Bub1 kinase in the regulation of mitosis
Accurate chromosome segregation is required for cell survival and organismal development. During mitosis, the spindle assembly checkpoint acts as a safeguard to maintain the high fidelity of mitotic chromosome segregation by monitoring the attachment of ...

Molecular and cellular paradigms of multidrug resistance in cancer
Abstract Background The acquisition of resistance to chemotherapy is a major hurdle in the successful application of cancer therapy. Several anticancer approaches, including chemotherapies, radiotherapy, surgery and targeted therapies are being employed for the treatment of cancer.

Alcohol extracts of Chinese bayberry branch induce S‐phase arrest and apoptosis in HepG2 cells
The alcohol extracts of Chinese bayberry Myrica rubra branches (MRBE) effectively inhibited the proliferation of HepG2 cells by inducing cell cycle arrest in S phase and promoting apoptosis, with this arrest potentially mediated by the activation of p21–Cyclin–CDK (cyclin‐dependent kinase) complex signaling pathways.

Kinase Signaling in the Spindle Checkpoint [PDF]
The spindle checkpoint is a cell cycle surveillance system that ensures the fidelity of chromosome segregation. In mitosis, it elicits the "wait anaphase" signal to inhibit the anaphase-promoting complex or cyclosome until all chromosomes achieve bipolar microtubule attachment and align at the metaphase plate. Because a single kinetochore unattached to

Abstract Chromosomal instability is a common feature in malignant tumors. Previous studies have indicated that inactivation of the classical tumor suppressor genes RB1, CDKN2A, and TP53 may contribute to chromosomal aberrations in cancer by disrupting different aspects of the cell cycle and DNA damage checkpoint machinery.

During mitosis, correct bipolar chromosome attachment to the mitotic spindle is an essential prerequisite for the equal segregation of chromosomes. The spindle assembly checkpoint can prevent chromosome segregation as long as not all chromosome pairs ...

Toward a systems-level view of mitotic checkpoints [PDF]
Reproduction and natural selection are the key elements of life. In order to reproduce, the genetic material must be doubled, separated and placed into two new daughter cells, each containing a complete set of chromosomes and organelles. In mitosis, transition from one process to the next is guided by intricate surveillance mechanisms, known as the ...

Modeling Dual Pathways for the Metazoan Spindle Assembly Checkpoint [PDF]
Using computational modelling, we investigate mechanisms of signal transduction focusing on the spindle assembly checkpoint where a single unattached kinetochore is able to signal to prevent cell cycle progression. This inhibitory signal switches off rapidly once spindle microtubules have attached to all kinetochores.

Chromosome cohesion and the spindle checkpoint [PDF]
Accurate chromosome segregation constitutes the basis of inheritance. Mistakes in chromosome segregation during mitosis lead to aneuploidy, a common feature of tumors. The accuracy of chromosome segregation is governed by a complex network of processes which ensure that each daughter cell receives the correct number of chromosomes.
