Table 1. Real-Time PCR results obtained from mRNA extracted from salivary glands, trachea and stomach showing differential expression of the Muc5b and Muc5ac in these tissues.

	Muc5ac	Muc5b
Stomach	19.06 (±4.8)	ND
Trachea	0.108 (±0.13)	3.541 (±1.8)
Salivary gland	ND	18.3 (±3.2)
ND: not detectable

The data shown are raw expression normalized to GAPDH and SDHA housekeeping genes.
