| Treatment protocol |
Mice were gavaged once with sesame oil vehicle or 30 ug/kg TCDD and livers collected at 2, 4, 8, 12, 24, or 72 hours following gavage.

| Extraction protocol |
Nuclei were isolated from frozen liver samples (~200mg) as previously described (dx.doi.org/10.17504/protocols.io.3fkgjkw). Briefly, livers were diced in EZ Lysis Buffer (Sigma-Aldrich), homogenized using a disposable dounce homogenizer, and incubated on ice for 5 minutes. The homogenate was filtered using a 70 μm cell strainer, transferred to microcentrifuge tube, and centrifuged at 500 x g and 4°C for 5 minutes. The supernatant was removed and fresh EZ lysis buffer was added for an additional 5 minutes on ice following by centrifugation at 500 x g and 4°C for 5 minutes. The nuclei pellet was washed twice in nuclei wash and resuspend buffer (1X PBS, 1% BSA, 0.2 U/μL RNAse inhibitor) with 5 minute incubations on ice. Following the washes, the nuclei pellet was resuspended in nuclei wash and resuspend buffer containing DAPI (10 μg/mL). The resuspended nuclei were filtered with 40 μm strainer and immediately underwent fluorescence activated cell sorting (FACS) using a BD FACSAria IIu (BD Biosciences, San Jose, CA) with 70 μm nozzle.

| Data processing |
CellRanger 4.0.0 was used to align reads to a custom reference genome which included introns and exons to consider pre-mRNA and mature mRNA present in the nuclei.
Raw counts were further analysed using Scanpy v1.9.3. Each sample was filtered for (i) genes expressed in at least 3 nuclei, (ii) nuclei which express at least 100 genes, and (iii) ≤1% mitochondrial genes
Scrublet v0.2.3 was used to remove putative doublets.
All libraries were integrated using using scVI v0.20.3, while accounting for dose and time as categorical covariates and using a latent variable of 40.
