一剪梅

红藕香残玉簟秋。轻解罗裳，独上兰舟。云中谁寄锦书来，雁字回时，月满西楼。花自飘零水自流。一种相思，两处闲愁。此情无计可消除，才下眉头，却上心头。

Gene knockdown

Gene knockdown is an experimental technique by which the expression of one or more of an organism's genes is reduced. The reduction can occur either through genetic modification or by treatment with a reagent such as a short DNA or RNA oligonucleotide that has a sequence complementary to either gene or an mRNA transcript.
