Project description:Rsf1p is a putative transcription factor required for efficient growth using glycerol as sole carbon source but not for growth on the alternative respiratory carbon source ethanol. We use microarrays to determine the differences in the transcriptional program between the Δrsf1 mutant and the wild type during respiratory growth on glycerol as well as the transition to growth on glycerol as sole carbon source. Keywords: Mutant analysis during timecourse following switching carbon source from dextrose to glycerol
Project description:CyTOF data showed that 3-HAA significantly increased the percentage of F4/80hiCX3CR1loKi67loMHCIIhi macrophage and decreased the percentage of F4/80loCD64+PD-L1lo macrophages. scRNA-seq analyses demonstrated that 3-HAA administration was proved to regulate the function of M1 macrophages, M2 macrophages, and proliferating macrophages.
Project description:In this study, we investigate gene expression profile upon carbon source shifts in yeast. RNA-sequencing was performed in Sfp1 wild-type strain and K655/657 mutants growing in different carbon sources.
Project description:Purpose: We explore gene expression changes when Neurospora crassa wild type responds to different carbon sources in Vogel's medium. Method: We obtained mRNA samples of Neurospora crassa WT in Vogel's minimal medium (VMM) with different carbon source and used RNA-seq technique to measure the trancriptome changes. Results: We identified many genes of transcription factors and enzymes that were up regulated or down regulated in response to the different carbon stimulation. Conclusion: Our data represents a systematic transcriptome profiling of filamentous fungi on different carbon source and identify COL-26 as a critical regulator in degradation of starch components.
Project description:Precise regional patterning is fundamental to tissue organization, yet the spatial logic that governs it remains poorly defined for many tissues. In the vertebrate retina, molecular domains along the dorsoventral and nasotemporal axes provide positional cues for regional specializations such as the high-acuity area (HAA). We combined multiplexed in situ hybridization data with single-cell transcriptomic data to create quantitative two-dimensional maps of developing retinal cells. In the developing chicken retina, this approach resolved sharp expression boundaries of genes involved in patterning, and revealed novel candidates enriched in the anlagen of the HAA. Comparative analysis of chicken, mouse, and human data demonstrated conserved axis-based programs, but distinct fine-scale organization consistent with presence/absence of an HAA. Here, we show that spatial reconstruction from scRNA-seq data, anchored by experimental benchmarks, enables comparative 2D topographic mapping of gene expression across species and provides a generalizable strategy to investigate the spatial logic of molecular organization in developing tissues.
