Protein kinases play a central role in the regulation of normal and neoplastic growth. A novel approach to evaluating this role is to apply the photoaffinity analogue of adenosine 5'-triphosphate (ATP), 8-azido[gamma-32P]adenosine 5'-triphosphate (8-N3-[gamma-32P]ATP), to extracts obtained from
Butylated hydroxytoluene (BHT) causes transient lung damage in mice, and it can either inhibit or enhance carcinogen induction of tumors in internal organs, such as urethan-induced lung adenomas. Since protein kinase C (Pk-C) may mediate the action of one class of tumor-modulatory agents, the
This study investigated the chemical composition, anticancer, and antimicrobial activities in vitro of the essential oil isolated from the heartwood of Cunninghamia lanceolata var. konishii from Taiwan. The essential oil was isolated using hydrodistillation in a Clevenger-type apparatus, and
(1) Shavings from the Eastern Red Cedar (Juniperus virginiana) were examined for three diverse biological properties, i.e. enzyme induction, procarcinogenicity and insecticidal activity. (2) The ability of a cedar environment to stimulate liver drug-metabolizing enzymes in mice was confirmed by
The present study aimed to examine the chemical composition and biological activity of essential oils extracted from Euphorbia macrorrhiza collected from Northwest China. The major constituents of the essential oils of aerial parts and roots of E. macrorrhiza are acorenone B (16.72% and 25.80%),
BACKGROUND
Drugs used both in classical chemotherapy and the more recent targeted therapy do not have cancer cell specificity and, hence, cause severe systemic side effects. Tumors also develop resistance to such drugs due to heterogeneity of cell types and clonal selection. Several traditional
