A novel compound of the formula:wherein ring Q is an optionally substituted pyridine ring;One of R0, R1 and R2 is -Y0-Z0, and the other tow groups are a hydrogen, a halogen, an optionally substituted hydroxy group, a hydrocarbon group that may be an optionally substituted hydrocarbon group or an acyl group;Y0 is a bond or an optionally substituted bivalent hydrocarbon group;Z0 is a basic group which may be bonded via oxygen, nitrogen, -CO-, -CS-, -SO2N(R3)- (where R3 is hydrogen or an optionally substituted hydrocarbon group), or S(O)n (wherein n is to 0, 1 or 2);......... is a single bond or a double bond, or a salt thereof, which has an excellent LDL receptor up-regulating, blood-lipids lowering, blood-sugar lowering and diabetic complication-ameliorating activity.

PCT No. PCT / JP98 / 01225 Sec. 371 Date Sep. 24, 1999 Sec. 102(e) Date Sep. 24, 1999 PCT Filed Mar. 23, 1998 PCT Pub. No. WO98 / 42686 PCT Pub. Date Oct. 1, 1998LDL receptor gene expression promoters containing a 1,2,4-triazine derivative of the formula (I): wherein R1 is optionally substituted phenyl or heterocycle; R2 is optionally substituted phenyl, naphthyl, aralkyl, 5- or 6-membered aromatic heterocycle, alkyl, or alkenyl; X is O, S or NR4; R3 is optionally substituted phenyl, naphthyl, aralkyl, 5- to 6-membered aromatic heterocycle, alkyl, cycloalkyl or alkenyl, provided that when X is NR4, then it may form an optionally substituted nitrogen-containing heterocycle, or a pharmaceutically acceptable salt thereof, which can increase the expression dose (the amount of mRNA) of LDL receptor gene, and thus increase the amount of LDL receptor, and reduce the serum cholesterol level, and are useful in the treatment of hyperlipidemia.

A method for enriching a population of somatic mammary stem cells or mammary tumor stem cells based on low-density lipoprotein receptor-related protein 6 (LRP6). Also included are methods for screening for LRP6 modulators, as well as methods for reducing Wnt signaling, for treating Wnt signaling-related diseases, for detecting mammary basal-like cells, for diagnosing basal-like breast cancer, and for inhibiting proliferation of a tumor expressing LRP6, and compositions thereof.

A method of inhibiting infection by Flaviviridae viruses including HCV, GBC / HGV, and BVD in addition to VSV and any other virus capable of forming a complex with a lipoprotein strategies: preventing formation of a complex should one form, altering the conformation of such a complex to prevent its interaction with the cell receptor, blocking the cell receptor for the complex using an antibody to the receptor, blocking binding of the lipoprotein complex to the cell receptor using soluble lipoprotein receptor or fragments thereof, or downregulating the LDL receptor activity of the cells.

The invention discloses a PCSK9-combined fusion protein which is represented by the following general formula: X-connecting peptide-Y-connecting peptide-Z-connecting peptide-IgG Fc segment, wherein X, Y and Z are EGF(A) region polypeptide mutants in LDL-R (low-density lipoprotein receptor), and the connecting peptide is (GGGGS)n. The fusion protein disclosed by the invention can be combined with the PCSK9 at high affinity to inhibit the PCSK9 from degrading the hepatocyte LDL-R and increase the intake of the hepatocytes for LDL-C, and thus, has obvious advantages and favorable prospects in the aspect of treating hypercholesteremia, familial hypercholesteremia and other diseases.

The invention discloses a construction method of a gene detection library of familial hypercholesterolemia and a gene detection kit and relates to gene mutation of LDLR (Low-Density Lipoprotein Receptor), APOB (Apolipoprotein B) and PCSK9 (Proprotein Convertase Subtilisin / Kexin type 9). In order to ensure that all target regions (including an entire coding region and an alternative splicing regionof a gene to be detected) are covered and prevent a primer dimer or a short segment from being formed between primers of adjacent amplicons, a PCR (Polymerase Chain Reaction) amplification primer isdivided into two independent primer pools; then primer sequence digestion, sequencing connector connection, library purification and quality detection are carried out; finally, the detection library is constructed. The method has the advantages that library establishment steps are simple and rapid, the cost is effectively reduced, the working amount is reduced, variation types are comprehensive, the detection accuracy reaches 100 percent and the flux is high.

Substantially optically pure (S)-trans-{4-[({2-[({1-[3,5-bis(trifluoromethyl)phenyl]ethyl}{5-[2-(methylsulfonyl)ethoxy]pyrimidin-2-yl}amino)methyl]-4-(trifluoromethyl)phenyl}(ethyl)amino)methyl]cyclohexyl}acetic acid, or a salt thereof, or a solvate thereof, which has actions of reducing amount of PCSK9 protein and increasing amount of LDL receptor.
