Sonic Hedgehog inhibitors cyclopamine and GANT61 effect on HT-29 cells

ABSTRACT: Analysis of gene expression levels in response to inhibition of Hh signaling in HT-29 cells using a cDNA microarray technique. Microarray analyses revealed that different genes after treatment with both cyclopamine (an antagonist of SMO) and GANT61 (a specific, small-molecular molecule inhibitor of Glis).

Project description:Analysis of gene expression levels in response to inhibition of Hh signaling in hepatocellular cancer cells using a cDNA microarray technique. Microarray analyses revealed that 136 genes were up-regulated and 335 gene were down-regulated after treatment with both cyclopamine (an antagonist of SMO) and GANT61 (a specific, small-molecular molecule inhibitor of Glis).

Sonic Hedgehog inhibitor cyclopamine effect on JAR cells

Project description:Physiologically, trophoblast progenitor cells differentiate into placental villous cytotrophoblast cells (CTBs). CTBs either differentiate into invasive lineage to yields extravillous cytotrophoblast cells (EVTs), or undergo cell fusion lineage to yields syncytiotrophoblast cells (STBs)，Sonic hedgehog (Shh) together with indian hedgehog (Ihh) and desert hedgehog (Dhh) consist of ligand of hedgehog signaling pathway, which plays pivotal roles in regulating cell proliferation, cell differentiation, organogenesis and development, even involving in tumorigenesis and progression. previous study had summarized and indicatedthat hedgehog proteins played important roles in regulating hematopoiesis, vasculogenesis and angiogenesis during embryogenesis and development. Herein, we investigate the effect of the Sonic Hedgehog morphogen inhibitor Cyclopamine on JAR cells

Comparative analysis of murine Th17 cell transcriptomes in the presence of Smo inhibitor cyclopamine or carrier control

Project description:T helper 17 (Th17) cells play a key role in barrier protection against fungal and bacterial pathogens but are also pathological drivers of many inflammatory diseases. We find that Hh signaling inhibition through Smoothened inhibitor cyclopamine selectively inhibits Th17 lineage differentiation but not the development of Th1, Th2, or iTreg CD4+ Th cells. In these experiments we analysed the transcriptomes of Th17 cells that had been polarized in the presence of cyclopamine or carrier control to profile the global transcriptome of Th17 cells in which the Hh pathway had been blocked. The aim of this analysis was to identify the target genes downstream of Smo that may be important for Th17 polarisation.

Zebrafish embryos exposed to the model hedgehog pathway inhibitor cyclopamine, as well as to the potential hedghog pathway disrupters SANT-2 and GANT-61.

Project description:The hedgehog (Hh) signaling pathway is important for various developmental processes during embryogenesis and for homeostasis of adult tissue in vertebrates. Aberrant signaling results in severe birth defects and malignancies, respectively. The small molecules SANT-2 and GANT-61 were identified as potential Hh-pathway inhibitors in a reporter gene assay (Shh-light II cells). We aimed to analyze the effects of these compounds on the gene expression level in zebrafish embryos in comparison with the well known Hh-pathway inhibitor cyclopamine. Zebrafish embryos were treated with Ethanol (0,1%) (control), 10 µM Cyclopamine (C), 10 µM SANT-2 (S), and 10 µM GANT-61 (G), for 24 h (0.5 - 24 hpf), respectively; all in 5 independent replicates with 100 zebrafish embryos per treatment. Total RNA was extracted and processed as recommended by Agilent. One color arrays were used and data is given as normalized log2 of the gprocessed signals.

Inhibition of Medulloblastoma growth by a sonic hedgehog (SHH) inhibitor

Project description:Aberrant activation of the Hedgehog (Hh) signaling pathway is implicated in the pathogenesis of many cancers, including medulloblastoma and basal cell carcinoma (BCC). In this study, using neonatally irradiated Ptch1+/- mice as a model of Hh-dependent tumors, we investigated the in vivo effects of MK-4101, a novel SMO antagonist, for treatment of medulloblastoma and BCC. Results clearly demonstrate a robust antitumor activity of MK-4101, achieved through the inhibition of proliferation and induction of extensive apoptosis in tumor cells. Of note, beside antitumor activity on transplanted tumors, MK-4101 was highly efficacious against primary medulloblastoma and BCC developing in the cerebellum and skin of Ptch1+/- mice. By identifying the changes induced by MK-4101 in gene expression profiles in tumors, we also elucidate the mechanism of action of this novel, orally administrable compound. MK-4101 targets the Hh pathway in the tumor cells, showing the maximum inhibitory effect on Gli1 activity. MK-4101 also induced deregulation of cell cycle and block of DNA replication in tumors. Members of the IGF and Wnt signaling pathways , were among the most highly deregulated genes by MK-4101, suggesting that the interplay among Hh, IGF and Wnt is crucial in Hh-dependent tumorigenesis. Altogether, the results of this preclinical study support a therapeutic opportunity for MK-4101 in the treatment of Hh-driven cancers, also providing useful information for combination therapy with drugs targeting pathways cooperating with Hh oncogenic activity. Gene expression data was generated (in replicates) from Medulloblastoma allografts collected at various time points and following low (40mpk) or high (80 mpk) or vehicle single dose (QD) or mutiple dose (BID) treatment with a SHH pathway inhibitor.

Engineering endochondral ossification using Sonic Hedgehog for bone regeneration

Project description:Endochondral ossification (EO) is the natural route for the regeneration of large and mechanically challenged bone defects. Regeneration occurs via a fibrocartilagenous phase which turns into bone upon vascularization and the formation of a transient collagen type X extra cellular matrix. These two critical initiator of EO are mediated by Hedgehog proteins. We investigated a tissue engineering approach using Sonic Hedgehog (Shh) as a pleiotropic factor regulating the in vitro formation of a vascularized bone tissue precursor for in vivo endochondral bone formation. The tissue engineered graft was formed using human mesenchymal stem cells and prevascularized using human umbilical vein endothelial cells. We show that Shh induced, in vitro, the maturation of the engineered vascular network along with the expression of collagen type X which resulted, in vivo, in an improved vascularization and the rapid formation of large amounts of osteoids through EO. Osteoids further matured into, currently unmatched, clinically relevant amount of lamellar bone including osteoclasts, bone lining cells and bone marrow-like cavities. This result suggests that Hh is a master regulator of EO allowing for the formation of complex tissues with considerable therapeutic potential for bone regeneration. The effect of Cyclopamine on expression of Hedgehog, angiogenesis and axon guidance marker genes was analyzed by seeding a coculture of 92% hMSCs and 8% huvEC supplemented or not in cyclopamine, for 12 days
