RNA-seq Analysis of Sex Differences in Mouse Proximal Tubule Gene Expression


Multiomics Analyses Reveal Sex Differences in Mouse Renal Proximal Subsegments.

J Am Soc Nephrol 2023, PMID: 36758122


Brief Method: kidneys from 6-week-old WT male mice and female mice (only female proximal tubules were included in this database) were perfused via the left ventricle with perfusion buffer (135 mM NaCl, 1 mM Na2HPO4, 1.2 mM Na2SO4, 1.2 mM MgSO4, 5 mM KCl, 2 mM CaCl2, 5.5 mM glucose, 5 mM HEPES, pH 7.4). kidneys were then sliced and dissociated in perfusion buffer supplemented with collagenase B. Microdissection were performed under the stereomicroscope equipped with on-stage cooling. After washes in ice-cold PBS, the microdissected renal tubules were transferred to Trizol reagent for RNA extraction. cDNAs were synthesized by SMARTer V4 kit (Clontech) and cDNA libraries were constructed for paired-end sequencing and sequenced on Illumina HiSeq3000 platform. Reads were mapped to mouse Ensembl Genome by STAR and transcript abundances were calculated in the units of transcripts per million (TPM) using RSEM (https://github.com/deweylab/RSEM).

ATAC-seq anaylsis of proximal tubules

Use the search box to find a genomic locus:
1) A locus in genome coordinates (for example, chr6:55,228,899-55,454,879)
2) A gene symbol (e.g., Slc34a1) or multiple space-sperated gene symobls (e.g., Aqp1 Slc34a1))
