Background: Anti-tubulin agents are widely used in the treatment of lymphoma and included important chemotherapy schemes (R-CHOP, ABVD, BEACOP) as well innovative therapeutic approaches utilizing antibody-drug conjugates (ADCs) such brentuximab vedotin polatuzumab vedotin. Recently, we have devoted our efforts to investigation a large family [1,2]oxazole-based derivatives that showed anti-proli...

The gene (GTU1) encoding Tetrahymena thermophila gamma-tubulin was cloned and analyzed. GTU1 is a single-copy, essential gene encoding a conventional gamma-tubulin. HA-tagged GTU1p localizes to four microtubule-organizing centers (MTOCs) in vegetative cells: basal bodies (BBs), macronuclear envelopes, micronuclear envelopes, and contractile vacuole pores. gamma-Tubulin function was studied by p...

More than 20 years ago, biochemical analysis of the eukaryotic cell cytoskeleton revealed the major component proteins. The heterodimeric (α/β) protein tubulin was defined as the building block of microtubules, assembled in a polar manner into specifically arranged protofilaments in the microtubule wall [1]. The next two members of the tubulin protein superfamily were both discovered by genetic...

Although the correlation between beta3-tubulin expression level in tumors has been well correlated with clinical outcome in patients receiving microtubule-targeted agents, the regulation of this protein remains poorly understood. Recently, new insight of regulatory processes was offered with the cloning of the gene promoter. In this study beta3-tubulin gene expression was induced in response to...

gamma-Tubulin exists in fission yeast as the product of an essential gene, encoding a 446 amino acid protein that is 77.3% identical to Aspergillus nidulans gamma-tubulin. The gene disruption caused cell lethality, displaying condensed, undivided chromosomes with aberrant spindle structures. Anti-gamma-tubulin staining showed that gamma-tubulin is located, throughout the wild-type cell cycle, a...

Abstract Background and Purpose: Candida parapsilosis is a common cause of candidemia in children and onco-hematologic patients as well as in patients with septic arthritis, peritonitis, vaginitis, and nail and skin infections. Here, we evaluated intra- and inter-species beta tubulin DNA sequence variation within the C. parapsilosis complex with a view to establishing its utility in the identi...

Strains of Aspergillus containing the benA22 mutation are resistant to benomyl for vegetative growth but do not produce conidia. To test whether conidiation involved an additional benomyl-sensitive tubulin (i.e., was mediated by a tubulin other than the tubulins coded for by the benA locus), a collection of mutants was produced that formed conidia in the presence of benomyl, i.e., were conidiat...

Although seed plants have gamma-tubulin, a ubiquitous component of centrosomes associated with microtubule nucleation in algal and animal cells, they do not have discrete microtubule organizing centers (MTOCs) comparable to animal centrosomes, and the organization of microtubule arrays in plants has remained enigmatic. Spindle development in basal land plants has revealed a surprising variety o...

The a1and a2-tubulin encoding genes were cloned from a goldfish genomic DNA library. a1and a2-tubulin RNA expression was examined in developing and adult retinas. These studies demonstrated increased a1-tubulin RNA in presumptive ganglion cells that grow axons early in retinal development and in adult retinal ganglion cells whose optic axons had been damaged. The a2-tubulin RNA was undetectable...
