Figure Lengend Snippet: FOXL2 SUMOylation intricately regulates increased expression in CAFs. ( A ) SUMOylation sites of FOXL2 was analyzed by SUMOplot™ analysis. Shown are the top 7 predicted lysine residues; ( B ) In vitro sumoylation assay was employed to confirm the predicted SUMOylation sites using HA-tagged wild-type (WT), or the K25R, K87R, K114R, K150R, and 4KR (where K25, K87, K114 and K150 were all mutated to R). Shown is a representative blot and densitometry analysis of SUMOylated-FOXL2/Total FOXL2; ( C ) The association between SUMOylation and FOXL2 stability was determined by western blotting in HEK-293T cells using α-HA. Cells were transfected with either HA-FOXL2-WT or HA-FOXL2-K25/87R (double mutant, 2KR). The membrane was stripped and re-probed with GAPDH to confirm equivalent loading. Shown is a representative blot and densitometry analysis of three technical replicates; ( D ) Cells were transfected with HA-FOXL2-WT or, HA-FOXL2-2KR ± His-SUMO1. CHX (100 µg/ml) was added to inhibit translation allowing tracking of FOXL2 stability in the presence and absence of His-SUMO1. Blots were probed with α-HA and re-probed with GAPDH to confirm equivalent loading. Shown is a representative blot and densitometry analysis of three technical replicates; ( E ) DMSO (control), MG132 (proteasome inhibitor) or chloroquine (lysosome inhibitor) were added into HEK-293T cells transfected with HA-FOXL2-WT or HA-FOXL2-2KR, before CHX (100 µg/ml) was added. Blots were probed with α-HA and re-probed with GAPDH to confirm equivalent loading. Shown is a representative blot; ( F ) IP assay was used to test the association between FOXL2 SUMOylation and ubiquitination. Lysates obtained from HEK-293T cells transfected with HA-FOXL2-WT or HA-FOXL2-2KR, along with FLAG-UBC9, were immunoprecipitated using α-HA antibody and then probed with α-FLAG antibody.

Figure Lengend Snippet: FOXL2 SUMOylation requires SUMO1 and UBC9/UBE2I. ( A ) Putative interaction of FOXL2 with SUMO1, SUMO2, SUMO3, and SUMO4 was detected by String analysis ( https://cn.string-db.org/ ); ( B ) In vitro sumoylation assay was employed to confirm String analysis’s prediction of SUMO1, HEK-293T cells were transfected with HA-FOXL2-WT, FLAG-UBC9, and His-SUMO1-4. In vitro SUMOylation assay using Ni 2+ -NTA pull-down determined that FOXL2 was mainly modified by SUMO1. Shown is a representative blot; ( C ) In vitro sumoylation assay was employed to determine whether UBC9 is compulsorily required for FOXL2 SUMOylation. HEK-293T cells were transfected with HA-FOXL2-WT and His-SUMO1 ± FLAG-UBC9. In vitro SUMOylation using Ni 2+ -NTA pull-down assay determined that UBC9 is required for FOXL2 SUMOylation. Shown is a representative blot; ( D ) In vitro sumoylation assay was employed to determine whether UBC9 is compulsorily required for FOXL2 SUMOylation in CAFs. CAFs were transduced using either a non-targeting control shRNA or shRNA targeting UBC9 . Transduced cells were transfected with HA-FOXL2-WT and His-SUMO1. In vitro SUMOylation using Ni 2+ -NTA pull-down assay determined that UBC9 is required for FOXL2 SUMOylation. Shown is a representative blot

Article Title: Ube2i deletion in adipocytes causes lipoatrophy in mice

doi: 10.1016/j.molmet.2021.101221

Figure Lengend Snippet: Generation of conditional Ube2i gene deletion mice. (A) Ube2i fl/fl mice were generated using CRISPR/Cas9 gene editing. Exons 3 and 4 of the Ube2i ( Ubc9 ) gene were targeted by sgRNAs designed complementary to intronic sequences flanking the exons, then loxP sequences were introduced by DNA donor oligonucleotides. LoxP sites were inserted before exon 3 and after exon 4 (black arrows). Primers detect the 5’ (P1, P2) and 3’ (P3, P4) loxP sequences. (B) PCR analyses of floxed alleles at the targeted loci in genomic DNA extracted from ear clips of wild-type (+/+), fl/+, and fl/fl mice. PCR products were run on agarose gels with expected band sizes for P1–P2: wild-type (+) 319 bp and loxP allele (fl) 353 bp and P3–P4: wild-type (+) 427 bp and loxP allele (fl) 461 bp. The image shows a wild-type control #1107 +/+, founder heterozygous mouse #974 fl/+, and homozygous F2 offspring #1091 fl/fl. (C) Western blot analysis of UBE2I expression in inguinal WAT (iWAT) derived fibroblasts from Ube2i fl/fl mice after transduction with adenoviral GFP or Cre. To determine cell autonomous effects of Ube2i deletion in adipocytes, tamoxifen inducible Cre-expressing mice ( CAG-Cre ) were crossed with Ube2i fl/fl mice. iWAT SVF cells were isolated from CAG-Cre;Ube2i fl/fl and Ube2i fl/fl control mice. All cells were treated with tamoxifen to induce Cre recombination followed by adipocyte differentiation (diff) for eight days. (D) Western blot analysis and (E) relative gene expression by qPCR were performed to assess Ube2i depletion, adipocyte maturation, and beige fat cell markers. Gray = Ube2i fl/fl , yellow = CAG-Cre;Ube2i fl/fl . Data are presented as mean +/− SEM, ∗p < 0.05. (F) Brightfield and fluorescent images of differentiated Ube2i fl/fl and CAG-Cre;Ube2i fl/fl cells stained for lipids (green, LipidTOX), perilipin (red), and nuclei (blue, DAPI). Scale bars 50 μm. (G) Whole cell lysates from differentiated cells were subjected to Western blot analysis of cleaved (p41/43, p18) and uncleaved Caspase-8. (H) Strategy for generating adipocyte-specific Ube2i gene deletion. Ube2i fl/fl mice were bred with Adipoq-Cre mice to generate adipocyte-specific Ube2i knockout ( Ube2i a-KO ) and Ube2i fl/fl (control) mice. (I) To validate gene deletion of Ube2i , genomic DNA was extracted from Ube2i a-KO and Ube2i fl/fl gonadal WAT (gWAT) samples and PCR products were run on an agarose gel to detect the 5’ (P1, P2 primers) and 3’ (P3, P4 primers) loxP sequences, as well as a product that spans exons 3–4 (P1+P2+P4; 1597 bp, green arrow) or the deletion product (509 bp, red arrow). (J) Western blots of whole tissue lysates from iWAT and BAT of seven-day-old mice were probed for UBE2I and adiponectin (ADIPOQ), and HSP90 served as the invariant loading control.
