Sufficient access to nutrients is a fundamental requirement of cancer cells for survival and proliferation. Thus, tumor angiogenesis, which provides nutrients from the blood, is considered to be a hallmark of cancer and is a useful target for anti-cancer therapies. It is, however, increasingly clear that, in addition to extracellular sources of nutrients, cancer cells also efficiently utilize intracellular nutrients through the process of macroautophagy to drive oncogenic growth and survival.

Autophagic recycling of organelles, protein aggregates, and/or cytoplasm yields simple metabolites for use in cell growth or bioenergetics, and can destroy damaged structures to prevent toxicity. However, autophagy can be a double-edged sword: on the one hand, cancer cells exploit autophagy to enhance the nutrient supply, while on the other hand, too much autophagy leads to self-depletion and triggers cell death. At the same time, there is genetic evidence from mouse model systems that knockdown of certain canonical autophagic regulators, such as BECN1, ATG5, or ATG7, promotes tumor development. Opposing roles for autophagy in cancer—tumor-promoting versus tumor-suppressing—may result from differing interactions with cooperating oncogenes. Alternatively, the impact of autophagy in oncogenesis may be determined by differences in the formation of autophagic vacuoles carrying distinct cargos in a tissue- or starvation-specific manner.

There are multiple steps in autophagic pathways in which the specificity of the autophagic process is determined. Autophagy begins with the formation of a phagophore that can originate by de novo formation or from diverse sources, such as the plasma membrane, Golgi, endoplasmic reticulum, or outer mitochondrial membrane. A ubiquitin-like conjugation system generates an ATG12–ATG5 conjugate that, with ATG16L1, carries out a final E3-like conjugation of phosphatidylethanolamine (PE) to a family of proteins known as the LC3/GABARAP paralogs. The lipidated forms are then inserted into the autophagosome membrane where they recruit cargo by binding to adaptor proteins, such as SQSTM1/p62, NBR1, and CALCOCO2/NDP52, that seem to carry some level of specificity to certain cargos. Human cells have at least seven different LC3 paralogs (LC3A/B/B2/C and GABARAP/L1/L2), which indicates a biochemical richness that could lead to both specificity and redundancy.

Our recently published results show that differential engagement of LC3 paralogs identifies separate autophagic programs that exert either pro- or anti-tumorigenic activities in renal cell carcinoma. Both autophagic programs are regulated by the von Hippel-Lindau tumor suppressor protein (VHL) lost in renal cancer. VHL inhibits LC3B-mediated autophagy through induction of MIR204, which directly targets LC3B. In parallel, VHL, by inhibiting HIF, induces expression of LC3C, which carries tumor-suppressing autophagic activity (Fig. 1). The LC3B autophagic program supports tumor formation by VHL- renal cancer cells in orthotopic xenografts. LC3B expression is significantly increased in high-grade human ccRCC tumors as compared with lower grade tumors. The second program, mediated by a lesser-known LC3 paralog, LC3C, has tumor-suppressing activity. Knockdown of LC3C in VHL-expressing cells induces the formation of tumors that would otherwise be suppressed by VHL tumor suppressor function. In addition, LC3C expression is significantly higher in normal human kidney tissue as compared with ccRCC tumors.
Integrating our data with the established role of VHL in regulating angiogenesis produces a more global picture of VHL as a master tumor suppressor that regulates nutrient access for renal cancer cells from both extracellular and intracellular sources.

For the last 15 years, my laboratory has conducted mechanistic studies of signaling pathways and regulatory molecular mechanisms that regulate cancer cell survival and tumor growth in renal cancer.  In particular, we have focused our interests on the von Hippel-Lindau tumor suppressor (VHL), lost in majority of renal cancers, and autophagy. Renal cancer accounts for 2-3% of adult malignancies in the USA with clear cell renal carcinoma (ccRCC) as the main histological type. Current treatments include anti-angiogenic agents based on the understanding that the loss of VHL results in activation of HIF and VEGF. However, these treatments have a limited impact on survival. Thus, it is critical to identify novel pathways as specific targets for the development of new therapies. Autophagy is a tightly regulated homeostatic process which allows cells to eliminate defective structures and to recycle nutrients. In several cancers, including ccRCC, basic autophagy is elevated and necessary for tumor growth. Autophagy is also induced by inhibitors of angiogenesis, mTOR pathway or proteasome, leading to resistance to treatments. We established that in ccRCC, a specific LC3B-mediated autophagic program is activated by the loss of VHL, and LC3B activity contributes to tumor growth. Another autophagic program, mediated by LC3B paralog, LC3C, is stimulated by VHL and has tumor suppressing activity. Most recently we identified that two products of TRPM3 gene, microRNA 204 (miR-204) and transient receptor potential channel, TRPM3, have opposite roles in ccRCC. Mir-204 is induced by VHL and acts as a tumor suppressor inhibiting oncogenic autophagy, while TRPM3 acts as an oncogene and promotes oncogenic autophagy.
