The past few decades have welcomed tremendous advancements toward understanding
the functional significance of altered metabolism during tumorigenesis. However,
many conclusions drawn from studies of cancer cells in a dish (i.e., in vitro)
have been put into question as multiple lines of evidence have demonstrated that
the metabolism of cells can differ significantly from that of primary tumors (in
vivo). This realization, along with the need to identify tissue-specific
vulnerabilities of driver oncogenes, has led to an increased focus on
oncogene-dependent metabolic programming in vivo. The oncogene c-MYC (MYC) is
overexpressed in a wide variety of human cancers, and while its ability to alter
cellular metabolism is well-established, translating the metabolic requirements,
and vulnerabilities of MYC-driven cancers to the clinic has been hindered by
disparate findings from in vitro and in vivo models. This review will provide an
overview of the in vivo strategies, mechanisms, and conclusions generated thus
far by studying MYC's regulation of metabolism in various cancer models.
