The genus Artemisia is one of the most abundant groups of medicinal plants in the Asteraceae family. Based on the theoretical basis of the pharmacophylogeny, the phylogenetic analysis, association analysis and other methods were used to systematically sort out the genetic relationships, properties, tastes, chemical constituents, and traditional efficacy of Mongolian medicines of genus Artemisia(MMA). The correlation and regularity were discussed.

In recent years, liver fibrosis has become a major global problem, and the incidence rate and mortality are increasing year by year. However, there are currently no approved treatments.

However, the underlying mechanisms remain unclear. Here, based on the fact that the combination of 2 μM A plus 4 μM Se possessed a stronger anti-leukemic effect on APL cell line NB4 as compared with each individual, we employed iTRAQ-based quantitative proteomics to identify a total of 58 proteins that were differentially expressed after treatment with As/Se combination rather than As or Se alone, the majority of which were involved in spliceosome pathway.

Our previous study has shown that the combination therapy of arsenite (As) and selenite (Se) induces apoptosis in APL NB4 cells, although the mechanisms are not clear. Here, we demonstrate that the interaction between heat shock protein 90 (Hsp90)-mediated UPR and autophagy is the core module for As/Se combination-induced apoptosis.

There are many similarities in their morphology, traditional curative effect, and modern pharmacological treatment. In this study, we built distribution maps of and in China and a phylogenetic tree of common medicinal plants in Asteraceae.

The increasing role of intestinal flora in CAC may represent a new approach to improving CAC treatment. Berberine can reduce colorectal adenoma recurrence and inhibit colorectal carcinogenesis.

F undergoes self-immolative cleavage when exposed to GSTP1-1 in live cancer cells, facilitating the visualization of molecule release and distribution, as well as confirming the autophagy-induced apoptosis.

Due to the difficulty of directly and unambiguously measuring its levels, most of the beneficial effects associated with ONOO in vivo remain controversial or poorly characterized. Recently, optical imaging has served as a powerful noninvasive approach to studying ONOO in living systems.

Herein, sixteen mutants were designed by substituting these residues with Ala. Mutants G60A, G80A, I101A, N155A and L160A were completely inactive.
View Article and Find Full Text PDFArsenic (III) methyltransferase (AS3MT) catalyzes the process of arsenic methylation. Each arsenite (iAs(3+)) binds to three cysteine residues, methylarsenite (MMA(3+)) binds to two, and dimethylarsenite (DMA(3+)) binds to one. However, only two As-binding sites (Cys156 and Cys206) have been confirmed on human AS3MT (hAS3MT).
