RESUMEN
Because the large number of people is suffering from asthma, and about half of them are not well controlled, new therapeutic approach and more effective medicines are therefore urgently needed. Recent studies have shown that bitter taste receptors (T2Rs) are expressed in various tissues, and T2Rs might be used as the new targets for asthma treatment since some bitter compounds show therapeutic potential for asthma therapies. In this study, the relationship between the development and exacerbation of asthma and bitter signal transduction was analyzed by establishing the asthma model in the C57BL/6 mice. The present results showed that the total number of white blood cells and the number of eosinophil, neutrophil, lymphocyte and macrophages in the bronchoalveolar lavage fluid (BALF) were significantly increased (P < 0. 05), accompanied with the up-regulation of Muc5ac gene expression (P< 0. 01) and asthma-like pathologically changes in mice lungs in OVA or OVA+SO
RESUMEN
Histone acetylation is one of the most important reactions of post-translational modification of histones, which plays an important role in the regulation of epigenetic processes. Histone deacetylase 2 as a member of type I histone deacetylases,involved in the catalytic regulation of histone and a variety of non-histone deacetylation,regulates a variety of life processes. This paper summarizes the basic structure of histone deacetylase 2 and the role of histone deacetylase 2 in various diseases,and provides a theoretical basis for conducting related studies.
