Tubulin isotypes are known to regulate the stability and dynamics of microtubules, and are also involved in the development of resistance against microtubule-targeted cancer drugs. Indanocine, a potent microtubule depolymerizing agent, is highly active against multidrug-resistant (MDR) cancer cells without affecting normal cells. It is known to disrupt microtubule dynamics in cells and induce a...

Displaying a strong antiproliferative activity on a wide variety of cancer cells, EAPB0203 and EAPB0503 belong to the imidazo[1,2-a]quinoxalines family of imiquimod structural analogues. EAPB0503 has been shown to inhibit tubulin polymerization. The aim of the present study is to characterize the interaction of EAPB0203 and EAPB0503 with tubulin. We combine experimental approaches at the cellul...

Species in the genus Gliocephalotrichum (= Leuconectria) (Hypocreales, Nectriaceae) are soilborne fungi, associated with post-harvest fruit spoilage of several important tropical fruit crops. Contemporary taxonomic studies of these fungi have relied on morphology and DNA sequence comparisons of the internal transcribed spacer region of the nuclear rDNA (ITS) and the β-tubulin gene regions. Empl...

Mesenchymal stem cells (MSCs) have the ability to differentiate into neuronal like cells under appropriate culture condition. In this study, we investigated whether MSCs derived from human peripheral blood (PB-MSCs) can differentiate into neuronal like cells by synergic effect of the growth factors EGF, bFGF and Noggin. For this purpose, the expression of five neuronal markers (Nestin, β III tu...

Melanopus is a morphological group of Polyporus which contains species with a black cuticle on the stipe. In this article, taxonomic and phylogenetic studies on Melanopus group were carried out on the basis of morphological characters and phylogenetic evidence of DNA sequences of multiple loci including the internal transcribed spacer (ITS) regions, the large subunit nuclear ribosomal RNA gene ...

Axotomized central neurons of most invertebrate species demonstrate a strong regenerative capacity, and as such may provide valuable molecular insights and new tools to promote axonal regeneration in injured mammalian neurons. In this study, we identified a novel molluscan protein, caltubin, ubiquitously expressed in central neurons of Lymnaea stagnalis and locally synthesized in regenerating n...

Tumor resistance to antitubulin drugs resulting from P-glycoprotein (Pgp) drug-efflux activity, increased expression of the βIII tubulin isotype, and alterations in the drug-binding sites are major obstacles in cancer therapy. Consequently, novel antitubulin drugs that overcome these challenges are of substantial interest. Here, we study a novel chemotype named furan metotica that localizes to ...
