Project description:Malassezia restricta and Staphylococcus epidermidis are dominant members of the human skin microbiome that interact closely, yet the molecular basis of their interaction remains unclear. In this study, we investigated how S. epidermidis-derived acetic acid (AcOH) influences chromatin organization in M. restricta. We generated the first high-resolution three-dimensional genome architecture map of M. restricta using in situ Hi-C and identified putative centromeric regions based on inter-chromosomal contact patterns. Exposure to AcOH, either by co-culture or direct treatment, led to large-scale chromatin decompaction and enhanced centromere clustering. These findings indicate that AcOH acts as an epigenetic modulator, inducing significant reorganization of nuclear architecture in M. restricta. This dataset provides a resource for understanding interkingdom interactions and the epigenetic effects of bacterial metabolites on fungal chromatin structure.
Project description:Purpose: Understanding the Mechanism of Action of the Anti-Dandruff Agent Zinc Pyrithione against Malassezia restricta. Methods: The transcriptome profile of the ZPT-treated M. restricta cells compared to that of untreated cells were generated by RNA-Seq using Illumina HiSeq. Generated raw reads that passed quality filters were mapped to the reference genome. Mapped reads were counted by featureCounts in Subread package v1.4.3 and the relative transcript abundance was TPM-normalized. Results: A number of genes were differentially expressed in the ZPT-treated cells, which include genes involved in zinc transporter, mitochondirial function, TCA cycle, electron transport chain and lipase.

Project description:Purpose: Understanding the mechanism of action of lauryl betaine against Cryptococcus neoformans and Malassezia restricta. Methods: The transcriptome profile of the lauryl betaine-treated cells compared to that of untreated cells were generated by RNA-seq Illumina Hiseq. Results: A number of genes were differentially expressed in the lauryl betaine-treated cells, which include genes involved in ergosterol biosynthetic pathway.
Project description:The skin commensal yeast Malassezia is associated with several skin disorders. To establish a reference resource, we sought to determine the complete genome sequence of Malassezia sympodialis and identify its protein-coding genes. A novel genome annotation workflow combining RNA sequencing, proteomics, and manual curation was developed to determine gene structures with high accuracy.
Project description:To understand ketoconazole resistance mechanism in M. restricta, we investigated differentially expressed genes in the azole resistant isolates using transcriptome profile. Transcriptomes of ketoconazole susceptible and resistant M. restricta cells in the absence and precence of ketoconazole were compared and analyzed by RNA sequencing.
