?-arbutin is biosynthesized by whole cell method with Xanthomona maltophilia BT-112.The conditions for cell biosynthesized ?-arbutin are investigated as follows:temperature,25℃;concentration of hydroquinone,30mmol/L;mol ratio of sucrose and hydroquinone,20∶1;time course of ?-arbutin biosynthesis,45 hours;rotational speed,160r/min;concentration of Xanthomona maltophilia BT-112,85g/L;concentration of K-2HPO-4-KH-2PO-4 buffer solution,25mmol/L;pH of K-2HPO-4-KH-2PO-4 buffer solution,8.0.Under the above optimal conditions,the maximum of molar conversion yield based on the amount of hydroquinone supplied reaches 86.7%.

AIM: To study the effect of wild-type p53 gene on the differentiation, apoptosis and expression of scavenger receptor CD36 in U937 cells. METHODS: Recombinant adenovirus vector with wild-type p53 gene was constructed and used to transfect U937 cells. With the expression of wild-type p53 gene following adenoviral infection, transfected U937 cells were largely promoted to differentiate into macrophages. RESUITS: Trypanblue-staining test demonstrated that the percentage of positive cells increased from (14.2±5.5)% to (64.6±9.2)% and nitroblue tetrazolium (NBT) reduction test reached similar results (6.3±1.8)% vs (49.7±12.6)%. Furthermore, CD36 mRNA was up-regulated as confirmed by RT-PCR. The increased expression level of CD 36 was also detected by flow cytometry analysis. CONCLUSION: These results suggest that wild-type p53 gene can affect U937 cells differentiation and apoptosis, up-regulate expression of scavenger receptor CD36. It may have a potential significance on atherogenesis.
