MetabolomicsToxoplasma gondii metabolic flexibility in response to iron deprivation

Iron is an essential nutrient for many critical cellular processes. As a consequence of diverse and dynamic host environments, the obligate intracellular parasite Toxoplasma gondii must adapt to iron limited conditions. To investigate the adaptations critical to parasite survival under these cond...

MetabolomicsSystem Xc- exacerbates metabolic stress under glucose depletion in oral squamous cell carcinoma

OBJECTIVE: Emerging evidence suggests that glucose depletion (GD)-induced cell death depends on system Xc-, a glutamate/cystine antiporter extensively studied in ferroptosis. However, the underlying mechanism remains debated. Our study confirmed the correlation between system Xc...

TranscriptomicsGene expression profiling of the effect of elevated TRIB3 expression on the transcriptional response to glucose deprivation
Gene expression profiling of HEK293-derived cell lines that are stably transfected with either a tetracycline-inducible TRIB3 expression construct (TRIB3-293 cells), tetracycline-inducible ATF4 expression construct (ATF4-293 cells) or the corresponding empty vector (Vector-293 cells). Samples from t...

MetabolomicsThe effects of oligomycin administration and glutamine deprivation on metabolic profile of MCF7 breast cancer cell line measured using [1,2-13C2]-D-glucose and [U-13C5]-L-glutamine as tracers
This study aims to establish a comprehensive, genome-scale metabolic model (GSMM) combining different omics data of different regulatory levels of breast cancer cells in order to elucidate the way that these regulatory levels affect or determine each other. Together with transcriptomics, proteomics ...

MetabolomicsAnalysis of glucose-independent metabolic pathways associated with anti-proliferative effect of metformin and their reversibility in liver cancer cells

Several studies indicated anti-cancer effects of metformin in liver cancer. This was attributed to the activation of LKB-AMPK axis, which is associated with anti-hyperglycaemic effect and cytotoxicity. However, glucose- and central carbon-independent effects of metformin ...

ProteomicsRole of 4EBP1/2 in the response to glucose deprivation
We investigated the function of the mTORC1 substrates and mRNA translation regulators 4EBP1/2 in the response to glucose deprivation. We uncovered that targeting 4EBP1/2 expression had a direct impact on the survival rates of cells challenged with glucose deprivation. To further define the mechanism...

TranscriptomicsTime resolved ribosome profiling study of oxygen and glucose deprivation of rat pheochromocytoma cells
Oxygen and glucose metabolism plays a pivotal role in many (patho)physiological conditions. In particular, oxygen and glucose deprivation (OGD) occurs during ischemia and stroke, resulting in extensive tissue injury and cell death. We applied time-resolved ribosome profiling technique to assess earl...

TranscriptomicsSteroid Receptor Coactivator 1 is an Integrator of Glucose and NAD(+)/NADH Homeostasis
SRC-1 affects the expression of complex I of the mitochondrial electron transport chain, a set of enzymes responsible for the conversion of NADH to NAD(+). NAD(+) and NADH were subsequently identified as metabolites that underlie SRC-1's response to glucose deprivation. Knockdown of SRC-1 in glycoly...

TranscriptomicsExpression analysis of the glucose deprivation-induced human tumor cell responses
The tumor microenvironment is characterized by low glucose and hypoxia. It is well known that changes in the tumor microenvironment, such as hypoxia and low glucose, can increase the production of VEGF. Although the role of hypoxia in the regulation of VEGF production is well understood, the mechani...

TranscriptomicsTranscription profiling of human cancer cells treated with unfolded protein response modulators under endoplasmic reticulum stress conditions
The unfolded protein response (UPR) is a cellular defense mechanism against glucose deprivation, a cell condition that occurs in solid tumors. A key feature of the UPR is the activation of the transcription program that allows the cell to cope with endoplasmic reticulum (ER) stress. We used micoarra...
