6. Oxygen-dependent regulation of HIF-1alpha expression and function
Sammanfattning : Hypoxia is a state of reduced oxygen levels below normal values. It occurs in the pathophysiology of many diseases and plays important roles in mammalian physiology and development. The hypoxia-inducible factors (HIFs) are transcription factors that mediate adaptive cellular responses to hypoxia by activating the transcription of target genes. LÄS MER
7. Molecular mechanisms underlying the oncogenic function of SS18 and SSX
Sammanfattning : The SS18 and SSX genes were initially identified based on their reoccurrence as fusion partners in synovial sarcoma. As a result of the specific chromosomal translocation t(X:18), the SS18 gene from chromosome 18 becomes fused with members of the SSX gene family on the X chromosome resulting in the generation of a novel chimeric fusion gene SS18-SSX.

8. Identification of novel pathways of regulation of AHR and HIF-1 function
Sammanfattning : Mammalian bHLH-Pas (basic HLH (helix-loop-helix)-PER-ARNT-SIM) proteins belong to the bHLH superfamily of transcription factors. Members of the family have a broad spectrum of functions that among others sense and regulate the cellular response to physiological signals such as low oxygen levels (hypoxia), or environmental signals such as toxins.

9. Functional characterisation of the CAG polymorphism in the androgen receptor- in vitro and in vivo
Sammanfattning : The androgen receptor (AR) is the mediator of androgen actions. In the AR coding region there is a polymorphic CAG repeat encoding a stretch of the amino acid glutamine (Q). The repeat length modulates receptor activity and is normally distributed between 10-30 CAG with a median length of 22 repeats in white men. LÄS MER
10. Structure and function in c-Myc and Grx4 : two key proteins involved in transcriptional activation and oxidative stress
Sammanfattning : The proto-oncogene c-myc is critical for growth and development and deregulation of c-myc expression affects the initiation and expansion of a wide range of human cancers, many of them aggressive. cMyc is a multi-domain protein, where it's C-terminal basic helix-loop-helix leucine zipper (bHLH-Zip) domain heterodimerizes with Max to accomplish gene regulatory activity.
