Molecular Oncology, EarlyView.Loss of primary cilia in endothelial cells promotes EndMT and vascular abnormalities in the ovarian tumor microenvironment through EphA2 activation. Using human samples, in vitro models, and endothelial‐specific Kif3a‐knockout mice, we show that primary cilia loss drives the acquisition of cancer‐associated fibroblast‐like phenotypes, thereby ...

Molecular Oncology, EarlyView.Comprehensive cancer centre (CCCs) and CCCs of Excellence (CCCoE) integration in healthcare. Through outreach to surrounding community hospitals, CCCs enable wider access to top‐clinical cancer treatments and care, thereby facilitating the swift enrolment of patients into data‐rich clinical trials (PI‐initiated trials testing new concepts, drug ...

Genomics‐led approach to drug testing in models of undifferentiated pleomorphic sarcoma
Molecular Oncology, EarlyView.GA text Genomic data from undifferentiated pleomorphic sarcoma patients and preclinical models were used to inform a targeted drug screen. Selected compounds were tested in 2D and 3D cultures of UPS cell lines. A combination of trametinib and infigratinib was synergistic in the majority of UPS cell lines tested, which was further confirmed in an ex ...

Molecular Oncology, EarlyView.This study identifies nuclear YB‐1 S102 phosphorylation as a marker associated with KRAS and FBXW7 mutations in colorectal cancer. Mutated KRAS correlates specifically with nuclear, not cytoplasmic, S102 YB‐1. These findings provide the first ex vivo evidence of this link in CRC and suggest future studies should assess the prognostic and therapeutic ...

Macromolecules and the Origin of Life [PDF]
Origins of Life, 1974 From our knowledge of present day organisms, it is hard to imagine a living assembly, even at its most primitive stage, without macromolecules. In order to look for the macromolecules which possibly participated in the assembly of the primitive organisms, the reaction and formation of polymers in HCN under irradiation of ultraviolet ray of 184.9 nm ...

Angewandte Chemie International Edition in English, 1973
AbstractThe theory of the evolution of the species, which is today widely accepted, requires a starting point. It is postulated that the biological starting point could have emerged only if chemical evolution had preceded it. Experiments are described which show the formation of organic substances from inorganic gases under conditions which prevailed ...

Origins of Life and Evolution of Biospheres, 2005
Sea ice occurs abundantly at the polar caps of the Earth and, probably, of many other planets. Its static and dynamic properties that may be important for prebiotic and early biotic reactions are described. It concentrates substrates and has many features that are important for catalytical actions. We propose that it provided optimal conditions for the

, 2014 Biological evolution begins with the origin of life, but the subject is the perhaps the most interdisciplinary of any in science. Understanding how life began on Earth requires knowledge of the astronomical, geological, and atmospheric settings. However, those settings are in turn dependent on knowing the time period when life arose, which comes from ...

Hypercycles and the origin of life
Nature, 1979Perhaps the most difficult step to explain in the origin of life is that from the replication of molecules (RNA for example) in the absence of specific proteins, to the appearance of polymerases and other proteins involved in the replication of RNA and themselves coded for by that RNA.

Random chemical reactions in the Earth's primitive hydrosphere could have generated no more than 200 bits of information, whereas the first Darwinian organism must have encoded about a million bits, and therefore could not have arisen by chance. This information gap is bridged by separating reproduction from organism, and postulating a reproductive ...
