BACKGROUND We previously demonstrated the autophagy-inducing activity in the crude extract of areca nut (ANE) and its 30-100 kDa fraction (ANE 30-100 K). This study aimed to analyze whether chronic ANE and ANE 30-100 K stimulations lead to higher stress resistance and autophagic activity in oral

Autophagy can be either tumor promotive or suppressive. We previously identified an autophagy-inducing activity in the 30-100 kDa fraction of areca-nut-extract (ANE 30-100K) and showed that several tumor cells subjected to chronic ANE 30-100K stimulation (CAS) exhibited higher

BACKGROUND Oral submucous fibrosis (OSF) is a premalignant and fibrosing disease, which is closely associated with the habit of chewing areca nut. Panax notoginseng Buck F. H. Chen is an often used antifibrotic and antitumor agent. To treat areca nut-induced OSF, we have developed a chewable tablet,

BACKGROUND Overexpression or activation of c-Jun has been implicated in the pathogenesis of several types of cancer. Treatment of oral cells with areca nut extract in culture can increase c-Jun proto-oncogene mRNA levels. The purpose of this study was to investigate the possible role of c-Jun

Areca nut extract demonstrated apoptosis-inducing mechanism by increased caspase-3 activities on oral squamous cell carcinoma.

Background: Oral squamous cell carcinoma is a neoplasm of keratinocyte cells of oral mucosa epithelium that can potentially spread through lymphatic tissue or blood vessel. Although areca nut is one of the plants with a risk of inducing that cancer, areca nut is believed to have high

BACKGROUND Epidermal growth factor receptor (EGFR)-targeted therapy has been extensively assessed in human cancer treatment. We appraised the possible role of tyrosine kinase inhibitors (TKIs) in areca quid (AQ)-associated oral cavity squamous cell carcinomas (OSCCs) by examining EGFR protein

Stimulation of MMP-9 of oral epithelial cells by areca nut extract is related to TGF-β/Smad2-dependent and -independent pathways and prevented by betel leaf extract, hydroxychavicol and melatonin.

There are 200-600 million betel quid (BQ) chewers in the world. BQ increases oral cancer risk. Matrix metalloproteinase-9 (MMP-9) is responsible for matrix degradation, cancer invasion and metastasis. Whether areca nut extract (ANE), a BQ component, stimulates MMP-9 secretion, and the
