Parthenolide reduces metastasis by inhibition of vimentin expression and induces apoptosis by suppression elongation factor α - 1 expression.

Background: Use of pharmaceutical agent for breast cancer chemotherapy is an interesting method that induces cells death by different way, such as apoptosis. Parthenolide is the main compound in feverfew that has been used to cure migraine and rheumatoid arthritis for long time. Parthenolide has been predominately investigated as inducer of apoptosis in human cancer cells.

Persian shallot, Allium hirtifolium Boiss, induced apoptosis in human hepatocellular carcinoma cells.

This study investigated the potential of Persian shallot extract as an anticancer agent in HepG2 tumor cell line, an in vitro human hepatoma cancer model system. The inhibitory effect of Persian shallot on the growth of HepG2 cells was measured by MTT assay. To explore the underlying mechanism of cell growth inhibition of Persian shallot, the activity of Persian shallot in inducing apoptosis was investigated through the detection of annexin V signal by flow cytometry and expression of some apoptosis related genes such p21, p53, puma, caspase-8 family-Bcl-2 proteins like bid, bim, bcl-2 and bax were measured by real-time PCR in HepG2 cells.

Antibacterial activity of Pseudonocardia sp. JB05, a rare salty soil actinomycete against Staphylococcus aureus.

Staphylococcus aureus is a Gram-positive bacterium that causes many harmful and life-threatening diseases. Some strains of this bacterium are resistant to available antibiotics. This study was designed to evaluate the ability of indigenous actinomycetes to produce antibacterial compounds against S.
