OBJECTIVE To explore the expression and significance of serum programmed cell death 5 (PDCD5) in patients with bronchial asthma. METHODS From June to December 2011, a total of 40 adults with bronchial asthma treated in Peking University Third Hospital were enrolled. Among them, the categories were acute phase (n = 12), chronic phase (n = 14) and remission phase (n = 14). Fifteen healthy adults were selected into the control group. The percentages of peripheral blood neutrophils and eosinophils were collected and detected for each patient. Serum PDCD5 was detected with enzyme-linked immunosorbent assay (ELISA) and asthma control test (ACT) questionnaire filled in. The relevant pulmonary functional indicators were analyzed with a pulmonary spirometer. Two-independent sample t-test and Pearson's correlation analysis were used for statistical analysis. RESULTS No significant difference was found between two groups with regards to the percentages of peripheral blood eosinophils and neutrophils (all P > 0.05). Serum PDCD5 was significantly higher in the patient group ((47.7 ± 29.6) vs (19.3 ± 9.8) µg/L, P < 0.05). Patients of chronic and acute phases showed a significant higher expression in PDCD5 than the remission phase ((55.2 ± 24.5) & (68.5 ± 22.1) vs (16.0 ± 7.9) µg/L, both P < 0.05). Serum PDCD5 of asthmatics showed a negative correlation with FEV(1)%, FEV(1)/FVC ratio and ACT scores (r = -0.539 to -0.798, all P < 0.05). CONCLUSIONS PDCD5 participates in the inflammatory process of asthmatic airway. Its abnormal expression may be associated with the uncontrolled state of asthmatics. It may serve as an indicator of assessing the levels of asthma control or a target for the treatment of asthma.

D008297 Male Males
D008875 Middle Aged An adult aged 45 - 64 years. Middle Age
D009363 Neoplasm Proteins Proteins whose abnormal expression (gain or loss) are associated with the development, growth, or progression of NEOPLASMS. Some neoplasm proteins are tumor antigens (ANTIGENS, NEOPLASM), i.e. they induce an immune reaction to their tumor. Many neoplasm proteins have been characterized and are used as tumor markers (BIOMARKERS, TUMOR) when they are detectable in cells and body fluids as monitors for the presence or growth of tumors. Abnormal expression of ONCOGENE PROTEINS is involved in neoplastic transformation, whereas the loss of expression of TUMOR SUPPRESSOR PROTEINS is involved with the loss of growth control and progression of the neoplasm. Proteins, Neoplasm
