Gastric Collision Tumors: An Insight into Their Origin and Clinical Significance
(2015)
Collision tumors are rare neoplasms displaying two distinct cell populations developing in juxtaposition to one another without areas of intermingling. They are rare entities with only 63 cases described in English literature. ...
Cancer across the tree of life: cooperation and cheating in multicellularity
(2015-07)
Multicellularity is characterized by cooperation among cells for the development, maintenance and reproduction of the multicellular organism. Cancer can be viewed as cheating within this cooperative multicellular system. ...
A Big Bang model of human colorectal tumor growth.
(NATURE PUBLISHING GROUP, 2015-03-01)
What happens in early, still undetectable human malignancies is unknown because direct observations are impractical. Here we present and validate a 'Big Bang' model, whereby tumors grow predominantly as a single expansion ...
Hippo Stabilises Its Adaptor Salvador by Antagonising the HECT Ubiquitin Ligase Herc4
(2015-06)
Signalling through the Hippo (Hpo) pathway involves a kinase cascade, which leads to the phosphorylation and inactivation of the pro-growth transcriptional co-activator Yorkie (Yki). Despite the identification of a large ...
Ribosome. The complete structure of the 55S mammalian mitochondrial ribosome.
(AMER ASSOC ADVANCEMENT SCIENCE, 2015-04-17)
Mammalian mitochondrial ribosomes (mitoribosomes) synthesize mitochondrially encoded membrane proteins that are critical for mitochondrial function. Here we present the complete atomic structure of the porcine 55S mitoribosome ...
Metabolic plasticity maintains proliferation in pyruvate dehydrogenase deficient cells.
(Springer Science and Business Media LLC, 2015-01-01)
BACKGROUND: Pyruvate dehydrogenase (PDH) occupies a central node of intermediary metabolism, converting pyruvate to acetyl-CoA, thus committing carbon derived from glucose to an aerobic fate rather than an anaerobic one. ...
The hypoxic cancer secretome induces pre-metastatic bone lesions through lysyl oxidase
(NATURE PUBLISHING GROUP, 2015-06-04)
Tumour metastasis is a complex process involving reciprocal interplay between cancer cells and host stroma at both primary and secondary sites, and is strongly influenced by microenvironmental factors such as hypoxia(1). ...
Many private mutations originate from the first few divisions of a human colorectal adenoma.
(WILEY, 2015-11-01)
Intratumoural mutational heterogeneity (ITH) or the presence of different private mutations in different parts of the same tumour is commonly observed in human tumours. The mechanisms generating such ITH are uncertain. ...
Identification of protein complexes that bind to histone H3 combinatorial modifications using super-SILAC and weighted correlation network analysis.
(OXFORD UNIV PRESS, 2015-02-18)
The large number of chemical modifications that are found on the histone proteins of eukaryotic cells form multiple complex combinations, which can act as recognition signals for reader proteins. We have used peptide capture ...
ATM Localization and Heterochromatin Repair Depend on Direct Interaction of the 53BP1-BRCT2 Domain with γH2AX.
(CELL PRESS, 2015-12-15)
53BP1 plays multiple roles in mammalian DNA damage repair, mediating pathway choice and facilitating DNA double-strand break repair in heterochromatin. Although it possesses a C-terminal BRCT2 domain, commonly involved in ...
