Global sensitivity analysis identified compensatory feedback, tumor proliferation rate, and PI3K-mTOR crosstalk as key determinants of tumor response. This novel QSP application exemplifies an innovative bottom-up modeling approach to support patient selection and dosing strategies for future clinical studies.

Moreover, 9 transcription factors (TFs) (like STAT1), 69 key microRNAs (miRNAs) (like hsa-miR-361-3p), and 78 long non-coding RNAs (lncRNAs) (like NEAT1) were found to have relationships with potential biomarkers, and potential biomarkers had stable binding affinity with adenosine diphosphate (ADP) and lonafarnib...Importantly, RT-qPCR confirmed higher expression of HSPA8, LMNA and SERPINH1 in CS patients. The findings suggested that HSPA8, LMNA and SERPINH1 might offer novel insights for the development of targeted therapies for CS associated with angiogenesis and ISR.

Farnesyltransferase (FTase) inhibitors (FTIs), such as tipifarnib, inhibit HRAS membrane localization and blunt RAS effector signaling, leading to an antitumor effect in HRAS-mutant FN-RMS preclinical models...Co-targeting FTase and MEK restrained tumor progression and induced terminal myogenic differentiation. These findings highlight an effective combinatorial strategy and support its preclinical translation for patients with HRAS-mutant RMS.

Further, the addition of KO-2806 rescued sensitivity of progressing tumors to the pan-RAS inhibitor RMC-6236. These results establish mTORC1 as an important mediator of escape from RAS inhibition and highlight KO-2806 as a promising RAS companion inhibitor in patients with prior RAS inhibitor exposure.

Furthermore, dapansutrile exhibits synergistic effects when combined with agents such as lonafarnib or immune checkpoint inhibitors, enhancing anti-inflammatory and anti-tumor responses. This review consolidates evidence on dapansutrile's molecular mechanisms, therapeutic applications, and biosafety, highlighting its potential as a novel, well-tolerated, and versatile anti-inflammatory agent. Future research should focus on optimizing its delivery, particularly to the central nervous system, and leveraging artificial intelligence to predict effective drug combinations.

In this study, 8 SUMO-ylation related prognostic genes were identified in BRCA, namely GPC1, CAPZA1, NUDCD1, MTDH, COX7A1, PLK3, FAM43A and CEBPD, offering fresh perspectives on the prognosis of BRCA.

However, MD simulations confirmed that both essential oil compounds exhibit binding stability comparable to that of Tipifarnib. Finally, α-humulene epoxide II and bornyl acetate from S. cumini exhibit favorable drug-like properties, high predicted safety margins, and a lack of organ-specific toxicity, underscoring their suitability for further drug development.

Our findings demonstrate that FTIs Lonafarnib and Tipifarnib impair MVM, highlighting the essential role of farnesylation in biomineralization.

The hub gene CCND1 and its targeting drug candidate Tipifarnib may contribute to PTC treatment.

Lamins have also been shown to be dysregulated in a multitude of cancers, and research has uncovered a diabolical role of lamins in oncogenesis. The understanding of laminopathies and dysregulation of lamins resulting in disorders is critical in developing novel therapeutic strategies through drug repurposing and epigenetic modulation to curb the burden of the diseases.

The farnesyltransferase inhibitor tipifarnib blocked mutant HRAS-PI3K signaling and synergized with MEK inhibitors in HRAS-mutated cells, whereas KRASG12C inhibitors blocked mutant KRAS-MEK signaling and synergized with PI3K inhibitors in KRASG12C-mutated cells. Synergy was abolished in MEFs lacking all RAS proteins and in cancer cell lines in which nonmutated RAS family members were deleted. Our data highlight the critical role of wild-type RAS family members in supporting mutant RAS signaling and its importance as a therapeutic cotarget in RAS-mutated cancers.
