Project description:To characterize the cellular composition of the lung tissues of OP patient, we collected lung samples for scRNA-seq from one patient with OP, one healthy control
Project description:Organophosphate resistant and susceptible tick larvae from laboratory strains of the southern cattle tick, Rhipicephalus (Boophilus) microplus were exposed to low doses of the organophosphate (OP) acaricide, coumaphos. Serial Analysis of Gene Expression (SAGE) was used to analyze differential gene expression in response to OP treatment and to compare the responses in OP-treated and untreated resistant and susceptible tick larvae. ** note: Contact person is Felix D. Guerrero. email: felix.guerrero@ars.usda.gov Keywords: SAGE, acaricide response, organophosphate.

Project description:We compared gene expression profile between healthy-donor peripheral monocytes and glioblastoma-patient peripheral monocytes as well as glioblastoma-patient peripheral monocytes with matched tumor-infiltrating myeloid cells.
Project description:Aims of study: (1) To identify systemic differences in osteoarthritic (OA) bone that contribute to OA pathogenesis. (2) Identify novel osteoporotic (OP) bone-related disease genes. Study involved comparison of trabecular bone extracted from the intertrochanteric (IT) region of the proximal femur (PF) from OA, OP and normal/control (CTL) individuals. Bone was obtained from OA and OP individuals at surgery for total hip replacement and from CTL individuals at autopsy. Keywords: Bone tissue comparison, diseased versus non-diseased, factorial design, linear modelling
Project description:We performed microarray analysis on ISCU myopathy patient muscle biopsies to identify transcriptional modulation of pathways involved in the cellular response to Fe-S cluster deficiency. We included RNA samples from five healthy control individuals as well as three different ISCU myopathy patients.
Project description:Patients with chronic kidney disease (CKD) have significantly increased morbidity and mortality resulting from infections and cardiovascular diseases. Since monocytes play an essential role in host immunity, this study was directed to explore the gene expression profile and to identify differences in activated pathways in monocytes relevant to the pathophysiology of atherosclerosis and increased susceptibility to infections. Monocytes from CKD patients (stages 4 and 5, eGFR <20 ml/min x 1.73 m2) and healthy donors were collected from peripheral blood. Microarray gene expression profile was done and data were interpreted by Genespring software and Panther tools website. Western blot was done to validate the pathway members. The results demonstrated that 487 and 258 genes were differentially up- and down regulated respectively in the patient group. Pathways involved in the inflammatory response were highly expressed and the Wnt/β- catenin signaling pathway was the most significant pathway expressed in the patient group (P=0.02). Since this pathway has been attributed to a variety of inflammatory manifestations, the current finding may contribute to dysfunctional monocytes in CKD patients. To develop strategies to interfere with this pathway may improve host immunity and prevent cardiovascular complications in CKD patients. Six gene expression Affymetrix chip were used. Three for each group
