Figure Lengend Snippet: Elevated PSMD14 expression enhances the progression of lung adenocarcinoma. (A) RT-qPCR analysis revealed that the expression of PSMD14 was significantly elevated in LUAD tissues and cells compared to normal tissues and cells. (B) Western blot revealed an increase in the expression of PSMD14 protein in A549, H1299, and H358 compared to BEAS-2B. (C) Western blot revealed the expression of PSMD14 protein in LUAD tissues was significantly higher than that in paracancer tissues. (D) RT-qPCR indicated a knockdown efficiency greater than 50% in A549 and H1299 cells. (E) Western blot revealed the knockdown efficiency of PSMD14 in A549 and H1299 cells. (F) The CCK-8 assay showed the cell viability of both the PSMD14 knockdown and control groups, with results indicating a significant decrease in cell viability within the knockdown group. (G) Colony formation assay revealed a significant decrease in cell proliferation within the PSMD14 knockdown group according to crystal violet staining. (H,I) The cell scratch assay demonstrated a significant decrease in cell migration ability in the PSMD14 knockdown group compared to the control group in A549 (H) and H1299 (I) cells. Scale bar =200 µm. (J) Transwell invasion assay showed a significant decrease in cell invasion ability in the PSMD14 knockdown group compared to the control group according to crystal violet staining. Scale bar =200 µm. (K) Transwell migration assay showed a significant decrease in cell invasion ability in the PSMD14 knockdown group compared to the control group according to crystal violet staining.

Figure Lengend Snippet: AGR2 protein stability is regulated by PSMD14 via deubiquitination. (A) The HA- PSMD14 and Myc- AGR2 plasmids were cotransfected into HEK-293T cells, followed by the immunoprecipitation of cell lysates using either anti-HA or anti-Myc antibodies. (B) Immunoprecipitation of A549 and H1299 cell lysates was performed using anti- PSMD14 and anti- AGR2 antibodies, followed by analysis via immunoblotting, with the IgG antibody serving as a control. (C) Western blot showed a significant decrease in the level of AGR2 protein following PSMD14 knockdown. (D) Western blot showed the level of AGR2 protein increased following PSMD14 overexpression. (E) Western blot revealed that treatment with MG132 resulted in the reversal of AGR2 protein level decrease caused by PSMD14 knockdown. (F) The left panel shows the Western blot result of AGR2 protein levels in PSMD14 knockdown and control cells at 0, 3, 6, and 12 hours after CHX treatment. The right panel shows the corresponding AGR2 protein degradation rates between the two groups. (G) The left panel shows the Western blot result of AGR2 protein levels in PSMD14 overexpression and control cells at 0, 3, 6, and 12 hours after CHX treatment. The right panel shows the corresponding AGR2 protein degradation rates between the two groups. (H) Western blotting showed that PSMD14 knockdown increased the ubiquitin level of AGR2 protein compared to the control group. (I) Western blotting showed that PSMD14 overexpression decreased the ubiquitin level of AGR2 protein compared to the control group. ***, P<0.001.
