Abstract
In the present study, a novel dimer, SM1044, selected from a series of dihydroartemisinin (DHA) derivatives containing nitrogen atoms comprising simple aliphatic amine linkers, showed strong growth inhibition in six types of human endometrial cancer (EC) cells, with half maximal inhibitory concentration (IC50) and 95% confidence interval (CI) < 3.6 (1.16~11.23) μM. SM1044 evoked apoptosis and activated caspase-3, -8 and -9 in a concentration- and time-dependent manner, and these effects were manifested early in RL95-2 compared to KLE cells, possibly correlated with the induction of intracellular ONOO-. Catalase and uric acid attenuated the growth inhibitory effects of SM1044 on EC cells, but sodium pyruvate did not. In vivo, the average xenograft tumour growth inhibition rates ranged from 35.8% to 49.9%, respectively, after 2.5 and 5.0 mg/kg SM1044 intraperitoneal treatment, and no obvious behavioural and histopathological abnormalities were observed in SM1044-treated mice in this context. SM1044 predominantly accumulated in the uteri of mice after a single injection. SM1044 displayed efficacy as a tumour suppressor with distinct mechanism of action and unique tissue distribution, properties that distinguish it from other artemisinin analogues. Our findings provide a new clue for artemisinin analogue against cancer.

Abstract
Among a variety of phytocannabinoids, Δ9-tetrahydrocannabinol (THC) and cannabidiol (CBD) are the most promising therapeutic compounds. Besides the well-known palliative effects in cancer patients, cannabinoids have been shown to inhibit in vitro growth of tumor cells. Likewise, the major endocannabinoids (eCBs), anandamide (AEA) and 2-arachidonoylglycerol (2-AG), induce tumor cell death. The purpose of the present study was to characterize cannabinoid elements and evaluate the effect of cannabinoids in endometrial cancer cell viability. The presence of cannabinoid receptors, transient receptor potential vanilloid 1 (TRPV1), and endocannabinoid-metabolizing enzymes were determined by qRT-PCR and Western blot. We also examined the effects and the underlying mechanisms induced by eCBs and phytocannabinoids in endometrial cancer cell viability. Besides TRPV1, both EC cell lines express all the constituents of the endocannabinoid system. We observed that at concentrations higher than 5 μM, eCBs and CBD induced a significant reduction in cell viability in both Ishikawa and Hec50co cells, whereas THC did not cause any effect. In Ishikawa cells, contrary to Hec50co, treatment with AEA and CBD resulted in an increase in the levels of activated caspase -3/-7, in cleaved PARP, and in reactive oxygen species generation, confirming that the reduction in cell viability observed in the MTT assay was caused by the activation of the apoptotic pathway. Finally, these effects were dependent on TRPV1 activation and intracellular calcium levels. These data indicate that cannabinoids modulate endometrial cancer cell death. Selective targeting of TPRV1 by AEA, CBD, or other stable analogues may be an attractive research area for the treatment of estrogen-dependent endometrial carcinoma. Our data further support the evaluation of CBD and CBD-rich extracts for the potential treatment of endometrial cancer, particularly, that has become non-responsive to common therapies.

Abstract
Transmembrane mucins (TMs) are restricted to the apical surface of normal epithelia. In cancer, TMs not only are over-expressed, but also lose polarized distribution. MUC16/CA125 is a high molecular weight TM carrying the CA125 epitope, a well-known molecular marker for human cancers. MUC16 mRNA and protein expression was mildly stimulated by low concentrations of TNFα (2.5 ng/ml) or IFNγ (20 IU/ml) when used alone; however, combined treatment with both cytokines resulted in a moderate (3-fold or less) to large (> 10-fold) stimulation of MUC16 mRNA and protein expression in a variety of cancer cell types indicating that this may be a general response. Human cancer tissue microarray analysis indicated that MUC16 expression directly correlates with TNFα and IFNγ staining intensities in certain cancers. We show that NFκB is an important mediator of cytokine stimulation of MUC16 since siRNA-mediated knockdown of NFκB/p65 greatly reduced cytokine responsiveness. Finally, we demonstrate that the 250 bp proximal promoter region of MUC16 contains an NFκB binding site that accounts for a large portion of the TNFα response. Developing methods to manipulate MUC16 expression could provide new approaches to treating cancers whose growth or metastasis is characterized by elevated levels of TMs, including MUC16.

Abstract
A role for activins in regulating cellular transformation is suggested by the alpha-inhibin knockout mouse in which development of gonadal tumors is associated with elevated activin levels. It was the purpose of the current study to determine whether activin had similar actions on endometrial cell lines, specifically on a well differentiated estrogen-responsive endometrial adenocarcinoma cell line (ISH) and estrogen-unresponsive cells (HEC-50) obtained from a poorly differentiated endometrial adenocarcinoma. Activin was secreted by both adenocarcinoma cell lines. Using reverse transcription-PCR, messenger RNA type I and type II activin receptor subtypes were detected in both cell lines: expression of IB and IIB was approximately three- to fourfold greater in ISH cells than in HEC-50 cells, while activin receptor IA and IIA messenger RNA levels were approximately equal in both cell lines. Activin treatment (30-300 ng/ml) caused a dose- and time-dependent inhibition of ISH cells proliferation and resulted in a significant decrease in Bcl-2 protein and mRNA levels. No difference was observed in Bax expression. There was no significant effect of activin when the cultures of ISH cells were exposed to 17beta-estradiol. In contrast, activin showed a weak, but significant, mitogenic effect on HEC-50 cells without modifications in Bax and Bcl-2 mRNA and protein levels. The results demonstrate that activin is a regulator of endometrial cancer cell growth. 17beta-Estradiol may promote resistance of estrogen-responsive endometrial cancer cells to the growth-retarding effects of activin and one of the mechanisms might be a down-regulation of the activin receptors.

Abstract
The effects of the transforming growth factor-beta 1 (TGF-beta 1) and epidermal growth factor (EGF) on the growth of cells from 2 endometrial cancer lines, Ishikawa and HEC-50 were evaluated by measuring rates of DNA synthesis and changes in cell numbers during culture. EGF at 17 and 1.7 nM concentrations consistently enhanced HEC-50 cell proliferation. TGF-beta 1 inhibited Ishikawa cell proliferation but, unexpectedly for epithelium-derived cells, stimulated HEC-50 cell growth. This effect is of interest as it indicates that endometrial cells can acquire an altered responsiveness to a growth inhibitor during the process of malignant transformation. Northern blot analyses showed expression of TGF-alpha, TGF-beta 1 and EGF receptors mRNA in both cell lines. Neither estradiol (E2) nor 4-hydroxytamoxifen (OHTam) affected mRNA levels for either TGF-alpha or TGF-beta in HEC-50 cells, a line unresponsive to E2 for proliferation. In Ishikawa cells, previously shown to respond to both E2 and OHTam by increasing proliferation rates, E2 increased TGF-alpha mRNA and reduced TGF-beta mRNA levels. OHTam lowered the levels of both mRNA species, although the effect was greater on TGF-beta than TGF-alpha mRNA. These data are consistent with, but do not prove, the existence of a possible autocrine regulation by TGF-alpha and TGF-beta of human cancer cell proliferation, which might be under E2 influence in Ishikawa cells.

Abstract
A simple, rapid approach to the study of conversion rates and metabolic patterns of the steroids testosterone and estradiol is presented. It includes an optimized isocratic high-performance liquid chromatographic procedure in the reversed-phase mode and radioactive on-line detection. The purpose was to estimate the activity of key enzymes of steroid pathways, such as 17 beta-hydroxysteroid dehydrogenase and 5 alpha-reductase, in in vivo conditions. Using this system, we obtained good efficiency and linearity of radio detection, under continuous flow conditions. Sensitivity limits were of the order of 50 and 70 cpm for [3H]estradiol and [14C]estrone, respectively, even though the efficiency was quite dissimilar (17.3% versus 56.2%). The applicability of this approach to studies of steroid metabolic pathways in growing cancer cells in culture is illustrated with examples of the conversion rates of both testosterone and estradiol. The high reproducibility (coefficients of variation of 2.7 and 5.1% for 3H and 14C, respectively) and good extraction efficiency (ranging from 86 to 94%) indicate the feasibility and reliability of this approach.

Abstract
Double labelling and Western blot techniques were used to demonstrate phosphorylation of estradiol receptor. Cells in monolayer culture were incubated with [32P]orthophosphate for 18 h followed by covalent whole cell labelling of the estradiol receptor with tritiated tamoxifen aziridine [( 3H]TA). Labelled receptor was precipitated with the monoclonal antibodies H222 or JS 34/32, coupled to protein A-Sepharose, and purified by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE), or transferred to nitrocellulose paper. Receptor protein was detected on the Western blot with the monoclonal antibody H222 and rabbit anti-rat peroxidase conjugate. Phosphorylated receptor was visualized by autoradiography. Tritium and 32P activities were monitored in the gels. Two phosphorylated forms of the receptor (molecular weights 67 and 50 kDa) have been detected in MCF-7 cells. Estradiol treatment of the cells was found to increase phosphorylation of the receptor. In estradiol-treated cells both phosphorylated receptor forms were present mainly in the nuclear extract. Both forms bound [3H]TA as evidence by SDS-PAGE. [3H]TA binding was abolished by excess non-radioactive estradiol. In addition two phosphorylated proteins of approximately 120 and 90 kDa were regularly coprecipitated with receptor in cytosol. These proteins did not bind [3H]TA. The 90 kDa phosphorylated protein was identified as a heat shock protein (hsp-90).
