[PMID: 39006253 PMCID: PMC11236635 DOI: 10.62347/tpcm6776] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/14/2024] [Accepted: 05/20/2024] [Indexed: 07/16/2024]
Abstract
AIM To explore the impact of up- or down-regulation of Neurofibromin 2 (NF2) on the expression of downstream Hippo pathway genes, large tumor suppressor gene1 (LATS1), and phosphorylation of Mammalian Ste2-like kinases1/2 (MST1/2), in lung cancer cells. METHODS A549 lung cancer cells were used. The NF2 was down-regulated by si-RNA interference and upregulated by lentiviral vector mediated overexpression. The LATS1 and MST1/2 expressions were evaluated by real-time PCR and western blot. RESULTS Down-regulation of NF2 decreased LATS1 and MST1/2 level (P<0.05). Overexpression of NF2 increased LATS1 (P<0.05) and Mammalian Ste2-like kinases1 (MST1) (P<0.05), suggesting LATS1 and MST1 are modulated by NF2 in a lung cancer cell line. CONCLUSIONS NF2 mediates the downstream LATS1 and MST1/2 expressions in a lung cancer cell line.

Abstract
Despite the abundance of genotype-phenotype association studies, the resulting association outcomes often lack robustness and interpretations. To address these challenges, we introduce PheSeq, a Bayesian deep learning model that enhances and interprets association studies through the integration and perception of phenotype descriptions. By implementing the PheSeq model in three case studies on Alzheimer's disease, breast cancer, and lung cancer, we identify 1024 priority genes for Alzheimer's disease and 818 and 566 genes for breast cancer and lung cancer, respectively. Benefiting from data fusion, these findings represent moderate positive rates, high recall rates, and interpretation in gene-disease association studies.

Abstract
The present study aimed to investigate the expression of long non-coding RNA (lncRNA) cyclin dependent kinase inhibitor-2B-antisense RNA 1 CDKN2B-AS1 in patients with peripheral blood of idiopathic pulmonary fibrosis (IPF). A total of 24 patients with IPF and 24 healthy controls were included in the study, four patients with IPF and four healthy controls were selected randomly to extract RNA. There were no other diseases such as hypertension and diabetes in the two groups. RNA from peripheral blood was extracted by high-throughput sequencing and bioinformatics analysis was performed. Based on selected differentially expressed lncRNA and mRNA, gene ontology analysis was performed to screen out the tumor-associated mRNA. A total of 20 samples were chosen to avoid variance due to individual differences. A total of 20 patients with IPF, and 20 controls were further studied, RNA extracted from peripheral blood was used to verify the lncRNA and mRNA levels. A total of 440 lncRNAs were identified to be upregulated and 1,376 downregulated according to the screening results of differential expression. High-throughput sequencing and bioinformatics analysis demonstrated that the expression of CDKN2B-AS1 decreased significantly in patients with IPF compared with healthy controls. The adjacent gene mRNA of CDKN2B-AS1 was identified as CDKN2A, an important anti-oncogene, which is concentrated on the p53 signaling-pathway according to the Kyoto Encyclopedia of Genes and Genomes database. CDKN2A mRNA expression levels were lower in patients with IPF and higher in the control group. The expression of CDKN2B-AS1 and CDKN2A mRNA was significantly lower in IPF group compared with in the control group (P<0.05). The results suggest the expression of the CDKN2B-AS1 and adjacent gene, CDKN2A, are downregulated in the peripheral blood of patients with IPF, which activates the p53-signaling pathway to promote lung cancer formation.

Exp Ther Med 2016; 11:98-100.

Abstract
The pathogenesis of lung cancer has not been fully elucidated and biological markers acting as predictors of tumor evolution and aggressiveness remain unidentified. The multi-step hypothesis, suggesting a progression from adenomatous hyperplasia (AAH) to adenocarcinoma (AC) through bronchioalveolar carcinoma (BAC), was highlighted in a previous cytogenetic study performed in a single case. The present study reports the results of an array-comparative genomic hybridization (a-CGH) analysis performed on the DNA obtained from the previously reported case that presented AAH, BAC and AC in one lung. The a-CGH results confirm and support the previous cytogenetic observations with new data, clearly supporting the hypothesis of a multi-step carcinogenic process in the lung.

Abstract
MicroRNAs are a family of small non-coding RNAs that constitute a prevalent gene regulation. In this study, we showed the expression of miR-512-5p is downregulated in non-small cell lung cancer (NSCLC) patient tumor samples compared to its paired normal lung tissues. Moreover, expression of miR-512-5p was increased by retinoic acid treatment. Overexpression of miR-512-5p induced apoptosis of NSCLC cell lines A549 and H1299, and miR-512-5p inhibitor reversed this effect in H1299 cells stably expressing miR-512. miR-512-5p inhibited glycolysis and migration in NSCLC cells, but shows no effect on cell proliferation. We identified p21 as a target gene of miR-512-5p. Overexpression of miR-512-5p led to the decrease of p21 protein and mRNA level. Knockdown of p21 resulted in similar effects on apoptosis and glycolysis as that observed of miR-512-5p overexpression, as well as rescued the effect of miR-512-5p inhibitor on cell apoptosis in H1299 cells stably expressing miR-512. In conclusion, our present study revealed miR-512-5p was able to target p21 to induce apoptosis and inhibit glycolysis in A549 and H1299 cell lines.
