Using inducible degradation to characterise the roles of TRIP13 and CEP57 in mitosis
(Institute of Cancer Research (University Of London), 2021-05-31)
DNA and centrosomes are both semi-conservatively replicated once per cell cycle and it is essential that the DNA and centrosomes are divided equally between daughter cells in mitosis. When this fails, it can lead to ...
Autoinhibition Mechanism of the Ubiquitin-Conjugating Enzyme UBE2S by Autoubiquitination.
(CELL PRESS, 2019-08-06)
Ubiquitin-conjugating enzymes (E2s) govern key aspects of ubiquitin signaling. Emerging evidence suggests that the activities of E2s are modulated by posttranslational modifications; the structural underpinnings, however, ...
A high-content RNAi screen reveals multiple roles for long noncoding RNAs in cell division.
(NATURE PUBLISHING GROUP, 2020-04-15)
Genome stability relies on proper coordination of mitosis and cytokinesis, where dynamic microtubules capture and faithfully segregate chromosomes into daughter cells. With a high-content RNAi imaging screen targeting more ...
PLK1 Activation in Late G2 Sets Up Commitment to Mitosis.
(CELL PRESS, 2017-06-06)
Commitment to mitosis must be tightly coordinated with DNA replication to preserve genome integrity. While we have previously established that the timely activation of CyclinB1-Cdk1 in late G2 triggers mitotic entry, the ...
The midbody interactome reveals unexpected roles for PP1 phosphatases in cytokinesis.
(NATURE PUBLISHING GROUP, 2019-10-04)
The midbody is an organelle assembled at the intercellular bridge between the two daughter cells at the end of mitosis. It controls the final separation of the daughter cells and has been involved in cell fate, polarity, ...
CHK1 Inhibition Radiosensitizes Head and Neck Cancers to Paclitaxel-Based Chemoradiotherapy.
(AMER ASSOC CANCER RESEARCH, 2016-09-01)
Head and neck squamous cell carcinoma (HNSCC) is a leading cause of cancer-related deaths, with increasingly more cases arising due to high-risk human papillomavirus (HPV) infection. Cisplatin-based chemoradiotherapy is a ...
Cyclin B1 is essential for mitosis in mouse embryos, and its nuclear export sets the time for mitosis.
(ROCKEFELLER UNIV PRESS, 2018-01-02)
There is remarkable redundancy between the Cyclin-Cdk complexes that comprise the cell cycle machinery. None of the mammalian A-, D-, or E-type cyclins are required in development until implantation, and only Cdk1 is ...
Single-Cell Dynamics Determines Response to CDK4/6 Inhibition in Triple-Negative Breast Cancer.
(AMER ASSOC CANCER RESEARCH, 2017-09-15)
Purpose: Triple-negative breast cancer (TNBC) is a heterogeneous subgroup of breast cancer that is associated with a poor prognosis. We evaluated the activity of CDK4/6 inhibitors across the TNBC subtypes and investigated ...
TOPBP1 recruits TOP2A to ultra-fine anaphase bridges to aid in their resolution.
(NATURE PUBLISHING GROUP, 2015-03-12)
During mitosis, sister chromatids must be faithfully segregated to ensure that daughter cells receive one copy of each chromosome. However, following replication they often remain entangled. Topoisomerase IIα (TOP2A) has ...
