miR-873-5p targets mitochondrial GNMT-Complex II interface contributing to non-alcoholic fatty liver disease
(Elsevier, 2019-08-16)
Objective: Non-alcoholic fatly liver disease (NAFLD) is a complex pathology in which several dysfunctions, including alterations in metabolic pathways, mitochondrial functionality and unbalanced lipid import/export, lead ...
Atorvastatin Provides a New Lipidome Improving Early Regeneration After Partial Hepatectomy in Osteopontin Deficient Mice
(Nature Publishing Group, 2018-10-02)
Osteopontin (OPN), a multifunctional cytokine that controls liver glycerolipid metabolism, is involved in activation and proliferation of several liver cell types during regeneration, a condition of high metabolic demands. ...
Inhibition of ATG3 ameliorates liver steatosis by increasing mitochondrial function
(Elsevier, 2022-01)
[EN]Background & Aims: Autophagy-related gene 3 (ATG3) is an enzyme mainly known for its actions in the LC3 lipidation process, which is essential for autophagy. Whether ATG3 plays a role in lipid metabolism or contributes ...
Silencing hepatic MCJ attenuates non-alcoholic fatty liver disease (NAFLD) by increasing mitochondrial fatty acid oxidation
(Nature, 2020-07-03)
Nonalcoholic fatty liver disease (NAFLD) is considered the next major health epidemic with an estimated 25% worldwide prevalence. No drugs have yet been approved and NAFLD remains a major unmet need. Here, we identify MCJ ...
Magnesium Accumulation Upon Cyclin M4 Silencing Activates Microsomal Triglyceride Transfer Protein Improving NASH
(Elsevier, 2021-07)
Background & Aims: Perturbations of intracellular magnesium (Mg2+) homeostasis have implications for cell physiology. The cyclin M family, CNNM, perform key functions in the transport of Mg2+ across cell membranes. Herein, ...
Targeting UBC9-Mediated Protein Hyper-SUMOylation in Cystic Cholangiocytes Halts Polycystic Liver Disease in Experimental Models
(Elsevier, 2021-02)
BACKGROUND & AIMS: Polycystic liver diseases (PLDs) are genetic disorders characterized by progressive development of multiple fluid-filled biliary cysts. Most PLD-causative genes participate in protein biogenesis and/or ...
Methionine adenosyltransferase 1a antisense oligonucleotides activate the liver-brown adipose tissue axis preventing obesity and associated hepatosteatosis
(Nature, 2022)
Altered methionine metabolism is associated with weight gain in obesity. The methionine adenosyltransferase (MAT), catalyzing the first reaction of the methionine cycle, plays an important role regulating lipid metabolism. ...
Liver osteopontin is required to prevent the progression of age-related nonalcoholic fatty liver disease
(Wiley, 2020-07-07)
[EN] Osteopontin (OPN), a senescence-associated secretory phenotype factor, is increased
in patients with nonalcoholic fatty liver disease (NAFLD). Cellular senescence
has been associated with age-dependent hepatosteatosis. ...
Targeting NAE1-mediated protein hyper-NEDDylation halts cholangiocarcinogenesis and impacts on tumor-stroma crosstalk in experimental models.
(Elsevier, 2022-07)
[EN] BACKGROUND & AIMS: Cholangiocarcinoma (CCA) comprises a heterogeneous group of malignant tumors associated with dismal prognosis. Alterations in post-translational modifications (PTMs), including NEDDylation, result ...
Targeting E2F Sensitizes Prostate Cancer Cells to Drug-Induced Replication Stress by Promoting Unscheduled CDK1 Activity
(MDPI, 2022-10-10)
E2F1/E2F2 expression correlates with malignancy in prostate cancer (PCa), but its functional significance remains unresolved. To define the mechanisms governed by E2F in PCa, we analyzed the contribution of E2F target genes ...
