WebThese opposite roles played by c-Jun are cell type specific and the molecular mechanisms defining these antonymous c-Jun-mediated responses remain incompletely understood. c-Jun activity in transformed cells is regulated by signalling cascades downstream of oncoproteins such as Ras and Raf. Web12 apr. 2024 · The top predicted activated upstream transcription regulator in the BCO tibiae was the myelocytomatosis oncogene (MYC) with a computed activation z-score of 2.121, overlap P -value of 3.09 × 10 –2,...
Web12 apr. 2024 · JMJD5 negatively regulates the expression of TIGAR in a p53-dependent manner. a The protein levels of glucose metabolism genes were measured by western blotting in p53-wt (A549, H1650) and p53-null (H1299, Calu-6) cells after JMJD5 silencing. The mRNA level of glucose metabolism genes was detected by RT-qPCR in A549 (b) … WebBladder cancer (BC) is the 10th most common malignancy worldwide, with an estimated 573,000 new cases and 213,000 deaths in 2024. Available therapeutic approaches are still unable to reduce the incidence of BC metastasis and the high mortality rates of BC patients. Therefore, there is a need to deepen our understanding of the molecular mechanisms …
Web1 jul. 2015 · While the mechanism of activation of p53 in response to DNA damage is well established, the concept that the nucleolus can act as a sensor of cellular stress, and promote the “nucleolar surveillance” or “nucleolar stress pathway” to mediate a p53 response, is relatively new. WebFor this purpose, actinomycin D (ACTD), a known transcription inhibitor of RNA polymerase I which interferes with nucleolar homeostasis by promoting a p53-dependent nucleolar stress response, was used [ 26 ]. Drug cytotoxicity was assessed by measuring the cell viability through MTT assay.
