Gastric-colon cancer is a complex, multi-stage disease involving deregulation of different signaling cascades. Tis study was conducted to determine the extent of apoptosis, angiogenesis, inflammation, and oxidative stress in patients with gastric-colon cancers. Plasma levels of soluble (s) Fas, bcl-2 as antiapoptotic indices; cathepsin D (CD), calpain I and II as proteolytic, apoptotic indices; nitric oxide (NO), lipid peroxides (LPER) ... إقراء المزيد

Worldwide Egypt had the highest prevalence of hepatitis C virus infection. Angiogenesis is a complex process that regulated by many factors, including vascular endothelial growth factor (VEGF). In the liver hepatic satellite cells (HSCs), Kupffer cells, regenerating hepatocytes and existing endothelial cells are responsible for the process of neoangiogenesis and production of vascular endothelial growth factor (VEGF). AIM OF THE ... إقراء المزيد

ABSTRACT Apoptosis and aging are complementary and cooperative processes that reduce cell proliferation and promote resistance to tumor development. Cellular levels of oxidative stress increase during physiological aging and tend to induce apoptosis, thereby influencing cellular and tissue aging and life span. Aim of study: is to determine the relationship between aging and apoptotic indices in the form of s-Fas ... إقراء المزيد

ABSTRACT Leptin is a 16 KDa protein, consists of 167 amino acid residues. It has many functions including angiogenesis. Leptin either induces angiogenesis itself or influences the levels of other angiogenic factors. The aim of the present investigation was to study the effect of leptin on the levels of the angiogenic factors: vascular endothelial growth factor (VEGF) and thymidine phosphorylase ... إقراء المزيد
