Glucose Deprivation Induced by Acarbose and Oncolytic Newcastle Disease Virus Promote Metabolic Oxidative Stress and Cell Death in a Breast Cancer Model.

Cancer cells are distinguished by enhanced glucose uptake and an aerobic glycolysis pathway in which its products support metabolic demands for cancer cell growth and proliferation. Inhibition of aerobic glycolysis is a smart therapeutic approach to target the progression of the cancer cell. We employed acarbose (ACA), a particular alpha-glucosidase inhibitor, to induce glucose deprivation combined with oncolytic Newcastle disease virus (NDV) to enhance antitumor activity.

Glucose deprivation using 2-deoxyglucose and acarbose induce metabolic oxidative stress and apoptosis in female mice bearing breast cancer.

A characteristic of cancer cells is increased glucose uptake and glycolysis for energy production and hydroperoxide detoxification due to mitochondrial dysfunction. Thus, inhibition of glucose uptake and glycolysis represent smart novel therapy. We used 2-deoxyglucose (2DG) as a glycolysis inhibitor and acarbose (ACA), a specific alpha-glucosidase inhibitor, to decrease glucose uptake.

Reproductive fecundity of Iraqi Awassi ewes immunized against synthetic inhibin-α subunit or steroid-free bovine follicular fluid.

Objective: The present study was conducted to investigate the impacts of active and passive immunization against synthetic inhibin and steroid-free bovine follicular fluid, respectively, on reproductive fecundity out of breeding season in Iraqi Awassi ewes.

Methods: Follicular fluid was aspired from mature bovine follicles, treated with activated charcoal, and used for immunization of male rabbits for obtaining steroid free bovine follicular fluid (SFBFF) antiserum. Forty non-pregnant Awassi ewes were allocated into 4 groups (n = 10 each).
