  MTT results show that, both pancreatic cell lines were quite sensitive to camptothecin (CPT), a well known topoisomerase I poison. Interestingly, CPT does not show any selectivity over cancer cell lines probably due to the duplication times for cancerous (MIA PaCa-2) and immortalized healthy (HPDEC)

  2021-04-12

  

  Dopamine activity in the PFC and striatum may be antagonistic, meaning that lower levels of dopamine in the striatum tend to correspond to higher levels of dopamine in the PFC and vice versa (Cools and D'Esposito, 2011; Tunbridge et al., 2006). Human PET studies have reported that dopaminergic PFC f

  Introduction Human cytomegalovirus (CMV) is a herpesvirus which has a ubiquitous and worldwide distribution, and is the most frequent cause of congenital infection (Kenneson and Cannon, 2007). The prevalence is around 0.5–1% of all live births and is the leading cause of sensorineural hearing loss

  Conventional assays rely on a comparable transformation of the target analytes and the structurally similar (but not identical) proxy substrates and are commonly used to measure individual enzyme activities in (pre-treated) intact sludge flocs (Burgess and Pletschke, 2008a, Gessesse et al., 2003, Yu

  Results and discussion The effects of hypoxia, a combination of shear stress and hyperoxia, and a combination of shear stress and hypoxia in BAECs were assessed at 0, 15, 30, 60, 120, and 180 min. Changes in phosphorylation levels of eNOS at Ser635 were investigated using immunoblotting, and repr

  This investigation establishes that there is a genetic difference in the enolase loci that correlates with both vegetative growth and virulence phenotypes. DNA sequence analysis of enolase loci from seven P. larvae strains reveals a single SNP that alters the protein sequence at position 331 (Table

  Introduction Our understanding of how ligands interact with G protein coupled receptors is evolving, particularly the recognition that some have the ability to preferentially activate a subset of intracellular signalling cascades – so called pathway biased ligands [1]. Additionally, it is now acc

  Materials and methods Results Assay of botulinum toxin activity is critical for the risk-assessment, diagnosis, and treatment of botulism cases. The frequently encountered active forms of the toxin are; L chain (inside intoxicated neuronal cells), BoNT (in the blood stream of a botulism patient,

  Collectively, the results presented here provide new insights into ligand binding, clustering, spatial distribution, and phosphorylation of DDR1b and DDR2 in response to soluble collagen I. As depicted in the cartoon of Scheme 1, we postulate a model in which the spatial distribution and assembly of

  In this study we generated mice in which the native Bcl6 locus was engineered to produce a form of Bcl6 containing a mutant RD2 domain that disrupts its repressor function. We found that RD2 domain is essential for pre-GC B cell differentiation and clustering into nascent GC within follicles, in par

  In Arabidopsis the quartet1 (qrt1) mutant enables the same type of analysis of gametophytes (pollen) in sets of four (tetrads) derived from individual meioses 61., 62.. Pollen tetrads from one accession (Columbia-0) are used to pollinate a second polymorphic accessions (Landsberg erecta) resulting i

  Introduction Coping with DNA damage is possible thanks to surveillance mechanisms (checkpoints), that detect the problem and promote its solution [1], [2], and to repair and tolerance pathways that remove the lesions or reduce the damage consequences [3], [4]. Failures in these processes have a h

  DGKs bind and regulate other signalling proteins Based on the evidence noted above, DGKs achieve specificity of function through a combination of post-translational modifications, the availability of cofactors, and through the availability and access to substrate DAG. DGKs appear to achieve an ad

  Keratin 8 (K8) has been identified as the first intermediate filament expressed during development in amphibians and mammals. In zebrafish, a type II cytokeratin 8 (zf-K8) cDNA has been cloned. zf-K8 gene was maternally inherited and expressed in all surface cells throughout the embryonic stages old
