    Hemin purchased from MedChemExpress. Usage Cited in: Genome Biol. 2022 Dec 15;23(1):259.  [Abstract]

    Hemin (0, 20, 40, 80 µM; 2 h) increases G4 levels in a dose-dependent manner in HeLa cells. Immunostaining of G4 using BG4-EGFP (green). The nuclei are stained with DAPI (blue).

    Description

    Hemin is an iron-containing porphyrin. Hemin is an Heme oxygenase (HO)-1 inducer.

    IC50 & Target

    Heme oxygenase[1]

    In Vitro

    Hemin and PGJ2, used as positive controls, strongly increase both expression and activity of HMOX after 4 and 12 h, respectively. Indeed, a significant effect is found of 30 μM Hemin on cell proliferation in all used cell lines after 48 h, which is dose-dependent. Hemin treatment decreases cell proliferation to 62±5 %, 51±3 %, and 38±8 % in PA-TU-8902, BxPC-3 and MiaPaCa-2 cancer cells, respectively, with p<0.0001 for all comparisons. Furthermore, enhancement of anti-proliferative effects of statins is observed by Hemin, documented as decreased cell proliferation after 48 h of co-treatment[1].

    In Vivo

    Following the i.p. administration of Hemin (100 μmol/kg), the HO-1 level in the renal cortex begins to increase gradually. The HO-1 level reaches its peak 24 h after Hemin preconditioning. HO-1 is expressed mainly in the renal tubules. The HO-2 level in the kidney does not change following Hemin preconditioning[2].

    Cell Assay
    [1]

    For the cell proliferation assay, cells are seeded into 96 well (5-12.5×104 cells per mL according to the cell line) and kept at 37°C and 5 % CO2. After 24 h, cells are treated with statins or/and Hemin, followed by the MTT test as a general cell proliferation assay[1].

    Animal Administration
    [2]

    Mice[2]
    Eight- to ten-week-old male BABL/c mice are used for the ischemia-reperfusion (I/R) experiments. The animals are divided into five groups as follows: (1) the sham group undergo isolation of the bilateral renal arteries without clamping; (2) the vehicle group receive an intraperitoneal (i.p.) injection of 4 mL/kg PBS as a vehicle control (with IRI); (3) the Hemin-preconditioned group receive Hemin, a potent inducer of HO-1, at 100 μmol/kg i.p.; (4) the Hemin plus ZnPP group receive zinc protoporphyrin IX, an inhibitor of HO-1 activity, at 5 mg/kg i.p. 6 h after receiving 100 μmol/kg Hemin i.p.; and (5) the Hemin plus PD98059 group receive PD98059, an inhibitor of ERK1/2 activity, at 10 mg/kg i.p. 6 h after receiving 100 μmol/kg Hemin i.p. Both inhibitors are administered i.p. 2 h before I/R, whereas Hemin was administered 8 h before I/R.

    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.
