We found that the extract effectively blocked cell cycle progression by inhibiting the expression of cyclin D1 and E in A549 cells. | |||||||||||||||
| |||||||||||||||
|
Since it was reported that lymphomas with a mantle cell lymphoma morphology and CD5 expression, but without cyclin D1 overexpression, exist in about 10% of mantle cell lymphoma cases, we diagnosed his disease as mantle cell lymphoma. | |||||||||||||||

|
Salicylate significantly inhibited serum-induced progression from G1 to S phase, cellular proliferation, and the expression of cyclin D1. | |||||||||||||||
| |||||||||||||||
|
Cyclin D1 expression was determined by Western blot analysis and prostaglandin E2 expression by enzyme-linked immunosorbent assay. | |||||||||||||||

|
Overexpression of cyclin D1 has been observed in many human tumors and is likely to promote cell proliferation and differentiation by shortening the G1/S transition.129,130,139 Amplification of the cyclin D1 gene has been detected in about 15% of breast cancers, while overexpression of cyclin D1 at mRNA and protein levels is seen in up to 50% of primary breast cancers, mostly ER-positive and well-differentiated tumors.129131 A representative picture of cyclin D1 overexpression in human breast cancer is shown in Figure 2b. | |||||||||||||||

|
High cyclin D1a expression inversely correlated with the Ki67 proliferation marker, but was not associated with clinical outcome. | |||||||||||||||

Interpretation is further complicated by suggestions that under some circumstances, cyclin D1 overexpression may worsen clinical outcome by conferring resistance to endocrine treatments.149,150 Consistent with this possibility, one small clinical study suggested that the duration of response to tamoxifen was significantly longer in ER-positive patients with low cyclin D1 than those with high cyclin D1.150 Resolution of these issues must await more detailed analysis of cyclin D1 expression and patient outcomes in the context of prospective randomized clinical trials. | |||||||||||||||

|
Indeed, MMTV-cyclin D2 mice show increased proliferation of mammary glands in pregnant females, but alveolar differentiation is partially or completely inhibited.157 In one report, cyclin D3 was overexpressed in breast cancers, but there are limited data on its relationship to the phenotype of breast cancer and prognosis of patients.158 Keyomarsi et al showed that the absence of cyclin D1 or cyclin D3 protein expression was associated with improved disease-specific and overall survival, but the correlations were less striking than those for cyclin E.159
Cyclin E | |||||||||||||||

Cyclin D2 is more ubiquitously expressed in tissues than cyclin D1. | |||||||||||||||
| |||||||||||||||
|
did not influence cyclinD1 nor p53 levels, as shown by immunoblotting (Fig. 3C). | |||||||||||||||
| |||||||||||||||
|
This case suggests that the overexpression of CD117, p53 protein, cyclin D1, and HER2/neu might be involved in the progression from lower-grade ACC to solid-type ACC and HGA. | |||||||||||||||
| |||||||||||||||
|
However, parameters involved with key features such as cyclin-D and PSA expression were relatively well constrained (CV50%). | |||||||||||||||
| |||||||||||||||
|
The relationship between overexpression of cyclin D1 and breast cancer outcome has been controversial, with studies reporting both positive and negative findings.141143 Subgroup analyses within relatively few patients have also hampered definitive conclusions. | |||||||||||||||
| |||||||||||||||
|
The utility of cyclin D1 as a predictor of breast cancer prognosis is controversial, but cyclin D1b overexpression is associated with poor prognosis. | |||||||||||||||
| |||||||||||||||

|
In spite of these limitations, there appears to be a relationship between cyclin D1 gene amplification and poor disease outcome in ER-positive patients.144146 In contrast, cyclin D1 protein expression is associated with a good prognosis in some studies,141,147 potentially as a consequence of its positive relationship with ER expression and negative relationship with RB mutations. | |||||||||||||||
| |||||||||||||||
|
However, the cyclin D1b protein was upregulated in breast cancer, independent of cyclin D1a levels, and exhibited heterogeneous levels in breast cancer specimens. | |||||||||||||||
