This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. OVERVIEW ***Please note the Tables and Figures mentioned below would not reproduce in this format. Please see attachments sent with the paper copy.*** Core B served the VCII both by providing services to individual VCII laboratories (see Utilization and also Publications) as well as by playing a central role in bringing emerging technologies that are important for VCII investigators (Emerging Technologies). General background on the Microarray Facility is also included (General Background Information). UTILIZATION Services provided to individual VCII labs amounted to 65 Affymetrix GeneChips and 25 hours of bioinformatics service (Table I, Figure 1). Table I Services provided to individual laboratories. 'Hours'refers to bioinformatics service. Figure 1 GeneChip (left) and RNA assessment services (right) provided to VCII laboratories as a percentage of total services. Total utilization of the Microarray Facility consisted of (see also Figure 2) -Experimental design consultations with 18 investigators -Completion of 19 microarray projects (277 GeneChips) -Performed 163 RNA assessments: 79 PicoChips, 81 NanoChips, 3 small RNA's chip (new service, implemented, August, 2008) PUBLICATIONS Publications by VCII Faculty on VCII-related projects that were supported by Core B: 1.

PMID: 18500752 [PubMed - in process] EMERGING TECHNOLOGIES Emerging technologies, particularly Affymetrix Exon and Gene arrays as well as next generation sequencing are important for VCII research programs, for example, the VCII external advisory committee (EAC) made a firm recommendation that we provide next generation sequencing technlogy to the VCII. Next generation sequencing Core B is heavily involved in efforts to bring next generation sequencing to UVM (Table 2). Tim Hunter of Core B initiated the process by inviting speakers to UVM. Dr. Budd suggested we apply for an NCRR instrumentation award. The INBRE-funded Vermont Genetics Network took on a leadership role in this process. Table 2. Events related to bringing next generation sequencing technology to UVM. Affymetrix exon and gene arrays Affymetrix exon and gene arrays are emerging as a replacement for Affymetrix 3'arrays. Tim Hunter and Scott Tighe brought these arrays to UVM. Scott Tighe identified a software platform (BioTique Systems XRAY) that supports this technology. The Vermont Genetics Network provided a part time bioinformatics analyst (Dr. Julie Dragon) who is in charge of the exon/gene array pipeline. Dr. Bond is developing an R/Bioconductor pipeline that will give our exon and gene array pipeline the flexibility that we provide for 3'arrays. Network Analysis Core B played a leadership role in bringing Ingenuity IPA to UVM. We evaluated products, coordinated the purchase, and offered special workshops for VCII laboratories.
