"When HBEC lines were exposed to 100 nmol/L nicotine and then RNA was harvested at 72 and 144 h, a significant increase in the expression levels of CHRNA1, CHRNA5, and CHRNA7 were found at 72 h, with return to baseline levels of expression upon nicotine removal (Fig. 3 ). No significant increase or decrease was found in the levels of expression of other nAChR subunit genes analyzed." . . "Selventa" . . . . "2014-07-03T14:33:10.631+02:00"^^ . . .
