Description

Vitamin D3 (Cholecalciferol; Colecalciferol) is a naturally occuring form of vitamin D. Vitamin D3 induces cell differentiation and prevents proliferation of cancer cells.

IC50 & Target

Human Endogenous Metabolite

 

In Vitro

Vitamin D3 is an inactive vitamin D molecule in vivo. Vitamin D3 undergoes two hydroxylation processes to activate it. Vitamin D3 is first hydroxylated in the liver to form the circulating prohormone 25-hydroxy vitamin D3 [25(OH)D3] by the enzyme 25-hydroxylase (CYP27A1) and probably also by other enzymes (e.g., CYP2R1)[1].
The second hydroxylation occurs in the kidneys via the enzyme 1-alpha-hydroxylase, yielding 1,25- dihydroxycholecalciferol (calcitriol), which is the biologically active form of vitamin D[1].
Vitamin D3 (2-10 μM; 24-48 hours) exhibits anti-proliferative effects in a dose- and time-dependent manner. Maximal reduction of viability post-treatment of 62% (IK), 52% (RL-95-2), and 55% (Hec-1A) occurs by 72 h of treatment with 10 μM Vitamin D3. but 24-hour exposure lacks significant reduction in viable cells[2].
Cholecalciferol (10 μM; 24-48 hours) shows marked increases in nuclear VDR staining and produces local VDR activation in IK cells[1].

Cell Viability Assay[2]

Cell Line: EC cell lines from EEC, Ishikawa 3-H-12(IK), RL-95/2, and HEC-1-A cells
Concentration: 2-10 μM
Incubation Time: 24-72 hours
Result: Reduced viability in response to VD3 in a dose- and time-dependent manner.
Indicated that the conversion of VD3 to 25(OH)D is an essential step for the reduced cell viability effect.

Cell Viability Assay[2]

Cell Line: EC cell lines from EEC, Ishikawa 3-H-12(IK) cells
Concentration: 10 μM
Incubation Time: 24-48 hours
Result: Improved nuclear VDR content in IK cells.
In Vivo

Cholecalciferol (oral gavage; 5 mg/kg; 7 days) potentiates the CCl4 toxicity only in the liver, as indicated by plasma levels of ALT and AST, biochemical markers of hepatic damage. It significantly increases renal calcium levels in mice, but renal calcium content does not differ significantly between mice[3].

Animal Model: Male ddY mice on CCl4 toxicity[3]
Dosage: 5 mg/kg
Administration: Oral gavage; 5 mg/kg; 7 days
Result: Potentiated CCl4-induced hepatotoxicity and enhanced mouse mortality, without increasing renal toxicity and generation of liver fibrosis.

In Vivo:

Select the appropriate dissolution method based on your experimental animal and administration route.

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

  • Protocol 1

    Add each solvent one by one:  10% DMSO    90% (20% SBE-β-CD in Saline)

    Solubility: 2.08 mg/mL (5.41 mM); Suspended solution; Need ultrasonic

    This protocol yields a suspended solution of 2.08 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.

    Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.
  • Protocol 2

    Add each solvent one by one:  10% DMSO    40% PEG300    5% Tween-80    45% Saline

    Solubility: ≥ 1 mg/mL (2.60 mM); Clear solution

    This protocol yields a clear solution of ≥ 1 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (10.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.

    Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.

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.
