OBJECTIVE To investigate the role of CD147 gene on the proliferation and infiltration of a human monocytic leukemic cell line SHI-1. METHODS The expression of CD147 in SHI-1 cells was knockdowned by the lentiviral vector. The expressions of CD147, MMP-2 and MMP-9 were detected by semiquantitative RT-PCR. The protein of CD147 was detected by Western(More)

OBJECTIVE To investigate the TNF-alpha induced apoptosis of U937 cells, the expression, degradation and subcellular localization of IkappaB-alpha, and its degradation mechanism. METHOD Changes and subcellular loca-lization of IkappaB-alpha were observed by fluorescence microscopy, expression and degradation of IkappaB-alpha protein with(More)
A broad attention has been paid to the field ditches as the sewage interception channel for the agricultural nonpoint source pollution, however, rare studies have involved in the phosphorus migration and transformation between the ditch sediments and overlaying water, especially, from the ditch sediments to the water. The present paper aims to explore with(More)
