The phrase "alteration of oxygen" is correct and usable in written English.
It can be used in scientific or technical contexts, particularly when discussing changes or modifications related to oxygen, such as in chemical reactions or biological processes.
Example: "The alteration of oxygen levels in the atmosphere can significantly impact climate change."
Alternatives: "change in oxygen" or "modification of oxygen".
Thus, the regulation of VEGF by miR-20b may further tune tumor cells to adapt to the alteration of oxygen concentration.
Here, we further hypothesized that VEGF was targeted by miR-20b thus to additionally tune tumor cells to adapt to the alteration of oxygen concentration.
Such regulation model confers tumor cells to sense precisely the alteration of oxygen by the dynamic equilibrium between miR-20b and HIF-1α.
Changes in metabolic pathways and alteration of oxygen supply were suggested by upregulation of Egln3, Ldha, Aldoa, Eno1, Gapdh and Pgm2, indicating hypoxia.
The observed age dependent change in the cyt.aa3 patterns may indicate an alteration of oxygen metabolism at mitochondrial level and possible disturbance of electron transport of the oxidative pathway in deep hypothermic TCA.
During the maintenance stage of TH, the decrease in metabolic rate is equal to or greater than the decrease in cardiac output, and alteration of oxygen delivery is not a matter of concern.
We further addressed the question which fluxes might be most restrictive for nitrogen fixation and investigated the effect of small alterations of oxygen supply on the symbiotic nitrogen fixation capacity.
Alterations of oxygen tension results in the down-regulation of the majority MTB genes coupled with the up-regulation of a smaller subset [ 31].
Such combinations, looking at different functional compartments of the microcirculation, can integratively ascertain the distributive alterations of oxygen transport during sepsis, septic shock, and therapy that are not provided by conventional monitoring of systemic hemodynamic- and oxygen-derived variables.
The results suggest an alteration of muscle oxygen utilization, which is possibly due to the altered mitochondrial function and/or lactate accumulation in the FM population.
The reduction of the mitochondrial respiratory chain transfer efficiency, electronic leak, and ATP synthesis decline often occurred in aging, leading to mitochondrial abnormalities and alteration of reactive oxygen species levels (Green et al., 2011; Vendelbo and Nair, 2011).
