Sonidegib and vismodegib are synthetic mimetics of hedgehog pathway inhibitors that are indicated for many subtypes of advanced BCC. After eight months of hedgehog pathway inhibitor (HHI) therapy, the patient reported dramatic improvements in his BCC and complete regression of smaller BCCs previously noted on his upper extremities. The patient reported only minor adverse events including hair thinning, weight loss, and rapidly growing nails.

Patidegib Topical Gel warrants further clinical development.

Overall, by integrating network and structural pharmacology with molecular modeling, we determined two complementary strategies with the potential to annihilate the AML network, one in the form of repurposable drug combinations and the other as a de novo synthesized triple-targeting agent. These target-drug interactions could be prioritized for preclinical and clinical testing toward precision medicine for AML.

A chemotherapy regimen includes a combination of high-dose Methotrexate (MTX), doxorubicin, and cisplatin...CUR and MTX combined determined a β-Catenin decrease and a trend toward reducing NF-kB and matrix metalloproteinases (MMP-2 and MMP-9). Our findings suggest CUR as a support to OS treatment, improving outcomes and reducing the adverse effects of current therapies.

Among them, N-(4-((dimethylamino)methyl)phenyl)-4-((4-(pyridin-3-yl)pyrimidin-2-yl)amino)benzamide (B31) emerged as the most potent analog following screening with a Gli luciferase reporter assay, competing with cyclopamine in the binding site of Smo protein...Moreover, B31 significantly regressed subcutaneous tumors formed by BxPC-3 cells in nude mice without inducing toxic effects. These results underscore the enhanced efficacy of B31 in the PC model and offer a new avenue for developing effective Hh pathway inhibitors for clinical PC treatment.

BCC is characterized by low immunogenicity, which hinders immune response and contributes to treatment challenges. Enhanced understanding of the epidemiology, risk factors, and pathogenesis of locally advanced BCC, along with the development of targeted therapeutic approaches such as hedgehog pathway inhibitors, is essential for effectively managing this prevalent carcinoma and improving patient outcomes.

These findings suggest that Oxy210 could be a drug candidate for targeting both NASH and atherosclerosis, as well as chronic inflammation associated with the manifestations of metabolic syndrome.

Our disulfidptosis-related lncRNA signature comprised of AL157871.2, HCP5, AC027348.1, AL109615.3, AL928654.1, LINC02585, and AC011445.1 could serve as a prognostic biomarker and guidance to therapy response for OC patients.

Awareness of the clinicopathologic spectrum of SUFU-associated basaloid neoplasms is important for dermatologists and dermatopathologists because many (although not all) of these lesions are indolent and do not require aggressive surgical treatment. Importantly, because SUFU lies downstream of the protein smoothened, vismodegib and other smoothened inhibitors are unlikely to be effective therapies in this subset of patients.

However, targeted therapies such as sonidegib and vismodegib - sonic hedgehog pathway inhibitors - have emerged that have been approved for treating BCC, as have anti-PD1 immunotherapies, such as cemiplimab, with their success likely based on the high tumor mutational burden seen in some of these tumors. Epidermal growth factor receptor (EGFR) inhibitors also serve a role in treating this condition as well. Molecular studies on metastatic/advanced BCC and other rare malignancies may inform treatment therapeutic decisions.

Changes in tumor-secreted factors resulted in polarization of THP-1 monocytes toward a proinflammatory phenotype, characterized by increased CD14 and CD40 surface marker expression. We therefore propose M-CSF as a novel target of Hedgehog inhibition with potential future applications in altering the immune microenvironment in addition to its known roles in reducing tumor-induced bone disease.

Patients 1, 3, and 4 displayed a clinical response to debulking followed by vismodegib, whereas patient 2 was lost to follow-up after debulking. These findings suggest that surgical manipulation of LaBCCs is correlated with molecular alterations in signaling pathways associated with cellular reprogramming.

Here, we developed a nanocomposite hydrogel for the sustained co-delivery of bioactive magnesium ions, anti-PD-L1 antibody (αPD-L1), and hedgehog pathway antagonist vismodegib, to eradicate residual tumor cells while promoting bone regeneration post-surgery...After 21 days, the expression levels of ALP, COL1, RUNX2, and BGLAP in the Vis-αPD-L1-Gel group were approximately 4.1, 5.1, 5.5, and 3.4 times higher than those of the control, respectively. We believe that this hydrogel-based combination therapy offers a potentially valuable strategy for treating osteosarcoma and addressing the tumor-related complex bone diseases.

While mammary tumors developed in MMTV-PyMT/CerS4-/- were highly metastatic, targeting the Shh/PD-L1 axis using sonidegib and anti-PD-L1 antibody vastly decreased tumor growth and metastasis, consistent with the inhibition of PD-L1 internalization and Shh/Wnt signaling, restoring anti-tumor immune response. These data, validated in clinical samples and databases, provide a mechanism-based therapeutic strategy to improve immunotherapy responses in metastatic TNBCs.

However, Vis enhanced PTX-induced Bak activation, leading to mitochondrial damage, ROS accumulation, and subsequent apoptosis. Our findings suggest that the combination of Vis and PTX could be a potential therapeutic strategy to increase PTX sensitivity of EGFR-mutant NSCLC.

Here we report in detail the management of three complex advanced BCC (aBCC) after treatment failure with vismodegib...However, despite the high tumor mutational burden of aBCCs, immunotherapy does not always lead to a long response. Rechallenge or combining treatment of hedgehog inhibitors and PD-1 inhibitors by parallel or alternating cycles may be a strategy to lengthen the treatment response.

Notably, targeting SHH signaling with vismodegib exhibited promising potential in mitigating scar formation by reversing the effects of enhanced OXPHOS and M2 polarization in macrophages. In conclusion, this study underscores the critical roles of macrophage metabolism, particularly OXPHOS, efferocytosis and SHH signaling in cutaneous scar formation. Understanding these mechanisms provides new avenues for potential interventions and scar prevention strategies.

The SHH signaling pathway-related factors smoothened and glioma-associated oncogene homolog-1 were increased with the intervention of SRT1720, while cyclopamine (a specific inhibitor of the SHH signaling pathway) reversed these effects. These findings suggest that SIRT1 protects from ICH by altering BBB permeability and tight junction expression levels. This process is associated with the SHH signaling pathway, suggesting that SIRT1 may be a potential therapeutic target for ICH.

Our results suggest that patients with BLCA have a greater sensitivity to four drugs (dasatinib, pazopanib, erismodegib and olaparib). Our study provides new insights into the TME, key signalling pathways, genome, and potential therapeutic targets of BLCA, with future guidance for immunotherapy and targeted precision drugs.

To obtain insights into their mode of inhibition, we structurally and functionally characterized USP28 in the presence of the three different inhibitors AZ1, Vismodegib and FT206...Furthermore, a key glutamate residue at position 366/373 in USP28/USP25 plays a central structural role for pocket stability and thereby for inhibition and activity. Obstructing the inhibitor-binding pocket by mutation of this glutamate may provide a tool to accelerate future drug development efforts for selective inhibitors of either USP28 or USP25 targeting distinct binding pockets.

Interestingly, ZMYND8 is found to counteract the inhibitory effects of Cyclopamine that block the upstream SHH pathway protein SMO, resulting in enhanced neurite formation in neuroblastoma cells following their treatment with ATRA. These results indicate that ZMYND8 is an epigenetic regulator of the SHH signaling pathway and has tremendous therapeutic potential in ATRA-mediated differentiation of neuroblastoma.

Chemotherapy-induced hair loss (CIA) occurs in up to 65% of cases. Anagen effluvium is observed as early as 1-3 weeks after the start of treatment and is reversible in most cases. Alopecia associated with inhibitors of the Sonic Hedgehog signaling pathway (HHIA) such as vismodegib or sonidegib are observed in up to 60% of cases. They are characterized by telogen effluvium. BRAF or immune checkpoint inhibitors lead significantly less frequently to alopecia (BRAFA, CPIA). According to taxane-based chemotherapy protocols, scalp cooling can help to prevent higher-grade CIA. If CIA or other forms of alopecia are expected, early contact with self-help organizations and early prescriptions for wigs should be offered.

Our model could precisely predict the prognosis, immune status and drug sensitivity of OC patients.

Additionally, the median half maximal inhibitory concentration (IC50) of bexarotene, cyclopamine, etoposide, and paclitaxel in LYPD3 high group was significantly lower than that in LYPD3 low group. LYPD3 is involved in many BPs of LC, such as regulating immune cell infiltration and affecting prognosis. Therefore, LYPD3 may have potential value as a biomarker for prognosis and immunotherapy in LC.
