Advancing de novo lipogenesis: Genetic and metabolic insights.

De novo lipogenesis (DNL) is the process whereby cells synthesize fatty acids from acetyl-CoA, contributing to steatosis in fatty liver disease. Two new studies, using genetic mouse models, metabolomics, and pharmacology, identified alternative pathways in DNL and unexpected physiological effects when targeting key enzymes in this pathway.

Glycerol-3-phosphate activates ChREBP, FGF21 transcription and lipogenesis in Citrin Deficiency.

Citrin Deficiency (CD) is caused by inactivation of SLC25A13, a mitochondrial membrane protein required to move electrons from cytosolic NADH to the mitochondrial matrix in hepatocytes. People with CD do not like sweets. We discovered that SLC25A13 loss causes accumulation of glycerol-3-phosphate (G3P), which activates carbohydrate response element binding protein (ChREBP) to transcribe FGF21, which acts in the brain to restrain intake of sweets and alcohol, and to transcribe key genes of lipogenesis.

Sex-Specific Effects in Acute Nicotine Vapor Exposure on Binge Drinking and Activity in the Central Amygdala and Ventral Tegmental Area.

Introduction: The increasing prevalence of electronic nicotine delivery systems and alcohol drinking has led to increases in nicotine and alcohol co-use. However, the impact of ENDs on brain activity and binge drinking behavior is not fully understood.

Aims And Methods: We subjected female and male C57BL/6J mice to a voluntary drinking and electronic nicotine vapor exposure paradigm.

The double life of glucose metabolism: brain health, glycemic homeostasis, and your patients with type 2 diabetes.

The maintenance of cognitive function is essential for quality of life and health outcomes in later years. Cognitive impairment, however, remains an undervalued long-term complication of type 2 diabetes by patients and providers alike. The burden of sustained hyperglycemia includes not only cognitive deficits but also the onset and progression of dementia-related conditions, including Alzheimer's disease (AD).

Impact of the International Tumor Budding Consensus Conference Recommendations in Oral Cancer.

Objectives: Tumor budding was suggested as a valuable prognostic factor in oral squamous cell carcinoma (OSCC) but lacks a standardized scoring system. This study evaluates tumor budding in OSCC using the scoring system recommended by the International Tumor Budding Consensus Conference (ITBCC) 2016.

Materials And Methods: The study included 114 patients with resected OSCC.
