Identification of the gene encoding cyclin E1 (CCNE1) as a novel IGH translocation partner in t(14;19)(q32;q12) in diffuse large B-cell lymphoma

Haematologica, 2009
In a subset of B-cell malignancies, the genes encoding members of the cyclin D familiy are juxtaposed to immunoglobulin loci through recurrent chromosomal translocations.

Early transformation event from follicular lymphoma: our experience of four cases

Polish Journal of Pathology, 2022
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 microbiome in human skin aging

FEBS Letters, EarlyView.
Age‐related skin changes encompass the well‐known visible phenotypic alterations, together with microbiome dysbiosis and a series of molecular aging hallmarks. These hallmarks characterize not only a fully stablished aged phenotype but also the skin aging process itself.

Both cyclin A delta 60 and B delta 97 are stable and arrest cells in M‐phase, but only cyclin B delta 97 turns on cyclin destruction. [PDF]

The EMBO Journal, 1991
Previous work has established that destruction of cyclin B is necessary for exit from mitosis and entry into the next interphase. Sea urchin cyclin B lacking an N-terminal domain is stable, permanently activates cdc2 kinase, resulting in mitotic arrest, and permanently activates the destruction pathway acting on full length cyclin B.

Ligand‐dependent transcriptional heterogeneity in cell cycle gene expression delays G1/S entry

FEBS Letters, EarlyView.
EGF and HRG induce distinct G1/S progression programs in ErbB2‐amplified BT474 breast cancer cells. Despite activating the potent ErbB2–ErbB3 heterodimer, HRG does not accelerate cell‐cycle entry. Instead, EGF promotes earlier restriction‐point passage via ERK–FOS signaling, whereas HRG activates the AKT–MYC axis, driving transcriptional heterogeneity ...

Post-transcriptional regulation of cyclin A and B mRNAs by Bruno 1, Cup, and P-bodies

iScience
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

Annals of Agricultural and Environmental Medicine, 2015
[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 ...

The ubiquitin system in normal and infected germinal center B cells

FEBS Letters, EarlyView.
The ubiquitin system plays a central role in germinal center (GC) B cells, influencing differentiation to long‐lived memory B cells. Oncogenic gammaherpesviruses gain access to memory B cells by establishing latency in GC B cells. Mapping ubiquitin mechanisms in normal and infected GC B cells will define specific molecular circuits in B cells germane ...

Inhibition of cyclin‐dependent kinases 12/13 using CT7439 as a treatment for colorectal cancer with CDK12 upregulation

Molecular Oncology, EarlyView.
The proposed mechanism of action for the CDK12/13 inhibitor and cyclin K degrader, CT7439. CDK12/13 inhibition interrupts transcription elongation, leading to increased DNA damage that results in cell death. This agent is a potentially novel treatment option for patients with colorectal cancer. Created in BioRender. Cyclin‐dependent kinase (CDK) 12 and

Somatostatin receptor 4 (SSTR4) is a tumor suppressor in cutaneous and head & neck squamous cell carcinomas

Molecular Oncology, EarlyView.
This study identifies somatostatin receptor 4 (Sstr4) as a critical tumor suppressor against skin and head/neck cancers (HNSCC, cSCC, and BCC). The loss of Sstr4 removes a check on cell growth, causing hyperactivation of the MAPK‐ERK signaling pathway (↑).
