Oxidative stress is the major contributor to acetaminophen (AAP)-caused liver damage. It promotes mitochondrial oxidative stress and collapses the mitochondrial membrane potential to cause cell death. We have previously shown that a polyphenol extract of Hibiscus sabdariffa L. (HPE) potentiated the antioxidative effect. We further examined in this study the(More)
Antrodia camphorata is used in folk medicine for the treatment of inflammation syndromes and liver-related diseases in Taiwan. The goal of this study was to evaluate the efficacy of the mycelial extract of A. camphorata (ACE) for the treatment of systemic lupus erythematosus (SLE) in SLE-prone NZB/W F1 mice. After antibodies against double-stranded DNA(More)
cDNAs specifically expressed at the basidiome stage were isolated by using PCR-selected cDNA subtraction in order to study gene regulation during porous-hymenium basidiomatal formation in Antrodia cinnamomea. blastx results suggested that most of the expressed sequence tags (52.4-69.5%) had no significant protein homology to genes from other published(More)
Antrodia cinnamomea, a precious, host-specific brown-rot fungus that has been used as a folk medicine in Taiwan for centuries is known to have diverse bioactive compounds with potent pharmaceutical activity. In this study, different fermentation states of A. cinnamomea (wild-type fruiting bodies and liquid cultured mycelium) were sequenced using the(More)
Antrodia cinnamomea is a scarce, epiphyte, host-specific, brown-rot fungus that produces diverse bioactive compounds with potent biological activity. Natural wild-type fruiting bodies of A. cinnamomea are rare and highly valued, but their artificial culture poses challenges. Triterpenoids are a group of secondary metabolites that contribute to the(More)
Medicinal mushroom Antrodia cinnamomea is a higher Basidiomycetes endemic to Taiwan, where it is commonly used as a traditional folk medicine. It is well known for its multiple biologic activities and its potential for commercial development. Here, ten full lengths of cytochrome P450 (CYP) genes (ac-1 to ac-10) from A. cinnamomea were cloned and identified.(More)
Cinnamomum osmophloeum is a commercially important tree species in Taiwan, which has numerous chemotypes with various secondary metabolite profiles. The linalool chemotype is important because it generates pure S-(+)-linalool with high yield. In the present study, the linalool synthase (LIS) genes were isolated from different provenances of C. osmophloeum.(More)
Mulberry has favorable antioxidant ability. Menopause is a major cause of osteoporosis in women, and it is partially associated with oxidative stress. Here, mulberry water extract (MWE) was fed to ovariectomic (OVX) rats to explore the potential effect of MWE on osteoporosis. The results revealed that plasma alkaline phosphatase (ALP) significantly(More)
Taiwania (Taiwania cryptomerioides Hayata), native to Taiwan, is one of the “living fossils” from the Tertiary period of the Cenozoic era. To isolate genes involved in wood formation and biochemical synthesis from this tree, 436 randomly selected clones from a cDNA library derived from seedling were sequenced and analyzed firstly. Contig analysis of these(More)
Methyltransferases play crucial roles in many cellular processes, and various regulatory mechanisms have evolved to control their activities. For methyltransferases involved in biosynthetic pathways, regulation via feedback inhibition is a commonly employed strategy to prevent excessive accumulation of the pathways' end products. To date, no biosynthetic(More)
