A novel chloride channel localizes to Caenorhabditis elegans spermatids and chloride channel blockers induce spermatid differentiation.
Caenorhabditis elegans spermatogenesis is especially suited for studies of nonrandom cytoplasmic segregation during cellular differentiation. Spermatocytes separate from an anuclear cytoplasmic core and undergo two sequential divisions. During the second division, intracellular organelles segregate specifically to spermatids as they bud from an anuclear residual body. We have applied patch-clam...
متن کاملacr-23 Encodes a Monepantel-Sensitive Channel in Caenorhabditis elegans
Monepantel is a member of the recently identified class of anthelmintics known as the amino-acetonitrile derivatives (AADs). Monepantel controls all major gastro-intestinal nematodes in sheep including those that are resistant to the classical anthelmintics. Previous studies have shown that the Caenorhabditis elegans acr-23 and the Haemonchus contortus Hco-mptl-1 genes may be prominent targets ...
متن کاملpassivity in waiting for godot and endgame: a psychoanalytic reading
this study intends to investigate samuel beckett’s waiting for godot and endgame under the lacanian psychoanalysis. it begins by explaining the most important concepts of lacanian psychoanalysis. the beckettian characters are studied regarding their state of unconscious, and not the state of consciousness as is common in most beckett studies. according to lacan, language plays the sole role in ...
A Tyramine-Gated Chloride Channel Coordinates Distinct Motor Programs of a Caenorhabditis elegans Escape Response
A key feature of escape responses is the fast translation of sensory information into a coordinated motor output. In C. elegans, anterior touch initiates a backward escape response in which lateral head movements are suppressed. Here, we show that tyramine inhibits head movements and forward locomotion through the activation of a tyramine-gated chloride channel, LGC-55. lgc-55 mutant animals ha...
متن کاملInto ion channel and transporter function. Caenorhabditis elegans ClC-type chloride channels: novel variants and functional expression.
Six ClC-type chloride channel genes have been identified in Caenorhabditis elegans, termed clh-1 through clh-6. cDNA sequences from these genes suggest that clh-2, clh-3, and clh-4 may code for multiple channel variants, bringing the total to at least nine channel types in this nematode. Promoter-driven green fluorescent protein (GFP) expression in transgenic animals indicates that the protein ...
