ABSTRACT

In the past decade, relative proteomic quantification using isobaric labeling technology has developed into a key tool for comparing the expression of proteins in biological samples. Although its multiplexing capacity and flexibility make this a valuable technology for addressing various biological questions, its quantitative accuracy and precision still pose significant challenges to the reliability of its quantification results. Here, we give a detailed overview of the different kinds of isobaric mass tags and the advantages and disadvantages of the isobaric labeling method. We also discuss which precautions should be taken at each step of the isobaric labeling workflow, to obtain reliable quantification results in large-scale quantitative proteomics experiments. In the last section, we discuss the broad applications of the isobaric labeling technology in biological and clinical studies, with an emphasis on thermal proteome profiling and proteogenomics.

ABSTRACT

OBJECTIVE The aim of this study was to evaluate the outcomes of rehabilitation after cochlear implantation in children with malformed inner ear and compare them with a group of congenitally deaf children implantees with a normal inner ear.METHODS 21 children with inner ear malformation were retrospectively studied. The postoperative outcomes of these 21 cases were compared with that of 21 cases with normal inner ear structure. The assessment of all the children included the hearing levels, language ability , categories of auditory performance (CAP) and speech intelligibility rating (SIR) respectively before cochlear implantation, 6 months and 1 year after surgery. The data was analyzed using SPSS 17.0. RESULTS The results of rehabilitation in 9 children with Large Vestibular Aqueduct Syndrome and 6 cases with Mondini abnormality had no significant difference comparing with the control cases. The outcomes of 1case with severe Mondini abnormality and 5 cases with common cavity indicated significant worse than the control cases. CONCLUSION The effect of rehabilitation had no difference between the children with large vestibular aqueduct syndrome and the cases with normal inner structure after cochlear implantation, but was poorer in children with severe Mondini abnormality and common cavity. It was necessary to evaluate the degree of malformation of inner ear structure before cochlear implantation. The hearing abilities have improved quickly 6 months after cochlear implantation. The language abilities will need at least one year to get improved while the SIR need even more time. The development of language functions requires individualized rehabilitation guidance and integrated education.

ABSTRACT

Diabetes mellitus is a complex metabolic disorder characterized by chronic hyperglycemia due to absolute or relative lack of insulin. Though great efforts have been made to investigate the pathogenesis of diabetes, the underlying mechanism behind the development of diabetes and its complications remains unexplored. Cumulative evidence has linked mitochondrial modification to the pathogenesis of diabetes and its complications and they are also observed in various tissues affected by diabetes. Proteomics is an attractive tool for the study of diabetes since it allows researchers to compare normal and diabetic samples by identifying and quantifying the differentially expressed proteins in tissues, cells or organelles. Great progress has already been made in mitochondrial proteomics to elucidate the role of mitochondria in the pathogenesis of diabetes and its complications. Further studies on the changes of mitochondrial protein specifically post-translational modifications during the diabetic state using proteomic tools, would provide more information to better understand diabetes.
