Plant genome stability is known to be affected by various abiotic environmental conditions, but little is known about the effect of pathogens. For example, exposure of maize plants to barley stripe mosaic virus seems to activate transposable elements and to cause mutations in the non-infected progeny of infected plants. The induction by barley stripe mosaic(More)
BACKGROUND Host restriction factor APOBEC3G (A3G) blocks human immunodeficiency virus type 1 (HIV-1) replication by G-to-A hypermutation, and by inhibiting DNA synthesis and provirus formation. Previous reports have suggested that A3G is a dimer and its virion incorporation is mediated through interactions with viral or nonviral RNAs and/or HIV-1 Gag. We(More)
Cohesin complex members have recently been identified as putative tumor suppressors in hematologic and epithelial malignancies. The cohesin complex guides chromosome segregation; however, cohesin mutant leukemias do not show genomic instability. We hypothesized that reduced cohesin function alters chromatin structure and disrupts cis-regulatory architecture(More)
Normal hematopoiesis is orchestrated by master regulatory transcription factors that are expressed in specific cell types at discrete differentiation stages (Novershtern et al., 2011; Lara-Astiaso et al., 2014). Tight coordination of these networks maintains the balance between hematopoietic stem/progenitor cell (HSPC) self-renewal and lineage commitment.(More)
The supramolecular compound calix[4]arene C-90 (5,11,17,23-tetra(trifluoro)methyl(phenylsulfonylimino)-methylamino-25,26,27,28-tetrapropoxycalix[4]arene) is shown to efficiently inhibit the ATP hydrolase activity of Ca2+,Mg2+-ATPase in the myometrium cell plasma membrane fraction and also in a preparation of the purified enzyme solubilized from this(More)
Calixarenes are supramolecular compounds interacting with bioactive molecules and ions, causing changes in biochemical and biophysical processes. The aim of this work was to study the effects of calix[4]arenes C-136, C-137, and C-138 at the level of polarization of the rat myometrium mitochondria membrane. The structure of synthesized calix[4]arene(More)
Among different types of calixarenes, the water–soluble ones are of especial interest because of their possible applications in biochemical research. In order to elucidate the nature of aqueous solutions of a cationic amphiphilic calixarene, substituted tetrapropoxy-calix[4]arene bearing hydrophilic choline groups at the upper rim, we studied vis–(More)
