Of these, rno-miR-298 was confirmed to be increased at 1 week postinjection by reverse transcription-PCR (RT-PCR).\nDISCUSSION AND CONCLUSION: Blood miRNAs could be useful as biomarkers for exposure to nanoparticles. miR-298 regulates β-amyloid (Aβ) precursor protein-converting enzyme-1 (BACE1) in Alzheimer's disease.","tracks":[{"project":"Allie","denotations":[{"id":"SS1_23030236_4_0","span":{"begin":318,"end":353},"obj":"expanded"},{"id":"SS2_23030236_4_0","span":{"begin":355,"end":359},"obj":"abbr"},{"id":"SS1_23030236_9_0","span":{"begin":630,"end":655},"obj":"expanded"},{"id":"SS2_23030236_9_0","span":{"begin":657,"end":663},"obj":"abbr"}],"relations":[{"id":"AE1_23030236_4_0","pred":"abbreviatedTo","subj":"SS1_23030236_4_0","obj":"SS2_23030236_4_0"},{"id":"AE1_23030236_9_0","pred":"abbreviatedTo","subj":"SS1_23030236_9_0","obj":"SS2_23030236_9_0"}],"attributes":[{"subj":"SS1_23030236_4_0","pred":"source","obj":"Allie"},{"subj":"SS2_23030236_4_0","pred":"source","obj":"Allie"},{"subj":"SS1_23030236_9_0","pred":"source","obj":"Allie"},{"subj":"SS2_23030236_9_0","pred":"source","obj":"Allie"}]}],"config":{"attribute types":[{"pred":"source","value type":"selection","values":[{"id":"Allie","color":"#ec93e0","default":true}]}]}}
