OBJECTIVE Annexin A1 (ANXA1) is suggested to have anti-inflammatory function. However, the precise function of ANXA1 has remained unclear. In this study, we therefore examined the potency of ANXA1 in regulating reactive oxygen species (ROS) production and suppressing pro-inflammatory responses in PC12 cells induced by 1-methyl-4-phenylpyridinium (MPP+). MATERIALS AND METHODS In this experimen...

Specific human chromosomal elements enhance the performance of episomal gene-transfer vectors. S/MAR-based episomal vector pEPI-eGFP transfects CD34+ haematopoietic cells, but only transiently. To address this issue we reinforced (1) transgene transcription by replacing the CMV promoter driving eGFP with the EF1/HTLV or SFFV promoters to produce vectors pEPI-EF1/HTLV and pEPI-SFFV, respectively...

Increased leukocyte elastase activity in mice lacking secretory leukocyte protease inhibitor (SLPI) leads to impaired wound healing due to enhanced activity of TGFbeta and perhaps additional mechanisms. Proepithelin (PEPI), an epithelial growth factor, can be converted to epithelins (EPIs) in vivo by unknown mechanisms with unknown consequences. We found that PEPI and EPIs exert opposing activi...

The lantibiotic Pep5 is produced by Staphylococcus epidermidis 5. Pep5 production and producer immunity are associated with the 20-kb plasmid pED503. A 1.3-kb KpnI fragment of pED503, containing the Pep5 structural gene pepA, was subcloned into the Escherichia coli-Staphylococcus shuttle vector pCU1, and the recombinant plasmid pMR2 was transferred to the Pep5- and immunity-negative mutant S. e...

Introduction: The 3D Pretty Easy Parallel Imaging (PEPI) technique, previously presented as a 2D technique [1], is a coil sensitivity based method used for reconstructing arbitrary 3D k-space trajectories. PEPI is an iterative technique that enforces receive b1-field and sampled data consistency in each iteration (eg. [2-4]). The 3D trajectory used is Spiral Projection Imaging (SPI) [3]. Method...

Purpose To determine the pathologic complete response (pCR) rate in estrogen receptor (ER) -positive primary breast cancer triaged to chemotherapy when the protein encoded by the MKI67 gene (Ki67) level was > 10% after 2 to 4 weeks of neoadjuvant aromatase inhibitor (AI) therapy. A second objective was to examine risk of relapse using the Ki67-based Preoperative Endocrine Prognostic Index (PEPI...

The Women's Health Initiative (WHI), the largest prevention study ever funded by the National Institutes of Health, responded promptly to the findings from the Postmenopausal Estrogen/Progestin Interventions (PEPI) study. In this week's Journal of the American Medical Association, PEPI investigators report that a large proportion of women with a uterus who received estrogen developed adenomatou...

In this study the growth of genetically modified Lactobacillus casei LAB6, overexpressing proline iminopeptidase PepI and its capacity to increase free proline was investigated during ripening of Edam cheese. The strain successfully survived 12 weeks of ripening period in cheese. The food-grade plasmid pLEB604, carrying the pepI gene, was stable, and PepI enzyme was active in LAB6 cells isolate...
