As a risk factor, RAB7A relating to poor prognosis was identified in our study, and was a potential target for therapeutic agents such as PLX4720 and PD-0325901, while OXSM was the opposite. The 5-DRGs prognostic model can be used to assess the prognosis of patients with CC, and reflect the characteristics of their immune microenvironment. With RAB7A and OXSM as key determinants, this model provides a clinically applicable framework for risk stratification and personalized treatment guidance.

While mitogen-activated protein kinase kinase (MEK) inhibitors, selumetinib and mirdametinib, can reduce tumor volume, surgical resection remains the primary treatment for immediate debulking and symptom relief. These results provide the first evidence that ECM stiffening, such as that arising from postsurgical remodeling, directly drives pNF1 progression and therapeutic resistance. Our findings highlight mechanobiology as a key regulator of tumor behavior and support targeting ECM mechanics to improve clinical outcomes in NF1 patients.

The following ten drugs received FDA approval in 2025 - avutometinib (inhibiting MEK1/2 in serous ovarian carcinomas), defactinib (blocking FAK in low grade serous ovarian carcinomas), delgocitinib (antagonizing the JAK family in hand eczema), mirdametinib (inhibiting MEK1/2 in type I neurofibromatosis), remibrutinib (blocking BTK in chronic spontaneous urticaria), rilzabrutinib (antagonizing BTK in chronic immune thrombocytopenia), sunvozertinib (blocking mutant exon 21 insertion EGFR NSCLC), taletrectinib (inhibiting mutant ROS1 in NSCLC), vimseltinib (blocking CSF1R in tenosynovial giant cell tumors), and zongertinib (antagonizing mutant HER2 in NSCLC). This article summarizes the physicochemical properties of all 94 FDA-approved small molecule protein kinase inhibitors including the molecular weight, number of hydrogen bond donors/acceptors, ligand efficiency, lipophilic efficiency, polar surface area, and solubility. A total of 45 of the 94 FDA-approved drugs have a least one Lipinski rule of five violation.

Drug sensitivity screening identified six small molecules (PD0325901, ERK-6604, paclitaxel, ribociclib, TAF1, and lapatinib) that targeted SLC12A5-related pathways. Crucially, multivariate Cox regression analysis confirmed that SLC12A5 was an independent prognostic factor (HR p = 0.04). This study established SLC12A5 as a novel biomarker for GBM, uniquely bridging molecular dysregulation, edema pathogenesis, and radiomics with implications for prognosis and targeted therapy.

In vitro validation narrowed compounds of interest to raltitrexed, alisertib, GTX-007, LY315920, and PD0325901. Treatment with alisertib leads to decrease in H2AK119ub and shift in the immune tumor microenvironment. Alisertib efficacy in HGSC is dependent on functional CBX2 and cell target engagement confirms selectivity for CBX2, supporting that alisertib activity involves CBX2 inhibition.

Nf1 OPG mice were treated with standard of care (SOC; carboplatin), clinically evaluated (everolimus, mirdametinib), and investigational (pexidartinib, HBS-101, lamotrigine) drugs during the period of most rapid tumor growth (6-12 weeks of age). This referential preclinical study design affords direct head-to-head comparisons of investigational therapies relative to SOC treatment using clinically meaningful outcomes (OPG growth and RNFL thickness). Using this strategy, lamotrigine emerged as the most promising therapy for limiting tumor progression and vision loss in Nf1-OPG mice, relevant to clinical translation for children with NF1-OPG.

OCS is the most aggressive, drug-resistant gynaecological malignancy and eribulin-based combination therapies, particularly triple combination therapies, have the potential to improve patient outcomes.
