Epithelial-mesenchymal transition is an important developmental process, participates in tumor's formation, invasion, and metastasis and has been extensively studied. Recently, endothelial-mesenchymal transition (EndMT), a newly recognized type of cellular transdifferentiation, has been demonstrated to participate in a number of diseases by causing(More)
Both the human pregnane X receptor (hPXR) and constitutive androstane receptor (hCAR) are capable of regulating CYP3A4 and CYP2B6 gene expression. However, the majority of currently identified CYP3A4 and CYP2B6 inducers are confirmed activators of hPXR but not hCAR. To compare these receptors with respect to their chemical selectivities, 16 drugs known to(More)
Phosphoenolpyruvate (PEP) is an important precursor for anaerobic production of succinate and malate. Although inactivating PEP/carbohydrate phosphotransferase systems (PTS) could increase PEP supply, the resulting strain had a low glucose utilization rate. In order to improve anaerobic glucose utilization rate for efficient production of succinate and(More)
BACKGROUND The polyacrylic resin Amberlite IRA-67 is a promising adsorbent for lactic acid extraction from aqueous solution, but little systematic research has been devoted to the separation efficiency of lactic acid under different operating conditions. METHODOLOGY/PRINCIPAL FINDINGS In this paper, we investigated the effects of temperature, resin dose(More)
Plectasin is a defensin-like antimicrobial peptide isolated from a fungus, the saprophytic ascomycete Pseudoplectania nigrella. Plectasin showed marked antibacterial activity in vitro against Gram-positive bacteria, especially Streptococcus pneumoniae, including strains resistant to conventional antibiotics. Plectasin could kill the sensitive strain as(More)
Transcription factor nuclear factor of activated T cells c4 (NFATc4) is the best-characterized target for the development of cardiac hypertrophy. Aberrant microRNA-29 (miR-29) expression is involved in the development of cardiac fibrosis and congestive heart failure. However, whether miR-29 regulates hypertrophic processes is still not clear. In this study,(More)
Telomeres are critical in maintaining chromosome and genomic stability. Arsenic, a human carcinogen as well as an anticancer agent, is known for its clastogenicity. To better understand molecular mechanisms of arsenic actions, we investigated arsenite effects on telomere and telomerase and determined cell growth and apoptosis in HL-60 and HaCaT cells in(More)
In response to stress signals, postnatal cardiomyocytes undergo hypertrophic growth accompanied by activation of a fetal gene program, assembly of sarcomeres, and cellular enlargement. We show that hypertrophic signals stimulate the expression and transcriptional activity of myocardin, a cardiac and smooth muscle-specific coactivator of serum response(More)
Opposite biological effects of arsenic trioxide (As(2)O(3)) and arsacetin on the growth of human gastric cancer MGC-803 cells have been observed. Results show that As(2)O(3) inhibited the growth of MGC-803 cells by triggering apoptosis, whereas arsacetin promoted the cell proliferation and seemed to stimulate the secretion of some growth factors at the same(More)
MicroRNAs (miRNAs) are a class of endogenous, highly conserved, small noncoding RNAs that regulate gene expression post-transcriptionally. Recent studies have demonstrated that miRNAs are aberrantly expressed in the cardiovascular system. The implications of miRNAs in cardiovascular disease have recently been recognized, representing the most rapidly(More)
