Many anticancer agents as well as ionizing radiation have been shown to induce autophagy which is originally described as a protein recycling process and recently reported to play a crucial role in various disorders. In HCT116 human colon cancer cells, we found that curcumin, a polyphenolic phytochemical extracted from the plant Curcuma longa, markedly(More)
To understand the process and molecular mechanism of cellular aging, we explored novel senescence-associated genes using rat tissues with different age. Using total RNAs from 6 and 24-month old rat tissues, differential display reverse transcriptase polymerase chain reaction (DD RT-PCR) were performed and 12 differentially expressed genes (DEGs) which were(More)
Metformin, the most frequently prescribed anti-diabetic drug, has recently been paid attention as a chemotherapeutic agent. In this study, we demonstrated that metformin decreased the viability of parental as well as cisplatin/taxol-resistant ovarian cancer cells. Its anti-proliferative effect was further demonstrated by dose‑dependent reduction of the(More)
Cinnamaldehyde (CA) has various functional properties, such as anti-cancer, anti-microbial, anti-inflammatory, and anti-oxidant activities. This study examined the intracellular signaling mechanisms of CA on the oxidative stress response in human dental pulp cells (hDPCs). The results showed that CA did not have any cell cytotoxicity or cause morphological(More)
