PI3K/AKT/mTOR and Sonic hedgehog pathways cooperate together to inhibit human pancreatic cancer stem cell characteristics and tumor growth

Project description:Cancer stem cells (CSCs) play major roles in cancer initiation, progression, and metastasis. It is evident from growing reports that PI3K/Akt/mTOR and Sonic Hedgehog (Shh) signaling pathway are aberrantly reactivated in pancreatic CSCs. Here, we examined the efficacy of combining NVP-LDE-225 (PI3K/mTOR inhibitor) and NVP-BEZ-235 (Smoothened inhibitor) on pancreatic CSCs characteristics, microRNA regulatory network, and tumor growth. NVP-LDE-225 cooperated with NVP-BEZ-235 in inhibiting pancreatic CSC’s characteristics and tumor growth in NOD/SCID IL2R null mice by acting at the level of Gli. Combination of NVP-LDE-225 and NVP-BEZ-235 inhibited self-renewal capacity of CSCs by suppressing the expression of pluripotency maintaining factors Nanog, Oct-4, Sox-2 and cMyc. NVP-LDE-225 cooperated with NVP-BEZ-235 to inhibit Lin28/Let7a/Kras axis in pancreatic CSCs. Furthermore, synergistic interaction of these drugs was observed on spheroid formation by pancreatic CSCs isolated from Pankras/p53 mice. The combination of these drugs also showed synergistic effects on the expression of proteins involved in cell survival and apoptosis. In addition, synergistic effects of these drugs were observed on inhibition of epithelial-to-mesenchymal transition (EMT) through modulation of cadherin, vimentin and transcription factors Snail, Slug and Zeb1. In conclusion, these data suggest that the combined inhibition of PI3K/Akt/mTOR and Shh pathways may be an effective strategy for the treatment of pancreatic cancer.

Global transcriptomic analysis of the Raffinose Utilization in Lactobacillus salivarius Ren

Project description:This study was aimed to further illustrate the expression files of REN between glucose and raffinose in MRS broth. Transcriptomic analysis combined with mutants of the key genes based on homologous recombination technology indicated that galA1 gene cluster plays an important role in raffinose metabolism. Gene rafP and galA1 are responsible for raffinose transport and α-galactoside hydrolysis, followed by galactose hydrolysis by galKTE and sucrose hydrolysis by scrB. Lactobacillus salivarius Ren expanded the carbon utilization spectrum to adapt the fluctuating carbohydrate sources in the environment and shifted its carbohydrate metabolism to mixed-acid fermentation and then generated extra energy to bacterial growth when exposed to raffinose.

Thioguanine suppresses growth in triple-negative breast cancer by inhibiting PI3K-AKT pathway and inducing apoptosis

Project description:Triple-negative breast cancer (TNBC) is difficult to treat due to the lack of biological targets and poor sensitivity to conventional therapies. Chemotherapy is the main treatment in the clinic, but there is still no effective screening strategy for chemotherapy drugs. Several studies have attempted to find the pathogenesis through sequencing, but the integration of transcriptome maps of various tumors for drug discovery has been slow. Drug repurposing has attracted increasing attention in recent years. We first found there were common features between leukemia and TNBC. Therefore, we chose a classic leukemia drug thioguanine (6-TG) as a candidate drug. We utilized RNA-seq and DNA methylation arrays to evaluate its role in MDA-MB-231 cells. Our results demonstrated that 6-TG inhibited cell proliferation by suppressing PI3K-AKT pathway via downregulating the DNA methylation level of PTEN. Moreover, apoptosis was induced via the activation of PI3K-AKT downstream molecular TSC1 and the downregulation of methylation levels of DAXX, TNF, FADD and CASP8 etc., these genes involved in apoptosis pathways. 6-TG presents anti-tumor effects in vitro and vivo by regulating the DNA methylation levels of PI3K-AKT pathway and apoptosis pathway. Meanwhile, we proved transcriptome-based drug screening has potential implications for breast cancer therapy and drug selection.

Kanglaite reverses multidrug resistance of HCC by inducing apoptosis and cell cycle arrest via PI3K/AKT pathway.

Project description:BackgroundMultidrug resistance (MDR) frequently contributes to the failure of chemotherapeutic treatments in patients diagnosed with hepatocellular carcinoma (HCC). Revealing the molecular mechanism of MDR is indispensable for the development of effective chemotherapeutic drugs.PurposeDue to the low-toxicity modulators to inhibit MDR, we considered that Kanglaite (KLT) is a potential agent for reversing MDR in HCC.Materials and methodsBEL-7402/5-fluorouracil (5-FU) and HepG2/adriamycin (ADM) were analyzed for cell viability, colony formation assay, cell scratch assay, and cell cycle analysis and apoptosis assay by flow cytometry. The expression of PARP, caspase-3, Bax, Bcl-2, CDC25C, Cyclin B1 and phosphorylation of PTEN, PI3K, and AKT in HepG2/ADM cells were detected by western blotting.ResultsThe proliferation of drug-resistant cell lines BEL-7402/5-FU and HepG2/ADM pretreated with KLT was significantly inhibited when compared with drug alone. KLT could increase the accumulation of ADM in HepG2/ADM cells. In this study, we found that KLT treatment notably reduced cell viability, induced apoptosis and cell cycle arrest in human HepG2/ADM and BEL-7402/5-FU cells, and effectively reversed the MDR by p-glycoprotein (P-gp) inhibition. Moreover, KLT decreased the phosphorylation of AKT and PI3K in KLT-treated HepG2/ADM cells. These data together implied that KLT might reverse drug resistance in HCC by blocking the PI3K/AKT signaling.ConclusionWe demonstrated that KLT reversed MDR of human HCC by inducing apoptosis and cell cycle arrest via the PI3K/AKT signaling pathway.

Sturgeon chondroitin sulfates inhibit the proliferation of colorectal cancer cells by inducing cell cycle arrest and apoptosis

Project description:Cell proliferation assay and flow cytometric analysis were used to examine the effects of SCS treatment on viability and apoptosis of colon cancer cell HT-29 cells and normal colonic epithelial cell NCM460 cells. Transcriptomic and proteomic studies were used to identify the main targets of SCS. SCS showed little effect on the gene expression profile of NCM460 cells whereas188 genes and 10 proteins were differentially regulated in HT-29 cells after SCS treatment. Enrichment analysis of those genes / proteins showed that majority of them are involved in DNA replication, cell cycle progression, and apoptosis.

Regulation of the raffinose and melezitose utilization operons of B. breve UCC2003

Project description:Members of the genus Bifidobacterium are Gram-positive bacteria which are commonly found in the gastrointestinal tract (GIT) of mammals, including humans. Growth of bifidobacteria has been shown to be selectively stimulated by various carbohydrates found in the human diet. To extend our understanding of the regulation of bifidobacterial carbohydrate utilization systems, we investigated the regulation of two carbohydrate utilisation clusters dedicated to the metabolism of raffinose type sugars and melezitose. Transcriptomic and functional genomic approaches clearly identified that the raffinose utilisation system is positively regulated by the activator RafR, while the melezitose utilisation system is negatively regulated by lacI type transcriptional regulators. A B. breve UCC2003-rafR insertion mutant was incapable of utilising raffinose containing sugars or melibiose as a sole carbohydrate source, while the UCC2003-lacI1 and UCC2003-lacI2 insertion mutants retained their ability to utilise melezitose as a sole carbohydrate source. In silico analysis and DNA/protein interaction studies revealed a novel conserved 22 bp palindromic sequence as the RafR binding operator sequence in the rafB promoter region. Within the melezitose utilisation cluster a 20bp palindromic sequence for the melA promoter region and a 24bp palindromic sequence for the Bbr_1863 promoter region

microRNA-29b prevents liver fibrosis by attenuating hepatic stellate cell activation and inducing apoptosis through targeting PI3K/AKT pathway.

Project description:microRNA-29b (miR-29b) is known to be associated with TGF-β-mediated fibrosis, but the mechanistic action of miR-29b in liver fibrosis remains unclear and is warranted for investigation. We found that miR-29b was significantly downregulated in human and mice fibrotic liver tissues and in primary activated HSCs. miR-29b downregulation was directly mediated by Smad3 through binding to the promoter of miR-29b in hepatic stellate cell (HSC) line LX1, whilst miR-29b could in turn suppress Smad3 expression. miR-29b transduction in the liver of mice prevented CCl4 induced-fibrogenesis, concomitant with decreased expression of α-SMA, collagen I and TIMP-1. Ectopic expression of miR-29b in activated HSCs (LX-1, HSC-T6) inhibited cell viability and colony formation, and caused cell cycle arrest in G1 phase by downregulating cyclin D1 and p21cip1. Further, miR-29b induced apoptosis in HSCs mediated by caspase-9 and PARP. miR-29b inhibited its downstream effectors of PIK3R1 and AKT3 through direct targeting their 3'UTR regions. Moreover, knockdown of PIK3R1 or AKT3 suppressed α-SMA and collagen I and induced apoptosis in both HSCs and in mice. In conclusion, miR-29b prevents liver fibrogenesis by inhibiting HSC activation and inducing HSC apoptosis through inhibiting PI3K/AKT pathway. These results provide novel mechanistic insights for the anti-fibrotic effect of miR-29b.
