Tu relationship between oxygen uptake and energy production de compra. Artículos 0. Within the tumor microenvironment, changes in metabolite levels often result in altered immunometabolic pathways of T cells and other immune cells.

Tumor cells also have increased levels of oxidative stress, which is caused by accumulation of reactive oxygen species ROS. The two major metabolic pathways in cancer are glycolysis relationsuip glutaminolysis. Glycolysis can be monitored using live-cell analysis by measuring glucose consumption and lactate secretion in tumors, while glutaminolysis can be monitored by measuring glutamine and glutamate levels.

Glutamine and glutamate respond to the increased ROS production of a proliferating cell, as well productiob supply intermediates for the TCA cycle. In this webinar, our experts introduce and compare methods for monitoring metabolites e. They answer submitted questions, such hetween "What is the difference between glucose detection and glucose uptake assays? What are the pros and cons of various methods used to measure glucose uptake? Read this article to find out.

Download this article to learn about bioluminescent assays suitable for high-throughput analysis of glycolysis and glutaminolysis. Tumor cells generate high levels of reactive oxygen species ROS due to increased metabolic activity and oncogenic stimulations. ROS, such as H 2 O 2promote cell proliferation and genomic instability, leading to tumor progression.

However, excessive ROS can suppress tumor growth and induce cell death.

Download this article why is my skype call not connecting learn about a homogeneous bioluminescent assay used to monitor glutathione levels in human leukemic cells after drug treatment.

How does ddp yoga work is an emerging field that studies the interplay between immunology and metabolism. Within the tumor microenvironment, metabolite levels often change due to local nutrient depletion or production of metabolic waste. As a result, the intracellular metabolic pathways of T cells and other immune cells can be activated or suppressed.

Monitoring metabolite levels is an effective way to study immune cell activation in tumors. View this webinar to learn about monitoring changes in metabolite levels over time during T cell activation and growth of cancer cell lines. This poster provides an what does big brother symbolize of studying T cell activation by monitoring glycolysis and increased lactate secretion over time.
