FLT3 and FLT3-ITD phosphorylate and inactivate the cyclin-dependent kinase inhibitor p27Kip1 in acute myeloid leukemia

open access: yesHaematologica, 2017
P27Kip1 (p27) can prevent cell proliferation by inactivating cyclin-dependent kinases. This function is impaired upon phosphorylation of p27 at tyrosine residue 88. We observed that FLT3 and FLT3-ITD can directly bind and selectively phosphorylate p27 on

Expression of cyclin-dependent kinase inhibitor p27kip1in malignant lymphomas [PDF]

open access: yesJournal of Korean Medical Science, 2000
p27kip1 is a cyclin-dependent kinase inhibitor that regulates progression from G1 into S phase. Aberrations in cell cycle control are often observed in tumors and might even be necessary in tumor development. Recent reports showed that low p27kip1 expression is associated with poor prognosis in several tumors and leukemia. To investigate the expression

PCAF regulates the stability of the transcriptional regulator and cyclin-dependent kinase inhibitor p27Kip1 [PDF]

open access: yesNucleic Acids Research, 2012
P27(Kip1) (p27) is a member of the Cip/Kip family of cyclin-dependent kinase inhibitors. Recently, a new function of p27 as transcriptional regulator has been reported. It has been shown that p27 regulates the expression of target genes mostly involved in splicing, cell cycle, respiration and translation.

"Nutritional and chemopreventive anti-cancer agents up-regulate expression of p27Kip1, a cyclin-dependent kinase inhibitor, in mouse JB6 epidermal and human MCF7, MDA-MB-321 and AU565 breast cancer cells"

open access: yesCancer Cell International, 2006
Background p27(Kip1) is a cyclin-dependent kinase inhibitor. When up-regulated, p27 inhibits G1-to-S phase transition of the cell cycle. This report addresses the question of whether various nutritional and chemopreventive anti-cancer agents up-regulate ...

p27kip1: a target for tumor therapies?

open access: yesCell Division, 2007
The cyclin kinase inhibitor p27kip1 acts as a potent tumor supressor protein in a variety of human cancers. Its expression levels correlate closely with the overall prognosis of the affected patient and often predict the outcome to different treatment ...

The F-box protein SKP2 mediates androgen control of p27 stability in LNCaP human prostate cancer cells

open access: yesBMC Cell Biology, 2002
Background The cyclin-dependent kinase inhibitor p27 is a putative tumor suppressor that is downregulated in the majority of human prostate cancers. The mechanism of p27 down-regulation in prostate cancers in unknown, but presumably involves increased ...

Oncogenic and Tumor Suppressive Components of the Cell Cycle in Breast Cancer Progression and Prognosis

open access: yesPharmaceutics, 2021
Cancer, a disease of inappropriate cell proliferation, is strongly interconnected with the cell cycle. All cancers consist of an abnormal accumulation of neoplastic cells, which are propagated toward uncontrolled cell division and proliferation in ...

p27 controls autophagic vesicle trafficking in glucose-deprived cells via the regulation of ATAT1-mediated microtubule acetylation

open access: yesCell Death and Disease, 2021
The cyclin-dependent kinase inhibitor p27Kip1 (p27) has been involved in promoting autophagy and survival in conditions of metabolic stress. While the signaling cascade upstream of p27 leading to its cytoplasmic localization and autophagy induction has ...

The protein kinase C inhibitor enzastaurin exhibits antitumor activity against uveal melanoma. [PDF]

open access: yesPLoS ONE, 2012
GNAQ mutations at codon 209 have been recently identified in approximately 50% of uveal melanomas (UM) and are reported to be oncogenic through activating the MAPK/Erk1/2 pathway.

The Role of p27kip1 in the Aggressiveness of Papillary Thyroid Carcinoma: A Clinicopathological Analysis

open access: yesمجلة كلية الطب
Background: Cell-cycle-regulating proteins, including cyclin-dependent kinase inhibitor 1B p27kip1, have been researched in different malignancies, including thyroid carcinoma, and their association with tumor aggressiveness and recurrence has been ...
