Results Compared with the asthma group, the count of EOS and the levels of GM-CSF increased (P

Objective To study the expression of estrogen receptor beta in the lung tissue of mice treaded with B[a]p alone or combined with estrogen (17 ?-estradiol, E2) in female Kunming strain mice and to explore the effect of estrogen in the lung cancer of mice induced by benzo[a]pyrene (B[a]P). Methods One hundred and twenty-five female Kunming mice were randomly divided into 5 groups: normal control group was group 1 ;group 2 was treated with subcutaneous injection of estrogen ( 900 ?g/kg); group 3 was given B[a]P(75 ?mol/kg) by gavage;the last two groups were given the same dosage of B[a]P (75 ?mol/kg)plus two different dosage of estrogen: 900 ?g/kg and 300 ?g/kg. After 8 weeks,there was a recovery period of 8 weeks. Then, the lung tissue was obtained by surgical resection. The expression of estrogen receptor-? gene and estrogen receptor-? protein of the lung tissue was detected by real-time PCR and Western blotting technology respectively. Results The expression of estrogen receptor-? protein and estrogen receptor-? gene in the B[a]P group and the B[a]P plus low dosage estrogen group was significantly higher than the normal group (P

Flocculent gene FLO1 and its truncated form FLO1c with complete deletion of repeat unit C were expressed in a non-flocculent industrial strain Saccharomyces cerevisiae CE6 to generate recombinant flocculent strains 6-AF1 and 6-AF1c respectively. Both strains of 6-AF1 and 6-AF1c displayed strong flocculation and better cell growth than the control strain CE6-V carrying the empty vector under acetic acid stress. Moreover, the flocculent strains converted glucose to ethanol at much higher rates than the control strain CE6-V under acetic acid stress. In the presence of 0.6% (V/V) acetic acid, the average ethanol production rates of 6-AF1 and 6-AF1c were 1.56 and 1.62 times of that of strain CE6-V, while the ethanol production rates of 6-AF1 and 6-AF1c were 1.21 and 1.78 times of that of strain CE6-V under 1.0% acetic acid stress. Results in this study indicate that acetic acid tolerance and fermentation performance of industrial S. cerevisiae under acetic acid stress can be improved largely by flocculation endowed by expression of flocculent genes, especially FLO1c.
