Objective:To explore the mechanism by which SRY-related high mobility group-box 9 (SOX9) promotes the epithelial mesenchymal transition (EMT) of non-small cell lung cancer (NSCLC) A549 cells via the Wnt/β-catenin pathway. Methods: The human NSCLCA549 cell line was divided into three groups: OE-NC group, OE-SOX9 group and OE-SOX9+XAV-939 group. The cells in OESOX9 group were transfected with SOX9 pcDNA plasmid to up-regulate the expression level of SOX9; The cells in OE-SOX9+XAV939 group were transfected with SOX9 pcDNA plasmid while the β-catenin inhibitor XAV-939 (1.0 μmol/L) was added to the medium. qPCR was used to detect SOX9 mRNA levels; CCK-8 was used to examine the proliferation of A549 cells; Wound-healing assay and Transwell chamber assay were used to detect the migration and invasion ofA549 cells, respectively; and WB was used to detect protein expressions of SOX9, β-catenin, E-cadherin, γ-catenin, N-cadherin and vimentin. Results: The mRNA and protein levels of SOX9 in OE-SOX9 group and OE-SOX9+XAV-939 group were significantly higher than those in the OE-NC group after transfection (all P< 0.05), while there was no significant difference between the OE-SOX9 group and the OE-SOX9+XAV-939 group (P>0.05). The proliferation, migration and invasion of cells in OE-SOX9 group were significantly higher than those in OE-NC group; however, those abilities in OE-SOX9+XAV-939 group were significantly lower than those in OE-SOX9 group (all P<0.05). The level of β-catenin protein in OE-SOX9 group was significantly higher than that in the OE-NC group, while the level of β-catenin protein in OE-SOX9+XAV-939 group was lower than that in OE-SOX9 group (all P<0.05). Compared with the OE-NC group, the levels of phenotypic markers of epithelial cells, E-cadherin and γ-catenin, were down-regulated, and the phenotypic markers of mesenchymal cells, N-cadherin and vimentin, were up-regulated in cells of OE-SOX9 group; however, E-cadherin and γ-catenin were higher, and N-cadherin and vimentin were lower in OE-SOX9+XAV-939 group than those in OE-SOX9 group (all P<0.05). Conclusion: SOX9 could promote proliferation, migration and EMT of NSCLCA549 cells by activating the Wnt/β-catenin pathway.

BACKGROUND:Abnormal extracellular matrix accumulation and excessive proliferation of fibroblasts are the main manifestations of pathological scars.Excessive proliferation of fibroblasts leads to the production of large amounts of collagen-based extracellular matrix.Therefore,to investigate the role of fibroblast fibrosis in the formation of pathological scar will provide a new idea for revealing the mechanism of pathological scar and biological therapy. OBJECTIVE:To investigate the effect of RAS-selective lethal small molecule 3(RSL3)on the fibrosis of human pathological scar fibroblasts. METHODS:Then cases of pathological scar tissue and normal skin tissue samples from the same individuals,provided by the Department of Burn Plastic Surgery,General Hospital of Ningxia Medical University,were collected.Fibroblasts of human pathological scar and human normal skin were extracted and used in the following experiments.The general condition of the pathological scar tissue and the normal skin tissue was detected by hematoxylin-eosin staining.The appearance of fibroblasts from pathological scar and normal skin were observed by inverted microscope.The fibroblasts were verified by immunofluorescence assay.The cells were treated with different concentrations of RSL3(1,3,5,7,9,11,13 μmol/L).The inhibitory concentration of RSL3 on fibroblasts was detected by cell counting kit-8.Control group(without treatment)and RSL3 intervention group(treated with 7 μmol/L RSL3 for 24 hours)were set up.The mRNA and protein expressions of glutathione peroxidase 4,type Ⅰ collagen,type Ⅲ collagen and α-smooth muscle actin were detected by Qrt-PCR and western blot,respectively.Level of malondialdehyde in cells was detected.The residual scratch area was measured by cell scratch test after 24 hours to calculate the percentage of residual scratch area. RESULTS AND CONCLUSION:The expression of glutathione peroxidase 4 in the pathological scar group was higher than that in the normal skin group(Mrna:t=3.252,P<0.01;protein:t=5.075,P<0.01).The expression of glutathione peroxidase 4 in the pathological scar fibroblast group was higher than that in the normal skin fibroblast group(Mrna:t=10.32,P<0.01;protein:t=26.22,P<0.01).Compared with the control group,the expression of glutathione peroxidase 4 was decreased(Mrna:t=2.798,P<0.05;protein:t=4.643,P<0.01),the content of malondialdehyde was increased(t=2.917,P<0.05),the expression of type Ⅰ collagen(Mrna:t=15.84,P<0.01;protein:t=4.610,P<0.01),type Ⅲ collagen(Mrna:t=28.86,P<0.01;protein:t=7.713,P<0.01)and α-smooth muscle actin(Mrna:t=2.671,P<0.05;protein:t=7.417,P<0.01)were decreased in the RSL3 intervention group.Compared with the control group,the migration ability was weakened in the RSL3 intervention group(t=14.06,P<0.01).To conclude,RSL3 can inhibit the expression of glutathione peroxidase 4 and then inhibit the ability of fibrosis and migration of pathological scar fibroblasts.

Objective:To investigate the efficacy and adverse effects of first-line immunotherapy combined with chemotherapy in elderly patients with small cell lung cancer(SCLC)in population of real world.Methods:A total of 148 elderly SCLC patients(age ≥65 years old)underwent pathological diagnosis were retrospectively analyzed from January 2013 to June 2023.103 patients received chemotherapy(chemotherapy group), and 45 patients received immunotherapy combined with chemotherapy(combination group). Patients were divided into senior group(≥75 years old)and younger group(<75 years old)by age.To compare the efficacy of different regimens in first-line treatment, the expression of programmed death-ligand 1(PD-L1)and tumor mutational burden(TMB)were evaluated.Response evaluation criteria in solid tumors(RECIST)version 1.1 was used to evaluate the efficacy, and common terminology criteria for adverse events(CTCAE)version 4.03 was used to evaluate immune-related adverse.Kaplan-meier and Log-rank test were performed.Cox regression was used in prognostic analysis.Results:The overall response rate(ORR)of the first-line combination group in elderly SCLC patients was 79.1%(34/43), which was higher than that of the chemotherapy group 63.2%(60/95), but the difference did not reach statistical significance( χ2=3.451, P=0.063). ORR was significantly higher in the combination group than in the chemotherapy group for patients in the ≥75-year-old group, 87.5%(7/8) vs.48.6%(17/35), respectively( χ2=4.001, P=0.045). The difference in median progression-free survival time(mPFS)in the combination group compared with the chemotherapy group was not statistically significant in the overall patients(5.43 months vs.6.07 months, P=0.660). The combination group prolonged patients' median overall survival time(mOS)compared with the chemotherapy group, but the difference did not reach statistical significance(13.63 months vs.11.97 months, P=0.205). In patients ≥75 years old, mPFS was lower in the combination group than in the chemotherapy group(2.97 months vs.6.47 months), but mOS was prolonged compared with that in the chemotherapy group(13.50 months vs.11.40 months), and none of the differences reached statistical significance(both P>0.05). The differences in mPFS and mOS between the combination group and the chemotherapy group were not statistically significant in patients <75 years old(both P>0.05). In elderly patients with severe comorbidities, mPFS and mOS were lower in the combination group than in the chemotherapy group(5.40 months vs.7.30 months and 10.70 months vs.12.27 months, both P>0.05). In patients without severe comorbidities, the difference in mPFS between the combination group and the chemotherapy group was not statistically significant( P>0.05), but the mOS was significantly longer in the combination group(20.57 months vs.11.57 months, P=0.054). Elderly SCLC patients had a positive PD-L1 tumor cell positive proportion score(TPS)rate(≥1%)of 23.5%(4/17)and a high TMB(≥9 mut/Mb)expression rate of 69.0%(11/16). The overall incidence of immune-related adverse reactions was 71.0%(32/45), grade 3 or higher 33.3%(15/45), and the most common grade 3 adverse reactions were rash, immune-related pneumonia and malaise. Conclusions:First-line immune-combination chemotherapy improves ORR and mOS over chemotherapy in elderly SCLC patients; mOS benefit of immune-combination chemotherapy is more pronounced in patients ≥75 years of age without severe comorbidities, low PD-L1 positivity and high TMB expression are present in elderly SCLC patients, and immune-related adverse effects are generally manageable in elderly patients.
