Abstract
There is much evidence that the vertebrate lung originated from a progenitor structure which was present in bony fish. However, critical basic elements for the evolution of breathing in tetrapods, such as the central rhythm generator sensitive to CO2/pH and the pulmonary surfactant, were present in the lungless primitive vertebrate. This suggests that the evolution of air breathing in all vertebrates may have evolved through exaptations. It appears that the capability for proliferation of alveolar type 1 (AT1) cells is the "critical factor" which rendered possible the most radical subsequent innovation-the possibility of air breathing. "Epithelial remodeling," which consists in proliferation of alveolar cells-the structural basis for gas diffusion-observed in the alimentary tract of the gut-breathing fishes (GBF) has great potential for application in biomedical research. Such a process probably led to the gradual evolutionary development of lungs in terrestrial vertebrates. Research on the cellular and molecular mechanisms controlling proliferation of squamous epithelial cells in the GBF should contribute to explaining the regeneration-associated phenomena that occur in mammal lungs, and especially to the understanding of signal pathways which govern the process.

Elevating EGFR-MAPK program by a nonconventional Cdc42 enhances intestinal epithelial survival and regeneration. JCI Insight 2020; 5:135923. [PMID: 32686657 PMCID: PMC7455142 DOI: 10.1172/jci.insight.135923] [Citation(s) in RCA: 18] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/20/2019] [Accepted: 07/09/2020] [Indexed: 01/05/2023] Open
Abstract
The regulatory mechanisms enabling the intestinal epithelium to maintain a high degree of regenerative capacity during mucosal injury remain unclear. Ex vivo survival and clonogenicity of intestinal stem cells (ISCs) strictly required growth response mediated by cell division control 42 (Cdc42) and Cdc42-deficient enteroids to undergo rapid apoptosis. Mechanistically, Cdc42 engaging with EGFR was required for EGF-stimulated, receptor-mediated endocytosis and sufficient to promote MAPK signaling. Proteomics and kinase analysis revealed that a physiologically, but nonconventionally, spliced Cdc42 variant 2 (V2) exhibited stronger MAPK-activating capability. Human CDC42-V2 is transcriptionally elevated in some colon tumor tissues. Accordingly, mice engineered to overexpress Cdc42-V2 in intestinal epithelium showed elevated MAPK signaling, enhanced regeneration, and reduced mucosal damage in response to irradiation. Overproducing Cdc42-V2 specifically in mouse ISCs enhanced intestinal regeneration following injury. Thus, the intrinsic Cdc42-MAPK program is required for intestinal epithelial regeneration, and elevating this signaling cascade is capable of initiating protection from genotoxic injury.

Chemoreceptors as a key to understanding carcinogenesis process. Semin Cancer Biol 2019; 60:362-364. [PMID: 31622661 DOI: 10.1016/j.semcancer.2019.10.003] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/03/2019] [Revised: 10/04/2019] [Accepted: 10/04/2019] [Indexed: 11/22/2022]
Abstract
The tissue organization field theory (TOFT) presented completely new, different from the previous one, perspective of research on neoplasm processes. It implicates that secretory neuroepithelial-like cells (NECs), putative chemoreceptors are probably responsible for the control of squamous epithelial cells proliferation in the digestive tract during hypoxia in gut breathing fish (GBF). On the other hand, chemoreceptors dysfunction can lead to uncontrolled proliferation and risk of cancer development in mammals, including humans. The studies on NECs like cells (signal capturing and transduction) may be crucial for understanding the processes of controlling the proliferation of squamous epithelial cells in the digestive tract of GBF fish during hypoxia states. This knowledge can contribute to the explanation of cancer processes.

From epithelial remodelling to carcinogenesis. PROGRESS IN BIOPHYSICS AND MOLECULAR BIOLOGY 2019; 150:203-205. [PMID: 31381892 DOI: 10.1016/j.pbiomolbio.2019.08.001] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/16/2019] [Revised: 07/23/2019] [Accepted: 08/01/2019] [Indexed: 02/01/2023]
Abstract
The novel cancer theory named 'the tissue organization field theory' (TOFT) suggests that carcinogenesis is a process analogous to embryonic development, whereby organs are formed through interactions among different cell types. The suggested 'morphological remodelling' of the epithelium under hypoxia in gut breathing fish (GBF) has many common features with carcinogenesis. It appears that research into the relationship among epidermal growth factor receptor (EGFR), hypoxia inducible factor (HIF) as well as hypoxia and normoxia states in GBF fishes can be crucial in learning about the steering mechanisms of squamous epithelium proliferation, leading to a better understanding of carcinogenesis.

Differential expression of epidermal growth factor receptor (EGFR) in stomach and diverticulum of Otocinclus affinis (Steindachner, 1877) as a potential element of the epithelium remodeling mechanism. Acta Histochem 2019; 121:151-155. [PMID: 30528348 DOI: 10.1016/j.acthis.2018.11.008] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/05/2018] [Revised: 11/29/2018] [Accepted: 11/29/2018] [Indexed: 01/08/2023]
Abstract
It is suggested that due to the several stomach modifications, Otocinculus affinis (dwarf sucking catfish) possess the ability to breathe air during hypoxia, however, the exact mechanism remains unknown. The aim of this study was detailed analysis of the expression of EGFR in the stomach and diverticulum of the O. affinis at the mRNA and protein levels together with the immunohistochemical localization of EGFR in these organs. The intensity of band fluorescence corresponding to the EGFR gene expression level is significantly higher in the stomach than in the diverticulum. Further, quantitative analysis of EGFR protein abundance also revealed its higher synthesis in the stomach than in the diverticulum and the immunohistochemistry method confirmed these results. As regional localization of respiratory function in gut air-breathing fishes seems to be connected with "morphological remodeling" of the epithelium of their gut, the present research demonstrated the potential efficiency of the O. affinis stomach as a respiratory organ. Having the potential possibility to create an air-blood barrier in the gastrointestinal tract allowing gas diffusion and respiration in hypoxic states seems to be very beneficial for these fish. It seems that facultative gut air breathing fish species are a relevant vertebrate model for high throughput screening, vascular biology and evolution.

Abstract
Bronze corydoras (Corydoras aeneus) is a small diurnal activity fish from South America. Under hypoxia conditions, it uses the posterior part of the intestine as an accessory respiratory organ. The present PCR studies demonstrated higher expression of HIF-1α (hypoxia-inducible factor) gene in the respiratory than that in digestive part of bronze corydoras intestine. Further, immunolocalization studies using antibodies specific to HIF-1α and transmission electron microscopy (TEM) revealed the presence of HIF-1α epitopes in the intestine of Corydoras aeneus. In the respiratory intestine, the numerous clusters of gold particles visualizing HIF-1α antibody were observed within fibroblasts, whereas in the digestive tract of this species, single gold grains in the epithelial cells were noted. On the other hand, the presence of HIF-1α and the cytoplasmic domain of the epidermal growth factor receptor (EGFR) in the respiratory intestine of bronze corydoras assumes their interactions in the system where these factors appeared for the first time. The non-obligatory air-breathing fishes using their digestive tract as an accessory respiratory organ during hypoxia conditions are very interesting for the studies of the processes that control HIF-1α expression and squamous cell proliferation.
