Project description:Two month-old male Wistar rats received either resveratrol (10 mg/kg) plus N-acetylcysteine (400 mg/kg) or vehicle during 5 consecutive days. The second day of treatment, a concentrated solution of kanamycin and furosemide was placed on the round window of the right ears of rats receiving treatment or vehicle. Hearing was assessed by recording auditory brainstem responses before and 5, 16 and 23 days after starting the treatment with resveratrol and N-acetylcysteine. Cochlear samples were taken at the end of the treatment (5 days) and once the treatment had been suspended (23 days) to study cochlear cytoarchitecture and the evolution of the expression of oxidative stress, antioxidant defense and inflammation genes by using PCR arrays and RT-qPCR. qPCR gene expression profiling. Cochlea samples from 3-6 animals per group were analised. The expression of genes related to oxidative stress, antioxidant defense, and inflammation was studied at 5 and 23 days after the initiation of the 5 days treatment with resveratrol plus NAC.

Project description:Inflammation is a key component of pathological angiogenesis. Here we induce cornea neovascularisation using sutures placed into the cornea, and sutures are removed to induce a regression phase. We used whole transcriptome microarray to monitor gene expression profies of several genes
Project description:In order to establish a rat embryonic stem cell transcriptome, mRNA from rESC cell line DAc8, the first male germline competent rat ESC line to be described and the first to be used to generate a knockout rat model was characterized using RNA sequencing (RNA-seq) analysis.
