The stomach is the most frequent site of extranodal lymphoma and primary gastric lymphoma might be distinguished from the nodal lymphoma by its different pathogenesis and prognosis. Based on the Isaacson's classification, clinico-pathologic reviews of 38 resected primary gastric lymphomas were done. Immunohistochemical stainings for PCNA, B and T cell markers, bcl-2 and p53 were performed. Eigh...

To isolate novel diagnostic markers and therapeutic targets for pancreatic cancer, we earlier did expression profile analysis of pancreatic cancer cells using a genome-wide cDNA microarray combined with microdissection. Among dozens of trans-activated genes in pancreatic cancer cells, this study focused on KIAA0101 whose overexpression in pancreatic cancer cells was validated by immunohistochem...

PURPOSE The aim of this study was to clarify the relationship between the maximum standardized uptake value (maxSUV) and the expression levels of cell-cycle-related molecular biomarkers. PATIENTS AND METHODS Thirty consecutive patients with non-small cell lung cancer (NSCLC) were enrolled in the study. Histologically, the tumors included 23 adenocarcinomas and 7 squamous cell carcinomas. Prot...

The majority of cases liver cancer are discovered late in the disease’s progression, making it third leading cause death globally. Chemotherapy is major treatment choice for advanced stages hepatocellular carcinoma (HCC); however, drug resistance, adverse effects, and high cost problems effective treatment. Isoquercetin (IQ) a dietary flavonoid, which has an anti-proliferative effect against se...

Objectives: Periapical Granulomas (PGs) and Radicular Cysts (RCs), as the most common odontogenic lesions have yet unclear pathogenesis. This study was aimed to compare PCNA and Ki-67 expression in PGs and RCs and evaluate their possible relationship with two lesions. Methods: In this cross-sectional descriptive study, twenty PGs and twenty RCs were evaluated immunohistochemically using an a...

BACKGROUND p21WAF1 is a potent inhibitor of the cell-cycle regulatory cyclin-dependent kinases (Cdks). It acts on Cdks in the G1 and S phases of the cell cycle, and also binds to proliferating cell nuclear antigen (PCNA), blocking DNA replication in vitro. Transcription of p21WAF1 can be induced by the human tumour suppressor protein p53, suggesting that the action of p21WAF1 may be important i...
