Cryo-EM structure of the CDK2-cyclin A-CDC25A complex
Nature CommunicationsThe cell division cycle 25 phosphatases CDC25A, B and C regulate cell cycle transitions by dephosphorylating residues in the conserved glycine-rich loop of CDKs to activate their activity.

Aurora B: Hooking up with cyclin-dependent kinases [PDF]
Cell Cycle, 2013 Aurora B (Aurkb) is one of the major protein kinases that ensures the proper execution and fidelity of mitosis.1 A member of the chromosomal passenger complex, Aurkb has been implicated in various mitotic functions, including chromosome-microtubule interactions, sister chromatid cohesion, the spindle-assembly checkpoint and cytokinesis.2 As it is ...

Advanced Science, EarlyView.TUBA1B is consistently upregulated in hepatocellular carcinoma and sustains malignant progression by stabilizing G3BP2. By restraining TRIM25‐associated K48‐linked ubiquitination, TUBA1B preserves the G3BP2–IκBα complex and basal NF‐κB/p65 activity. Concurrent TUBA1B/G3BP2 upregulation identifies an aggressive HCC subgroup with enhanced p65 activation ...

Protein expression patterns of cell cycle regulators in operable breast cancer.
PLoS ONE, 2017 Background-aimTo evaluate the prognostic role of elaborate molecular clusters encompassing cyclin D1, cyclin E1, p21, p27 and p53 in the context of various breast cancer subtypes.MethodsCyclin E1, cyclin D1, p53, p21 and p27 were evaluated with ...

Advanced Science, EarlyView.This study identifies ALYREF as an oncogenic m5C reader in endometrial cancer. ALYREF recognizes NSUN2‐mediated m5C modification on XRCC6 mRNA to enhance transcript stability and increase XRCC6 expression. Elevated XRCC6 activates Wnt/β‐catenin signaling, resulting in accelerated tumor cell proliferation, migration, invasion, and xenograft tumor growth.

The Journal of Cell Biology, 2003 ![Graphic][1] Though normally cytoplasmic (left), cyclin B (red) targeted to the nucleus (right) can start S phase. Hunt/AAASIn mammalian cells the work of the cell cycle is divided between two workhorses: Cdk2/cyclin E for S phase and Cdk1/cyclin B for mitosis. Now, Jonathan Moore,

Is Cyclin D2 a Marker of B-CLL Cell Activation?
Oncology Research Featuring Preclinical and Clinical Cancer Therapeutics, 2009 The most recent studies emphasize a link between B-cell proliferation in vivo and clinical outcome of B-cell chronic lymphocytic leukemia (B-CLL). The expression of cyclin D2 in B-CLL cells isolated from the peripheral blood of 27 untreated patients in relation to the apoptosis ratio both before and 72 h after culture in the absence of growth factors ...

Advanced Science, EarlyView.TGFBI deficiency elevates O‐GlcNAcylation, promoting the transcriptional activation of ADAMTS16 and OGT‐mediated post‐translational modification of ADAMTS16 at Ser1170. This leads to its stabilization and accumulation, driving chondrocyte metabolic disorders and senescent phenotypes, ultimately resulting in fibrocartilage dysfunction and TMJOA ...

Advanced Science, EarlyView.Phase separation of SF3B1 acts as a key regulatory mechanism for dynamic alternative splicing throughout early mouse embryogenesis. Its absence triggers extensive splicing errors, which induce persistent DNA damage, defective cell cycle progression, and failed cell lineage commitment, and ultimately hinder the normal growth and development of ...

Advanced Science, EarlyView.Glucocorticoids (GC) are widely used to reduce inflammation. We show that the glucocorticoid receptor in myeloid cells regulates macrophage cell cycle and genome integrity during muscle regeneration. We demonstrate that dexamethasone administration during the early inflammatory phase delays muscle repair by increasing macrophage proliferation ...
