Abstract

An efficient and convenient method, three-dimensional (3-D) cell bioreactor coupled with high performance liquid chromatography-mass spectrometry was developed for affinity screening and analysis of multiple bioactive components from herbal medicines. Cancer cells were cultured on a porous scaffold to form a 3-D cell bioreactor. After interacting with live and fixed cells, the HPLC fingerprinting chromatograms of herbal medicine extract were compared to evaluate the binding properties of herbal components on cells. Model anticancer drugs (paclitaxel and resveratrol) and non-anticancer drugs (ketoprofen and penicillin G) were chosen to investigate the feasibility. When cell-drug interaction time was 30 min, the binding degrees of paclitaxel and resveratrol (each 15 μg/ml) were 82.2±7.2% and 66.1±4.1%, and for ketoprofen and penicillin G (each 15 μg/ml) were less than 3%. This method was used to screen bioactive components from Polygonum cillinerve (Nakai) Ohwi (PCO) extract, and the binding degrees of two main components in PCO extract (10 μg/ml), aristolochic acid A and aristolochic acid B, were 63.0±5.1% and 18.8±0.9%, respectively. These results demonstrated that this method was highly specific, efficient and convenient for a...Continue Reading

Cancer Metabolism

In order for cancer cells to maintain rapid, uncontrolled cell proliferation, they must acquire a source of energy. Cancer cells acquire metabolic energy from their surrounding environment and utilize the host cell nutrients to do so. Here is the latest research on cancer metabolism.
