生物活性

Vitamin A (Vitamin A1) is an endogenous metabolite.

IC50 & Target

Human Endogenous Metabolite

 

体外研究
(In Vitro)

It is found that contribution of hepatic microsomes (RDHs) to Retinol metabolism is greater than that of cytosol (ADHs), evidenced by higher Clint (Vmax/Km) of Vitamin A formation in microsomes than in cytosol[1].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

体内研究
(In Vivo)

The results show that compare with control (CON) rats, high-fat diet (HFD) significantly lowers basal level of Vitamin Al in plasma, but markedly elevates basal levels of Retinol in kidney, adipose tissue and liver. The results show that Vitamin Al absorption in HFD rats is faster than that in CON rats, evidenced by significantly shorter Tmax (3.0±0.0 h for HFD rats vs 5.8±1.1 h for CON rats, p<0.05)[1]. The plasma Vitamin A levels in methionine-choline deficient diet (MCD) rats are significantly lower than in the controls while the hepatic Vitamin A levels in MCD rats are markedly higher. The hepatic expression of Retinol-metabolizing enzymes and binding proteins (GRBP-I, ALDH1A1, and ALDH1A2) in MCD rats is significantly higher than that in control rats[2].

Kinase Assay
[1]

Activity of alcohol dehydrogenases (ADHs)/retinol dehydrogenases (RDHs) and retinal dehydrogenases (RALDHs) are assessed. Briefly, hepatic ADHs/RDHs and RALDHs activities are evaluated with Retinal formation in the presence of β-nicotinamide adenine dinucleotide (β-NAD+) and β-Nicotinamide adenine dinucleotide phosphate (β-NADP+), respectively. The incubation mixture consists of hepatic cytosol/microsomes (at the final concentration of 0.5 mg/mL), and a series concentrations of Retinol, 4.0 mM co-factor, 5 mM MgCl2, 91 μM butylated hydroxytoluene in a total volume of 500 μL. The reaction is initiated by the addition of Retinol pre-incubated for 5 min at 37°C. Following 15 min incubation, the reaction is quenched by extraction with equal volume of n-butanol/methanol, 95:5 (v:v) containing 0.005% butylated hydroxytoluene[1].

Animal Administration
[2]

Wistar rats (male, aged 4 wk) are used in this study. Two groups of 6 rats are given free access to the following diets: the standard diet (control group) and the methionine-choline deficient diet (MCD) group. Each diet contains Retinol (1000 IU/100g). After 6 wk, the rats are sacrificed by exsanguination under isoflurane anesthesia after an overnight fast. Blood is collected in heparinized tubes, and plasma is separated for storage at -80°C. The liver, intestine, testes, and kidneys are removed, immediately frozen in liquid nitrogen, and stored at -80°C[2].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
