Given a passage classify if the passage has a definite objective/aim/goal or not. Output '1' if the passage has a defininte objective/aim/goal and output '0' if the passage does not have a definite objective/aim/goal.

Elevated levels of EMMPRIN/CD147 in cancer tissues have been correlated with tumor progression but the regulation of its expression is not yet understood. Here, the regulation of EMMPRIN expression was investigated in testicular germ cell tumor (TGCTs) cell lines.', 'EMMPRIN expression in seminoma JKT-1 and embryonal carcinoma NT2/D1 cell lines was determined by Western blot, immunofluorescence and qRT-PCR. Membrane vesicles (MVs) secreted from these cells, treated or not with EMMPRIN siRNA, were isolated by differential centrifugations of their conditioned medium. MMP-2 was analyzed by zymography and qRT-PCR.', 'The more aggressive embryonic carcinoma NT2/D1 cells expressed more EMMPRIN mRNA than the seminoma JKT-1 cells, but surprisingly contained less EMMPRIN protein, as determined by immunoblotting and immunostaining. The protein/mRNA discrepancy was not due to accelerated protein degradation in NT2/D1 cells, but by the secretion of EMMPRIN within MVs, as the vesicles released from NT2/D1 contained considerably more EMMPRIN than those released from JKT-1. EMMPRIN-containing MVs obtained from NT2/D1, but not from EMMPRIN-siRNA treated NT2/D1, increased MMP-2 production in fibroblasts to a greater extent than those from JKT-1 cells.

Charcot-Marie-Tooth (CMT) disease is a group of inherited peripheral neuropathies associated with mutations or copy number variations in over 70 genes encoding proteins with fundamental roles in the development and function of Schwann cells and peripheral axons. Here, we used iPSC-derived cells to identify common pathophysiological mechanisms in axonal CMT.', 'iPSC lines from patients with two distinct forms of axonal CMT (CMT2A and CMT2E) were differentiated into spinal cord motor neurons and used to study axonal structure and function and electrophysiological properties in vitro.', 'iPSC-derived motor neurons exhibited gene and protein expression, ultrastructural and electrophysiological features of mature primary spinal cord motor neurons. Cytoskeletal abnormalities were found in neurons from a CMT2E (NEFL) patient and corroborated by a mouse model of the same NEFL point mutation. Abnormalities in mitochondrial trafficking were found in neurons derived from this patient, but were only mildly present in neurons from a CMT2A (MFN2) patient. Novel electrophysiological abnormalities, including reduced action potential threshold and abnormal channel current properties were observed in motor neurons derived from both of these patients.

It is well known that cardiac rehabilitation (CR) including regular exercise training (ET) is cardioprotective with respect to clinical events in patients with acute myocardial infarction (AMI). However, it is not known whether the regular ET may affect coronary restenosis after percutaneous coronary intervention (PCI) with stenting in AMI. The aim of this study was to evaluate the effect of regular ET on a stented coronary segment and its association with inflammatory markers in AMI.', 'Consecutively 74 AMI patients who underwent PCI with implantation of a drug-eluting stent and 9 month follow-up angiography were included. Thirty seven patients who received CR with ET were assigned to the ET group. Another 37 patients who did not participate in ET, of similar age to those of participants, were assigned to the control group. At 9 months, angiographic restenosis measured as in-segment late luminal loss of the stented coronary artery was analyzed via quantitative coronary angiography using CAAS 5.9.', 'There were no significant differences in baseline characteristics including age, sex, body mass index, smoking, DM, hypertension, lipid profile, use of statin, and complete blood cell between two groups. On 9 month follow-up angiography, late luminal loss per stent was significantly smaller in the ET group compared to the control group (0.14 ± 0.57 vs. 0.54 ± 0.88 mm, p=0.02). Maximal oxygen consumption (VO2max) significantly improved in the ET group after 9months (27.9 ± 6.4 vs. 30.8 ± 5.2 mL/kg/min, p<0.001). Increment in high density lipoprotein-cholesterol (HDL-C) was significantly larger in the ET group at 9 months (0.15 ± 0.12 vs. 0.04 ± 0.24 mg/dL, p=0.03).
