Exploration of the synergistic mechanism of Gegen Qinlian Decoction on Wnt signaling pathway based on an integrated strategy of network pharmacology and transcriptomics

ABSTRACT: Network pharmacology study indicated that Puerarin (PUE), wogonin (WOG), berberine (BER) and glycyrrhetinic acid (GLY) were the active components in GQD and performed synergistic effect on the targets of the Wnt signaling pathway. Pharmacologic research revealed that WOG, BER, GLY performed inhibited effect on SW480 cells and PUE only exhibited effective antitumor activity when combined with GLY. RNA-seq were used to discover synergistic mechanism of PUE-GLY and CTNNB1, CCND1, SMAD4 were identified as synergistic targets inhibited by PUE-GLY. Moreover, mechanism study explored PUE-GLY could affect the Wnt signaling pathway by up-regulated GSK3B and down-regulated CTNNB1 synergistically. Importantly, it showed that GLY could effectively increase the intracellular content of PUE based on HPLC/MS analysis, and this process was achieved by GLY through influencing the targets of membrane’s pathway, such as cell adhesion molecules, focal adhesion and tight junction. Our study revealed multi-target mechanism of GLY, down-regulated CTNNB1 as the material for efficacy and intervene membrane protein (CDH1, CADM1, ITGB2, ICAM1) as courier in the formulae. Moreover, the mechanism of synergistic antitumor action of Puerariae Lobatae Radix (Gegen-Monarch) and Glycyrrhiza Radix et Rhizoma (Gancao-Assistant) on Wnt signaling pathway was explored systematically.

Seminiferous tubule degeneration and infertility in mice with sustained activation of WNT/CTNNB1 signaling in sertoli cells

Project description:To elucidate the role(s) of WNT/CTNNB1 signaling in the testis, transgenic Ctnnb1 tm1Mmt/+;Amhr2 tm3(cre)Bhr/+ mice were generated to obtain sustained activation of the WNT/CTNNB1 pathway in Sertoli cells. Male Ctnnb1 tm1Mmt/+;Amhr2 tm3(cre)Bhr/+ mice were sterile because of testicular atrophy starting at 5 wk of age, associated with degeneration of seminiferous tubules and the progressive loss of germ cells. Sustained WNT/CTNNB1 pathway activation was obtained in Ctnnb1 tm1Mmt/+;Amhr2 tm3(cre)Bhr/+ Sertoli cells. Sertoli cells often exhibited morphological characteristics suggestive of incomplete differentiation that appeared in a manner coincident with germ cell loss, accompanied by an increase in the expression of the immature Sertoli cell marker AMH. Microarray analyses performed on cultured Sertoli cells showed that CTNNB1 induces the expression of genes associated with the female sex determination pathway as well as cell-cycle associated genes . Together, these data suggest that the WNT/CTNNB1 pathway regulates Sertoli cell functions critical to their capacity to support spermatogenesis and to proliferate in the postnatal testis. Sertoli cells were obtained from 3wks-old Ctnnb1(tm1Mmt/tm1Mmt) mice. Cells were infected with adenoviruses to express eGFP or Cre in serum-free medium, and subsequently harvested for RNA extraction. Preliminary experiments demonstrated that an infection efficiency of nearly 100% could be obtained at an MOI of 50 (as determined by analysis of fluorescent signal in Ad-eGFP-infected cells) and that the Ad-Cre virus produced complete recombination of the floxed Ctnnb1 allele after 12 hours. Microaaray analyses were done using triplicate RNA samples from each adenoviral treatment using MouseRef-6 v.2.0 expression BeadChips technology (Illumina, San Diego, CA).

Combination CDC-like kinase inhibition (CLK) and taxane therapy in CTNNB1-mutated endometrial cancer

Project description:SM08502 is a novel pan CDC-like kinase (CLK) inhibitor that targets mRNA splicing and is optimized for Wnt pathway inhibition. Previous evaluation of single agent CLK inhibition (SM04690) demonstrated inhibition of tumor progression and b-catenin/TCF transcriptional activity in CTNNB1-mutant endometrial cancer (EC). In-vitro analysis of SM08502 similarly decreases Wnt transcriptional activity and cellular proliferation while increasing cellular apoptosis. Examining transcriptomic analysis, SM08502 increases pathways involved in RNA metabolism and spliceosome. Examining alternative splicing (AS) events, SM08502 increased differential splicing compared to treatment with paclitaxel. AS regulation is an important post-transcriptional mechanism associated with the oncogenic process in many cancers, including EC.

Transcription profiling time series of the response of Rattus norvegicus colon carcinoma cell line CC531 to treatment with butyrate or aspirin

Project description:Temporal analysis of colon carcinoma cell line CC531 response to 4.5 mM butyrate or 3 mM aspirin. Samples taken at 2, 6, 12, 16 and 24 hours. The CC531 cell line has been widely used to study different aspects of tumor growth and metastasis and provides an excellent experimental platform to develop novel antitumor strategies. To characterize the CC531 model at the molecular level, we screened for mutations in genes covering important signal-transduction pathways that are known to play major roles during colon carcinogenesis, the wnt and the ki-ras signaling pathways. We found both a prototypic beta-catenin (Ctnnb1) mutation (Thr(41)Ile) and a ki-ras (G12D) mutation, providing unambiguous evidence for the constitutive activation of these pathways in CC531 cells. We further established comprehensive gene expression profiles of CC531 cells and investigated the molecular response to 2 antitumor drugs, butyrate and aspirin. Using oligonucleotide microarrays, we screened the expression levels of 7,700 genes and identified a total of 398 genes whose expression was significantly changed upon treatment with butyrate. When using aspirin, 121 genes were significantly altered. Interestingly, 36 genes were regulated by both butyrate and aspirin and 35 of them were regulated in the same direction. We found 7 differentially expressed genes, cyclin D1, cyclin E, c-myc, Fosl1, c-fos, Cd44 and follistatin, which are known targets of the beta-catenin and/or the ras pathway. In all cases, butyrate and aspirin reversed the changes in expression normally found in response to active signaling of these oncogenic pathways.

Quiescence specific β-catenin transcriptional networks in myogenic cells

Project description:Wnt/β-catenin signaling is active during cellular quiescence in muscle myoblasts. Exposure of quiescent myoblasts to Wnt3a led to deregulation of genes associated with both myogenic differentiation and proliferation. Genome-wide analysis Ctnnb1 by ChIP-chip revealed quiescence-specific enrichment on genes of multiple functional classes. The major class of genes bound by Ctnnb1were Wnt pathway genes and all occupied promoters were highly enriched for TCF DNA binding motifs. Cross-comparison of ChIP-Chip with transcriptome data revealed both transcriptional activation as well as repression in Ctnnb1 occupied genes. Inhibition of Ctnnb1-mediated transactivation using shRNA and pharmacological agents led to de-regulation of the quiescence-associated transcriptional profile. Ctnnb1 binding is associated with repression of myogenic genes and cell cycle progression factors while maintaining differential response by these genes to Wnt signaling during quiescence.

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.
