How P53 is transported out of the nucleus for degradation during normal cell growth; How kinases that phosphorylate two serine residues at the N-terminal region of P53 are triggered by DNA damage, thereby blocking the exportation of P53; P53 as a target for cancer therapy research.Frankish...
To persist, cells must multiply only in response to specific signals, they must have mechanisms to detect errors in the dupli- cation process, and they must establish a defined sequence for the events of duplication, so that DNA replication, for example, always precedes cell division. In ...
Visible light doesn’t seem to cause muchdirectDNA damage, while UV does. Visible light also doesn’t increase the levels of the inflammatory cytokinesIL-8andTNFαwhile UV does. Blue light doesn’t significantly changethe levelsof p53, the tumour suppressor protein, while UV does. Visible light...
22 the Crossroads 99 Group devised a framework to assess susceptibility testing for breast, ovarian, and colorectal cancer.80 The Crossroads Criteria are based on a simple model of disease progression (see Figure 2), which indicates that screening tests primarily detect genetic susceptibility to ...
Proximity liga- tion assay can theoretically be used to detect interactions on fro- zen and FFPE tissues but this approach needs to be implemented by pathologists in clinical practice. Recent results have extended these observations, showing that different oncogenic forms of...
Clinically, this also makes them harder to detect, as melanocytic antigens are used to detect melanoma metastases in lymph nodes and other organs. We have previously shown that non-canonical Wnt signaling down-regulates MART1 expression [9], and is a key mediator of the switch from a ...

Some aspects of the host response to cytosolic HERV RNA and DNA Full size image A number of cytosolic receptors for DNA such as the DNA-dependent activator of IRFs (DAI) responsible for detecting long dsDNA, the absent in melanoma 2 (AIM2)-like receptors which detect dsDNA and IFN-γ-ind...
Citation47 Interestingly, its mutation decreased tumor growth in vivo and this effect was associated with promoter demethylation and with an enhanced expression of several tumor suppressor genes, including p53. This was explained by the interaction between STAT3 and DNMT1 and the consequent promoter ...
(ii) tRF-3 derived from the 3’ part of mature tRNAs by cleavage at the T loop. The 3’end contains a 3’-CCA terminus. (iii) tRF-1 originated from the 3’trailer from the pre-tRNA. The 3’end has poly-U residues at the end. (iv) i-tRF, which does not belong to tRF-5,...
