- Background: Nup88 is overexpressed in a number of types of carcinomas and is associated with myometrial invasion, but its exact expression pattern in endometrial cancer and premalignant lesions is unknown. Aims: To evaluate the role of Nup88 in endometrial cancers and atypical endometrial hyperplasia and its clinicopathological significance. Methods: Nup88 expression was examined by immunohistochemistry in samples from 104 endometrial cancers, 21 atypical endometrial hyperplasia lesions, and 40 normal endometria. All samples were from patients who underwent surgery at the First Hospital of Hebei Medical University (Shijiazhuang, China) between April 2006 and December 2009. Nup88 expression was compared between the groups and associations were assessed between Nup88 and clinicopathological characteristics of the subjects. Results: Nup88 expression in cancer (76% of samples) and atypical hyperplasia (91%) was significantly higher compared to normal endometrium (33%, both P < 0.001), but there was no significant difference between endometrial cancer and atypical hyperplasia (P = 0.237). The expression of Nup88 increased significantly with increasing exposure time to estrogen (P = 0.033). Conclusions: Nup88 may be related to the occurrence of endometrial cancers and premalignant lesions. Nup88 might be a useful biomarker for pre-malignant lesions and early-stage endometrial cancer.

- Particularly interesting new cysteine-histidine rich protein (PINCH), as a newly discovered protein of LIM family members, may play a role in signal transduction of integrin and growth factor, and involved in the incidence and development of tumors. PINCH protein is overexpressed in tumor-associated stroma of several types of tumors. However, there is no study of the PINCH in esophageal cancer, therefore we investigated PINCH expression in esophageal squamous cell carcinomas and its clinicopathogical significance in the patients. PINCH expression was immunohistochemically examined in 20 normal esophageal samples and 64 esophageal squamous cell carcinomas. The results showed that PINCH expression in the stroma of cancers was heterogeneous, and its positive rate (56%) was higher than that of normal esophageal mucosa (5%, p<0.0001). The stronger staining was observed at the invasive edge of tumor when compared to the inner area of tumor. The rate of positive PINCH (90%) in the cases with lymph node metastasis was higher than that (41%) in the cases without metastasis (p<0.0001). PINCH expression was not correlated with patients’ gender, age, tumor location, size and differentiation (p>0.05). The results suggest that PINCH protein may be a marker of tumor associated-stroma involving tumor development, and predicting the ability of invasion and metastasis of esophageal squamous cell carcinoma.
