In the case of Noonan N-Ras mutants, it becomes apparent that Raf-MAPK activation is sufficient.
In 2012, John Tobias said: "If you look at any other pop culture phenomenon like if you look at the Teenage Mutant Ninja Turtles, for instance—it became popular at the time right around when Mortal Kombat became popular, and it had its highs and lows, and here they are once again talking about a major motion picture.
A single otolith eventually formed but, unlike in eis single mutants, it never became tethered to a sensory macula, and tapping experiments showed that it was untethered until at least 5 dpf (Fig. 3H,H′).
Rathke's pouch initially forms in these mutants [14], but it becomes severely dysmorphic (Fig. 2D) and cannot be visually identified at birth (not shown).
Although this difficulty can be overcome by PCR confirmation prior to the use of cultured mutants in each experiment, it becomes labor intensive in in vivo studies.
However, several exceptions are noted, and it becomes less predictable for mutants with lower aggregation propensities.
It should be noted that within each spot on selective plates, individual colonies of the mutant ultimately became visible above the parent lawn.
Not surprisingly, all mutant eggs became fully stained with the dye neutral red, in contrast to control ones (Fig. 3D).
Instead, their mutant defects became most apparent during pollen germination and, in the case of eif3h, pollen tube growth.
We next investigated if the cells that failed to develop into neurons in Ngn2GFP/GFP mutant mice, became glial cells.
