Perillyl alcohol causes G1 arrest through p15(INK4b) and p21(WAF1/Cip1) induction.

The monoterpene perillyl alcohol (POH) is a naturally occurring compound derived from citrus fruits, mint and herbs. It exhibited chemotherapeutic potential against various malignant tumors in preclinical models and is currently being tested in clinical trials in patients with refractory advanced cancers. POH inhibits cellular proliferation at the G1 phase of the cell cycle in vitro. However, t...

A p53-independent pathway for induction of p21waf1cip1 and concomitant G1 arrest in UV-irradiated human skin fibroblasts.

Largely on the basis of studies using the potent clastogen ionizing radiation, it has been widely assumed that up-regulation of the cyclin-dependent kinase inhibitor p21(waf1cip1) in cultured cells exposed to DNA-damaging agents is contingent upon the presence of functional p53 tumor suppressor protein. Nevertheless, we demonstrate here that the model mutagen 254-nm UV light induces p21(waf1cip...

ZD1839 induces p15INK4b and causes G1 arrest by inhibiting the mitogen-activated protein kinase/extracellular signal-regulated kinase pathway.

Inactivation of the retinoblastoma protein pathway is the most common abnormality in malignant tumors. We therefore tried to detect agents that induce the cyclin-dependent kinase inhibitor p15(INK4b) and found that ZD1839 (gefitinib, Iressa) could up-regulate p15(INK4b) expression. ZD1839 has been shown to inhibit cell cycle progression through inhibition of signaling pathways such as phosphati...

Perillyl alcohol: applications in oncology.

Perillyl alcohol is a monoterpene isolated from the essential oils of lavendin, peppermint, spearmint, cherries, celery seeds, and several other plants. In animal studies it has been shown to regress pancreatic, mammary, and liver tumors, to exhibit possible application as a chemopreventative agent for colon, skin, and lung cancer, and as a chemotherapeutic agent for neuroblastoma, and prostate...

Perillyl alcohol is an angiogenesis inhibitor.

Aberrant angiogenesis is essential for the progression of solid tumors and hematological malignancies. Thus, antiangiogenic therapy is one of the most promising approaches to control cancer. In the present work, we examined the ability of perillyl alcohol (POH), a dietary monoterpene with well-established tumor chemopreventive and chemotherapeutic activity, to interfere with the process of angi...
