Objective The aim of this study was to investigate the effects of LncRNA OTUD6B-AS1 on the proliferation,migration and invasion of lung adenocarcinoma A549 cells. Methods Lung adenocarcinoma A549 cell line was cultured in vitro,and transient transfection of OTUD6B-AS1 and empty plasmid group were used as the control group.Overexpression and control cell models were constructed,and divided into OTUD6B-AS1 overexpression group and empty plasmid group(NC group).The cell model was divided into the empty plasmid group(NC group)and OTUD6B-AS1 overexpression group.The transfection efficiency of OTUD6B-AS1 mRNA was verified through qRT-PCR.The CCK-8 experiment was used to detect the effect of OTUD6B-AS1 on the proliferation activity of lung adenocarcinoma cells,and the Transwell assay was used to detect the effect of OTUD6B-AS1 on the migration and invasion ability of lung adenocarcinoma cells. Results Compared to the NC group,the overexpression OTUD6B-AS1 group had a significant increase in the expression of OTUD6B-AS1(P＜0.05).The CCK-8 assay results showed that the proliferation activity of A549 cells in the OTUD6B-AS1 overexpression group was significantly reduced compared to the NC group(P＜0.05).The results of the Transwell assay showed that the OTUD6B-AS1 overexpression group had significantly lower cell migration and invasion abilities than the NC group(P＜0.05). Conclusion Overexpression lncRNA OTUD6B-AS1 in lung adenocarcinoma A549 cells can significantly inhibit the proliferation,migration,and invasion ability of A549 cells.

Objective The aim of this study was to investigate the molecular regulatory mechanism of cancer susceptibility candidate 15 (CASC15),a long-stranded non-coding RNA (lncRNA),in hepatocellular carcinoma (HCC). Methods Bioinformatics methods were used to predict the expression of target genes and analyze the relationship between the expression of target genes and the survival time of patients;Hepatocellular carcinoma tissues and adjacent tissues from patients with HCC were collected;CCK-8,Transwell,and flow cytometry experiments were used to detect proliferation,invasion,migration and apoptosis of SMMC7721 cells and Huh-7 cells;The dual-luciferase assay was used to detect the targeting relationship between miR-144-3p and CASC15,as well as leucine rich repeat containing protein 1 (LRRC1);RT-qPCR and Western blot were used to detect mRNA and protein expression of target genes;Immunofluorescence was used for protein localization of target genes;Replicate experiment was performed to verify the effect of CASC15/miR-144-3p/LRRC1 on the progression of HCC.In vivo experiment was performed to verify the effect of CASC15 on HCC progression. Results TCGA database and RT-qPCR assay showed high expression of CASC15,low expression of miR-144-3p,and high expression of LRRC1 in HCC tissues and cells (P＜0.05).The results of cell function experiments on proliferation,invasion and migration showed that CASC15 and LRRC1 played a promoting role in tumor development,while miR-144-3p had an inhibitory effect,consistent with the results of apoptosis experiments (P＜0.05).Cell function experiments showed that CASC15 inhibited miR-144-3p function,miR-144-3p inhibited LRRC1,and CASC15 bound to miR-144-3p,leading to the upregulation of LRRC1.The replicate experimental results indicated that CASC15 promoted LRRC1 expression through inhibiting miR-144-3p,thereby promoting HCC cell proliferation,invasion and migration,and inhibiting apoptosis. Conclusion CASC15 may promote HCC progression by regulating the miR-144-3p/LRRC1 axis.

Objective The objective of this study was to investigate the expression of interleukin-38(IL-38)in patients with breast cancer and its regulatory function to CD8⁺T cell activity. Methods 44 patients with breast cancer,25 patients with benign breast tumor,and 20 controls,who were treated in the First Affiliated Hospital of Xinxiang Medical University from July 2020 and September 2022.Mononuclear cells from plasma and peripheral blood of all subjects were isolated,tumor-infiltrating lymphocytes from tumor tissues of breast cancer patients were isolated,and CD8⁺T cells were purified.IL-38 protein level in the plasma was measured by enzyme-linked immunosorbent assay(ELISA).The relative level of IL-38 mRNA in the tissue was semi-quantified by real-time quantitative PCR.Recombinant human IL-38 was used to stimulate CD8⁺T cells from peripheral blood and tumor tissue from patients with breast cancer.A co-culture system was established between CD8⁺T cells and breast cancer MCF-7 cell line.The percentage of target cell death was calculated by measuring lactate dehydrogenase level in the supernatants.The levels of perforin,granzyme B,interferon-γ and tumor necrosis factor-α(TNF-α)in the supernatants were measured by ELISA.The immune checkpoint molecules expression in CD8⁺T cells were detected by flow cytometry. Results The levels of plasma IL-38 were significantly higher in patients with breast cancer(74.23±19.88pg/mL)compared with in patients with benign breast tumor(62.87±16.27pg/mL,P=0.018)and controls(61.77±12.75pg/mL,P=0.013).The relative expression of IL-38 mRNA in tumor tissues was significantly higher than in para-tumor tissues(1.57±0.22 vs. 1.00±0.18,P＜0.001).The proportion of target cell death induced by peripheral and tumor-infiltrating CD8⁺T cells,and the levels of perforin and granzyme B secretion in direct contact co-culture group were higher than those in indirect contact co-culture group(P＜0.05).There were no significant differences of either interferon-γ or TNF-α levels between direct contact and indirect contact co-culture group(P＞0.05).In the direct contact co-culture group,the levels of target cell death proportion,perforin,granzyme B,interferon-γ and TNF-α l in the IL-38 stimulation group were lower than those in the non-stimulation group(P＜0.05).In the indirect contact co-culture group,the target of cell death proportion,interferon-γ and TNF-α the IL-38 stimulation group were also lower than those in the non-stimulation group(P＜0.05).However,there were no statistical differences of either perforin or granzyme B levels between the IL-38 stimulation group and non-stimulation group within the indirect contact co-culture group(P＞0.05).There were also no differences in the levels of immune checkpoint molecules in CD8⁺T cells between the non-stimulation group and the IL-38 stimulation group(P＞0.05). Conclusion Highly expressed IL-38 in patients with breast cancer may be involved in inducing CD8⁺T cell functional failure.

Objective The aim of this study was to explore the application of baseline neutrophil-lymphocyte ratio(NLR),platelet count-lymphocyte ratio(PLR),monocyte-lymphocyte ratio(MLR),and pan-immune inflammation value(PIV)in the use of PD-1 inhibitors combined with chemotherapy in advanced non-small cell lung cancer(NSCLC),and establish a prognosis-related nomogram model. Methods The clinical data of 77 patients with driver gene-negative advanced NSCLC who received first-line PD-1 inhibitor combined with chemotherapy at Harbin Medical University Cancer Hospital from January 2019 to January 2021 were retrospectively analyzed.Univariate and multivariate Cox regression analysis were used to determine the independent prognostic factors of progression-free survival(PFS);A prognostic-related nomogram model was established,and the accuracy of prediction model was evaluated through consistency index. Results Multivariate Cox regression analyses showed that MLR,PIV,brain metastasis,and pleural metastasis were independent factors affecting PFS in patients with driver gene-negative advanced NSCLC(P＜0.05).The nomogram prognostic model constructed based on the Cox regression results had a good predictive ability(C-index value was 0.786,95% CI:0.721-0.851).The ROC curve showed that the combined effect of MLR and PIV in detecting the prognosis of PFS(AUC=0.717,P=0.001)was better than that of MLR(AUC=0.643)and PIV(AUC=0.640). Conclusion MLR,PIV,brain metastasis,and pleural metastasis can predict the prognosis of driver gene-negative advanced NSCLC patients treated with first-line chemotherapy combined with PD-1 inhibitors.The established nomogram model has high accuracy and clinical practicability.The predictive performance of combined detection of MLR and PIV may be better than that of separate detection of MLR and PIV.
