The NADPH oxidase NOX4 regulates redox and metabolic homeostasis preventing HCC progression

open access: yesHepatology, EarlyView., 2022
Loss of NOX4 in HCC tumor cells induces metabolic reprogramming in a Nrf2/MYC‐dependent manner to promote HCC progression. Abstract Background and Aims The NADPH oxidase NOX4 plays a tumor‐suppressor function in HCC. Silencing NOX4 confers higher proliferative and migratory capacity to HCC cells and increases their in vivo tumorigenic potential in ...

RETINENE ISOMERASE [PDF]

open access: yesThe Journal of General Physiology, 1956
Rhodopsin is formed by the condensation of opsin with a cis isomer of retinene, called neo-b. The bleaching of rhodopsin releases all-trans retinene which must be isomerized back to neo-b in order for rhodopsin to regenerate. Both retinene isomers are in equilibrium with the corresponding isomers of vitamin A, through the alcohol dehydrogenase system.

Overcoming the thermodynamic equilibrium of an isomerization reaction through oxidoreductive reactions for biotransformation

open access: yesNature Communications, 2019
A desired product cannot be obtained at higher concentration than its equilibrium concentration when isomerases are used for biotransformation. Here, the authors engineer in vivo oxidoreductive reactions in yeast to overcome the equilibrium limitation of

Dual-Family Peptidylprolyl Isomerases (Immunophilins) of Select Monocellular Organisms

open access: yesBiomolecules, 2018
The dual-family peptidylprolyl cis-trans isomerases (immunophilins) represent a naturally occurring chimera of the classical FK506-binding protein (FKBP) and cyclophilin (CYN), connected by a flexible linker.

Peptidyl-prolyl cis-trans isomerases (immunophilins) and their roles in parasite biochemistry, host-parasite interaction and antiparasitic drug action. [PDF]

open access: yes, 2006
Immunophilin is the collective name given to the cyclophilin and FK506-binding protein (FKBP) families. As the name suggests, these include the major binding proteins of certain immunosuppressive drugs: cyclophilins for the cyclic peptide cyclosporin A ...

Intracellular trafficking, localization, and mobilization of platelet-borne thiol isomerases [PDF]

open access: yes, 2016
OBJECTIVE: Thiol isomerases facilitate protein folding in the endoplasmic reticulum, and several of these enzymes, including protein disulfide isomerase and ERp57, are mobilized to the surface of activated platelets, where they influence platelet ...

The cuticle [PDF]

open access: yes, 2007
The nematode cuticle is an extremely flexible and resilient exoskeleton that permits locomotion via attachment to muscle, confers environmental protection and allows growth by molting.

The importance of arginine codons AGA and AGG for the expression in E. coli of triosephosphate isomerase from seven different species

open access: yesBiotechnology Reports, 2017
Rare arginine codons AGA and AGG affect the heterologous expression of proteins in Eschericha coli. The tRNAs necessary for protein synthesis are scarce in E. coli strain BL21(DE3) pLysS and plentiful in strain BL21(DE3) CodonPlus −RIL.
