Exhaustive selection of RNA aptamers against complex targets

A method of identifying RNA ligands which bind to a target molecule by treating a first pool of RNA ligands that collectively bind more than one target under conditions effective to reduce the concentration or eliminate the presence of one or more predominate target-binding RNA ligands from the first pool of RNA ligands; amplifying the RNA ligands in the treated first pool, thereby forming a second pool of RNA ligands that is enriched in one or more non-predominate target-binding RNA ligands of the first pool but not the one or more predominate target-binding RNA ligands thereof; and identifying one or more predominate target-binding RNA ligands that are present in the second pool at a higher concentration than other target-binding RNA ligands. Oligonucleotides and kits which can be used in practicing the present invention are also disclosed, as are aptamers that bind to a heat shock factor protein and their use.

Methods of treating cancer using a heat shock factor activity inhibitor

A disease treatment is provided by controlling the expression of a protein induced by a heat shock factor.The novel compound benzo-1,3-dioxole provides an inhibitor of HSF activity or an inhibitor of inducing the production of a protein regulated by HSF, which inhibits the activity of a heat shock factor, a transcriptional regulatory factor, thereby in turn inhibiting transcription of a structural gene having a heat shock element sequenc in the gene region for transcriptional regulation into RNA, and thus inhibiting translation of the gene into a protein, and resulting in inhibition of inducing production of RNA or protein encoded by the gene. It also provides a drug for treating or preventing cancer through thermotherapy and a drug for treating or preventing stress diseases such as depression.

Compositions and methods for regulating cellular protection

The invention provides a method of inducing a protective response in cells by activating a heat shock response, via heat shock transcription factor (HSF), without stressing the cells. The invention is based on the surprising discovery that HSF can be activated in non-stressed cells by disrupting interaction with the repressive cognate protein, Hsc70. As described herein, non-steroidal anti-inflammatory drugs (NSAID), including salicylic acid and ibuprofen, can stimulate HSF DNA binding, Hsp70 transcription and Hsp70 protein synthesis in non-stressed cells. By activating HSF, the degenerative effects of certain neurodegenerative proteins such as polyglutamine repeat proteins (Huntington's disease) and the α-synuclein protein (Parkinson's disease) can be offset. The invention thus provides a method of ameliorating symptoms of neurodegenerative disease.
