    • <p>Using 14M psi(2S) events taken with the BESII detector, chi(cJ) -&gt; 2(K+K-) decays are studied. For the four-kaon final state, the branching fractions are B(chi(c0,1,2) -&gt;.2(K+K-)) = (3.48 +/- 0.23 +/- 0.47) x 10(-3), (0.70 +/- 0.13 +/- 0.10) x 10(-3), and (2.17 +/- 0.20 +/- 0.31) x 10(-3). For the phi K+K- final state, the branching fractions, which are measured for the first time, are B(chi(c0,1,2) -&gt; phi K+K-) = (1.03 +/- 0.22 +/- 0.15) x 10(-3), (0.46 +/- 0.16 +/- 0.06) x 10(-3), and (1.67 +/- 0.26 +/- 0.24) x 10(-4). For the phi phi final state, B(chi(c0,2) -&gt; phi phi) = (0.94 +/- 0.21 +/- 0.13) x 10(-3) and (1.70 +/- 0.30 +/- 0.25) x 10(-3).</p>

  • Genome sequence of Aedes aegypti, a major arbovirus vector.
  • 2007
  • Ingår i: Science (New York, N.Y.). - 1095-9203. ; 316:5832, s. 1718-23
  • Tidskriftsartikel (refereegranskat)abstract
    • <p>We present a draft sequence of the genome of Aedes aegypti, the primary vector for yellow fever and dengue fever, which at approximately 1376 million base pairs is about 5 times the size of the genome of the malaria vector Anopheles gambiae. Nearly 50% of the Ae. aegypti genome consists of transposable elements. These contribute to a factor of approximately 4 to 6 increase in average gene length and in sizes of intergenic regions relative to An. gambiae and Drosophila melanogaster. Nonetheless, chromosomal synteny is generally maintained among all three insects, although conservation of orthologous gene order is higher (by a factor of approximately 2) between the mosquito species than between either of them and the fruit fly. An increase in genes encoding odorant binding, cytochrome P450, and cuticle domains relative to An. gambiae suggests that members of these protein families underpin some of the biological differences between the two mosquito species.</p>

    • The Cancer Genome Atlas (TCGA) Research Network has profiled and analyzed large numbers of human tumors to discover molecular aberrations at the DNA, RNA, protein and epigenetic levels. The resulting rich data provide a major opportunity to develop an integrated picture of commonalities, differences and emergent themes across tumor lineages. The Pan-Cancer initiative compares the first 12 tumor types profiled by TCGA. Analysis of the molecular aberrations and their functional roles across tumor types will teach us how to extend therapies effective in one cancer type to others with a similar genomic profile.

  • Expression of MAC30 in rectal cancers with or without preoperative radiotherapy
  • 2007
  • Ingår i: Oncology. - 0890-9091. ; 71:3-4, s. 259-265
  • Tidskriftsartikel (refereegranskat)abstract
    • <p>Objective: Meningioma-associated protein (MAC30) is overexpressed in several types of cancers, but its therapeutic implication in the patients has not been studied. We examined the relationship of MAC30 with clinicopathological and biological factors in rectal cancer patients with or without radiotherapy (RT). Methods: MAC30 was immunohistochemically examined in 75 distant and 91 adjacent normal mucosa specimens, 132 primary tumours and 39 lymph node metastases from rectal cancer patients participating in a clinical trial of preoperative RT. Results: In the RT group, MAC30 was or tended to be positively correlated with infiltrated growth pattern (p = 0.02), PRL (phosphatase of regenerating liver, p = 0.01) and Ki-67 expression (p = 0.06). MAC30 at the invasive margin of the metastasis was related to poor survival (p = 0.02) in the whole group of patients. MAC30 in primary tumours was not related to recurrence and survival in the non-RT or RT group. Conclusions:MAC30 expression in metastasis was an indicator for poor survival. After RT, MAC30 seemed to be more related to aggressive morphological and biological factors, however, we did not find direct evidence that MAC30 expression was related to the outcome of patients with or without RT.

  • Nup88 expression in normal mucosa, adenoma, primary adenocarcinoma and lymph node metastasis in the colorectum
  • 2007
  • Ingår i: Tumor Biology. - 1010-4283 .- 1423-0380. ; 28:2, s. 93-99
  • Tidskriftsartikel (refereegranskat)abstract
    • <p>Objectives: It was the aim of this study to investigate Nup88 expression in normal colorectal mucosa, adenoma, adenocarcinoma and lymph node metastasis, as well as the relationship between Nup88 expression and clinicopathological features. Methods: Nup88 expression was examined by immunohistochemistry in 84 normal mucosa samples, 32 adenomas, 181 primary adenocarcinomas, and 18 lymph node metastases from colorectal tumour patients. Results: Nup88 expression was observed in normal epithelial and tumour cells. The frequency of strong Nup88 expression was increased from normal mucosa or adenoma to primary tumour and lymph node metastasis (p < 0.0001). There was no significant difference in the expression between normal mucosa and adenoma (p = 0.41). The frequency of strong Nup88 expression was higher in ulcerated tumours (40%) than in polypoid/large fungating tumours (23%, p = 0.048). The frequency of strong Nup88 expression was significantly different among tumours with good (21%), moderate (42%) and poor differentiation (48%, p = 0.01). Nup88 expression was not related to the patients' gender, age, tumour location, size, histological type, invasive depth, lymph node status and Dukes stage (p > 0.05). Conclusion: Our results suggest that Nup88 may play a role during the development, aggressiveness and differentiation of colorectal tumours. Copyright © 2007 S. Karger AG.</p>

  • Increased serum level of Nup88 protein is associated with the development of colorectal cancer
  • 2012
  • Ingår i: Medical Oncology. - Humana Press (Springer Imprint). - 1357-0560 .- 1559-131X. ; 29:3, s. 1789-1795
  • Tidskriftsartikel (refereegranskat)abstract
    • <p>Nucleoporin88 (Nup88) has been shown to be overexpressed in a wide variety of malignancies including colorectal cancer (CRC). However, no study about serum Nup88 in human CRC was reported. Therefore, in this study, we investigated the level of serum Nup88 protein and its relationships with clinicopathological variables in CRC. The serum concentration of Nup88 protein was determined by a quantitative sandwich enzyme-linked immunosorbent assay (ELISA) in 118 pre-operative serum samples, 66 post-operative and 96 healthy controls. Among the patients, the levels of CEA (n = 91) and CA19-9 (n = 87) in the pre-operative serum were measured, and DNA sequencing was performed in 12 CRCs and 2 samples from non-cancerous colon tissue. In the same patients, the level of pre-operative serum Nup88 was significantly higher than that of post-operative Nup88 (P = 0.021). Furthermore, the level of pre-operative Nup88 was positively related to the depth of tumor invasion (P = 0.002) and advanced stage (P = 0.001). The level of pre-operative Nup88 in the left colon tended to be higher than that in the right colon and the rectum (P = 0.063). DNA sequencing results showed that there were two single nucleotide polymorphisms, distributed in exon 6 (NM_002532.3:c.1044Gandgt;A (ACG-ACA, Thr -andgt; Thr) and exon 10 (NM_002532.3: c.1389Aandgt;T, CCA-CCT, Pro -andgt; Pro). Serum Nup88 might be a candidate for a new biomarker implicated in the development and aggressiveness of CRCs.</p>

  • Nup88 mRNA overexpression in colorectal cancers and relationship with p53
  • 2010
  • Ingår i: CANCER BIOMARKERS. - IOS Press. - 1574-0153. ; 8:2, s. 73-80
  • Tidskriftsartikel (refereegranskat)abstract
    • <p>Objectives: We measured nucleoporin 88 (Nup88) mRNA expression in primary colorectal cancers to investigate its relationship with clinicopathological features and p53. Methods: The primary cancer tissues, adjacent noncancerous tissues and the proximal and distant margins of normal mucosa were collected from 73 colorectal cancer patients during surgery. Nup88 mRNA expression was measured on these fresh specimens and on colon cell lines HCT-116 (P53+/+) and HCT-116 (P53-/-) by RT-PCR while p53 mRNA and beta-actin as controls. Nup88 and p53 protein expression were then immunohistochemistrically examined in other 25 colorectal cancers specimens paraffin embedded and formalin fixed. Results: Nup88 expression was higher in primary cancer tissues than in adjacent noncancerous tissues, and in the proximal and distant margins of normal mucosa. Overexpression of Nup88 mRNA was statistically associated with TNM stage (P = 0.044), lymphatic metastasis (P = 0.022), and cancer location (P = 0.036), while not related to gender, age of patients and histological type, infiltration depth, and differentiation of cancers. The expression of Nup88 mRNA in the HCT-116 (P53-/-) cell line was not significantly different from expression in the HCT-116 (P53+/+) cell line. And there was no correlation between Nup88 and p53 protein expression (r = 0.632, P = 0.368). Conclusions: Nup88 mRNA was overexpressed in colorectal cancers and the overexpression was associated with cancer development and aggressiveness. Nup88 might be regard as essential contributor to nodal metastagenicity of colorectal cancer.</p>

  • Overexpression of Id-1 protein is a marker in colorectal cancer progression
  • 2008
  • Ingår i: Oncology Reports. - Spandidos. - 1021-335X .- 1791-2431. ; 19:2, s. 419-424

    • <p><strong>Abstract:</strong> The inhibitor of differentiation/DNA binding 1 (Id-1), a negative regulator of basic helix-loop-helix transcription factors, plays an important role in the regulation of cell proliferation and differentiation. We examined the Id-1 expression by immunohistochemistry in 9 adenomas, 79 primary colorectal adenocarcinomas matched with 40 adjacent normal mucosa specimens and its relationship with clinicopathological factors. The Id-1 expression was increased in the carcinoma compared to the adjacent normal mucosa either in the unmatched and matched samples or to the adenoma. There was no significant difference in the Id-1 expression between normal mucosa and adenoma. The Id-1 expression of carcinoma was increased from Dukes' stages A to B, to C and to D. The cases with lymph node metastasis had a higher rate of a stronger Id-1 expression than those without lymph node metastasis. In conclusion, Id-1 overexpression plays an important role in colorectal cancer progression.</p>
