  In studies directed toward the development of sequence-specific major-groove binding small ethionamide [11], we desired a non-intercalating molecular scaffold that could direct attached moieties into the major groove. As an initial step toward this goal, we wished to study the DNA binding mode and

  Introduction A variety of means, including UV irradiation, dNTP depletion, and oncogene activation at precancerous lesions, induce replication stress, which causes replication errors if left undealt with (Hills and Diffley, 2014, Zeman and Cimprich, 2014). Eukaryotic cells have developed the DNA

  2021-04-01

  

  For a physiologically relevant interaction, ligand and receptor have to be expressed in the same place. Collagen II is found primarily in cartilage. DDR2 is expressed in proliferating chondrocytes in vivo, and its staining pattern in tibial growth plates is similar to that of collagen II. In additio

  2021-04-01

  

  Collagen compaction and alignment are generated by cell-mediated contractile forces (Stopak and Harris, 1982). The transmission of actomyosin forces to collagen has been mainly attributed to integrins and the activation of the Rho-ROCK pathway (Clark et al., 2007, Kural and Billiar, 2013, Provenzano

  The collagen field undoubtedly regains attractiveness with the emergence of new concepts (cell niche, regulation of growth factor bioavailability, mechanotransduction, cell microenvironment sensing) and new tools to investigate their in vivo functions (atomic force microscopy (AFM), second harmonic

  All of these experiments in GM matter injury models have identified an array of signaling mechanisms that are potentially important. First, Kim et al. proposed that CK2 acts as a negative modulator of NADPH oxidase [55]. Then Blanquet et al. [50] found that increased CK2 correlated with inhibition o

  Acknowledgments Introduction Cell cycle arrest or delay may occur at 3 major checkpoints, i.e. G1/S, intra-S and G2/M. p53 has a central role in controlling the G1/S checkpoint, and its loss or deactivation, occurring in the majority of cancers, forces cancer cells to rely on the S and G2/M ch

  Currently, phosphodiesterase type 5 (PDE-5) inhibitors are used widely as the first- line oral treatment for erectile dysfunction of varying causes. Radical prostatectomy for the treatment of prostate cancer is frequently associated with erectile dysfunction, and this type of erectile dysfunction is

  Assessing DUB activity The Ub field has benefited greatly from the past efforts of biochemists and chemical biologists who have reconstituted Ub signals in vitro and generated tools for capturing or measuring DUB activities, many of which can be readily produced or are commercially available (Ekk

  Material and methods Results Discussion Ligase IV is essential for the final ligation of DSBs through the NHEJ pathway. Its co-factor, XRCC4, has been shown to be important for increasing its activity and stability. Interaction between these two factors have been mapped to the linker region

  2021-03-30

  

  The most significant source of DAG originates from the PLC family of enzymes, which produces DAG in an agonist-regulated reaction. PLCs constitute a wide family of enzymes acting on both phosphatidilinositols (PI) and phosphatidilcoline (PC) (Li et al., 2010) in the plasma membrane and other intrace

  Extracellular uridine can be transported across the cell membrane to enter the nucleotide salvage pathway. A colon cancer cell line supplemented with uridine was capable of growing normally in the presence of 1 μM brequinar (Peters et al., 1992). The supplemented uridine may be transported into the

  To be a qualified non-specific CYP inhibitor used as an in vitro or in vivo screening tool to distinguish CYP involvement in the overall metabolism, a complete inhibition of the entire metabolism catalyzed by CYPs in a simple experiment is desired. Based on our results, 100 μM atipamezole can comple
