ALAS and PLP Evolution of these regions may have played a role in alterations of PLP binding and its regulation for ALAS to play specific roles in adaptation of heme synthesis to cell-specific contexts. As PLP is generally maintained at a low concentration in the cell (Hamfelt, 1967; Cheung et al., 2003), and its spontaneous conjugation to apoALAS is slow (Kardon et al. 2015), it is likely that vertebrate ALAS requires other, yet to be discovered chaperones that facilitate PLP incorporation to form the holoenzyme.

Reverse activity of FECH is triggered by fatty acids Previous studies (1,5,21) have found that FECH activity increases owing to various lipids including fatty acids and phospholipids. To determine the effects of fatty acids on iron-removal reverse activity, we added sodium palmitate to the reaction mixture. Upon increasing the concentration of sodium palmitate to 100 mg/ml, the forward and reverse activities increased concentration dependently, and the rates of the forward and reverse reactions increased 2.

High NAD/NADH ratio in cytoplasm, low in mitochondria In rat liver it was found that NAD/NADH ratio differs significantly between cytoplasm and mitochondria: The mean NAD+/NADH ratio of rat-liver cytoplasm was calculated as 725 (pH7·0) in well-fed rats, 528 in starved rats and 208 in alloxan-diabetic rats. The NAD+/NADH ratio for the mitochondrial matrix and cristae gave virtually identical values in the same metabolic state. This indicates that β-hydroxybutyrate dehydrogenase and glutamate dehydrogenase share a common pool of dinucleotide.

Sulfite protects neurons from oxidative stress Our present data have shown sulfite to be a novel cytoprotective molecule against oxytosis, through maintaining cysteine levels in the extracellular milieu, leading to increased intracellular cysteine and GSH. Although there may be adverse clinical effects in sensitive individuals, our results provide a new insight into the therapeutic application of sulfite to neuronal diseases caused by oxidative stress. Free sulfite, present at approximately 2 μM in the rat brain, converts cystine to cysteine more efficiently than H2S and H2Sn and facilitates transport of cysteine into cells.

Pyruvate Dehydrogenase Complex Pyruvate Dehydrogenase Complex generates significant amount of reactive oxygen when supply of NAD+ is not sufficient and when the ratio dihydrolipoate/lipoate is increased: Experiments conducted using isolated enzyme have demonstrated PDC-stimulated rates of O2•− to be maximal under conditions in which the steady-state ratio of dihydrolipoate to lipoate within E2 is shifted in favor of the reduced form and supply of NAD+ is decreased (i.e., ↑dihydrolipoate/lipoate, ↑NADH/NAD+).

Benfotiamine Metabolism of Benfotiamine appears to depend on GSH in erythrocytes: Their results suggested that benfotiamine (given orally) is first dephosphorylated to S-benzoylthiamine by the ecto-alkaline phosphatase present in the brush borders of intestinal mucosal cells. The more lipophilic S-benzoylthiamine then diffuses through the membranes of intestinal and endothelial cells and appears in the venous mesenteric blood. A significant part of S-benzoylthiamine is captured by erythrocytes and converted to free thiamine through a slow non-enzymatic transfer of the S-benzoyl group to SH groups of glutathione.

Transcription factors From the section “CHEA Transcription Factor Targets” (R1): Transcription factor Notes CEBPB Important transcription factor regulating the expression of genes involved in immune and inflammatory responses. Plays a significant role in adipogenesis, as well as in the gluconeogenic pathway, liver regeneration, and hematopoiesis. CRX CRX gene can directly regulate the expression of the TCN2 gene in cells of the retina.

Quotes from the Interview (R1) 4. What are the qualities of OSR? Could you explain them, please? SAFETY: OSR is made from coupling two natural compounds that are not toxic alone and used as antioxidants. Even the FDA agrees that OSR (as emeramide) is very safe for human ingestion. We have exposed test animals to osr at over 1,000 mg/kg body weight without inducing any toxic effects. We have used emeramide (OSR) in at least 5 human phase I and phase II studies without inducing any significant drug related adverse effects.

Role in Health TBD Types of inositol TBD Phytic acid TBD Synthesis TBD: description and illustration Genes TBD Regulation TODO: Gsk3b activates synthesis Inositol inhibits autophagy On the other hand, lithium induced autophagy independently of mTOR through the inhibition of inositol monophosphatase (IMPase). IMPase catalyzes the hydrolysis of inositol monophosphate (IP1) into free inositol required for the phosphoinositol signaling pathway. Lithium affects this pathway by inhibiting IMPase, leading to free inositol depletion, which in turn decreases myo-inositol-1,4,5-trisphosphate (IP3) levels (Figure 2).
