Background Gene encoding optineurin (OPTN) is a causative gene for glaucoma and amyotrophic lateral sclerosis,with a more expression in retina.Our previous study isolated OPTN-interacting proteins and identified that the gene encode the basic leucine zipper (bZIP) transcription factor neural retina leucine (NRL) zipper,a causative gene for retinitis pigmentosa,and further study demonstrated the interaction between OPTN and NRL proteins in nuclei of cultured HeLaS3 cells.Objective This study was to determine the protein binding site of OPTN necessary for NRL binding.Methods A deletion series of OPTN-expression plasmids were constructed and co-expressed with hemagglutinin (HA)-tagged NRL in HeLaS3 cells,respectively.The cytoplasmic and nuclear fractions were used to perform co-immunoprecipitate (CoIP) and Western blot with anti-tag antibodies.Results In the nuclear fractions of cells transfected with the del1 st,del2nd or del3rd plasmid,a band of coimmunoprecipitated HA-labelled NRL (HA-NRL) was detected.However,the del4th plasmid did not produce a band.The NRL band was not found in cytoplasmic fractions from transfected cells with any of the deletion plasmids or with the whole-length OPTN plasmid.Conclusions The protein binding site of OPTN necessary for NRL binding is determined.This result demonstrates the binding of Flag-OPTN and HA-NRL in HeLaS3 cells.A series of partial-deletion OPTN plasmids demonstrated that the tail region (423-577 amino acids) of OPTN was necessary for binding with NRL.

The clinical features, electroneurophysiology, neuroimaging and gene characteristics of one case of early adult-onset dentatorubral-pallidoluysian atrophy (DRPLA) with an onset of epilepsy were reported. The female patient had the onset manifestation of epilepsy. Whereafter, she progressively developed marked cerebellar ataxia, mental retardation and choreic movement. Electroencephalography showed that there were multiple complex slow waves in the whole brain cortex. Magnetic resonance imaging showed the patient had marked atrophies in the cerebral cortex, brainstem and cerebellum. Atrophin-1 gene detection revealed that the numbers of CAG repeats were 15/65 (the patient) and 14/54 (her father) respectively. Her father had no clinical manifestations until now. The mother and brother were normal. DRPLA has diverse clinical presentation,heterogeneous phenotypic spectrum, early adult-onset DRPLA is rare, and the specific gene detection can be helpful for a definitive diagnosis.

The effects of fenofibrate on plasminogen activator inhibitor-1 (PAI-1) expression in human umbilical endothelial cell-derived transformed cell line--ECV 304 cells were investigated. ECV 304 cells were incubated with different concentrations of fenofibrate (0, 10, 50, 100 micromol/L) for 24 h. PAI-1 mRNA and protein was detected by reverse transcription-polymerase chain reaction (RT-PCR) and Western blot respectively. PAI-1 antigenic content of endothelial cells was measured by using ELISA. Fenofibrate could inhibit the PAI-1 mRNA and protein expression and reduce PAI-1 antigenic content dependently. After treatment with fenofibrate (10 micromol/L), the expression levels of PAI-1 mRNA and protein were 0.65 +/- 0.05 and 0.96 +/- 0.11 respectively, significantly lower than in the control group (0.78 +/- 0.03 and 1.21 +/- 0.15, respectively, P<0.05). PAI-1 antigenic contents (24.52 +/- 8.39) in ECV304 cells treated with 10 micromol/L fenofibrate were significantly lower than those in the control group (6.98 +/- 5.12, P<0.05). It was concluded that fenofibrate inhibited the expression of PAI-1 mRNA in ECV304 cells, and reduce the protein expression and the antigenic content of PAI-1, suggesting that fenofibrate may have an antiatherosclerotic effect on endothelial cells by PAI-1 pathway.
