Article Title: HACE1 prevents lung carcinogenesis via inhibition of RAC-family GTPases
doi: 10.1158/0008-5472.CAN-19-2270
Figure Lengend Snippet: HACE1 ubiquitylates GTP-RAC1 when bound to the NADPH oxidase complex, leading to RAC1 degradation and thereby controlling ROS production (top, left). HACE1 deficiency results in an accumulation of GTP-bound RAC1, increased NADPH oxidase activity and enhanced levels of genotoxic cellular ROS, promoting cancer progression (top, right). Additionally, deregulated RAC1 could promote tumor development by ROS-independent mechanisms. In the absence of the more abundant RAC1, the activity of GTP-RAC2 when bound to the NADPH oxidase complex is controlled by HACE1, leading to decreased cellular ROS levels (bottom, left). When HACE1 and RAC1 are both ablated, active GTP-RAC2 can compensate and promote cancer progression (bottom, right).

WT BMDMs cultured in MCSF for 7 days were serum starved for 4 hrs, trypsinized and were allowed to engage with α 4 β 1 ligand (H296) or α 2 β 1 ligand (collagen), followed by MCSF stimulation (50 ng/ml) for 15 min and Rac2 GTP pull down assay as described before. (B & C) Tumor volume (B) and mass (C) of LLC tumors grown in Rac2-/- mice treated with or without 1 million WT BMDMs or Rac2-/- BMDMs or WT GBMDMs. After 5 days of LLC tumor inoculation, Rac2-/- mice were treated either with 1 million WT BMDMs or GBMDMs or Rac2-/- BMDMs or every third day, until tumors were removed on day 21. Values are mean ± SEM ( n = 6-8). Statistical significance is assessed by two sample t -test where *denotes P <0.05, ** denotes P <0.01 and *** denotes P <0.001. Experiment was repeated three times with similar results. (D) Reversal of B16 metastasis by injection of WT BMDMs and not by WT GBMDMs in Rac2-/- mice. Figure shows representative photograph of pulmonary metastatic foci produced 15 days after intravenous injection of B16F10 cells in Rac2-/- mice and treated with 1 million WT BMDMs or WT GBMDMs. One dose of 1 million BMDMs or GBMDMs were given to Rac2-/- mice two days before inoculating 5×10 5 B16F10 cells intravenously followed by treatment with 1 million BMDM or GBMDM every third day, lungs were harvested on day 15. Data are representative of three independent experiments with 6–8 mice in each group. (E) Reversal of metastatic defect in Rac2-/- mice by local injections of 1 million WT BMDMs in the right lobe of lungs and 1 million WT GBMDMs or Rac2-/- BMDMs in the left lobe of Rac2-/- mice, followed by tail vein injections of B16 luciferase cells (5×10 5 ) after 2 days. The luciferase signal was monitored every third day on IVIS by injecting luciferin, until lungs were harvested on day 15 (n = 5). Data are representative of two independent experiments with 5–6 mice in each group.

Figure Lengend Snippet: (A) Graphic representation of novel integrin-Rac2 signaling axis in macrophages required for tumor growth, invasion, metastasis and the polarization of macrophages into M2 phenotype. (B) Interactome map developed from multiple-omic data which predicts how Rac2 regulates macrophage M2 differentiation. Nodes indicate genes either preselected for hierarchical analysis (colored borderer) or prioritized directly by the network propagation algorithm. Edges indicate protein-protein interactions. Node color indicates the protein or gene expression change in the Rac2-/- vs. WT condition.
