Fertility-preserving treatment outcome in endometrial cancer or atypical hyperplasia patients with polycystic ovary syndrome

ObjectiveThis study aimed to investigate the impact of polycystic ovary syndrome (PCOS) on fertility-sparing treatment in young patients with atypical endometrial hyperplasia (AEH) or endometrioid endometrial cancer (EEC).MethodsA total of 285 patients with EEC (n=76, FIGO stage IA, without myometrium invasion) or AEH (n=209) who received progestin-based fertility-sparing treatment were evaluated retrospectively. Among the 285 patients, 103 (36.1%), including 70 AEH cases and 33 EEC cases, were diagnosed with PCOS. General characteristics, cumulative 16- and 32-week complete response (CR) rate, pregnancy outcome and recurrence were compared between patients with or without PCOS.ResultsThe cumulative 16-week CR rate was lower in the PCOS group than in the non-PCOS group (18.4% vs. 33.8%, p=0.006). Patients with PCOS took longer treatment duration to achieve CR (7.0 months vs. 5.4 months, p=0.006) and shorter time to relapse after CR (9.6 months vs. 17.6 months, p=0.040) compared with non-PCOS group. After adjusting for patient age, body mass index, PCOS, homeostasis model assessment-insulin resistance index, and serum testosterone levels, we found that body mass index ≥25 kg/m² (HR=0.583; 95% CI=0.365–0.932; p=0.024) and PCOS (HR=0.545; 95% CI=0.324–0.917; p=0.022) were significantly correlated with lower 16-week CR rate.ConclusionPCOS was associated with lower 16-week CR rate, longer treatment duration and shorter recurrence interval in patients with AEH or EEC receiving fertility-preserving treatment.

Formosanin C-inhibited pulmonary metastasis through repression of matrix metalloproteinases on mouse lung adenocarcinoma

Formosanin C (FC) isolated from Rhizoma Paridis, showed pro-apoptosis and immunoregulation with antitumor activity in cultured cells and animal systems. However, there is no report about its anti-metastatic effect on cancer cells. This research used the wound healing and the migration assay to detect the anti-invasive effect of FC on LA795 cells. Through the gelatin zymography assay and immunofluorescence analysis, FC showed suppression of enzyme activity of MMP-2 and MMP-9, and protein expression of MMP-1, -2, -3, -9 and -14 excreted from LA795 cells. Finally, FC exhibited much more effective inhibition of tumor growth and pulmonary metastasis in T739 mice than cisplatin did. Overall, the strong inhibition of MMP expression by FC might provide a potential therapeutic modality for lung tumors.

Nutritional supplementation with transforming growth factor-beta inhibits intestinal adaptation after massive small bowel resection in a rat

Introduction  

Transforming growth factor beta (TGF-β) has been shown to affect epithelial cell differentiation and proliferation through epithelial-mesenchymal and epithelial-immune cell interaction. In the present study, we evaluated the effect of TGF-β2-enriched polymeric diet (Modulen) on enterocyte turnover in a rat model of short bowel syndrome (SBS).     

Histone deacetylase-related protein inhibits AES-mediated neuronal cell death by direct interaction

Histone deacetylase-related protein (HDRP), an alternatively spliced and truncated form of histone deacetylase-9 that lacks a C-terminal catalytic domain, protects neurons from death. In an effort to understand the mechanism by which HDRP mediates its neuroprotective effect, we screened for proteins in the brain that interact with HDRP by using a yeast two-hybrid assay. One of the HDRP-interacting proteins identified in this screen was amino enhancer of split (AES), a 197-amino acid protein belonging to the Groucho family. Interaction between HDRP and AES was verified by in vitro binding assays, coimmunoprecipitation, and colocalization studies. To investigate the significance of the HDRP-AES association to the regulation of neuronal survival, we used cultured cerebellar granule neurons, which undergo apoptosis when treated with low potassium (LK) medium. We found that in contrast to HDRP, whose expression is markedly reduced by LK treatment, AES expression was not appreciably altered. Forced expression of AES in healthy neurons results in cell death, an action that is blocked by the coexpression of HDRP. AES is a truncated version of larger Groucho-related proteins, one of which is transducin-like enhancer of split (TLE)-1. We found that the expression of TLE1 is reduced in LK-treated neurons and the forced expression of TLE1 blocks LK-induced neuronal death as well as death induced by AES. Our results show that AES has apoptotic activity in neurons and suggest that neuroprotection by HDRP is mediated by the inhibition of this activity through direct interaction.
