Ugh the central retina. Sections were collected in 24well plates, blocked in 5 goat serum in the presence of 0.5 Triton X-100, incubated overnight with monoclonal mouse antiFLAG M2 (Sigma-Aldrich) diluted in blocker, and stained with goat anti-mouse Alexa Fluor 488 secondary antibody (Invitrogen) and 10 mg/ml Hoechst 33342 (Invitrogen) to label nuclei. To examine the eyes of transgenic tadpoles, the entire animal was fixed in 4 paraformaldehyde, cryoprotected in 30 sucrose, and frozen in 100 tissue-freezing medium. 12 mm cross-sections through the eye were collected directly onto glass slides and stained with 2 mg/ml Hoechst to label the nuclei. All samples were mounted with Fluoromount (Electron Microscopy Sciences) under glass coverslips and visualized using a Nikon Eclipse 90i microscope and a C1 confocal scanner controlled by EZ-C1 v 3.10 software (Nikon). Manipulation of images was limited to adjusting the brightness level, image size, and cropping using either EZ-C1 v 3.10 Viewer or Photoshop (Adobe).DNA ConstructsDNA constructs were generated using standard PCR-based subcloning methods. To generate all Xenopus YFP fusion constructs and their point mutants, overhang extension PCR primers were used (primer sequences available upon request). The FLAG tag was appended to full length mouse peripherin’s N-terminus by introducing the sequence into the forward primer. To make the V332A point mutation in mouse peripherin, we utilized the QuikChange II XL kit (Stratagene). All forward and reverse primers were designed to introduce 59-AgeI and 39-NotI sites respectively. PCR products were subcloned into either the XOP5.5 vector [43] for Xenopus transgenesis or pRho2.2 [44] for in vivo electroportation. DNA templates were obtained as follows: IMAGE clones MedChemExpress QAW039 corresponding to Xenopus peripherin (xRDS38), Xenopus rhodopsin, and mouse peripherin were purchased from American Type Culture Collection; YFP was cloned from pDVNTAP-NYFP obtained from the The Dicty Stock Center; HTR1A was obtained from a mouse brain cDNA library (Stratagene). All constructs were confirmed by direct sequencing.Production of Transgenic TadpolesTransgenic Xenopus tadpoles were generated using the restriction enzyme-mediated integration method [45,46] with modifications described in our previous studies [30,47]. In brief, linearized plasmid DNA containing the transgene was mixed with XenopusAuthor ContributionsConceived and designed the experiments: RYS SAB SMG VYA. Performed the experiments: RYS SAB SMG.

Breast cancer is the leading cause of cancer death among women in Europe and North America. Almost 1.4 million women were diagnosed with breast cancer worldwide in 2008 and approximately 459,000 deaths were recorded [1,2]. More than 2.5 million breast cancer survivors live in United States currently, and the number is expected to grow to 3.4 million by 2015 [3]. The National Cancer Institute (NCI) has recognized that prevention is a critical component in minimizing the number of individuals afflicted with cancer [4]. Recent reports suggest that approximately one-third of the most common cancers in western countries can be prevented by eating a healthy, get Fingolimod (hydrochloride) plant-based diet; being physically active; and maintaining a healthy weight [5]. Epidemiologic studies and systematic analysis suggest diets rich in fruits and vegetables are associated with a reduced risk of cancer,in particular cancers of epithelial origin su.Ugh the central retina.
