However, lncRNA WEE2‑AS1 overexpression had no significant effect on cell cycle distribution compared with the negative control group. The western blotting results indicated that lncRNA WEE2‑AS1 knockdown significantly reduced the expression levels of phosphorylated cyclin dependent kinase 1, WEE1 homolog 2 and myelin transcription factor 1, but increased the expression level of cell division cycle 25B compared with the negative control group. lncRNA WEE2‑AS1 overexpression displayed the opposite effect on protein expression. Collectively, the present study suggested that lncRNA WEE2‑AS1 was significantly upregulated in ASO and may serve a role in regulating human vascular endothelial cell viability. Further investigation into lncRNA WEE2‑AS1 may broaden the current understanding of the molecular mechanism underlying ASO, and aid with the identification of specific probes and precise targeted drugs for the diagnosis and treatment of ASO.Ruptured intracranial aneurysm (IA)‑induced subarachnoid hemorrhage (SAH) triggers a series of immune responses and inflammation in the brain and body. INCB059872 ic50 The present study was conducted to identify additional circulating biomarkers that may serve as potential therapeutic targets for SAH‑induced inflammation. Differentially expressed (DE) long non‑coding RNAs (lncRNAs; DElncRNAs) and genes (DEGs) in the peripheral blood mononuclear cells between patients with IA rupture‑induced SAH and healthy controls were identified in the GSE36791 dataset. DEGs were used for weighted gene co‑expression network analysis (WGCNA), and SAH‑associated WGCNA modules were identified. Subsequently, an lncRNA‑mRNA regulatory network was constructed using the DEGs in SAH‑associated WGCNA modules. A total of 25 DElncRNAs and 1,979 DEGs were screened from patients with IA‑induced SAH in the GSE36791 dataset compared with the controls. A total of 11 WGCNA modules, including four upregulated modules significantly associated with IA rupture‑induced SAH were obtained. The DEGs in the SAH‑associated modules were associated with Gene Ontology biological processes such as 'regulation of programmed cell death', 'apoptosis' and 'immune response'. The subsequent lncRNA‑mRNA regulatory network included seven upregulated lncRNAs [HCG27, ZNFX1 antisense RNA 1, long intergenic non‑protein coding RNA (LINC)00265, murine retrovirus integration site 1 homolog‑antisense RNA 1, cytochrome P450 1B1‑AS1, LINC01347 and LINC02193] and 375 DEGs. Functional enrichment analysis and screening in the Comparative Toxicogenomics Database demonstrated that SAH‑associated DEGs, including neutrophil cytosolic factor (NCF)2 and NCF4, were enriched in 'chemokine signaling pathway' (hsa04062), 'leukocyte transendothelial migration' (hsa04670) and 'Fc gamma R‑mediated phagocytosis' (hsa04666). The upregulated lncRNAs and genes, including NCF2 and NCF4, in patients with IA rupture‑induced SAH indicated their respective potentials as anti‑inflammatory therapeutic targets.Sepsis is a serious clinical condition characterized by systemic inflammation. The long noncoding RNA (lncRNA) highly upregulated in liver cancer (HULC) was validated to partake in the development of sepsis. The present study aimed to investigate the potential mechanism of HULC in lipopolysaccharide (LPS)‑induced sepsis. Reverse transcription‑quantitative polymerase chain reaction (RT‑qPCR) and western blot analysis was employed to examine the expression of HULC, microRNA (miR)‑128‑3p, Rac family small GTPase 1 (RAC1) and pro‑inflammatory factors [IL‑6, TNF‑α, intercellular adhesion molecule (ICAM1) and vascular cell adhesion molecule (VCAM1)] in the serum of patients with sepsis or LPS‑induced human dermal microvascular endothelial cells (HMEC‑1). Flow cytometry and western blot assays were performed to detect cell apoptosis. The targeted relationship among HULC, miR‑128‑3p and RAC1 was confirmed by a dual‑luciferase reporter assay, RNA binding protein immunoprecipitation (RIP) assay and RNA pull‑down assay. HULC and RAC1 were found to be upregulated, and miR‑128‑3p was downregulated in the serum of patients with sepsis and LPS‑stimulated HMEC‑1 cells. LPS promoted apoptosis and inflammation, which were decreased by silencing of HULC. HULC targeted miR‑128‑3p and negatively regulated its expression. HULC knockdown protected HMEC‑1 cells from LPS‑induced injury by upregulating miR‑128‑3p. RAC1 was a target of miR‑128‑3p, and gain of RAC1 also relieved the silencing of HULC‑mediated suppressive effects on apoptosis and inflammation in LPS‑stimulated HMEC‑1 cells. In conclusion, HULC knockdown partially reversed LPS‑induced sepsis via the regulation of miR‑128‑3p/RAC1 axis.The altered expression of glycan antigens has been reported during cervix transformation, demonstrating increased mRNA levels of certain glycogenes. Human papillomavirus (HPV) is the aetiological agent of cervical cancer. High risk HPV E5 is considered an oncogene and has been implicated in cell transformation. E6 and E7 HPV oncoproteins modify the expression of certain glycogenes. The role of the E5 HPV protein in glycogene expression changes has not yet been reported. The aim of the present study was to determine the effects of HPV16 E5 oncoprotein on glycogene expression. For these, a microarray assay was performed using the HaCaT cell line and altered glycogenes were identified. The mRNA levels of certain glycogenes were determined via reverse transcription‑quantitative PCR (RT‑qPCR). Using in silico analysis, the present study identified that glycosylation pathways were altered by E5. Microarray analysis revealed alterations in certain glycogenes, including the upregulation of ST6GAL1, ST3GAL3, CHST2 and MANBA, and the downregulation of UGT2B15, GALNT11, NDST2 and UGT1A10. Increased mRNA levels were confirmed via RT‑qPCR for sialyltransferases genes. Additionally, in silico analysis was performed to identify glycosylation networks altered in the presence of the E5 oncoprotein. The analysis revealed that E5 could modify glycan sialylation, the N‑glycosylation pathway, keratan sulfate and glycosaminoglycan synthesis. To the best of our knowledge, the current study was the first to determine the role of the HPV16 E5 oncoprotein in glycogene expression changes. The results indicated that increased sialyltransferase mRNA levels reported in pre‑malignant and malignant cervical tissues could be the result of E5 oncoprotein expression. The results provide a possible role of HPV infection on glycosylation changes reported during cervix transformation.
