Acitretin does not induce HIV reactivation in J-lat and ACH-2 cells. (a, b) HIV reactivation induced by acid retinoic (AR) derivative acitretin (25 – 1 μM) in J-Lat cells clone 8.4 (a) and 9.2(b). HDAC inhibitors (HDCAi) panobinostat (PNB, 0.16μM) and vorinostat (VOR, 4 – 0.16 μM) were used as controls. Reactivation was determined by the quantification of GFP+ cells (%) after culturing J-Lat with HDACi and acitretin for 24h. (c, d) HIV reactivation induced by acitretin and HDACi in ACH-2 cells. Reactivation was determined after 48h of incubation by quantification of CAp24 (c) and HIV RNA copy number (d) in the supernatant. Values represent mean±SD of at least three independent experiments performed in triplicate. UN, untreated. *P < 0.05; **P < 0.01; ***P < 0.001.

|Description||Acitretin is a second generation retinoid used for psoriasis.|
Acitretin stimulates ADAM10 promoter activity with an EC(50) of 1.5 mM and leads to an increase of mature ADAM10 protein that results in a two- to three-fold increase of the ratio between alpha- and beta-secretase activity in neuroblastoma cells.  Acitretin (5-20 μM) impairs mitochondrial phosphorylation efficiency as demonstrated by the decrease in the state 3 respiration and ATP levels, and by the increase in the lag phase of ADP phosphorylation cycle, without affecting the membrane potential. Acitretin induces Ca(2+)-mediated mitochondrial permeability transition (MPT) and decreased the adenine nucleotide translocase (ANT) content.  Acitretin preferentially inhibits the growth of SCL-1 cells in a dose- and time-dependent manner, but not of non-malignant keratinocyte HaCaT cells. Acitretin increases the levels of CD95 (Fas), CD95-ligand and Fas-associated death domain. Acitretin is able to induce apoptosis in skin cancer cells possibly via death receptor CD95 apoptosis pathway without affecting the viability of normal keratinocyte. 
|In vivo||Acitretin undergoes alpha-oxidation, chain shortening O-demethylation, and glucuronidation in the perfused rat liver.  Acitretin rapidly appears in liver and muscle of rats, where it undergoes redistribution into skin and adipose tissue. |

Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (g) = Concentration (mol/L) × Volume (L) × Molecular Weight (g/mol)
*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).
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 )
* 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.
