Identification of new type I interferon-stimulated genes and investigation of their involvement in IFN-β activation

Virus infection induces the production of type I interferons (IFNs). IFNs bind to their heterodimeric receptors to initiate downstream cascade of signaling, leading to the up-regulation of interferon-stimulated genes (ISGs). ISGs play very important roles in innate immunity through a variety of mechanisms. Although hundreds of ISGs have been identified, it is commonly recognized...

Idiopathic desmoid-type fibromatosis of the pancreatic head: case report and literature review

Desmoid-type fibromatosis (DTF) is an uncommon nonmetastatic fibrous neoplasm. Sporadic intraperitoneal DTF is rarely described in current literature. We herein report a case of DTF of unknown cause involving the pancreatic head. A 41-year-old man presented with recurrent epigastric pain and weight loss. An abdominal computed tomography scan showed a well-delineated solid cystic...

Resection of a malignant paraganglioma located behind the retrohepatic segment of the inferior vena cava

Background Resection of a retrocaval paraganglioma is technically challenging due to limited tumor accessibility and proximity to the vena cava. Case presentation A large, malignant paraganglioma was found behind the retrohepatic segment of the inferior vena cava of a 60-year-old male. During resection of this rare paraganglioma, the left lateral lobe of the liver, a portion of...

Zinc-Finger Antiviral Protein Inhibits XMRV Infection

Background The zinc-finger antiviral protein (ZAP) is a host factor that specifically inhibits the replication of certain viruses, including Moloney murine leukemia virus (MoMLV), HIV-1, and certain alphaviruses and filoviruses. ZAP binds to specific viral mRNAs and recruits cellular mRNA degradation machinery to degrade the target RNA. The common features of ZAP-responsive RNA...

Discovery of ∼4.0 Ga detrital zircons in the Aermantai ophiolitic mélange, East Junggar, northwest China

The East Junggar is an important part of the Central Asian Orogenic Belt (CAOB). Using in situ zircon dating and Hf isotopic analysis by LA-ICP-MS and MC-ICP-MS, respectively, a detrital zircon of ∼4040 Ma age was found in sedimentary sequences from the Aermantai ophiolitic mélange, East Junggar. This is the oldest age record in the East Junggar terrane, and also marks the first...

Analyses of SELEX-derived ZAP-binding RNA aptamers suggest that the binding specificity is determined by both structure and sequence of the RNA

The zinc-finger antiviral protein (ZAP) is a host factor that specifically inhibits the replication of certain viruses, including murine leukemia virus, Sindbis virus and Ebola virus, by targeting the viral mRNAs for degradation. ZAP directly binds to the target viral mRNA and recruits the cellular RNA degradation machinery to degrade the RNA. No significant sequence similarity...

Mutagenesis analysis of the zinc-finger antiviral protein

Background The zinc-finger antiviral protein (ZAP) specifically inhibits the replication of certain viruses, including murine leukemia virus (MLV), by preventing the accumulation of viral mRNA in the cytoplasm. ZAP directly binds to the viral mRNA through the zinc-finger motifs and recruits the RNA exosome to degrade the target RNA. RNA helicase p72 is required for the optimal...

Undifferentiated embryonal sarcoma of the liver in a middle-aged adult with systemic lupus erythematosus

Adult primary undifferentiated embryonal sarcoma of the liver (UESL) is a rare disease. While the etiology of UESL remains largely unknown, association with systemic inflammatory disorders has been observed. Here, we report a case of UESL in a 46-year-old woman with systemic lupus erythematosus (SLE) and without chronic hepatitis or liver cirrhosis. Systematic review of the...
