MED19 is a member of the Mediator that plays a key role in the activation and repression of signal transduction or the regulation of transcription in carcinomas. To tested the functional role of MED19 in human prostate cancer, we downregulated MED19 expression in prostate cancer cells (PC-3 and DU145) by lentivirus- mediated short hairpin (shRNA), and analyzed the effect of inhibition of MED19 on prostate cancer cell proliferation and tumorigenesis. The in vitro prostate cancer cell proliferation, colony formation, and in vivo tumor growth in nude mice xenografts was significantly reduced after the downregulation of MED19. Knock- down of MED19 caused S-phase arrest and induced apoptosis via modulation of Bid and Caspase 7. It was suggested that MED19 serves as a novel proliferation regulator that promotes growth of prostate cancer cells. [BMB reports 2011; 44(8): 547-552]

A series of 7-alkoxy-4,5-dihydro-[1,2,4]oxadiazolo[4,3-a]quinolin-1-ones was synthesized and theirnegative inotropic effects were evaluated by measuring theleft atrium stroke volume in isolated rabbit heart preparations. All compounds moderated the cardiac workload bydecreasing heart rate and contractility (inotropic effects). Among them, compound 6 was found to be best potent witha -28.89 ± 1.91 % decrease in the stroke volume at aconcentration of 3 9 10-5 M in our in vitro study.

Two new (1 and 3) and two known diarylheptanoids(2 and 4), along with two tetralones (5 and 6), onenaphthoquinone (7), four phenylpropanoids (8–11), andone phenol (12) were isolated from the leaves of Juglansmandshurica. Their structures were elucidated on the basisof spectral and chemical data. Compounds 2 and 10 arefirstly isolated from this plant and 8 and 12 were isolatedfrom the Juglans genus for the first time. Among thesecompounds, only 7 exhibited moderate cytotoxicitiesagainst cultured MGC-803, A549, K562, and HeLa tumorcell lines with IC50 values of 25.90, 28.60, 39.06,44.90 lM, respectively.

The relationship between the X-ray repair cross-complementing group 3 (XRCC3) Thr241Met polymorphism and gliomas remains inclusive or controversial. For better understanding of the effect of XRCC3 Thr241Met polymorphism on glioma risk, a meta-analysis was performed. All eligible studies were identified through a search of PubMed, Elsevier Science Direct, Excerpta Medica Database (Embase) and Chinese Biomedical Literature Database (CBM) before May 2013. The association between the XRCC3 Thr241Met polymorphism and gliomas risk was conducted by odds ratios (ORs) and 95% confidence intervals (95% CIs). A total of nine case-control studies including 3,533 cases and 4,696 controls were eventually collected. Overall, we found that XRCC3 Thr241Met polymorphism was significantly associated with the risk of gliomas (T vs. C: OR=1.10, 95%CI=1.01-1.20, P=0.034; TT vs. CC: OR=1.30, 95%CI=1.03-1.65, P=0.027; TT vs. TC/CC: OR=1.29, 95%CI=1.01-1.64, P=0.039). In the subgroup analysis based on ethnicity, the significant association was found in Asian under four models (T vs. C: OR=1.17, 95%CI=1.07-1.28, P=0.00; TT vs. CC: OR=1.79, 95%CI=1.36-2.36, P=0.00; TT vs. TC/CC: OR=1.75, 95%CI=1.32-2.32, P=0.00; TT/TC vs. CC: OR=1.11,95% CI=1.02-1.20). This meta-analysis suggested that the XRCC3 Thr241Met polymorphism is a risk factor for gliomas, especially for Asians. Considering the limited sample size and ethnicities included in the meta-analysis, further large scale and well-designed studies are needed to confirm our results.

Two new anthraquinones, melrubiellin C (1) andmelrubiellin D (2), were isolated from the aerial parts of Melandriumfirmum Rohrbach, together with eight known compounds(3–10). The structures of these compounds wereelucidated using 1Dand 2DNMR(COSY,HMQC,HMBCandNOESY) experiments. All isolated compounds were tested fortheir cytotoxicity against NCI-H460, Hep G2, MKN-28 andA-549 cells.Of these 10 compounds,1 and 2 exhibitedmoderatecytotoxicity with IC50 values ranging from 9.54 to 32.41 lM.

The present study was designed to isolate and characterize novel chemical constituents of the stem bark of Juglans mandshurica Maxim. (Juglandaceae).The chemical constituents were isolated and purified by various chromatographic techniques. The structures of the compounds were elucidated on the basis of spectral data (1D and 2D NMR, HR-ESI-MS, CD, UV, and IR) and by the comparisons of spectroscopic data with the reported values in the literatures. Two long chain polyunsaturated fatty acids (1 and 2) were obtained and identified as (S)-(8E, 10E)-12-hydroxy-7-oxo-8, 10-octadecadienoic acid (1) and (S)-(8E, 10E)-12-hydroxy-7-oxo-8,10-octadecadienoic acid methyl ester (2). To the best of our knowledge, this is the first report on the isolation and structural elucidation of the two new conjugated ketonic fatty acids from this genus.
