Multidrug resistance is the main obstacle in cancer chemotherapy. Emerging evidence demonstrates the important role of autophagy in cancer cell resistance to chemotherapy. Therefore, autophagy inhibition by natural compounds may be a promising strategy for overcoming drug resistance in liver cancer cells. Here, we found that ADCX, a natural cycloartane triterpenoid extracted from the traditional Chinese medicine (TCM) source Cimicifugae rhizoma (Shengma), impaired autophagic degradation by suppressing lysosomal cathepsin B (CTSB) expression in multidrug-resistant liver cancer HepG2/ADM cells, thereby leading to autophagic flux inhibition...

What is the central question of this study? We investigated the effects of oestrogen and Cimicifuga racemosa on the stellate ganglion, cardiac noradrenaline pathway and Ca(2+) -calmodulin-dependent protein kinase II in ovariectomized rats. What is the main finding and its importance? The right stellate ganglion, but not the left, may be associated with decreased left ventricular noradrenaline content in ovariectomized rats. Oestrogen can reverse all changes caused by ovariectomy. Cimicifuga racemosa did not affect left ventricular noradrenaline, but decreased protein expression of β1 -adrenergic receptor and Ca(2+) -calmodulin-dependent protein kinase II...
