OBJECTIVETo study gene expression profiling in human type I and II endometrial carcinoma.

METHODSSix Affymetrix human genome genechips were utilized to investigate the differences in gene expression profiles between type I and II endometrial carcinoma with bioinformatic analysis.

RESULTSMany genes were highly expressed in estrogen-dependent endometrial carcinoma, and some of them were involved in the metabolism and conversion of estrogen, while some others in estrogen regulation. CYP2C9, for instance, was involved in the conversion of estrogen sulfate to 16-hydroxy sulfate metabolite, DDC in estrogen-dependent pathogenesis of endometrial carcinoma possibly by DDC interaction with AR to enhance steroid receptor transcription.

CONCLUSIONHigh expression of these genes in estrogen-dependent endometrial carcinoma may provide insights into their roles in the pathogenesis and prognosis of this malignancy.

OBJECTIVETo investigate the protective mechanism of geniposide, baicalin and berberine on hypoxia and reoxygenation injury in cultured rat cerebral microvascular endothelial cells.

METHODTo establish a model of hypoxia four hours and reoxygenation twelve hours injury in rat cerebral microvascular endothelial cells in vitro. The injured cells were treated with geniposide (0. 128, 0.064, 0.032 micromol mL(-1), baicalin (0.028, 0.014, 0.007 micromol mL(- 1)) and berberine (0.024, 0.012, 0.006 micromol mL(-1)). The expression of p65 subunit of NF-kappaB was detected by immunocytochemical assay and techniques of image quantitative analysis. The protein expression of NF-kappaB was calculated with the mean optical density and mean area. The nuclear translocation of NF-kappaB was calculated with the percentage of positive cells and ratios of light transmittance of cytoplasm and cell nucleus.

RESULTCompared with the normal group, both the protein expression and the nuclear translocation of NF-kappaB of model group were significant increased (P <0.01). Compared with the model group, the mean optical density of all treated groups was decreased ,but these was no significant difference between them. As compared with model group, the mean area of all treated groups was significant decreased (P < 0.01). The percentage of nuclear translocation of all treated groups is not only lower than that of the model group but higher than that of the normal group (P <0.01). Compared with the model group, the ratios of light transmittance of cytoplasm and cell nucleus of all treated groups was significantly elevated (P <0.01).

CONCLUSIONThe results suggesed that geniposide, baicalin and berberine could protect hypoxia/reoxygenation injuried rat cerebral microvascular endothelial cells injury. One of the mechanism may lie in inhibiting both the protein expression and the nuclear translocation of NF-kappaB.

OBJECTIVETo investigate the protective mechanism of geniposide, baicalin and berberine on hypoxia and reoxygenation injury in cultured rat cerebral microvascular endothelial cells.

METHODA model of four hours hypoxia and twelve hours reoxygenation injury in rat cerebral microvascular endothelial cells in vitro was established. The injured cells were treated with geniposide (0.128, 0.064, 0.032 mmol x L(-1)), baicalin (0.028, 0.014, 0.007 mmol L(-1)) and berberine (0.024, 0.012, 0.006 mmol L(-1)), respectively. The immunocytochemical method and techniques of image quantitative analysis were used to detect the mean optical density and mean area in order to match the protein expression of VCAM-1. The method of RT-PCR was adopted to observe and match the mRNA expression of VCAM-1.

RESULTAs compared with the normal group, the mean optical density, the mean area and the mRNA expression of VCAM-1 of model group were significant increased (P < 0.01, P < 0.01, P < 0.01). As compared with the model group, both the mean optical density and the mean area of all treated groups were decreased, and there was significant difference between them (P < 0.01, P < 0.01). As compared with normal group, the mean optical density of baicalin (0.007 mmol x L(-1)) and berberine (0.012, 0.006 mmol x L(-1)) were significant decreased (P < 0.05, P < 0.01, P < 0.01), but there was no significant difference between the other groups and the normal group. As compared with normal group, the mean area of baicalin (0.0014 mmol x L(-1)) was significant decreased (P < 0.05), but there was significant difference between the other groups and the normal group. The mRNA expression of all treated groups was not only lower than that of the model group but also higher than that of the normal group (P < 0.05, P < 0.05).

CONCLUSIONThe results suggest that geniposide, baicalin and berberine, which are effective compositions of huanglian jiedu decoting, can protect hypoxia-reoxygenation injuried rat cerebral microvascular endothelial cells. One of the protected mechanisms is that they can inhibit the expression of VCAM-1.
