WebSep 1, 2002 · Peripheral oscillators in flies (e.g. antennal clock cells and Malpighian tubules) can also maintain robust (>7 day) rhythms in cell culture, which suggests that fly peripheral oscillators depend less on the sLN v s than do their mammalian counterparts on the SCN(Emery et al., 1997;Giebultowicz and Hege, 1997;Plautz et al., 1997). WebIntroduction “Circadian” is a Latin word that means “about a day”. 1 Living organisms on earth have evolved with an endogenous timing system, specifically the circadian clock. 1–3 Current research has demonstrated that numerous vital physiological processes that occur in mammals in vivo, such as sleeping and waking, hormone secretion, and immune …
