Project description:Libraries generated from microdissected kidney samples from the healthy pole of cancerous kidneys. Donors were from either sex. Libraries were generated using Sau3A I as anchoring enzyme. Data are provided after removal of linker derived sequences.

Project description:Purpose: Experiments were done in mice undergoing unilateral nephrectomy (UNx) and sham nephrectomy. At specific time points (24 hours and 72 hours) after surgery, the earliest first portion of the kidney proximal tubule (PT-S1) and the cortical collecting duct (CCD) were manually micro-dissected and utilized for transcriptomic analysis by single-tubule small sample RNA-Seq. Methods: We carried out RNA-sequencing in microdissected ealiest portion of proximal tubules (PT-S1) or cortical collecting duct (CCD) from mice with or without (sham) unilateral nephrectomy (UNx). Each group (Sham or UNx) has 3-5 biological replicates. Results and conclusion: RNA-Seq in microdissected PT-S1 at 24 hours showed that peroxisome proliferator-activated receptor alpha (PPARα) target genes were strongly upregulated. RNA-Seq in microdissected PT-S1 at 72 hours showed that cell cycle related genes were strongly upregulated. RNA-Seq in microdissected CCD at both 24 hours and 72 hours showed that cell cycle related genes were strongly upregulated.
Project description:Aim of the project was to evaluate several MS-comaptible detergents for processing fresh frozen (FF) and formalin fixed paraffin embedded (FFPE) microdissected human kidney tissue. Here we have evaluated sensitivity of the methods and their applicability on FF and FFPE tissues, as well as investigated for the appropriateness of the use of FFPE tissues.
Project description:Our laboratory's interest is in understanding the molecular principles that underlie the regional organization of the mammalian metanephric kidney. Our goal is to generate a detailed spatial map of the cellular expression of selected regulatory genes during mammalian kidney development. The goal of this study is to identify genes expressed during the morphogenesis of the nephron. By profiling two specific developmental nephron structures, we expect to identify genes expressed in both, and unique to each, which suggests they may play a role in the underlying mechanism responsible for the morphogenesis. Experiment Overall Design: Two early nephron structures, the renal vesicle and the s-shaped body, and the collecting duct system, were microdissected from E14.5 kidneys based on morphological criteria. Antibody and lectin staining together with RT-PCR were used for identity verification and for exclusion of contamination by other tissues. Samples are minimally pooled for amplification. A biological replicate is a single minimally pooled sample. RNA isolated from the collected structures was put through two rounds of T7-driven amplification to obtain the microgram quantities of cRNA needed for hybridization to Affymetrix microarrays. Detection of genes previously shown to be expressed in these early structures, such as Wt1, Wnt4 and Pax8, validates the data from the screen. The collecting duct sample serves as a reference sample for comparing the renal vesicle and s-shaped body comparison in this study.
Project description:Inflammatory breast cancer (IBC) is a unique clinical entity characterized by rapid onset of erythema and swelling of the breast often without an obvious breast mass. Many studies have examined and compared gene expression between IBC and non-IBC (nIBC), repeatedly finding clusters associated with receptor subtype, but no consistent gene signature associated with IBC has been validated. Here we examined microdissected IBC tumor cells compared to microdissected nIBC tumor cells matched based on estrogen and HER-2/neu receptor status.
Project description:We sought to decrease the cell type heterogeneity of kidney tissues to increase the resolution of methylation profiles. To that end, microdissected human kidney tissue from patients are used and hybridized on Illumina HumanMethylation450 BeadChip arrays. We extract genomic DNA from microdissected human kidney tubule samples. And used these genomic DNA for the Illumina 450K beads array.
