Lipid Unsaturation Promotes Bax and Bak Pore Activity During Apoptosis

Unsaturation of Fatty Acids Promotes Pore-Forming Activity of Bax and Bak in Apoptosis Background Apoptosis is the major form of programmed cell death, involved in fundamental biological processes such as embryonic development, tissue homeostasis, and immune system functions. Dysregulation of apoptosis can lead to neurodegenerative diseases and tum...

Orthogonal proteogenomic analysis identifies the druggable PA2G4-MYC axis in 3q26 AML

Orthogonal Proteogenomic Analysis Identifies Druggable PA2G4-MYC Axis in 3q26 AML Acute myeloid leukemia (AML) is a highly heterogeneous and aggressive malignancy. In particular, the 3q26 chromosomal abnormality subtype of AML has a complex pathogenic mechanism and lacks effective targeted therapies. To address this challenge, Matteo Marchesini and...

Inhibition of Fatty Acid Uptake by TGR5 Prevents Diabetic Cardiomyopathy

Preventing Diabetic Cardiomyopathy through Suppressing TGR5-Mediated Fatty Acid Uptake Background and Problem Statement Diabetic Cardiomyopathy (DBCM) is a severe complication frequently faced by diabetic patients, characterized by lipid accumulation in the myocardium and cardiac dysfunction. Bile acid metabolism plays a crucial role in cardiovascu...

The Microbial Metabolite Agmatine Acts as an FXR Agonist to Promote Polycystic Ovary Syndrome in Female Mice

Microbial Metabolite Ethylamine as FXR Agonist Promotes Polycystic Ovary Syndrome in Female Mice I. Research Background and Objectives Polycystic ovary syndrome (PCOS) is a common endocrine and metabolic disorder affecting 6%-20% of women of reproductive age worldwide. Symptoms of PCOS include hyperandrogenemia, ovarian dysfunction, and polycystic ...

Acetate Reprogrammes Tumour Metabolism and Promotes PD-L1 Expression and Immune Evasion by Upregulating c-Myc

Acetate Reprogrammes Tumour Metabolism and Promotes PD-L1 Expression and Immune Evasion by Upregulating c-Myc

Acetate Reprograms Tumor Metabolism and Promotes Immune Evasion and PD-L1 Expression by Upregulating c-myc Introduction Reprogramming of tumor metabolism is of great significance in cancer research, and acetate plays a crucial role in this process. In tumor cells, acetate is an important precursor of acetyl-CoA, which is used for energy production,...

Weak Neuronal Glycolysis Sustains Cognition and Organismal Fitness

This paper aims to explore the physiological importance of glycolysis in neuronal metabolic processes. For a long time, although neuronal activity mainly relies on glucose for energy, neurons have relatively weak glucose metabolism, mainly through glycolysis rather than other metabolic pathways. This phenomenon can be attributed to the sustained de...

Hippo-Yap/Taz Signalling Coordinates Adipose Plasticity and Energy Balance by Uncoupling Leptin Expression from Fat Mass

The Coordinating Role of the Hippo-YAP/TAZ Pathway in Adipose Plasticity and Energy Balance Adipose tissue not only serves as an energy storage depot but also functions as an endocrine organ. However, the mechanisms coordinating these functions remain elusive. This study unveiled that the transcriptional co-regulators YAP and TAZ maintain metabolic...

PNPO-PLP Axis Senses Prolonged Hypoxia in Macrophages by Regulating Lysosomal Activity

Oxygen is an essential substance for all metazoan organisms on Earth, influencing biological processes under various physiological and pathological conditions. Although systems that induce acute hypoxic responses, including the hypoxia-inducible factor (HIF) pathway, have been identified, their mechanisms of action under prolonged hypoxia remain in...
