Abstract:
Perturbations in molecular signaling pathways are a result
of genetic or epigenetic alterations, which may lead to
malignant transformation of cells. Despite cellular robustness,
specific genetic or epigenetic changes of any gene can trigger
a cascade of failures, which result in the malfunctioning of
cell signaling pathways and lead to cancer phenotypes. The
extent of cellular robustness has a link with the architecture
of the network such as feedback and feedforward loops.
Perturbation in components within feedback loops causes a
transition from a regulated to a persistently activated state
and results in uncontrolled cell growth. This work represents
the mathematical and quantitative modeling of ERK, PI3K/Akt,
and Wnt/?-catenin signaling crosstalk to show the dynamics of
signaling responses during genetic and epigenetic changes in
cancer. ERK, PI3K/Akt, and Wnt/?-catenin signaling crosstalk
networks include both intra and inter-pathway feedback loops
which function in a controlled fashion in a healthy cell. Our
results show that cancerous perturbations of components such as
EGFR, Ras, B-Raf, PTEN, and components of the destruction
complex cause extreme fragility in the network and
constitutively activate inter-pathway positive feedback loops.
We observed that the aberrant signaling response due to the
failure of specific network components is transmitted
throughout the network via crosstalk, generating an additive
effect on cancer growth and proliferation.

Project description:Metastatic breast cancer is an extremely complex disease with limited treatment options due to the lack of information about the major characteristics of metastatic disease. There is an urgent need, therefore, to understand the changes in cellular complexity and dynamics that occur during metastatic progression. In the current study, we analyzed the cellular and molecular differences between primary tumors and paired lung metastases using a syngeneic p53-null mammary tumor model of basal-like breast cancer. Distinct subpopulations driven by the Wnt- and/or STAT3 signaling pathways were detected in vivo using a lentiviral Wnt- and STAT3 signaling reporter system. A significant increase in the overlapping populations driven by both the Wnt- and STAT3 signaling pathways was observed in the lung metastases as compared to the primary tumors. Furthermore, STAT3 signaling activity was markedly enhanced in the metastatic lesions relative to the primary tumors with minimal changes observed in Wnt reporter activity. An analysis of the unique molecular features of the lung metastases revealed a significant association with immune response signatures. Specifically, Foxp3 gene expression was markedly increased and elevated levels of Foxp3+ Treg cells were detected in close proximity to lung metastases. Collectively, these studies illustrate the importance of analyzing intratumoral heterogeneity, changes in population dynamics and the immune microenvironment during metastatic progression.

Project description:Malignant melanoma is characterized by frequent metastasis, however specific changes that regulate this process have not been clearly delineated. Although it is well known that Wnt signaling is frequently dysregulated in melanoma, the functional implications of this observation are unclear. By modulating beta-catenin levels in a mouse model of melanoma that is based on melanocyte-specific Pten loss and BrafV600E mutation, we demonstrate that beta-catenin is a central mediator of melanoma metastasis to lymph node and lung. In addition to altering metastasis, beta-catenin levels control tumor differentiation and regulate both MAPK/Erk and PI3K/Akt signaling. Highly metastatic tumors with beta-catenin stabilization are very similar to a subset of human melanomas; together these findings establish Wnt signaling as a metastasis regulator in melanoma.
