  2021-03-12

  

  In addition to EGFR, other receptor tyrosine kinases (RTKs) also play roles in the tumor progression under hypoxia, especially hepatocyte growth factor receptor (cMet) (Le et al., 2012). Our data suggested that unlike EGFR, hypoxia had no apparent effect on cMet Eptifibatide (data not shown), sugge

  Discussion The regulation of intracellular cholesterol levels is a biological process of vital importance for cellular function and integrity, and involves robust transcriptional and post-transcriptional mechanisms that are sensitive to metabolic feedback control. Amongst post-transcriptional mec

  Another example of negative regulation is the inhibition of the yeast endosome-associated DUB Doa4 by Rfu1 (free ubiquitin chains 1). In a yeast genetics screen, deletion of Rfu1 was serendipitously found to alter global ubiquitin levels [69]. DUBs can regulate these levels by liberating conjugated

  2021-03-12

  

  DNA methylation is associated with transcriptional silencing of tumor suppressors or other genes important for normal cellular function and plays an important role in the development of cancer and other diseases (such as breast and colorectal cancers) [19]. DNA methyltransferases (MTases) are a fami

  Fragment-based drug discovery (FBDD) is a powerful method to discover drug leads and has been widely adopted in both academia and industry. FBDD can be used to explore chemical BGP-15 space with libraries which are smaller in size, producing drug leads with high ligand-binding efficiency. It also

  The Δ32 mutation in Caucasian people of European heritage is quite common but extremely rare in Asian and African countries (Huang et al., 1996). We recently reported the presence of this mutation from India (Husain et al., 1998a) and established the complete inheritance pattern (Husain et al., 1998

  2021-03-11

  

  In addition to its HEAT repeats, CRM1 also possesses a C-terminal extension (C-extension, residues 1032–1071), composed of a helix (C-helix) followed by a short stretch of residues (C-tail). In the absence of Ran, the C-extension adopts a conspicuous conformation that bridges across the ring-shaped

  Results Discussion Adaptive drug resistance is a major challenge to the clinical success of cancer therapies. Incomplete inhibition of oncogenic signaling allows survival of “drug-tolerant” tumor cells, which persist in that state for variable periods before acquiring additional genetic mutati

  The question remains, however as to the downstream signaling by Epacs that contributes to persistent sensitization of sensory neurons. Activation of the Ras family of GTPases by Epac1 (RapGEF3) or Epac2 (RapGEF4) (Bos, 2003, de Rooij et al., 1998) is linked to a number of downstream signaling effect

  The development of novel approaches to study GPCR-mediated transactivation in live Isochlorogenic acid C is important, and this study describes a unique BRET-based quantification of Grb2 recruitment to the EGFR as a direct readout of GPCR-mediated transactivation. We have previously used the recruit

  Downregulation of tumor suppressors is a major factor that leads to tumorigenesis. Phosphatase and tensin homolog deleted on chromosome 10 (PTEN), a common tumor suppressor, the TCS JNK 5a of which is often downregulated or even absent in the majority of human cancers, functions as a phosphatase to
