Project description:Tadpoles of the anuran species Rana pirica can undergo predator-specific morphological responses. Exposure to a predation threat by larvae of the salamander Hynobius retardatus results in formation of a bulgy body (bulgy morph) with a higher tail. Whereas, dragon fly also induced higher tail tadpole. The tadpoles revert to a normal phenotype upon removal of the larval salamander or dragon fly threat. The objective of the present study was to use Affymetrix Xenopus Genechip to profile gene expression in the tail tissue by different predation threat. Tadpoles of Rana pirica treated with larvae salamander for 8days (S1, S2, S3) or dragon fly for 8days (Y1,Y2, Y3) were analyzed with triplicate. Removal experiments were also treated with predators for 4days and then removed predators from tadpoles (-S1,-S2, -S3) or (-Y1,-Y2,-Y3). Controls were cultured for 8days without predators (C2, C3). Tails from tadpoles after 8days of each treatment were dissected for RNA extraction and gene expression analysis using Affymetrix Xenopus Genechip arrays.

The objective of the present study was to use Affymetrix Xenopus Genechip to profile gene expression in the tail tissue by different predation threat. Tadpoles of Rana pirica treated with larvae salamander for 8days (brainS1, brainS2, brainS3) were analyzed with triplicate. Controls were cultured for 8days without larvae salamander (brainC1,brainC2,brainC3,brainC4,brainC5,brainC6). Brains from tadpoles after 8days of each treatment were dissected for RNA extraction and gene expression analysis using Affymetrix Xenopus Genechip arrays.

Project description:Tadpoles of the anuran species Rana pirica can undergo predator-specific morphological responses. Exposure to a predation threat by larvae of the salamander Hynobius retardatus results in formation of a bulgy body (bulgy morph) with a higher tail. The tadpoles revert to a normal phenotype upon removal of the larval salamander threat. The objective of the present study was to use our own fabricated tadpole Rana pirica cDNA microarray to profile gene expression patterns during the predation threat. Experimental design used to produce control, bulgy morph and reversion type tadpoles for the microarray analysis was as follows. One group of tadpoles was placed with a larval salamander for 4 days to induce formation of the bulgy morph phenotype; the predator was then removed and the tadpoles were allowed to revert to the normal phenotype for 4 days. This group is termed “8 day out tadpoles”. A second group of tadpoles was placed with the predator for the full 8 days. The control group was not exposed to a predator. Tadpoles from the predator induced groups were sampled at 6 hours, 4 days and 8 days, those from the control group at 0 hour, 4 days, and 8 days. The comparative design of the microarray analysis was performed as (Exp 6 hours VS Cont 0 hours), (Exp 4 days VS Cont 4 days), (Exp 8 days VS Cont 8 days), and (Exp 8 days-Out VS Exp 8 days), respectively. These analyses were performed in triplicate with a dye swap experiment. Samples 0hr~8days were as follows. Sample plate (1~3A):Channel 1-Cy5 Experiment,Channel 2-Cy3 Control. Sample plate (1~3B):Channel 1-Cy5 Control, Channel 2-Cy3 Experiment. In case of 8day-out samples were as follows. Sample plate (1~3A):Channel 1-Cy5 8day-out,Channel 2-Cy3 full 8day. Sample plate (1~3B):Channel 1-Cy5 full 8day,Channel 2-Cy3 8day-out.

Project description:Nanoparticles (<100 nm) are engineered to have unique physico-chemical properties compared to their larger counterparts. Nanosilver (nAg) is the most prevalent nanoparticle in consumer products due to its strong antimicrobial action. While nAg toxicity at high concentrations has been well described, the potential for sublethal effects at or below regulatory guidelines is relatively unknown. Amphibian metamorphosis is mediated by thyroid hormone (TH) and can be precociously induced by the addition of exogenous hormone. Low concentrations of nAg have been shown to disrupt TH-dependent responses in cultured premetamorphic Rana catesbeiana tadpole tail fin. The present study examined the effects of exposure to an environmentally relevant concentration (6 µg/L) of either nAg or ionic silver (iAg) on premetamorphic tadpoles in the absence and presence of exogenous TH. Disruption of thyroid hormone-mediated signalling in brain and liver transcriptomes was evaluated using the MAGEX cDNA microarray.
