Cadmium was a kind of silver-white heavy metal. Like chromium, cadmium was combined with oxygen, chlorine and sulfur in nature to form various compounds. Because cadmium was a mutagen and was highly toxic, it was also known as an itai-itai disease. This study investigated various physiological disorders caused by the absorption of cadmium by Pleurotus ostreatus when the cadmium was treated by concentration in the mycelium of Pleurotus ostreatus. The fresh weight, pH, and dry weight of mycelia treated with CdCl2 at 10 ppm and 100 ppm on PDB medium were measured. Fresh weight of Pleurotus ostreatus treated with 10 ppm in PDB medium was 0.05 g. The weight of the building was 0.0009g. The pH on the PDB medium was also found to be 4.84. The above results showed that CdCl2 affects mushroom growth, and we will confirm genes involved in CdCl2 uptake by confirming RNA express levels in the future study.
Acephate is an organophosphorus pesticide and is used as a pesticide. It is mainly used to control aphids and is also used to control thrips. When heated and decomposed, it has the property of releasing toxic smoke containing oxides such as phosphorus, nitrogen, and sulfur. As a result of checking PDA, PDB, and pH to confirm the change in the growth amount of top mycelium according to the amount of acephate added, there was no significant difference between treatment groups in PDA. In the PDB, untreated live weight was 0.62g, dry weight 0.02g, pH 5.3, acetate 10ppm live weight 0.66g, dry weight 0.02g, pH 5.3 100ppm live weight 2.91g, dry weight 0.11g pH 5.8.
The color of the Pleurotus ostreatus pileus is black, gray to yellow, and pink to yellow, etc. the transcriptomes of the white Pleurotus ostreatus "Baekseon" and the black Pleurotus ostreatus "Heuktari" with different shades were analyzed to confirm the difference between the color of the Pleurotus ostreatus and the amount of gene expression. The results are as follows. As a result of the analysis of oyster transcripts, 12,460 genes were expressed, and 1080 genes were identified with an expression level of 2-fold change or more. Among them, 536 genes were up-regulated and 544 were down-regulated. Among the up-regulated genes, carbohydrate esterase family 1 protein, glycosyltransferase family 58 protein, cora superfamily, and copper-amine-oxidase superfamily were identified. Among the down-regulated genes, polysaccharide lyase family 3 protein, cytochrome C1 protein, pleurotolysin B precursor Etc. were confirmed.
Several studies have demonstrated a protective effect of estrogen against the risk of developing neurodegenerative diseases; however, the molecular mechanisms involved have not been fully addressed. Isoflavones have been proposed as potential alternatives to estrogen replacement therapy. Therefore, in the present study, we investigated effects of isoflavones on cell death and tau phosphorylation in SH-SY5Y human neuroblastoma cells. Cells were treated with tunicamycin (TM) to induce endoplasmic reticulum (ER) stress-mediated toxicity, which is involved in development of neurodegenerative diseases. Treatment of cells with either 17β-estradiol or isoflavones (either genistein or daidzein) significantly protected cells against cell death. The protective effect against cell death was blocked by a specific estrogen receptor blocker, ICI 182,780, suggesting that isoflavones protect against cell death via estrogen receptor-dependent pathways. Isoflavones also suppressed ER stress as determined by decreased expressions of the immunoglobulin binding protein (BiP) mRNA, spliced X-box binding protein-1 (Xbp-1) mRNAs, and C/EBP homologous protein (CHOP). TM activated glycogen synthase kinase 3β (GSK3β), a kinase involved in tau phosphorylation; in contrast, isoflavones inactivated GSK3β and decreased tau hyperphosphorylation. In conclusion, our results clearly demonstrate that isoflavones prevent ER stress-mediated neurotoxicity by inhibiting tau hyperphosphorylation in SH-SY5Y cells.
Genetic responses of the edible seaweed Porphyra yezoensis tissue to acid shock have been compared using differential display technique. The tissue was challenged in seawater containing 0.05% hydrogen chloride (pH 3.0) for 5 min, then rehabilitated in normal seawater for 10 min, 30 min, 60 min and 4 hrs. Total RNA extracted by the LiCI-guanidium method was reverse transcribed and amplified by PCR with arbitrary primers. The amplified fragment responded by the acid shock was selectively isolated from agarose gel and sequenced with DNA auto sequencer. Sequence (1056 bp) of the cDNA contained at least two genes for ASP7K (MW 7418) and ASP5K (MW 5512) proteins.
