Definitions
- the subject of the present invention is the use of an enzyme with dehydrogenase-reductase activity as a research tool in the disorders associated with hyperseborrhoea, in particular acne.
- the subject of the invention is also the use of this enzyme for the identification of a compound intended for the treatment of acne, seborrheic dermatitis and / or skin disorders associated with hyperseborrhoea, as well as a method for treating identification of such a compound.
- Acne is a multifactorial disease characterized by abnormal production of sebum and ductal coming, followed by bacterial colonization and inflammation.
- Today, the most effective product to treat this pathology is a synthetic retinoid, 13-cis retinoic acid or isotretinoin (Roaccutane TM). This product, however, has severe side effects, including teratogenicity.
- 13-cis retinoic acid is effective against oral acne ("Diagnosis and Treatment of Acne", Feldman et al., Am Fam Physician, 2004 May 1; 69 (9): 2123-30), its mechanism of action is still unknown.
- the main advantage of 13-cis retinoic acid is its ability to significantly decrease sebum production ("Effect of oral 13-cis retinoic acid at three dose levels on sustainable secretions of sebum secretion and on acne", Stewart ME and al, J Am Acad Dermatol, 1983 Apr; 8 (4): 532-8 and "Isotretinoin - an explanation for the long-term benefit", Cunliffe WJ et al, Dermatologica, 1987; 175 Suppl 1: 133-7).
- 13-cis retinoic acid is much more effective orally than other natural or synthetic retinoids (Cunliffe WJ, Norris JF "Isotretinoin-an explanation for long-term benefit", Dermatologica, 1987; 175 Suppl 1: 133-7).
- Original pharmacokinetic properties have been proposed to explain this efficacy.
- RAR Retinoic Acid Receptors
- a metabolite derived from dihydroxytestosterone, 3 ⁇ -androstanediol glucuronide Effect of oral isotretinoin treatment on skin androgen receptor levels in acneic patients", Boudou P et al, J Clin Endocrinol Metab, 1995 Apr; 80 (4): 1158-61 and "Isotretinoin, tetracycline and circulating hormones in acne, Palatsi R et al., Acta Derm Venerol, 1997 Sep; 77 (5): 394-6).
- Roaccutane may act by altering the intracellular androgenic concentration through the inhibition of enzymes involved in the most effective androgen catabolism, DHT (Expression cloning and characterization of oxidative 17beta and 3alpha- hydroxysteroid dehydrogenases from rat and human prostate ", Biswas MG et al., J Biol Chem, 1997 Jun 20; 272 (25): 15959-66 and” Cloning of the human RoDH-related short chain dehydrogenase gene and analysis of structure " , Kedishvili NY et al., Chem Biol Interact, 2001 Jan 30; 130-132 (1-3): 457-67).
- RoDHs have been identified in humans. These enzymes are cytosolic or microsomal, work with NAD or NADP as a cofactor, and are sensitive to different retinoids. Their mechanism of action is multifunctional, since they may have some activity retinol dehydrogenase, but also 3 ⁇ -hydroxy or 17 ⁇ -hydroxy steroid dehydrogenase.
- these enzymes include RODH or HSE (RoDH-like 3 ⁇ -HSD or 3-hydroxysteroid epimerase) ("Expression cloning and characterization of oxidative 17beta and 3alpha-hydroxysteroid dehydrogenases from rat and human prostate", Biswas MG and al, J Biol Chem, 1997 Jun 20; 272 (25): 15959-66 and "Cloning of the human RoDH-related short chain dehydrogenase gene and analysis of structure", Kedishvili NY et al., Chem Biol Interact, Jan 2001 130-132 (1-3): 457-67), RoDH-4 or Microsomal NAD + -dependent retinol dehydrogenase 4 ("cDNA cloning and characterization of a new human microsomal NAD + - dependent dehydrogenase that oxidizes all-trans-retinol and 3alpha-hydroxysteroids ", Gough WH et al, J Biol Chem, 1998 Ju 31, 273
- DHRS9 called RODH16 in mice
- RAR receptors (o ⁇ ) and ALDH1 RAR receptors (o ⁇ ) and ALDH1
- o ⁇ RAR receptors
- ALDH1 ALDH1
- It is present mainly in the anagenic phases of the hair cycle.
- RoDH-4 and DHRS9 are the only enzymes identified in humans that play a role in the formation of DHT and androstanedione.
- RODH4 has been described in the publication of T. Karlsson et al. (Biochem Biophys Res., 2003 Mar 28; 303 (1): 273-278), as an enzyme involved in the stimulation of sebum secretion in vitro by the transformation of 3-alphadihydrotestosterone and androsterone to dihydrotestosterone (DHT) and androstanedione.
- DHT dihydrotestosterone
- 13-cis retinoic acid (isotretinoin) well known for its anti-acne activity, is believed to reduce the formation of DHT and androstandione in vitro by inhibition of the RODH4 enzyme.
- RoDH4 is not expressed (mRNA) in the human sebaceous glands and weakly in the epidermis. This low presence of mRNA is confirmed using conventional RT-PCR on human epidermal biopsies. The other two subtypes RODH and RODH5 are undetectable in these two compartments of the skin.
- RDH11 is highly expressed in many different tissues with a greater proportion in the spinal cord, prostate, fetal brain, liver, kidney and testis. Unlike RDH11, DHRS9 is found in a much smaller number of organs (testis, heart, marrow and colon) with strong expression in the trachea.
- DHRS9 Hydrogenase Reductase Member 9
- DHRS9 Hydrogenase Reductase Member 9
- This observation is interesting insofar as it allows precisely to consider the activation or selective inactivation of this enzyme in the sebaceous glands unlike other subtypes of RoDH (including RODH4) expressed in humans. It therefore proposes to target the DHRS9 protein to prevent and / or treat acne, seborrheic dermatitis or any other skin disorder associated with hyperseborrhoea.
- Acne means all forms of acne, namely acne vulgaris, comedones, polymorphs, nodulocystic acnes, conglobata, or secondary acne such as solar acne, drug or professional.
- skin disorder associated with a hyperseborrhoea is meant in particular the appearance of oily and / or shiny skin, the presence of comedones, seborrheic dermatitis, the formation of dandruff.
- DHRS9 is expressed in different compartments of human skin tissue, but significantly more in the sebaceous glands than in the epidermis. Except otherwise, “DHRS9” refers to human DHRS9, the sequence of which is referenced in Genbank (NCBI) under accession number NM_005771.
- DHRS9 has no activity with respect to retinoids, but is regulated by them ("Characterization of a novel airway epithelial cell-specific short chain alcohol dehydrogenase / reductase gene whose expression is up- The pharmacokinetics of retinoids are described in Soref CM et al., J Biol Chem, 2001 Jun 29, 276 (26): 24194-202).
- DHRS9 inhibitor means any substance, simple or complex compound, of natural or synthetic origin, capable of inhibiting or reducing the activity or the expression of the DHRS9 enzyme. expression of its gene or the activity of at least one of its promoters, and / or capable of inhibiting, reducing or slowing down the reaction catalyzed by this enzyme. The inhibitor substantially eliminates or reduces the enzymatic activity of DHRS9.
- substantially means a reduction of at least 25%, preferably at least 35%, more preferably at least 50%, and more preferably at least 70% or 90%. More particularly, it may be a compound that interacts with, and blocks, the catalytic site of the enzyme, as compounds of the competitive inhibitory type.
- DHRS9 inhibitors examples include Citral or Carbenoxolone.
- Citral or lemonal is the name given to two isomers of the empirical formula C10H16O.
- the two components are diastereoisomers: the trans isomer is known as geranial or citral A.
- the cis isomer is known as the mineral or citral B.
- Géranial Néral Citral is the major constituent of lemongrass oil and other plants of the genus Cymbopogon. It is also present in verbena, orange or lemon oils.

- the DHRS- 9 is very poorly expressed in other tissues other than the skin, which is an important advantage, which allows avoid known systemic side effects related to changes in androgen metabolism. This weak expression is to oppose to another possible target: RoDH11 which is strongly expressed in many organs and which is ubiquitous.
- FIG. 3 represents a global diagram of the pathogenesis of the disease. acne, which includes the action of DHRS9.
- FIG. 4 represents the activity of conversion of 3 ⁇ -diol to DHT by DHRS9 in cells transfected or not by DHRS9.
- DHRS9 is a potential therapeutic target for the development of new therapies aimed at treating acne, seborrheic dermatitis or any skin disorder associated with hyperseborrhoea.
- the measurement was performed by real-time PCR.
- the expression of the target genes: hRoDH, RoDH11, RoDH-4, RoDH-5 and DHRS9 was conducted on different human tissues using 5 specific primers,
- DHRS9 is predominantly expressed in the colon, spinal cord and trachea.
- This experiment was performed from samples from two different patients. Dissections under binocular microscope and or by laser microdissection on Frozen tissue section was performed to isolate the epidermis and sebaceous glands. The amount of mRNA encoding different enzymes, including DHRS9, was then measured in each of these compartments.
- DHRS9 is expressed at least 20-fold more in the sebaceous glands than in the epidermis alone.
- the cDNA encoding human DHRS9 was subcloned into a pcDNA3.1 / zeo expression vector. This is then transfected into a cell line named PALM for PC-3 Androgen receptor Luciferase MMTV.
- This cell line is derived from PC-3 cells that have been stably transfected with the expression vector encoding the human androgen receptor (pSG5-puro-h androgen receptor (AR)) and the reporter gene vector. coding luciferase (pMMTV-neo-Luc) whose promoter has AR response elements.
- the conversion activity of 3 ⁇ -diol into DHT by the DHRS9 can thus be followed via the AR transactivation.
- the response dose of the 3 ⁇ -diol substrate gives an AC 50 for AR equal to 189nM for untransfected cells compared to 19 nM for cells transfected with DHRS9 (see Figure 4, 0 Transfected cells DHRS9, + Non-transfected cells).
- DHRS9 is able to shift I ⁇ C50 from the 3 ⁇ -Diol to the left by about a log of magnitude thus allowing the evaluation of inhibitors (see Figure 4, 0 Transfected cells DHRS9 , + Untransfected cells).
