BACKGROUND Tumor-associated macrophages (TAMs) are alternatively activated cells induced by interleukin-4 (IL-4)-releasing CD4+ T cells. TAMs promote breast cancer invasion and metastasis; however, the mechanisms underlying these interactions between macrophages and tumor cells that lead to cancer metastasis remain elusive. Previous studies have found(More)
The objective of the present study was to evaluate the capacity of a tissue-engineered bone complex of recombinant human bone morphogenetic protein 2 (rhBMP-2)-mediated dental pulp stem cells (DPSCs) and nano-hydroxyapatite/collagen/poly(L-lactide) (nHAC/PLA) to reconstruct critical-size alveolar bone defects in New Zealand rabbit. Autologous DPSCs were(More)
PURPOSE To evaluate the efficacy and toxicity of induction chemotherapy followed by concurrent chemoradiotherapy (the treatment group) versus concurrent chemoradiotherapy with or without adjuvant chemotherapy (the control group) for locoregionally advanced nasopharyngeal carcinoma. METHODS The search strategy included Pubmed, Embase, the Cochrane Library,(More)
One hundred and two strains of Lactobacillus plantarum, all isolated from traditional dairy products of minority nationalities, were evaluated for in vitro probiotic properties, including acid and bile tolerance, aggregation activity, and antibacterial activity. Of these, 12 strains with a high tolerance to simulated gastric juice (pH 2.5, 3 h of(More)
BACKGROUND Stem-like prostate cancer cells are also called prostate cancer stem cells (PrCSCs). These rare cells are supposed to be highly tumorigenic and to be involved in maintenance of tumor homeostasis and mediation of tumor metastasis. Methods for sorting PrCSCs are mainly based on sorting cells with the marker (CD133(+)/CD44(+)) or side population(More)
Type I collagen was added to the composite chitosan solution in a ratio of 1:2 to build a physical cross-linked self-forming chitosan/collagen/β-GP hydrogel. Osteogenic properties of this novel injectable hydrogel were evaluated. Gelation time was about 8 min which offered enough time for handling a mixture containing cells and the subsequent injection.(More)
To assess its potential neuroprotective effect against ischemia/reperfusion (IR) injury in mice, bicyclol was administered intragastrically once a day for 3 days. After 6h of bicyclol pretreatment on the third day, forebrain ischemia was induced for 1h by bilateral occlusion of the carotid arteries. After different times of reperfusion, the(More)
Radioresistance remains one of the important factors in relapse and metastasis of nasopharyngeal carcinoma. Thus, it is imperative to identify genes involved in radioresistance and explore the underlying biological processes in the development of radioresistance. In this study, we used cDNA microarrays to select(More)
Increasing evidence suggests that low to moderate ethanol ingestion protects against the deleterious effects of subsequent ischemia/reperfusion; however, the underlying mechanism has not been elucidated. In the present study, we showed that expression of the neuronal large-conductance, Ca2+-activated K+ channel (BKCa) α-subunit was upregulated in cultured(More)
The aim of the present study was to investigate the role of autophagy in response to ionizing radiation (IR) in CNE-2 human nasopharyngeal carcinoma cells and to demonstrate the function of poly(ADP-ribose) polymerase-1 (PARP-1) in the regulation of IR-induced autophagy. Microtubule-associated protein 1 light chain 3 (LC3) and poly(ADP-ribose) (PAR) were(More)
