Monocyte chemoattractant protein-1 in dogs affected with neoplasia or inflammation.

Monocyte chemoattractant protein-1 (MCP-1) is a member of the C-C family chemokines, which mobilizes monocytes from bone marrow to the site of inflammation. To evaluate the clinical utility of canine MCP-1 as a blood test item, we measured serum MCP-1 concentrations in normal and ill dogs. Reference interval of canine MCP-1 was established as 115.

A case of pancreatic solid-pseudopapillary neoplasm with marked ossification.

A cystic lesion of the pancreas was detected in a 25-year-old asymptomatic woman during a company medical checkup. Abdominal computed tomography (CT) revealed an ossified lesion in the pancreatic body, and the patient was referred to us for further management. Abdominal ultrasound and endoscopic ultrasound showed a hypoechoic mass with a large ossific focus, measuring 25 mm in the pancreatic body.

I(2020)T leucine-rich repeat kinase 2, the causative mutant molecule of familial Parkinson's disease, has a higher intracellular degradation rate than the wild-type molecule.

Leucine-rich repeat kinase 2 (LRRK2) has been identified as the causal gene for autosomal dominant familial Parkinson's disease (PD), although the mechanism of neurodegeneration involving the mutant LRRK2 molecules remains unknown. In the present study, we found that the protein level of transfected I(2020)T mutant LRRK2 was significantly lower than that of wild-type and G(2019)S mutant LRRK2, although the intracellular localization of the I(2020)T and wild-type molecules did not differ. Pulse-chase experiments proved that the I(2020)T LRRK2 molecule has a higher degradation rate than wild-type or G(2019)S LRRK2.
