In the 1970s, Paul Nurse and Leland Hartwell pioneered the search for mutations that affected the cell cycle in both of these yeastspecies. They identified mutants by their arrest at distinct stages of the cell cycle, and dubbed these cell-division-cycle (cdc) mutants, or depending on their ...
Again, this structural heterogeneity is determined by specific features of the amino acid sequences of IDPs/IDRs. In fact, in comparison with ordered proteins and domains, most IDPs/IDRs are systematically depleted in order-promoting residues (Cys, Trp, Tyr, Phe, Ile, Leu, Val, and Asn), ...
In the late stages of cancer, cells break through normal tissue boundaries and metastasize (spread) to new sites in the body. How Do Cancer Cells Differ from Normal Cells? In normal cells, hundreds of genes intricately control the process of cell division. Normal growth requires a balance ...

We microsurgically introduced ESCs into 8-cell embryos and examined how their presence affects the proportion of differentiative divisions of the blastomeres at the 8-, 16-, and 32-cell stages and, in consequence, the number of embryo-derived cells in the ICM of the blastocysts. We show ...
model group were in different developmental stages, and almost all GC cells in the aging model group were in the period of regeneration but nondivision, proliferation, and apoptosis, while almost all GC cells in the HA-MSC-treated group were in the state of division and differentiation (Fig....
division cycle clearly show no sign of DNA inside their buds (see Fig.2Aand2B). Presence of DNA was observed to occur in both mother and bud cells only at later budding stages (Fig.2Cand onwards). Since this was not a time-lapse result, we could not interpret how long after the ...
Injury to contractile organs such as the heart, vasculature, urinary bladder and gut can stimulate a pathological response that results in loss of normal contractility. PDGF and TGFβ are among the most well studied initiators of the injury response and have been shown to induce aberrant contracti...
a fusion protein of the N-terminal portion of cyclin B1 and eGFP that behaves like full-length cyclin B1 in terms of expression during the cell cycle, i.e. it is degraded in G0/G1 phases so that cells are GFP negative (GFP-), and it is stable in S/G2/M stages rendering cells ...
