Discovery of Dual targeting PEGylated BG-P1600-TAT to Norepinephrin Transporter (NET) and Thyrointegrin αvβ3 in the Treatment of Neuroblastoma cancer cellline

Project description:Molecular mechanisms of anti-cancer activities of BG-P1600-TAT were explored employing genome-wide expression profiling experiments. Human neuroblastoma cell line SK-N-FI and primary cells SKNAS were treated with 30µM of the BG-P1600-TAT for 48 hours, harvested, and total RNA was immediately isolated from three biological replicates of control (vehicle-treated) and BG-P1600-TAT-treated cells. Gene expression profiling experiments identified 14-gene BG-P1600-TAT molecular interference signature captured most biologically important significantly enriched records reflecting the putative molecular mechanisms of anti-cancer activities of the BG-P1600-TAT. In BG-P1600-TAT treated SK-N-FI cells, 753 differentially expressed genes (DEGs) were identified compared to control vehicle-treated cells. Among 753 DEGs, 427 genes were down-regulated and 326 genes were up-regulated. In SKNAS cells, BG-P1600-TAT showed a significant effects on signal transduction pathways activated during cellular responses to IL-1alpha, TNF-alpha, EGF, TGF, PDGF, and AR. Further BG-P1600-TAT also showed a significant effect on multiprotein complexes of potential biological and therapeutic significance, including several complexes engaged during apoptosis (BCL-2 family protein complex; Survivin complex; BAX complex; Caspase complex), angiogenesis (VEGF-A complex; Thrombospondin complex), and cell adhesion (Galectin complex; Integrin alpha/beta complexes).

Project description:To explore molecular mechanisms of anti-cancer activities of BG-P400-TAT, genome-wide expression profiling experiments were carried out . Human neuroblastoma SKNAS cells were treated with 30µM of the BG-P400-TAT for 48 hours, harvested, and immediately processed for RNA isolation from three biological replicates of control and drug-treated cells. BG-P400-TAT targets among intracellular multiprotein complexes NF-kB complex, Survivin complex, Bcl-2 complex, and VEGF-A complex and integrated with signal transduction pathways of EGF, FGF1, AR, estradiol, TNF, and IL-1

ANTICANCER AGENT P-bi-TAT LINKS THE THYROID HORMONE RECEPTOR ON INTEGRIN αvβ3 TO CANCER CELL METABOLISM/ATP GENERATION

Project description:Microarray analysis was carried out on human GBM cells exposed to P-bi-TAT (10-6 M tetrac equivalent) for 24 h. P-bi-TAT significantly downregulated electron transport chain genes ATP5A1 (ATP synthase A1), ATP51, ATP5G2, COX6B1 (cytochrome c oxidase subunit 6B1), NDUFA8 (NADH dehydrogenase [ubiquinone] FA8), NDUFV2 and other NDUF genes, SLC25A6 (solute carrier group 2), UCP2 ([mitochondrial] uncoupling protein 2) and COX5A. The NDUF and ATP genes are also relevant to control of oxidative phosphorylation and transcription. Six additional NDUF genes linked to oxidative phosphorylation were affected. Conclusions. P-bi-TAT caused downregulation of expression of a panel of genes involved in electron transport, oxidative phosphorylation, and cytoplasmic ribosomal protein generation in GBM cells. A key component of the anticancer activity of P-bi-TAT relates to disordering of ATP generation mechanisms in tumor cells.

Significant differential expression genes from HUVECs induced by bg-CAT

Project description:In vertebrates, non-lens bg-crystallins are widely expressed in various tissues, but their functions are unknown. The molecular mechanisms of trefoil factors, initiators of mucosal healing and being greatly involved in tumorigenesis, have remained elusive.A naturally existing 72-kDa complex of non-lens bg-crystallin (a-subunit) and trefoil factor (b-subunit), named bg-CAT, was identified from frog Bombina maxima skin secretions. Its a-subunit and b-subunit (containing three trefoil factor domains), with a non-covalently linked form of ab2, show significant sequence homology to ep37 proteins, a group of non-lens bg-crystallins identified in newt Cynops pyrrhogaster and mammalian trefoil factors, respectively. The bg-CAT showed multiple cellular effects on human umbilical vein endothelial cells. Low dosages of bg-CAT (25-50 pM) were able to stimulate cell migration and wound healing. At high concentrations, it induced cell detachment (EC50 10 nM) and apoptosis. The bg-CAT was rapidly endocytosed via intracellular vacuole formation. Under confocal microscope, some of the vacuoles were translocated to nucleus and partially fused with nuclear membrane. However, what exactly target of bg-CAT act on HUVECs nuclear is still unknown. Primary cultured HUVECs treated with bg-CAT (25 nM, 2 h) were selected for RNA extraction and hybridization on Affymetrix microarrays. We sought to obtain the genome wide level of significant differential gene expression induced by bg-CAT on HUVECs in order to get clues about bg-CAT action mechanisms. These findings illustrate novel cellular functions of non-lens bg-cyrstallins and action mechanism via association with trefoil factors, serving as clues for investigating the possible occurrence of similar molecules and action mechanisms in mammals.

Integrin αvβ3 acting as membrane receptor for thyroid hormones mediates angiogenesis in malignant T cells

Project description:We have found that thyroid hormones (THs), acting as soluble integrin αvβ3 ligands, activate growth-related signaling pathways in T-cell lymphomas (TCL). Specifically, TH-activated αvβ3 integrin signaling promotes TCL proliferation and angiogenesis, in part, via the up-regulation of VEGF. CUTLL1 cells were treated with T3- and T4-bound agarose or agarose alone for 24hrs. Total RNA was harvested from cells and used for expression profiling via RNA-seq.
