Cytokinesis multinucleated

WebMultinucleated cells could be also induced by 12-O-tetradecanoylphorbol 13-acetate (TPA) in 5F9A cells. This effect was mediated by protein kinase C. Possible mechanisms of multinucleation by TPA were hypothesized to be either karyokinesis without cytokinesis or … WebTo better understand the mechanisms underlying cytokinesis B and C, we introduced mutations into mhcA- cells and isolated clones that consistently gave rise to large, multinucleated cells. One such clone was found to have a disrupted talA gene, which codes for one of two Dictyostelium homologues of talin.

WebJun 18, 2024 · In our study, menin depletion led to defects in spindle assembly and chromosome congression during early mitosis, lagging chromosomes during anaphase, defective cytokinesis, multinucleated interphase cells, and cell death. In addition, pharmacological inhibition of the menin-MLL1 interaction also led to similar cell division … Multinucleate cells (also known as multinucleated or polynuclear cells) are eukaryotic cells that have more than one nucleus per cell, i.e., multiple nuclei share one common cytoplasm. Mitosis in multinucleate cells can occur either in a coordinated, synchronous manner where all nuclei divide simultaneously or asynchronously where individual nuclei divide independently in time and space. Certain organisms may have a multinuclear stage of their life cycle. For example, slime molds h…

WebMar 1, 2024 · This leads to conditions such as aneuploidy, where a cell has several extra or missing chromosomes; polyploidy, where cytokinesis does not occur and a cell has more than a diploid set of chromosomes; or multinucleated cells, where more than one nucleus is present in a cell. These can lead to genetic disordersor even cancers. WebMar 31, 2009 · Background: Multinucleated cells are frequently seen in association with a malignant neoplasm. Some of these multinucleated cells are considered to be neoplastic. The mechanism of neoplastic multinucleation remains unknown, but is considered to be induced by either cell-cell fusion or acytokinetic cell division.
