Tanshinone IIA (Tan IIA) is a major compound extracted from a traditional herbal medicine Salvia miltiorrhiza BUNGE, which is used to treat cardiovascular diseases, cerebrovascular diseases and postmenopausal syndrome. It has also been shown to possess anti-inflammatory activity. Since Tan IIA has a similar structure to that of 17beta-estradiol (E(2)), the(More)
To precisely manipulate the intracellular delivery of pleiotropic curcumin, this work reports two types of acid-responsive polymer-curcumin conjugates with different structures. One or two amphiphilic poly(ethylene glycol)-co-poly(lactic acid) (PEG-PLA) copolymer(s) were linked to curcumin via pH-liable hydrazone, producing a linear or phospholipid-like(More)
It is known that human benign prostatic hyperplasia might arise from an estrogen/androgen (E/T) imbalance. We studied the response of castrated rat prostate to different ratios of circulating E/T. The castrated male Wistar rats were randomly injected with E/T at different ratios for 4 weeks. The prostates of E/T (1:100) group showed a distinct prostatic(More)
Transient transformation is simpler, more efficient and economical in analyzing protein subcellular localization than stable transformation. Fluorescent fusion proteins were often used in transient transformation to follow the in vivo behavior of proteins. Onion epidermis, which has large, living and transparent cells in a monolayer, is suitable to(More)
Tomato Verticillium wilt is a soil-borne vascular disease caused by the necrotrophic fungus Verticillium dahliae. Although some understanding of plant defense mechanisms against V. dahliae infection has been gained for incompatible interactions, including identification of inducible resistant genes and defense signaling pathways, the genes and signaling(More)
Accumulating evidence suggests an enhancing effect of estrogens on prostate cancer (PCa) progression. Matrix metalloproteinase 2 (MMP2), which plays an important role in prostate cancer invasion, is mainly expressed in prostatic stromal cells (PrSC). Here we show that estradiol (E(2)) treatment up-regulates MMP2 production in PrSC, which promotes PCa cell(More)
Epigenetic factors may modulate chronic Hepatitis B viral infection by affecting virion gene transcription. The aim of this study was to compare the methylation status of the intrahepatic covalently closed circular DNA (cccDNA) CpG island 2 and HBV replication capability. HBV cccDNA was extracted from liver biopsies of 55 HBsAg-positive patients with(More)
Nitrogen deposition on temperate steppe was monitored from November 2011 to October 2012 in Taipusi County, Inner Mongolia. The dry deposition of gaseous nitrogen compounds was calculated based on online-monitored atmospheric concentrations of NH3 and NO2 and dry deposition velocity simulated by CMAQ model. The wet deposition, dry deposition of particle,(More)
