The epithelial mesenchymal transition (EMT) is intimately associated with tumor hypoxia. The present study was conducted to investigate the immunohistochemical relationship between hypoxic and EMT-related molecules in non-small cell lung carcinoma (NSCLC).
Immunohistochemical staining for hypoxia inducible factor (HIF)-1alpha, carbonic anhydrase (CA) IX, TWIST, and E-cadherin proteins was performed in 146 cases of NSCLC (80 cases of adenocarcinoma and 66 cases of squamous cell carcinoma) using tissue microarray blocks.
HIF-1alpha, TWIST, CA IX, and E-cadherin were expressed in 58 (40%), 90 (62%), 82 (56%), and 36 (25%) of 146 NSCLC cases, respectively. TWIST expression was positively correlated with HIF-1alpha expression (p = 0.03) and inversely correlated with E-cadherin expression (p < 0.01). TWIST and CA IX expression were not significantly interrelated, but each showed a relationship with histological tumor grade. However, the expression of these molecules had no significant effect on clinical staging or patient survival.
Although TWIST expression was correlated positively with HIF-1alpha expression and inversely correlated with E-cadherin, HIF-1alpha expression was not associated with E-cadherin expression. However, considering the relationship between HIF-1alpha and TWIST expression, further studies should be performed to demonstrate the role of hypoxia-induced EMT in NSCLC.

AbstractAbstract PDF
Several studies have been conducted on the role of the p63 gene family in non-small cell lung carcinoma (NSCLC). Nevertheless, the role of these genes in the development and progression of NSCLC remains controversial. This study was designed to examine the expression and clinicopathologic significance of the p63 family in NSCLC.
Immunohistochemical staining was performed on 92 cases of NSCLC (47 squamous cell carcinomas [SqCCs] and 45 adenocarcinomas [ACs]) using tissue microarray blocks. The results were analyzed and correlated with clinicopathologic data. RESULTS: The expression of delta Np63 (Delta Np63) was elevated in SqCC (39/47), but not in AC (2/45; p<0.01). Both p63 and Delta Np63 had high expression in 39 SqCCs; p63 and Delta Np63 also had a similar geomorphologic distribution in most positive tumors. The expression of Delta Np63 was correlated with histologic type, gender, pT stage, p53 expression, and p63 expression. pT and pN stages were independent factors in survival (p<0.05, respectively).
The major p63 isoform in NSCLC, Delta Np63, had a strong correlation with p53 and p63, and was exclusively expressed in SqCC. However, our findings suggest that Delta Np63 was not an independent prognostic factor for NSCLC.

AbstractAbstract PDF
Non-small cell carcinoma (NSCC) has become the leading cause of cancer related death around the world. However, its prognostic factors remain poorly defined. Galectin-3 is an apoptosis related protein and its relationship with various cancers is presently the subject of research. This study was performed to investigate galectin-3 expression in NSCC and its value as a prognostic factor. METHODS: We examined the expression of galectin-3 and bcl-2 in surgically resected, lung NSCC, including 61 squamous cell carcinomas and 41 adenocarcinomas. PCNA staining was also performed. RESULTS: Each type of carcinoma showed cytoplasmic positivity in 18 (30.0%) and 25 (61.0%) cases, respectively. Squamous cell carcinoma showed increased galectin-3 expression in better differentiated tumors, whereas adenocarcinoma didn't show any relationship with the degree of differentiation. The cytoplasmic positivity of galectin-3 in both types of carcinoma was associated with poor prognosis. Bcl-2 expression didn't show any significant relationship with overall survival. Galectin-3 and bcl-2 expressions were positively correlated. However, co-expression of both proteins was not related to prognosis. CONCLUSIONS: These results indicate that galectin-3 expression in NSCC warrants attention as a possible prognostic factor.
