Five candidate FR genes, including integral membrane protein 2B (ITM2B), lysophosphatidic acid receptor 6 (LPAR6), motilin receptor (MLNR), calcium-binding protein 39-like (CAB39L), and ADP ribosylation factor-like GTPase 11 (ARL11), were identified as potential initiating drivers of bladder carcinogenesis.
Once converted intracellularly to NAD(P)+, it is used as a co-substrate in two types of intracellular modifications, which control numerous essential signalling events (adenosine diphosphate ribosylation and deacetylation), and is a cofactor for over 400 redox enzymes, thus controlling metabolism.
Indeed, while acetylation and methylation are the most studied phenomena, histones are also submitted to phosphorylation, sumoylation, ubiquitination, and ribosylation. These modifications appear in specific amino acids: acetylation on lysines (K), methylation on lysines and arginines (R), phosphorylation on serines (S) and threonines (T), ubiquitylation, and sumoylation and ribosylation on lysines (29).
The genes encoding SEUSS (SEU) and LEUNIG (LUG) involved in petal polarity determination along the adaxial/ abaxial axis [64], AP2-like transcription factor AINTEGUMENTA (ANT) which contributes to organ polarity [65], the ADP ribosylation factor guanine nucleotide exchange factor GNOM essential for basal polarity establishment in A.
More recently, other posttranslational modifications of histones have been described such as neddylation, sumoylation, glycosylation, phosphorylation, poly-ADP ribosylation, and ubiquitination [2].
These modifications include acetylation, methylation, ubiquitination, propionylation and crotonylation of lysine residues; methylation, ribosylation and citrullination of arginine residues; and the phosphorylation and glycosylation of serines and threonines [55].
In fact, nitration, ribosylation, and other posttranslational modifications of retinal proteins have been shown to occur in diabetes [123].
The histone modifications, including acetylation, methylation, phosphorylation, ADP ribosylation, and ubiquitylation, are different types of histone modifications.
The increase in GAPD (glyceraldehyde 3 phosphate dehydrogenase) can contribute to its ADP ribosylation and nuclear cell death.
Poly(ADP) ribosylation has been also involved in Th2-mediated diseases.
