Chiral complexes formed by phosphoramidites such as (Sa,R,R)-9 and Cu(OTf)2 are excellent catalysts for the general 1,3-dipolar cycloaddition between azomethine ylides and nitroalkenes affording the corresponding tetrasubstituted proline esters mainly as exo-cycloadducts in high er at room temperature. The exo-cycloadducts can be obtained in enantiomerically pure form just after simple ...

Hepatocellular carcinoma (HCC) is a highly invasive type of cancer. Metastasis is the leading cause of mortality of advanced HCC patients. In the metastasis cascade, cancer cells undergo epithelial-mesenchymal transition resulting in the loss of cell‑to‑cell adhesion, migration and invasion into the stroma. Loss of E-cadherin expression is a key ...

Regulated degradation plays a major role in determining the levels of both non-coding (miRNA) and coding (mRNA) transcripts. Thus, insights into the factors and pathways that influence this process have broad, interdisciplinary implications. New findings by Malecki et al (2013), Lubas et al (2013), and Chang et al (2013) identify ...

Epidermal growth factor receptor (EGFR) is a receptor tyrosine kinase (RTK) that controls cell proliferation, growth, survival, metabolism, and migration by activating the PI3K (phosphatidylinositol 3-kinase)-AKT and ERK (extracellular signal-regulated kinase)-RSK (ribosomal S6 kinase) pathways. EGFR signaling to these pathways is temporally and spatially regulated. Endocytic trafficking controls the access ...

Multidisciplinary team meetings (MDTs), also known as tumour boards or multidisciplinary case conferences, are an integral component of contemporary cancer care. There are logistical problems with setting up and maintaining participation in these meetings. An ill-defined concept, the virtual MDT (vMDT), has arisen in response to these difficulties. We have, ...

Turnover of mRNA in the cytoplasm of human cells is thought to be redundantly conducted by the monomeric 5'-3' exoribonuclease hXRN1 and the 3'-5' exoribonucleolytic RNA exosome complex. However, in addition to the exosome-associated 3'-5' exonucleases hDIS3 and hDIS3L, the human genome encodes another RNase II/R domain protein-hDIS3L2. Here, we ...
