Hepatocellular carcinoma (HCC) is a deadly tumor with high heterogeneity. Aerobic glycolysis is a common indicator of tumor growth and plays a key role in tumorigenesis. Heterogeneity in distinct metabolic pathways can be used to stratify HCC into clinically relevant subgroups, but these have not yet been well-established. In this study, we constructed a model called aerobic glycolysis index (AGI) as a marker of aerobic glycolysis using genomic data of hepatocellular carcinoma from The Cancer Genome Atlas (TCGA) project. Our results showed that this parameter inferred enhanced aerobic glycolysis activity in tumor tissues. Furthermore, high AGI is associated with poor tumor differentiation and advanced stages and could predict poor prognosis including reduced overall survival and disease-free survival. More importantly, the AGI could accurately predict tumor sensitivity to Sorafenib therapy. Therefore, the AGI may be a promising biomarker that can accurately stratify patients and improve their treatment efficacy.

Department of Pathology, Xingtai Medical College, Xingtai, China.
Objective: Oral squamous cell carcinoma (OSCC) is a common malignant tumor worldwide. Surfeit 4 (SURF4) is a member of the surfeit gene family and plays a regulatory role in various cellular processes, such as protein transport and lipid metabolism. Therefore, this study aims to investigate the regulatory role and mechanisms of SURF4 in OSCC.

The Warburg effect, also known as 'aerobic' glycolysis, describes the preference of cancer cells to favor glycolysis over oxidative phosphorylation for energy (adenosine triphosphate-ATP) production, despite having high amounts of oxygen and fully active mitochondria, a phenomenon first identified by Otto Warburg. This metabolic pathway is traditionally viewed as a hallmark of cancer, supporting rapid growth and proliferation by supplying energy and biosynthetic precursors. However, emerging research indicates that the Warburg effect is not just a strategy for cancer cells to proliferate at higher rates compared to normal cells; thus, it should not be considered an 'enemy' since it also plays complex roles in normal cellular functions and/or under stress conditions, prompting a reconsideration of its purely detrimental characterization.

Physical exercise is beneficial to keep physical and mental health. The molecular mechanisms underlying exercise are still worth exploring. The healthy adult mice after six weeks of moderate-intensity exercise (experimental group) and sedentary mice (control group) were used to perform transcriptomic, proteomic, lactylation modification, and metabolomics analysis.

Backgroud: Recent studies have reported mitochondrial damage and metabolic dysregulation in BPD, but the changes in mitochondrial dynamics and glucose metabolic reprogramming in ATII cells and their regulatory relationship have not been reported.
Methods: Neonatal rats in this study were divided into model (FIO2:85%) and control (FIO2: 21%) groups. Lung tissues were extracted at 3, 7, 10 and 14 postnatal days and then conducted HE staining for histopathological observation.

Background And Purpose: Sepsis is a condition capable of causing systemic inflammation and metabolic reprogramming. Previous studies have shown that sinomenine (SIN) can mitigate sepsis by reducing inflammation, while the effect on metabolic reprogramming is unclear. The aim of this study is to investigate the function of SIN in metabolic reprogramming in sepsis.
