Biotin is a bi-heterocyclic, essential water soluble vitamin and a cofactor synthesized in most of the plants and prokaryotes. Protein-bound biotin in usually found in dietary sources like meat, cereals, egg yolk, liver and some vegetables.

Biochem/physiol Actions
Biotin functions as a coenzyme for acetyl CoA, pyruvate, propionyl-CoA and 3-methylcrotonyl-CoA carboxylases for the regulation of gluconeogenesis, lipid homeostasis, pleotropic gene expression and to replenish the intermediates of tricarboxylic cycle. Biotin bound to histones plays an important role in chromatin remodeling, DNA repair and repression of transposons to maintain genome stability. Inadequate biotin levels may lead to dermatitis, conjunctivitis, alopecia, and central nervous system abnormalities.

Nitric oxide (NO) is produced by different isoforms of nitric oxide synthases (NOSs) and operates as a mediator of important cell signaling pathways, such as the cGMP signaling cascade. Another mechanism by which NO exerts biological effects is mediated through

Healing large bone defects and non-unions remains a significant clinical problem. Current treatments, consisting of auto and allografts, are limited by donor supply and morbidity, insufficient bioactivity and risk of infection. Biotherapeutics, including cells, genes and proteins, represent promising alternative
Ubiquitination is a key post-translational modification in the regulation of numerous biological processes in eukaryotes. The primary roles of ubiquitination are thought to be the triggering of protein degradation and the regulation of signal transduction. During protein ubiquitination, substrate specificity
