Signal Transduction Pathway

Famous quotes containing the words signal and/or pathway:

“Certainly the effort to remain unchanged, young, when the body gives so impressive a signal of change as the menopause, is gallant; but it is a stupid, self-sacrificial gallantry, better befitting a boy of twenty than a woman of forty-five or fifty. Let the athletes die young and laurel-crowned. Let the soldiers earn the Purple Hearts. Let women die old, white-crowned, with human hearts.”
—Ursula K. Le Guin (b. 1929)

“And open field, through which the pathway wound,
And homeward led my steps. Magnificent
The morning rose, in memorable pomp,
Glorious as e’er I had beheld—in front,
The sea lay laughing at a distance; near,
The solid mountains shone, bright as the clouds,
Grain-tinctured, drenched in empyrean light;”
—William Wordsworth (1770–1850)
