Objective Using the TCGA database to explore the prognostic effects of DNA methylation sites on lung adenocarcinoma. Methods TCGA database was used to collecting DNA methylation data, gene expression data and clinical data of lung adenocarcinoma patients. The population were divided into the exploratory group and the validation group. The LASSO regression analysis was used to screen the methylation sites associated with the prognosis of lung adenocarcinoma in the exploratory group. Receiver operating characteristic curve was used to evaluate the prediction effect of the model, and further verified in the validation population. Results A total of 158 methylation sites with differential expression and significant correlation with the mRNA expression of the corresponding gene were screened from the TCGA database. With LASSO regression analysis, the DNA methylation sites associated with prognosis of lung adenocarcinoma were cg19378330. Those patients with levels above the median methylation site were assigned to the high-risk group, while those with levels below the median methylation site were assigned to the low-risk group. Patients' death risk in the high-risk group were 38% higher than those in the low-risk group (OR=1.38, 95%CI=1.16-2.69). The area under the curve was 0.80 (95%CI=0.73-0.88) and the sensitivity was 86.2% in the exploratory stage population.Similar results were seen in the validation population. Conclusions The DNA methylation site cg19378330 was significantly associated withthe prognosisof lung adenocarcinoma, and could effectively predict the risk of lung adenocarcinoma.

Objective To explore the prognostic significance of ferroptosis related lncRNAs in patients with lung squamous cell carcinoma. Methods Data of 551 lung squamous cell carcinoma cases was downloaded from the Cancer Genome Atlas (TCGA) of the United States, including 49 normal control samples and 502 lung squamous cell carcinoma samples. The lncRNAs co-expressed with genes related to ferroptosis was screened out. Univariate Cox regression was used to further screen out the lncRNAs. Then, Lasso regression and multiple Cox regression were used to construct lncRNA models related to ferroptosis. A model-based risk score system was established and Cox regression was used to test whether it was an independent prognostic factor. The functional enrichment of ferroptosis related lncRNAs were visualized using Gene Ontology and Kyoto Encyclopedia of Genes and Genomes. Results The four prognostic ferroptosis related lncRNAs (AC253536.6, FLJ46906 LUCAT, AC022150.2) were significantly different, and the ferroptosis lncRNAs model was constrncted with them. This model divided lung squamous cell carcinoma patients into low-risk group and high-risk group. The model-based risk score was a significant independent factor for patients with lung squamous cell carcinoma (HR=2.116, 95% CI=1.513-2.961; P<0.001). In addition, the four lncRNAs were significantly enriched in metabolism and tumor classical pathways during the ferroptosis process. Conclusions The four ferroptosis lncRNAs could be molecular biomarkers and therapeutic targets for patients with lung squamous cell carcinoma.

Objectives To investigate the influence of thyroid function and related factors on blood lipid levels in patients with papillary thyroid cancer under short-term severe hypothyroidism. Methods Sixty-one patients with papillary thyroid carcinoma diagnosed by pathology were included. The data of thyroid function and blood lipid levels of all patients before operation and iodine treatment were collected. The effects of gender, age, operation mode, lymph node metastasis and other related factors on blood lipid were compared. Results Before iodine treatment, all blood lipid indexes were higher than the baseline level before operation. The levels of total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), apolipoprotein A1 (APO-A1), apolipoprotein B (APO-B), lipoproteins (LP) in the thyroid stimulating hormone (TSH)>60 mIU/L group were significantly higher than those in the TSH≤60 mIU/L group.Triglyceride (TG) and arteriosclerosis index (AI) levels were significantly lower in female patients compared with male patients, HDL-C and APO-A1 levels were lower in male patients compared with female patients, and TC levels were higher in patients aged>45 compared with those aged≤45, with significant differences (all P<0.05). No significant differences were observed in lipid levels among the different surgical procedures and lymph node metastasis subgroups (P>0.05). TC levels were negatively correlated with free triiodothyronines (FT3), free thyroxine (FT4), thyroxine (T4) levels (r=-0.342,-0.370,-0.340,respectively). HDL-C, LDL-C, and APO-B levels were negatively correlated with T4 levels (r=-0.294, -0.354, -0.324,respectively), APO-A1 levels were negatively correlated with FT4, triiodothyronine (T3), T4 levels (r=-0.306,-0.262,-0.263,respectively), and LP levels were negatively correlated with T3 and T4 levels (r=-0.268,-0.313, respectively). Conclusions Short term hypothyroidism before iodine treatment for papillary thyroid cancer could lead to the increase of full set of blood lipid indexes, male patients and middle-aged and elderly patients could also be accompanied by higher blood lipid levels.

Objective To investigate the effects of different concentrations of sinomenine on proliferation, cell cycle and apoptosis of renal carcinoma cells. Methods The renal carcinoma cells were treated with different concentrations of sinomenine. MTS was used to analyze the effects of sinomenine on proliferation in 786-O renal carcinoma cells, the cell cycle changes were determined using flow cytometry, while the changes of apoptosis were detected by Annexin V-FITC / PI double staining. The expression of apoptosis-related proteins such as c-myc, Bax and Caspase-3 were detected by Western blot. Results Sinomenine significantly inhibited the proliferation of 786-O cells and induced cell cycle arrest and apoptosis in G1/S phase. With the increase of sinomenine concentration, the inhibition rate increased gradually. Sinomenine significantly down-regulated the expression of c-myc protein, while the expressions of the apoptotic protein Bax, Caspase-3 were up-regulated. Conclusions Sinomenine can significantly inhibit the expression of c-myc in 786-O cells, reduce proliferation ability, and induce cell cycle arrest and apoptosis. Sinomenine may have a potential therapeutic effect on renal cancer.

Objective To estimate the association between ABCC2 mRNA expression and the prognosis of lung adenocarcinoma and explore the potential influencing mechanism.Methods Difference analysis was used to evaluate the gene expression in tumor tissues and adjacent normal tissues based on The Cancer Genome Atlas database and Human Protein Atlas database.Multivariate COX regression and Kaplan-Meier analysis were performed to evaluate the association between ABCC2 gene expression and the prognosis of lung adenocarcinoma.Gene-set enrichment analysis (GSEA) was performed to screen differentially enriched pathways associated with the ABCC2 high expression phenotype.Results ABCC2 was overexpressed in lung adenocarcinoma tumor tissues compared with adjacent normal tissues.Kaplan-Meier survival analysis showed a significant relationship between ABCC2 mRNA expression and lung adenocarcinoma prognosis (HR=1.16,95% CI=1.09-1.95; P=0.010).Univariate and multivariate Cox regression analysis showed that ABCC2 mRNA expression was an independent risk factor affecting the survival of patients with lung adenocarcinoma.The results of GSEA suggested that ABCC2 may influence the development of lung adenocarcinoma by regulating the metabolism of targeted drug the treatment.Conclusions ABCC2 overexpression can significantly increase the risk of death in patients with lung adenocarcinoma,ABCC2 may be a potential molecular marker for poor prognosis in lung adenocarcinoma.
