L-securinine is a natural product extracted and isolated from the leaf of dried Securinega suffruticosa. The aim of the present study was to explore the effects of L-securinine on proliferation, and the methylation profile of the dickkopf-related protein 1 (DKK1) gene in human lung cancer cells and

The identification of agents that preferentially kill cancer cells while protecting normal cells offers the potential to overcome toxicities found in many existing chemotherapeutic agents. Because p53 is frequently inactivated in cancer, agents that preferentially kill p53-null cells and protect

OBJECTIVE
To investigate the anti-tumor effects of L-securinine inducing colon cancer SW480 cell autophagy and explore its potential molecular mechanism.
METHODS
MTT method was used to detect the antitumor effect of SW480 cells cultured with L-securinine in vitro. Light and electron microscopy were

BACKGROUND
The Securinega-type alkaloids occur in plants belonging to Euphorbiaceae family. One of the most widely distributed alkaloid of this group is securinine, which was identified next to allosecurinine in Phyllanthus glaucus (leafflower). Recently, some Securinega-type alkaloids have paid

Natural products have been discovered to be valuable sources of antitumor drugs. L-Securinine is a natural product extracted from the leaves or roots of Securinega suffruticosa Pall Rehd. The current study was done to investigate the molecular mechanisms of antitumor effects of L-securinine. The
L-securinine inhibits cell growth and metastasis of human androgen-independent prostate cancer DU145 cells via regulating mitochondrial and AGTR1/MEK/ERK/STAT3/PAX2 apoptotic pathways.

As the defining feature of Acute Myeloid Leukemia (AML) is a maturation arrest, a highly desirable therapeutic strategy is to induce leukemic cell maturation. This therapeutic strategy has the potential of avoiding the significant side effects that occur with the traditional AML therapeutics. We
