Studies of loss of function situations in mice have contributed to the understanding of epigenetic regulators in early embryonic lineage decisions.
Despite yielding statistically significant differences, in hyperfiltration and normal renal function situations, MCQ presents a mean ± SD closer to those of the isotopic method and lower bias and CIs in the estimation of renal function.
Conversely, in a gain-of-function situation MGM overexpression was able to activate the Wg target senseless (Figure 2J).
The interaction between Vent1, Vent2, and Gsc had never been tested in a triple loss-of-function situation, which proved an interesting experiment.
To identify positive epistatic effects on leaf growth, we analyzed pairwise perturbations of 13 genes positively affecting final leaf size in a gain- or loss-of-function situation (Table 1) by measuring the individual and total leaf area.
In this context it is of interest that some human VMCM patients that harbor p.R915H mutations suffer from ventricular septal defects, even though the hyper-phosphorylated state of the human mutant proteins might not be directly comparable to the loss-of-function situation of tie-2 mutant zebrafish embryos.
Therefore, in conjunction with the findings that tie-2 mRNA levels are severely reduced and immunohistochemistry using an anti-zebrafish antibody could not detect Tie-2 protein in 2-day-old mutants at all, we conclude that tie-2 hu1667 represents a loss-of-function situation.
The opposite phenotype is seen in loss-of-function situations of the Dpp/Mad pathway.
However, both genes are crucial in later stages and show synergistic effects in the maintenance of endocardial-myocardial interaction in loss-of-function situations, a phenotype that is similar to the phenotype seen in Tie-2 −/− mice, which have poor association between endothelial cells and the myocardium.
According to social psychology's fundamental attribution error, we explain our own poor outcomes as a function of situation, but interpret the poor outcomes of others as due to their personality.
