging outcomes of the Phase-III CANOVA study centering Venetoclax with an encouraging molecular clue.

We also identify the molecules targeting these essential hub genes, among which GSK461364 is a promising inhibitor of PLK1, BMS265246, and Valrubicin inhibitors of CDK1 and TOP2A, respectively. Notably, MMP9 emerged as a significant prognostic marker with high expression correlating with poor survival, underscoring its potential for targeted therapy. These findings enhance our understanding of ESCC pathogenesis and highlight promising avenues for treatment.
The results of this study showed a significant increase in the expression level of PLK1, KIF4A, CDCA5, UBE2C, CDT1, SKA3, AURKB, and PTTG1 in TNBC compared to other BC subgroups. These genes show considerable promise as therapeutic targets for the TNBC subgroup.

HER-2 (Human epidermal growth factor receptor 2) • ER (Estrogen receptor) • PGR (Progesterone receptor) • PLK1 (Polo Like Kinase 1) • AURKB (Aurora Kinase B) • PTTG1 (PTTG1 Regulator Of Sister Chromatid Separation, Securin) • CDT1 (Chromatin Licensing And DNA Replication Factor 1) • KIF4A (Kinesin Family Member 4A) • UBE2C (Ubiquitin Conjugating Enzyme E2 C)
PLK1 inhibitors have a synergistic effect with osimertinib on osimertinib-resistant NSCLC cells which indicates that they may have potential clinical value in the treatment of NSCLC patients with osimertinib resistance.
In conclusion, pharmacologic PLK1 inhibition by BI6727 and GSK461364A blocked survival of CCA cells by several mechanisms. Our study provides evidence that BI6727 and GSK461364A could be alternative drugs and have potential implications at the clinical level for CCA therapy.
Current findings suggest that GSK461364A may be a chemotherapeutic agent in patients with gastric cancer. Nevertheless, more research is needed to evaluate GSK461364A as a cancer treatment drug.
Next, we studied metformin (Met) and pioglitazone (Pio)(agents in current oral cancer prevention studies) combined with G2/M blockade inhibitors, MK1775 (Wee1 kinase inhibitor) and GSK461364 (PLK inhibitor) in FA1s. Differentiation was indicated by upregulation panKeratin and Transglutaminase-3. We conclude combination therapies with high interest agents in FA-associated oral cancer can be performed in 3D culture systems and might confirm drug mechanisms of action, thus augmenting other standard methods of cancer drug evaluation and screening (e.g. cell proliferation and clonogenicity).
Additionally, high-risk patients generally exhibited higher response to chemotherapeutic agents (cisplatin, etc.). We also predicted several small molecule compounds (GSK461364, KX2-391, etc.) for treating this subset. Accordingly, this cuproptosis-relevant lncRNA signature offers an efficient approach to identify and characterize diverse prognosis, genomic alterations, and treatment outcomes in LUAD, thus potentially assisting personalized therapy.
