GM1-ELISA assay indicated that plant LTB protein bound specifically to GM1-ganglioside, suggesting that the LTB subunits formed active pentamers. CONCLUSION The s-ltb gene that was successfully transformated into centella plants by biolistic method has produced a relatively high amount of plant LTB protein in the pentameric quaternary structure that has GM1-ganglioside binding affinity, a receptor on the intestinal epithelial membrane.

Engler, is used in Chinese and Korean medicine to regulate blood sugar levels; however, little is known about its precise effects. In this study, we aimed to measure the composition as well as the antioxidant, and anti-proliferative capacities of A. tabularis. Various extracts were generated using different organic solvents, and in vitro antioxidant activities were evaluated using DPPH free radical-scavenging and reducing power assays. The extracts were also evaluated based on their ability to inhibit lipopolysaccharide (LPS)-induced nitric oxide (NO) production in RAW 264.7 cells. Research shows that the A. tabularis ethyl acetate (EtOAc) extract showed significant antioxidant activity. Additionally, this extract could inhibit the LPS-induced expression of inflammatory mediators and pro-inflammatory cytokines in RAW 264.7 cells, including inducible nitric oxide synthase (iNOS), cyclooxygenase-2 (COX-2), and interleukin-1 beta (IL-1ß). Notably, the A. tabularis EtOAc extract also displayed potent cytotoxic effects against MCF-7 and HeLa cancer cell lines, as determined by MTT assays. Lastly, total phenol and flavonoid content was measured for all extracts, and four flavonoid compounds-catechin, kaempferol
