Background: The induction of bystander effect via ionizing radiation has been well proven. However, few studies have investigated the bystander effect following non-ionizing radiation, such as ultrasound waves. Here, the bystander effect after different sonication times on human melanoma cell line (A375), is evaluated by assessing cell viability and apoptosis. Materials and Methods: The cells w...

Anisaldehyde (4-methoxybenzaldehyde), previously reported as a tyrosinase inhibitor, did not inhibit melanogenesis in cultured B16-F10 melanoma cells but rather enhanced it. This adverse effect of anisaldehyde was accompanied by melanocytotoxicity in a dose-dependent manner up to 2 mM. The melanin content per cell at 1 mM was increased 5-fold compared to control and morphological observations s...

A new indole alkaloid named bufobutarginine (1), along with three known bufotenines, namely, serotonin (2), bufotenidine (3), and bufotenine (4), were isolated from the water extract of toad venom. Their structures were elucidated by spectral methods. This is the first time that arginine has been found to be involved in the biosynthesis of bufotenines in parotid of toad. The cytotoxic activitie...

Endothelin-1 (ET-1) inhibited serum-dependent growth of asynchronized A375 human melanoma cells, and the growth inhibitory effect was markedly enhanced when ET-1 was applied to the cells synchronized at G1/S boundary by double thymidine blocks. Flow cytometric analysis revealed that ET-1 did not inhibit the cell cycle progression after the release of the block but caused a significant increase ...

Background: Skin cancer is the most prevalent type of cancer and melanoma is the deadliest kind of skin cancer in the world. Due to enhanced induction of apoptosis and ROS levels, low-level lasers can be utilized to destroy skin cancer cells. Lasers are used to treat some skin lesions. Vitamin A is beneficial in the prevention and treatment of skin cancer. Vitamin A inhibits the pathway of canc...
