Project description:We utilize MeDIP-seq, hMeDIP-seq and RNA-seq technologies to explore the epigenetic alterations in HCC after MenSC therapy. We provide distinct epigenetic landscapes of HCC cells mediated by MenSCs and demonstrate that MenSCs exert anticancer functions by regulating 5-hmC and 5-mC abundance in enhancer and promoter regions of oncogenic pathways. Deactivation of PI3K/AKT and RAF/ERK signaling attenuated the inhibition of FOXO3 and promoted downstream apoptosis. Moreover, an increase in PTEN further strengthened the suppressive effect on PI3K/AKT. Additionally, inactivation of phosphorylated ERK repressed c-myc-mediated EMT. Taken together, our results provided important epigenetic evidence for clarifying the mechanism of crosstalk between cancer and MSCs in the microenvironment and screening effective epigenetic targets for future therapy strategies based on modified MSCs.

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.
