Eighth Circuit Bungles Bundled Discounts: The Court Avoids Resolving Bundled Discounts Note
In Southeast Missouri Hospital v. C.R. Bard, Inc., the Eighth Circuit passed on an opportunity to choose a bundled discount test and instead focused on the proper market for the products at issue. This Note first explores the bundled discounts and contracts at issue in the instant decision. It then provides a detailed explanation of bundled discounts and the various tests proposed for them, as well as an explanation of the Eighth Circuit’s precedent concerning bundled discounts. The Note concludes by analyzing the instant decision and discussing why the court should have addressed bundled discounts in its opinion and the consequences of its failure to do so

EZH2 Depletion Blocks the Proliferation of Colon Cancer Cells
The Enhancer of Zeste 2 (EZH2) protein has been reported to stimulate cell growth in some cancers and is therefore considered to represent an interesting new target for therapeutic intervention. Here, we investigated a possible role of EZH2 for the growth control of colon cancer cells. RNA interference (RNAi)-mediated intracellular EZH2 depletion led to cell cycle arrest of colon carcinoma cells at the G1/S transition. This was associated with a reduction of cell numbers upon transient transfection of synthetic EZH2-targeting siRNAs and with inhibition of their colony formation capacity upon stable expression of vector-borne siRNAs. We furthermore tested whether EZH2 may repress the growth-inhibitory p27 gene, as reported for pancreatic cancer. However, expression analyses of colon cancer cell lines and colon cancer biopsies did not reveal a consistent correlation between EZH2 and p27 levels. Moreover, EZH2 depletion did not re-induce p27 expression in colon cancer cells, indicating that p27 repression by EZH2 may be cell- or tissue-specific. Whole genome transcriptome analyses identified cellular genes affected by EZH2 depletion in colon cancer cell lines. They included several cancer-associated genes linked to cellular proliferation or invasion, such as Dag1, MageD1, SDC1, Timp2, and Tob1. In conclusion, our results demonstrate that EZH2 depletion blocks the growth of colon cancer cells. These findings might provide benefits for the treatment of colon cancer
