Oxidative stress and lipotoxicity [PDF]

Journal of Lipid Research, 2016
The α,β polyunsaturated lipid aldehydes are potent lipid electrophiles that covalently modify lipids, proteins, and nucleic acids. Recent work highlights the critical role these lipids play under both physiological and pathological conditions. Protein carbonylation resulting from nucleophilic attack of lysine, histidine, and cysteine residues is a ...

Lipotoxicity [PDF]

Kidney International, 2006
Excess fatty acids accompanied by triglyceride accumulation in parenchymal cells of multiple tissues including skeletal and cardiac myocytes, hepatocytes, and pancreatic beta cells results in chronic cellular dysfunction and injury. The process, now termed lipotoxicity, can account for many manifestations of the 'metabolic syndrome'.

Mitochondrial stress in advanced fibrosis and cirrhosis associated with chronic hepatitis B, chronic hepatitis C, or nonalcoholic steatohepatitis

Hepatology, EarlyView., 2022
Adaptive mitochondrial mechanisms allow mitochondrial resilience and prevent the worsening of fibrosis, while deregulation of these mechanisms promotes the progression from no/minimal‐mild (F0‐F2) fibrosis to advanced fibrosis and cirrhosis (F3‐F4). Abstract Background and Aims Hepatitis B virus (HBV) infection causes oxidative stress (OS) and alters ...

Lysosomal Ca2+ as a mediator of palmitate-induced lipotoxicity

Cell Death Discovery, 2023
While the mechanism of lipotoxicity by palmitic acid (PA), an effector of metabolic stress in vitro and in vivo, has been extensively investigated, molecular details of lipotoxicity are still not fully characterized. Since recent studies reported that PA

RIPK3 dampens mitochondrial bioenergetics and lipid droplet dynamics in metabolic liver disease

Hepatology, EarlyView., 2022
RIPK3 dampens mitochondrial bioenergetics and lipid droplet dynamics in metabolic liver disease. Abstract Background and Aims Receptor‐interacting protein kinase 3 (RIPK3) mediates NAFLD progression, but its metabolic function is unclear. Here, we aimed to investigate the role of RIPK3 in modulating mitochondria function, coupled with lipid droplet (LD)

Lipotoxicity in the liver

World Journal of Hepatology, 2013
Obesity due to excessive food intake and the lack of physical activity is becoming one of the most serious public health problems of the 21(st) century. With the increasing prevalence of obesity, non-alcoholic fatty liver disease is also emerging as a pandemic.

Nicotinamide riboside and pterostilbene reduces markers of hepatic inflammation in NAFLD: A double‐blind, placebo‐controlled clinical trial

Hepatology, EarlyView., 2022
NRPT 1X reduces ALT and ceramide 14:0 in 65% of subjects as compared to only 28% in the placebo group. Abstract Background and Aims The prevalence of NAFLD is increasing globally and on a path to becoming the most frequent cause of chronic liver disease. Strategies for the prevention and treatment of NAFLD are urgently needed.

Lipotoxicity in NASH

Journal of Hepatology, 2012
Exposure to a sedentary lifestyle, fat-rich and fiber-poor diets, positive caloric imbalance and an extended life disrupt the metabolic homeostasis causing non-alcoholic fatty liver disease. A subset of patients with this emerging public health problem may develop non-alcoholic steatohepatitis (NASH) and progress to cirrhosis and liver cancer [1 ...

Lipotoxicity-related sarcopenia: a review

Journal of Medicine and Life, 2022
A body of literature supports the postulation that a persistent lipid metabolic imbalance causes lipotoxicity, “an abnormal fat storage in the peripheral organs”. Hence, lipotoxicity could somewhat explain the process of sarcopenia, an aging-related, gradual, and involuntary decline in skeletal muscle strength and mass associated with several health ...

Beta cell lipotoxicity in the development of type 2 diabetes: the need for species-specific understanding

Frontiers in Endocrinology, 2023
The propensity to develop type 2 diabetes (T2D) is known to have both environmental and hereditary components. In those with a genetic predisposition to T2D, it is widely believed that elevated concentrations of circulatory long-chain fatty acids (LC-FFA)
