Generation of Ragulator-deficient clone with total mTORC1 activity. A , schematic representation of the findings of this study, depicting the phosphorylation of the TFEB substrate by mTORC1 bound to the Ragulator-Rag scaffold. B , the results of Western blotting studies on ΔRagulator and parental RAW264.7 cells. Lamtor1, Lamtor2, Lamtor3, Lamtor4, and <t>Lamtor5</t> are components of the Ragulator complex; β-actin served as the internal control; mTOR and Raptor are components of mTORC1; RagC is necessary for the docking of TFEB to Ragulator. C , representative result of Western blotting studies for determining the activity of mTORC1. The control RAW264.7 cells and ΔRagulator cells were cultured in nutrient-sufficient and serum-supplemented DMEM. The phosphorylation of S6K in these cells was abolished following treatment with the mTOR kinase inhibitor, Torin1, at the indicated concentrations for 1 h. D , the densities of the p-S6K and S6K bands in panel C were quantified. The ratio of densities of the p-S6K band to S6K band is shown. Four independent experiments were performed. Bars indicate the median. Statistical significance was calculated using Mann–Whitney U test. E , the results of Upstream Regulator Analysis, as determined using the web-based software, Ingenuity Pathway Analysis. The pathways with z scores less than −2 are significantly inactivated in the ΔRagulator cells, compared to the RAW264.7 cells. The z score for the TFEB pathway was >2, which indicates that TFEB is significantly activated in the ΔRagulator cells than in the control RAW264.7 cells. F , the sizes of the ΔRagulator cells were larger than those of the parental RAW264.7 cells. The cell sizes of 1 × 10 4 cells were estimated using flow cytometry. Statistical significance was calculated using Welch’s t test. G , Western blotting for determining the phosphorylation of TSC2. Control RAW264.7 cells and ΔRagulator cells were cultured in nutrient-sufficient and serum-supplemented DMEM. Three biological triplicates were examined. H , the densities of the p-TSC2 and the TSC2 bands in panel G were quantified. The ratio of densities of the p-TSC2 band to TSC2 band is shown. Statistical significance was calculated using the Mann–Whitney U test. mTORC1, mammalian target of rapamycin complex 1; TFEB transcription factor EB.

Control RAW264.7 cells and ΔRagulator cells were cultured in nutrient-sufficient and serum-supplemented DMEM. Three biological triplicates were examined. H , the densities of the p-TSC2 and the TSC2 bands in panel G were quantified. The ratio of densities of the p-TSC2 band to TSC2 band is shown. Statistical significance was calculated using the Mann–Whitney U test. mTORC1, mammalian target of rapamycin complex 1; TFEB transcription factor EB.

Figure Lengend Snippet: Generation of Ragulator-deficient clone with total mTORC1 activity. A , schematic representation of the findings of this study, depicting the phosphorylation of the TFEB substrate by mTORC1 bound to the Ragulator-Rag scaffold. B , the results of Western blotting studies on ΔRagulator and parental RAW264.7 cells. Lamtor1, Lamtor2, Lamtor3, Lamtor4, and Lamtor5 are components of the Ragulator complex; β-actin served as the internal control; mTOR and Raptor are components of mTORC1; RagC is necessary for the docking of TFEB to Ragulator. C , representative result of Western blotting studies for determining the activity of mTORC1. The control RAW264.7 cells and ΔRagulator cells were cultured in nutrient-sufficient and serum-supplemented DMEM. The phosphorylation of S6K in these cells was abolished following treatment with the mTOR kinase inhibitor, Torin1, at the indicated concentrations for 1 h. D , the densities of the p-S6K and S6K bands in panel C were quantified. The ratio of densities of the p-S6K band to S6K band is shown. Four independent experiments were performed. Bars indicate the median. Statistical significance was calculated using Mann–Whitney U test. E , the results of Upstream Regulator Analysis, as determined using the web-based software, Ingenuity Pathway Analysis. The pathways with z scores less than −2 are significantly inactivated in the ΔRagulator cells, compared to the RAW264.7 cells. The z score for the TFEB pathway was >2, which indicates that TFEB is significantly activated in the ΔRagulator cells than in the control RAW264.7 cells. F , the sizes of the ΔRagulator cells were larger than those of the parental RAW264.7 cells. The cell sizes of 1 × 10 4 cells were estimated using flow cytometry. Statistical significance was calculated using Welch’s t test. G , Western blotting for determining the phosphorylation of TSC2. Control RAW264.7 cells and ΔRagulator cells were cultured in nutrient-sufficient and serum-supplemented DMEM. Three biological triplicates were examined. H , the densities of the p-TSC2 and the TSC2 bands in panel G were quantified. The ratio of densities of the p-TSC2 band to TSC2 band is shown. Statistical significance was calculated using the Mann–Whitney U test. mTORC1, mammalian target of rapamycin complex 1; TFEB transcription factor EB.
