The regulatory T cells (Treg) play an important role in the tumor tolerance. The methods to regulate the Treg population in cancer-bearing hosts are limited currently. The effect of curcumin on inhibiting cancer has been recognized, but the mechanism remains elusive. This study tests a hypothesis that administration of curcumin down regulates Tregs in lung cancer (LC) patients. In this study, a group of LC patients was treated with curcumin. The peripheral Tregs and T helper (Th) 1 cells were analyzed by flow cytometry...

BACKGROUND: Neovascularization, also known as angiogenesis, is the process of capillary sprouting from pre-existing blood vessels. This physiological process is a hallmark event in normal embryonic development as blood vessels generally supply both oxygen and nutrients to the cells of the body. Any disruption in this process can lead to the development of various chronic diseases, including cancer. In cancer, aberrant angiogenesis plays a prominent role in maintaining sustained tumor growth to malignant phenotypes and promoting metastasis...

Cisplatin is widely used as chemotherapeutic agent for treatment of diverse types of cancer, however, acute kidney injury (AKI) is an important side effect of this treatment. Diverse mechanisms have been involved in cisplatin-induced AKI, such as oxidative stress, apoptosis and mitochondrial damage. On the other hand, curcumin is a polyphenol extracted from the rhizome of Curcuma longa L. Previous studies have shown that curcumin protects against the cisplatin-induced AKI; however, it is unknown whether curcumin can reduce alterations in mitochondrial bioenergetics and dynamic in this model...
