Smurf1-mediated RhoA ubiquitination and degradation plays key roles in regulation of cell polarity and protrusive activity. However, how Smurf1 recognizes RhoA is still not clear. Here we report that the C2 domain of Smurf1 is necessary and sufficient for binding RhoA, and therefore is crucial for targeting RhoA for ubiquitination. In contrast, the C2(More)
OBJECTIVE The objective of this study was to investigate the effects of the c-Jun N-terminal kinase (JNK) signaling pathway on rats' acute pancreatitis-associated lung injury (APALI). METHODS Seventy-two Sprague-Dawley rats were randomly divided into 3 groups, namely, the sham operation (SO) group, the severe acute pancreatitis (SAP) group, and the(More)
In Streptococcus mutans, virulence and cariogenicity may be modulated via the two-component regulatory system VicRK. Environmental signals, sensed by VicK, inducing this modulation are still unclear, however, and were investigated in the present study. We found that VicRK displays homology with protein-domains that, in other bacteria, are involved in(More)
UNLABELLED T-helper 17 (Th17) cells play an important role in the pathogenesis of multiple sclerosis (MS), an autoimmune demyelinating disease that affects the CNS. In the present study, MicroRNA sequencing (miRNA-seq) was performed in mouse Th0 and Th17 cells to determine the critical miRNAs that are related to Th17 differentiation. We found that miR-30a(More)
Differentiation of oligodendrocyte precursor cells (OPCs) is a prerequisite for both developmental myelination and adult remyelination in the central nervous system. The molecular mechanisms underlying OPC differentiation remain largely unknown. Here, we show that the thirty-kDa HIV-1 Tat interacting protein (TIP30) is a negative regulator in(More)
ATM- and RAD3-related (ATR)/Chk1 and ataxia-telangiectasia mutated (ATM)/Chk2 signalling pathways play critical roles in the DNA damage response. Here we report that the E3 ubiquitin ligase Smurf1 determines cell apoptosis rates downstream of DNA damage-induced ATR/Chk1 signalling by promoting degradation of RhoB, a small GTPase recognized as tumour(More)
Hepatocellular carcinoma (HCC) is the fifth most common cause of the tumor worldwide, its incidence is increasing year by year. This study aims to investigate the sorting and biological characteristics of side population (SP) cells. Human HCC tissues used were obtained from patients undergoing surgical resection. SP cells were sorted using flow cytometry.(More)
BACKGROUND AND AIMS Refractory chronic pancreatitis has been proposed as a challenge for endoscopists following routine single plastic stenting. However, data on the efficacy and safety of further endoscopic stenting are still controversial. The current systematic review aimed to assess the efficacy and safety of placement of fully covered self-expandable(More)
BACKGROUND/AIMS Pancreatic cancer is one of the most aggressive tumors in mankind. Its aggressiveness is only due to the biological progressive characteristics but also the difficulty for clinical early detection which urges us to find diagnostic tools for early diagnosis. Biomarkers are a developing tool used to measure molecules such as proteins, DNA, or(More)
BACKGROUND/OBJECTIVES Pulmonary apoptosis is an important pathogenic mechanism of acute lung injury induced by many factors. This study aims to investigate whether the caspase inhibitor zVAD-fmk has a protective effect against lung injury in the severe acute pancreatitis model (SAP) in rats. METHODS Seventy-two Sprague-Dawley rats were randomly divided(More)
