Treatment of cells with carcinogen Benzo[a]pyrene (B[a]P) allows cells to evade G1 arrest and induces cells abnormal proliferation. However, the mechanisms of its action at cellular level are not well understood. To address this question, normal human embryo lung diploid fibroblasts (HELF) were selected in the present study. We found that exposure of cells(More)
A glucan, GBW, was isolated from the alkaline aqueous extract of Glycyrrhiza uralensis Fisch. Its mean molecular weight was estimated to be 4 x 10(3). TLC, methylation analysis, periodate oxidation, Smith degradation, partial acid hydrolysis, KI--I2 reaction, IR and 13CNMR showed that GBW is a (1----4) linked alpha-D-glucan (6).
