UBE3A/E6-AP regulates cell proliferation by promoting proteasomal degradation of p27
The UBE3A/E6-AP is known to function both as an E3 ubiquitin ligase of the ubiquitin proteasome system and as a transcriptional coactivator. E6-AP shows brain-specific imprinting and loss of function of maternally inherited E6-AP causes Angelman syndrome.

MAST1 modulates neuronal differentiation and cell cycle exit via P27 in neuroblastoma cells
Although 19p13.13 microdeletion syndrome has been consistently associated with intellectual disability, overgrowth, and macrocephaly, the underlying mechanisms remain unclear.

Thyroid status modulates T lymphoma growth via cell cycle regulatory proteins and angiogenesis [PDF]
We have shown in vitro that thyroid hormones (THs) regulate the balance between proliferation and apoptosis of T lymphoma cells. The effects of THs on tumor development have been studied, but the results are still controversial.

Accumulation of the cyclin-dependent kinase inhibitor p27/Kip1 and the timing of oligodendrocyte differentiation [PDF]
Many types of vertebrate precursor cells divide a limited number of times before they stop and terminally differentiate. In no case is it known what causes them to stop dividing. We have been studying this problem in the proliferating precursor cells that give rise to postmitotic oligodendrocytes, the cells that make myelin in the central nervous ...

Cell Cycle Control by Xenopus p28^(Kix1) a Developmentally Regulated Inhibitor of Cyclin-dependent Kinases [PDF]
We have isolated Xenopus p28^(Kix1), a member of the p21^(CIP1)/p27^(KIP1)/p57^(KIP2) family of cyclin-dependent kinase (Cdk) inhibitors. Members of this family negatively regulate cell cycle progression in mammalian cells by inhibiting the activities of

Cip/Kip cyclin-dependent protein kinase inhibitors and the road to polyploidy [PDF]
Cyclin-dependent kinases (CDKs) play a central role in the orderly transition from one phase of the eukaryotic mitotic cell division cycle to the next.

Dormant cancer cells can hide in distant organs for years, evading treatment and the immune system. This review highlights how signals from the surrounding tissue and immune environment keep these cells inactive or trigger their reawakening. Understanding these mechanisms may help develop therapies to eliminate or control dormant cells and prevent ...

High p27 protein levels in chronic lymphocytic leukemia are associated to low Myc and Skp2 expression, confer resistance to apoptosis and antagonize Myc effects on cell cycle [PDF]
This is an open-access article distributed under the terms of the Creative Commons Attribution License.-- et al.Myc (c-Myc) counteracts p27 effects, and low p27 usually correlates with high Myc expression in human cancer.

A regulatory axis involving APE1, AUF1, and miR‐221 is proposed. Pri‐miR‐221 is processed by DROSHA and DICER to generate mature miR‐221, which targets p27Kip1 mRNA. APE1 and AUF1 compete for pre‐miR‐221 binding. Reduced APE1/AUF1 levels impair miR‐221 biogenesis, decrease p27Kip1 mRNA degradation, and promote cell cycle progression, chemoresistance ...
