Coordinated genomic control of ciliogenesis and cell movement by Rfx2

ABSTRACT: We have performed a systems-level analysis of the RFX/Daf-19 family transcription factor, Rfx2. Using a combination of high-throughput sequencing of Rfx2-regulated transcripts and chromosomal binding sites, we provide a comprehensive accounting of the target genes by which Rfx2 controls ciliogenesis and cilia beating in vertebrates. RNA-seq: two biological replicates for control and RFX2 knockdown by morpholino injection, ChIP-seq: RFX2-GFP pulldown with GFP antibody, GFP only expression used as control

ORGANISM(S): Xenopus laevis

Next Generation Sequencing Analysis of Wild Type and Rfx2-/- Testicular Transcriptomes [ChIP-Seq]

Project description:Purpose: This study was carried out to determine the consequences of the Rfx2-/- genotype on spermatogenesis in the mouse Methods: DNA was extracted from decapsulated testes of 21 day old mice. ChIP sequencing was used to determine the binding sites of RFX2. Results: ChIP-Seq analysis identified ~880 binding sites of RFX2 near TSS. Conclusion: Spermatogenesis undergoes complete arrest just prior to the end of the round spermatid period of sperm development in mutant mice. Sequencing results showed that approximately 105 genes were downregulated 2 fold or more in the testes of mutant mice. Comparison of similar studies of targeted mutations in genes for other transcription factor demonstrate that Rfx2 has a large and nearly unique set of genes that depend on it directly or indirectly. A large number of downregulated genes are identified with cilia function. Testicular RFX2 binding sites were determined by deep sequencing using testes from 2 independentWT mice

Next Generation Sequencing Analysis of Wild Type and Rfx2-/- Testicular Transcriptomes at post natal day 21 [RNA-Seq P21]

Project description:Purpose: This study was carried out to determine the consequences of the Rfx2-/- genotype on spermatogenesis in the mouse Methods: RNA was extracted from decapsulated testes of 21 day old mixed background mice of either genotype. Deep sequencing was used to determine quantitative expression of the genomes from independent replicates of each genotype Results: RNA-Seq analysis identified some 105 genes that are down regulated at least 2-fold in Rfx2-/- testes, with ~50 being reduced at least 10-fold Conclusion: Spermatogenesis undergoes complete arrest just prior to the end of the round spermatid period of sperm development in mutant mice. Sequencing results showed that approximately 105 genes were downregulated 2 fold or more in the testes of mutant mice. Comparison of similar studies of targeted mutations in genes for other transcription factor demonstrate that Rfx2 has a large and nearly unique set of genes that depend on it directly or indirectly. A large number of downregulated genes are identified with cilia function. Testicular mRNA profiles were determined by deep sequencing using testes from 5 independent wild type and 6 independent Rfx2-/- mice

Next Generation Sequencing Analysis of Wild Type and Rfx2-/- Testicular Transcriptomes at post natal day 30 [RNA-Seq P30]

Project description:Purpose: This study was carried out to determine the consequences of the Rfx2-/- genotype on spermatogenesis in the mouse Methods: RNA was extracted from decapsulated testes of 29-30 day old mixed background mice of either genotype. Deep sequencing was used to determine quantitative expression of the genomes from independent replicates of each genotype Results: RNA-Seq analysis identified some 640 genes that are down regulated at least 2-fold in Rfx2-/- testes, with ~150 being reduced at least 10-fold Conclusion: Spermatogenesis undergoes complete arrest just prior to the end of the round spermatid period of sperm development in mutant mice. Sequencing results showed that approximately 640 genes were downregulated 2 fold or more in the testes of mutant mice.

Transcription Factor RFX2 Is a Key Regulator of Mouse Spermiogenesis

Project description:To identify RFX2-dependent genes during spermatogenesis, We chose 24-day-old wild-type and mutant testes samples. Spermiogenesis in mutants was normal before this time point while massive round spermatids detached from the tubules thereafter. RNAs were isolated from the total testicular cells.
