Accordingly, current targeted therapies for locally advanced, unresectable, or metastatic BCC focus on SMO inhibition, using orally administered drugs such as vismodegib and sonidegib. To our knowledge, this is the first report documenting a sonidegib resistance mechanism in BCC that is independent of HH pathway mutations. This case highlights the complexity of resistance mechanisms to HH inhibitors and underscores the critical need for comprehensive molecular tumor profiling prior to initiating targeted therapy.

The linker-payload system was stable in plasma yet released gradually cyclopamine at pH 5.5. These results suggest the feasibility of using natural products as payloads for the construction of ADCs to inhibit HH signalling in cancer cells.

Pharmacological inhibition of GLI1 with the SMO inhibitor vismodegib suppressed HSC activation in vitro and reduced fibrosis and tumor growth in vivo. These findings indicate that SPP1 promotes intratumoral fibrosis and HCC progression through the SPP1-CD44-GLI1 axis, highlighting its potential as a prognostic biomarker and therapeutic target. Inhibition of SPP1-CD44-Hedgehog signaling may provide a promising strategy to mitigate fibrosis and improve HCC patient outcomes.

This functional defect is rescued by treatment with Vismodegib, a TFE3-inducing drug. Our findings reveal lysosome-mediated extracellular protein catabolism as an important metabolic pathway supporting T cell immunity.

Organoid-based drug sensitivity testing was conducted using vismodegib, a Sonic Hedgehog (SHH) pathway inhibitor...We established the first PDO models of chondrosarcoma that faithfully recapitulate key tumor features. These models provide a valuable preclinical platform for dissecting molecular pathogenesis and for advancing the development of targeted therapeutic strategies in this intractable malignancy.

Taken together, these findings establish a mechanistic foundation for a proposed therapeutic optimization strategy: Reducing vismodegib dosing while leveraging its inhibition-driven elevation of simvastatin systemic/tissue exposure, thereby mitigating dose-limiting skeletal toxicity while maintaining anti-tumor efficacy. This mechanism-based strategy provides a clinically actionable framework for pediatric medulloblastoma with urgent unmet therapeutic needs.

Rarely, this condition is related to a suppressor of fused gene mutation, which occurs downstream from Smoothened, and is unresponsive to Smoothened inhibitors including vismodegib and sonidegib. Genetic testing was negative for patched 1 and patched 2 mutations but positive for a heterozygous suppressor of fused mutation. Patients with basal cell nevus syndrome should be treated with surgical excision, counseled on sun protection, screened and monitored for complications, and treated with vismodegib (if associated with patched 1 mutation) or itraconazole (if associated with suppressor of fused mutation).

Solasodine inhibited the proliferation of AGS and MKN74 gastric cancer cells and regulated cell cycle (Cyclin D1 and p27) and apoptosis (Bax and Bcl-2) markers in a dose-dependent manner, consistent with the Gli1/2 inhibitor Gant61 but not the Smo inhibitor vismodegib...Moreover, solasodine inhibited Gli1 rather than Smo expression in Hh signaling overexpressed Ptch (-/-) MEF cells. Our findings demonstrate that solasodine inhibits gastric cancer proliferation by targeting Hh/Gli1 signaling, underscoring its potential as a potent agent for prevention and/or inhibition of gastric cancer.
