  1. 1. TGF-beta signaling in cancer

    Author : Erik Johansson; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TGF-β; proliferation; cancer; tumor suppressor; diffuse-type gastric carcinoma; neuroblastoma; nuclear receptor TLX; cancer stem cell; angiogenesis; ABCG2; VHL; HIF2α; hypoxia; Smad3;

    Abstract : Transforming Growth Factor Beta (TGF-β) is a cytokine regulating a wide range of cellular processes such as proliferation, differentiation, and migration. At the early stages of cancer development TGF-β functions as a tumor suppressor, mainly due to its inhibitory effect on cellular growth, but during cancer progression, mutations in TGF-β signal components switches TGF-β into a promoter of cancer cell proliferation, survival and metastasis.

  2. 2. Studies of human endogenous retroviruses and of the TGF-beta signaling pathway

    Author : Christian Kjellman; Institutionen för experimentell medicinsk vetenskap; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; high-density filter array; gliom; TGF-beta; XA34; Human endogenous retrovirus; HERV-F; transplantation; serologi; Immunologi; serology; Immunology;

    Abstract : The human genome, in common with all mammalian genomes, carries a high load of inheritable retroviral sequences. We have identified and characterized a novel family of these endogenous retroviruses and have named this family HERV-F as based on the primer binding sites of three members. READ MORE

  3. 3. Heparan sulfate dependent cell signaling and associated pathophysiology : Implications in tumorigenesis and embryogenesis

    Author : Tahira Batool; Jin-Ping Li; Aristidis Moustakas; Liliana Schaefer; Ingvar Ferby; Michael Welsh; Anders Malmström; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Heparanase; Glucuronyl-C5 epimerase; Heparan Sulfate; Heparin; Lung Cancer; Cancer cell Singling; TGF-Beta; BMP; VEGF; Notch Signaling; Tumor growth; Metastasis; embryonic development; Medical Biochemistry; Medicinsk biokemi;

    Abstract : Heparan sulfate proteoglycans (HSPGs) consist of a protein core to which several linear, negatively charged heparan sulfate (HS) chains are covalently attached. HSPGs are expressed on the cell surface and in the extra-cellular matrix (ECM) where they have diverse biological functions, for example co-receptor functions. READ MORE

  4. 4. Notch Signaling in Neuroblastoma and Renal Cell Carcinoma

    Author : Jonas Sjölund; Institutionen för translationell medicin; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; differentiation; clear cell renal cell carcinoma; neuroblastoma; TGF-beta; migration; γ-secretase; valproic acid; cancer; Notch; ERK; von Hippel-Lindau; hypoxia;

    Abstract : The Notch signaling pathway governs cell functions essential for normal development and organogenesis. Aberrant Notch signaling has been implicated in tumorigenesis by perturbing control of proliferation, differentiation, apoptosis, migration and angiogenesis. READ MORE

  5. 5. Statistical and Functional Analysis of Genomic and Proteomic Data

    Author : Yingchun Liu; Beräkningsbiologi och biologisk fysik - Genomgår omorganisation; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Bioinformatik; biomathematics biometrics; unsupervised classification; Bioinformatics; medical informatics; TGF-beta; linear mixed model; expression data; dye bias; 2D-gel; signaling pathway; regulatory motif; microarray; medicinsk informatik; biomatematik;

    Abstract : High-throughput technologies have led to an explosion in the availability of data at the genome scale. Such data provide important information about cellular processes and causes of human diseases, as well as for drug discovery. Deciphering the biologically relevant results from these data requires comprehensive analytical methods. READ MORE
