متن کاملTraces of Greek Mythology in Samuel Beckett’s Waiting for Godot
This study addresses Samuel Beckett’s most celebrated play, Waiting for Godot, in an effort to analyze its characters from a novel perspective. Since Greek mythology has been undisputedly influential on Western culture and literature, the researcher attempts to investigate a connection between Greek mythology and the play. This study aims to reveal that even after more than fifty seven years of...
متن کاملEndocytic and NBT-reduction activities and TNF expression by macrophages and monocytes of the armadillo (Dasypus novemcinctus)
The armadillo could be considered as an experimental model for leprosy studies. Mycobacterium leprae main host cells are macrophages and Schwann cells. However, endocytosis and germicidal activities of armadillo macrophages and monocytes have not yet been evaluated. The aim of this research was to evaluate endocytosis and NBT-reduction activities of monocyte-derived macrophages (MDM) and monocy...
متن کاملMetabolic flux-driven sialylation alters internalization, recycling, and drug sensitivity of the epidermal growth factor receptor (EGFR) in SW1990 pancreatic cancer cells
In prior work we reported that advanced stage, drug-resistant pancreatic cancer cells (the SW1990 line) can be sensitized to the EGFR-targeting tyrosine kinase inhibitors (TKIs) erlotinib and gefitinib by treatment with 1,3,4-O-Bu3ManNAc (Bioorg. Med. Chem. Lett. (2015) 25(6):1223-7). Here we provide mechanistic insights into how this compound inhibits EGFR activity and provides synergy with TK...
متن کاملIndependent Neuronal Origin of Seizures and Behavioral Comorbidities in an Animal Model of a Severe Childhood Genetic Epileptic Encephalopathy
The childhood epileptic encephalopathies (EE's) are seizure disorders that broadly impact development including cognitive, sensory and motor progress with severe consequences and comorbidities. Recently, mutations in DNM1 (dynamin 1) have been implicated in two EE syndromes, Lennox-Gastaut Syndrome and Infantile Spasms. Dnm1 encodes dynamin 1, a large multimeric GTPase necessary for activity-de...
