The tumor suppressor SCRIB is a negative modulator of the Wnt/-catenin signaling (part 1)

ABSTRACT: Epithelial tissues are highly organized structures that rely on cell polarity pathways driven by membrane receptors and scaffolding proteins. SCRIBBLE is a cytoplasmic scaffold present at cell-cell junctions in polarized cells that contains LRR and PDZ domains as its paralogue LANO, a member of the LAP protein family. The family is composed of DENSIN-180, ERBIN, SCRIB and LRRC1. Based on phylogenic tree, LAP proteins can be split in two branches with the first branch is made up with SCRIB and LRCC1 and the second one of ERBIN and DENSIN-180. The current interactome of SCRIB and LRRC1 consists of 67 and 30 protein interaction partners respectively with only 9 (10%) common partners (BioGRID, version 3.5). Our study uncovers the proteome associated to SCRIB and LRRC1 and described for the first time protein associated to each paralogue.

SCRIB is a scaffold protein containing leucine-rich repeats (LRR) and PSD-95/Dlg-A/ZO-1 domains (PDZ) that localizes at the basolateral membranes of polarized epithelial cells. Deregulation of its expression or localization leads to epithelial defects and tumorigenesis in part as a consequence of its repressive role on several signaling pathways including AKT, ERK, and HIPPO. In the present work, a proteomic approach is used to characterize the protein complexes associated to SCRIB and its paral ...[more]

Project description:C/EBPβ plays a major role in numerous biological processes but unfortunately its precise role is not still clear and conflicting studies showed that this transcription factor could have contradictory functions. These latter arise from the complexity of mechanisms regulating C/EBPβ activity. Indeed, C/EBPβ encodes an intronless gene that generates a single mRNA that is alternatively translated into two major isoforms of 35kDa (liver-enriched activator protein: LAP) and 20kDa (liver-enriched inhibitory protein: LIP). LAP is the active isoform of this transcription factor whereas LIP, a truncated isoform negatively regulate C/EBPβ-LAP-mediated gene expression. The main goal of our research was to understand how LAP and LIP isoforms governe C/EBPβ cellular functions with the identification of new genes and pathways regulated by these isoforms in the human Hep3B hepatoma cell line. For this purpose an original in vitro system characterized by a target genes induction with the activatory C/EBPß isoform LAP and a target genes repression with the inhibitory C/EBPß isoform (LIP) was used to identify the genuine C/EBPβ molecular signature. Using a cDNA microarray which provides a complete coverage of the liver transcriptome, we identified 676 genes inversely regulated by LAP and LIP. These selected genes are involved in many biological processes as the hepatic metabolism (cholesterol), detoxification, induction of apoptosis and negative regulation of the cell proliferation. According to the involvement of C/EBPβ in hepatic carcinogenesis we focused on cell cycle regulation and apoptosis. Through functional studies, we proved for the first time that LIP plays in favor of the survival of the Hep3B cells whereas LAP makes the cells more sensitive to staurosporine-induced cell death. Moreover, a lot of studies demonstrated that the anti-proliferative action of C/EBPβ mainly depends on RB protein. By studying the rate of Hep3B cells proliferation which overexpress LAP, we brought to the fore that this isoform would be able to induce a repression of the Hep3B cells line proliferation - a RB- and p53- negative cell line. Thus, LAP seems able to induce the repression of proliferation by a different metabolic way from the RB one. Keywords: comparison of cells expressing LAP or LIP RNA were extracted from 5 Hep3BLAPexpressing LAP, 5 Hep3BLAP control without expression of LAP, 5 Hep3BLIP expressing LIP and 5 Hep3BLIP control without epression of LIP. Each sample was hybridized once in 5 different nylon membranes.

Project description:β-lapachone (b-lap) is an anticancer agent that selectively induces cell death in human cancer cells. A mechanism for b-lap cytotoxicity was shown to be mediated by the NQO1 NAD(P)H dehydrogenase and radical oxygen species (ROS) generation in several tumour cells. To further characterise the molecular effects of b-lap action, we compared the gene expression profile of yeast cells treated or not with b-lap using cDNA microarrays. Genes involved in tolerance to oxidative stress were enriched in the set of differentially expressed genes. Accordingly, b-lap treatment generated reactive oxygen species (ROS), which were efficiently blocked by dicoumarol, and inhibitor of NADH dehydrogenases (NADH-DH). In addition, a mutant defective in the mitocondrial NADH dehydrogenase Nde2p was found to be resistant to b-lap treatment, thus resembling tumour cell responses to b-lap exposure. However, b-lap treatment elicited similar ROS production in WT and nde2 cells, and dicoumarol did not affect cell viability in b-lap treated yeasts. Most interestingly, DNA damage responses triggered by b-lap were abolished in the nde2 mutant. Furthermore, the nde2 mutant was sensitive to DNA damaging agents other than b-lap. These data indicated that ROS production did not mediate b-lap cytotoxicity and highlighted a role of Nde2p in DNA damage checkpoints. Amino acid biosynthesis genes were also differentially expressed in b-lap treated cells, suggesting that b-lap exposure somehow triggered the General Control of Nutrients (GCN) pathway. Supporting this, b-lap treatment increased phosphorylation of eIF2 alpha in a Gcn2p-dependent manner. eIF2alpha phosphorylation required Gcn1p and Gcn20p and surprisingly Nde2p. Gcn2p was also shown to be required for the G1 checkpoint triggered by b-lap and for cell survival. Remarkably, b-lap treatment also increased phosphorylation of eIF2 alpha in breast tumour cells, which was partially dependent on the Nde2p orthologue AMID. These findings i) suggest that Gcn2p and Nde2p are key determinants of b-lap toxicity in yeast and human cells, ii) uncover a new functional connection between Nde2p, Gcn2p and DNA damage checkpoints conserved throughout evolution and iii) suggest that pharmacological modulation of Gcn2p could provide an effective strategy for antitumour drug discovery.

Project description:Current human reproductive risk assessment methods rely on semen and serum hormone analyses, which are not easily comparable to the histopathological endpoints and mating studies used in animal testing. Because of these limitations, there is a need to develop universal evaluations that reliably reflect male reproductive function. We hypothesized that toxicant-induced testicular injury can be detected in sperm using mRNA transcripts as indicators of insult. To test this, we exposed adult male Fischer 344 rats to low doses of model testicular toxicants and classically characterized the testicular injury while simultaneously evaluating sperm mRNA transcripts from the same animals. Overall, this study aimed to: 1) identify sperm transcripts altered after exposure to the model testicular toxicant, 2,5-hexanedione (HD) using microarrays; 2) expand on the HD-induced transcript changes in a comprehensive time course experiment using qRT-PCR arrays; and 3) test these injury indicators after exposure to another model testicular toxicant, carbendazim (CBZ). Microarray analysis of HD-treated adult Fischer 344 rats identified 128 altered sperm mRNA transcripts when compared to control using linear models of microarray analysis (q < 0.05). All transcript alterations disappeared after 3 months of post-exposure recovery. In the time course experiment, time-dependent alterations were observed for 12 candidate transcripts selected from the microarray data based upon fold change and biological relevance, and 8 of these transcripts remained significantly altered after the 3-month recovery period (p < 0.05). In the last experiment, 8 candidate transcripts changed after exposure to CBZ (p < 0.05). The two testicular toxicants produced distinct molecular signatures with only 4 overlapping transcripts between them, each occurring in opposite directions. Overall, these results suggest that sperm mRNA transcripts are indicators of low dose toxicant-induced testicular injury in the rat. Rats were exposed to sub-chronic low doses of the Sertoli cell toxicant 2,5-hexanedione (HD) or water (control for HD) for 3 months. Some rats in each group underwent 3 months of post-exposure recovery.
