Ubiquitination in cancer: mechanisms and therapeutic opportunities
Abstract Ubiquitination, a key post‐translational modification, plays an essential role in tumor biology by regulating fundamental cellular processes, such as metabolism and cell death. Additionally, it interacts with other post‐translational modifications, which are closely linked to tumorigenesis, tumor progression, the tumor microenvironment, and ...

Activation of the Retinoid X Receptor Suppresses Appetite in the Rat [PDF]
AbstractThe retinoid X receptor (RXR), a ubiquitously expressed intracellular receptor, regulates pathways controlling glucose, triglycerides, cholesterol, and bile acid metabolism. In addition to its role in those metabolic pathways, we reported that RXR activation with a pan agonist [e.g.

Retinoid regulated macrophage cholesterol efflux involves the steroidogenic acute regulatory protein
Elimination of excess cholesteryl esters from macrophage-derived foam cells is known to be a key process in limiting plaque stability and progression of atherosclerotic lesions.

Abstract Post‐translational modifications (PTMs) play a pivotal role in epigenetic regulation and are key pathways for modulating protein functionality. PTMs involve the covalent attachment of distinct chemical groups, such as succinyl, crotonyl, and lactyl, at specific protein sites, which alter protein structure, function, stability, and activity ...

Pure and functionally homogeneous recombinant retinoid X receptor. [PDF]
Mouse retinoid X receptor alpha (RXR alpha) lacking the amino-terminal region A/B (RXR alpha delta AB) has been purified to more than 98% purity and functional homogeneity from bacterial and baculovirus-based recombinant expression systems with yields of 2-8 mg/liter of culture.

Retinoid X Receptor α-Dependent HBV Minichromosome Remodeling and Viral Replication
Background and aim. The HBV covalently closed circular DNA (cccDNA) is organized into a minichromosome in the nuclei of infected hepatocytes through interactions with histone and nonhistone proteins.

Roles of distinct nuclear receptors in diabetic cardiomyopathy
Diabetes mellitus induces a pathophysiological disorder known as diabetic cardiomyopathy and may eventually cause heart failure. Diabetic cardiomyopathy is manifested with systolic and diastolic contractile dysfunction along with alterations in unique ...

The transcription factor retinoid X receptor-alpha (RXRα) can also form homotetramers. Here the authors show that the anti-cancer agent K-80003 selectively inhibits the nongenomic action of N-terminally-cleaved RXRα in tumour cells by stabilizing its ...

Blue light regenerates functional visual pigments in mammals through a retinyl-phospholipid intermediate. [PDF]
The light absorbing chromophore in opsin visual pigments is the protonated Schiff base of 11-cis-retinaldehyde (11cRAL). Absorption of a photon isomerizes 11cRAL to all-trans-retinaldehyde (atRAL), briefly activating the pigment before it dissociates ...

Abstract Clascoterone is an androgen receptor inhibitor approved for the treatment of acne vulgaris in patients 12 years of age and older. Here, we report results of 5 phase 1 studies that assessed the pharmacokinetics (PK), safety, and skin irritation and sensitization potential of clascoterone cream 1% in healthy participants and patients with acne ...
