Demethylzeylasteral targets lactate by inhibiting histone lactylation to suppress the tumorigenicity of liver cancer stem cells.

Cancer stem cells drive tumor initiation, progression, and recurrence, which compromise the effectiveness of anti-tumor drugs. Here, we report that demethylzeylasteral (DML), a triterpene anti-tumor compound, suppressed tumorigenesis of liver cancer stem cells (LCSCs) by interfering with lactylation of a metabolic stress-related histone. Using RNA sequencing (RNA-seq) and gas chromatography-mass spectrometric (GC-MS) analysis, we showed that the glycolysis metabolic pathway contributed to the anti-tumor effects of DML, and then focused on lactate downstream regulation as the molecular target.

The immune regulation of BCL3 in glioblastoma with mutated IDH1.

Background: Glioblastoma in the brain is the most malignant solid tumor with a poor prognosis. Screening critical targets and exploring underlying mechanisms will be a benefit for diagnoses and treatment. IDH1 mutation (R132) was used to distinguish glioblastoma grade and predict prognosis as a significant marker.

A Hypoxia-Related Long Non-Coding RNAs Signature Associated With Prognosis in Lower-Grade Glioma.

Accumulating evidence suggests that hypoxia microenvironment and long non-coding lncRNAs (lncRNAs) exert critical roles in tumor development. Herein, we aim to develop a hypoxia-related lncRNA (HRL) model to predict the survival outcomes of patient with lower-grade glioma (LGG). The RNA-sequencing data of 505 LGG samples were acquired from The Cancer Genome Atlas (TCGA).

Relationships among lymphocyte subsets, cytokines, and the pulmonary inflammation index in coronavirus (COVID-19) infected patients.

We explored the relationships between lymphocyte subsets, cytokines, pulmonary inflammation index (PII) and disease evolution in patients with (corona virus disease 2019) COVID-19. A total of 123 patients with COVID-19 were divided into mild and severe groups. Lymphocyte subsets and cytokines were detected on the first day of hospital admission and lung computed tomography results were quantified by PII.

Adherence to the dietary approaches to stop hypertension diet and risk of stroke: A meta-analysis of prospective studies.

The Dietary Approaches to Stop Hypertension (DASH) diet has been shown to lower the risk of hypertension, but its role in the prevention of stroke remains in debate. We therefore conducted a meta-analysis to examine the association between DASH diet and incident stroke.A systematic database search in PubMed and Embase was performed to identify eligible prospective studies.
