Amor-Guéret M. Loss of cytidine deaminase expression as a potential attempt to counteract the process of carcinogenesis by reducing basal PARP-1 activity and increasing tau levels. Biochim Biophys Acta Mol Basis Dis 2024; 1870:167213. [PMID: 38714266 DOI: 10.1016/j.bbadis.2024.167213] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/23/2023] [Revised: 04/01/2024] [Accepted: 05/01/2024] [Indexed: 05/09/2024]
Abstract
Cytidine deaminase (CDA) is a pyrimidine salvage pathway enzyme that catalyzes the hydrolytic deamination of free cytidine and deoxycytidine to uridine and deoxyuridine, respectively. Our team discovered that CDA deficiency is associated with several aspects of genetic instability, such as increased sister chromatid exchange and ultrafine anaphase bridge frequencies. Based on these results, we sought (1) to determine how CDA deficiency contributes to genetic instability, (2) to explore the possible relationships between CDA deficiency and carcinogenesis, and (3) to develop a new anticancer treatment targeting CDA-deficient tumors. This review summarizes our major findings indicating that CDA deficiency is associated with a genetic instability that does not confer an increased cancer risk. In light of our results and published data, I propose a novel hypothesis that loss of CDA, by reducing basal PARP-1 activity and increasing Tau levels, may reflect an attempt to prevent, slow or reverse the process of carcinogenesis.

Abstract
Multiple theories exist to explain cancer initiation, although a consensus on this is crucial for developing effective therapies. 'Somatic mutation theory' suggests that mutations in somatic cells during DNA repair initiates cancer but this concept has several attached paradoxes. Research efforts to identify quiescent cancer stem cells (CSCs) that survive therapy and result in metastasis and recurrence have remained futile. In solid cancers, CSCs are suggested to appear during epithelial-mesenchymal transition by the dedifferentiation and reprogramming of epithelial cells. Pluripotent and quiescent very small embryonic-like stem cells (VSELs) exist in multiple tissues but remain elusive owing to their small size and scarce nature. VSELs are developmentally connected to primordial germ cells, undergo rare, asymmetrical cell divisions and are responsible for the regular turnover of cells to maintain tissue homeostasis throughout life. VSELs are directly vulnerable to extrinsic endocrine insults because they express gonadal and gonadotropin hormone receptors. VSELs undergo epigenetic changes due to endocrine insults and transform into CSCs. CSCs exhibit genomic instability and develop mutations due to errors during DNA replication while undergoing excessive proliferation and clonal expansion to form spheroids. Thus tissue-resident VSELs offer a connection between extrinsic insults and variations in cancer incidence reported in various body tissues. To conclude, cancer is indeed a stem cell disease with mutations occurring as a consequence. In addition to immunotherapy, targeting mutations, and Lgr5 + organoids for developing new therapeutics, targeting CSCs (epigenetically altered VSELs) by improving their niche and epigenetic status could serve as a promising strategy to treat cancer.

Cytidine deaminase deficiency in mice enhances genetic instability but limits the number of chemically induced colon tumors. Cancer Lett 2023; 555:216030.

Abstract
Cytidine deaminase (CDA) catalyzes the deamination of cytidine (C) and deoxycytidine (dC) to uridine and deoxyuridine, respectively. We recently showed that CDA deficiency leads to genomic instability, a hallmark of cancers. We therefore investigated whether constitutive CDA inactivation conferred a predisposition to cancer development. We developed a novel mouse model of Cda deficiency by generating Cda-knockout mice. Cda+/+ and Cda-/- mice did not differ in lifetime phenotypic or behavioral characteristics, or in the frequency or type of spontaneous cancers. However, the frequency of chemically induced tumors in the colon was significantly lower in Cda-/- mice. An analysis of primary kidney cells from Cda-/- mice revealed an excess of C and dC associated with significantly higher frequencies of sister chromatid exchange and ultrafine anaphase bridges and lower Parp-1 activity than in Cda+/+ cells. Our results suggest that, despite inducing genetic instability, an absence of Cda limits the number of chemically induced tumors. These results raise questions about whether a decrease in basal Parp-1 activity can protect against inflammation-driven tumorigenesis; we discuss our findings in light of published data for the Parp-1-deficient mouse model.

Abstract
In view of unified cell bioenergetics, cell bioenergetic problems related to cell overenergization can cause excessive disturbances in current cell fate and, as a result, lead to a change of cell-fate. At the onset of the problem, cell overenergization of multicellular organisms (especially overenergization of mitochondria) is solved inter alia by activation and then stimulation of the reversible Crabtree effect by cells. Unfortunately, this apparently good solution can also lead to a much bigger problem when, despite the activation of the Crabtree effect, cell overenergization persists for a long time. In such a case, cancer transformation, along with the Warburg effect, may occur to further reduce or stop the charging of mitochondria by high-energy molecules. Understanding the phenomena of cancer transformation and cancer development has become a real challenge for humanity. To date, many models have been developed to understand cancer-related mechanisms. Nowadays, combining all these models into one coherent universal model of cancer transformation and development can be considered a new challenge. In this light, the aim of this article is to present such a potentially universal model supported by a proposed new model of cellular functionality evolution. The methods of fighting cancer resulting from unified cell bioenergetics and the two presented models are also considered.

Abstract
The role of plasticity and epigenetics in shaping cancer evolution and response to therapy has taken center stage with recent technological advances including single cell sequencing. This roadmap article is focused on state-of-the-art mathematical and experimental approaches to interrogate plasticity in cancer, and addresses the following themes and questions: is there a formal overarching framework that encompasses both non-genetic plasticity and mutation-driven somatic evolution? How do we measure and model the role of the microenvironment in influencing/controlling non-genetic plasticity? How can we experimentally study non-genetic plasticity? Which mathematical techniques are required or best suited? What are the clinical and practical applications and implications of these concepts?
