Antitumor activity of bovine lactoferrin and its derived peptides against HepG2 liver cancer cells and Jurkat leukemia cells.

Liver cancer and leukemia are the fourth and first causes, respectively, of cancer death in children and adults worldwide. Moreover, cancer treatments, although beneficial, remain expensive, invasive, toxic, and affect the patient's quality of life. Therefore, new anticancer agents are needed to improve existing agents.

Effect of pregnancy and diabetes on vascular receptors for angiotensin II.

Both gestation and diabetes mellitus (DM) are conditions associated with an increased participation of renin-angiotensin system (RAS) as well as with changes in the vascular response to angiotensin II (Ang II). We sought to establish the impact of gestational diabetes mellitus (GDM) on Ang II- induced vasoconstriction and its correlation with the expression of angiotensin II receptors (AT(1)R, AT(2) R). Female Wistar rats, virgin, or on day 3 after mating, received randomly streptozotocin (STZ) 60 mg/kgor saline ip.
