Disruption of Redox Homeostasis by Alterations in Nitric Oxide Synthase Activity and Tetrahydrobiopterin along with Melanoma Progression. Int J Mol Sci 2022; 23:5979.

Abstract
Cutaneous melanoma emerges from the malignant transformation of melanocytes and is the most aggressive type of skin cancer. The progression can occur in different stages: radial growth phase (RGP), vertical growth phase (VGP), and metastasis. Reactive oxygen species contribute to all phases of melanomagenesis through the modulation of oncogenic signaling pathways. Tetrahydrobiopterin (BH4) is an important cofactor for NOS coupling, and an uncoupled enzyme is a source of superoxide anion (O2•-) rather than nitric oxide (NO), altering the redox homeostasis and contributing to melanoma progression. In the present work, we showed that the BH4 amount varies between different cell lines corresponding to distinct stages of melanoma progression; however, they all presented higher O2•- levels and lower NO levels compared to melanocytes. Our results showed increased NOS expression in melanoma cells, contributing to NOS uncoupling. BH4 supplementation of RGP cells, and the DAHP treatment of metastatic melanoma cells reduced cell growth. Finally, Western blot analysis indicated that both treatments act on the PI3K/AKT and MAPK pathways of these melanoma cells in different ways. Disruption of cellular redox homeostasis by the altered BH4 concentration can be explored as a therapeutic strategy according to the stage of melanoma.

Multi-Compartmentalisation in the MAPK Signalling Pathway Contributes to the Emergence of Oscillatory Behaviour and to Ultrasensitivity. PLoS One 2016; 11:e0156139.

Abstract
Signal transduction through the Mitogen Activated Protein Kinase (MAPK) pathways is evolutionarily highly conserved. Many cells use these pathways to interpret changes to their environment and respond accordingly. The pathways are central to triggering diverse cellular responses such as survival, apoptosis, differentiation and proliferation. Though the interactions between the different MAPK pathways are complex, nevertheless, they maintain a high level of fidelity and specificity to the original signal. There are numerous theories explaining how fidelity and specificity arise within this complex context; spatio-temporal regulation of the pathways and feedback loops are thought to be very important. This paper presents an agent based computational model addressing multi-compartmentalisation and how this influences the dynamics of MAPK cascade activation. The model suggests that multi-compartmentalisation coupled with periodic MAPK kinase (MAPKK) activation may be critical factors for the emergence of oscillation and ultrasensitivity in the system. Finally, the model also establishes a link between the spatial arrangements of the cascade components and temporal activation mechanisms, and how both contribute to fidelity and specificity of MAPK mediated signalling.

Abstract
![]()
Studies were undertaken to determine
whether extracellular signal
regulated kinase (ERK) oscillations regulate a unique subset of genes
in human keratinocytes and subsequently whether the p38 stress response
inhibits ERK oscillations. A DNA microarray identified many genes
that were unique to ERK oscillations, and network reconstruction predicted
an important role for the mediator complex subunit 1 (MED1) node in
mediating ERK oscillation-dependent gene expression. Increased ERK-dependent
phosphorylation of MED1 was observed in oscillating cells compared
to nonoscillating counterparts as validation. Treatment of keratinocytes
with a p38 inhibitor (SB203580) increased ERK oscillation amplitudes
and MED1 and phospho-MED1 protein levels. Bromate is a probable human
carcinogen that activates p38. Bromate inhibited ERK oscillations
in human keratinocytes and JB6 cells and induced an increase in phospho-p38
and a decrease in phospho-MED1 protein levels. Treatment of normal
rat kidney cells and primary salivary gland epithelial cells with
bromate decreased phospho-MED1 levels in a reversible fashion upon
treatment with p38 inhibitors (SB202190; SB203580). Our results indicate
that oscillatory behavior in the ERK pathway alters homeostatic gene
regulation patterns and that the cellular response to perturbation
may manifest differently in oscillating vs nonoscillating cells.

Abstract
There is increasing emphasis on the use of systems biology approaches to define radiation-induced responses in cells and tissues. Such approaches frequently rely on global screening using various high throughput 'omics' platforms. Although these methods are ideal for obtaining an unbiased overview of cellular responses, they often cannot reflect the inherent heterogeneity of the system or provide detailed spatial information. Additionally, performing such studies with multiple sampling time points can be prohibitively expensive. Imaging provides a complementary method with high spatial and temporal resolution capable of following the dynamics of signaling processes. In this review, we utilize specific examples to illustrate how imaging approaches have furthered our understanding of radiation-induced cellular signaling. Particular emphasis is placed on protein colocalization, and oscillatory and transient signaling dynamics.
