Definitions
- the present invention relates to nucleic acids expressed from genes located in the human genome in region 9q31-34 of chromosome 9, which may be involved in diseases genetically linked to this chromosomal locus, in particular affections of the metabolism of plasma lipoproteins. , especially the reverse transport of cholesterol.
- the invention also relates to polypeptides encoded by some of these nucleic acids as well as antibodies directed specifically against such polypeptides, useful as diagnostic reagents.
- the invention relates to vectors and recombinant host cells comprising these nucleic acids or fragments thereof.
- Lipoproteins, protein complexes incorporating lipids allowing the transport of these in the blood circulation, normally present in the blood plasma vary in size and composition but all appear in the form of microemulsion.
- the lipoprotein particles are spherical and contain a central core of non-polar lipids (mainly triglycerides and cholesterol esters) and a surface monolayer of polar lipids (cholesterol and mainly phospholipids) and proteins called apolipoproteins (apo) .
- apolipoproteins have amphipathic properties.
- the association of polar lipids and proteins with lipoproteins is thus carried out via hydrophobic forces thanks to which the fatty acid chains and the side chains of non-polar amino acids are excluded from the aqueous environment.
- Most apolipoproteins have helical amphipatic regions (apolipoprotein A1, A-II, A-IV, Cl, C-ll, 0-111 and E).
- the density of the lipoprotein particles is inversely proportional to their size, their density reflecting the relative amounts of low density non-polar lipids contained in the nucleus and high density surface proteins present.
- chylomicrons secreted by enterocytes, in which apo B-48 is predominant
- VLDL secreted by hepatocytes, which contain the protein apo B-100.
- LDL and HDL The smallest classes of lipoproteins, LDL and HDL, mainly contain cholesterol esters in their nucleus.
- the mature forms of these particles are not secreted directly from the cells but are more particularly produced by metabolic pathways within the blood plasma.
- LDL particles represent the end products of VLDL particle metabolism.
- HDL particles Some components of HDL particles are derived from chylomicrons.
- High density lipoproteins are one of the four major classes of lipoproteins that circulate in the blood plasma.
- lipoproteins are involved in different metabolic pathways such as lipid transport, bile acid formation, steroidogenesis, cell proliferation and in addition interfere with plasma proteinase systems.
- HDL are perfect acceptors of free cholesterol and, in combination with cholesterol ester transfer proteins (CETP), lipoprotein lipase (LPL), hepatic lipase (HL) and lecithin: cholesterol acyltransferase (LCAT), play a major role in the reverse transport of cholesterol, i.e. the transport of excess cholesterol in peripheral cells to the liver for its elimination from the body in the form of bile acid.
- HDL not only transports cholesterol from peripheral cells to the liver, but also distributes it to steroid-producing cells or to cholesterol-depleted peripheral cells.
- HDL precursors are secreted in discoid form from the intestine and liver, from which spherical particles are formed through the formation of cholesterol esters which migrate to the heart of the lipoprotein particle.
- the nascent HDL particles contain apo A-l and apo A-IV, while the nascent hepatic HDL particles are rich in apo A-l, apo E and apo A-Il.
- the lipid part of these particles consists of phospholipids and small amounts of free cholesterol and triglyceride. HDL has been shown to play a central role in the transport of cholesterol from peripheral tissues to the liver.
- HDL high-density lipoprotein
- HDL high-density lipoprotein
- the protective role of HDL in reverse cholesterol transport is confirmed by epidemiological studies demonstrating an inverse relationship between cholesterol concentrations in these HDL and the risk of developing coronary heart disease, or by observations that HDL accept effectively excess intracellular cholesterol from various cell types.
- Atherogenic lipoproteins are ingested by macrophages or peripheral cells and degraded in lysosomes. Cholesterol is released from lysosomes and is re-esterified in the cytoplasmic compartment.
- HDLs rich in apo Al stimulate cholesterol flows from macrophages or peripheral cells to the extracellular compartment, following a interaction with HDL binding proteins present on the surface of these cells.
- HDL deficiency Various diseases related to HDL deficiency have been described, including Tangier's disease, HDL deficiency and LCAT deficiency.
- LPL lipoprotein lipase
- apoC-11 activator apoC-11
- RNA molecules were expressed from sequences localized in the genome in a region of approximately 15 cM centered on the microsatellite marker D9S1784, identified as the microsatellite marker giving the binding strongest genetics with family HDL deficiency and Tangier disease.
- region 9q31-34 considered potentially contains genes capable of playing a role in the initiation or the development of various diseases, such as: - bone diseases such as myxoid chondrosarcomas, mental retardations linked to abnormalities of chromosome 9 (MRD);
- NPH2 childhood nephrophtisia
- LGMD2H muscular dystrophy of belts
- schizophrenia - psychiatric illnesses
- the messenger RNAs and the corresponding polypeptides are potentially implicated in some of the human pathologies described above, namely in other pathologies also genetically linked to this region of chromosome 9.
- the present invention thus describes polynucleotides and polypeptides whose alteration of the sequence or expression is potentially associated with a deficit in the metabolism of plasma lipoproteins, more particularly with a deficit in the reverse transport of HDL.
- the present invention also describes polynucleotides and polypeptides whose alteration in the sequence or expression is potentially associated with diseases genetically linked to locus 9q31-34 of chromosome 9.
- isolated in the sense of the present invention designates a biological material (nucleic acid or protein) which has been removed from its original environment (the environment in which it is naturally located). For example, a polynucleotide naturally occurring in a plant or animal is not isolated. The same polynucleotide separated from adjacent nucleic acids within which it is naturally inserted into the genome of the plant or animal is considered to be “isolated”.
- Such a polynucleotide may be included in a vector and / or such a polynucleotide may be included in a composition and nevertheless remain in an isolated state since the vector or the composition does not constitute its natural environment.
- purified does not require that the material be present in a form of absolute purity, exclusive of the presence of other compounds. Rather, it is a relative definition.
- a polynucleotide is in the "purified” state after purification of the starting material or of the natural material of at least one order of magnitude, preferably 2 or 3 and preferably 4 or 5 orders of magnitude.
- the expression “nucleotide sequence” can be used to denote either polynucleotide or a nucleic acid.
- the term “nucleotide sequence” encompasses the genetic material itself and is therefore not limited to information regarding its sequence.
- nucleic acid include RNA, DNA, cDNA sequences or even RNA / DNA hybrid sequences of more than one nucleotide, in single chain form or in duplex form.
- nucleotide denotes both natural nucleotides (A, T, G, C) as well as modified nucleotides which comprise at least one modification such as (1) an analog of a purine, (2) an analog of d pyrimidine, or (3) a similar sugar, examples of such modified nucleotides being described for example in PCT application No. WO 95/04 064.
- a first polynucleotide is considered to be "complementary "of a second polynucleotide when each base of the first nucleotide is paired with the complementary base of the second polynucleotide whose orientation is reversed.
- the complementary bases are A and T (or a and U), or C and G.
- variant of a nucleic acid is meant a nucleic acid which differs from one or more bases with respect to the polynucleotide reference.
- a variant nucleic acid may be of natural origin, such as an allelic variant found naturally, or may also be an unnatural variant obtained for example by mutagenesis techniques.
- the differences between the reference nucleic acid and the variant nucleic acid are reduced so that the nucleotide sequences of the reference nucleic acid and the variant nucleic acid are very close and, in many regions , identical.
- the nucleotide modifications present in a variant nucleic acid can be silent, which means that they do not alter the amino acid sequences encoded by said variant nucleic acid.
- changes in nucleotides in a variant nucleic acid can also result in substitutions, additions, deletions in the polypeptide encoded by the nucleic acid. varying with respect to the peptides encoded by the reference nucleic acid.
- changes to nucleotides in the coding regions can produce substitutions, conservative or non-conservative in the amino acid sequence.
- the variant nucleic acids according to the invention encode polypeptides which retain substantially the same biological function or activity as the polypeptide of the reference nucleic acid or else the ability to be recognized by antibodies directed against the polypeptides encoded by l initial nucleic acid.
- nucleic acids will thus code for mutated forms of polypeptides whose systematic study will make it possible to deduce structure activity relationships from the proteins in question. Knowledge of these mutations in relation to the disease studied is fundamental since it allows us to understand the molecular cause of the pathology.
- fragment will be understood to mean a reference nucleic acid according to the invention, a nucleotide sequence of reduced length compared to the reference nucleic acid and comprising, on the common part, a nucleotide sequence identical to the nucleic acid of reference.
- Such a “fragment” of nucleic acid according to the invention may, where appropriate, be included in a larger polynucleotide of which it is constitutive.
- Such fragments include, or alternatively consist of oligonucleotides of length ranging from 8, 10, 12, 15, 18, 20 to 25, 30, 40, 50, 70, 80, 100, 200, 500, 1000 or 1500 nucleotides of a nucleic acid according to the invention.
- variant of a polypeptide according to the invention is mainly meant a polypeptide whose amino acid sequence contains one or more substitutions, additions or deletions of at least one amino acid residue, relative to the sequence amino acids of the reference polypeptide, it being understood that the amino acid substitutions can be indifferently conservative. or not conservative.
- fragment of a polypeptide according to the invention, is meant a polypeptide whose amino acid sequence is shorter than that of the reference polypeptide and which comprises over the entire part common with these reference polypeptides, a sequence in identical amino acids.
- Such fragments may, if appropriate, be included within a larger polypeptide of which they are part.
- Such fragments of a polypeptide according to the invention can have a length of 10, 15, 20, 30 to 40, 50, 100, 200 or 300 amino acids.
- the "percentage of identity" between two nucleotide or amino acid sequences, within the meaning of the present invention, can be determined by comparing two optimally aligned sequences, through a comparison window.
- the part of the nucleotide or polypeptide sequence in the comparison window can thus include additions or deletions (for example "gaps") with respect to the reference sequence (which does not include these additions or these deletions) so as to obtain an optimal alignment of the two sequences.
- the percentage is calculated by determining the number of positions at which an identical nucleic base or amino acid residue is observed for the two sequences (nucleic or peptide) compared, then by dividing the number of positions at which there is identity between the two bases or amino acid residues by the total number of positions in the comparison window, then multiplying the result by 100 to obtain the percentage of sequence identity.
- the optimal alignment of the sequences for the comparison can be achieved by computer using known algorithms contained in the package of the company WISCONSIN GENETICS SOFTWARE PACKAGE, GENETICS COMPUTER GROUP (GCG), 575 Science Doctor, Madison, WISCONSIN.
- the percentage of sequence identity may be carried out using the BLAST software (BLAST versions 1.4.9 of March 1996, BLAST 2.0.4 of February 1998 and BLAST 2.0.6 of September 1998), using only the default parameters (S. F AltschuI et al, J. Mol. Biol. 1990 215: 403-410, S. F AltschuI et al, Nucleic Acids Res. 1997 25: 3389-3402).
- the query sequence and the databases used can be peptide or nucleic, any combination being possible.
- hybridization conditions described above are suitable for hybridization under conditions of high stringency, of a nucleic acid molecule of variable length from 20 nucleotides to several hundred nucleotides.
- hybridization conditions described above can be adapted as a function of the length of the nucleic acid for which hybridization is sought or of the type of labeling chosen, according to techniques known to those skilled in the art.
- the suitable hybridization conditions can for example be adapted according to the teaching contained in the work of HAMES and HIGGINS (1985) or also in the work of F. AUSUBEL et al (1999).
