The present invention describes the use of angiotensin-(1-7) peptide as an anti-cancer therapeutic. Thus, in one embodiment, the present invention comprises a composition to inhibit the growth of cancer cells in an individual comprising a pharmaceutically effective amount of an agonist for the angiotensin-(1-7) receptor to inhibit cancer cell growth or proliferation. Application of a pharmaceutically effective amount of angiotensin-(1-7) or angiotensin-(1-7) receptor agonist is associated with an increase in the expression of genes involved in tumor suppression, apoptosis, and/or cell cycle inhibition, and a decrease the expression of known oncogenes, protein kinases, and/or cell cycle progression genes. Cancers treated using the methods and compositions described herein include cancers having an angiotensin-(1-7) receptor, including, but not limited to, breast and lung cancer.
The present invention provides a device for modifying an atmosphere in proximity to the device, the device comprising a sachet comprising a semipermeable material, and a composition including a mixture of acetylsalicylic acid and sodium bicarbonate contained within a cavity of the sachet. The invention further provides methods for modifying an atmosphere comprising placing a mixture of a carboxylic acid and a base in the atmosphere, wherein the atmosphere has a sufficient level of water vapor such that, upon contact of the water vapor with the mixture, carbon dioxide is produced.
A method and means for enhancing the inner environment of a package containing perishable merchandise include taking a closable package containing perishable merchandise and placing in the package a multi-layered sheet including a plurality of layers comprised of moisture absorbing materials to absorb any residual moisture emanating from the perishable merchandise. The multi-layered sheet includes a quantity of CO
