BACKGROUND Hepcidin, a key regulator of iron metabolism, is synthesized by the liver. Hepcidin binds to the iron exporter ferroportin to regulate the release of iron into plasma from macrophages, hepatocytes, and enterocytes. AIM To study hepcidin expression in liver tissue of patients with hepatocellular carcinoma (HCC), chronic hepatitis C (CHC) and(More)
AIM To assess the role of circulating tumor cells (CTCs) and cancer stem cells (CSCs) in hepatitis C virus (HCV)-associated liver disease. METHODS Blood and/or tissue samples were obtained from HCV (genotype 4)-associated hepatocellular carcinoma patients (HCC; n = 120), chronic hepatitis C patients (CH; n = 30) and 33 normal control subjects (n = 33).(More)
BACKGROUND Angiogenesis is an essential process in cancer growth maintenance, and metastasis. Angiopoietin-2 promotes tumor angiogenesis by priming the vasculature and potentiating the effects of cytokines at the front of active neovascularization. Enhanced expression of angiopoietin-2 has been reported in lung cancer tissue. Survivin is one of the(More)
BACKGROUND Prostate cancer (PC) is the most common cancer affecting men, it accounts for 29% of all male cancer and 11% of all male cancer related death. DNA is normally released from an apoptotic source which generates small fragments of cell-free DNA, whereas cancer patients have cell-free circulating DNA that originated from necrosis, autophagy, or(More)
BACKGROUND Ovarian cancer remains a major worldwide health care issue due to the lack of satisfactory diagnostic methods for early detection of the disease. Prior studies on the role of serum cancer antigen 125 (CA125) and human epididymis protein 4 (HE4) in detecting ovarian cancer presented conflicting results. New tools to improve the accuracy of(More)
Plasma DNA integrity index is increased in various malignancies including breast cancer, the most common cancer in women worldwide; early detection is crucial for successful treatment. Current screening methods fail to detect many cases of breast cancer at an early stage. In this study, we evaluated the level of plasma DNA integrity index in 260 females (95(More)
Transforming growth factor-B1 (TGF-β1 )and its coreceptor endoglin (ENG) have been shown to contribute to hepatocellular tumor development and malignant progression. Our aim was to evaluate the serum expression levels of ENG/ TGF-β1 mRNAs and risk of hepatocellular carcinoma in cirrhotic Egyptian patients. Our study included 77 subjects. Real time(More)
Hepatocellular carcinoma (HCC) ranks as the fifth most common malignancy worldwide. Early detection of HCC is difficult due to the lack of reliable markers. We aimed to assess the diagnostic role of annexin A2 (ANXA2) and follistatin as serum markers for HCC patients. This study included 50 patients with confirmed diagnosis of HCC, 30 patients with chronic(More)
BACKGROUND In Egypt, breast cancer is estimated to be the most common cancer among females. It is also a leading cause of cancer-related mortality. Use of circulating cell-free DNA (ccf-DNA) as non-invasive biomarkers is a promising tool for diagnosis and follow-up of breast cancer (BC) patients. OBJECTIVE To assess the role of circulating cell free DNA(More)
