cycas guizhouensis/neoplasms

The methanolic extract of Cycas revoluta cone (MECR) was analyzed by GC-MS and UHPLC for metabolite profiling and was evaluated for anti-colon cancer property by using in vitro assays like Cell Viability Assay, Colony Formation Assay, ROS Determination, Flowcytometry, DAPI staining assay, Tunel

Gastric cancer is one of the most common and deadly malignancies worldwide. Despite recent medical progress, the 5-year survival rate of gastric cancer is still unsatisfactory. 5-fluorouracil (5-Fu) is one of the first-line antineoplastic treatments for gastric cancer,

Nowadays, novel pharmacies have been screened from plants. Among them are the peptides, which show multiple biotechnological activities. In this report, a small peptide (Ala-Trp-Lys-Leu-Phe-Asp-Asp-Gly-Val) with a molecular mass of 1,050 Da was purified from Cycas revoluta seeds by using

BACKGROUND Helicobacter pylori (HP) is a gramnegative bacterium and well recognized as being the primary etiological agent responsible for the development of gastritis, dyspepsia, peptic ulcer disease and gastric cancer. In developing countries, a high prevalence of HP infection is associated with

After weaning, groups of rats were fed a semi-purified diet containing fiddlehead greens (the unfuried frond of the ostrich fern Matteuccia struthiopteris), mature bracken fern (Pteridium aquilinum), or cycad meal (Cycas circinalis), or this diet plus aflatoxin B1. The groups fed 1-10% fiddlehead

BACKGROUND Sotetsuflavone is isolated from Cycas revoluta Thunb., which has biological activity against tumors. However, the anti-proliferative effects of sotetsuflavone on A549 cells and its mechanism are not fully elucidated. METHODS This study investigated the mechanisms of growth inhibition,

Changes in colonic faecal microflora, enzymes of colonic energy metabolism, of cell proliferation and lipid profile in the serum and colon were studied in 48 mice exposed to cycas and fed a Nigeria-type diet. The animals were divided into three diet classes of 16 mice per class, and each class of

Senescent human diploid fibroblasts (HDF) contain no detectable cdc2 mRNA or p34cdc2 protein. Similarly, young quiescent HDF have only low levels of cdc2 mRNA and protein. After serum stimulation, quiescent HDF accumulate increasing amounts of cdc2 mRNA and protein and go through DNA synthesis and

OBJECTIVE The seeds of cycads contain cycasin and neocycasin, which belong to the family of cyanogenic glycosides. These glycosides of cycads are considered pseudocyanogenic with little potential to liberate hydrogen cyanide as other cyanogenic glycosides do. This study investigated the clinical

Cdc25 phosphatases are key activators of the eukaryotic cell cycle and compelling anticancer targets because their overexpression has been associated with numerous cancers. However, drug discovery targeting these phosphatases has been hampered by the lack of structural information about how Cdc25s

Cycads, the most primitive of the living gymnosperms, have been used and continue to be used for food and medicinal purposes by many cultures, although toxins must be removed before ingestion. In our quest to identify tropical plants that contain inhibitors of the cytochrome P-450 aromatase and thus
