Transcription factor AmyR and Molecular brake Hat1 modulate amylase gene expression in Penicillium oxalicum

Project description:The goals of this study are to compare different gene expressions for Penicillium oxalicum wild type strain (WT), Hat1 deletion strain (ΔHat1) and AmyR deletion strain (ΔAmyR) in 2% starch as carbon sources. The correlation analysis results between the various samples showed that the gene expression levels of the wild strain and the ΔHat1 strain were significantly different, and the gene expression levels between ΔAmyR and the wild strain were also significantly different. The deletion of Hat1 significantly up-regulates the expression levels of amylase genes of Penicillium oxalicum, and the absence of AmyR can significantly down-regulate the expression level of amylase genes genes, indicating that Hat1 and AmyR can cause a difference in amylase synthesis by affecting the expression of amylase genes. The information provided by this study indicates that Hat1 and AmyR functions are necessary for the amylase activity of Penicillium oxalicum.

Transcription factor CrzA modulate fungal development and cellulolytic gene expression in Penicillium oxalicum

Project description:The goals of this study are to compare different gene expressions for Penicillium oxalicum wild type strain (WT), CrzA deletion strain (ΔCrzA) and CrzA recover strain (ReCrzA) in 2% starch as carbon sources. The correlation analysis results between the various samples showed that the gene expression levels of the wild strain and the RecrzA strain were similar, and the gene expression levels between ΔcrzA and the wild strain were significantly different. The deletion of CrzA significantly down-regulates the expression levels of conidia pigment synthesis genes, and spore wall synthesis-related genes of Penicillium oxalicum, and also has a regulatory effect on the expression levels of genes related to the sporulation process. And the absence of CrzA can broadly down-regulate the expression level of cellulase-encoding genes, indicating that CrzA can cause a decrease in cellulase synthesis by affecting the expression of cellulase-encoding genes. The information provided by this study indicates that CrzA function is necessary for the mycelial development and cellulase activity of Penicillium oxalicum.

HAT1 coordinates histone production and acetylation via H4 promoter binding

Project description:The energetic costs of duplicating chromatin are large and therefore likely depend on nutrient sensing checkpoints and metabolic inputs. By studying chromatin modifiers regulated by epithelial growth factor, we identified histone acetyltransferase 1 (HAT1) as an induced gene that enhances proliferation through coordinating histone production, acetylation and glucose metabolism. In addition to its canonical role as a cytoplasmic histone H4 acetyltransferase, we isolated a HAT1-containing complex bound specifically at promoters of H4 genes. HAT1-dependent transcription of H4 genes required an acetate-sensitive promoter element. HAT1 expression was critical for S-phase progression and maintenance of H3 lysine 9 acetylation at proliferation-associated genes, including histone genes. Therefore, these data describe a feed-forward circuit whereby HAT1 captures acetyl-groups on nascent histones and drives H4 production by chromatin binding to support chromatin replication and acetylation. These findings have important implications for human disease, since high HAT1 levels associate with poor outcomes across multiple cancer types.

Streptococcus gordonii gene response to the binding of human salivary amylase.

Project description:Streptococcus gordonii, an important primary colonizer of dental plaque biofilm, specifically binds to salivary amylase via the surface-associated amylase-binding protein A (AbpA). We hypothesized that amylase binding to S. gordonii modulates expression of chromosomal genes, which could influence bacterial survival and persistence in the oral cavity. Gene expression profiling by microarray analysis was performed to detect differentially expressed genes in S. gordonii strain CH1 in response to the binding of purified human salivary amylase as compared to exposure to heat-denatured amylase. Selected genes found to be differentially expressed were validated by qRT-PCR. Five genes from the fatty acid synthesis (FAS) cluster were highly (10-35 fold) up-regulated in amylase treated S. gordonii CH1 cells compared to the denatured-amylase treated cells. An abpA-deficient strain of S. gordonii exposed to amylase did not show a similar response in FAS gene expression as observed in the parental strain. Predicted phenotypic effects of amylase binding to S. gordonii strain CH1 associated with increased expression of FAS genes leading to changes in fatty acid synthesis were noted, as evidenced by increased bacterial growth, survival at low pH, and resistance to triclosan. These changes were not observed in the amylase exposed abpA-deficient strain, suggesting for the role of AbpA in amylase-induced phenotype. These results provide evidence that the binding of salivary amylase elicits a differential gene response in S. gordonii, resulting in a phenotype adjustment that is potentially advantageous for bacterial survival in the oral environment.

Alpha-amylase overproduction in Streptomyces lividans

Project description:The gene aml encoding alpha-amylase in Streptomyces lividans was cloned in the multicopy plasmid pIJ486, generating plasmid pAMI11. Plasmid pAMI11 and pIJ486 were propagated in S. lividans TK21 to obtain S. lividans TK21(pAMI11) and its isogenic strain S. lividans TK21(pIJ486). Transcriptional profiling of the bacterium that overproduces alpha-amylase mainly resulted in the upregulation of genes involved in the biogenesis and function of ribosomes, together with the upregulation of the genes involved in the redox processes, the ABC transporters, the central carbon, aminoacid and purine /pyrimidine metabolism. Moreover, some genes involved in oxidative stress were upregulated. The number of genes downregulated was much lower than the upregulated ones. Therefore, bacteria respond by favouring alpha-amylase overproduction that apparently does not cause damage to the cell.
