Cancers

Ribas V, de la Rosa LC, Robles D, Núñez S, Segalés P, Insausti-Urkia N, Solsona-Vilarrasa E, Fernández-Checa JC, García-Ruiz C.
PMID: 34439245
Cancers (Basel). 2021 Aug 13;13(16). doi: 10.3390/cancers13164091.

The association of nonalcoholic steatohepatitis (NASH) with obesity and type 2 diabetes is a major determinant factor for the continued rise of NASH-driven HCC. Unfortunately, the mechanisms underlying the progression from NASH to HCC are not well-understood. Steatosis is...

MITOCHONDRIAL CHOLESTEROL AND CANCER.

Seminars in cancer biology

Garcia-Ruiz C, Conde de la Rosa L, Ribas V, Fernandez-Checa JC.
PMID: 32805396
Semin Cancer Biol. 2021 Aug;73:76-85. doi: 10.1016/j.semcancer.2020.07.014. Epub 2020 Aug 14.

Cholesterol is a crucial component of membrane bilayers that determines their physical and functional properties. Cells largely satisfy their need for cholesterol through the novo synthesis from acetyl-CoA and this demand is particularly critical for cancer cells to sustain...

Hepatology. 2021 Nov;74(5):2791-2807. doi: 10.1002/hep.32029. Epub 2021 Sep 25.

BACKGROUND AND AIMS: Hepatocellular dedifferentiation is emerging as an important determinant in liver disease progression. Preservation of mature hepatocyte identity relies on a set of key genes, predominantly the transcription factor hepatocyte nuclear factor 4α (HNF4α) but also splicing...

GST-Perfringolysin O production for the localization and quantification of membrane cholesterol in human and mouse brain and liver.

STAR protocols

Goicoechea L, Arenas F, Castro F, Nuñez S, Torres S, Garcia-Ruiz C, Fernandez-Checa JC.
PMID: 35024626
STAR Protoc. 2021 Dec 29;3(1):101068. doi: 10.1016/j.xpro.2021.101068. eCollection 2022 Mar 18.

Abnormal cholesterol metabolism is linked to many neurodegenerative disorders. Here, we present a protocol for the production of a recombinant protein consisting of a Glutathione-S-Transferase tag fused with the Perfringolysin O (PFO). The GST-PFO tag enables analysis of the...

STARD1 promotes NASH-driven HCC by sustaining the generation of bile acids through the alternative mitochondrial pathway.

Journal of hepatology

Conde de la Rosa L, Garcia-Ruiz C, Vallejo C, Baulies A, Nuñez S, Monte MJ, Marin JJG, Baila-Rueda L, Cenarro A, Civeira F, Fuster J, Garcia-Valdecasas JC, Ferrer J, Karin M, Ribas V, Fernandez-Checa JC.

BACKGROUND & AIMS: Besides their physiological role in bile formation and fat digestion, bile acids (BAs) synthesised from cholesterol in hepatocytes act as signalling molecules that modulate hepatocellular carcinoma (HCC). Trafficking of cholesterol to mitochondria through steroidogenic acute regulatory...

Acetaminophen (APAP) toxicity is the most common cause of acute liver failure and a major indication for liver transplantion in the United States and Europe. Although significant progress has been made in understanding the molecular mechanisms underlying APAP hepatotoxicity,...
