Background: BIRC5 is associated with the prognosis of a variety of tumors. This meta-analysis aimed to identify whether BIRC5 is associated with the prognosis of lung adenocarcinoma (LUAD).
Research Design And Methods: We conducted an in-depth review of seven Chinese and English databases and two high-throughput sequencing databases according to inclusion and exclusion criteria to find relevant studies. The pooled standardized mean differences (SMDs) and 95% confidence intervals (CIs) for the associations between the BIRC5 expression level and clinicopathological characteristics were calculated, and the pooled hazard ratios (HRs) and 95% CIs were calculated to estimate associations between the BIRC5 expression level and survival outcomes.
Results: In total, 17 studies involving 2887 LUAD patients whose BIRC5 expression level was known were included in this meta-analysis. The BIRC5 expression level was higher in younger patients, males, and smokers and correlated with advanced AJCC, T and N stages but not M stage. A high BIRC5 expression level also correlated with poor overall survival (OS) and progression-free survival (PFS). There was no publication bias in this study.
Conclusions: This meta-analysis indicates that BIRC5 is a significant biomarker for a poor prognosis and poor clinicopathological outcomes in patients with LUAD.

Background: Lung cancer is a highly aggressive tumor with limited therapeutic options. The misregulation of Androgen Receptor (AR) signaling has been observed in lung cancer. Therefore, inhibiting AR signaling is a promising strategy for treating lung cancer.

Clustered regularly interspaced short palindromic repeats (CRISPR)-associated nuclease 9 (CRISPR/Cas9) offers a robust approach for genome manipulation, particularly in cancer therapy. Given its high expression in triple-negative breast cancer (TNBC), targeting with CRISPR/Cas9 holds promise as a therapeutic strategy. The aim of this study was to design specific single guide ribonucleic acid (sgRNA) for CRISPR/Cas9 to permanently knock out the gene, exploring its potential as a therapeutic approach in breast cancer while addressing potential off-target effects.

Background: Bioinformatics analysis of hepatocellular carcinoma (HCC) expression profiles can aid in understanding its molecular mechanisms and identifying new targets for diagnosis and treatment.
Aim: In this study, we analyzed expression profile datasets and miRNA expression profiles related to HCC from the GEO using R software to detect differentially expressed genes (DEGs) and differentially expressed miRNAs (DEmiRs).
Methods And Results: Common DEGs were identified, and a PPI network was constructed using the STRING database and Cytoscape software to identify hub genes.

Wanxi white goose is an important male parent in crossbreeding of Chinese geese, but its short reproductive cycle restricts its application in Northeast China. Therefore, understanding the potential mechanism of breeding period regulation in Wanxi white goose will help to provide more options for crossbreeding. In this study, the reproductive period was divided into prophase (T1), metaphase (T2) and anaphase (T3) according to the laying rhythm of geese.

Objective To investigate the effects of evodiamine (EVO) on Natural Killer (NK) cell-mediated killing in small cell lung cancer (SCLC) cells via affecting baculoviral inhibitor of apoptosis repeat containing 5 (BIRC5). Methods H446 cells and NK-92 cells were treated with EVO at different concentrations, and cell proliferation was detected using the MTT (3-(4, 5-Dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide) assay, while cell invasion was assessed using the Transwell assay. NK-92 cells and H446 cells were co-cultured at different effector-to-target ratios to detect the cytotoxicity of NK cells against H446 cells and the level of degranulation in NK-92 cells.
