Effect of mce3R deletion on Mycobacterium tuberculosis response to acidic pH and cholesterol

Project description:The purpose of this study was to determine (i) the interplay between Mycobacterium tuberculosis response to acidic pH and cholesterol, two signals experienced concurrently by the bacterium during host colonization, and (ii) the role of the transcription factor Mce3R in regulation of this response.

Mycobacterium tuberculosis transcriptional responses to acidic pH and carbon source

Project description:The purpose of this study was to examine how Mtb integrates acidic pH and available carbon sources as environmental cues to regulate its metabolism and growth rate. RNA-seq transcriptional profiling of M. tuberculosis growing at acidic or neutral pH, in pyruvate or glycerol, was examined. These studies identified carbon source-dependent and -independent pH-dependent adaptations. Mtb strain CDC1551 was grown in standing T-75 flasks in 40 mL of medium seeded an initial OD of 0.1. We examined medium in four conditions pH 7.0 10 mM glycerol, pH 5.7 10 mM glycerol, pH 7.0 10 mM pyruvate, pH 5.7 10 mM pyruvate. Following 3 days of incubation at 37C, RNA was isolated from the bacterial cultures and used for RNA-seq.

PrrA modulation of Mycobacterium tuberculosis response to acidic pH and high chloride levels is critically regulated by serine/threonine protein kinases

Project description:The purpose of this study was to understand how prevention of serine/threonine protein kinase (STPK) phosphorylation of PrrA impacts PrrA modulation of M. tuberculosis transcriptional response to acidic pH and high chloride levels.

The Rfg1 and Bcr1 transcription factors regulate acidic pH-induced filamentous growth in Candida albicans

Project description:To investigate the function of Rfg1 in sensing acidic pH and regulating filamentation in C. albicans, we performed the global gene expression profile analysis of WT and rfg1/rfg1 mutant.We reveal that Rfg1 is an essential acidic pH sensor in C. albicans. Rfg1 regulates filamentous growth in acidic pH condition via co-regulation of Rim101-Phr1 pathway, cAMP signaling pathway,and the transcription factors Bcr1, Efg1, Flo8, and Hgc1.

microarray analysis in SREBP2-knockdown cells under low pH (pH 6,8) culture conditions

Project description:The conditions of the tumor microenvironment, such as hypoxia and nutrient starvation, play critical roles in cancer progression. However, the role of acidic extracellular pH in cancer progression is not studied as extensively as that of hypoxia. Here, we show that extracellular acidic pH (pH 6.8) triggered activation of sterol regulatory element-binding protein 2 (SREBP2) by stimulating nuclear translocation and promoter binding to its targets along with intracellular acidification. Interestingly, inhibition of SREBP2, but not SREBP1, suppressed the upregulation of low pH-induced cholesterol biosynthesis-related genes. Moreover, acyl-CoA synthetase short-chain family member 2 (ACSS2), a direct SREBP2 target, provided a growth advantage to cancer cells under acidic pH. Furthermore, acidic pH-responsive SREBP2 target genes were associated with reduced overall survival of cancer patients. Thus, our findings show that SREBP2 is a key transcriptional regulator of metabolic genes and progression of cancer cells, partly in response to extracellular acidification.

MtrA regulation of essential peptidoglycan cleavage in Mycobacterium tuberculosis during infection [pH]

Project description:The success of Mycobacterium tuberculosis (Mtb) is largely due to its ability to withstand numerous stresses imposed by host immunity. Here, we present a data-driven model that captures these adaptive mechanisms and reveals the dynamic interplay of host-derived stresses and genome-encoded regulatory programs in Mtb. The model captures the genome-wide distribution of cis-acting gene regulatory elements and the conditional influences of transcription factors at those elements to elicit environment-specific responses. Analysis of transcriptional responses that may be essential for Mtb’s survival in acidic conditions identified regulatory control by the MtrAB two-component signal system. This data is a comparison of transcriptional differences (RNA-seq) between low pH (pH 5.6) and neutral pH (pH7) of Mtb
