体外研究 (In Vitro) | Isotretinoin (13-cis-Retinoic acid) may act as a pro-drug that is converted intracellularly to metabolites that are agonists for RAR and RXR nuclear receptors[1]. Isotretinoin is highly sensitive to air, heat, and light[3]. Isotretinoin (0-40 μM; 24-96 h) significantly inhibits HepG2 cell viability[4]. Isotretinoin (10 μM; 48 h) down-regulatesc-MYCmRNA expression and this is partially due to P1 or P2 promoter activity[4].
Cell Viability Assay[4] Cell Line: | HepG2 | Concentration: | 0.1, 0.5, 1, 5, 10, 20, and 40 μM | Incubation Time: | 24, 48, 72, and 96 h | Result: | Showed a significant reduction in cell viability (less than 30%) at 96 h for all doses. |
RT-PCR[4] Cell Line: | HepG2 | Concentration: | 10 μM | Incubation Time: | 48 h | Result: | Significantly reduced the expression ofc-MYCmRNA by ~80%. |

体内研究 (In Vivo) | Isotretinoin (13-cis-Retinoic acid) (1.3-481 μg/L; inhalation exposure; 45 min daily for 2 weeks) is an effective lung cancer chemopreventive agent in A/J Mice[2]. Isotretinoin accelerates alveolar repair after exodontia in rats[3].
Animal Model: | Male A/J mice, lung carcinogenesis model[2] | Dosage: | 1.3, 20.7, or 481 μg/L | Administration: | Inhalation exposure, 45 min daily for 2 weeks | Result: | Reduced the tumor multiplicity. Caused up-regulation of lung tissue nuclear retinoic acid receptors (RARs) relative to vehicle-exposed mice, RARα (3.9-fold vehicle), RARβ (3.3-fold), and RARγ (3.7-fold) at 20.7 μg/L. |
Animal Model: | Wistar rats, tooth extraction model[3] | Dosage: | 7.5 mg/kg | Administration: | Oral gavage, daily for 30 days | Result: | Accelerated the process of alveolar repair, significantly decreased serum calcium levels. |
