Abstract:
Nitric oxide, carbon monoxide, and hydrogen sulfide, once recognized primarily for their toxicity or vasoactive properties, have emerged as multifaceted signaling molecules in cancer biology. This review provides an update on current findings on how gasotransmitters support cancer processes. Gasotransmitters act through activation of soluble guanylate cyclase, redox-dependent post-translational modifications such as S-nitrosylation and persulfidation, mitochondrial metabolic regulation, calcium signaling, and crosstalk with pathways, and telomerase-related networks. In addition, the same gasotransmitter has either pro-tumorigenic or anti-tumorigenic effects. Overall, this review highlights gasotransmitters as diverse regulators of cancer progression and indicates the potential of precisely modulating gasotransmitter signaling in targeted cancer therapy.

Cancer Therapies
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...

Interactions Between Signaling Pathways
Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...
Metastasis
Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...
