Glioblastoma (GBM) is the most common intracranial malignancy, but current treatment options are limited. Super-enhancers (SEs) have been found to drive the expression of key oncogenes in GBM. However, the role of SE-associated long non-coding RNAs (lncRNAs) in GBM remains poorly understood. Here, we screened for an up-regulated lncRNA-SLCO4A1-AS1 expressed in GBM by analyzing data from GSE54791, GSE4536 and TCGA. We systematically analyzed its relationship with clinical characteristics, prognosis, epigenetics, tumor microenvironment (TME), biological functions, and transcription factors. We found that SE-driven SLCO4A1-AS1 was significantly upregulated in GBM and correlated with poor prognosis. Knockdown of SLCO4A1-AS1 decreased glioma cell proliferation, invasive ability, self-renewal ability, and increased apoptosis. Epigenetic analysis revealed that SOX2 and SE could drive SLCO4A1-AS1 expression. In vitro experiments further demonstrated that GBM cells with high SLCO4A1-AS1 expression were more sensitive to VX-11e, and overexpression of SLCO4A1-AS1 could reverse the inhibitory effect of VX-11e on GBM cells. In conclusion, this study revealed that SE-driven SLCO4A1-AS1 may be a potential therapeutic target in GBM.

Extracorporeal membrane oxygenation (ECMO) is a technique used to support severe cardiopulmonary failure. Its potential life-saving benefits are tempered by the significant risk for acute brain injury (ABI), from both primary pathophysiologic factors and ECMO-related complications through central nervous system cellular injury, blood-brain barrier dysfunction (BBB), systemic inflammation and neuroinflammation, and coagulopathy. Plasma biomarkers are an emerging tool used to stratify risk for and diagnose ABI, and prognosticate neurofunctional outcomes.

Primary aldosteronism (PA) is a common, salt-sensitive form of endocrine hypertension. Compared with essential hypertension (EH), PA is more susceptible to cardiorenal complications and metabolic risks. However, PA has a low screening rate and a poor response to mineralocorticoid receptor antagonists (MRAs).

Objectives: Cancer-related cachexia affects approximately 50% to 80% of cancer patients and contributes significantly to cancer-related mortality, accounting for 20% of deaths. This multifactorial syndrome is characterized by systemic inflammation, anorexia, and elevated energy expenditure, leading to severe weight loss and muscle wasting. Understanding the underlying mechanisms is critical for developing effective interventions.

Background And Study Aims: This study was aimed to validate the correlation of circular RNA HIPK3 (CircHIPK3) expression in serum and tissues with the progression of liver fibrosis (LF) and liver cirrhosis (LC).
Patients And Methods: Serum CircHIPK3 expressions were detected in 120 patients with LF/LC and 120 healthy controls (HCs). CircHIPK3 expression in tissues was detected in 120 fibrotic liver tissues and compared to 57 healthy liver tissues from patients with hepatic hemangioma.

Personalized medicine is an emerging field that provides novel approaches to disease's early diagnosis, prevention, treatment, and prognosis based on the patient's criteria in gene expression, environmental factors, lifestyle, and diet. To date, hepatocellular carcinoma (HCC) is a significant global health burden, with an increasing incidence and significant death rates, despite advancements in surveillance, diagnosis, and therapeutic approaches. The majority of HCC lesions develop in patients with liver cirrhosis, carrying the risks of mortality associated with both the tumor burden and the cirrhosis.
