Stanley Young\, Asst. Director for Bioinformatics\, Natio nal Institute of Statistical Sciences\, Research Triangle Park\, NC. Disco very of biologically active compounds is often accomplished by screening l arge collections of compounds. Very few compounds are expected to have the activity of interest so testing compounds individually generates large am ounts of mostly uninformative data. Dorfman (1943) proposed testing pools of individuals when looking for rare events. There is relatively little li terature on using pools for drug discovery\; informal conversations indica te that testing of pools has a checkered history. There is a level of para noia that active compounds will be missed. There is also the somewhat comp licated logistics of the decoding process. So what are the statistical issues with pooling? There is some guiding theory for determining the num ber of compounds in a pool\, k=SQRT(1/p) where p is the probability that a compound will be active. We know a lot about the structural features of o ur compounds. Can we use that knowledge to select compounds to pool togeth er? What about the expensive\, retesting decoding process? Can we use the chemical structures of compounds in a pool to 'put a statistical finger' o n the active compound(s) in an active pool? This presentation addresses tw o questions: How to use chemical structural information to guide the const ructing of pools? How to build a mathematical model for the prediction of biological activity when the tested objects are mixtures of compounds? It is 'a work in progress' so I will comment on future research directions. T his is very much 'team research.' I'm working with Prof. Jackie Hughs-Oliv er and graduate students at NCSU. Some of this work is funded by the NIH R oad Map project.\n DTSTART:20071024T183000Z DTEND:20071024T193000Z LOCATION:Duff Medical Building\, CA\, QC\, Montreal\, H3A 2B4\, 3775 rue Un iversity SUMMARY:Design and analysis of pooled high throughput screening data URL:/channels/event/design-and-analysis-pooled-high-th roughput-screening-data-27611 END:VEVENT END:VCALENDAR
