We recently conducted a chemical screen investigating the birth of HSCs in the aorta.
We also previously carried out a smaller scale screen investigating the differential requirement of KRAS mutant cells for ∼ 2 500 genes in the HCT-116 isogenic system using a pooled inducible shRNA library.
We exploited this in an initial screen, investigating the possibility that potential enhancers may reside in chromosomal segments made haploid by deletions, and these would become manifest by a change in the time required to recover from BS paralysis.
A previous genetic screen investigating early muscle development produced 13 independent mutant genes exhibiting a Pat (paralyzed and arrested elongation at the two-fold length of embryonic development) muscle phenotype.
While RNAi screens investigate the role of host genes in viral infections, microarray profiling shows the expression change of host genes in response to viral infections.
Genomics is an incredible technology for newborn and pre-natal screening, investigating the cause of a rare condition, and treating cancer, but for most healthy people it's still not particularly revolutionary.
Since then an impressive number of screens investigated host mechanisms utilized by pathogens [ 55, 78- 82].
These types of screening require adequate financial resources, a developed infrastructure, trained labour, and surveillance mechanisms for screening, investigating, treating, and following up on targeted women [ 5, 6].
During the preparation of this study, to our knowledge two other groups published screens investigating the role of miRNAs in NF-κB signaling [ 36, 37].
However, in vivo models can be time-consuming and expensive, limiting their use in routine screens investigating potential factors capable of promoting the invasive transition of DCIS.
