It is becoming increasingly understood that tumor cells may have different
mutations and dependencies on diverse intracellular signaling cascades for
survival or metastatic potential. Overexpression of oncogenes, inactivation of
tumor suppressor genes, genetic/epigenetic mutations, genomic instability, and
loss of apoptotic cell death are some of the mechanisms that have been widely
investigated in molecular oncology. We partition this multicomponent review into
the most recent evidence on the anticancer activity of fungal substances obtained
from in vitro and xenografted models, and these fungal substances modulate
expression of oncogenic and tumor suppressor miRNAs. There are some outstanding
questions regarding fungus-derived chemical-induced modulation of intracellular
signaling networks in different cancer cell lines and preclinical models. Certain
hints have emerged, emphasizing mechanisms via which apoptosis can be restored in
TRAIL-resistant cancer cells. Reconceptualization of the knowledge obtained from
these emerging areas of research will enable us to potentially identify natural
agents with notable anticancer activity and minimal off-target effects.
Integration of experimentally verified evidence obtained from cancer cell line
gene expression with large-scale functional screening results and pharmacological
sensitivity data will be helpful in identification of therapeutics with
substantial efficacy. New tools and technologies will further deepen our
understanding of the signaling networks that underlie the development of cancer,
metastasis, and resistance to different therapeutics at both a personal and
systems-wide level.
