    (A) Schematic overview of the DDCreER system. In the absence of both 4-hydroxytamoxifen (4-OHT) and trimethoprim (TMP), the destabilizing domain (DD) fused <t>CreER</t> is targeted for proteasomal degradation. Addition of TMP alone stabilizes the DD-fused CreER, resembling the conventional CreER system and potentially allowing background recombination. Addition of 4-OHT alone promotes nuclear translocation of DDCreER, but only of the residual protein that has not yet been degraded, permitting low-level recombination. Only in the presence of both 4-OHT and TMP is DDCreER stabilized and translocated to the nucleus, enabling efficient recombination. Created in BioRender. Gurzov, E. (2025) https://BioRender.com/uteh37g (B) Confocal images of livers from 10 days post-fertilization (dpf) Tg(fabp10a:BB-NTR); Tg(fabp10a:DDCreER) zebrafish larvae following treatment with 172 µM TMP, 10 µM 4-OHT, or both together. DMSO (1%) served as a negative control. Fluorescent markers indicate non-recombined cells (mTagBFP2+), and recombined hepatocytes (H2B-mGL+ or mCherry-NTR+). Scale bar: 50 µm. (C) Quantification of recombination efficiency in Tg(fabp10a:BB-NTR); Tg(fabp10a:DDCreER) larvae under different treatments. Bar plots show the percentage of hepatocytes expressing each fluorescent marker (mTagBFP2, H2B-mGL, or mCherry). Data represents Mean ± SD. Statistical significance was calculated using two-way ANOVA followed by Tukey’s multiple comparisons test. (D) Comparison of recombination efficiency between the DDCreER and ERCreER systems, based on the percentage of BFP+ hepatocytes. Bar plots depict Mean ± SD. Statistical significance was assessed using ordinary one-way ANOVA followed by Tukey’s multiple comparisons test. Significantly lower proportions of unrecombined (BFP+) cells were observed in DDCreER-expressing livers.

Fluorescent markers indicate non-recombined nls-mTagBFP2+, or recombined H2B-mGL+ or mCherry-NTR+ hepatocytes. Scale bar: 20 µm. (B) Bar plot representing Mean ± SD showing quantification of background recombination at 2 mpf based on histological analysis of liver sections from Tg(fabp10a:NTR) zebrafish. Significance determined by two-way ANOVA followed by Tukey’s multiple comparisons test. (C) Flow cytometry-based quantification of background recombination at 3 mpf in Tg(fabp10a:BB-NTR) zebrafish. The proportion of mTagBFP2+, H2B-mGL+, mCherry+, and double-positive (H2B-mGL+/mCherry+) hepatocytes was measured by FACS. Each dot represents one animal and the bar plots represent Mean ± SD. Statistical analysis performed using two-way ANOVA followed by Tukey’s multiple comparisons test.

    (A) Schematic overview of the DDCreER system. In the absence of both 4-hydroxytamoxifen (4-OHT) and trimethoprim (TMP), the destabilizing domain (DD) fused CreER is targeted for proteasomal degradation. Addition of TMP alone stabilizes the DD-fused CreER, resembling the conventional CreER system and potentially allowing background recombination. Addition of 4-OHT alone promotes nuclear translocation of DDCreER, but only of the residual protein that has not yet been degraded, permitting low-level recombination. Only in the presence of both 4-OHT and TMP is DDCreER stabilized and translocated to the nucleus, enabling efficient recombination. Created in BioRender. Gurzov, E. (2025) https://BioRender.com/uteh37g (B) Confocal images of livers from 10 days post-fertilization (dpf) Tg(fabp10a:BB-NTR); Tg(fabp10a:DDCreER) zebrafish larvae following treatment with 172 µM TMP, 10 µM 4-OHT, or both together. DMSO (1%) served as a negative control. Fluorescent markers indicate non-recombined cells (mTagBFP2+), and recombined hepatocytes (H2B-mGL+ or mCherry-NTR+). Scale bar: 50 µm. (C) Quantification of recombination efficiency in Tg(fabp10a:BB-NTR); Tg(fabp10a:DDCreER) larvae under different treatments. Bar plots show the percentage of hepatocytes expressing each fluorescent marker (mTagBFP2, H2B-mGL, or mCherry). Data represents Mean ± SD. Statistical significance was calculated using two-way ANOVA followed by Tukey’s multiple comparisons test. (D) Comparison of recombination efficiency between the DDCreER and ERCreER systems, based on the percentage of BFP+ hepatocytes. Bar plots depict Mean ± SD. Statistical significance was assessed using ordinary one-way ANOVA followed by Tukey’s multiple comparisons test. Significantly lower proportions of unrecombined (BFP+) cells were observed in DDCreER-expressing livers.
