our findings suggested that miR-222 may promote the progression of polycystic ovary syndrome by targeting p27 Kip1.
These results demonstrated that JSK could trigger cell cycle arrest at the G2/M phase and apoptosis in A549 and H460 cells, which was likely mediated via the p53/p21WAF1/CIP1 and p27KIP1 pathways. Overall, the results indicated that JSK may be used as an anticancer agent for the treatment of nonsmall cell lung cancer (NSCLC)
Study found that PSMD2 was markedly upregulated in breast cancer. High PSMD2 expression was significantly correlated with poor prognosis. PSMD2 knockdown inhibited cell proliferation and arrested cell cycle at G0/G1 phase in vitro, as well as suppressed tumor growth in vivo. Mechanically, PSMD2 physically interacted with p21 and p27 and mediated their ubiquitin-proteasome degradation with the cooperation of USP14.

Study shows that Cdk2/cyclin A-bound p27 samples lowly-populated conformations that provide access to the BCR-ABL and Src kinases promoting intra-assembly phosphorylation of p27 on distal T187. Even when tightly bound to Cdk2/cyclin A, intrinsic flexibility enables p27 to integrate and process signaling inputs, and generate outputs including altered Cdk2 activity, p27 stability, and, ultimately, cell cycle progression.
HP plays an important role in the development and progression of GC through silencing of CDH1, RUNX3, p21WAF and p27 expression
Rapamycin treatment increased the level of the p27(KIP1) cyclin-dependent kinase inhibitor, and rapamycin-induced ciliogenesis was abrogated in p27(KIP1)-depleted cells. These results indicate that mTORC1 inactivation induces ciliogenesis through p27(KIP1) upregulation, but not through autophagy.
we firstly demonstrate that BCRC-3 is down-regulated in BC tissues and cell lines for the first time. BCRC-3 is capable of functioning as ceRNA for miR-182-5p to regulate the expression of p27.
Our findings demonstrate that circYAP1 functions as a tumor suppressor in GC cells by targeting the miR-367-5p/p27 (Kip1) axis and may provide a prognostic indicator of survival in GC patients.
P27 expression is regulated by ARHGAP17 in cervical cancer.ARHGAP17 elevated P27 expression level through inhibiting PI3K/AKT signaling pathway.
MUC-1, CK7, and c-p27 immunostaining can be used as the predictive markers for esophageal cancer progression from Barrett's esophagus.
High KIP1 expression is associated with acute lymphoblastic leukemia.
c-Myc was demonstrated to drive OVAAL transcription, indicating a positive feedback loop between c-Myc and OVAAL in controlling tumor growth. OVAAL contributes to the survival of cancer cells through dual mechanisms controlling RAF/MEK/ERK signaling and p27-mediated cell senescence.
VEGF, COX-2, and p27 may be important biological markers that determine the angiogenic and lymphangiogenic potentials of papillary thyroid carcinoma, particularly between the follicular and classic variants.

the activation of Rac1 due to the cell-cell contact plays a critical role in the transcriptional up-regulation of p27Kip1 in vascular endothelial cells.
Findings indicate that p27Kip1 is central for the decreased proliferation at lower temperature, since p27Kip1 KO mouse embryonic fibroblasts (MEFs) hardly increased their doubling time in cold conditions, whereas wild-type MEFs significantly delayed proliferation in response to cold stress.
defective p27-phospho-S10 modifies endothelial behavior and promotes aneurysm formation via COX-2 activation.
Our results reveal both major pathways of p27(Kip1) degradation are required for the accelerated Burkitt lymphoma (BL) development driven by LMP2A in our BL model.
The data characterize mitochondrial p27 as a common denominator that improves mitochondria-dependent processes and define an increase in mitochondrial p27 as a new mode of action of caffeine.
after irradiation, loss of p27 is associated to accumulation of residual DNA damage and increased number of mitotic aberration. We show that p27 expression is necessary to preserve genomic integrity and for correct recognition and clearing-out of aberrant cells.
Although expressed in all retinal cell types, p27 is required to maintain the quiescence of specific cell types including bipolar cells, Muller glia, and cones while it is dispensable for preventing cell cycle reentry in other cell types
Findings demonstrate functional interplay between a transcriptional regulator and p27(kip1) to mediate neuroprogenitor cell cycle exit, as well as to promote radial migration through a molecular mechanism consistent with suppression of RhoA signaling.

This study demonstrates that LMP2A uses the role of MYC in the cell cycle, particularly in the p27(kip1) degradation process, to accelerate lymphomagenesis in vivo.
Study reports that p27 normally exerts a negative feedback on p21 expression: p27 directly represses the expression of the transcription factor Pitx2 which in turn maintains decreased p21 levels. Consequently, in cells lacking p27, de-repression of Pitx2 causes the up-regulation of p21 showing a new mechanism by which p27 regulates cell cycle progression by transcriptionally regulating the expression of Pitx2 and p21.

Fbxo7-deficient immature thymocytes failed to undergo expansion in the thymus due to a lack of Cdk6 activity, while mature T cells showed enhanced proliferative capacity upon T-cell receptor engagement due to reduced p27 levels.

Knockout of p27 enhances arterial collateralization in response to hindlimb ischemia through enlargement of a new collateral pathway.
This gene encodes a cyclin-dependent kinase inhibitor, which shares a limited similarity with CDK inhibitor CDKN1A/p21. The encoded protein binds to and prevents the activation of cyclin E-CDK2 or cyclin D-CDK4 complexes, and thus controls the cell cycle progression at G1. The degradation of this protein, which is triggered by its CDK dependent phosphorylation and subsequent ubiquitination by SCF complexes, is required for the cellular transition from quiescence to the proliferative state.
