Abstract: An isolated nucleic acid encoding a C-terminal fragment of paraspeckle component 1 (PSPC1) is disclosed. The C-terminal fragment of the PSPC1 comprises an extension of more than 10 but no greater than 131 amino acid residues with its C-terminal amino acid identical to the C-terminus of the PSPC1 sequence SEQ ID NO: 3 and exhibits a biological activity against tumor cells. The tumor cells are associated with either PSPC1 or protein tyrosine kinase 6 (PTK6), or both. The anti-tumor activity is at least one selected from the group consisting of: (a) suppressing tumor cell growth; (b) suppressing tumor cell progression; (c) suppressing tumor cell metastasis; (d) decreasing PSPC1 expression; and (e) decreasing oncogenic PTK6 expression in cytoplasm. Also disclosed is a peptide comprising a C-terminal fragment sequence of PSPC1. A reagent kit and method for predicting tumor progression, metastasis, and prognosis in a cancer patient are also disclosed.

Abstract: A pharmaceutical composition comprising (i) a therapeutically effective amount of an inhibitor of the oncogene SLC29A2; and (ii) a pharmaceutically acceptable carrier, for use in suppressing proliferation, occurrence, and metastasis of cancer cells overexpressing the oncogene SLC29A2 in a cancer patient, and/or prolonging cancer patient survival. The inhibitor of the oncogene SLC29A2 may be at least one selected from the group consisting of dipyridamole, dilazep, draflzine, nitorbenzylthioinosine, and the derivatives thereof. The composition for use may further comprise sorafenib for the same use.

Abstract: The invention related to the use of high-density loss of heterozygosity (LOH) mapping in lung adenocarcinoma to identify intragenic LOH and driver mutations in different domains of ALK resulted in enhanced tumor growth in xenografted mouse. Mutant (H694R and E1384K) ALKs showed activation of Y1604 ALK and downstream AKT, STAT3 and ERK signaling pathways. Increases of oncogenic signalings resulted in enhanced cell proliferation, colony-formation, cell-migration and tumor-growth in xenografted mouse. Western blot and immunohistochemistry analysis using antibody against phospho-Y1604 ALK on 11 lung cancer cell-lines and 263 cancer specimens indicated ALK activation in all lung cancers regardless of tumor stages. Treating mutant-bearing mice with ALK inhibitor WHI-P 154 resulted in tumor shrinkage, metastasis suppression, and improved survival. Hyperphosphorylation of Y1604 ALK occurred early and continuously throughout tumor progression and could be used as a biomarker to detect lung cancer.

Abstract: The lipoprotein lipase (LPL) gene is associated with hypertension, elevated plasma triglyceride and metabolic syndrome. A haplotype in the intron 3-intron 4 region (the C/AA/T haplotype), and a haplotype in the intron 5-intron 6 region (the GTAG haplotype), are particularly useful in predicting the risk of an individual for these medical conditions. In addition, other markers that display a linkage disequilibrium with either of these haplotypes can also be used in the same manner. The invention can be applied to Chinese, other Asian populations, Caucasian, African American, and other ethnic groups.

Abstract: This invention features a marker set that includes different microsatellite markers corresponding respectively to different genetic loci, wherein a heterozygosity value for each genetic locus is at least 0.50 in the Mongoloid population, and the genetic distance between two adjacent microsatellite markers is in the average of 10 cM.
