RESUMEN
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.

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.
