Cancer cell metabolism is often characterized by a shift from an oxidative to a glycolytic bioenergetics pathway, a phenomenon known as the warburg effect. Whether the deregulation of miRNAs contributes to the warburg effect remains largely unknown. Here we show that miR-181a expression is increased and thus induces a metabolic shift in colon cancer cells.(More)
Cancer-associated fibroblasts (CAFs) provide critical metabolites for tumor growth and undergo metabolic reprogramming to support glycolysis. However, the molecular mechanisms responsible for this change remain unclear. Here, we report that TGF-β1- or PDGF-induced CAFs switch from oxidative phosphorylation to aerobic glycolysis. We identify downregulation(More)
How TGF-β1-mediated signaling pathways are finely tuned to orchestrate the generation of carcinoma-associated fibroblasts (CAFs) is poorly understood. Here, we demonstrate that miR-21 and the signaling of its target Smad 7 determine TGF-β1-induced CAF formation. In primary cultured fibroblasts, mature miR-21 increases after TGF-β1 treatment, whereas the(More)
C-type lectins are a large family of Ca²⁺-dependent carbohydrate binding proteins which play crucial roles to recognize and eliminate pathogens in innate immunity. In the present study, a novel C-type lectin was identified from Eriocheir sinensis (designated as EsCTL). The full-length cDNA of EsCTL was of 789 bp with an open reading frame of 468 bp encoding(More)
The C1q domain containing (C1qDC) proteins are a family of proteins possessing globular C1q (gC1q) domains, and they rely on this domain to recognize various ligands such as PAMPs, immunoglobulins, ligands on apoptotic cell. In the present study, a novel multi-domain C1qDC protein (CfC1qDC-2) was identified from scallop Chlamys farreri, and its full length(More)
The CYP2E1 protein belongs to the P450 enzymes family and plays an important role in the metabolism of small molecular and organic pollutants. In this study we generated CYP2E1 transgenic plants of Petunia using Agrobacterium rhizogenes K599. PCR analysis confirmed that the regenerated plants contained the CYP2E1 transgene and the rolB gene of the Ri(More)
Gefitinib (Iressa, ZD-1839), a small molecule tyrosine kinase inhibitor (TKI) of the epidermal growth factor receptor (EGFR) pathway, is currently under investigation in clinical trials for the treatment of colorectal cancer (CRC). However, as known, some patients develop resistance to TKIs, and the mechanisms mediating intrinsic resistance to EGFR-TKIs in(More)
C1q proteins serve as pattern recognition receptors and involve in the pathogen recognition and complement pathway activation. In the present study, a novel C1q domain containing protein from Crassostrea gigas (designated CgC1qDC-1) was isolated by liposaccharide-Sepharose 6B affinity chromatography. The coding sequence of CgC1qDC-1 gene was determined by(More)
High-mobility group box 1 (HMGB1) protein, a highly conserved DNA binding protein, plays an important role in maintaining nucleosome structures, transcription, and inflammation. In the present research, a cDNA of 1268 bp for the Zhikong scallop Chlamys farreri HMGB1 (designed as CfHMGB1) was cloned via rapid amplification of cDNA ends (RACE) technique and(More)
