Tau is a microtubule-associated protein (MAP) whose transcript undergoes complex regulated splicing in the mammalian nervous system. Our previous work with exon 6 established that tau shows a unique expression pattern and splicing regulation profile, and that it utilizes alternative splice sites in several human tissues. The mRNAs from these splicing(More)
The regulation of tau protein expression during different stages of cellular differentiation and development as well as its functional role in morphogenesis, neurofibrillary tangle formation, and neurodegeneration have been topics of extensive study but have not been completely clarified yet. Tau undergoes complex regulated splicing in the mammalian nervous(More)
BACKGROUND Human cytomegalovirus (HCMV) encodes microRNAs (miRNAs) that function as post-transcriptional regulators of gene expression during lytic infection in permissive cells. Some miRNAs have been shown to suppress virus replication, which could help HCMV to establish or maintain latent infection. However, HCMV miRNA expression has not been(More)
In this study we describe the identification and characterization of a novel cytosolic protein of the guanine exchange factor (GEF) family. The human cDNA corresponds to predicted human protein FLJ00128/FLJ10357 located on chromosome 14q11.2. The deduced protein sequence contains in its C-terminus a RhoGEF domain followed by a pleckstrin domain. Its(More)
Recognition of human cytomegalovirus (HCMV) DNA by the cytosolic sensor cGAS initiates STING-dependent innate antiviral responses. HCMV can antagonize host immune responses to promote latency infection. However, it is unknown whether and how HCMV targets the cGAS-STING axis for immune evasion. Here we identified the HCMV tegument protein UL82 as a negative(More)
UNLABELLED Congenital human cytomegalovirus (HCMV) infection is a leading cause of birth defects, primarily manifesting as neurological disorders. HCMV infection alters expression of cellular microRNAs (miRs) and induces cell cycle arrest, which in turn modifies the cellular environment to favor virus replication. Previous observations found that HCMV(More)
UNLABELLED After infection, human cytomegalovirus (HCMV) persists for life. Primary infections and reactivation of latent virus can both result in congenital infection, a leading cause of central nervous system birth defects. We previously reported long-term HCMV infection in the T98G glioblastoma cell line (1). HCMV infection has been further characterized(More)
Immunofluorescence assay (IFA) is one of the most frequently used methods in the biological sciences and clinic diagnosis, but it is expensive and time-consuming. To overcome these limitations, we developed a faster and more cost-effective IFA (f-IFA) by modifying the standard IFA, and applied this method to track the progression of human cytomegalovirus(More)
Human cytomegalovirus (HCMV) is the leading infectious cause of birth defects, and may lead to severe or lethal diseases in immunocompromised individuals. Several HCMV strains have been identified and widely applied in research, but no isolate from China has been characterized. In the present study, we isolated, characterized and sequenced the first Chinese(More)
