Comparative high-throughput RNAi screening methodologies in C. elegans and mammalian cells

The discovery of RNAi in Caenorhabditis elegans has generated a paradigm shift in how research is performed. Targeted gene knockdown using high throughput screening approaches is becoming a routine feature of the scientific landscape, and researchers can now evaluate the function of each gene in the genome in a relatively short period of time. This review compares and contrasts high throughput screening methodologies in C. elegans and mammalian cells and highlights the breadth of applications of this technology.

► We review recent technological advances in RNAi screening.
► Comparison of C. elegans and mammalian cell culture screens.
► Highlight the pros and cons for selected screening approaches.
