OBJECTIVETo observe the effects of deguelin on the apoptosis and proliferation of human esophageal cancer cell Ec-109, and to explore its possible mechanisms.

METHODSHuman esophageal cancer cells Ec-109 were in vitro cultured. They were divided into the blank control group, and 5, 10, 20, and 40 nmol/L deguelin groups. The inhibition on the proliferation was detected at 24, 48, and 72 h using CCK-8 assay. The early apoptosis rate at 24 h was detected by flow cytometry. The expressions of apoptosis-related proteins Bcl-2 and Bax were detected at 24 and 48 h respectively.

RESULTSCompared with the blank control group at the same point, the growth inhibition rate in all deguelin groups increased at 24, 48, and 72 h, showing statistical difference (P <0.05). The early apoptosis rate was 4.37% +/- 0.35%, 6.71% +/-0.14%, 15.62% +/- 0.21%, and 19.78% +/- 0.15% in 5, 10, 20, and 40 nmol/L deguelin groups, respectively, showing statistical difference when compared with that of the blank control group (1.10% +/- 0.08%, P < 0.05). Compared with the blank control group, Bcl-2 protein expression obviously decreased, and Bax protein expression obviously increased in 10, 20, and 40 nmol/L deguelin groups, showing statistical difference (P <0.05). The aforesaid indices were in time- and dose-dependent manners.

CONCLUSIONDeguelin showed obvious effects on inhibiting the proliferation of Ec-109 cells and promoting their apoptosis, which was correlated with up-regulating Bax protein expression and down-regulating Bcl-2 protein expression.

Macrophages are involved in many important biological processes and membrane proteins are the key effector molecules for their functions. However, membrane proteins are difficult to analyze by 2-DE based method because of their intrinsic tendency to self-aggregate during the first dimension separation (IEF). To circumvent the obstacle hampering membrane protein analysis, we combined one-dimensional SDS-PAGE with capillary liquid chromatography-tandem mass spectrometry (LC-MS/MS). Using this technique, we identified 458 GO annotated membrane proteins with extremely high confidence, including most known markers of peritoneal macrophages (e.g., CD11b, F4/80, CD14, CD18, CD86, CD44, CD16 and Toll-like receptor). Thirteen other CD antigens and 18 Ras-related small GTPase were also identified. In addition to those known macrophage membrane proteins, a significant number of novel proteins have also been identified. This research provides a valuable data set of macrophage membrane proteins, thus allowing for more comprehensive study of membrane proteins and a better understanding of the function mechanisms of macrophages in many biological processes.

Background Researches showed that triterpenoids,with a similar structure to lanosterol,has therapeutical effect on many systemic diseases,and lanosterol was determined to have a therapeutical effect on cataract recently.However,how the lanosterol plays effects on other eye diseases is still unelucidated.Understanding the distribution of lanosterol in ocular tissue is helpful for us to elucidate the relationship of lanosterol with eye diseases.Objective This study attempted to investigate the distribution of lanosterol synthase (LSS) and lanosterol in cornea,lens and retina tissue of rats and offer a basis for the targeting treatment of eye diseases.Methods Fifteen SPF male SD rats were sacrificed by excessive anesthesia to obtain the eyeballs.The relative expressions of LSS protein and gene in the cornea,lens and retina tissue of the rats were detected by Western blot and reverse transcription (RT)-PCR,respectively.Immunofluorescence staining technology was used to locate the distribution of LSS in cornea,lens and retina tissue.The contents of lanosterol in the cornea,lens and retina tissue were analyzed by liquid chromatograph mass spectrometer (LC-MS).Results No LSS protein and mRNA was expressed in the retinal tissue in normal rats.The mean relative expression of LSS protein in the lens and cornea was 0.43±0.05 and 0.25±0.03,respectively,showing a significant difference between them (t =-5.35,P＜ 0.01).The relative expression of LSS mRNA was 0.51 ±0.04 and 0.29 ±0.02 in the lens and cornea,respectively,with a stronger expression in the lens in comparison with the cornea (t =-8.34,P＜0.01).Immunofluorescence staining showed that LSS primarily located in corneal epithelial layer,stromal layer and endothelial layer as well as lens epithelial cells and shallow cortex layer and hardly expressed in retina,and no co-expression of LSS with the neuron marked by NeuN and the Müller cell marked by glutamine synthetase (GS) in retinal tissue.LC-MS analysis revealed that the contents of lanosterol in lens and cornea was (24.37 ±2.91) ng/mg and (5.31 ±0.58) ng/mg,respectively,with a significant difference between them (t =-11.13,P＜0.01).Conclusions LSS and lanosterol extensively distribute in cornea and lens of normal rats,but not in retina tissue.These results offer new strategies for the target treatment of relevant eye diseases.

The aim of this study is to investigate the anti-inflammatory effect of the adenosine derivative N6-(3-hydroxylaniline) adenosine (WS070117M1) on cigarette smoke plus LPS (lipopolysaccharide)-induced chronic obstructive pulmonary disease (COPD) in mice and its mechanism. COPD model was established by exposing male BALB/c mice to cigarette smoke and challenged with LPS inhalation. Supernatants of bronchoalveolar lavage fluid (BALF) were harvested and IL-1β, IL-6, IL-8 and TGF-β1 levels were measured by ELISA (enzyme-linked immunesorbent assay). The number of total white blood cells and neutrophils in bronchoalveolar lavage fluid was counted separately. Lung tissue was stained with Mayer 's hematoxylin and eosin for histopathologic examination. pAMPKa protein expression and distribution of lung tissue were analyzed by immunohistochemistry method. In vitro, levels of AMPKα phosphorylation in phorbol-12- myristate-13-acetate (PMA) differentiated THP-1 cells was detected by immunohistochemistry, IL-8 level in supernatants of cigarette smoke condensate stimulating PMA differentiated THP-1 cells was measured by ELISA. The results showed that WS070117M1 treatment significantly activated AMPKa in the lung tissue. It also resulted in down regulation of IL-1β, IL-6, IL-8 and TGF-β1 levels in bronchoalveolar lavage fluid and IL-8 level in cigarette smoke condensate stimulating PMA differentiated THP-1 cells. In addition, WS070117M1 could inhibit the recruitment of total white blood cells and neutrophils. These results suggest that WS070117M1 may alleviate the airway inflammation by activating AMPK in the lung tissue.
