BACKGROUND While carcinogenesis in Sporadic Colorectal Cancer (SCC) has been thoroughly studied, less is known about Ulcerative Colitis associated Colorectal Cancer (UCC). This study aimed to identify and validate differentially expressed proteins between clinical samples of SCC and UCC to elucidate new insights of UCC/SCC carcinogenesis and progression. RESULTS Multiplex-fluorescence two-dim...

The aim of this study was to evaluate dysregulation of gene expression associated with the cellular stress response in a patient with a post-"warning stroke" depressive disorder confirmed by the presence of a neurophysiological neuromarker through the use of quantitative EEG and event-related potentials. The patient was tested for seven genes associated with the stress reaction: HSPA1A, HSPB1, ...

The mechanisms underlying mitochondrial impairment in the failing heart are not yet clearly defined. In the present study, we examined the involvement of changes in small heat shock proteins (HSPs) such as HSPB1, HSPB5 and HSPB8 in mitochondrial dysfunction of the failing heart. Hemodynamic parameters of rats with myocardial infarction at the 2nd and 8th weeks (2W- and 8W-) after coronary arter...

The human small heat shock proteins (HSPBs) form a family of molecular chaperones comprising ten members (HSPB1-HSPB10), whose functions span from protein quality control to cytoskeletal dynamics and cell death control. Mutations in HSPBs can lead to human disease and particularly point mutations in HSPB1 and HSPB8 are known to lead to peripheral neuropathies. Recently, a missense mutation (R7S...

The highly pathogenic porcine reproductive and respiratory syndrome virus (HP-PRRSV) is still a serious threat to the swine industry. However, the pathogenic mechanism of HP-PRRSV remains unclear. We infected host porcine alveolar macrophages (PAMs) with the virulent HuN4 strain and the attenuated HuN4-F112 strain and then utilized fluorescent two-dimensional difference gel electrophoresis (2D-...

BACKGROUND AND OBJECTIVE Protein expression in colon and rectal cancer (CRC) and paired normal tissues was examined by two-dimensional gel electrophoresis (2-DE) to identify differentially expressed proteins. MATERIALS AND METHODS Five fresh colorectal cancer and paired adjacent normal tissues were obtained and differentially expressed protein spots were determined using PDQuest software, wit...

The aim of this study was to evaluate adrenergic responses in the peripheral blood of trained road cyclists at rest, at maximal intensity of incremental bicycle exercise test, and during 15 minutes of recovery, as well as the relationship between them. Competitive male road cyclists, in the pre-competitive phase of a season, mean age 21.7 ± 6.4 years, and BMI 20.7 ± 0.8 kg·m(-2), performed an i...

The birth of novel genes, including their cell-specific transcriptional control, is a major source of evolutionary innovation. The lens-preferred proteins, crystallins (vertebrates: α- and β/γ-crystallins), provide a gateway to study eye evolution. Diversity of crystallins was thought to originate from convergent evolution through multiple, independent formation of Pax6/PaxB-binding sites withi...

We herein describe a Japanese family with distal hereditary motor neuropathy carrying a K141Q mutation of small heat shock protein HSPB1. Two patients among them had late onset disease (older than 50 years). The muscles of the distal legs were weak and atrophic. Sensory and autonomic dysfunction were not seen. Even eight years after onset, one patient could still walk without support. A nerve c...
