[21] When treated with cyanocobalamin, patients with Leber's disease may develop serious optic atrophy, possibly leading to blindness, based on few case reports
This reaction serves as the primary and often rate-limiting entry point into the aliphatic glucosinolate system ( 2.1.2 MAM1: The commitment step in chain elongation Following initial transamination, Methylthioalkylmalate Synthase 1 (MAM1) catalyzes the first condensation reaction, representing the committing step in side-chain elongation ( 2.1.3 CYP79F1: The aldoxime-forming branch point The pathway converges on Cytochrome P450 Monooxygenase CYP79F1, a critical branch point enzyme that catalyzes the conversion of chain-elongated methionine derivatives (ranging from mono-to hexahomomethionine) to their corresponding aldoximes through N-hydroxylation reactions, representing a critical branch point in aliphatic glucosinolate biosynthesis ( 2.2 Transcriptional and epigenetic regulation: a multi-layered control system The precise spatial and temporal accumulation of glucoraphanin is dynamically controlled by a sophisticated regulatory regime that integrates transcriptional, epigenetic, and post-translational cues ( Figure 3 )
It resets gene expression to a "younger/healthier" state suppressing inflammatory and metastatic genes while activating repair and remodeling genes
38,39 However, defining its primary source during neonatal hypoxia-ischemia via peripheral blood sampling remains challenging
