Progressive cystic kidney degeneration underlies diverse renal diseases,
including the most common cause of kidney failure, autosomal dominant Polycystic
Kidney Disease (PKD). Genetic analyses of patients and animal models have
identified several key drivers of this disease. The precise molecular and
cellular changes underlying cystogenesis remain, however, elusive. Drosophila
mutants lacking the translational regulator Bicaudal C (BicC, the fly ortholog of
vertebrate BICC1 implicated in renal cystogenesis) exhibited progressive cystic
degeneration of the renal tubules (so called "Malpighian" tubules) and reduced
renal function. The BicC protein was shown to bind to Drosophila (d-) myc mRNA in
tubules. Elevation of d-Myc protein levels was a cause of tubular degeneration in
BicC mutants. Activation of the Target of Rapamycin (TOR) kinase pathway, another
common feature of PKD, was found in BicC mutant flies. Rapamycin administration
substantially reduced the cystic phenotype in flies. We present new mechanistic
insight on BicC function and propose that Drosophila may serve as a genetically
tractable model for dissecting the evolutionarily-conserved molecular mechanisms
of renal cystogenesis.
