Project description:Ixodes pacificus, the vector of Borrelia burgdorferi (Bb) on the west coast, feeds on a variety of hosts including rodents, birds, and lizards. While rodents are reservoirs for Bb and can infect juvenile ticks, lizards are Bb-refractory. Despite the range of bloodmeals for I. pacificus, it is undetermined how larval host bloodmeal identity may affect future nymphal vector competence. Here, we conducted a transcriptome analysis on I. pacificus to determine whether and through what mechanisms host bloodmeal history affects vector competency of I. pacificus for the Lyme disease pathogen.
Project description:Remaining adult bees in colonies suffering from CCD at apiaries in Florida, California and Pennsylvania were collected during the winter of 2006-2007. The health of CCD colonies was scored at the time of collection as either ï¾severeï¾ or ï¾mildï¾ depending on the apparent strength of the colony. ï¾Historicalï¾ bees, collected prior to the appearance of CCD and hence ostensibly healthy, were collected in 2004 and 2005 from colonies set up on new equipment and not receiving any miticide treatments from apiaries of The Pennsylvania State University near State College, PA. A combination looped, common-reference microarray design was used to compare historical and CCD samples with each other; a blend of RNA isolated from healthy colonies (collected near Urbana, IL in July 2007) served as reference. The microarray experiment compared the guts of bees from mildly and severely afflicted colonies collected in apiaries experiencing CCD on the East Coast (Florida and Pennsylvania) and West Coast (California) with a common reference.
Project description:Gene expression changes in human populations exposed to chronic low level radiation have important implications. There are few areas around the world where human population is exposed to elevated levels of natural background radiation. The high level natural radiation areas (HLNRAs) of Kerala coast in south west India is unique for its wide variation in the background radiation dose (<1.0mGy to 45mGy/year). The areas with a background radiation dose of ≤ 1.5mGy/year are considered as normal level natural radiation areas (NLNRA), whereas areas with > 1.5mGy/year are considered as HLNRA. We used microarray analysis to find out global changes in gene expression in peripheral blood mononuclear cells (PBMCs) of individuals belonging to different HLNRA groups as compared to individuals from normal level natural radiation areas (NLNRA).
Project description:224 pairs of FASTQ files from metastatic Castration-Resistant Prostate Cancer (mCRPC) sequenced on HiSeq 4000 instruments. Patients were enrolled in the West Coast Dream Team study. Biopsies include various tissue sites including bone, soft tissue, and lymph node.

Project description:DNA strands have a complex and highly structured three-dimensional shape within the nucleus that has profound but poorly characterized impacts on transcriptional activity. Herein, we performed the first integrated deep Hi-C sequencing on 80 metastatic castration-resistant prostate cancer biopsy samples from the West Coast Dream Team consortium.
