AbstractTo predict the efficacy of hormonal therapy at the individual‐level, immunohistochemical methods are used to analyze expression of classical molecular biomarkers such as estrogen receptor (ER), progesterone receptor (PgR), and HER2. However, the current diagnostic standard is not perfect for the individualization of diverse cases. Therefore, establishment of more accurate diagnostics is required. Previously, we established a novel method that enables analysis of ER transcriptional activation potential in clinical specimens using an adenovirus estrogen response element–green fluorescence protein (ERE‐GFP) assay system. Using this assay, we assessed the ERE transcriptional activity of 62 primary breast cancer samples. In 40% of samples, we observed that ER protein expression was not consistent with ERE activity. Comparison of ERE activity with clinicopathological information revealed that ERE activity was significantly correlated with the ER target gene, PgR, rather than ER in terms of both protein and mRNA expression. Moreover, subgrouping of Luminal A‐type breast cancer samples according to ERE activity revealed that ERα mRNA expression correlated with ER target gene mRNA expression in the high‐, but not the low‐, ERE‐activity group. On the other hand, the low‐ERE‐activity group showed significantly higher mRNA expression of the malignancy biomarker Ki67 in association with disease recurrence in 5% of patients. Thus, these data suggest that ER expression does not always correlate with ER transcriptional activity. Therefore, in addition to ER protein expression, determination of ERE activity as an ER functional marker will be helpful for analysis of a variety of diverse breast cancer cases and the subsequent course of treatment.

AbstractHydrogenation of 1,3‐butadiene and 1‐butyne over the Rh/chitosan catalyst in gaseous and liquid phases was investigated by using the NMR and parahydrogen‐induced polarization technique. The Rh/chitosan system was a very selective catalyst for the partial hydrogenation of 1,3‐butadiene and 1‐butyne to 1‐ and 2‐butenes. The catalyst demonstrated high activity in the hydrogenation of 1‐butyne after its activation in the hydrogenation of 1,3‐butadiene. Therefore, the Rh/chitosan catalyst was used for the catalytic removal of 1,3‐butadiene and 1‐butyne from gaseous butene streams. Moreover, the syn‐ and anti‐addition of the hydrogen molecule to substrates proceeded in a pairwise manner in the gas phase heterogeneous hydrogenation as was demonstrated by parahydrogen‐induced polarization. However, in the liquid phase hydrogenation of 1‐butyne, both hydrogen atoms from the same hydrogen molecule were added to 1‐butyne only through the syn‐addition route.

Published: October 2012

AbstractA bimodification synthesis method—“in situ oxidation at the interface (IOI) coupled with an ion exchange”—has been developed for the internal surface modification of mesoporous silicon oxide (MPS) templates. First, manganese oxide was formed at the internal surface of the MPS template through IOI. In the IOI method, high‐valent oxo‐anions of manganese (MnO4−) were used for the selective oxidation of poly(ethylene oxide) (PEO) groups of the Pluronic P123 (PEO20PPO70PEO20; PPO=poly(propylene oxide)) surfactant and they formed manganese oxide at the organic–inorganic (corona) interface. The oxide formation was restricted at the corona interface by a positively charged CTA+ (cetyltrimethylammonium) head group of the cationic surfactant CTABr. Then, the second modification of the MPS template was also performed by introducing promoter cations (Cs+, K+, or H+) through an ion exchange reaction between the cations and CTA+. The bimodified MPSMnX (X=Cs, K, or H) samples preserved the mesoporosity and high surface area of the MPS template. The bimodified MPSMnX samples were found to be more active, selective, and stable than the singly modified MPSMn sample for the gas‐phase oxidation of toluene.
