This dual mode of action through direct cell infection and extracellular secretion has not been described before and opens up new strategies for eradicating cancer effectively through this kind of combination.
While the activation of myofibroblasts in primary colorectal cancers has been previously described, myofibroblast activation in lymph node metastases has not been described before.
The histological specialization of achieving low skeletal density by extreme resorption of the cortex, described here for the two large-bodied Upper Muschelkalk Nothosaurus species, is unique among secondarily aquatic tetrapods and has not been described before.
Such an activity has not been described before for this actinomycete but is in line with various reports that indicate that actinomycetes have the capacity to degrade to some extent complex molecules, e.g., lignin or lignin-derived compounds (Kirby 2006).
Previous work under native conditions described CrSGD as a more than 1,500 kDa multimerised complex [ 1, 37], although its inclusion in large aggregates has not been described before.
For mouse Nfatc4 we identified two 5′ exons: the previously described 5′ exon, named exon I here, which is homologous to the human exon ID [26], and the 5′-extended exon VI, which has not been described before.
