The aim of this study is to explore the underlying mechanism on berberine-induced Cyclin D1 degradation in human hepatic carcinoma. We observed that berberine could suppress both in vitro and in vivo expression of Cyclin D1 in hepatoma cells. Berberine exhibits dose- and time-dependent inhibition on Cyclin D1 expression in human hepatoma cell HepG2. Berberine increases the phosphorylation of Cy...
The Wnt pathway regulates cell proliferation, mobility and differentiation. Among the many Wnt target genes is CCND1 which codes for cyclin D1. Cyclin D1, in complex with cdk4 and cdk6, regulates G1/S phase transition during cell cycle. Independently of CDK, cyclin D1 also regulates the migration of macrophages. Here we analyzed the effects of cyclin D1 on the migration of cancer cell lines usi...
EBNA3C, one of the Epstein-Barr virus (EBV)-encoded latent antigens, is essential for primary B-cell transformation. Cyclin D1, a key regulator of G1 to S phase progression, is tightly associated and aberrantly expressed in numerous human cancers. Previously, EBNA3C was shown to bind to Cyclin D1 in vitro along with Cyclin A and Cyclin E. In the present study, we provide evidence which demonstr...
lates with the maturational stage of these cells. We have studied cyclin D1 expression in the inner ear. Besides its well known function in the cell cycle control, cyclin D1 has also been implicated in other cellular processes like cell death, cellular differentiation and cancer. During early embryogenesis cyclin D1 is widely expressed in the developing sensory epithelia, but it becomes downreg...

Both cyclin D1 and estrogens have an essential role in regulating proliferation of breast epithelial cells. We show here a novel role for cyclin D1 in growth regulation of estrogen-responsive tissues by potentiating transcription of estrogen receptor-regulated genes. Cyclin D1 mediates this activation independent of complex formation to a CDK partner. Cyclin D1 activates estrogen receptor-media...
GL331 is a novel podophyllotoxin-derived compound. In this study, GL331 induced human lung adenocarcinoma cell line CL1-5 growth arrest before death during the initial 24-h incubation period. We found that GL331 had no inhibitory effect on the expression of cyclins E, A, B1, CDK 4, and CDK 2; instead, its cell growth-inhibitory effect was partly attributable to an early down-regulation of cycli...
Androgen receptor (AR) activity is required for prostate growth, differentiation, and secretion. Deregulation of AR activity results in inappropriate mitogenic signaling and is thought to contribute both to the initiation and progression of prostate cancers. Cyclin D1 functions as a strong AR corepressor by directly interacting with and inhibiting receptor activity. However, the extent to which...
Induction chemotherapy is likely to be effective for biologically distinct subgroups of patients with cancer with biomarker detection. To investigate the prognostic and predictive values of cyclin D1 expression in patients with oral squamous cell carcinoma (OSCC) who were treated in a prospective, randomized, phase III trial evaluating standard treatment with surgery and postoperative radiother...
Following acute hepatic injury, the metabolic capacity of the liver is altered during the process of compensatory hepatocyte proliferation by undefined mechanisms. In this study, we examined the regulation of de novo lipogenesis by cyclin D1, a key mediator of hepatocyte cell cycle progression. In primary hepatocytes, cyclin D1 significantly impaired lipogenesis in response to glucose stimulati...
