Gene expression profiles in rat lung following intratracheal instillation with impurity-free single-wall carbon nanotubes

Project description:To further development of our gene expression approach to assess the effects of manufactured nanomaterials at the transcriptional level, we have employed whole genome microarray expression profiling as a discovery platform to identify genes with the potential to distinguish characterization of physicochemical properties of impurity-free single-wall carbon nanotubes (SWCNTs). We have prepared two types of dispersed the SWCNTs, namely relatively small bundles and a short linear shape (CNT-1) and large bundles and a long linear shape (CNT-2), and attempted to characterize time-dependent changes in the gene expression of lung tissues until 90 days after intratracheal instillation with SWCNTs suspensions at 0.4 mg injected dose per rat. Groups of nine-week-old male Wistar rats (n= 4 per group/ time point) were intratracheally instilled with single-wall carbon nanotubes (SWCNTs) suspended in 0.4 ml of 1.0mg/mL bovine serum albumin (BSA) as a single injection 0.4 mg SWCNTs/ rat. Control groups received 1.0mg/mL BSA (vehicle control). After intratracheal instillation treatment, rats were housed within polycarbonate cages at a controlled temperature of 22 M-BM-0C with a chow diet ad libitum, and dissected at 1day, 3 days, 7 days, 30 days, and 90 days post-instillation. Right lungs of anesthetized rats were perfused with physiological saline, excised, and used for DNA microarray analysis.

Gene expression profiles in rat lung following intratracheal instillation with C60 fullerene particles

Project description:Gene expression profiling of the rat lung following intratracheal instillation with C60 fullerene particles was employed to gain insights into these molecular events. Groups of nine-week-old male Wistar rats (n= 4-6 per group/ time point) were intratracheally instilled with C60 fullerene suspended in 0.4 ml distilled water including 0.8% Tween-80 as a single injection (0.1 mg, 0.2 mg (LD: low doses) and 1.0 mg (HD: high dose) C60 fullerene/ rat). Control groups received 0.8 % Tween-80 (vehicle control). After intratracheal instillation treatment, rats were housed within polycarbonate cages at a controlled temperature of 22 °C with a chow diet ad libitum, and dissected at 3 days, 1 week, 1 month, 3 month, and 6 month post-instillation. Right lungs of anesthetized rats were perfused with physiological saline, excised, and used for DNA microarray analysis.

Gene expression profiles in rat lung following intratracheal instillation with single-wall carbon nanotubes (SWCNTs)

Project description:Gene expression profiling of the rat lung following intratracheal instillation with SWCNTs was employed to gain insights into these molecular events. We attempted to characterize time-dependent changes in the gene expression until 754 days after intratracheal instillation with SWCNTs suspensions at 0.2 mg (L-SWCNT) and 0.4 mg (H-SWCNT) injected dose per rat, and to identify the shift from the acute-phase to the chronic-phase phase on the basis of evaluation at the molecular level. Groups of nine-week-old male Wistar rats (n= 6 per group/ time point) were intratracheally instilled with single-wall carbon nanotubes (SWCNTs) suspended in 0.4 ml distilled water including 0.1% Triton X-100 as a single injection 0.1 mg (L-SWCNT) and 0.4 mg (H-SWCNT) SWCNTs/ rat). Control groups received 0.1% Triton X-100 (vehicle control). After intratracheal instillation treatment, rats were housed within polycarbonate cages at a controlled temperature of 22 M-BM-0C with a chow diet ad libitum, and dissected at 3 days, 7 days, 30 days, 90 days, 180 days, 365 days and 754 days post-instillation. Right lungs of anesthetized rats were perfused with physiological saline, excised, and used for DNA microarray analysis.

Long-term retention of pristine multi-walled carbon nanotubes in rat lungs after intratracheal instillation.

Project description:As a result of the growing potential industrial and medical applications of multi-walled carbon nanotubes (MWCNTs), people working in or residing near facilities that manufacture them may be exposed to airborne MWCNTs in the future. Because of concerns regarding their toxicity, quantitative data on the long-term clearance of pristine MWCNTs from the lungs are required. We administered pristine MWCNTs well dispersed in 0.5 mg ml(-1) Triton-X solution to rats at doses of 0.20 or 0.55 mg via intratracheal instillation and investigated clearance over a 12-month observation period. The pristine MWCNTs pulmonary burden was determined 1, 3, 7, 28, 91, 175 and 364 days after instillation using a method involving combustive oxidation and infrared analysis, combined with acid digestion and heat pretreatment. As 0.15- and 0.38-mg MWCNTs were detected 1 day after administration of 0.20 and 0.55 mg MWCNTs, respectively, approximately 30% of administrated MWCNTs may have been cleared by bronchial ciliary motion within 24 h of administration. After that, the pulmonary MWCNT burden did not decrease significantly over time for up to 364 days after instillation, suggesting that MWCNTs were not readily cleared from the lung. Transmission electron microscopy (TEM) showed that alveolar macrophages internalized the MWCNTs and retained in the lung for at least 364 days after instillation. MWCNTs were not detected in the liver or brain within the 364-day study period (<0.04 mg per liver, < 0.006 mg per brain).
