To investigate gene expression in Tribolium castaneum exposed to Beauveria bassiana, reference genes for qPCR were evaluated. Of these, beta-actin, alpha-tubulin, and RPS6 were not stable. The most stable were ribosomal protein genes, RPS3, RPS18, and RPL13a. Syntaxin1, syntaxin6, and E-cadherin may be appropriate for some experimental systems.
This case report describes the fungal dermatitis caused by Neosartorya hiratsukae infection in a household hedgehog confirmed by microscopic examination of conidiophores and DNA analyses including the internal transcribed spacer region, partial beta-tubulin, and the calmodulin gene. It is the first report of a natural N. hiratsukae infection in animals.
There are six members of the tubulin superfamily in eukaryotes. Alpha- and beta-tubulin form a heterodimer that polymerizes to form microtubules, and gamma-tubulin nucleates microtubules as a component of the gamma-tubulin ring complex. Alpha-, beta-, and gamma-tubulin are conserved in all eukaryotes. In contrast, delta- and epsilon-tubulin are conserved in many, but not all, eukaryotes and are...
BACKGROUND Many patients with chronic tendinosis have experienced early pain relief after application of bipolar radiofrequency treatment. It is hypothesized that the mechanism of action may be the acute degeneration and/or ablation of sensory nerve fibers. HYPOTHESIS After ablation or degeneration by bipolar radiofrequency, nerve fibers will have the ability to regenerate with time. STUDY ...
Tubulin isotype distribution may play a role in the development of anti-cancer anti-tubulin drug resistance as well as in drug efficacy and specificity. Stepwise selection was used to establish non-small cell lung carcinoma (NSCLC) H460 cells resistant to combretastatin A-4 (CA4), paclitaxel or vinblastine. The results demonstrated that the rate of CA4 drug resistance development was slower tha...
Cyclostreptin (1), a natural product from Streptomyces sp. 9885, irreversibly stabilizes cellular microtubules, causes cell cycle arrest, evades drug resistance mediated by P-glycoprotein in a tumor cell line and potently inhibits paclitaxel binding to microtubules, yet it only weakly induces tubulin assembly. In trying to understand this paradox, we observed irreversible binding of synthetic c...
Wild-type Saccharomyces cerevisiae tubulin does not bind the anti-mitotic microtubule stabilizing agent paclitaxel. Previously, we introduced mutations into the S. cerevisiae gene for beta-tubulin that imparted paclitaxel binding to the protein, but the mutant strain was not sensitive to paclitaxel and other microtubule-stabilizing agents, due to the multiple ABC transporters in the membranes o...
gamma-Tubulin is a conserved essential protein required for assembly and function of the mitotic spindle in humans and yeast. For example, human gamma-tubulin can replace the gamma-tubulin gene in Schizosaccharomyces pombe. To understand the structural/functional domains of gamma-tubulin, we performed a systematic alanine-scanning mutagenesis of human gamma-tubulin (TUBG1) and studied phenotype...
Circumscribing major eukaryote groups and resolving higher order relationships between them are among the most challenging tasks facing molecular evolutionists. Recently, evidence suggesting a new supergroup (the Excavata) comprising a wide array of flagellates has been collected. This group consists of diplomonads, retortamonads, Carpediemonas, heteroloboseans, Trimastix, jakobids, and Malawim...
Class III beta-tubulin isotype (betaIII-tubulin) is widely regarded as a neuronal marker in developmental neurobiology and stem cell research. To test the specificity of this marker protein, we determined its expression and distribution in primary cultures of glial fibrillary acidic protein (GFAP)-expressing astrocytes isolated from the cerebral hemispheres of 2 human fetuses at 18 to 20 weeks ...
