SUMMARY High-throughput RNA sequencing (RNA-seq) is rapidly emerging as a major quantitative transcriptome profiling platform. Here, we present DEGseq, an R package to identify differentially expressed genes or isoforms for RNA-seq data from different samples. In this package, we integrated three existing methods, and introduced two novel methods based on(More)
The endoplasmic reticulum (ER) is the primary organelle for folding and maturation of secretory and transmembrane proteins. Inability to meet protein-folding demand leads to "ER stress," and activates IRE1α, an ER transmembrane kinase-endoribonuclease (RNase). IRE1α promotes adaptation through splicing Xbp1 mRNA or apoptosis through incompletely understood(More)
Depending on endoplasmic reticulum (ER) stress levels, the ER transmembrane multidomain protein IRE1α promotes either adaptation or apoptosis. Unfolded ER proteins cause IRE1α lumenal domain homo-oligomerization, inducing trans autophosphorylation that further drives homo-oligomerization of its cytosolic kinase/endoribonuclease (RNase) domains to activate(More)
In cells experiencing unrelieved endoplasmic reticulum (ER) stress, the ER transmembrane kinase/endoribonuclease (RNase)-IRE1α-endonucleolytically degrades ER-localized mRNAs to promote apoptosis. Here we find that the ABL family of tyrosine kinases rheostatically enhances IRE1α's enzymatic activities, thereby potentiating ER stress-induced apoptosis.(More)
A compression scheme of defect image based on wavelet analysis is proposed, according to characteristic of MFL (Magnetic Flux Leakage) signal, in which new wavelet base functions are redesigned by adjusting its zeros and apices of the orthogonal function. The functions are used to transform the defect image and all the wavelet coefficients are scaled(More)
BACKGROUND To observe the effects of the minimally invasive removal of an intracerebral hematoma on the glutamate concentration, blood-brain barrier (BBB) permeability and brain water content in the brain tissue surrounding the hematoma and to provide a theoretical basis for minimally invasive removal of intracerebral hematomas. METHODS Thirty rabbits(More)
The objective of this study was to observe the pathophysiological time window of performing minimally invasive procedures for the intracerebral hematoma evacuation. Thirty-six rabbits were randomly placed in either a normal control group (NC group, 6 rabbits), a model control group (MC group, 6 rabbits) or a minimally invasive group (MI group, 24 rabbits).(More)
Under endoplasmic reticulum stress, unfolded protein accumulation leads to activation of the endoplasmic reticulum transmembrane kinase/endoRNase (RNase) IRE1α. IRE1α oligomerizes, autophosphorylates and initiates splicing of XBP1 mRNA, thus triggering the unfolded protein response (UPR). Here we show that IRE1α's kinase-controlled RNase can be regulated in(More)
High-throughput RNA sequencing (RNA-seq) technology provides a revolutionary approach to studying splicing events de novo. However, identifying splice junctions with high sensitivity and specificity remains a challenge. In the present study, we proposed a new tool named SeqSaw to detect splice junctions with or without the canonical GT-AG splicing signal.(More)
BACKGROUND The purpose of this study was to observe changes in motor function using diffusion tensor imaging (DTI) and motor-evoked potential (MEP) in patients with thalamic hematoma treated by minimally invasive procedures. METHODS Forty-three patients with thalamic hematoma were randomized to either a minimally invasive group (MI group) or a medical(More)
