Several lines of experimental evidence indicated that mutations in PfCRT could affect FV membrane transport or pH balance; but how it exerts this activity is still being debated.
Moreover, DIM exerted this activity in a dose of 5 μM, which was 6 times lower than that of I3C.
Although the predominant mechanism by which it exerts this activity remains unclear, and in all likelihood involves multiple overlapping mechanisms, functionally it appears primarily to counteract the costimulatory activity of CD28, with which it shares its two ligands (CD80 and CD86).
This suggests that compounds other than gallic acid exert this cytotoxic activity [ 19].
Analysis of the genome sequence revealed a hemolysin, which could exert this cytotoxic activity.
In this scenario, the native HAHB4 protein would be more efficient than the mutant proteins H4WCT and H1WCT in exerting this inhibitory activity.
However, it remains unclear how HDACi exert this cancer cell-selective activity.
TGF-beta1 has been shown to induce autophagy in certain cells but whether and how this action is exerted in muscle and whether this activity relates to TGF-beta1 control of muscle cell differentiation remains unknown.
For practical use of the root-derived materials as novel antibacterial products to proceed, further studies are needed to establish their human safety and whether this activity is exerted in vivo after consumption of A. heterotropoides root extract and its constituents by humans.
For the practical use of L. speciosa leaf-derived preparations as novel anti-HRV products to proceed, further research is needed to establish their human safety and whether this activity is exerted in vivo after consumption of L. speciosa leaf-derived products by humans.
