Arginine-conjugated albumin microspheres inhibits proliferation and migration in lung cancer cells.

TL;DRAbstract

Arginine is one of the essential amino acid involved in numerous biosynthetic pathways that significantly influence tumor growth. It has been demonstrated that arginine is effective to inhibit proliferation of cancer cells when an appropriate dose is applied. Generally, induction of cell death requires high concentration of arginine while low concentration of arginine facilitates cell proliferation. In addition to the apoptosis induced by metabolism of arginine, it has also been reported that in an ideal solution environment, arginine may assemble into arginine clusters to kill cancer cells. Therefore, to make the arginine an effective anticancer agent, arginine/albumin microspheres were designed and synthesized to provide a localized high concentration of arginine on tumor sites. In addition, the arginine/albumin mesospheres (AAMS) are also expected to provide an arginine-rich surface on microspheres, which is similar to the arginine cluster, to effectively inhibit tumor growth.
