    The HEK293 cell line was targeted for CK1δ-/- knockout by the CRISPR-Cas9 system, using 2 different single guide RNA (sgRNA) sequences. Knockout clones were selected from single cells by GFP sorting followed by serial dilution, and gene editing was confirmed by sequencing. KO1 and KO2 had mono-allelic knockout of CK1δ, and KO3 and KO4 has bi-allelic knockout of CK1δ (Figure S1A). (A-B) Four clones of CK1δ knockout, KO1-4, were compared with the vector Cas9 in HEK293 for the levels of CK1δ, <t>CK1ε,</t> <t>4E-BP1,</t> p70S6K, RPS6, and actin by immunoblotting. (C) The same CK1δ knockout clones of HEK293 and Cas9 HEK293 cells were processed for the cap binding assay using m 7 GTP agarose beads to pull down cap binding proteins, which were then analyzed by immunoblotting. The ratio of eIF4G in the pulldown relative to the input cell lysate is an index of eIF4F assembly. (D) Polysome profiling was performed the in HEK293 cells with CK1δ knockout clones KO3 and KO4, in comparison to the control HEK293 cells with non-targeting Cas9. X-axis showed the sedimentations or fractions collected from 10–50% sucrose density gradient centrifugation. Y-axis showed the OD260 UV recording of RNA abundance. Data shown were the average of three experiments. RNP, ribonuclear protein; 40S, 40S small ribosome subunit; 60S, 60S large ribosome subunit; 80S, 80S monosome. (E) The same CK1δ knockout clones of HEK293 and Cas9 HEK293 cells were grown in 1μg/ml puromycin for 30 minutes.

    The HEK293 cell line was targeted for CK1δ-/- knockout by the CRISPR-Cas9 system, using 2 different single guide RNA (sgRNA) sequences. Knockout clones were selected from single cells by GFP sorting followed by serial dilution, and gene editing was confirmed by sequencing. KO1 and KO2 had mono-allelic knockout of CK1δ, and KO3 and KO4 has bi-allelic knockout of CK1δ (Figure S1A). (A-B) Four clones of CK1δ knockout, KO1-4, were compared with the vector Cas9 in HEK293 for the levels of CK1δ, <t>CK1ε,</t> <t>4E-BP1,</t> p70S6K, RPS6, and actin by immunoblotting. (C) The same CK1δ knockout clones of HEK293 and Cas9 HEK293 cells were processed for the cap binding assay using m 7 GTP agarose beads to pull down cap binding proteins, which were then analyzed by immunoblotting. The ratio of eIF4G in the pulldown relative to the input cell lysate is an index of eIF4F assembly. (D) Polysome profiling was performed the in HEK293 cells with CK1δ knockout clones KO3 and KO4, in comparison to the control HEK293 cells with non-targeting Cas9. X-axis showed the sedimentations or fractions collected from 10–50% sucrose density gradient centrifugation. Y-axis showed the OD260 UV recording of RNA abundance. Data shown were the average of three experiments. RNP, ribonuclear protein; 40S, 40S small ribosome subunit; 60S, 60S large ribosome subunit; 80S, 80S monosome. (E) The same CK1δ knockout clones of HEK293 and Cas9 HEK293 cells were grown in 1μg/ml puromycin for 30 minutes. Cell lysates were subjected to Western blotting using the anti-puromycin antibody in the SUnSET assay.

    The HEK293 cell line was targeted for CK1δ-/- knockout by the CRISPR-Cas9 system, using 2 different single guide RNA (sgRNA) sequences. Knockout clones were selected from single cells by GFP sorting followed by serial dilution, and gene editing was confirmed by sequencing. KO1 and KO2 had mono-allelic knockout of CK1δ, and KO3 and KO4 has bi-allelic knockout of CK1δ (Figure S1A). (A-B) Four clones of CK1δ knockout, KO1-4, were compared with the vector Cas9 in HEK293 for the levels of CK1δ, CK1ε, 4E-BP1, p70S6K, RPS6, and actin by immunoblotting. (C) The same CK1δ knockout clones of HEK293 and Cas9 HEK293 cells were processed for the cap binding assay using m 7 GTP agarose beads to pull down cap binding proteins, which were then analyzed by immunoblotting. The ratio of eIF4G in the pulldown relative to the input cell lysate is an index of eIF4F assembly. (D) Polysome profiling was performed the in HEK293 cells with CK1δ knockout clones KO3 and KO4, in comparison to the control HEK293 cells with non-targeting Cas9. X-axis showed the sedimentations or fractions collected from 10–50% sucrose density gradient centrifugation. Y-axis showed the OD260 UV recording of RNA abundance. Data shown were the average of three experiments. RNP, ribonuclear protein; 40S, 40S small ribosome subunit; 60S, 60S large ribosome subunit; 80S, 80S monosome. (E) The same CK1δ knockout clones of HEK293 and Cas9 HEK293 cells were grown in 1μg/ml puromycin for 30 minutes. Cell lysates were subjected to Western blotting using the anti-puromycin antibody in the SUnSET assay.

    MSJZT treatment inhibited the mTORC1 pathway, but not the mTORC2 pathway in lung homogenates. Western blot analysis was performed to investigate mTORC1 and mTORC2 activities and involved investigating the phosphorylation of their substrates, S6RP, p70S6K, 4E-BP1, Akt, and mTOR 2481, respectively. The expression of these proteins was quantified and represented as band intensity of phosphorylated proteins normalized to the relevant total proteins. The amount of loaded material was 100 μg. Data are expressed as means ± SEM ( n = 6 in each group). ∗ P < 0.05 and ∗∗ P < 0.01 versus the OVA group.
