PKM2 Interacts With the Cdk1-CyclinB Complex to Facilitate Cell Cycle Progression in Gliomas
PKM2 is a phosphotyrosine-binding glycolytic enzyme upregulated in many cancers, including glioma, and contributes to tumor growth by regulating cell cycle progression. We noted, however, that in multiple glioma cell lines, PKM2 knock-down resulted in an

Nuclear translocation of Cyclin B1 marks the restriction point for terminal cell cycle exit in G2 phase [PDF]
Upon DNA damage, cell cycle progression is temporally blocked to avoid propagation of mutations. While transformed cells largely maintain the competence to recover from a cell cycle arrest, untransformed cells past the G1/S transition lose mitotic ...

Early transformation event from follicular lymphoma: our experience of four cases
Follicular lymphoma (FL) is a mature B-cell lymphoma that can transform into a more aggressive disease such as diffuse large B-cell lymphoma, Burkitt lymphoma, or precursor B-lymphoblastic leukaemia/lymphoma. The process of transformation of FL occurs by

The cyclin-dependent kinase inhibitor KRP2 controls the onset of the endoreduplication cycle during Arabidopsis leaf development through inhibition of mitotic CDKA;1 kinase complexes [PDF]
Exit from the mitotic cell cycle and initiation of cell differentiation frequently coincides with the onset of endoreduplication, a modified cell cycle during which DNA continues to be duplicated in the absence of mitosis. Although the mitotic cell cycle

Cyclin D-Cdk4,6 Drives Cell-Cycle Progression via the Retinoblastoma Protein's C-Terminal Helix. [PDF]
The cyclin-dependent kinases Cdk4 and Cdk6 form complexes with D-type cyclins to drive cell proliferation. A well-known target of cyclin D-Cdk4,6 is the retinoblastoma protein Rb, which inhibits cell-cycle progression until its inactivation by ...

A- and B-type cyclins differentially modulate substrate specificity of cyclin-cdk complexes. [PDF]
Both cyclins A and B associate with and thereby activate cyclin-dependent protein kinases (cdks). We have investigated which component in the cyclin-cdk complex determines its substrate specificity. The A- and B-type cyclin-cdk complexes phosphorylated histone H1 and their cyclin subunits in an indistinguishable manner, irrespective of the catalytic ...

ERRFI1, a neural crest (NC)‐associated gene, was upregulated in melanoma and negatively correlated with the expression of melanocytic differentiation markers and the susceptibility of melanoma cells toward BRAF inhibitors (BRAFi). Knocking down ERRFI1 significantly increased the sensitivity of melanoma cells to BRAFi.

Post-transcriptional regulation of cyclin A and B mRNAs by Bruno 1, Cup, and P-bodies
Summary: Cell cycle progression relies on tightly regulated Cyclin synthesis and degradation, with Cyclins A and B activating CDK1 to drive mitosis. Dysregulation of Cyclin levels is linked to tumorigenesis, underscoring the importance of studying cyclin

Patterns of cyclin A and B1 immunostaining in papillary thyroid carcinoma
[b]Introduction and objectives. [/b]Cyclin A, encoded by CCNA (cyclin A) gene with locus in chromosome 4q27, and cyclin B1, encoded by CCNB1 (cyclin B1) gene with locus in chromosome 5q12, are proteins that play a key role in the passage through the ...
