-saponins are natural inhibitors of AKT, MCL-1, and BCL2L1 in cervical cancer cells.

Introduction: Scientific research is beginning to prove the connection between claims by African traditional medicine and the natural chemical specifics contained in medicinal plant . Our previous studies showed that two natural saponin fractions (4A3 and 4A4) identified in the plant as triterpenoid glycosides are capable of activating apoptosis on cervical tumor cell lines. Considering this and some critical roles of human papillomavirus (HPV) E6 oncogene on cervical cells, by promoting carcinogenesis and cell survival, it became necessary to investigate the possible pathways for apoptosis transmission.

Molecular-trapping in Emulsion's Monolayer: A New Strategy for Production and Purification of Bioactive Saponins.

Saponins from defatted root-extract of Securidaca longipedunculata were systematically entrapped in emulsion monolayer-barrier and finally recovered in pure form through demulsification. First, their molecules were dispersed in water to engineer a monomolecular film architecture, via self-assembly. Emulsifying with ethyl-ether resulted in swollen micelles and engendered phase-inversion and phase-separation, by disrupting the thermodynamic equilibrium.

Traditional herbal remedies that influence cell adhesion molecule activity.

Many traditional medicines have demonstrated immune activity, however, research has largely neglected their effects on cell adhesion molecules (CAMs). This review reports on extracts from 37 medicinal plant species, similar to or replicating traditional preparations, that up- or downregulate either gene or protein activity of CAMs. The majority of the investigations were in vitro, primarily of the immunoglobulin superfamily of CAMs, specifically intercellular cell adhesion molecule-1 (ICAM-1) and vascular cell adhesion molecule-1 (VCAM-1) and secondarily on the integrin (CD11b or MAC-1) and selectin (E-selectin and P-selectin) families of CAMs.
