A lectin with highly potent inhibitory activity toward breast cancer cells from edible tubers of Dioscorea opposita cv. nagaimo.

Only registered users can translate articles

A 70-kDa galactose-specific lectin was purified from the tubers of Dioscorea opposita cv. nagaimo. The purification involved three chromatographic steps: anion exchange chromatography on a Q-Sepharose column, FPLC-anion exchange chromatography on a Mono Q column, and FPLC-gel filtration on a

Downregulation of CircRNA CDR1as specifically triggered low-dose Diosbulbin-B induced gastric cancer cell death by regulating miR-7-5p/REGγ axis.

Only registered users can translate articles

Diosbulbin-B (DB) was the main compound of Dioscorea bulbifera L, which was widely used for cancer treatment in Asia. However, the hepatotoxicity induced by high-dose DB seriously limited its possibility using for gastric cancer (GC) treatment in clinic. In this study, we found that DB inhibited GC

Diosgenyl Saponin Inducing Endoplasmic Reticulum Stress and Mitochondria-Mediated Apoptotic Pathways in Liver Cancer Cells.

Only registered users can translate articles

Diosgenin and diosgenyl saponins as the major bioactive compounds isolated from dietary fenugreek seeds, yam roots, etc. possessed strong antitumor effects. To understand their detailed antitumor mechanisms, a fluorophore-appended derivative of diosgenin [Glc/CNHphth-diosgenin (GND)] was

Estrogen activities and the cellular effects of natural progesterone from wild yam extract in mcf-7 human breast cancer cells.

Only registered users can translate articles

We studied the estrogenic activity and cellular effect of wild yam extract in MCF-7 human breast cancer cells. The extract increased the activity of the progesterone receptor and pS2 genes at the mRNA levels in human breast cancer MCF-7 cells, although the effects were not as prominent as those of

Evaluation of wild yam (Dioscorea villosa) root extract as a potential epigenetic agent in breast cancer cells.

Only registered users can translate articles

The present study was designed to evaluate the efficacy of wild yam root extract (WYRE) as a potential demethylating agent using two breast cancer cell lines, MCF-7 (estrogen receptor positive; ER(+)) and MDA-MB-231 (Estrogen receptor negative; ER(-)), and a methylated gene, GATA3, as a potential

Deltonin induces apoptosis in MDA‑MB‑231 human breast cancer cells via reactive oxygen species‑mediated mitochondrial dysfunction and ERK/AKT signaling pathways.

Only registered users can translate articles

Deltonin, a steroidal saponin isolated from Dioscorea zingiberensis Wright, exhibits high cytotoxic activity in cancer cells. In the present study, the effects of deltonin on cell proliferation and apoptosis were evaluated in the MDA‑MB‑231 human breast carcinoma cell line. Following treatment with

Cytotoxic saponin against lung cancer cells from Dioscorea birmanica Prain & Burkill.

OBJECTIVE To investigate the cytotoxic activity against lung cancer cells of Dioscorea birmanica Prain & Burkill extract and its compounds. METHODS Cytotoxic activity was tested against two types of lung cancer cell line (A549 and CORL-23), one type of normal lung cell (MRC-5) by sulforhodamine B

Dioscorea japonica extract down-regulates prostaglandin E2 synthetic pathway and induces apoptosis in lung cancer cells.

Only registered users can translate articles

Prostaglandin E2 plays a role in an array of pathophysiological responses, including inflammation, carcinogenesis and so on. Prostaglandin E2 is synthesized from arachidonic acid by the enzymes cyclooxygenase and prostaglandin E synthase. In some pathological conditions, the isozymes

Gene expression profiling and pathway analysis data in MCF-7 and MDA-MB-231 human breast cancer cell lines treated with dioscin.

Only registered users can translate articles

Microarray technology (Human OneArray microarray, phylanxbiotech.com) was used to compare gene expression profiles of non-invasive MCF-7 and invasive MDA-MB-231 breast cancer cells exposed to dioscin (DS), a steroidal saponin isolated from the roots of wild yam, (Dioscorea villosa). Initially the

Traditional Chinese medicine syndrome-related herbal prescriptions in treatment of malignant tumors.

OBJECTIVE To investigate the distribution characteristics of TCM syndromes and the related herbal prescriptions for malignant tumors (MT). METHODS A clinical database of the TCM syndromes and the herbal prescriptions in treatment of 136 MT patients were established. The data were then analyzed using

Polysaccharides from Dioscorea batatas induce tumor necrosis factor-alpha secretion via Toll-like receptor 4-mediated protein kinase signaling pathways.

Only registered users can translate articles

The bioactive polysaccharides (named ZPF1) from yam ( Dioscorea batatas) were chemically determined, suggesting repeating beta-1,4-mannan as mainly having a feature of acetylation on C2-OH and C3-OH, around 28%. The ZPF1 participated in the stimulation of murine wild-type macrophages predominantly

Cytotoxicity of Elaoephorbia drupifera and other Cameroonian medicinal plants against drug sensitive and multidrug resistant cancer cells.

Only registered users can translate articles

BACKGROUND Multidrug resistance (MDR) is a major hurdle for cancer treatment worldwide and accounts for chemotherapy failure in over 90% of patients with metastatic cancer. Evidence of the cytotoxicity of Cameroonian plants against cancer cell lines including MDR phenotypes is been intensively and

Evaluation of the safety profiles of estrogenic Chinese herbal medicines in breast cancer.

Only registered users can translate articles

An increasing number of breast cancer patients in Asian countries has been found to consume dietary supplements including phytoestrogen-rich Chinese herbal medicines with an expectation to alleviate the side effects of conventional cancer therapies.The

In vitro cytotoxic activity of Thai medicinal plants used traditionally to treat cancer.

Only registered users can translate articles

The SRB assay was used to test cytotoxicity against three human cancer cell lines and one normal cell line of 11 Thai medicinal plant species used by traditional doctors in treating cancer patients. The extraction procedures used were similar to those practised by Thai traditional doctors (ethanolic

Evaluation of the clinical value of the newly identified urine biomarker HIST1H4K for diagnosis and prognosis of prostate cancer in Bulgarian patients.

Only registered users can translate articles

OBJECTIVE Searching for diagnostic and prognostic biomarkers for prostate cancer (PC) is main public health priority. DNA methylation in body fluids is a stable, easily detectable and promising PC biomarker. The major advantages of urine-based assays are their noninvasive nature and the ability to
