There are many types of urea cycle and related disorders (see the table) as well as many. (msdmanuals.com)

Traditionally, models of gliomas are 2-dimensional cell lines and only represent certain subtypes of the highest-grade glioma, glioblastoma. (upmc.edu)
We conducted a global transcriptional analysis of human glioblastoma cell response to infection with WNV during peak virus production to determine the crucial virus-host interactions that take place during a severe neuroinvasive attack and identify putative mechanisms involved in WNV pathogenesis. (cdc.gov)
In this study, human glioblastoma (A172) cells were found to be a useful laboratory model for investigating WNV infections. (cdc.gov)
A172 (human glioblastoma) cells were maintained at 37°C in Dulbecco modified Eagle medium (Sigma, St. Louis, MO, USA) supplemented with 10% fetal calf serum. (cdc.gov)

Many of the enzymes in the TCA cycle are regulated by negative feedback from ATP when the energy charge of the cell is high. (citizendium.org)
Also the enzymes citrate synthase, isocitrate dehydrogenase and alpha-ketoglutarate dehydrogenase, that regulate the first three steps of the TCA cycle, are inhibited by high concentrations of ATP. (citizendium.org)
Several enzymes are also negatively regulated when the level of reducing equivalents in a cell are high (high ratio of NADH/NAD+). (citizendium.org)

The generation of hydroxyl by killer cells is critical to their cytotoxic capability. (silvermedicine.org)
Synovial sarcoma is a high-grade soft tissue malignancy, for which current cytotoxic chemotherapies provide limited benefit. (nature.com)

Excess iron is a much greater concern in horses because free iron ions (Fe2+) act as oxidants causing damage to DNA, cell membranes, and other structures. (madbarn.com)
