Abstract
Growing evidence exposes translation and its translational machinery as key players in establishing and maintaining physiological and pathological biological processes. Examining translation may not only provide new biological insight but also identify novel innovative therapeutic targets in several fields of biology, including that of epithelial-to-mesenchymal transition (EMT). EMT is currently considered as a dynamic and reversible transdifferentiation process sustaining the transition from an epithelial to mesenchymal phenotype, known to be mainly driven by transcriptional reprogramming. However, it seems that the characterization of EMT plasticity is challenging, relying exclusively on transcriptomic and epigenetic approaches. Indeed, heterogeneity in EMT programs was reported to depend on the biological context. Here, by reviewing the involvement of translational control, translational machinery and ribosome biogenesis characterizing the different types of EMT, from embryonic and adult physiological to pathological contexts, we discuss the added value of integrating translational control and its machinery to depict the heterogeneity and dynamics of EMT programs.

Modulating effects of acyl-CoA synthetase 5-derived mitochondrial Wnt2B palmitoylation on intestinal Wnt activity. World J Gastroenterol 2014; 20:14855-14864. [PMID: 25356045 PMCID: PMC4209548 DOI: 10.3748/wjg.v20.i40.14855] [Citation(s) in RCA: 18] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/20/2014] [Revised: 05/10/2014] [Accepted: 06/23/2014] [Indexed: 02/06/2023] Open
Abstract
AIM: To investigate the role of acyl-CoA synthetase 5 (ACSL5) activity in Wnt signaling in intestinal surface epithelia.
METHODS: Several cell lines were used to investigate the ACSL5-dependent expression and synthesis of Wnt2B, a mitochondrially expressed protein of the Wnt signaling family. Wnt activity was functionally assessed with a luciferase reporter assay. ACSL5-related biochemical Wnt2B modifications were investigated with a modified acyl-exchange assay. The findings from the cell culture models were verified using an Apcmin/+ mouse model as well as normal and neoplastic diseased human intestinal tissues.
RESULTS: In the presence of ACSL5, Wnt2B was unable to translocate into the nucleus and was enriched in mitochondria, which was paralleled by a significant decrease in Wnt activity. ACSL5-dependent S-palmitoylation of Wnt2B was identified as a molecular reason for mitochondrial Wnt2B accumulation. In cell culture systems, a strong relation of ACSL5 expression, Wnt2B palmitoylation, and degree of malignancy were found. Using normal mucosa, the association of ACSL5 and Wnt2B was seen, but in intestinal neoplasias the mechanism was only rudimentarily observed.
CONCLUSION: ACSL5 mediates antiproliferative activities via Wnt2B palmitoylation with diminished Wnt activity. The molecular pathway is probably relevant for intestinal homeostasis, overwhelmed by other pathways in carcinogenesis.

Abstract
Polycomb proteins form multiprotein complexes that repress target genes by chromatin remodeling. In this work, we report that the SUZ12 polycomb gene is over-expressed in bone marrow samples of patients at the blastic phase of chronic myeloid leukemia. We also found a direct interaction between polycomb group genes and the WNT signaling pathway in chronic myeloid leukemia transformation. Electrophoretic mobility shift assay (EMSA), Chromatin immunoprecipitation assay (ChIP), and mass spectrometry assays identified noncanonical WNT pathway members, such as WNT5A and WNT11, bound to the SUZ12 promoter. Immunohistochemistry and immunofluorescence with WNT5A and WNT11 antibodies confirmed nuclear localization. Knockdown of WNTs 1, 5A, and 11 with RNAi approaches showed that WNT members are capable of activating SUZ12 transcription with varying promoter affinities. Finally, we suggest that SUZ12 is blocking cellular differentiation, as SUZ12 knockdown release differentiation programs in chronic myeloid blastic phase (CML-BP) transformed cell line.

Abstract
Some extracellular-signaling peptides also at times function within the intracellular space. We have termed these peptides intracrines and have argued that intracrine function is associated with a wide variety of peptides/proteins including hormones, growth factors, cytokines, enzymes, and DNA-binding proteins among others. Here we consider the possibility that intracrines participate in the related phenomena of senescence, apoptosis, and stem cell regulation of tissue biology. Based on this analysis, we also suggest that the concept of intracrine action be expanded to include possible regulatory peptide transfer via exosomes/microvesicles and possibly by nanotubes. Moreover, the process of microvesicular and nanotube transfer of peptides and other biologically relevant molecules, which we inclusively term laterality, is explored. These notions have potentially important therapeutic implications, including implications for the therapy of cardiovascular disease.
