Increased Brown Adipose Tissue Thermogenesis in Phenylketonuria

open access: yesMedComm, Volume 7, Issue 6, June 2026.
In phenylketonuria (PKU), elevated phenylalanine (Phe) increases hepatic fibroblast growth factor 21 (FGF21) and thyroid hormones, enhancing brown adipose tissue (BAT) thermogenesis in patients. Central FGF21 reproduces this phenotype in rodents via reduced hypothalamic AMP‐activated protein kinase (AMPK) activity in the ventromedial nucleus of the ...

The plasma level of 7α-hydroxy-4-cholesten-3-one reflects the activity of hepatic cholesterol 7α-hydroxylase in man

open access: yes, 1991
Circulating levels of 7α-hydroxy-4-cholesten-3-one have been compared with activities of the rate-limiting enzyme in bile acid synthesis, microsomal cholesterol 7α-hydroxylase, measured in liver biopsies obtained from patients undergoing surgery for ...

From HBV to MASLD Cirrhosis: Mechanistic Insights and Therapeutic Strategies

open access: yesPortal Hypertension &Cirrhosis, Volume 5, Issue 2, Page 170-188, June 2026.
This review examines the epidemiological shift from hepatitis B virus (HBV) to metabolic dysfunction‐associated steatotic liver disease (MASLD) as the leading cause of cirrhosis globally. It highlights the distinct pathogenic mechanisms between HBV and MASLD cirrhosis and discusses evolving diagnostic tools and therapeutic strategies tailored to the ...

The acidic pathway of bile acid synthesis: Not just an alternative pathway

open access: yesLiver Research, 2019
Over the last two decades, the prevalence of obesity, and metabolic syndromes (MS) such as non-alcoholic fatty liver disease (NAFLD) and type 2 diabetes mellitus (T2DM), have dramatically increased.

Oxygen‐independent expression of HIF‐1α during the cell cycle in hepatocellular carcinoma cells controls essential metabolic pathways under normoxia

open access: yesThe FEBS Journal, Volume 293, Issue 11, Page 3140-3165, June 2026.
Intra‐tumoral oxygen deprivation (hypoxia) promotes the activation of hypoxia‐inducible factors (HIFs) that orchestrate the transcriptional adaptation of cancer cells to hypoxia. Hypoxia is prevalent in hepatocellular carcinoma (HCC), a cancer type with limited therapeutic options.

Effect of pregnancy and lactation on lipoprotein and cholesterol metabolism in the rat

open access: yesJournal of Lipid Research, 1998
Origins of hyperlipidemia and cholestasis that occur during pregnancy were investigated by examining expression of key elements related to plasma and hepatic cholesterol metabolism during pregnancy, lactation, and post-lactation in the rat model.

Macrophage inhibitory cytokine-1 aggravates diet-induced gallstone formation via increased ABCG5/ABCG8 expression.

open access: yesPLoS ONE, 2023
Macrophage inhibitory cytokine 1 (MIC-1), which is overproduced in various human cancers and associated with cachexia, acts on the hypothalamus to suppress appetite and reduce body weight.

Delayed diagnosis of 3β‐HSD7 deficiency in adolescence: Two case reports and review of the literature

open access: yesJPGN Reports, Volume 7, Issue 2, Page 236-241, May 2026.
Abstract Congenital bile acid synthesis defects (BASD), the most common of which is 3β‐hydroxy‐Δ5‐C27‐steroid dehydrogenase oxidoreductase (3β‐HSD7) deficiency, are a rare cause of fat‐soluble vitamin malabsorption. We describe a 14‐year‐old girl who presented at 14 months with a left distal femur fracture and failure to thrive.

Multiplicity of 3-Ketosteroid-9α-Hydroxylase Enzymes in Rhodococcus rhodochrous DSM43269 for Specific Degradation of Different Classes of Steroids [PDF]

open access: yes, 2011
The well-known large catabolic potential of rhodococci is greatly facilitated by an impressive gene multiplicity. This study reports on the multiplicity of kshA, encoding the oxygenase component of 3-ketosteroid 9α-hydroxylase, a key enzyme in steroid ...
