Biological Activity

Description Doxycycline is an antibiotic that is used in the treatment of a number of types of infections caused by bacteria and protozoa.
In vitro

100 ng/mL-5 µg/mL Dox can significantly alter the metabolic profile of the cell, as well as reduce the proliferative rate, though the effect size depends upon the particular cell line used[1]. Doxycycline arrests cells in G1-S phase of the cell cycle in PANC-1 cells and induces the expression of p53 and its downstream target p21. It down-regulates antiapoptotic genes and induces proapoptotic genes. Doxycycline also induces apoptosis through a Fas/Fas-ligand dependent pathway in Jurkat T lymphocytes[2].

Western blot
AKT / BCL6 / Cyclin E / HDAC2 / HDAC3 / NEMO / TYK2 / RIPK1 ; 

PubMed: 26142707     

Doxycycline treatment decreases the levels of HSP90 client proteins in DLBCL cells. The DLBCL cells were treated with the indicated concentrations of doxycycline for 24 hrs. The levels of HSP90 client proteins in these cells were analyzed by western blotting.

HSP70 / HSP90 ; 

PubMed: 26142707     

Reduced protein levels of HSP70 and HSP90 in DLBCL cells treated with doxycycline. DLBCL cells were treated with doxycycline for 24 hrs, and the levels of HSP70 and HSP90 were analyzed by western blotting. 

pATM / ATM ; 

PubMed: 23282955     

Levels of phosphorylated ATM and overall ATM was determined in the indicated cell lines at the indicated times after treatment with 1μg/ml doxycycline, as detected by Western Blotting.

26142707 23282955
E-cadherin / Vimentin ; 

PubMed: 29285218     

Doxycycline increases E-cadherin expression and decreases Vimentin expression, whereas thrombin partly counteracts this inhibitory effect in MCF-7 cells.

In vivo Doxycycline successfully reduces tumor growth in vivo (inhibited pancreatic cancer cell growth)[2].


Cell Research:

  • Cell lines: U87 astrocytoma cells, lung cancer cell lines H157 and H1437, LNCaP prostate cancer and HeLa cervical cancer cell lines
  • Concentrations: 100 ng/mL, 1 µg/mL
  • Incubation Time: 24, 72, and 96 hours
  • Method:

    Cells are seeded in 6 well plates at 50,000 cells per well and treated with Dox (100 ng/mL, 1 µg/mL, or vehicle control). Cells are counted 24, 72, and 96 hours after plating using a particle counter.

Bio Calculators

Molarity Calculator

Molarity Calculator

Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:

Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)

  • Mass
    Molecular Weight

*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).

Dilution Calculator

Dilution Calculator

Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:

Concentration (start) x Volume (start) = Concentration (final) x Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )

  • C1

* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:

Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
