High MCM6 Expression as a Potential Prognostic Marker in Clear-cell Renal Cell Carcinoma.

Aim: Minichromosome maintenance (MCM) proteins are involved in initiation of DNA replication and cell-cycle progression. Loss of MCM function results in genomic instability and causes carcinogenesis. Among MCM genes, the role and prognostic value of MCM6 expression in clear-cell renal cell carcinoma (ccRCC) has not been elucidated.

High expression of QSOX1 is associated with tumor invasiveness and high grades groups in prostate cancer.

Prostate cancer is the most common malignancy in men, and biologically shows highly heterogeneous clinical outcomes, despite early detection. Therefore, the identification of novel molecular markers that are associated with biological aggressiveness is very important for prostatic cancer clinical outcome predictions and treatment choices. Here, we investigate quiescin sulfhydryl oxidase 1 (QSOX1) expression and evaluate its clinicopathological significance and prognostic impact in prostate cancers, with immunohistochemistry on tissue microarrays.

Effect of laminin 332 on motility and invasion in bladder cancer.

We examined the correlation between laminin 332 and malignancy in bladder cancer patients, and, using a strain of invasive bladder cancer cells, determined whether laminin 332 causes bladder cancer motility and invasion. To investigate the correlation between laminin 332 g2 distribution and patient outcome, we performed a semiquantitative immunohistochemical analysis of 35 paraffin-embedded samples using the antibody D4B5, which is specific for the laminin 5 γ2 chain. To evaluate the role of laminin 332 in NBT-II cell motility and invasion, we used a scratch assay and the Boyden chamber chemoinvasion system.
