PURPOSE: Global DNA hypomethylation plays an important role in genomic instability and carcinogenesis. The long interspersed nucleotide element-1 (LINE-1) methylation level is a good surrogate marker of the global DNA methylation level. Previously, we demonstrated a strong relationship between LINE-1 hypomethylation and poor prognosis in certain cancers. However, the relationship between the LINE-1 methylation level and the clinical outcome of pancreatic cancer (PC) remains unclear. METHODS: We used a pyrosequencing assay to measure LINE-1 methylation levels in 126 samples of resected PC and evaluated the prognostic value of the LINE-1 methylation level...

L-Glutamate decarboxylase (GAD) transforms L-glutamate into γ-aminobutyric acid (GABA). Corynebacterium glutamicum that expresses exogenous GAD gene(s) can synthesize GABA from its own produced L-glutamate. To enhance GABA production in recombinant C. glutamicum strain SH, metabolic engineering strategies were used to improve the supply of the GABA precursor, L-glutamate. Five new strains were constructed here. First, the ppc gene was coexpressed with two GAD genes (gadB1 and gadB2). Then, the mdh gene was deleted in C...

The molecular mechanisms responsible for the loss of dopaminergic neurons in Parkinson's disease (PD) remain obscure. Loss of function of E3 ubiquitin ligases is associated with mitochondria dysfunction, dysfunction of protein degradation, and α-synuclein aggregation, which are major contributors to neurodegeneration in PD. Recent research has thus focused on E3 ubiquitin ligase glycoprotein 78 (GP78); however, the role of GP78 in PD pathogenesis remains unclear. Notably, cyclin-dependent kinase 5 (CDK5) controls multiple cellular events in postmitotic neurons, and CDK5 activity has been implicated in the pathogenesis of PD...

Zika virus (ZIKV) remained obscure until the recent explosive outbreaks in French Polynesia (2013-2014) and South America (2015-2016). Phylogenetic studies have shown that ZIKV has evolved into African and Asian lineages. The Asian lineage of ZIKV was responsible for the recent epidemics in the Americas. However, the underlying mechanisms through which ZIKV rapidly and explosively spread from Asia to the Americas are unclear. Non-structural protein 1 (NS1) facilitates flavivirus acquisition by mosquitoes from an infected mammalian host and subsequently enhances viral prevalence in mosquitoes...

A self-adjusting, blood vessel-mimicking, multilayered tubular structure with two polymers, poly(ε-caprolactone) (PCL) and poly(dl-lactide-co-glycolide) (PLGA), can keep the shape of the scaffold during biodegradation. The inner (PCL) layer of the tube can expand whereas the outer (PLGA) layers will shrink to maintain the stability of the shape and the inner space of the tubular shape both in vitro and in vivo over months. This approach can be generally useful for making scaffolds that require the maintenance of a defined shape, based on FDA-approved materials...

As a novel class of endogenous non-coding RNAs, circular RNAs (circRNAs) have become a new research hotspot in recent years. The wide distribution of circRNAs in different plant species has been proven. Furthermore, circRNAs show significant tissue-specific expression patterns in plant development and are responsive to a variety of biotic and abiotic stresses, indicating that circRNAs might have important biological functions in plant development. Here, we summarize the current knowledge of plant circRNAs in recent years and discuss views and perspectives on the possible regulatory roles of plant circRNAs, including the function of miRNA sponges, regulating the expression of their parental genes or linear mRNAs, translating into peptides or proteins and responses to different stresses...
