What is the expected number of mutants in a stochastically growing colony once it reaches a given size, N? This is a variant of the famous Luria Delbruck model which studies the distribution of mutants after a given time-lapse.
However, while the Hyp mice maintain an elevated plasma parathyroid hormone concentration under basal conditions (in response to a decreased plasma calcium), the parathyroid activity of the mutants after a more severe hypocalcemic challenge is attenuated, resulting in a significantly different model of linear correlation.
Iterating this process will increase the degree of sorting of the sub-population and remove almost all the slow worms (mutants) after a few trials.
Conversely, the absence of cell elongation of the Inv dinG mutants after a shift to LB contrasts with their plating defect suggests late, possible cumulative defects.
In fact, a specific defect in the replication of the rDNA repeat was uncovered in sgs1 ts slx4 double mutants after a shift to the restrictive temperature (Kaliraman and Brill 2002).
High resolution AFM imaging carried out on 15 cells from 3 independent experiments did not reveal any formation of singular cell surface CS in these different mutants after a heat shock at 42°C for 1 h (Additional file 6: Figure S5).
Importantly, the apoptotic effects after mutant p53 knockdown were completely abrogated in MDA-MB-468 cells reconstituted with an exogenous expression of 5′-UTR-deleted R273H mutant p53 after a knockdown of endogenous mutant p53 using an siRNA that target the 5′-UTR of the endogenous mutant p53.
As above, the mortality risk of a mutant of quality A after mating with a partner of quality B is given by (30) m ^ A B = m A (c ^ A B ). Since mutants always mate with other mutants, the brood productivity of a mutant pair of qualities A and B is (31) b A B = b (c ^ A B + c ^ B A ).
To further confirm that TORC2 function is essential for Ypk1-mediated phosphorylation of ceramide synthase, Lac1 phosphorylation was monitored in TOR2 cells and in a tor2-as mutant after addition of a specific tor2-as inhibitor, BEZ-235 (Kliegman et al., 2013).
Its expression, similar to those of Attacins and Cecropins, is decreased in Toll pathway mutants after an immune challenge with a mixture of Escherichia coli and M. luteus [7], [11], possibly reflecting a synergy between Toll and imd pathways in the case of mixed infections [12].
