Expression of MIF and c-erbB-2 in endometrial cancer.The aim of the present study was to investigate the expression of c-erbB-2 and macrophage migration inhibitory factor (MIF) in endometrial cancer and to elucidate the significance of the early diagnosis and prognosis of endometrial cancer. The gene copy number of c‑erbB‑2 and MIF was characterized by reverse transcription quantitative polymerase chain reaction and the reactivity was assessed by immunohistochemistry in 70 patients using a polyclonal antibody, and evaluated semiquantitatively according to the percentage of cells demonstrating membranous or diffuse cytoplasmic staining. A correlation between age, tumor stage, grade, myometrial invasion and lymph node metastasis was observed. The mRNA expression of c‑erbB‑2 and MIF was high in endometrial carcinoma. The positive expression rate of MIF protein in normal endometrium, atypical hyperplasia and endometrial carcinoma significantly increased along with the degree of aggravation of the disease by 20 (3/15), 45 (9/20) and 70% (35/50), respectively. The positive expression of MIF and c‑erbB‑2 was highest in endometrial cancer and a significantly higher level of protein was observed in tumors at stage I, stage G1, with a depth of myometrial invasion <0.4 cm and no lymph node metastasis. The protein expression of c‑erbB‑2 in endometrial cancer was higher in tumors at the G2‑3 phase, clinical stage III‑IV, lymph node metastasis, and had no association with the depth of myometrial invasion and age. MIF and c‑erbB‑2 were correlated with the occurrence and the development of endometrial cancer, and thus can be used for the early diagnosis and prognosis of endometrial cancer. The present study laid the foundation for identifying new treatments for endometrial cancer.

Effect of BRCA1 immunohistochemical localizations on prognosis of patients with sporadic breast carcinomas.Our purpose was to investigate the expression pattern of BRCA1 protein in sporadic breast carcinomas, as well as the clinicopathological and prognostic value of its subcellular localizations. Immunohistochemistry was performed on paraffin embedded tissue specimens from 111 sporadic, invasive breast carcinomas to detect the expression of the proteins BRCA1, ER, PR, erbB2, p53 and Ki67. BRCA1 protein was detected in the nuclei and the cytoplasm of the tumor cells. Nuclear BRCA1 immunoreactivity showed no relation with the classic clinicopathological markers and the expression of cerbB2, p53 and Ki67. Reduced expression of nuclear BRCA1 protein was found to exert an independent favorable impact on both the overall and relapse-free (RF) survival of the patients (p=0.019 and p=0.043, respectively). Cytoplasmic BRCA1 was associated with none of the classic histomorphological indices, except from the lymph node metastasis, with which its relation was found to be inverse (p=0.05), prolonging the RF survival of the patients (p=0.05). Our findings suggest that BRCA1 protein depicts different prognostic significance, according to its subcellular distribution. Nuclear detection of the protein was associated with a worse prognosis, while the cytoplasmic one was related to fewer recurrences as a result of fewer lymph node metastases.

The importance of COX-2 expression as prognostic factor in early breast cancer.A number of studies have been carried out, showing that the risk for breast carcinoma is decreased in those using non-steroidal anti-inflammatory drugs (NSAIDs). Increased cyclooxygenase-2 (COX-2) level is considered as a factor indicating poor prognosis and responsible for angiogenesis, increased cellular proliferation, apoptotic defect and aromatase enzyme induction. For this reason the level of COX-2 might have a prognostic and predictive value in breast cancer as well. This question has become the basis of the present study.

The level of phosphorylated Akt predominantly reflects the expressive status of CerbB2 in invasive breast cancer.Although some evidence has been documented on EGFR/PI3K mediation of Akt activation in breast cancers, ILK and DNA-PK have not been investigated so far. The aim of this study was to analyze the expression of phosphorylated Akt (pAkt) in breast cancer, with respect to its upstream regulators. The immunostaining of pAkt (Ser473) in 70 invasive breast cancers revealed that status of CerbB2 could play a major role in Akt phosphorylation, while ILK was also involved in the stimulated level of pAkt. The results would provide an important clue for the activation of Akt and potential targeted therapy in breast cancer.

Antiproliferative activity of daidzein and genistein may be related to ERα/c-erbB-2 expression in human breast cancer cells.In this study, we investigated the antiproliferative activity of the isoflavones daidzein and genistein in three breast cancer cell lines with different patterns of estrogen receptor (ER) and c‑erbB‑2 protein expression (ERα‑positive MCF‑7 cells, c‑erbB‑2‑positive SK‑BR‑3 cells and ERα/c‑erbB‑2‑positive ZR‑75‑1). After treatment at various concentrations (1‑200 µM for 72 h), the effect of daidzein and genistein on the proliferation of different cell types varied; these effects were found to be associated with ERα and c‑erbB‑2 expression. Daidzein and genistein exhibited biphasic effects (stimulatory or inhibitory) on proliferation and ERα expression in MCF‑7 cells. Although 1 µM daidzein significantly stimulated cell growth, ERα expression was unaffected. However, genistein showed marked increases in proliferation and ERα expression after exposure to <10 µM genistein. Notably, the inhibition of cell proliferation by 200 µM genistein was greater compared to that by daidzein at the same concentration. Daidzein and genistein significantly inhibited proliferation of SK‑BR‑3 and ZR‑75‑1 cells in a dose‑dependent manner. In addition, ERα and c‑erbB‑2 expression was reduced by daidzein and genistein in both SK‑BR‑3 and ZR‑75‑1 cells in a dose‑dependent manner. However, the effect of genistein was greater compared to that of daidzein. In conclusion, the isoflavones daidzein and genistein showed anti‑breast cancer activity, which was associated with expression of the ERα and c‑erbB‑2 receptors.

Clinical implications for girdin protein expression in breast cancer.Girdin is highly expressed in breast carcinomas. Suppression of Girdin inhibited breast cancer cell migration. However, the clinical implications of Girdin as a marker are still unclear. Here we examined 80 breast cancer specimens using immunohistochemistry. Overall, positive Girdin staining was 41.25% in all of the cases. Girdin was strongly expressed in tumors of CerbB2-positive breast cancers (p < .05). Cases with both CerbB2- and Girdin-positive expression had a higher histological grade than the others. These findings indicated the closed relationship between breast cancer progression and Girdin expression. Girdin together with CerbB2 might be a new potential marker for breast cancers.

Application of a novel and low cost technique to construct paraffin tissue microarrays out of paraffinised needle biopsy specimens from patients with breast cancer.Paraffin tissue microarrays (TMAs) are a well accepted tool in pathology for high throughput molecular profiling, quality control and clinicopathological trials. No reports on TMAs constructed from paraffinised needle biopsy specimens (PNBSs) derived from patients with breast cancer can be found in the literature. PNBSs are sometimes the only source for tumour characterisation important for treatment.
