Formaldehyde Dehydrogenase - Role in Disease

Role in Disease

It has been shown that GSNOR may have an important role in respiratory diseases such as asthma. GSNOR expression has been inversely correlated with s-nitrosothiol (SNO) levels in the alveolar lining fluid in the lung and with responsiveness to methacholine challenge in patients with mild asthma compared to normal subjects. Furthermore, there are lowered SNOs in tracheal irrigations in asthmatic children with respiratory failure in comparison to normal children undergoing elective surgery and NO species are elevated in asthma patients when exposed to antigen.

Assessing the gene expression of the ADHs in nonalcoholic steatohepatitis (NASH) patients has shown elevated levels of all ADHs, but primarily ADH1 and ADH4 (up to 40-fold increased). ADH5 showed an ~4-fold increase in gene expression.

Famous quotes containing the words role in and/or role:

    Language makes it possible for a child to incorporate his parents’ verbal prohibitions, to make them part of himself....We don’t speak of a conscience yet in the child who is just acquiring language, but we can see very clearly how language plays an indispensable role in the formation of conscience. In fact, the moral achievement of man, the whole complex of factors that go into the organization of conscience is very largely based upon language.
    Selma H. Fraiberg (20th century)

    The real test of a man is not how well he plays the role he has invented for himself, but how well he plays the role that destiny assigned to him.
    Jan Patocka (1907–1977)
